The Medi-Can Medicine Alarm & Dispenser is a hexagon-shaped container with a diameter of 12 inches. The container is made of a white plastic. It is lightweight with smooth edges to prevent any hassle for the consumer. The container has a lid that can lift off of the top of the container. The lid is made out of a lightweight, white plastic for easy transportation and lifting. The container is divided into 12 sections by plastic walls inside of the container. These sections are triangular and contain

Discussion Three polymers with industrial applications were produced. Ethylene glycol and glycerol both produced polyesters with thermoplastic properties. These plastics are soft and malleable when heated, but solidify once removed from heat. Thermosetting plastics were obtained from a reaction with phthalic anhydride rather than with a carboxylic acid because it is more reactive. The reaction between phthalic anhydride and ethylene glycol produced the linear polyester. Correspondingly, the reaction

Getting Gooey With Slime Videos Sweeping the world’s social media’s news feed comes quite a sticky uprising trend. From all over the globe, teenagers have fallen in love with gooey, slippery, colorful slime videos. People sticking their fingers in a colorful goo has grabbed the media's attention and is now one of the most popular trends of the internet! Everyone’s favorite childhood toy has made an enormous comeback and is now on market with new creative names and colors. Slime videos are now one

Resin And Shorea robusta Composite Figure 16. Effect Of tanδ at 10Hz Frequency On Polyester Resin And Shorea robusta Composite Figure 17. Cole-Cole Plot Of The Composite At 10 Hz Frequency Cole-Cole plot Linear viscoelastic behaviour of the polymer composite with in the glass transition temperature can be addressed using cole-cole plot. Cole-cole plot is obtained by plotting loss modulus(E”) against

the year 1937 saw the advent of PMMA which replaced vulcanite as it had enhanced properties (Machado et al., 2007). It also was less expensive than vulcanite and aesthetically more pleasing. From then on, PMMA has been in use. Recently, additional polymers such as nylons, vinyl acrylic and light activated urethane dimethymethcarylate have been evaluated for use as denture base materials (Diaz-Arnold et al., 2008). Even if these materials do exhibit very capable properties, none of them have been deemed

The Innovation of War War is an unforgettable event in our history, but through them, they can create some great opportunities to better the future. There have been some remarkable inventions as a byproduct of war, and that has in turn revolutionized our way of life in communication, transportation, and medicine. Many of your everyday items were develop during a time of war, mainly because war has always been an accelerator for technological advancements. It brings the research phase to the utilization

Plasticizing Chemicals: Scientific Perspective In recent years, many questions have arisen concerning the influence of chemicals found in plastics on human health. These chemicals are implemented to give plastics durable, malleable characteristics. Such chemicals include Phthalates, which are added to make plastics more flexible, Bisphenol A (BPA), which is known for toughness, dimensional stability, optical clarity, high heat resistance and electrical resistance (“Polycarbonate Plastics and Bisphenol

The ideal polymers for nanoparticle production must be biodegradable and biocompatible. Moreover, when NPs are produced as buccal delivery systems, the polymers must be mucoadhesive to increase residence time, enhancing the amount of drug that permeates the mucosa and reaches systemic circulation [86]. The mucoadhesion can be obtained either by the formation of electrostatic or hydrogen bonds. Since mucin presents a negative net charge, cationic polymers are preferable for production

are better known in the world of chemistry as polymers, poly meaning many and mers meaning parts. In order for a substance to be classified as a polymer, a compound must be made up of many of these

Polymers are large molecules which comprise of repeating monomers in a single structural unit, and these monomers are bonded by covalent bond to form a polymer. On the other hand, organic polymer is mostly based on a chain of carbon atom alone or with oxygen, sulphur or nitrogen. In order to customize the properties of plastic, different group of
