3 de abr. de 2017 · Herein, a novel rhodium (I)-catalyzed tandem reaction of readily accessible azides with isonitriles and boronic acids via a carbodiimide intermediate is achieved. This protocol offers an alternative approach toward N-sulfonyl-, N-acyl-, and N- phosphoryl-functionalized, as well as general N-aryl and N-alkyl amidines with broad substrate scope.
6 de mar. de 2020 · These properties also make PSCs attractive as top cells for tandem applications that use lower band gap bottom cells such as crystalline silicon (c-Si) and copper indium gallium selenide (CIGS) (7–18).By reducing thermalization losses, stacking PV absorbers of decreasing band gap in a multijunction device can overcome the Shockley-Queisser efficiency limit of 33.7% for single-junction solar ...
16 de may. de 2022 · Pyroptosis is a lytic and inflammatory type of programmed cell death that is usually triggered by inflammasomes and executed by gasdermin proteins. The main characteristics of pyroptosis are cell swelling, membrane perforation, and the release of cell contents. In normal physiology, pyroptosis plays a critical role in host defense against ...
14 de dic. de 2016 · Here we report an anomalously structured Ru catalyst that shows 2.5 times higher hydrogen generation rate than Pt and is among the most active HER electrocatalysts yet reported in alkaline solutions. The identification of new face-centered cubic crystallographic structure of Ru nanoparticles was investigated by high-resolution transmission ...
Human angiostrongyliasis caused by Angiostrongylus cantonensis, a rat lungworm, has been reported globally. Human infections are acquired by ingestion of raw or undercooked snails or slugs, paratenic hosts such as prawns, or contaminated vegetables that contain the infective larvae of the worm. So far, at least 2827 cases of the disease have ...
21 de feb. de 2017 · Organometallic complexes with metal–nitrogen/carbon (M–N/C) coordination are the most important alternatives to precious metal catalysts for oxygen reduction and evolution reactions (ORR and OER) in energy conversion devices. Here, we designed and developed a range of molecule-level graphitic carbon nitride (g-C3N4) coordinated transition metals (M–C3N4) as a new generation of M–N/C ...
22 de may. de 2023 · This paper presents an exhaustive quantitative and qualitative evaluation of Large Language Models (LLMs) for Knowledge Graph (KG) construction and reasoning. We engage in experiments across eight diverse datasets, focusing on four representative tasks encompassing entity and relation extraction, event extraction, link prediction, and question-answering, thereby thoroughly exploring LLMs ...
