The potential range of the transition region between the diffusion-limited reduction to oxidation of hydrogen peroxide depends strongly on the nature of the cation of the supporting alkaline electrolyte. Non-covalent interactions between the hydrated alkali metal cations and chemisorbed OH species on platinum influence the potential-dependent reaction kinetics.

Cannulae are tubular protein filaments that accumulate on the extracellular surface of the hyperthermophilic archaeon during cell division. Cannulae have been postulated to act as a primitive extracellular matrix through which cells could communicate or exchange material, although their native biological function remains obscure. Here, we report cryoEM structural analyses of cannulae and of protein assemblies derived from recombinant cannula-like proteins.

Utilizing cellulose nanocrystals (CNCs) to mimic biological skin capable of converting external stimuli into optical and electrical signals represents a significant advancement in the development of advanced photonic materials. However, traditional CNC photonic materials typically exhibit static and singular optical properties, with their structural color and mechanical performance being susceptible to water molecules, thereby limiting their practical applications. In this study, CNC-based conductive elastomers with dynamic mechanochromism, fluorescence responsiveness, and enhanced water resistance were developed by incorporating carbon quantum dots (C QDs) and hydrophobic deep eutectic solvents (HDES) into CNC photonic films via an in-situ swelling-photopolymerization method.

The polyphenol-starch complex has become a hot research topic since it is evident that this modification method can alter the physicochemical properties of starch as well as improve its nutritional value. This work aimed to evaluate the effect of ginger polyphenol gingerols (GNs) and shogaols (SNs) on the structure of starch with different amylose content (WCS, CS, G56, G80). Textural and rheological results indicated that GNs and SNs had more pronounced inhibitory retrogradation effects for relative low-level amylose starches (WCS and CS) compared to relative high-level amylose starches (G56 and G80).

BMP-9 and BMP-10 are TGF-β family signaling ligands naturally secreted into blood. They act on endothelial cells and are required for proper development and maintenance of the vasculature. In hereditary hemorrhagic telangiectasia, regulation is disrupted due to mutations in the BMP-9/10 pathway, namely in the type I receptor ALK1 or the co-receptor endoglin.
