Here we report a facile method for the synthesis of nickel oxide-nickel (NiO@Ni) Mott-Schottky catalyst employing metalorganic framework (MOF) as the precursor. A direct amidation protocol of aldehydes with amines has been optimized under mild conditions using NiO@Ni Mott-Schottky catalyst and it shows far better catalytic activity than the NiOÀ Ni nanoparticles prepared from simple Ni 2 + salt under similar reaction conditions. The heterogeneous catalyst is robust, recyclable and efficient to provide comparable yield to costly ligand-based homogeneous Ni catalysts. The scope of the reaction protocol has been explored with variably substituted substrates. The reaction initiates by homolytic cleavage of peroxide and proceeds through radical mechanism.

This paper proposes a framework for generating sizing function in meshing assemblies. Size control is crucial in obtaining a high-quality mesh with a reduced number of elements, which decreases computational time and memory use duringm eshg eneration and analysis. This proposed framework is capable of generating a sizing function based on geometric and non-geometric factors that influence mesh size. The framework consists of a background octree grid for storing the sizing function,a set of source entities for providings izing information based on geometric and non-geometric factors, and an interpolation module for calculatingthe sizing on the background octree grid using the source entities. Source entities are generated by performing a detailed systematic study to identify all the geometric factors of ana ssembly. Disconnected skeletons are extracted and used as tools to measure 3D-proximity and 2D-proximity, which are two of the geometric factors. Non-geometric factorss ucha s user-defined size and pre-meshed entities that influence size are also addressed. The framework is effective ing enerating a variety ofm eshes of industrym odels with less computational cost.

Herein, we have demonstrated Lewis acid Fe(III)-assisted hydroxylation of ZIF-67 to form FexCo-layered double hydroxide (LDH) nanosheets. The catalyst Fe0.4Co-LDH produced an excellent water oxidation activity to reach a current...
