Summary: In this study, we investigated chemical sensing using surface-enhanced Raman scattering with gold nanocolumn templates. The glancing angle deposition with magnetron sputtering technique was chosen for its low-cost production and ease of implementation. The fabricated gold nanocolumnar structures allowed for the production of a high density of strongly confined electric field spots. The vertical and tilted nanocolumnar templates showed promising results for the detection and adsorption of thiophenol molecules.

Summary: A highly fluorescent, sensitive, and selective fluorometric assay for detecting Hg2+ ions was developed using vancomycin functionalized and polyethyleneimine stabilized gold nanoparticles (PEI-f-AuNPs@Van). The gold nanoparticles exhibited strong fluorescence properties with excitation and emission wavelengths of 320 nm and 418 nm, respectively. The detection limit for Hg2+ ion was determined to be 0.988 nM within a linear range, while in natural environmental samples it was 12.5 nM. The designed probe showed high selectivity for mercury (II) cations among other divalent cations.

Summary: Plasmonic nanoparticles in dimer format are used for single molecule sensing, where the interaction with hairpin DNA leads to a shift in localized surface plasmon resonance. Spectroscopy may detect this shift, but point-of-care devices require a faster analysis method. By using dark-field imaging and digital analysis, the plasmonic resonance shift of thousands of dimer structures can be measured in minutes. The challenge is separating dimers from non-specifically bound clusters to achieve accurate results. The LAB-based classifier algorithm demonstrated the highest accuracy for this digital separation.

Summary: In this study, a mixed-linker conductive MOF system was developed by incorporating tetrathiafulvalene and Ni-bis(dithiolene) moieties, allowing precise control over electronic structures and semiconductor characteristics by adjusting their molar ratio. The semiconducting behavior of the MOF system can be switched from n-type to p-type by increasing the ratio of tetrathiafulvalene to Ni-bis(dithiolene), resulting in a three orders of magnitude increase in electrical conductivity. Additionally, the mixed-linker MOFs showed synergistic and nonlinear modulation effects on the chemiresistive detection of VOCs, with sensing performance modulated by the linker ratios.

Summary: Nitrate-containing industrial wastewater is a serious threat to global food security and public health safety. Electrocatalytic nitrate reduction offers better sustainability compared to traditional microbial denitrification, with ultra-high energy efficiency and the production of high-value ammonia (NH3). However, the acidic nature of most industrial nitrate-containing wastewater contradicts the working conditions of denitrifying bacteria and inorganic electrocatalysts, demanding pre-neutralization and leading to competition and dissolution issues.

Summary: Replacing the oxygen evolution reaction (OER) with water-assisted oxidation of organic molecules is a promising approach for sustainable electrochemical biomass utilization. In this study, spinel sulfides were investigated for the electrooxidation of furfural and 5-hydroxymethylfurfural, showing superior catalytic performance compared to spinel oxides. The phase transition of spinel sulfides into amorphous bimetallic oxyhydroxides during electrochemical activation was found to be responsible for their excellent conversion rate, selectivity, faradaic efficiency, and stability. A volcano-like correlation was also established between their BEOR and OER activities.
