How to Make Chemical Piranha Solution

Chemical piranha solution or piranha etch is a mixture of a strong acid or base with peroxide, mainly used to remove organic residue from glass and other surfaces. Its a useful solution, but hazardous to make, use, and dispose of, so if you need to prepare this chemical, read over the precautions and disposal advice before you get started. Heres what you need to know: How to Make Piranha Solution There are multiple recipes for piranha solution. The 3:1 and 5:1 ratios are probably the most common: 3:1 concentrated sulfuric acid (H2SO4) to 30% hydrogen peroxide (aqueous H2O2) solution4:1  concentrated sulfuric acid to 30% hydrogen peroxide solution5:1  concentrated sulfuric acid to 30% hydrogen peroxide solution7:1 concentrated sulfuric acid to 30% hydrogen peroxide solution (less common)base piranha: 3:1 ammonium hydroxide (NH4OH) to hydrogen peroxide Prepare the solution in a fume hood and be certain you are wearing gloves, a lab coat, and safety goggles. Put the visor down on the hood to minimize the risk of damage or harm.Use a Pyrex or equivalent borosilicate glass container. Do not use a plastic container, as it will react with the solution and eventually fail. Label the container before preparing the solution.Make certain the container used for mixing is clean. If there is excessive organic matter, it may cause a vigorous reaction, possibly leading to a spill, breakage, or an explosion.Slowly add the peroxide to the acid. Do not add acid to peroxide! The reaction will be exothermic, may boil, and may splash out of the container. The risk of boiling or of sufficient flammable gas being released that could lead to an explosion increases as the amount of peroxide increases. Another method used to prepare piranha solution is to pour sulfuric acid over a surface, followed by peroxide solution. After time is allowed for the reaction, the solution is rinsed away with water. Safety Tips   Make piranha solution fresh before each use because the solution decomposes.Activity of the solution is increased by heating it, but dont apply heat until after the reaction to make the solution has completed. Its advisable to let the solution cool slightly after reaction before heating it.Do not leave hot piranha solution unattended on the lab bench.Do not store piranha solution in a sealed container. For that matter, do not store chemical piranha for later use, period.In case of skin or surface contact, rinse affected area immediately with large volumes of water. Continue rinsing at least 15 minutes. Seek appropriate emergency aid.In case of inhaling, remove affected person to fresh air and seek emergency medical aid. Be aware symptoms of exposure may be delayed.In case of suspected ingestion, seek immediate medical attention. How to Use Piranha Solution To Clean Sintered Glass - Piranha solution is used to clean sintered glass or fritted glass because it doesnt damage pores in the glass (which is why you dont use a strong base instead). Soak the glassware overnight in piranha solution before rinsing it with water.To Clean Glassware - Piranha solution can remove contamination on glassware that is untouched by other chemicals. Its important there is not excessive organic contamination. Soak the glassware overnight, then thoroughly rinse it.Apply as a surface treatment to glass to make it hydrophilic. Piranha solution increases the number of silanol groups on the glass surface by hydroxylating the silicon dioxide.Apply to remove residue from surfaces. Make sure you are removing residue and not a significant layer of material! Disposal of Piranha Solution To dispose of piranha solution, allow the solution to cool completely, to allow for it to release oxygen gas. Make sure the gas has dissipated before proceeding.Neutralize piranha solution by diluting it with large amounts of water. Do not neutralize it by adding a base, as the rapid decomposition releases heat and pure oxygen gas. The exception is when the volume of piranha solution is small (~ 100 ml). Then, dilute the piranha by adding it to water until it is less than 10% of the volume. Add sodium hydroxide or sodium carbonate solution until the pH is 4 or higher. Expect heat, bubbling, and possibly foaming when the base is added to the acid solution.Usually, its okay to wash diluted piranha solution down the drain. However, some places prefer it be treated as toxic waste. Disposal also depends on the purpose of the solution, since some reactions may leave toxic residue in the container. Do not dispose of piranha solution with organic solvents, as a violent reaction and explosion will occur. Source Kemsley, Jyllian (January 16, 2015). Piranha solution explosions.

