Metal nanoclusters (NCs) are a special class of nanoparticles composed of a precise number of metal atoms and ligands. Because the proportion of ligands to metal atoms is high in metal NCs, the ligand type determines the physical properties of metal NCs. Furthermore, ligands presumably govern the entire formation process of the metal NCs. However,...

Solid‐state electrolyte batteries have attracted significant interest as promising next‐generation batteries due to their achievable high energy densities and nonflammability. In particular, curable polymer network gel electrolytes exhibit superior ion conductivity and interfacial adhesion with electrodes compared to oxide or sulfide solid electrol...

Metal nanoclusters (NCs), an important class of nanoparticles (NPs), are extremely small in size and possess quasi-molecular properties. Due to accurate stoichiometry of constituent atoms and ligands, NCs have strong structure-property relationship. The synthesis of NCs is seemingly similar to that of NPs as both are formed by colloidal phase trans...

The location and distribution of aluminum in zeolites is considered important in determining various properties, such as acidity and reactivity. Controlling the placement of aluminum substitution has therefore been of significant interest, and a number of studies have been conducted, including synthesis methods using either different organic struct...

... However, NMCs are usually highly reactive, so it is standard to use capping agents to stabilize them [6]. Thus, the precise determination of the structure of coordinate complexes with ligands remains challenging despite advances in theoretical and experimental methods [7][8][9]. ...
... The role of anionic vacancies in another La-Sr-Co perovskite composite obtained from green mechanical milling was proven by Luo et al. for the degradation of doxycycline [88]. A few recent examples of mechanochemically prepared materials are steam reforming of acetic acid over mesoporous Ni-Al 2 O 3 for H 2 production [89], localization of vanadia on TiO 2 for NH 3 -SCR at low temperature [90], CH 4 decomposition over NiO-MgO, [91], etc. Moreover, mechanochemically synthesized perovskites showed notable activity in optoelectronic applications [92]. ...
... The issue of controlling Al siting in zeolites is a very complex and unresolved one [39][40][41][42][43][44][45][46][47][48][49][50][51][52][53][54][55][56]. It is universally accepted that the measure of the number of Al pairs in zeolitic materials can be determined by Co(II) ion exchange capacity [38,[57][58][59][60][61]. ...
