Summary: In this study, the cleaning effect of three complexing agents, glycine, EDTA, and TAD, on ceria particles on the polished silicon dioxide surface were investigated. The results showed that EDTA, at a concentration of 0.15 wt% and pH 11, can remove 99% of ceria particles from the substrate. The proposed removal mechanism involves the undercutting effect of carboxyl functional groups, breaking the Ce-O-Si chemical connection and enhancing the electrostatic repulsion force between the CeO2 and SiO2 substrate.

Summary: A series of alumina slurries were prepared using complexing agents with different numbers of carboxyl groups, which effectively increased the absolute value of alumina particles' zeta potential and enhanced their dispersibility. Chemical mechanical polishing (CMP) was performed on sapphire substrates using the slurries with complexing agents, and the material removal rate initially increased and then declined as the carboxyl group count rose. The addition of disodium ethylenediaminetetraacetic acid with four carboxyl groups in alumina slurry resulted in a 52% higher material removal rate of about 4.0 mu m/h compared to without complexing agents, and a 51% lower average surface roughness of 0.96 nm. The complexing agents reacted with the abrasive particles and sapphire substrates, and the slurries demonstrated excellent wettability and mechanical action, resulting in a smoother sapphire surface through the synergy of chemical etching and mechanical removal.

Summary: This study investigated the passivation mechanism of three azole inhibitors on cobalt, with 1-H carboxyl benzotriazole (CBT) showing the strongest passivation effect. Analysis suggested that the carboxyl group on CBT played a crucial role in preventing cobalt oxidation. Furthermore, the presence of methyl on 5-methyl-benzotriazole (TTA) led to better passivation effect compared to benzotriazole (BTA).

Summary: In this study, a facile complexing agent-assistant photodeposition strategy was introduced to construct highly efficient SA Ag-N(3)S(1) asymmetric site catalyst. The construction of SA site is achieved through heteroatom doping on the substrate and complexation of coexisting amine ligands with silver cation. The modulation of electronic structure states greatly enhances the photocatalytic hydrogen production ability of the Ag-N3S1 site-decorated carbon nitride. This exploration provides a promising universal strategy for the establishment of high-efficiency SA catalysts in broader fields.

Summary: The demand for higher energy density and safety has led to the replacement of conventional Li+ batteries with all-solid-state lithium-ion batteries (ASSLIB). Sulfide solid-state electrolytes (SSEs) with high Li+ conductivity have demonstrated potential for commercialization of ASSLIBs. However, issues such as SSE decomposition at electrodes/electrolyte interfaces and Li-dendrite growth at anodes hinder the commercialization of ASSLIBs.
