PO Tetrahedron Assisted Chelate Engineering for 10.67%-Efficient Antimony Selenosulfide Solar Cells.

Anisotropic carrier transport and deep-level defect of antimony selenosulfide (Sb(S,Se)) absorber are two vital auses restraining the photovoltaic performance of this emerging thin-film solar cell. Herein, chelate engineering is proposed to prepare high-quality Sb(S,Se) film based on hydrothermal deposition approach, which realizes desirable carrier transport and passivated defects by using tetrahedral PO ion in dibasic sodium phosphate (NaHPO, DSP). The PO Lewis structure, on one hand in the form of [(SbO)(PO)] chelate, can adsorb on the polar planes of cadmium sulfide (CdS) layer, promoting the heterogeneous nucleation, and on the other hand, the tetrahedral PO inhibits horizontal growth of (SbS(e)) ribbons due to size effects, thus achieving desirable [hk1] orientation.

Edaravone Improves Motor Dysfunction Following Brachial Plexus Avulsion Injury in Rats.

Brachial plexus root avulsion (BPRA) is often caused by road collisions, leading to total loss of motor function in the upper limb. At present, effective treatment options remain limited. Edaravone (EDA), a substance that eliminates free radicals, exhibits numerous biological properties, including neuroprotective, antioxidant and anti-inflammatory effects.

Biomechanical Analysis for Enhanced Expulsion-proof Intervertebral Fusion Device.

This study aims to compare the sinking and shifting of an enhanced escape-proof intervertebral fusion device with a traditional TLIF intervertebral fusion device.Five specimens each of the improved escape-resistant intervertebral cage and the traditional TLIF cage were selected. Four types of mechanical tests were conducted on each cage, Furthermore, a blade-cutting torque test was performed on the escape-resistant cage, with the recording of load-displacement curves and mechanical values.

Joint response of surface subsidence and strong mine earthquake under high-positioned and thick-hard strata in deep coal mine.

Multiple active mining faces and extensive excavations under thick-hard strata in deep coal mines result in frequent strong mine earthquakes, often accompanied by significant surface subsidence deformation. Understanding the specific law of surface movement and the spatiotemporal distribution response to intense mine earthquakes is crucial for effectively preventing and mitigating dynamic disasters in deep mines. Utilizing the key layer theory, the intricate strata of the Yingpanhao Coal Mine are systematically delineated, drawing upon the engineering context of working faces 2201 and 2202 within the Ordos Chemical Co.

The compensatory enrichment of sphingosine-1-phosphate on HDL in FSGS enhances the protective function of glomerular endothelial cells compared to MCD.

Glomerular endothelial cells (GECs) are pivotal in developing glomerular sclerosis disorders. The advancement of focal segmental glomerulosclerosis (FSGS) is intimately tied to disruptions in lipid metabolism. Sphingosine-1-phosphate (S1P), a molecule transported by high-density lipoproteins (HDL), exhibits protective effects on vascular endothelial cells by upregulating phosphorylated endothelial nitric oxide synthase (p-eNOS) and enhancing nitric oxide (NO) production.
