Do not put water directly on spill however, water spray may be used to knock down the corrosive vapor cloud downwind of the spill area. Cover spill with medium expansion (>30:1) AFFF alcohol compatible foam. Do not allow foam to enter container. Applying foam initially will release significant amounts of corrosive hydrogen chloride vapors which will be reduced when uniform foam blanketing is achieved. For large spills, provide diking or other appropriate contain- ment to keep material from spreading. If diked material can be pumped, store recovered material in appropriate container. Clean up remaining materials from spill with suitable absor- bent. Local or national regulations may apply to releases and dis- posal of this material, as well as those materials and items employed in the cleanup of releases. You will need to deter- mine which regulations are applicable. Sections 13 and 15 of this SDS provide information regarding certain local or national requirements. SECTION 7. HANDLING AND STORAGE Technical measures : Ensure all equipment is electrically grounded before beginning transfer operations. This material can accumulate static charge due to its inherent physical properties and can therefore cause an electrical igni- tion source to vapors. In order to prevent a fire hazard, as bonding and grounding may be insufficient to remove static electricity, it is necessary to provide an inert gas purge before beginning transfer operations. Restrict flow velocity in order to reduce the accumulation of static electricity. Local/Total ventilation : Use with local exhaust ventilation. Use only in an area equipped with explosion proof exhaust ventilation. Advice on safe handling : Do not get on skin or clothing. Do not breathe vapors or spray mist. Do not swallow. Do not get

Received: 2 August 2020; Accepted: 20 August 2020; Published: 24 August 2020 Abstract: A search of the recent literature reveals that there is a continuous growth of scientific publications on the development of chemical vapor deposition (CVD) processes for silicon carbide (SiC) films and their promising applications in micro- and nanoelectromechanical systems (MEMS/NEMS) devices. In recent years, considerable effort has been devoted to deposit high-quality SiC films on large areas enabling the low-cost fabrication methods of MEMS/NEMS sensors. The relatively high temperatures involved in CVD SiC growth are a drawback and studies have been made to develop low-temperature CVD processes. In this respect, atomic layer deposition (ALD), a modified CVD process promising for nanotechnology fabrication techniques, has attracted attention due to the deposition of thin films at low temperatures and additional benefits, such as excellent uniformity, conformability, good reproducibility, large area, and batch capability. This review article focuses on the recent advances in the strategies for the CVD of SiC films, with a special emphasis on low-temperature processes, as well as ALD. In addition, we summarize the applications of CVD SiC films in MEMS/NEMS devices and prospects for advancement of the CVD SiC technology.

Soucek Dr. Sadhan C. Jana ______________________________ ______________________________ Committee Member Dean of the College Dr. Sadhan C.

Newkome ______________________________ ______________________________ Committee Member Date Dr. George G. Chase ______________________________ Committee Member Dr. Chrys Wesdemiotis ii ABSTRACT Siloxanes have been extensively used as additives to modulate surface properties such as surface tension, hydrophobicity/hydrophobicity, and adhesion, etc. Although, polydimethyl -siloxane and polydiphenylsiloxane are the most commonly used siloxanes, the properties are at extremes in terms of glass transition temperature and flexibility. It is proposed that the ability to control the properties in between the these extremes can be provided by cycloaliphatic substitutions at the siloxane backbone. It is expected that this substitution might work due to the intermediate backbone rigidity. In order to achieve the above objectives, a synthetic route was developed to prepare cycloaliphatic (cyclopentane and cyclohexane) silane monomers followed by subsequent polymerization and functionalizations to obtain glycidyl epoxy, aliphatic amine and methacrylate telechelic siloxanes. The siloxanes were either thermally or UV- cured depending on end functionalizations. Chemical characterization of monomers, oligomers and polymers were performed using 1H, 13C, 29Si-NMR, FT-IR and GPC.

The process comprises contacting a mixture comprising methyltrichlorosilane and dimethyldichlorosilane with activated carbon, where the methyltrichlorosilane is selectively adsorbed by the activated carbon. The proc- ess allows for the recovery of a dimethyldichlorosilane fraction reduced in methyltrichlorosilane concentration. The methyltrichlorosilane is recovered by desorption from the activated carbon. The present process is espe- cially useful for removing low levels of methyltrichlorosi- lane present as a contaminate in dimethyldichloro- silane. < CM O <7> CO r»- o Q_ LU Printed by Rank Xerox (UK) Business Services 2.14.7/3.4 EP 0 776 902 A1 Description The present invention is a process for separating methyltrichlorosilane from dimethyldichlorosilane in a mixture.

So far as oligosiloxanes, the topic is especially focused on sila- functional siloxanes as the building block for the synthesis of ladder or cube oligosiloxanes, while the another is the polysiloxanes derived from silicic acid and trimethoxysilanes RSi(OMe)3 which are able to form fibers and flexible free- standing films. The review also refers to the new routes for the selective synthesis of sila-functional oligosiloxanes in addition to the reaction control based on the relative reactivity of sila-functional groups. Finally, the application of polysiloxanes as the precursors to ceramics, high performance coatings, and interlayer low dielectric materials are described. q 2003 Elsevier Ltd. All rights reserved.

For combustion research, the thermal decomposition of benzyl radical, n- alkanes CnH2n+2 (n = 5-8 and 10), 1-butyl radical, and 1-pentyl radical was performed. Benzyl was confirmed to decompose primarily by ejection of H atom after significant isomerization with loss of methyl observed as a minor decomposition pathway.
