Titanium Dioxide Induced Immobilization of Small Platinum Nanoparticles on Carbon Spherogels: A Strategy Towards Stable and Efficient Electrocatalysts for the Hydrogen Evolution Reaction

open access: yesSmall, Volume 22, Issue 28, 18 May 2026.
Platinum nanoparticles are immobilized on hollow carbon spherogels using supercritical deposition, enabling precise control over nanoparticle size, loading, and spatial distribution. Incorporation of an internal TiO2 sublayer in the hollow sphere support induces enhanced metal–support interactions, markedly improving hydrogen evolution activity and ...

Controls on Magma Output From Stromboli's Plumbing System

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 5, May 2026.
Abstract Quantifying magma output over variable timescales is essential for understanding persistently active volcanoes. We analyze magma output at Stromboli (during 2000–2025) using satellite thermal data integrated with a comprehensive database of volcanic activity.

Contributions of Microgravity Test Results to the Design of Spacecraft Fire Safety Systems [PDF]

open access: yes
Experiments conducted in spacecraft and drop towers show that thin-sheet materials have reduced flammability ranges and flame-spread rates under quiescent low-gravity environments (microgravity) as compared to normal gravity.

Structures of variants of Escherichia coli flavodiiron‐type nitric oxide reductase reveal changes in the di‐iron site

open access: yesActa Crystallographica Section D, Volume 82, Issue 5, Page 457-470, May 2026.
Flavodiiron proteins (FDPs) are di‐iron enzymes that reduce NO and/or O2 with distinct substrate selectivity. We have produced E. coli FDP variants targeting second coordination‐sphere residues and determined their structures. Although the kinetics remained unchanged, the E.

Valorization of Rice By‐Products Through Conventional and Emerging Extraction Technologies: Trends, Challenges, and Applications

open access: yesComprehensive Reviews in Food Science and Food Safety, Volume 25, Issue 3, May 2026.
ABSTRACT Rice and by‐products, such as rice bran (RB), defatted RB (DRB), rice husk (RH), rice straw (RS), and broken rice, represent abundant yet underutilized resources within the rice value chain. These fractions are nutritionally dense, containing proteins, lipids, dietary fibers, phenolics, and other bioactives that can be transformed into high ...
