Summary: Increasing the alkali metal cation concentration enhances the activity of the hydrogen evolution reaction on gold electrodes, while increasing the electrolyte pH indirectly affects the reaction activity by tuning the near-surface cation concentration. However, too high near-surface cation concentration can lead to a decrease in the reaction activity due to surface blockage.

Summary: In this study, disordered Au nanoclusters anchored on two-dimensional ultrathin Ti3C2Tx MXene nanosheets are explored as highly active and selective electrocatalysts for efficient N-2-to-NH3 conversion. A combination of in situ near-ambient pressure X-ray photoelectron spectroscopy and operando X-ray absorption fine structure spectroscopy is employed to unveil the uniqueness of this catalyst for N2RR. The disordered structure is found to serve as the active site for N-2 chemisorption and activation during the N2RR process.

Summary: Electrochemical nitrate (NO3-) reduction to ammonia (NH3) is a promising approach for recovering NO3- pollutants and sustainable NH3 production. However, the efficiency is limited by complex reaction processes and hydrogen precipitation. This study demonstrates high performance nitrate reduction reaction on self-supported Pd nanorod arrays in porous nickel framework foam, achieving a significant NH3 yield rate and stability. Large-area Pd/NF electrode also shows potential for industrial application. The enrichment effect of Pd nanorods promotes H species adsorption for ammonia synthesis.

Summary: Gold nanorod dimers bridged by double-stranded DNA exhibit variable chiral configurations depending on the chemical and ionic properties of the solvent medium. The chiral behavior is governed by the twist-stretch coupling of the DNA and intermolecular interactions between nanorods. Changes in depletant or ion concentration of the solvent medium can lead to different classes of configurational responses by the dimers, including chirality-switching behavior.

Summary: Sonodynamic therapy (SDT), an innovative treatment strategy, utilizes low-intensity ultrasound radiation combined with a sonosensitizer to overcome solid tumors. In this study, selenium-polyethylene glycol-curcumin nanoparticles (Se-PEG-Cur NPs) were synthesized and characterized as a new sonosensitizer capable of absorbing ultrasonic waves. The cytotoxicity of Se-PEG-Cur NPs was compared to gemcitabine (GEM) in pancreatic cancer treatment, and the results showed that the combination of Se-PEG-Cur NPs and GEM, along with ultrasound radiation, induced apoptosis in cancer cells. Se-PEG-Cur NPs demonstrated potential as an efficient sonosensitizer for SDT treatment of pancreatic cancer.
