The electrochemical generation of hydrogen fuel via the proton reduction in the Hydrogen Evolution Reaction (HER) in aqueous media is currently dependent on the use expensive noble metal catalysts for which alternatives must be sought. Molybdenum disulfide (MoS₂) has shown great promise as a suitable electrocatalyst in this regard. While many lab-scale experiments on the HER activity of this ma...

The Directional Recoil Identification From Tracks (DRIFT) detector has recently been proposed [?] to search for dark matter. This detector is unique in that it drifts negative ions, instead of electrons, in a time projection chamber (TPC). A detailed description of the operation, motivation, and other uses of a negative ion TPC (NITPC) can be found in [?]. Briefly, an electronegative component ...

An analysis of the local processes occurring in a trickle-bed bioreactor (TBB) with a first-order bioreaction shows that the identification of the TBB operating regime requires knowledge of the substrate concentration in the liquid phase. If the substrate liquid concentration is close to 0, the rate-controlling step is mass transfer at the gas-liquid interface; when it is close to the value in ...

Schmidt Institute for Meteorology and Geophysics, University of Frankfurt, P.O.

Warm plasma techniques are considered a promising method of tar removal in biomass-derived syngas. The fate another problematic syngas impurity—hydrogen sulfide—is studied this work. It is revealed that processing simulated with microwave results hydrogen sulfide conversion. For different gas flow rates (20–40 NLPM) and concentrations ranging from 250 ppm to 750 ppm, the conversion rate varies ...

Simultaneous exposure to carbon disulfide and noise may have a combined effect on hearing impairment. In this study we investigated hearing loss in 131 men with exposure to noise [80-91 A-weighted decibels; dB(A)] and CS(2) (1.6-20.1 ppm) in a viscose rayon plant. These men were compared with 105 men in the adhesive tape and electronic industries who were exposed to noise only and with 110 men ...

Carbon disulfide has long been recognized as a potent inhibitor of nitrification, and it is the likely active component in several nitrification inhibitors suitable for field use. The effects of this compound on Nitrosomonas europaea have been investigated, and the site of action has been determined. Low concentrations of CS2 (less than 400 microM) produced a time-dependent inhibition of ammoni...

AIM To assess the effects of occupational exposure to carbon disulfide (CS2) concentrations below the threshold limit value (31 mg/m3) on the structural and the functional properties of the arteries, heart rate, blood pressure and lipids. METHODS Study subjects were 85 male workers in the viscose industry and 35 men without such exposure. The CS2 concentration was determined by personal activ...

The social environment plays a critical role in smoking initiation as well as relapse. We previously reported that rats acquired nicotine self-administration with an olfactogustatory cue only when another rat consuming the same cue was present during self-administration. Because carbon disulfide (CS2) mediates social learning of food preference in rodents, we hypothesized that socially acquired...

The synthesis of new indoloannulated thiopyranethiones is reported. key-step a rhodium-catalyzed [2 + 2 2]-cycloaddition alkynyl-ynamides with carbon disulfide to close the pyrrole and thiopyranethione rings simultaneously. A violet idolothiopyrane thione or mixture red isomer result from [RhCl(C8H14)2]2/3BINAP catalyzed cycloadditions, regiochemistry controlled by substitution pattern on alkyn...
