Comprehensive force field for multiply-chlorinated hydrocarbons
(Elsevier, 1990)
A force field is presented that has been optimized for chlorinated hyrocarbons containing isolated, vicinal, and geminal secondary chlorines. For carbon--chlorine stretch modes, 74 frequencies in 10 molecules are reproduced ...
Adsorption and thermal decomposition of CH3SH on the Pt(111) surface
(Elsevier, 1993-12-01)
Adsorption, desorption and thermal decomposition of methanethiol (CH3SH) on a clean and on a (2 x 2)-S covered Pt(111) surface have been studied using temperature programmed desorption, high resolution electron energy ...
Polyhedral oligomeric silsesquioxane(POSS)-based polymers
(John Wiley & Sons, Ltd., 1998-10)
A diverse and entirely new class of monomer and polymer technology based on polyhedral oligomeric silsesquioxane (POSS) reagents has been developed. POSS reagents are unique in that they are physically large (approx. 15 14° ...
Observations consistent with autocrine stimulation of hybridoma cell growth and implications for large-scale antibody production
(Kluwer Academic Publishers; Springer Science+Business Media, 1992-04)
Existence of autocrine growth factors (aGFs) may influence the serum requirement for growth of hybridoma cells and thus significantly influence process economics. For the murine hybridoma cell line S3H5/γ2bA2, critical ...
Sonogels and derived materials
(John Wiley & Sons, Ltd., 1999-05)
Nowadays the sol–gel process is used by an increasing number of researchers for the preparation of various products, including bulk materials, films, membranes or fibers. The application of ultrasound (sonocatalysis) to ...
Main-chain poly(arylene ether) phosphonium ionomers
(John Wiley & Sons, Ltd., 1998-10)
Poly(arylene ether) main-chain phosphonium ionomers were successfully synthesized and characterized. The reaction scheme involved first preparing the poly(arylene ether phosphine oxide) by a nucleophilic step or condensation ...
Synthesis and characterization of nanocomposite films with a titania glass matrix by the sol–gel route
(John Wiley & Sons, Ltd., 1999-05)
Films of thickness ∼3 µm containing nanosized metal particles of iron, nickel and copper respectively were grown on a Corning glass slide using a sol-gel technique. The particle sizes had values in the range 6.8 to 20.1 14nm. ...
Processing and properties of (Mo,Cr) oxycarbides from MOCVD
(John Wiley & Sons, Ltd., 1998-03)
A review of the coating kinetics of molybdenum and chromium oxycarbides and a study on the properties of deposited films are reported. Molybdenum carbonyl, chromium carbonyl and their mixture were used to prepare coatings ...
Axial selectivity of 1,2-nucleophilic additions to 2-(Alkylidene)cyclohexanones: Is it higher than that of 2-cyclohexenones?
(Elsevier, 1993-04-23)
2-(Alkylidene)cyclohexanones embedded in steroid systems underwent 1,2-addition of both small and sterically demanding nucleophiles to yield exclusively the axial adducts, supporting the suggestion that 2-(alkylidene)cyc ...
