Emerging Areas

The topic of advanced ceramics is exciting as technologies developed in research laboratories and universities become adopted by industry. This market segment shows continued growth offering good employment opportunities for MS E graduates. 

In this section we will describe three emerging areas ceramic nanopowders, high-temperature superconductors, and ceramic-matrix composites. 

Nanotechnology is a hot research topic. The field is trendy, popular, and high-tech. Although silica and iron oxide nanoparticles have a commercial history spanning half a century or more it is really only within the plast 15-20 years that technologies have been developed for producing ultrapure nanosized powders of a range of ceramics. The 

In January 2001 Pd prices reached a staggering 1000 per troy oz. Currently Pd trades for 330 per troy oz in January 2007.  

Nanosized ceramic powders have grain sizes on the order of tens of nanometers or less conventional ceramic particles typically have grain sizes of several micrometers or more.

This review has covered many of the essential features of the physical chemistry of nanocrystals. Rather than provide a detailed description of the latest and most detailed results concerning this broad class of materials, we have instead outlined the fundamental concepts which serve as departure points for the most recent research. This necessarily limited us to a discussion of topics that have a long history in the community, leaving out some of the new and emerging areas, most notably nonlinear optical studies [152] and magnetic nanocrystals [227]. Also, the... 

Another emerging area m biofuels is pyrolysis, which is the decomposition of biomass into other more usable fuels using a high-temperature anaerobic process. Pyrolysis converts biomass into charcoal and a liquid called biocrude. This liquid has a high energy density and is cheaper to transport and store than the unconverted biomass. Biocrude can be burned in boilers or used in a gas turbine. Biocrude also can be chemical by altered into other fuels or chemicals. Use of pyrolysis may make bioenergy more feasible in regions not near biomass sources. Biocrude is about two to four times more expensive than petroleum crude. 

Fuel cell technology probably offers a new emerging area for polyheterocyclic polymers as membranes. Fuel cells are interesting in transport applications and are now being evaluated in Chicago in transit buses with a 275-hp engine working with three 13 kW Ballard fuel cell stacks. 

Abstract Many similarities between the chemistry of carbon and phosphorus in low coordination numbers (i.e.,CN=l or 2) have been established. In particular, the parallel between the molecular chemistry of the P=C bond in phosphaalkenes and the C=C bond in olefins has attracted considerable attention. An emerging area in this field involves expanding the analogy between P=C and C=C bonds to polymer science. This review provides a background to this new area by describing the relevant synthetic methods for P=C bond formation and known phosphorus-carbon analogies in molecular chemistry. Recent advances in the addition polymerization of phosphaalkenes and the synthesis and properties of Tx-con-jugated poly(p-phenylenephosphaalkene)s will be described. 

An emerging area of interest for the physiological action of the brain of chanokine is the intercellular communication system between neuronal and ghal cells. Indeed, recent in vitro and in situ studies indicated that the chemokines together with then-receptors are constitutively expressed by glial cells and neurons in mature brain (Asensio and Campbell 1999 Cho and Miller 2002 Tran and Miller 2003 Rostene... 

In this review we have attempted to present a unified treatment of this emerging area. By relating the diverse developments we hope that we have succeeded in pointing out some new opportunities for research and innovation and reducing the likelihood of overlaps and rediscoveries. The subject area of this review has hitherto fallen outside the scope of traditional chemical engineering instruction. We hope that this review will stimulate efforts to introduce such material into the classroom. 

The hydrophobicity of these compounds requires protein binding to move carotenoids through aqueous environments an emerging area of research includes the identification of carotenoid transport proteins that determine, in part, carotenoid tissue concentrations. As carotenoids are found throughout nature, various models can be studied for example, Chapter 24 describes carotenoid...

Accordingly, the main potential applications of ACF are as adsorbents and catalysts, as described below. Other possible, smaller-scale applications, in emerging areas such as medicine and power storage, are also considered. 

A major emerging area of research activity in interfacial electrochemistry concerns the development of in-situ surface spectroscopic methods, especially those applicable in conventional electrochemical circumstances. One central objective is to obtain detailed molecular structural information for species within the double layer to complement the inherently macroscopic information that is extracted from conventional electrochemical techniques. Vibrational spectroscopic methods are particularly valuable for this purpose in view of their sensitivity to the nature of intermolecular interactions and surface bonding as well as to molecular structure. Two such techniques have been demonstrated to be useful in electrochemical systems surface-enhanced Raman spectroscopy... 

Other important aspects of modem catalysis including bio- and homogeneous catalysis are beyond the scope of the current book and are themselves the themes of several excellent books. Further, the emerging areas of computational catalysis and immobilized catalysts are not included here but are covered dedicated texts in the literature. 

In summary, during the past five years several inhibitors of HATs have been developed and biologically investigated. They represent interesting tools in the emerging area of epigenetics and may also find applications in experimental antiviral... 

The goal of this proposal is to initiate an extensive research and teaching program in the emerging area of biophysical chemistry. The research focuses on the application of state-of-the-art magnetic resonance techniques specifically designed to investigate... 

Dr. Putnam s review in C E News two years ago ( ) provided an excellent survey of where we were in this area and I am pleased to see that he will be giving the 1985 Sterling B. Hendricks Memorial Lecture later this week. From the abstracts for the presentations that follow this morning, I know that outstanding speakers will present an excellent review of the status of knowledge and of exciting developments in this emerging area.
