The electrical and optical properties of Janus M2S2ClF and its stress modulation function have been systematically studied by first principles method. The stability of the structure was verified by AIMD. The bandgaps of Janus Al2S2ClF, Ga2S2ClF and In2S2ClF under PBE functional are 2.02, 1.03 and 1.22 eV, respectively. The optical parameters show that the Janus Al2S2ClF exhibits high optical absorption coefficient, low reflectance, and low loss function, which has great potential for application in ultraviolet detection and other optoelectronic devices compared with Janus Ga2S2ClF and In2S2ClF. In the strain range of -4% to 4%, it is found that the light absorption coefficient of Janus Al2S2ClF is significantly changed by strain, and the absorption coefficient under -4% stress is 8.9 times that under 4% stress. Meanwhile, the bandgaps of Janus Ga2S2ClF is significantly changed by stress, which can achieve regulation from 0.47 to 2.57eV. Conclusion that the stress has a significant regulatory effect on its electronic and optical properties, which provides a theoretical basis for realizing high performance and controllable optoelectronic devices. © 2025 SPIE.

Solar photovoltaic modules have a single color that cannot meet the requirements of architectural aesthetics. In this paper, starting from the glass cover of thin-film solar cells, to the color-coated glass (coral, green and blue) is prepared by magnetron sputtering with the aid of TFCalc software. TiO2/SiO2/TiO2/SiO2 multilayers with different thickness were prepared with an average transmittance above 73 %. The angle stability of the film color was investigated, and the color stability under different viewing angles can be improved by using high haze frosted glass as the substrate for the preparation of colored films. An average visible transmittance of 75.5 % was obtained in the coral film with the covering of the frosted glass. The use of high haze frosted glass to prepare colored film not only improves the transmittance of coated glass, but also reduces the angle dependence of color film, reduces light pollution, and facilitates the development of industrialization and PV building integration. © 2025 Elsevier Ltd and Techna Group S.r.l.

glass enamel coatings are widely used to protect metal against corrosion and weathering due to their exceptional chemical stability. However, the application potential of enamel coatings will be further enhanced if their mechanical properties, particularly impact resistance and toughness, can be improved. In this study, we investigated the influence of varying amounts of alumina fibers on the microstructure, phase composition, and mechanical properties of enamel coatings by fabricating composite enamel coatings. The impact strength, hardness and modulus of the resulting materials were evaluated by falling ball impact tests and nanoindentation tests. The results showed that the alumina fibers were well bonded to the enamel matrix, and the coating surface roughness and contact angle increased with fiber addition. The coating had the lowest porosity and best impact resistance at 0.5 wt% fiber addition. At this point, the modulus and hardness of the composite enamel coating demonstrated improved stability, with the overall hardness reaching its maximum value, and excessive addition of alumina fibers can lead to a reduction in coating performance. As a result, the alumina fibers appear feasible to use as reinforcing material to produce high performance composite enamel coatings. © 2025 Elsevier Ltd and Techna Group S.r.l.

Fabrication of Ultra-Low Absorption Thin Films via Ion Beam Assisted Electron Beam Evaporation

High Power Laser Science and Engineering 2025年

High-power laser systems require thin films with extremely low absorption. Ultra-low absorption films are often fabricated via ion beam sputtering, which is costly and slow. This study analyzes the impact of doping titanium and annealing on the absorption characteristics of thin films, focusing on composition and structure. The results indicate that the primary factor influencing absorption is composition. By suppressing the presence of electrons or holes that do not form stable chemical bonds can significantly reduce absorption;For amorphous thin films, the structural influence on absorption is relatively minor. Thus, composition control is crucial for fabricating ultra-low absorption films, while the deposition method is secondary. Ion beam assisted electron beam evaporation, which is relatively seldom used for fabricating lowabsorption films, was employed to produce high-reflectivity films. After annealing, the absorption at 1064 nm reached 1.70 ppm. This method offers a cost-effective and rapid approach for fabricating ultra-low absorption films. © The Author(s), 2025.

