The practical application of formic acid for large-scale hydrogen storage is constrained by its low H production rates. Conventional strategies rely on excessive chemical additives to accelerate the initial deprotonation step for efficient dehydrogenation. However, this approach is energy-consuming and compromises the intrinsic hydrogen storage density (53 g L) of formic acid.

Porous metal-organic polyhedra (MOPs) have strong covalent and coordinate bonds that define the intrinsic pore of the cage. The intermolecular interactions between cages tend to be weaker, such that they rearrange during the solvent exchange process preceding gas sorption measurements. The reduction in crystal size that this often causes limits the availability of structural data that could enable understanding of observed gas uptake.

They oxidise methane in anoxic niches by transferring electrons to nitrate, metal oxides, or sulfate-reducing bacteria. No ANMEs have been isolated, hampering the biochemical investigation of anaerobic methane oxidation.

Effectively evaluating and promoting pro-grazing practices necessitates the implementation of a verification system. To address this imperative, exploration of milk composition analysis as a means to assess grazing practices has garnered substantial attention. In this study, we used component predictions from milk Fourier-transform mid-infrared (FT-MIR) spectra to construct an indicator to estimate the proportion of herbage consumed by dairy cows and another indicator to validate grazing.

Aminoglycosides (AGs) are broad-spectrum antibiotics effective against Gram-negative bacteria, with uptake dependent on membrane potential. However, the mechanisms of AG entry remain incompletely understood. Here, we identify a previously undescribed uptake pathway via carbohydrate transporters in .
