The microporous structure of the activated carbon fibre KF1500 was investigated by applying a new technique as presented here. This was based on a combination of high-pressure CO2 adsorption measurements between 253 K and 353 K with direct measurement of the differential heats of adsorption at 298 K at low and medium coverages. The validity of this approach was tested by using two activated carbons which has been characterized previously by a variety of techniques, including immersion calorimetry. It appears that a combination of high-pressure adsorption and calorimetry with CO2 alone is a useful tool for the characterization of the whole range of microporosity. This approach confirms earlier observations, according to which the initial stage of adsorption by strongly activated carbons corresponds to adsorption on the walls of large micropores rather than to the primary filling of small micropores.

AbstractA multilayer synthesis of polycrystalline CuInSe2 has been performed by vacuum evaporation with repeat layers thinner than 225Å. Samples deposited with different elemental sequences and repeat layer thicknesses were analyzed by x-ray diffraction as a function of annealing temperature. Samples with 225Å layers produce multiple phases in the synthetic pathway. In samples with thinner layers small amounts of In2Se3 were detected but CuInSe2 predominated. Diffraction and calorimetry data indicate that CuInSe2 and In2Se3 crystallites begin growth at room to moderate temperatures. Layering of samples was probed by grazing angle x-ray diffraction and similarly indicates interdiffusion of layers at room to moderate temperatures.

In this study, a portable and disposable paper-based microbial fuel cell (MFC) was fabricated. The MFC was powered by Rhodopseudomonas palustris bacteria (R. palustris). An activated carbon sheet-based anode pre-loaded organic matter (starch) and R. palustris was used. By using starch in the anode, R. palustris-loaded on the anode could be preserved for a long time in dry conditions. The MFC could generate electricity on-demand activated by adding water to the anode. The activated carbon sheet anode was treated by UV-ozone treatment to remove impurities and to improve its hydrophilicity before being loaded with R. palustris. The developed MFC could generate the maximum power density of 0.9 μW/cm2 and could be preserved for long-term usage with little performance degradation (10% after four weeks).
