Eco‐Friendly Preparation of Porous Starch via Water‐Induced Amylose Solubilization
ABSTRACT Starch is a safe and biocompatible excipient in pharmaceutical formulations. Introducing pores into its granules transforms it into a biodegradable carrier suitable for drug delivery. Various strategies have been developed to induce pore formation, including physical methods (e.g., microwave, ultrasound), chemical methods (e.g., solvent ...

An Analysis of the Shapes of Interstellar Extinction Curves. VI. The Near-IR Extinction Law
We combine new HST/ACS observations and existing data to investigate the wavelength dependence of NIR extinction. Previous studies suggest a power-law form, with a "universal" value of the exponent, although some recent observations indicate that ...

HST Spectrophotometry and Models for Solar Analogs
Absolute flux distributions for seven solar analog stars are measured from 0.3 to 2.5 \mu m by HST spectrophotometry.In order to predict the longer wavelength mid-IR fluxes that are required for JWST calibration, the HST SEDs are fit with Castelli ...

Invasive plants optimize leaf nitrogen allocation in photosynthesis
Summary Invasive plants often outcompete co‐occurring native species by expressing acquisitive functional traits that promote high photosynthetic capacity. However, it remains unclear whether these traits are newly evolved in the introduced (‘away’) range or if invaders arrived preadapted with superior traits from their native (‘home’) range.

By exploiting the structural benefits of PHI, we synthesized CoPHI with atomically dispersed cobalt sites at high density. This architecture enables efficient nitrate ion adsorption, promotes water dissociation, and enhances *H generation on the catalyst surface, thereby significantly improving electrochemical nitrate reduction performance.

Mechanistic Insights Into the Photosensitizing Properties of the Topical Retinoid Tazarotene
Light‐activated retinoids: Tazarotene and its active metabolite tazarotenic acid form long‐lived triplet excited states upon UVA irradiation, generating singlet oxygen and promoting photochemical reactions. These processes correlate with reduced fibroblast viability under light exposure, revealing potential phototoxicity and implications for combined ...

Analysis of a thioether lubricant by infrared Fourier microemission spectrophotometry [PDF]
An infrared Fourier microemission spectrophotometer is used to obtain spectra (wavenumber range, 630 to 1230 0.1 cm) from microgram quantities of thioether lubricant samples deposited on aluminum foil.
