Electronic structure of superconducting infinite-layer lanthanum nickelates.

Revealing the momentum-resolved electronic structure of infinite-layer nickelates is essential for understanding this class of unconventional superconductors but has been hindered by the formidable challenges in improving the sample quality. In this work, we report the angle-resolved photoemission spectroscopy of superconducting LaSrNiO films prepared by molecular beam epitaxy and in situ atomic-hydrogen reduction. The measured Fermi topology closely matches theoretical calculations, showing a large Ni [Formula: see text]-derived Fermi sheet that evolves from hole-like to electron-like along and a three-dimensional (3D) electron pocket centered at the Brillouin zone corner.

Comprehensive Chlorine Suppression: Advances in Materials and System Technologies for Direct Seawater Electrolysis.

Seawater electrolysis offers a promising pathway to generate green hydrogen, which is crucial for the net-zero emission targets. Indirect seawater electrolysis is severely limited by high energy demands and system complexity, while the direct seawater electrolysis bypasses pre-treatment, offering a simpler and more cost-effective solution. However, the chlorine evolution reaction and impurities in the seawater lead to severe corrosion and hinder electrolysis's efficiency.

Genetic analysis of a pedigree with hereditary coagulation factor XII deficiency.

Analyze the clinical phenotype and gene mutations of a family with hereditary FXII deficiency, and preliminarily explore its phenotypic manifestations. The routine coagulation indicators and related coagulation factors were measured.Thromboelastography and thrombin generation tests simulated coagulation and anticoagulation states in vitro and in vivo.

Retina-Inspired Flexible Visual Synaptic Device for Dynamic Image Processing.

Exploiting biomimetic perception of invisible spectra in flexible artificial human vision systems (HVSs) is crucial for real-time dynamic information processing. Nevertheless, the fast processing of motion objects in natural environments poses a challenge, necessitating that these artificial HVSs simultaneously have swift photoresponse and nonvolatile memory. Here, inspired by the human retina, we propose a flexible UV neuromorphic visual synaptic device (NeuVSD) based on GaO@GaN-composited nanowires for dynamic visual perception.

The Impact of Hematologic Disorders on the Severity of Cerebral Venous Sinus Thrombosis: A Comparative Study.

Hematologic diseases are considered important contributors to cerebral venous sinus thrombosis (CVST) cases. This retrospective study aims to compare the difference of the clinical and radiological characters between CVST patients with and without hematologic diseases. Consecutive hospitalized CVST patients with hematologic disorders constituted the hematologic disorder group, while that without identifiable risk factors comprised the control group in this study.
