plastic. The first plastic, celluloid, was invented in 1869 by John Wesley Hyatt, (Meikle 5). A $10,000 prize had been offered to anyone who invented a material that could replace ivory for making billiard balls. In his experiments, Hyatt dissolved nitrocellulose and camphor in alcohol. This produced a solid, white material that could be pressed into blocks. The celluloid blocks could then be cut and ground into billiard balls. Mr. Hyatt won the prize and patented his invention (10, 11). For more that
women who wants to be stylish and express themselves in a fun way, buys nail polish. Nail varnishes have many components to make it both safe and user friendly. Some of the chemical components consist of: film forming agents and resins such as nitrocellulose, tosylamide and formaldehyde. Also, plasticizers are used for flexibility and solvents to keep the polish in a liquid form, along with different pigments for colors and shine. There are many more components that go into nail polish that will be
powders and creams. It was by accident that it was discovered that “…boiling nitrocellulose made it soluble in organic
The Cleveland Clinic Fire of 1929 The Cleveland Clinic fire of 1929 was a major structure fire at the Cleveland Clinic hospital on May 15, 1929. The fire was caused by nitrocellulose x-ray film that was too close to an exposed light bulb which ignited the film. This caused two different explosions to occur and also caused poisonous gases to spread throughout the area. The fire caused 123 people to lose their lives, among them was one of the founders of the Cleveland Clinic, Dr. John Phillips. Eighty
difference between bands in each of the protein samples. The western blot is an analytical technique used to detect specific proteins in the given sample of tissue homogenate or extract. The proteins are then transferred to a membrane (in this case, nitrocellulose), where they are stained with antibodies specific to the target protein [1] [2]. This experiment designed to analyze the phylogenetic of four unknown different fish muscles samples in order to predict the type of the aquatic creature. In this
Methyl ethyl ketone is one of the top 100 chemicals produced worldwide due to its high demand and versatile end use. This paper will analyze and compare the production processes of methyl ethyl ketone using patent protected methods of two of the industry’s chemical production leaders, Maruzen Petrochemical Co. and ExxonMobil Corp. The analysis of the two methyl ethyl ketone production methods will enable us to bring to light the evolution of the production process over time and the impact which these
BMI-1 Autoantibody as a New Potential Biomarker for Cervical Carcinoma. The purpose of this study was to determine whether there was any correlation between elevated levels of the BMI-1 autoantibody and cervical carcinoma. In order to determine whether any correlation existed, the levels of the autoantibody BMI-1 in patients who had cervical carcinoma of varying stages and those who did not have cervical carcinoma were compared. Overexpression of BMI-1 has already been associated with certain
Gunshot Residue is the residue deposited on the hands and clothes of someone who discharges a firearm. The ammunition is propelled toward the target by expanding gases that was created by the ignition of smokeless powder or nitrocellulose in a cartridge. The gun shot residue distance can be determined by distance determination. Distance determination is the process of determining the firearm and a target which is usually based on the distribution of powder patterns or the speed
Amelogenesis Imperfecta can be described as a disorder that causes a rare abnormal formation of the enamel (Swootleg, 2007). The Enamel component of teeth is generally comprised of mineral, which is regulated by various proteins within the enamel matrix. People who are diagnosed with Amelogenesis Imperfecta have dentition with abnormal color yellow, brown or grey. There are three main types of amelogeneis imprefecta. They are: Hypocalcified Amelogenesis, persons afflicted with this type of amelogenesis
Not every scientist has affected the lives of every student who studies Chemistry; However, Dmitri Mendeleev’s contribution to science has revolutionized our understanding of the properties of atoms through his development of the Periodic Table. He also studied and researched in many fields such as metrology, geology, physics, and industrial chemistry (Dmitri Mendeleev Royal). Mendeleev devoted a lot of his time to improving the technological advances of Russia. He had pride in his life, work, and
Do you know anything about the history of animation? Animation is all over the world and is with us everywhere in life. Animation is so hard to understand because you don’t know what goes wrong around in animation. Animation can be traced back all the way to the silent age. Animation has developed over the years and has become something incredible as far as technological experience. Being able to play your favorite game on your phone or watching your favorite childhood cartoon are all because of
the right decision every time when you choose your bag for your grocery food or any other junks? The first plastic was created by Alexander Parkes in the 1856. He invented a agile material called Parkesine that make out multifarious mixtures of nitrocellulose, alcohols, camphor, and oils that expansion the first plastic, celluloid. It was an anatomical equipment imitative from cellulose that when it heated could be molded, and the shape will be remains the same when it cool down. Later on, he openly
COSMETOLOGY It is the study and application of beauty treatment. The branches of Cosmetology includes , skin care, cosmetics, manicures and pedicures. TYPES OF COSMETOLOGY The cosmetology is itself is being divided in basically two branches. 1. Decorative cosmetology 2. Remedial cosmetology 1. Decorative cosmetology. This type of cosmetology is basically concerned with enhancing the physical appearance, or protection from the ultraviolet rays. This is also called protective cosmetology. Examples
Innovations of the Industrial Revolution As one of the greatest times of production and change in the quality of life for all classes and members of society, the Industrial Revolution marked a turning point for humankind. Together, the industrial revolutions in both America and Britain not only altered the lifestyles of many, but also offered solutions to many questions that had plagued society for numerous years. Changes that occurred in the fields of medicine and chemistry still play a role
Sequence and structural proteomics involve the large scale analysis of protein structure. Comparison among the sequence and structure of the protein enable the identification on the function of newly discovered genes (Proteoconsult, n.d.). It consists of two parallel goals which one of the goals is to determine three-dimensional structures of proteins. Determine the structure of the protein help to modeled many other structures by using computational techniques (Christendat et al., 2000). This approach
STERILIZATION: Sterilization is the killing or removal of all microbes including bacterial spores which are highly resistant. CLASSIFICATION: Moist heat sterilization. Dry heat sterilization Chemical sterilization. Sterilization is also classified as SUNLIGHT: Bactericidal activity. Germicidal activity because of U V rays + heat. DRYING: Sterilization by dry heat on the other hand requires temperature in range of 1800C for 2 hours.This process is used primarily for glassware . Spores are unaffected

Robert H. Goddard was a scientist, and a U.S. professor of physics. As a child he had many problems with disease. On March 16, 1926, he became the first person in the world to build and launch a liquid-fueled rocket. From 1930 to 1935 Goddard launched rockets that attained speeds of up to 885 km/h (550 mph). Though his work in the field was revolutionary, he was sometimes ridiculed for his theories about space flight. As a child, Goddard was a thin and frail boy who was almost always in fragile
Camphor: A Diminishing Industry of Great Importance Camphor, a member of the Family Lauraceae (Heywood, 1978), is much valued in different parts of the world, particularly in China. This prized botanical has been said to originate in China, but there have been references to Japan, Taiwan and East Asia in similar time periods. Camphor is abundant in mostly sub-tropical countries including India and Ceylon. The camphor tree also thrives in Egypt, the Canary Islands, Argentina, Europe, Florida, California
water, and was evolved in causing lots of dark smoke and pollution. The first useful offical explosive was stronger than black powder and they called it nitroglycerin, which was developed in 1847. As nitroglycerin was unstable, it was replaced by nitrocellulose, a smokeless powdered dynamite and gelignite. In World War I saw the introduction of trinitrotoluene in naval shells. But in World War II it was seen as an extensive use of new explosives. In turn, these have largely been replaced by modern explosives
