Quasi-2D DJ type perovskites theoretically offer excellent properties for X-ray detection, but they often face issues such as phase segregation and small crystal size. In this study, we synthesized large single crystals of quasi-2D DJ type perovskite (3AMPY)(MA)PbBr using temperature-controlled crystallization. The resulting X-ray detector exhibited high resistivity (1.

The regulation of the valleytronic properties of two-dimensional materials can contribute to the in-depth study of valley physics and improve its potential for applications in valleytronic devices. Herein, we systematically investigate the electronic properties and the modulation of the valleytronic properties in single-layer NbSeCl. Our results reveal that NbSeCl is a semiconductor with a 105.

Background: Automatic sleep staging is essential for assessing sleep quality and diagnosing sleep disorders. While previous research has achieved high classification performance, most current sleep staging networks have only been validated in healthy populations, ignoring the impact of Obstructive Sleep Apnea (OSA) on sleep stage classification. In addition, it remains challenging to effectively improve the fine-grained detection of polysomnography (PSG) and capture multi-scale transitions between sleep stages.

The transfer of large-area, continuous, chemical vapor deposition (CVD)-grown graphene without introducing defects remains a challenge for fabricating graphene-based electronics. Polymer thin films are commonly used as supports for transferring graphene, but they typically require thermal annealing before transfer. However, little work has been done to thoroughly investigate how thermal annealing affects the polymer/graphene thin film when directly annealed on the growth substrate.

In silico computational methods have been widely utilized to study enzyme catalytic mechanisms and design enzyme performance, including molecular docking, molecular dynamics, quantum mechanics, and multiscale QM/MM approaches. However, the manual operation associated with these methods poses challenges for simulating enzymes and enzyme variants in a high-throughput manner. We developed the NAC4ED, a high-throughput enzyme mutagenesis computational platform based on the "near-attack conformation" design strategy for enzyme catalysis substrates.
