Resist research areas

Numerous and disparate copper criteria are proposed for protecting the health of agricultural crops, aquatic life, terrestrial invertebrates, poultry, laboratory white rats, and humans (Table 3.8) however, no copper criteria are now available for protection of avian and mammalian wildlife, and this needs to be rectified. Several of the proposed criteria do not adequately protect sensitive species of plants and animals and need to be reexamined. Other research areas that merit additional effort include biomarkers of early copper stress copper interactions with interrelated trace elements in cases of deficiency and excess copper status effects on disease resistance, cancer, mutagenicity, and birth defects mechanisms of copper tolerance or acclimatization and chemical speciation of copper, including measurement of flux rates of ionic copper from metallic copper. 

One of the fundamental requirements for a high performance anode is to have excellent catalytic activity toward the electrochemical oxidation of the fuel (e.g., hydrogen). This is reflected as low anode polarization or interfacial resistance. This area has seen intensive research for quite some time and is covered very well by the reviews of McEvoy [2], Zhu and Deevi [3], and Jiang and Chan [4], In this section, the focus will still be on revealing the influences of processing and testing parameters on the obtained anode electrochemical performance. 

Other research areas that could improve the effectiveness and economics of flue gas treatment are (1) the development of better instrumentation for system control and (2) the evaluation of superior corrosion-resistant materials. System optimization cannot occur without a good means of system control. Many existing flue gas treatment systems are particularly sensitive to instrument feedback and response. The ability to control closely the operation of these systems could enhance their effectiveness and reliability. The presence of water in flue gas treatment systems... 

Whereas the GST were studied originally because of their involvement in mercapturic acid biosynthesis, these enzymes are also currently of interest to researchers working in fields other than toxicology. Some of the research areas in which GST are of importance include tumor markers, inherited cancer susceptibility, drug resistance, biotechnology, and clinical biochemistry. 

S.N. Lavanya completed her MSc in Botany and MPhil in Seed Technology from the University of Mysore, India and is currently working as a research fellow in the UGC sponsored project. Her research areas include lipid transfer proteins in plant defense, induced resistance in plants, biological control and isolation of biomolecules from plants and microbes. 

Research areas where a chemical engineer can expect to make the most contributions are primarily in resist processing. Here, the major engineering considerations often entail basic conservation laws for mass, momentum and energy, polymer physics, thermodynamics, and transport properties in polymeric matrices. An excellent review has been written by Thompson and Bowden (3) to address the issues encountered in individual unit operations. A few of the many topics discussed in their review will be selected here for a more in-depth examination. Hardware parameters such as lens imperfections, source stability, mask quality and dimensions, contamination and mechanical stability do not fall in the scope of the present discussion. This paper will concentrate on events and research challenges require a firm understanding of material... 

One important area of resist research in recent years is the development of plasma-developable resist systems. The aim of plasma developable resists is to use nonsolvent, all dry development methods to avoid the problems of swelling and consequent resolution limitation associated with conventional resists. Much of the semiconductor fabrication process now utilizes plasma techniques as they are capable of providing high resolution images. An important consideration in this is that the plasma-developable resist images should stand up well to the plasma etching treatments. 

Use of natural fibers is an research area that allows obtain materials for cotidiane applications, using more insistence materials and with outstanding properties and specially materials that are environmental friendly. Keratin is a natural protein which can be found in wool, hair, claws, horns or nails, and is the main component in birds feathers, represents from 5% to 7% of the body weight of chickens. Keratin is durable and resistant to organic solvents and chemically unreactive, which give benefits when is exposure to environmental conditions, thinking in industrial applications.
