Ice plant (Mesembryanthemum crystallinum L.) is a halophyte and an inducible CAM plant. Ice plant seedlings display moderate salt tolerance, with root growth unaffected by 200 mM NaCl treatments, though hypocotyl elongation is hindered in salt-stressed etiolated seedlings.

Volatile sulfur compounds (VSCs) are prevalent human biogases detectable in individuals with periodontal disease; therefore, measuring VSC gases in human breath can yield significant, noninvasive diagnostic information indicative of such diseases. In this study, we developed a gas sensor with selective and enhanced sensing capabilities for VSCs methyl mercaptan and hydrogen sulfide. This sensor comprises a cellulose paper substrate impregnated with 2,2'-dithiobis(5-nitropyridine) and sodium acetate.

Hydrogen evolution reaction and Zn dendrite growth, originating from high water activity and the adverse competition between the electrochemical kinetics and mass transfer, are the main constraints for the commercial applications of the aqueous zinc-based batteries. Herein, a weak H-bond interface with a suspension electrolyte is developed by adding TiO nanoparticles into the electrolytes. Owing to the strong polarity of Ti-O bonds in TiO, abundant hydroxyl functional groups are formed between the TiO active surface and aqueous environment, which can produce a weak H-bond interface by disrupting the initial H-bond networks between the water molecules, thereby accelerating the mass transfer of Zn and reducing the water activity.

In recent years, antimicrobial peptides (AMPs) have emerged as a potent weapon against the growing threat of antibiotic resistance. Among AMPs, the ones containing tryptophan (W) and arginine (R) exhibit enhanced antimicrobial properties, benefiting from the unique physicochemical features of the two amino acids. Herein, we designed three hexapeptides, including WR, DWR (D-isomer), and RF, derived from the original sequence, RWWRWW-NH2 (RW).

The thermocatalytic hydrogenation of CO2 to ethanol has attracted significant interest because ethanol offers ease of transport and substantial value in chemical synthesis. Here, we present a state-of-the-art catalyst for the CO2 hydrogenation to ethanol achieved by precisely depositing single-atom Ir species on P cluster islands situated on the In2O3 nanosheets. The Ir1-Px/In2O3 catalyst achieves an impressive ethanol yield of 3.
