Electroactive polymers

device. The circulatory system being tortuous, improvements to endovascular devices are being investigated. Here the process involved in improving this medical field was by combining two technologies together: endovascular devices and ionic electroactive polymers (i-EAP). Medical procedures such as angioplasty, coronary and peripheral, atherectomy, interventional nephrology, interventional radiology, thoracic endovascular aortic repair, full biliary catheter procedure require a skilled physician

Chemical Aspects of Life and Spit Lab Formal Report 1. Abstract The objective of the Reducing Sugar Test was to test if the substance has a reducing sugar in it by adding Benedict’s solution and heating it, there would be a color change if a reducing sugar is present, or it will remain blue (no reducing sugar). The objective of the Starch test was to test for starch in substances by using Iodine. The iodine will cause a substance to turn to a dark blue color if it is positive for starch. The objective

HSC Chemistry Topic 1 PRODUCT ON of MATERIALS What is this topic about? To keep it as simple as possible, (K.I.S.S.) this topic involves the study of: 1. POLYMERS FROM PETROCHEMICALS & BIOMASS 2. ALTERNATIVE FUELS - ETHANOL & THE ALKANOLS 3. REDOX CHEMISTRY & BATTERIES 4. RADIOACTIVITY & ITS USES ...all in the context of society's use of energy and materials but first) an introduction ... In the previous topic in the Preliminary Course, you learnt about carbon chemistry of petroleum Then you

Throughout the 1970s and into the early 1980s, there were as many as 10 other plastic grocery bag designs available, including a flat-bottomed one that could stand on its own. But by 1984 the T-shirt bag was the only style in use. Plastic bags didn 't become cheaper than paper bags until the early 1980s when Windmoeller and Holscher introduced a machine that produced 500 bags a minute and Mobil Chemical challenged Celloplast 's patent the T-shirt bag--and won. In 1982, plastic bags had eight percent

Stability of therapeutic proteins in hydrogel drug delivery systems Abstract: Arthritis constitutes represents one of the major serious conditions that negatively impact affect the patients? quality of life (QoL) of affected patients here in Egypt. Arthritis is associated with comorbid conditions, physical and mental debilitation, increased level of depression and negative influence on life expectancy. Thus, great care is directed to effectively treat this medical condition. Unfortunately, conventional

Biosensor technology has great potential for improving animal welfare, health and production efficiency. The recent increasing incidence of diseases, such as bovine spongiform encephalopathy (BSE), tuberculosis, brucellosis, mastitis, and foot and mouth, has raised concern in the livestock industry and in society. Infectious diseases of livestock have major implications not only in animal welfare and production efficiency but also in human health, and food safety and quality. Most biosensor developments

Composite structure is a combination of two or more different items that may be distinguished physically, resulting in a final product that has a better performance from each component individually done. It consists of matrix composite materials (polymer, metal or ceramic) and one or more stages of reinforcement (fibers, particles, flakes, or fillers). The combination of the different elements appropriately to achieve a system with structural or functional characteristics of the best that can be achieved

in the form of a polymer (Chemistryexplained.com, 2016). The ‘discovery’ of polymers began in 1920, with the belief of Hermann Staudinger, that there existed a molecule consisting of many smaller repeating molecules, under the name ‘macromolecule’ (Chemistryexplained.com, 2016). Nowadays, polymer and plastic demand is even higher than that of copper, aluminium, and even steel, due to their versatile applications in many different industries (Matse1.matse.illinois.edu, 2016). Polymer synthesis can be

Two factors can be used to explain this phenomenon. The first one is the BT particles interact strongly with the macromolecular SR, thus restricting the mobility of the molecular chains. The second one is the polymer chain entanglement limits the movement of polymer chains [38]. The interface polarization will increase the dielectric constant as well as the dielectric loss of the composites. As shown in Figure 4(b), the dielectric loss tangent of the BT/SR composites is larger than that

oxide, wood flour, ivory dust, cellulose and starch. Additives, fillers, and reinforcements are used to change and enhance the physical and mechanical properties of plastics. In general, reinforcing fibers increase the mechanical properties of polymer composites while particular fillers of various types increase
