Pyrolysis and Chemical Vapor Deposition Metal Silicides 

Early studies on H3SiCo(CO)4 and H3SiMn(CO)5 showed that H2 and CO were important volatile decomposition products, and it was at first supposed that the dark residual solid consisted of a highly cross-linked 

It soon became clear, however, that other processes, such as Si-0 bond formation and disproportionation, were occurring, as already discussed in Sections III,F,2 and III,G,1. 

Any disiloxane, (SiH3)20, produced as a result of silicon migration from metal to oxygen (Section III,F,2) will rapidly decompose at 450°C 

Water will be removed by reaction with Si-H bonds.

Organometallic radicals are a topic of special interest due to their reactivity and potential activity in the catalytic realm. There are several methods used to generate short-hved... 

One topic of special interest in Spain is that involving two immiscible phases that form no emulsion such as that in the waste from the three starting phases in the extraction of... 

Recent inventions in micro and nano-scale systems and the development of micro and nano-scale devices continues to pose new challenges, and the understanding of the fluid flow and heat transfer at such scales is becoming more and more important. In Chapter 6, microscale heat transfer is presented as a Topic of Special Interest. 

Ciiapter 6 now has the Topic of Special Interest Microscale Heal Transfer contributed by Dr. Subrata Roy of Kettering Uiiivcrsit, ... 

Most chapters contain a real world application, end-of-chapler optional section called Topic of Special Interest where interesting applications of heat transfer are discussed such as Thermal Comfort in Chapter 1, A Brief Review of Differential Equations in Chapter 2, Heat Transfer through the Walls and Roofs in Chapter 3, and Heat Transfer through Windows in Chapter 9.

It certainly is desirable to have precise values of Reynolds numbers for laminar, tran.sitional, and turbulent flows, but this is not the case in practice. This is because the transition from laminar to turbulent flow also depends on the degree of dislurbatice of the flow by surface roughness, pipe vibrations, and the fluctuations in the flow. Under most practical conditions, the flow in a tube is laminar for Re < 2300, fully turbulent for Re > 10,000, and transitional in between. But it should be kept in mind that in many cases the flow becomes fully turbulent for Re > 4000, as discussed in the Topic of Special Interest later in this chapter. Wlien designing piping networks and determining pumping power, a conservative approach is taken and flows with Re > 4000 are assumed to be turbulent. 

Two topics of special interest in the field of palladium- or nickel-catalyzed crosscoupling of organometals containing zinc, magnesium, aluminium or zirconium are discussed in the next two sections asymmetric cross-coupling and palladium-catalyzed tandem processes. 

The activation of C-C bonds by transition metal complexes has been a topic of special interest in both the inorganic and the organic areas of organometallic chemistry. As a result, the chemistry has progressed significantly over the past... 

Occasionally, a complete volume of Advances in Geophysics will be devoted to a single topic of special interest. This volume, dealing with some of the important physical, chemical, and biological processes occurring in estuaries, does so. The works included here have an additional common feature all are based on studies made in Long Island Sound, which poses problems prototypal of those encountered in many estuarine settings. 

Chapter 3 continues the themes developed in the first two chapters and applies to changes made to equipment. This is a topic of special interest to the FDA because in the processing of semisolid products, the equipment plays a pivotal role. The mixing of drags within the base media is highly affected by the process and mechanism of mixing used. Also, because of the nature of product manufactured, often the cleaning and validation of equipment become serious issues. 

In the author s subjective and rather speculative opinion on the basis of the present performance of electrochemical detection systems, there is sufficient reason to promote further research in this field. Topics of special interest could be as follows ...

Various elementary processes such as oxidative addition, reductive elimination, olefin and CO insertion into the metal-to-carbon bond have found extensive applications in organic synthesis. Other processes such as attack of nucleophiles on metal-bound CO and olefins, unique reactions of metal carbene complexes, and a-bond metatheses are among the topics of special interest to organometalhc chemists as well as to synthetic organic chemists. Our aim is to provide the reader with detailed accounts of elementary processes with the hope that the information provided here is used for further development of molecular catalysis. 

For a deeper understanding of the topology of lignin chains, computer-simulated fractal clusters present a topic of special interest. 

The format of the workshop appeared quite good. Speakers typically introduced a topic of special interest in the area of supramolecular chemistry and presented and discussed recent and unpublished results. This stimulated lively discussions, which continued at an informal level during the intermissions for the coffee-breaks, or at the restaurant. Under these circumstances, there was the occasion for the young participants to present and discuss their projects with scientists of deep experience and international reputation. Moreover, opportunities were offered in particular to people from Eastern European countries for scientific cooperation with groups of American and Western European Universities. 

The topic of special interest is to develop cross-coupling methodology to carry out the reaction between ArX and RSH in water in the absence of organic ligands. Recently, it was reported that thiophenol reacts with phenyl halides in water in the presence of Bu+NBr (TBAB) at 80 °C (Scheme 3.40) [73]. Product yields in the reaction...