Boy in the Striped Pyjamas Free Essays

Bruno’s diary Year 1943, age 9 years old as I was born on the 15th april 1934. Day one of strange happenings: Today I came home from school and maria was in my bedroom going through MY things – Even my secret things. She is just a servant but I tried to be polite when I asked what she thought she was doing. We will write a custom essay sample on Boy in the Striped Pyjamas or any similar topic only for you Order Now Maria never takes all my private things out, she puts things away like she’s supposed too. I asked mother why maria is packing my things but she won’t answer me properly. She just keeps saying we are all going away because of father’s job. She said I’ll have to say goodbye to my friends, my best long life friends. I don’t want to say goodbye to my friends because of father’s job. I know he’s important but why can’t father go by himself and come back later? It’s not fair. I still have lots of plans with my friends that I need to do. I wonder if grandma and grandfather are coming on this holiday too? We can’t really leave them behind†¦though I don’t mind if Gretel stays – shes hopeless. Gretel can look after the house so we can come back to it if this new one isn’t as good. I wonder if the other house has a big bannister like this one that I can slide down? I hope so because it’s my favourite thing to do. Day two of strange happenings: We are at the new house and it’s horrible! It only has three floors, not five like the other one and there are no other children around to play with. I don’t like this place but mother won’t take me back home, she says this is where we live now but I don’t want to live here. Gretel doesn’t like it either, or maria, so it definitely is a horrible place to live. I’ll just have to tell father what a mistake he’s made and then we can all go back home to berlin. Even the people here are scary and boring, like that man that came out of fathers room today. I don’t think I like him†¦he’s too serious. Maria says to steer clear of him anyway. Day three of the horrible place: I scared Gretel today when I showed her the weird children outside my window. She is three years older than me and quite scary, so scaring her isn’t an easy thing to do. I don’t know why she has come with us anyway, all she does is cause trouble. That’s what mother and father say anyway. At least her friends can’t come round anymore. She has horrible friends that call me six when I’m actually nine! She still has her dolls though. I bet they spy on me when I’m in her room, so I don’t go in there much. Gretel said father said we are going to stay here for the foreseeable future, whatever that means. Gretel thinks it’s about 3 weeks, so at least it isn’t a month I suppose. She doesn’t like this place either though so maybe we will move back sooner. Day four of the horrible place: The people outside my window are still there. Gretel thinks that we are in the countryside and that they must be farmers. I don’t think they are farmers though because there are no animals and the ground is all brown and dirty. It doesn’t look like a nice place anyway, there are soldiers shouting at people and for some reason everyone is wearing pyjamas. I wish Gretel knew who they were and would tell me. She’s the brightest girl in her class apparently. I found them though, so they are my people, not hers. I am a high and mighty king in my bedroom and they are my minions that Gretel can’t have. I shall have to ask father what they are doing there and why they don’t have baths. I’ll know more than Gretel then, even though she’s older. Day five: Father came to the house today. We had to leave earlier than father on the train. There were a lot of other people coming this way on the train too†¦but they were all on one big train squashed together. I don’t know why they didn’t just come on the same train as us because we had lots of empty seats they could have used. I was very brave today and asked father when we were going home because it’s horrible here. I thought father would get very angry because I’m not supposed to go into his office or waste his time saying hello or asking silly questions. Father said we have to do things we don’t like though because other people know what’s best for us. He said we have to accept the situation we find ourselves in and then everything will become easier†¦or something like that. I still don’t like it here though and it will never be home. I don’t know why father can’t see that he’s made a mistake. I even told him to apologise to the fury and then we can go back to berlin. Father is a very respectable man but I still think he is wrong. Why doesn’t he just listen to us instead of his job? Extract from chapter 12, pages 128 – 129 †¦we had to move to a different part