Structure, mechanical properties, and diffusion kinetics of chemical strengthening ultra-thin aluminosilicate glass by two-step method

引用

Ceramics International 2025年

Chemically strengthening high aluminosilicate glass constitutes a vital component in electronic display devices, and two-step strengthening can further enhance the mechanical properties and stability of conventional chemically strengthening glass. The influence of temperature and time factors on the structure, mechanical properties, and diffusion kinetics of the ultra-thin aluminosilicate glass during the two-step chemical strengthening process was investigated through differential scanning calorimeter (DSC), X-ray fluorescence spectrometer (XRF), Raman spectroscopy, electron probe micro-analyzer (EPMA), and other performance tests. The results demonstrate that as depth increases, the glass structure transitions from loose to more compact, and the extension of the exchange time in the second step will lead to the occurrence of structural relaxation in the glass. The calculation results of diffusion coefficients and activation energy indicate that the diffusion coefficient exhibits three distinct stages as depth increases, the activation energy first decreases and then increases with increasing depth. This may be related to changes in glass structure and concentration gradients. As the temperature for the second step of chemical strengthening increases, both compressive stress (CS) and depth of layer (DOL) exhibit a trend of first increasing and then decreasing. An extension in time leads to a decline in CS but an increase in DOL, which is a consequence of the combined effects of diffusion and stress relaxation. The trends in Vickers hardness and four-point bending strength are identical to that of CS. Although the CS achieved through the two-step method is slightly lower than that obtained by the one-step method, the two-step strengthening glass exhibits superior mechanical properties due to the inward shift of the potassium ion peak and a higher DOL. © 2025 Elsevier Ltd and Techna Group S.r.l.

Herein, a novel preparation of nitrogen-doped carbon (Co/NC) with Co nanoparticles capped onto graphitic carbon nitride (g-C3N4) nanocomposite was developed for detecting the synthetic carcinogenic antioxidant tert-butylhydroquinone (TBHQ). The novel electrochemical sensor equipped with g-C3N4/Co/NC derived by solid pyrolysis of g-C3N4/ZIF-67. Scanning electron microscopy (SEM), X-ray diffraction (XRD) and electrochemical characterizations showed that g-C3N4/Co/NC had the advantages of high electrochemical active area, stable porous framework structure and excellent conductivity. The as-prepared g-C3N4/Co/NC sensor exhibited excellent properties towards TBHQ in a wide linear range (0.05–10 μM and 10–100 μM) with a low limit of detection (LOD = 14 nM, S/N = 3) as well as good sensitivity (5.538 μA·μM−1·cm−2 and 1.043 μA·μM−1·cm−2). Moreover, it was found that the g-C3N4/Co/NC based sensor expressed superior selectivity, reusability and reproducibility. Also, for real sample analysis, food samples like rusk and potato chips were investigated, yielding satisfactory recoveries. © 2025

Journal of Wuhan University of technology(Materials Science) 2015年第3期30卷 512-515页

作者：袁辉平李俊国 SHEN Qiang ZHANG Lianmeng State Key Laboratory of Advanced Technology for Materials Synthesis and Processing Wuhan University of Technology Beijing Glass Research Institute

Zirconium oxide （ZrO：） and boron carbide （B4C） were added to ZrB2 raw powders to prepare ZrB2 porous ceramics by reactive spark plasma sintering （RSPS）. The reactions between ZrO2 and B,C which produce ZrB2 and gas （such as CO and B2O3） result in pore formation. X-Ray Diffraction results indicated that the products phase was ZrB2 and the reaction was completed after the RSPS process. The porosity could be controlled by changing the ratio of synthesized ZrB2 to raw ZrB2 powders. The porosity of porous ceramics with 20 wt% and 40 wt% synthsized ZrB2 are 0.185 and 0.222, respectivly. And dense ZrB：SiC ceramic with a porosity of 0.057 was prepared under the same conditions for comparison. The pores were homogeneously distributed within the microstructure of the porous ceramics. The results indicate a promising method for preparing porous ZrB：based ceramics.
