Glass structures preparation

As will be apparent in Chapter 4, MD simulations have made major contributions to our understanding of the structures and dynamical properties of solids. Problems and processes simulated include phase transitions (e.g. Impey et al., 1985 Meyer and Ciccotti, 1985), orientation dynamics in molecular crystals (e.g. Dove and Pawley, 1984) and ionic and diffusion (e.g. Gillan and Dixon, 1980 Vashishta and Rahman, 1978). In addition, they have been used to study melting and, as noted above, to prepare glass structures by a simulated melt-quench cycle as described by Vessal in Chapter 12. 

The nanofibrous structures prepared from dilute polymerization have no significant change when dedoped and redoped multiple times by base and acid solutions, respectively. The dispersion in deionized water of nanofibers is stable for several minutes without aggregation and precipitation [239]. Furthermore, a highly porous film of nanofibers is obtained as the dispersion is cast and dried on the glass or silicon wafer substrates. The UVA is absorption patterns of polyaniline nanofibers obtained are consistent with previously reported results for conventionally synthesized polyaniUne. 

This calcium aluminate fiber was evaluated in structural applications but it was not suitable for the evaluation of infrared optical properties because it contained bound water as evidenced by a strong hydroxyl band at 29 jjm in the IR transmission spectra. Hydroxyl-free compositions were made in carbon crucibles [17] by the Davy process [39], i.e., by a procedure [40] by which disposable optical calcium aluminate bulk glasses are prepared for commercial applications in optical windows. 

This chapter presents the design, sputtering (synthesis), bacterial evaluation, and surface characterization of Ag-nitride films on cotton and polyester fabrics. Film preparation was optimized for the most suitable inactivation kinetics of E. coli taken as a standard probe, because disinfection kinetics is a major parameter to consider for the potential application of these films in textiles, thin polymer films, glass structures, walls, and metal plates. The approach taken was to seek the systematic, detailed, and comprehensive investigation of a nitride that would be kinetically fast during bacterial reduction. Ag-TaN was found to be a faster Ag-nitride compared with Ag-ZrN and Ag-TiN, respectively, in that order. 

Prepared generally by ester interchange from polyvinylacelate (ethanoate) using methanol and base also formed by hydrolysis of the acetate by NaOH and water. The properties of the poly(vinyl alcohol) depend upon the structure of the original polyvinyl acetate. Forms copolymers. Used as a size in the textile industry, in aqueous adhesives, in the production of polyvinyl acetates (e.g. butynal) for safety glasses. U.S. production 1980...
