TL;DR: In this paper, the results of both Fourier transform infrared spectroscopy and zeta potential measurements confirm that a readily apparent number of Lewis acid sites composed of mainly carboxylic acid and cyclic acid anhydrides were derived on the surface of thermally oxidized nanodiamond (T-ND).

TL;DR: Excess volumes of the binaries: acetone + benzene and acetone+ cyclohexane, and for the ternary, have been determined from density measurements at 298.15 K as discussed by the authors.

TL;DR: A two-stage cascade with cell recycling and turbidostatic cell concentration control turned out to be the best solution, the first stage of which was kept at relatively low cell and product concentrations.
Abstract: To increase the solvent productivity of the acetone-butanol fermentation, a continuous culture of Clostridium acetobytylicum with cell recycling was used. At a dry cell mass concentration of 8 g l-1 and a dilution rate of D=0.64 h-1, a solvent productivity of 5.4 g l-1 h-1 was attained. To prevent degeneration of the culture, which occurs with high concentrations of solvents (acetone, butanol and ethanol), different reactor cascades were used. A two-stage cascade with cell recycling and turbidostatic cell concentration control turned out to be the best solution, the first stage of which was kept at relatively low cell and product concentrations. A solvent productivity of 3 and 2.3 g l-1 h-1, respectively, was achieved at solvent concentrations of 12 and 15 g l-1.

TL;DR: In this paper, the effects of solvent temperature and solvent flow rate on phenol desorption were evaluated and it was found that solvent volume and type were the most important factors in phenol deodorization.
