Unraveling the infrared detection properties of BiTe depending on thickness under the semiconductor and metal surface states.

BiTe recently emerges as a promising candidate material for the next generation of mid-wave to long-wave infrared photodetection owing to its exceptionally narrow bandgap (approximately 0.2 eV) and the favorable photoelectronic properties. In particular, its topological insulator structure is safeguarded by time-reversal symmetry, leading to electronic structures with distinct surface and bulk states as well as distinctive optoelectronic properties.

Protein evolution has shaped enzymes that maintain stability and function across diverse thermal environments. While sequence variation, thermal stability and conformational dynamics are known to influence an enzyme's thermal adaptation, how these factors collectively govern stability and function across diverse temperatures remains unresolved. Cytosolic malate dehydrogenase (cMDH), a citric acid cycle enzyme, is an ideal model for studying these mechanisms due to its temperature-sensitive flexibility and broad presence in species from diverse thermal environments.

Background: Applying organic amendments to vineyard soil improves soil properties and vine development by increasing soil water retention and nutrient content. However, little is known about how organic mulches modify grapevine phenolic composition. This study analysed the phenolic profile in the leaves, canes, and grape skins of Tempranillo over 3 years in two vineyard locations with three organic mulches: spent mushroom compost (SMC), grapevine pruning debris (GPD) and straw (STR), as well as two conventional soil practices: herbicide (HERB) and tillage (TILL).

This study evaluated the optomechanical and structural properties of individual macroscopic layers in swine skin tissues treated with a nontoxic optical clearing agent. The clearing agent was prepared by dissolving 2,2'-thiodiethanol in a phosphate-buffered solution and applied for up to 6 days. Prolonged clearing increased both the total and unscattered transmittance.

In order to relate nanoparticle properties to function, fast and detailed particle characterization is needed. The ability to characterize nanoparticle samples using optical microscopy techniques has drastically improved over the past few decades; consequently, there are now numerous microscopy methods available for detailed characterization of particles with nanometric size. However, there is currently no "one size fits all" solution to the problem of nanoparticle characterization.
