Dye-sensitized solar cells (DSC), introduced by O'Regan and Grätzel in 1991, are a low cost alternative to conventional silicon photovoltaic cells, the latter requiring extremely pure starting materials and sophisticated production procedures. DSC's, based ...
Iron isotopes were used to investigate iron transformation processes during an in situ field experiment for removal of dissolved Fe from reduced groundwater. This experiment provided a unique setting for exploring Fe isotope fractionation in a natural syst ...
Method and apparatus to study biological molecules or biological components at or in self-assembled monolayers (SAMs) on metal surfaces (2) such as gold in aqueous environments (6) using attenuated total internal reflection Fourier transform infra-red (ATR ...
Bench-scale studies were conducted in model freshwater systems to investigate how various parameters affected arsenic removal during coagulation with ferric chloride and arsenic adsorption onto preformed hydrous ferric oxide. Parameters included arsenic ox ...
A review is given of gas absorption which is generally used for the gas with the liq. Gas solubilities and mass transfer concepts used in the design of absorption columns (e.g. Kremser-Brown method), film factor concept, penetration theory, and Chilton-Col ...
This study investigates the composition of free surfaces of neodymium-doped yttrium–aluminum–garnet, using energy minimization techniques. Atomistic modeling shows that the dopant is concentrated in a zone within 0.5 nm ̊of the surface, the enrichment fact ...
The gasification reaction of fir charcoal with CO2 was studied by isothermal thermogravimetric analysis under kinetic control. The derived reaction rate (r = dX/dt) as a function of the converted carbon mass (X) was compared with random pore model predicti ...
The numerical modeling of solutes absorption processes by the arterial wall is of paramount interest for the understanding of the relationships between the local features of blood flow, the nourishing of the inner arterial wall by the blood solutes, and th ...
The adsorption behaviour of Si(111)2 x 1 and Si(111)7 x 7 surfaces towards Fe(CO)5 has been investigated in the temperature range 80-300 K and in the exposure range 0.1-1000 L. For both surface reconstructions, the adsorption state is found to be molecular ...
A gravimetric app. contg. catalyst particles (H2SO4 on silicate) is used to det. the ethylene [74-85-1] absorption rate during the prepn. of vinyl acetate [108-05-4] from ethylene and AcOH. The influence of the absorption process on the overall reaction at ...
