  • The Importance Of Endovascular Devices

    765 Words  | 4 Pages

    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

  • Essay about The Imporance of Polymers Today

    632 Words  | 3 Pages

    A polymer is a large molecule consisting of many smaller subunits known as monomers. There are different types of polymers and many uses for all of them. Even though people may not realize it polymers play an essential role in our everyday life. For polymers range from plastics, PVC, and Styrofoam to key structures in the human body like DNA and proteins which are key components to the human body that makes it possible for each of us to live and be unique. So with out polymers in our body we would

  • Biological Macromolecule Polyhydroxybutyrate ( Phb )

    1447 Words  | 6 Pages

    ABSTRACT The important biological macromolecule polyhydroxybutyrate (PHB) producing Bacillus subtilis was isolated from the sewage sample and identified by means of 16S rRNA analysis. The renewable nature and biodegradability of PHBs make them suitable materials to replace synthetic plastics in many applications. Currently their production is expensive, but these plastics are only in their first stage of commercial development. In the present study the physico-chemical parameters such as Time, Temperature

  • Classification Of Polymers, Cellulose, Starch, And Rubber

     Polymers they are combined form small units of compound having low molecular weight, as a wall is made up of bricks.  The word ‘polymer’ is taken from two Greek words poly states many and (mer) means unit or part.  The term polymer is defined as very large molecules having high molecular mass. These are also referred to as macromolecules, which are formed by joining of repeating structural units on a large scale.  The repeating structural units are derived from some simple and reactive molecules

  • Different Properties Of Polymers That Each Reaction

    725 Words  | 3 Pages

    Discussion The results demonstrated the various properties of polymers that each reaction produced. For the nylon polymerization, a condensation reaction took place and produced a long, polymer string. As described in Figure 1, the product was clear and several meters long, and the fibers held together when stretched. However, when a portion of the nylon string was heated, fibers weakened. The nylon turned a bright white, and, when the stirring rod was used to move the piece, the string broke in

  • Science And Technology Of Designing

    Nanotechnology, which is one of the new technologies, is the science and technology of designing, constructing and creating of novel nano-scale structure, 1nm to 100 nm in size, with huger quality, novel performance properties, along with fewer defects compared with those of the bulk material (Siqueira et al., 2010). An increasing interest from the scientific community to work with materials in nano metric scale has been observed since the introduction of the concept of nanotechnology by Richard

  • Thermo Catalytic Degradation Of Waste Polythene Into Lubricants Using Zeolite

    have been developed to combat this issue which includes pyrolysis and catalytic cracking. This paper states an experiment that was carried out using catalytic cracking using Zeolite (ZSM-5). The catalyst in presence of heat helped to break down the polymer molecules. The experiment gave a product which consisted of 80% grease. The obtained product can be used for various industrial and domestic applications where lubrication is required. The recyclable nature of the catalyst makes this process efficient

  • Structural And Electrical Properties Of Pva Ag Nanocomposite Films

    Structural and electrical properties of PVA-Ag nanocomposite films A .G. El-Shamy, and W. Attia and K.M.Abd El-Kader *, Physics Department, Faculty of Science, Suez Canal University, Ismailia, Egypt ABSTRACT In the present work, PVA-Ag nanocomposite films with thickness 0.18 mm, constant silver content (0.4 wt. %) and with different time of reaction (0.1, 3, 5, 7, 9 h) were prepared by chemical reduction method. Structure, surface topology, photoluminescence and electrical properties

  • What Makes A Plastic Out Of Milk?

    1988 Words  | 8 Pages

    Introduction Can you make plastic out of milk? Is it even possible? It’s true! Milk can be made into plastic. How? Well, all it takes is hot milk and a little bit of vinegar. The main protein found in milk is casein. First this student needs to find out how both plastics are formed, whom was their inventor, what are both plastics used for. There is a lot of background information of casein plastic and regular plastic that needs to be found. So lets get started. Casein Casein is a dairy