of Cracow, where the soldiers built a big wall and my mother and father and my brother and I all had to live in one room†¦Ã¢â‚¬ËœThere was one small window in it but I didn’t like to look out of it because then I would see the wall and I hated the wall because our real home was on the other side of it. And this part of town was the bad part because it was always noisy and it was impossible to sleep†¦Ã¢â‚¬ËœThen one day the soldiers all came with huge trucks†¦ And everyone was told to leave the houses. Lots of people didn’t want to and they hid wherever they could find a place but in the end I think they caught everyone. And the trucks took us to a train and the train†¦ The train was horrible†¦ There were too many of us in the carriages for one thing. And there was no air to breathe. And it smelled awful. ’ Shmuel’s exposition provides necessary background information that allows the reader to identify with the character. In this particular extract, the author conjures a lot of imagery to convey emotion and mood, which is implemented through structural and lingual techniques. Ellipses are used repeatedly throughout the extract, creating a pause, which causes the reader to consider and empathise with the characters ordeal. It also contributes to the rhythm of the paragraph, setting a slow and deliberate pace, evoking heightened emotions of fear and apprehension. The simplistic language, combined with alliteration delivers a childlike and innocent approach, which draws sympathy from the reader in relation to the child’s traumatic experience. For example, the ‘soldiers built a big wall’ contrasts against shmuel and his family living in a small room, emphasising how small and vulnerable they are. The use of repetition such as the train is effective in this extract, as it creates a sense of urgency and distress, helping to set a despondent atmosphere. This atmosphere is intensified with short sentences and a hyperbole toward the end of the paragraph (There was no air to breathe) for a dramatic impact. The boy in the striped pyjamas is a fable based on the holocaust. The protagonist of the story, Bruno, comes home from school one day to find his belongings packed and told to say goodbye to his friends due to his dads promotion. Mourning his old home Bruno sets out exploring areas he shouldn’t – his naivety and inquisitive innocence, lead him to the outskirts of a concentration camp, where he befriends a boy just like himself, albeit religious boundaries. It is this friendship between two young boys that leads to a cruel twist of fate. The hamartia of bruno, in this case his innocence, leads to his downfall. It is somewhat ironic, that the innocence and accepting nature of a child is essentially a weakness that leads to a cruel fate, whilst those that deserve misfortune are without tragedy. It also conveys a moral, classifying this book as a fable. In relation, Romeo and Juliet by William Shakespeare share the same themes as the boy in the striped pyjamas. Innocent characters lose their lives unnecessarily because of events that are out of their control, caused by prejudice and discrimination. Another similar feature between the two novels is that Shakespeare uses dynasties/houses to create differences and segregation between parties. In correspondence, the author of the boy in the striped pyjamas, uses clothes to create differences and symbolise their status in society. For example, the striped pyjamas indicates inferiority, weakness and suffering of the jews, whilst the uniforms of the soldiers uphold authority, cruelty and dominance. As opposed to Shakespeare, what makes this book so despairing and emotive is the reality of it. It is not a romantic, fictional play based on lust and fate – it is representative of real events where horrific tragedy’s took thousands of innocent lives for reasons due to nothing but social status, discrimination and prejudice. It can be argued, that such events would not have occurred in reality; firstly, historical records show that more than 6000 soldiers were present in the aushwitz camp, making it unlikely that a child could escape their notice to sit at the edge of a camp and talk to an outsider. Secondly, most women and children were gassed upon their arrival, leaving the men to work. Another point raised, is that most credible 9 year olds have a lot more common sense in reality than is portrayed in this fable. Boyne’s story depends on the overwhelming naivety of his character, who is completely oblivious to the war despite his father working for Hitler. In conclusion, for a short fable aimed at children, I believe it to be a powerfully emotive tale that strikes key points. The innocence and reality of the events that took place in the book make it that much more touching, horrific and powerful. How to cite Boy in the Striped Pyjamas, Essay examples

