Transition Metal Chalcogenides: Perspectives on Their Applications for Nitrate Reduction

open access: yesChemistryOpen, Volume 15, Issue 9, September 2026.
This review paper reports the syntheses, properties, and applications of TMCs for electrochemical reduction of nitrate to ammonia. Various studies revealed that the conversion of nitrate to ammonia is principally the electrocatalytic hydrogenation of nitrate and the rate and yield of ammonia is competitively challenged by hydrogen evolution reaction ...

Mesoporous Hexametallic High‐Entropy Alloy Nanotubes With Multicomponent Electronic Modulation for Efficient Bifunctional Catalysis

open access: yesRare Metals, Volume 45, Issue 9, September 2026.
ABSTRACT Platinum‐based electrocatalysts are fundamentally constrained by strong oxygen binding, which restricts the oxygen reduction reaction (ORR) kinetics, and by severe CO poisoning, which hinders the methanol oxidation reaction (MOR). To address these limitations, we synthesized PdPtRuIrRhNi high‐entropy alloy (HEA) mesoporous nanotubes that ...

Molecularly Mediated Assembly of Metal Nanoparticles With Multifunctional Interfaces for Selective Detection of Small Gas Molecules

open access: yesSmall, Volume 22, Issue 52, 16 September 2026.
This work demonstrates a conceptual framework of three types of cooperative interaction pathways in molecularly assembled nanoparticle chemiresistors. Their relative contributions depend on nanoparticle composition, linker chemistry, film architecture, and analyte identity, modulating the effective tunneling barrier (Φ), interparticle spacing (d), and ...

Characterization of a Portable Computed Tomography System for In Situ Analysis of Wooden Sculptures in Cultural Heritage

open access: yesX-Ray Spectrometry, Volume 55, Issue 5, Page 763-777, September/October 2026.
ABSTRACT Portable X‐ray computed tomography (portable CT) has become an important tool for the non‐destructive investigation of cultural heritage objects, particularly when in situ analysis is required. This work presents the experimental characterization and application of a transportable cone‐beam CT system designed for the inspection of large and ...

A Solar Analog Model for Decrease in Far Ultraviolet Irradiance Under a Grand Minimum

open access: yesEarth and Space Science, Volume 13, Issue 9, September 2026.
Abstract Solar analog field stars having a range of magnetic activity can provide an estimate of solar spectral irradiance (SSI) variability relevant to understanding the Sun's influence on terrestrial climate. This approach is particularly useful for far ultraviolet (FUV) irradiance that cannot be observed from the Earth surface.
