Lactose intolerance is a pathology caused by lactase enzyme deficiency, usually produced in the intestinal cells provoking symptoms as abdominal pain, bloating, diarrhea, gas and nausea. Gaxilose, 4-O-β-D galactopyranosyl-d-xylose, is used as a diagnostic drug for a non-invasive method for hypolactasia diagnosis. To date, no definitive guide for identifying gaxilose and distinguishing between crystalline forms is available. Data have been collected from a number of different analytical techniques in order to provide a full characterization of the compound and a simple method to discriminate between two solid forms.

The objective of this study was to investigate the effect of β-glucan on the pasting, gelling, rheological properties, and multi-level structures of the highland barley (HB) starch after dynamic high pressure microfluidization (DHPM) treatment, exploring the inhibition mechanisms of starch retrogradation by endogenous β-glucan after DHPM. DHPM treatment led to a decrease in the viscosity (K values from 161.1 to 54.

Ultrathin indium oxide films show great potential as channel materials of complementary metal oxide semiconductor back-end-of-line transistors due to their high carrier mobility, smooth surface, and low leakage current. However, it has severe thermal stability problems (unstable and negative threshold voltage shifts at high temperatures). In this paper, we clarified how the improved crystallinity of indium oxide by using ultrahigh-temperature rapid thermal O annealing could reduce donor-like defects and suppress thermal-induced defects, drastically enhancing thermal stability.

Polymer composite materials encounter considerable challenges in sustaining superior tribological properties at high rotational speeds. Inspired by the microstructure of dragonfly wings, a novel thermally stable and ambient pressure curing poly(urea-imide) resin (PURI) with excellent tribological properties has been eco-friendly synthesis using bio-based greener solvents. Furthermore, The PURI composites enhanced with polyether ether ketone (PEEK) and Polytetrafluoroethylene (PTFE) blended fabrics demonstrate excellent mechanical, with tensile strengths exceeding 175 MPa.

This study reveals the capability of nanostructured organic materials to undergo pseudomorphic transformations, a ubiquitous phenomenon occurring in the mineral kingdom that involves the replacement of a mineral phase with a new one while retaining the original shape and volume. Specifically, it is demonstrated that the postoxidation process induced by HOF·CHCN on preformed thiophene-based 1D nanostructures preserves their macro/microscopic morphology while remarkably altering their electro-optical properties by forming a new oxygenated phase. Experimental evidence proves that this transformation proceeds via an interface-coupled dissolution-precipitation mechanism, leading to the growth of a porous oxidized shell that varies in thickness with exposure time, enveloping the pristine smooth core.

Self-powered broadband photodetectors (SPBPDs) hold great potential for next-generation optoelectronic applications, but their performance is often limited by interface defects that impair charge transport and increase recombination losses. In this work, we report the enhancement of the photodetection efficiency of SPBPDs by partially substituting copper (Cu) with silver (Ag) in kesterite CuZnSnS (ACZTS) thin films. Varying Ag concentrations (0%, 2%, 4%, 6%) are incorporated into the CZTS layer, forming a TiO/ACZTS heterojunction in superstrate configuration fabricated via a low-cost sol-gel spin-coating technique with low-temperature open air annealing avoiding conventional postdeposition sulfurization or selenization.
