Systematic Evaluation of Reaction Phase Effects on Photocatalytic CO2 Reduction Using Cu‐Doped SrTiO3

open access: yesGlobal Challenges, Volume 10, Issue 9, September 2026.
How much does the reaction environment matter in photocatalytic CO2 reduction? Using Cu‐doped SrTiO3 as a model catalyst, the solid–gas configuration is found to outperform liquid and pressurized systems, revealing that reaction‐phase engineering plays a decisive role in controlling efficiency and product selectivity. ABSTRACT Carbon dioxide conversion

Roadmap for the implementation of particle minibeam therapy

open access: yesMedical Physics, Volume 53, Issue 9, September 2026.
Abstract Particle minibeam therapy (PMBT) has emerged as an advanced modality within spatially fractionated radiation therapy, using the physical properties of protons, ions, and electrons to achieve superior normal tissue sparing whilst preserving spatial dose distribution at depths that are unachievable in conventional kV or MV X‐rays.

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 ...

Anti‐Globalization Dynamics and Africa's Structural Transformation: Identifying Avoidable Environmental Degradation Thresholds

open access: yesSustainable Development, Volume 34, Issue 5, Page 6869-6886, September 2026.
ABSTRACT This study pursues a dual objective. First, it investigates the unconditional impact of anti‐globalization on structural transformation in Africa. Second, it explores how environmental degradation interacts with anti‐globalization to influence structural transformation. The analysis focuses on 52 African countries over the period 2005–2023. To

Unveiling Ca9N4Te3: A New Motif in Alkaline‐Earth Metal Chalcogenide Nitrides: A Combined Experimental and Computational Study

open access: yesZeitschrift für anorganische und allgemeine Chemie, Volume 652, Issue 13, 1 September 2026.
The unique double monocapped trigonal cupola coordination polyhedra of Te(2) atoms inside the crystal structure of Ca9N4Te3. Green, moisture‐sensitive Ca9N4Te3 was obtained from Ca/Na flux at 1173 K as a by‐product of reddish‐brown Ca6N2Te3 and crystallizes in the trigonal space group R3¯$\overline{3}$ (No. 148, Z = 3).
