Southeast Sulawesi. The research sample, all participants of Latsar Group II amounted to 40 people. Collecting data using questionnaires and assignment sheets. Data analysis was univariate and bivariate, using paired T test. The results of the study found that the average pre-test 77.8 (satisfactory) and the post test 85.6 (satisfactory), there was an increase in the value of 10.02%. The results of the paired T-test obtained a significance value of 0.000 <0.05, this means that there is a significant difference in the average value of respondents, before and after online learning. It can be concluded that online learning for PNS accountability training is considered effective in achieving learning objectives. Although the online learning method has several shortcomings, but the learning objectives are considered to be achieved effectively, the researchers suggest that the online learning method for the further PNS Accountability training can be carried out in both new normal and normal conditions.

Abstract
The β-Ga2O3 ultraviolet (UV) detectors work in the solar-blind (UV) band due to the ultra-wide bandgap of β-Ga2O3. In this paper, a solar-blind ultraviolet detector based on an ordered nanoporous β-Ga2O3 (ONP-β-Ga2O3) film is proposed and implemented. The local enhancement effect of the ordered nanopores on light is simulated by finite-difference time-domain method, and the period and diameter of the nanopores are optimized. Graphene is transferred on the ONP-β-Ga2O3 film and prepared as interdigital electrodes of the solar-blind ultraviolet detectors. The optimal detector has a photo-to-dark current ratio of about 4.64 × 103 at a 5 V bias, a peak response of 2.43 A W−1 at 254 nm, and a UV/visible rejection ratio of about 1081. We demonstrate that the ordered nanoporous structure can localize optical field effectively, which results in enhancement of light absorption as well as improvement of key detector parameters.
Fabrication of solar cells with CO2 gas sensing capabilities based on a NiO/ZnO p-n junction for developing self-powered gas sensors
Authors: Hamada Tomohiro , Sugiyama Mutsumi 
Published: February 2022

Abstract
Solar cells based on a NiO/ZnO p-n junction structure responding to CO2 gas were fabricated by conventional RF sputtering. The developed NiO/ZnO solar cells exhibited evident photovoltaic effects and response to CO2 gas when exposed to sunlight at room temperature without thermal heating or external power supply. The open-circuit voltage, generated by the solar cells absorbing only UV light, increased in a CO2 atmosphere and decreased in air. Moreover, the response mechanism of the NiO/ZnO solar cells to CO2 gas was investigated using electrochemical impedance spectroscopy. The results suggested that the depletion layer width of the NiO/ZnO interface changed under CO2 gas with light illumination. These results represent the potential application of the NiO/ZnO p-n junction structure toward self-powered gas sensors.

Published: February 2022

Abstract
The far-infrared emission properties of epitaxial graphene on SiC obtained by current injection were investigated using an infrared camera and Fourier-transform infrared spectroscopy. The radiation directivity from the graphene emitter was observed in the directions perpendicular to the surface and edge of the sample. The emission energy density from the graphene edge was larger than that from the graphene surface in all directions. The maximum measured temperature change at 0.4 W for the edge emission was 76.1 K for a tilt angle of 50° and that for the surface emission was 54.1 K for 0°. A blackbody-like emission spectrum with a constant peak wavelength of 10.0 μm, regardless of the applied electrical power, was observed for both the surface and edge. A far-infrared light emitter was successfully realized using single-crystal graphene on SiC.

In JSC “URIR named after A. S. Berezhnoy” chromia refractories for the lining of pool and feeder of glass-making furnaces for the production of glass fiber from E glass, which are in contact with the glass melt, and alumina-chromia-zirconia-silica refractories with 30 % Cr2O3 for service in the topsides of these furnaces, in areas affected by components of the glass batch and glass melt, have been developed and manufactured. The main raw material for the chromia products manufacturing is metallurgical chromium oxide. In the manufacture of alumina-chromia-zirconia-silica products, metallurgical chromium oxide or a mixture of metallurgical and pigment chromium oxide in a ratio of 2 : 1 is used as the chromium oxide component of the batch. The testing of new materials, such as a new grade of chromium oxide, in the technologies of chromia and alumina-chromia-zirconia-silica refractories is relevant.
The effect of a new grade of chromium oxide on the properties of chromia refractories has been investigated. It was found that samples of a new grade of chromium oxide, pressed at optimal values of moisture content of the mass and specific pressing pressure, are characterized by a low apparent density of the raw material in comparison with samples made of metallurgical chromium oxide. After firing, samples from chromium oxide of the new grade are not inferior to those of metallurgical chromium oxide in terms of properties, but they have large changes in linear dimensions during firing, which can lead to the formation of cracks, therefore, the issue of obtaining chromia products from mixtures with the replacement of metallurgical chromium oxide with chromium oxide of the new grade in order to increase the apparent density of products requires additional research.
A study on the effect of new grade of chromium oxide on the properties of alumina-chromia-zirconia-silica refractories with a content of 30 % Cr2O3 has been carried out. It was established that, in the batch for the manufacture of these refractories, containing metallurgical and pigment chromium oxide, it is possible to completely replace the pigment chromium oxide with chromium oxide of the new grade or to increase the content in the batch of chromium oxide of the new grade instead of a part of metallurgical chromium oxide to the ratio of metallurgical chromium oxide and chromium oxide of the new grade 1 : 2.
