Weak Decays of First Radial Excited D _q (2 S ) and B _q (2 S ) States

Abstract

We study the exclusive semileptonic and nonleptonic decays of the first radial excited heavy-light pseudoscalars 𝐷𝑞(2𝑆) and 𝐵𝑞(2𝑆) (𝑞 = 𝑢, 𝑑, 𝑠) with the improved Bethe-Salpeter (B-S) method which takes into account the relativistic effects in wave functions and transition matrix elements.

XPS study of the surface properties and Ni particle size determination of Ni‐supported catalysts

“…In the literature, it has been reported that the addition of Ce increases Ni dispersion. [27,28] However, the surface atomic concentration for the catalyst presented in this work shows a decrease of about 60% for Cecontaining catalysts and 10% for Pr ones. Besides, the metallic dispersion for the Ce-containing catalysts increases or remains constant after reduction, whereas those with Pr decrease.…”

Non‐Mercury Catalytic Acetylene Hydration over Bimetallic Cu–Zn Catalysts for Acetaldehyde Production in Gas‐Liquid System

“…Many studies have reported that the addition of a second metal (even if it is inactive by itself) can significantly improve the activity and selectivity of a reaction by enhancing the stability of the catalyst through the synergistic effect of two metals. [25][26][27][28] Bimetallic catalysis has great potential for developing versatile reaction conditions [29][30] and studies on bimetallic catalytic reactions have attracted more attention over the past few decades. [31][32] Recently, many research groups reported that bimetallic catalyst benefits the carbonylation of organics, [30,[33][34] leading us to consider that a bimetallic catalyst can also promote acetylene hydration.…”

Hierarchical 3D TiO2 Nanotube Arrays Sensitized by Graphene Oxide and ZnxCdyS for High Performance Photoelectrochemical Applications

“…As possible next-generation sensitizers, semiconductors have many advantages such as facile tunability of effective band gaps, high stability and inertness toward atmospheric oxygen and water, and possibilities of using the materials to construct novel structures such as multilayered-sensitizers or hybrid-sensitizers. [20] Until now, some deposition techniques have been developed to prepare the compound film, such as chemical vapor deposition, [21] electrodeposition, [22] chemical bath deposition, [23] and atomic layer deposition. [24,25] Among them, chemical bath deposition is a simpler method and less expensive than other compound film deposition techniques.…”
