Unipolar Barrier Photodetectors Based on Van Der Waals Heterostructure with Ultra-High Light On/Off Ratio and Fast Speed.

Unipolar barrier architecture is designed to enhance the photodetector's sensitivity by inducing highly asymmetrical barriers, a higher barrier for blocking majority carriers to depressing dark current, and a low minority carrier barrier without impeding the photocurrent flow through the channel. Depressed dark current without block photocurrent is highly desired for uncooled Long-wave infrared (LWIR) photodetection, which can enhance the sensitivity of the photodetector. Here, an excellent unipolar barrier photodetector based on multi-layer (ML) graphene (G) is developed, WSe, and PtSe (G-WSe-PtSe) van der Waals (vdW) heterostructure, in which extremely low dark current of 1.

Nutrient uptake and rhizosphere microbial community as related to yield advantage in broomcorn millet‒alfalfa intercropping under different row configurations.

To investigate the effects of row ratio configurations on intercropping advantages and related rhizosphere microbial communities, a field experiment involving five treatments of different rows of broomcorn millet, i.e., P1M1 (1 row of broomcorn millet intercropped with 1 row of alfalfa), P2M3, P1M2, P1M3 and broomcorn millet alone (SP), was conducted on the Loess Plateau of China.

Mobile Application-Based Care on Health Outcomes in Patients With Rheumatoid Arthritis: A Systematic Review and Meta-Analysis.

Background: Effective disease management is crucial for rheumatoid arthritis (RA) patients as it can significantly reduce disease-associated symptoms. Currently, the utilization of mobile applications for managing RA patients has gained widespread popularity in clinical settings. However, there is a notable absence of a comprehensive meta-analysis exploring their effectiveness specifically in the context of RA patients.

Mechanistic insights into SIRT7 and EZH2 regulation of cisplatin resistance in bladder cancer cells.

Cisplatin (CDDP) resistance has been established to significantly impact Bladder Cancer (BCa) therapy. On the other hand, the crucial regulatory involvement of SIRT7 and EZH2 in bladder cancer development is well known. Herein, the collaborative regulatory roles and underlying mechanisms of SIRT7 and EZH2 in CDDP resistance in bladder cancer were explored.
