Vacancy-Activated B-Doping for Efficient 2e- Oxygen Reduction through Suppressing H2O2 Decomposition at High Overpotential.

The production of hydrogen peroxide (H2O2) through two-electron oxygen reduction reaction (2e- ORR) has emerged as a more environmentally friendly alternative to the traditional anthraquinone method. Although oxidized carbon catalysts have intensive developed due to their high selectivity and activity, the yield and conversion rate of H2O2 under high overpotential still limited. The produced H2O2 was rapidly consumed by the increased intensity of H2O2 reduction, which could ascribe to decomposition of peroxide radicals under high voltage in the carbon catalyst.

Impact of thrombocytopenia on failure of endoscopic variceal treatment in cirrhotic patients with acute variceal bleeding.

Background: Acute variceal bleeding (AVB), a life-threatening complication of liver cirrhosis, can be effectively treated by endoscopy, but there is a risk of early rebleeding after endoscopic variceal treatment (EVT). Thrombocytopenia is the most common hemostatic abnormality in liver cirrhosis. However, it is still unclear about whether thrombocytopenia increases the failure of EVT in cirrhotic patients with AVB.

In vitro metabolism of seven arolyl-derived fentanyl-type new psychoactive substances.

Over the past decade, fentanyl-type new psychoactive substances (F-NPS) have emerged as the most representative synthetic opioids in third-generation drugs. These substances are characterized by their "low" fatal dose and parent drug levels in biological matrices, "fast" rates of derivatization and metabolism, and "many" derivatization sites and analogs. The low levels of parent fentanyl NPS in biological matrices complicate their detection, necessitating the use of characteristic metabolites as biomarkers for forensic analysis.

Introduction: Emotion recognition using electroencephalography (EEG) is a key aspect of brain-computer interface research. Achieving precision requires effectively extracting and integrating both spatial and temporal features. However, many studies focus on a single dimension, neglecting the interplay and complementarity of multi-feature information, and the importance of fully integrating spatial and temporal dynamics to enhance performance.

Scintillating Glass Fiber Arrays Enable Remote Radiation Detection and Pixelated Imaging.

The emerging metal halide perovskites are challenging the traditional scintillators in the field of radiation detection and radiography. However, they lack the capability for remote and real-time radiation monitoring and imaging in confined and hostile conditions. To address this issue, details on an inorganic scintillating glass fiber incorporating perovskite quantum dots (QDs) as highly efficient pixelated radiation emitters are reported, while the glass fibers themselves serve at the same time as low-loss waveguides, enabling long-distance and underwater X-ray detection.