This stage demands the person to put the experience jack together and also identify the main process occurring within the experience (Glister, 2003). During the semester, I was asked to do literature review. At that time I was totally unaware about literature review. According to Hart (2005) literature review is a process of reading, analyzing, evaluating and summarizing scholarly materials about a specific topic. Since literature review was a new topic for me, initially, found it very difficult.Additionally, after the first summarize feedback I found referencing and academic writing style also was the real matter of concern. The challenges facing international dents in todays academic environments across the secondary, tertiary, graduate and postgraduate levels is growing (Gibbering researcher, 2010) I am now going to enter the second stage of the Gibbs (1988) model of reflection, which is a discussion about my thoughts and feelings. Before my first submission, I was really confident about my topic and writing skills. We will write a custom essay sample on Reflective Report or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page However, after feedback I have become, depressed and lost. Due to the lack of understanding, I was upset with the entire marking system. At the some point had many doubts about successful completion of course. Students may have active outlooks about the university life and course, due to low grades which they obtain in their initial stages of the studies (Gibbering researchers, 2010). Evaluation is the third stage of the Gibbs (1988) model of reflection. In this stage reflector explain what were good and bad experiences about the event (Caller, 2008).Once I came to know my drawbacks, initially I was in a denial mood. However, gradually I accept my weakness and try to find out a solution to overcome. I started to set goals and be disciplined enough to reach those goals by the deadline. I kept a small notebook and wrote down ACH day what I needed to do in each class. Believe the best positive experience of this event being able to organize my time for studies and work. One of my weaknesses was. I have been afraid to ask for help, as this course progressed, I overcome this issue.I realized in the academic world everyone helps each other. In addition, have enjoyed this semester because it opened my eyes to who really as a person. I have become more confident and goal oriented. Stage four of Gibbs (1988) is analysis of the event, where Gibbs encourages the reflector to make sense of the situation (Brooke et al,2003). In the following days after the feedback, I had an opportunity to have one to one section with both public and learning development unit module leaders. They gave some valuable instructions and academic reading exercises to improve my writing style.Referencing is the most important factor in academic writing (Mason, 2003). My mentor gave a new Harvard referencing format in order to improve my referencing. So that it will help me to improve my grades and also keep myself away from plagiarism accusation. As an international student these sections were a new experience. Moreover during he sections educators were really supportive and encouraging, which helped me to boost up my confidence. Student mentors can be invaluable to students who are struggling with a variety of issue in university campus (Highly, 2010).Furthermore, it also helped me to understand the issues which was facing in my academic writing. In addition, before the course I was not given much importance for my writing skills. For instance, my tutors pointed out that my punctuation and expression in writing were below the average. Punctuation marks are a set of symbols with specific rules for the usage of ACH one. Complete meaning of the sentence depends on the punctuation that is used in the sentence (Scudded, 2009). In conclusion, stage five of the Gibbs (1988) model, through the assignment submission and feed backs.I have improved my referencing as well as my academic writing skills and also be learned to be more goals oriented and organized. In future there are lot of improvement needed in my academic area. Furthermore, need to improve my critical thinking skills. I need to organize my writing skills in the more academic way. Within my action plan, I am planning to reduce my part time irking hours and concentrate more on studies and also attend regular one to one section with module leaders, so that I can do weekly briefing and improve my skills on a daily basis.To conclude, my reflection skills have developed through the production fifths essay. Using Gibbs model of reflection has helped me to structure my thoughts and feeling appropriately.

