Development of new generation

Up-to-day reliability requirements as applied to NPP strength maintenance govern development of new generation of computerized systems for in-service inspection. These systems in parallel with capabilities of ordinary ultrasonic techniques allow to reconstruct high resolution image of inner flaw and increase available amount of information. 

The continued development of new single-source molecular precursors should lead to increasingly complex mixed-element oxides with novel properties. Continued work with grafting methods will provide access to novel surface structures that may prove useful for catalytic apphcations. Use of molecular precursors for the generation of metal nanoparticles supported on various oxide supports is another area that shows promise. We expect that the thermolytic molecular precursor methods outlined here will contribute significantly to the development of new generations of advanced materials with tailored properties, and that it will continue to provide access to catalytic materials with improved performance. 

The rise in environmental concern, coupled with the enormity of some oil spills in the recent past, has led to the development of new generations of oil spill dispersants. 

Chirality at surfaces can be manifested in a number of forms including the intrinsic chirality of the surface structure and even the induction of chirality via the adsorption of achiral molecules onto achiral surfaces. The ability of STM to probe surfaces on a local scale with atomic/molecular resolution has revolutionized the understanding of these phenomena. Surfaces that are globally chiral either due to their intrinsic structure or due to the adsorption of chiral molecules have been shown by STM to establish control over the adsorption behavior of prochiral species. This could have profound consequences for the understanding of the origin of homochirality in life on Earth and in the development of new generations of heterogeneous chiral catalysts that may, finally, make a substantial impact on the pharmaceutical industry. 

Since zeolite catalysts are successfully introduced in the refining and petrochemical industries, it is not surprising that most of the recent advances concern incremental improvements of existing processes with the development of new generations of catalysts (e.g., dewaxing, ethylbenzene and cumene synthesis). The number of newer applications is much more limited, for example, direct synthesis of phenol from benzene and aromatization of short-chain alkanes, etc. However, both the improvement and development of processes contribute significantly to environmental advances. 

The progress in understanding TGF-fl signaling roles and mechanisms resulted in applications in medicine and biotechnology, including artificial intervention into stem cell growth and differentiation, or development of new generations of pharmaceutical compositions for tissue restoration and treatment of such diseases as cancer, cardiovascular or renal dysfunctions, and immune disorders. 

In this chapter, we discuss the important role played by some key natural products in malaria chemotherapy. We focus on naturally occurring secondary metabolites that had substantially affected the control and treatment of malaria. Advances in the total synthesis of these compounds and derivatives, and their implications in new strategies for the development of new generation of antimalarial drugs are also discussed. 

Statistical mechanics and computer simulations have contributed to the development of new generations of equations of state, which in contrast with those discussed so far, have a more sound theoretical basis. 

The Aspidosperma family of indole alkaloids has inspired many synthetic strategies for the construction of their pentacyclic framework of the parent compound aspidospermidine (366), since the initial clinical success of two derivatives, vinblastine (10) and vincristine, as anticancer agents. The alkaloids such as (-)-rhazinal (369) and (-)-rhazinilam (6) have been identified as novel leads for the development of new generation anticancer agents [10,11]. Bis-lactams (-)-leucunolam (370) and (-t-)-epi-leucunolam (371) have bio-genetic and structural relationships with these compounds [236]. Recently, enantioselective or racemic total syntheses of some of the these natural product were achieved. One successful synthesis was the preparation of the tricyclic ketone 365, an advanced intermediate in the synthesis of aspidospermidine (366), from pyrrole (1) (Scheme 76) [14]. The key step is the construction of the indolizidine 360, which represents the first example of the equivalent intramolecular Michael addition process [14,237,238]. The DIBAL-H mediated reduction product was subject to mesylation under the Crossland-... 

Taking this circumstance into account some above topics will be analyzed lower in more details. Namely, these are limiting hardening created as a result of obtaining ultra-fine grains, some topics of deformation hardening additionally, considered will be some aspects of development of new generation of titanium-based materials (systems Ti-B-X and Ti-Si-X, where X is Al, Zr, etc.).

Dendritic cells (DC) are important antigen-presenting cells (APC) that can prime naive T-cells and control lymphocyte-mediated adaptive immune responses with respect to magnitude, memory, and self-tolerance. Understanding the biology of these cells is central to the development of new generation immunotherapies for cancer and chronic infection. 

At the same time, surfactants like alkylbenzene sulfonates remain the most widely used basis for laundry detergents. Anionics remain the main products for making detergent compositions. Some of the application aspects of relatively new types of anionics (a-olefin sulfonates, sulfocarboxylic acids, alkyl phosphates etc.), whose commercial manufacture began in the 60-ties - 70-ties of the 20 century, are described by Stache [95]. The application of conventional types of nonionics like ethoxylated alcohols or alkyl phenols is presented in [13 -14], Alkyl polyglycosides were widely used in the last 5-8 years [96]. However, the main tendency in the development of new generation detergents is the use of surfactant mixtures in their optimum composition [97, 98].
