WebSnSe2 is an anisotropic binary-layered material with rich physics, which could see it used for a variety of potential applications. Here, we investigate the gas-sensing properties of SnSe2 using first-principles calculations and verify predictions using a gas sensor made of few-layer SnSe2 grown by chemical vapor deposition. Theoretical simulations indicate that … Web20 de jan. de 2024 · It turns out that Pt 1 /CeO 2 is indeed a highly active and selective catalyst for a broad range of nitroarenes: Almost all of the selectivity to the corresponding amine was higher than 95%, and the TOFs varied from 20 to about 200 h −1.

Web18 de fev. de 2024 · To achieve high etching selectivity of molybdenum in relation to photoresist, it is necessary to reduce the influence of the physical component of the process, that is the ion bombardment. For this purpose, it was decided to minimize the bias voltage and to maintain it at − 10 V in all experiments. Web18 de jan. de 2024 · Thus, a better statement of this goal is to predict high selectivity values far beyond the bounds of what is encompassed in the training data. Herein, … Web1 de ago. de 2024 · Higher Education (HE) selectivity, often called college selectivity in the US, refers to the quality of the students that attend each Higher Education Institution (HEI). HE selectivity is typically measured by the average ability of students on a course, as measured by their mean Standard Aptitude Test (SAT) score in the US, or “A ... poorly timed photos
