Nitrocellulose

has written to illustrate the history of plastic. One of the first forms of plastic was nitrocellulose, which was made by mixing wood pulp with nitric acid. In its liquid form, collodion, it can easily be dyed just by dropping a few drops of ink into the solution. The exploration of plastic owes its roots to the game of pool that was made popular in the 19th century. At that point, ivory was the primary material of production for the balls used in the game. Ivory is hard enough to withstand many high speed collisions without chipping, is tough enough to not crack; allowing it to be made into a spherical shape, and it was easily dyed. However, it was also very expensive. Nitrocellulose was used as a coating for wooden balls, in an attempt to replicate the ivory balls but at a fraction of the cost. With further experimentation, it was found that nitrocellulose mixed with naphtha creates a solid, named celluloid by John Wesley Hyatt.. Thus, objects made purely of plastic was now possible. The portrayal of the journey of plastic through a screenplay allowed also the portrayal of societal and judicial issues surrounding the material. Change is good, but not everyone can accept change. The introduction of the collodion balls were received with mixed feelings. On an economic scale, it was much cheaper to produce and was much more accessible to saloons all around the world. However, nitrocellulose is highly flammable. Given the amount of force some players may apply to striking…

The nitrocellulose piece was first submerged in nanopure water. Then, the blot sandwich was assembled in a tray of transfer buffer. One side of the transfer clamp was placed on the bottom of the tray and filled with transfer buffer. One Scotchbrite pad was submerged onto the bottom of the transfer tray. A piece of blotting paper was submerged onto the pad. The gel was then removed from the cassette and the top left corner was clipped. The gel was laid on top of blotting paper with the clipped…

backfire, likely killing the operator(s) of the weapon. Scientist heard these concerns and quickly developed superior alternatives. By the mid-1800s, the first “smokeless” gunpowders were developed. Nitroglycerin and guncotton, a nitrocellulose-based material, were discovered to be a powerful alternative to the black powder that produced negligible smoke and residue. Nitroglycerin addressed most of the major concerns with black powder, but was extreme unstable, often shattering the gun rather…

polar stationary phase over which non-polar solvents are used as mobile phase; it is generally used for separation of non-polar species.[38]. A detection system is coupled with HPLC to detect and quantify the constituents. 3.4.2. Method development HPLC is state of art equipment which can separate and detect constituents of For the HPLC analysis of a particular mixture, a system is to be developed. Developing a system for analysis is a function of the constituents of the analyte. System…

possible color and translucence. Nail polish , women love it, girls love it. But what exactly is it made of? From syl amide resin to stearalkonium bentonite, ingredient names sound more like a top secret formula for NASA, than a recipe for nail polish. Each of these ingredients play a part in the overall performance of the polish. Polish typically consists of eight major ingredients. Polymers, often referred to as the “backbone” consists of two main chemicals. Tosylamide Formaldehyde…

scale gunpowder production in the United States. Guncotton, also known as nitrocellulose, was invented in 1845 by German chemist Christian Schonbein. The purpose of this invention as to create a propellant for military weapons but soon realized that guncotton was extremely fast and had the potential to be very dangerous. However, in 1860, the Prussian army utilized guncotton into a tiny cartridge creating a bullet. By 1880, guncotton replaced…

The nitrocellulose is rinsed in the water, and then the clamp was placed in the Tupperware container filled with running buffer with the Scotchbrite pad. Two sheets of blotting paper was placed on the Scotchbrite pad then the gel was placed on the blotting paper with the nitrocellulose paper the top of it. Two more pieces of blotting paper were then added on top of all the sandwich followed by another Scotchbrite pad. Finally, the group closed the clamp on the apparatus then submerged the…

Some flame and a huge amount of smoke will be liberated from the rapidly burning sugar. The chemical formula of the reaction is described as below: 48KNO3 + 5C12H22O11 → 24K2CO3 + 24N2 + 36CO2 + 55H2O There are two ways the smoke bombs can be made at home. The first way is as mentioned above in the experiment. The second way involves using celluloid material which is a transparent flammable plastic made in sheets from camphor and nitrocellulose. Nowadays, ping pong balls are commonly used to…

the idea to Qatar. Part B A series of explosions took place in the industrial Chinese port city Tianjin, a densely populated area that is home to over 13 million people (Insurance Information Institute). The blasts took place on August 12, 2015 and claimed the lives of a total of 173 people and injuring thousands more. The cost of insurance payments to the affected parties ranged from between USD 2.5 – 3.5 billion, making this the costliest insurance settlement in Asia. According to CNN, the…

of Kansas began experimenting some years ago with a black powder substitute. after much expense and explosions that killed some of its employees, Hodgdon now manufacturers a black powder substitute called Pyrodex that is available at gun shops and sporting goods stores.” Our text went on to say that “Pyrodex is a pyrotechnic composition that is best described as replica black powder. it does not contain nitrocellulose, nor is it a smokeless propellant. rather, it is a propellant designed for…
