A method is described for determining the instantaneous effective energy of x-ray tube brehmsstrahlung by means of two semiconductor detectors employing epitaxial GaAs structures and a measurement circuit, which together determine the effective energy with an error of 5% in the range 20–80 keV in the presence of nonlinearity in the detector response. 相似文献

Phase effects arising in a semiconductor laser with diffraction extraction of radiation and a distributed Bragg reflector
on the substrate side are taken into account exactly quantitatively and the possibilities of using these effects in lasers
is analyzed. It is shown that the phase effects studied can be used to increase the laser efficiency substantially.

Methane oxidative coupling in the presence of the catalyst 1% Au/5% La2O3/CaO and gas-phase initiator hydrogen peroxide at the temperature 700–800°C under normal pressure has been studied. It has been shown that hydrogen peroxide remarkably increases the yield of C2+ products without the loss of selectivity. The maximal yield of C2+ products under the conditions studied was 27% with the formation of a noticeable quantity of benzene. It has been proposed, that the observed effect is due to hydroxyl radical formation from hydrogen peroxide, which could be essential under definite conditions also in a conventional catalytic methane oxidative coupling. 相似文献

Precipitated silica catalysts loaded with either MoO3 (0.2–4.0 wt%) or V2O5 (0.2–5.3 wt%) have been studied in the selective partial oxidation of methane to formaldehyde with molecular oxygen at 520 °C. The functionality of the SiO2 surface towards the formation of HCHO is significantly promoted by V2O5, while it is depressed by the MoO3. 相似文献

The paper theoretically investigates a model of the photosensitivity of porous silicon with cylindrical pores in the condition
of homogeneous generation of photocarriers. Dependences of the photoconductivity of a porous semiconductor on the velocity
of recombination of nonequilibrium carriers at the surfaces of pores, radius of pores and average distance between them are
analyzed. At large velocities of surface recombination the photoconductivity of porous semiconductor is shown to linearly
decrease with increasing the pore’s radius.

A pyroelectrochemical process for reprocessing spent fuel and fabricating granular oxides UO2, PuO2 or (U, Pu)O2 from chloride melts has been developed at the Scientific-Research Institute of Nuclear Reactors for a prospective nuclear fuel cycle. The basic equipment has been developed. The basic results of a comprehensive study of fuel elements with vibrationally compacted (U, Pu)O2 fuel for fast reactors are presented. The performance of the reactors remains high up to 30% burnup in standard BOR-60 reactor fuel assemblies and 32% burnup in experimental fuel elements. An assessment is made of the effectiveness of the pyroelectrochemical methods and vibrational compaction technology for plutonium utilization. 相似文献

Optical manipulation of microscopic objects (including living cells) using Bessel beams from semiconductor lasers has been demonstrated for the first time. In addition, it has been found in the experiments that a Bessel beam of sufficient power from a semiconductor laser makes it possible to manipulate simultaneously several microscopic objects captured into its central lobe and the first ring. 相似文献