Jane Eyre And Fanny Price Essays - British Films,

Jane Eyre And Fanny Price A comparison between Jane Eyre and Fanny Price There are many things that can be compared between Jane Eyre and Fanny Price, and I will focus on the fact that they are both orphans that grow up to be independent women. The two are so different yet also so much the same. In the following analysis, I will compare these two characters and decide who can be viewed as the stronger character. To start, we can say that both Jane and Fanny are orphans. They are both sent to live with family and destined to become outcasts from the start. Jane is not readily accepted by her family. This is also true of Fanny. They are only similar in the fact that they are orphans. Fanny's character is different from Jane because Jane is an independent individual. Fanny is much more reserved and independent, while Jane has a much more outspoken personality. Jane Eyre struggles to resist those around her from changing her. Her self-devotion causes her many sufferings, but she survives these and becomes a stronger woman. Jane grows up in a Victorian period where women were not seen as equals. She was born an orphan into a family that had no more room to love another child. Jane faced much resentment in the house, but being the strong-minded character that she is, she confronts Mrs. Reed. She says, "I am not deceitful: if I were, I should say I loved you; but I declare that I do not love you: I dislike you the worst of anybody in the world." Jane Eyre grows up questioning authority. She is an independent soul with an independent mind. She will not tolerate being walked over. She shows her strength in all aspects of her life including her love for Rochester. The fact that she is an orphan shows us how the absence of a mother contributes to the void of nurturing, therefore, giving the character possession of internal strength and independence. In Mansfield Park, Fanny can be seen as an orphan as well. She is sent to Mansfield to live with her relatives because her mother is unfit to take care of her. She grows up at Mansfield rejected by her Aunt and as an outcast among her cousins. She is independent but not outspoken. She only finds true friendship with Edmund. She struggles in the beginning to overcome her homesickness, and her longing for her relationship with her brother. Edmund is the only vice that sees her through her struggle. She is not as outspoken as Jane, but she is as strong-minded. She knows what she wants and if she could stand up for herself, she can obtain it. Her determination helps her to gain strength. Self-respect dominates the theme of Jane Eyre, whereas in Mansfield Park the story deals with more moral issues concerning class and family. In Jane Eyre, the idea of gender and class structure is very evident between Jane and Rochester. She is a hardworking governess and he, her much wealthier employer. In Mansfield Park, Fanny's interest in Edmund also tests society. For any kind of interest in each other would be wrong during that time. The story itself tests society in ways of the characters going against the "duty" of their lives. For example, Edmund is jumping out of the lineage by wanting to become a clergyman. Also, his attraction to Fanny and hers to him was considered immoral in 19th century England because of their relationship. Returning back to Jane, we can see how society could feel that her romance with Rochester was wrong. But even Jane is independent enough to leave him when he threatens her beliefs. She remains true to her beliefs, no matter what. Even when that means spending three days wandering around and almost dying for her choices. One theme that remains true to both novels is that both stories defy the norms of society. In Mansfield Park, the characters go against all duties and the idea of the structure of family. The theatrical in the book even furthers their attempts to do everything against what it right and moral at that time. In Jane Eyre, there are some problematic issues with gender and class structure. Throughout both novels, Jane and Fanny remain true to themselves, which proves to be no small accomplishment. They both struggle with difficult issues. They do not present a picture of achieving freedom, but yet the dangers of defying societies conventions. Although both stories capture the strength

rev Week 6 Final Paper

rev Week 6 Final Paper rev Week 6 Final Paper Space Age Furniture Problem University Name Abstract The Space Age Furniture Company appropriated a requisition of 1000 Gemini furniture pieces and an alternate for 1000 Saturn furniture pieces. The unit that will generate they said units is equipped for gathering the handling of the requested products, however the quandary is the accessibility of a gifted worker who can proficiently work the extraordinary machine required in the processing of a particular part to finish an unit. The main mechanic of the organization can prepare 30 bits of said part in a hour, 240 pieces in a general 8 hour work day, or what added up to 1,200 pieces in a 5 working days for every week. Anyhow to take care of the demand of the customer for a particular date of conveyance, 2,000 units must be made in one week. Ed, the main gifted machine admin is hesitant to work more extra minutes. In this way, the furniture organization is confronted with the issue of conveying the requested units asked for by the customer on a particular date and influencing Ed to work additional minutes throughout the whole weeks of processing. The organization has one week lead opportunity