We report on the temperature dependence of the ZrTe(5) electronic properties, studied at equilibrium and out of equilibrium, by means of time and angle resolved photoelectron spectroscopy. Our results unveil the dependence of the electronic band structure across the Fermi energy on the sample temperature. This finding is regarded as the dominant mechanism responsible for the anomalous resistivity observed at T*∼160 K along with the change of the charge carrier character from holelike to electronlike. Having addressed these long-lasting questions, we prove the possibility to control, at the ultrashort time scale, both the binding energy and the quasiparticle lifetime of the valence band. These experimental evidences pave the way for optically controlling the thermoelectric and magnetoelectric transport properties of ZrTe(5).

The detection of exons is an important area of research in genomic sequence analysis. Many signal-processing methods have been established successfully for detecting the exons based on their periodicity property. However, some improvement is still required to increase the identification accuracy of exons.

Wearable temperature-sensitive electronic skin enables robots to rapidly detect environmental changes and respond intelligently, thereby reducing temperature-related mechanical failures. Additionally, this temperature-sensitive skin can measure and record the temperature of external objects, broadening its potential applications in the medical field. In this study, we designed a thermally sensitive artificial ionic skin using ionic liquids (ILs) as solvents and carbon nanotubes (CNTs) as thermally conductive fillers.

This study presents the design, synthesis, and evaluation of a novel series of coumarin-based compounds (9a-t) as potential anticancer agents. The compounds were strategically designed to inhibit cancer-related carbonic anhydrase (CA) isoforms IX and XII and tubulin polymerization. Two approaches were employed for CA inhibition: utilizing the coumarin motif to occlude the CA active site entrance and incorporating zinc-binding groups (sulfonamide, carboxylic acid, and thiol) to interact with the catalytic zinc ion.

Small-molecule pectin (SMP) extracted from the leaves of Premna ligustroides Hemsl, with a molecular weight range of 5000-35,000 Da, has demonstrated anti-inflammatory and lipid-lowering properties in vitro. This study explored the effects of SMP on hypercholesterolemia in mice, with a focus on inflammation, lipid profiles, and cholesterol metabolism. Mice received SMP at doses of 607, 303, and 152 mg/kg body weight.

In order to improve the preservation of red grape fruits, 'Chuju' polysaccharides (CCP) were cross-linked with chitosan (CS) to create CCP/CS composites with varying ratios. These composites were comprehensively characterized using FT-IR, C NMR, and SEM, which confirmed a smooth film surface and a uniform distribution of CCP. The composite films demonstrated efficacy in maintaining the quality of red grapes by mitigating shriveling and significantly reducing firmness loss by 22.
