In this paper, the chemical adsorption behavior of malathion on silver nanosubstrates is studied by surface-enhanced Raman scattering technology (SERS) and density functional theory (DFT). Based on the concepts of density functional theory (DFT) and hard–soft acid–base (HSAB) theory, the interaction between malathion and Ag was discussed by combining SERS. Four adsorption conformations were confirmed

The interface between metal supports plays a crucial role in many multiphase catalytic processes and has received widespread attention, but research on interface interactions under external electric fields is still far from sufficient. In this paper, the activation of CO2 on the surface and interface of catalyst model Nin/Al2O3(n = 1–7,9) under positive electric field (+0.6 V/Å), zero electric field

Polybetaine nanobrushes are widely used as inert platforms for label-free biosensing due to their resistance to nonspecific interactions. Despite being considered cationic or electrically neutral, polybetaines can exhibit a negative zeta potential (ZP) at pHs above their isoelectric point (pI). To clarify whether negative zeta potential effectively contributes to surface interactions, we examined three

Chlorite is a common gangue mineral in primary rutile ores, which poses challenges for selective flotation. This study evaluates the depression performance of sodium fluosilicate (SSF), carboxymethyl cellulose (CMC), and their combination (CMC+SSF) in a benzohydroxamic acid flotation system. Pure mineral flotation tests demonstrate that the individual depressants exhibit limited selectivity, whereas

The issue of environmental contamination is becoming increasingly critical as industrial and agricultural activities continue to grow. As a result, there is a growing need for fast and accurate methods to detect and determine pesticide residues in environmental samples. This study highlights the development of nature-inspired 1D Bi2S3 vertically oriented nanorods on fluorine-doped tin oxide glass