to transform both requested items. Space Age Furniture Problem Struggling to meet the client satisfaction, by effectively balancing production of goods with employee contentment is always a problem to producers of goods. Take the case of Space Age Furniture Company. The company has only one machine operator who can operate the special lathe that will produce part number 3079 needed in the completion of both Genesis 425 and Saturn 257, part 3079 is essential in the production of both commissioned products. But this essential part is only produced by the special lathe which only Ed can skillfully operate. With Ed opting to work the regular shift, 8 hours in five regular working days, only 1,200 pieces will be made in a week. But with the higher demand for the products and the time element included in the order, more of part 3079 must be produced per day which would translate to overtime work for Ed, if he agrees to it. Hiring another machinist to take over the production after Ed’s shift ends, may yet solve the p roblem but the special lathe requires a highly skilled operator like Ed, to work it efficiently, and not a lot of Ed’s caliber can be immediately hired to do the work. Another alternative is a training anew operator, but that will not be good option, considering that the new recruit may not turn out to be as skilled as Ed. â€Å"With Coral, the operations manager of the company is tasked to address the problem of solving the timely and efficient production of the specific part without the burden of overtime to the only available operator of the lathe† (Gallego G, 2011) Detailed study of demand must be studied comprehensively, that is, in the total of 2,000 units of part 3,079 that must be produced to meet both orders, 1,000 sub-assemblies is for Saturn 257 and the other 1,000 sub-assemblies is for Genesis 435. Every assembly unit is generated by Ed at pretty nearly 0.03 hours, or an unit at regular intervals, 30 gathering units each hour, in an eight hours shift 240 units, so in 5 days and with a 8 hours shift a day, 1200 sub get together units will be processed in a week. Ed, the engineer, supposes whatever he can process is the greatest 1200 sub gathering parts for the week, in any case, 2000 parts or an overabundance of 800 sub get together parts must be processed without much fanfare, which implies that 26.6 hours of extra minutes work must be rendered to take care of the demand of the employment request. The organization has an one week lead opportunity to transform the requested furniture, so what the operations chief needs to do is let Ed produce the greatest number of the aforementioned parts without doing extra time work expecting that the organization has not yet accepted the requests. The prepared parts might then be the organization's stock that might

Sociology Research methods - Essay Example According to Article 26 of the ICCPR, all persons are entitled to equal protection under the law with regards to rights in general, whether or not they are set out in the Covenant on the grounds described in that provision†. A workplace consisting of more than at least 3000 employees provide a wider spectrum of people for survey and research. The technological developments during the past decade in information technology, innovative software applications, inventions in computer hardware and advanced networking technology gave rise to the growth of BPO, software companies and investments and trading in international level necessitated movement of talents from place to place, and in this backdrop the current study has become important. The Research Questions The survey is designed to collect data from the participants for a study with reference to the following pertinent research questions in relation to the research. Whether the cultural interaction in the confluence of various ethnic groups in a country could be construed as strength instead of weakness by the society? Can unity in diversity be achieved? Hypothesis The analysis of the survey results would be useful in evaluating the hypothesis or the problems involved in the integration or racial issues in the society and the key hypothesis is: When the world is moving toward liberalization, and the countries pursue a policy of globalization, rich and diversified cultural background of the country would lead to economic growth and peaceful co-existence on account of international implications in the growing fields of telecommunications, social networks, internet and media due to its hold on international communities. Sampling Identification of target population and sampling frame needs to be done carefully. Simple random sampling method is proposed to be employed with probability sampling scheme to ensure that every group in the population has been covered, as it would be appropriate and representative of the population. The scope and organization of Survey Saris & Gallhofer (2007, p.4) state â€Å"Survey research is often used for descriptive research. †¦ studies can also be done to determine the reasons †¦ such research is called explanatory research†. The important aspects involved in the process of research include sample size, source of data, experience and communication skills of the data collector depend on the type of research. The active support of the management of the organization where the survey is planned to be conducted and hence preliminary discussions and continuous interaction throughout the survey process with them is essential. Inadequacies in resources and facilities would affect the quality of research and vitiate the results.
