2D Perovskite Heterojunction-Based Self-Powered Polarized Photodetectors with Controllable Polarization Ratio Enabled by Ferro-Pyro-Phototronic Effect.

Metal halide perovskites (MHPs) are commonly used in polarization-sensitive photodetectors (PDs) for applications such as polarization imaging, remote sensing, and optical communication. Although various methods exist to adjust the polarization-sensitive photocurrent, a universal and effective approach for continuous control of MHPs' optoelectronic and polarized properties is lacking. A universal strategy to electrically modulate the polarization ratio (PR) of self-powered polarized PDs using the ferro-pyro-phototronic effect (FPPE) in 2D perovskites is presented.

The clinical impact of recent amphetamine exposure in aneurysmal subarachnoid hemorrhage patients.

Background: Amphetamines possess sympathomimetic properties that can affect cerebral vasculature though conflicting reports exist about their effect on vasospasm risk and clinical outcomes in aneurysmal subarachnoid hemorrhage. This study aimed to characterize the impact of recent amphetamine use on vasospasm development in aneurysmal subarachnoid hemorrhage as well as neurological outcomes.

Methods: We retrospectively screened 441 consecutive patients admitted with a diagnosis of subarachnoid hemorrhage who underwent at least one cerebral digital subtraction angiogram.

Sole-Solvent High-Entropy Electrolyte Realizes Wide-Temperature and High-Voltage Practical Anode-Free Sodium Pouch Cells.

Anode-free sodium batteries (AFSBs) hold great promise for high-density energy storage. However, high-voltage AFSBs, especially those can stably cycle at a wide temperature range are challenging due to the poor electrolyte compatibility toward both the cathode and anode. Herein, high-voltage AFSBs with cycling ability in a wide temperature range (-20-60 °C) are realized for the first time via a sole-solvent high-entropy electrolyte based on the diethylene glycol dibutyl ether solvent (D2) and NaPF salt.

Systemic vasculitis with latent tuberculosis infection and associated factors: a cross-sectional multicenter study.

Objectives: Systemic vasculitis patients are at a higher risk of developing latent tuberculosis infection (LTBI). However, there is currently no literature elucidating the positivity rate and risk factors for LTBI in systemic vasculitis patients.

Methods: Our study is a multi-center, cross-sectional study that enrolled systemic vasculitis patients from 13 comprehensive hospitals in China.
