An enzyme electrode is described based upon the enzyme lactate oxidase (EC 1.1.3.2) coupled to an H2O2 sensor. Use of an organosilane-treated microporous membrane over the enzyme layer, allows responses linear to 18 mmol/l L-lactate with response times of 1-3

This work describes a very simple, rapid, and efficient approach to the hydrophobization and lipophobization of cellulose fibers through their reaction with gaseous trichloromethylsilane (TCMS). The characterization of the modified surface involved FTIR-ATR and solid-state (29)Si NMR spectroscopy, scanning electron

Structures and energies of the gas-phase species produced during and after the various unimolecular decomposition reactions of methyltrichlorosilane (MTS) with the presence of H2 carrier gas were determined using second-order perturbation theory (MP2). Single point energies were obtained using singles
