Summary: In this study, a broadband UV photodetector using a p-type NiOx layer and an n-type beta-Ga2O3 heterostructure in PIN configuration is demonstrated for the first time. The optimized NiOx/beta-Ga2O3 PIN photodiode shows good responsivity to incident light wavelengths in the UV-A, UV-B, and UV-C regions. A highly resistive beta-Ga2O3 layer is required for UV-C light absorption, while the NiOx layer provides good photoresponsivity in UV-A and UV-B regions. The results suggest promising device design strategies for wide bandgap semiconductor-based broadband UV PIN photodetectors.

Summary: In this study, a fast-response metal semiconductor metal (MSM) photodetector is fabricated by integrating a polar aluminum nitride (AlN) template with amorphous gallium oxide (Ga2O3). The performance of the photodetector is strongly dependent on the polarization direction of the AlN template. The optimized performance is achieved with a downward polarization from an Al-polar AlN layer, including a lower dark current, higher photo-to-dark current ratio, faster response speed, and recovery time.

Summary: This study conducted an ecological and human health risk assessment of metals and heavy metals in Qinghai Lake, the largest inland saltwater lake in China. The concentration, distribution, and source of these metals were investigated. It was found that the metals in the sediments of Qinghai Lake mainly came from five rivers entering the lake, with copper and zinc showing the highest enrichment capacity. The results of the risk assessment indicated low ecological risks and no threat to human health from the heavy metals in the lake's sediments.

Summary: In this paper, a new dynamic forward model of a multilayered highway structure considering the unsaturated characteristics of subgrade soil is established to assess the dynamic response induced by the falling weight deflectometer (FWD) load. The effects of saturation on stress, displacement, and pore water pressure are analyzed. It is found that the effect of saturation on vertical stress is negligible, while vertical displacement and pore water pressure increase significantly with increasing saturation. The vertical displacement response on the pavement surface is sensitive to subgrade deterioration and variations in material properties.

Summary: This study investigates the dynamic responses of a thermo-poroelastic half-space under circular surface thermal or/and mechanical loads. By considering water seepage and inertia of soil particles and pore water, the governing equations based on Biot's dynamic poroelastic theory are established. Solutions are derived in the transformed domain using Laplace-Hankel transform, and then transformed into the time domain using numerical integration. The resulting dynamic responses of the thermo-poroelastic half-space under rectangular thermal pulse load and/or half-sinusoidal impact mechanical load are graphically presented. The study reveals that both thermal and mechanical loads induce time-dependent responses in the vertical displacements, vertical stresses, and pore water pressures within the saturated poroelastic medium, and the coupled dynamic responses can be obtained by superposing the individual thermal and mechanical responses.

Summary: Phage therapy is a potential alternative to antibiotics for bacterial infections. This study found that storing phages at 4 degrees C was optimal and that 10% dimethyl sulfoxide (DMSO) was more effective in protecting the phages at lower temperatures than glycerin. Additionally, the use of hydroxyapatite and a combination of trehalose with tryptic soy broth or skim milk powder alleviated phage inactivation during storage. Furthermore, a model for predicting phage shelf-life was established with high accuracy using the Accelerated Stability Assessment Program (ASAP) based on the Arrhenius equation.
