Electroactive polymers

Nanoparticles are used because of their versatility in targeted drug delivery while minimizing toxicity. Gold is used as the basis for nanoparticles because it has a relatively high stability of ligand binding along with its decreased stability with other cells. Gold nanoparticles (AuNPs) also have a high concentration of glutathione, which is an antioxidant that prevents damage to cells from things like free radicals and peroxides. We are using AuNPs to carry drugs to cells infected with the Human

learn, learn and relearn until my end. My decision to apply for MS polymer engineering has emerged, both from my passion for research and my aspiration to understand the language of energy generation. I felt polymer engineering footholds the entire world. This makes it one of the most challenging fields of the present generation. It has the power to create novel designs in the field. I keenly wish to contribute more towards the polymer engineering to this field by acquiring the practical knowledge and

Department - Escola Americana de Campinas Campinas – SP, Brazil Introduction Plastics are, by definition, “a class of material that has one or more polymers as its primary ingredient, that is shaped by flow when it is processed (usually using heat), and that is solid in its final form.” They’re usually composed of a combination of polymers, plasticizers, and one or more additives, according to GreenPlastics.com. By changing ingredients or quantities of each s[1] Plastics are used everywhere

resistance and long life. Compared to metals, composites can be easily made by relatively low tooling cost. Polymer matrix reinforced by woven fabrics is probably the most commonly used form of composites in structural application such as aircrafts, boats, and automobiles

Polymer composites are the blend of polymers and filler materials. Disadvantages of polymers such as low mechanical and electronic properties can be improved through reinforcing with much stronger and highly conducting filler materials. Thus, fabricating polymer composites is of mutual benefit to both polymers and fillers. Furthermore, advanced-desired applications can be tailor-made. Also, compared to polymer micro/nanocomposites, polymer nanocomposites show much more improved properties such as

The major advantage of these thermoplastic modifiers is that their incorporation into epoxy resins does not result in reduction in modulus and glass transition temperature. In comparison with rubber modified systems, the use of tough thermoplastic polymers offers better improvement in fracture toughness for higher crosslink density epoxy systems. The advantages of thermoplastic modified epoxy systems lie in the fact that the modulus and the Tg of the modified epoxy can be maintained, and the fracture

silicone or ethylene vinyl acetate. The efficacy is maximized at lower doses and the side effects are less. The ring contains the drug spread throughout the entire matrix. The rate of release of the drug depends on: i. The solubility of the drug in the polymer ii. The surface area of the ring iii. The capability

tension of the fluid. As the solvent evaporates, fibers with diameters ranging from several microns to several hundred nanometers can be formed [184]. The diameter of the fibers can be regulated by modifying the flow rate and concentration of the polymer, and altering the distance

down into poly, meaning many, and ester, a basic organic chemical compound. Polyester is a really strong fabric that is resistant to stretching, shrinking, and wrinkling, therefore making it more durable. Originally, Polyester began as a group of polymers in W.H. Carothers’ laboratory. However, once Carothers discovered Nylon all further experiments were dropped. In addition, British scientists John Whinfield and James Dickson continued this work in 1939, inventing a Polyester fabric known as Terylene

Literacy Task 1 PRODUCING BIODEGRADABLE PLASTIC JUST GOT CHEAPER AND GREENER The topic of this report is that producing biodegradable plastic just got cheaper and greener. What this report is about and how it relates to the society, technology and the environment will be discussed. Biodegradable plastic is plastic that is capable to decompose through the action of living organisms. It is originally from renewable resources and made from natural materials such as corn starch. Biodegradable plastic
