W‐N‐C Tandem Catalytic Centers Mediating Efficient Charge Transfer for the Enhanced Radical‐Path U(VI) Photoreduction

Advanced Science, Volume 13, Issue 44, 7 August 2026.
This work constructed a tandem W−N−C center to simultaneously achieve the regulation of reaction pathways and optimization of charge separation efficiency. The Lewis‐acidic W6+ sites activated O2 to generate O2−$O_2^ - $, with enhanced charge separation via electronic modulation, steering U(VI) reduction down an efficient radical pathway.

Counterion Effects on the Properties and Reactivity of Charged Photoredox Catalysts

ChemPhotoChem, Volume 10, Issue 8, August 2026.
The choice of a counterion for a charged photocatalyst has long been overlooked. In this review, we summarize recent reports on counterion effects in photocatalysis, providing readers with a comprehensive theoretical understanding and synthetic applications for the use of a carefully chosen counterion. Electrostatic interactions represent the strongest

Explainable Machine Learning With Hybrid Feature Selection for Thyroid Disease Classification: A Case Study in Bangladesh

Engineering Reports, Volume 8, Issue 8, August 2026.
Our research establishes a hybrid feature selection and ensemble machine learning pipeline for the classification of euthyroid, hyperthyroid, hypothyroid, and subclinical hypo‐ and hyperthyroid disorders. Variance Threshold with Backward Feature Elimination attained nearly 100% accuracy, while SHAP and LIME clarified the significance of features and ...

Just Transition Toward Clean Energy Access With Focus on Lead‐Based Perovskite Solar Cell Technology: Lessons, Experiences, and Future Perspectives

Global Challenges, Volume 10, Issue 8, August 2026.
To intentionally mitigate energy poverty in underserved communities, advanced perovskite energy technologies such as lead‐based perovskite solar cells are necessary. However, in future deployment of these materials, energy justice, equity, inclusivity and environmental sustainability must be taken into account.

Liquid Crystal Elastomers Filaments for Adaptive Textiles and Soft Robotics: A Processing‐Centric Review

Macromolecular Rapid Communications, Volume 47, Issue 15, 4 August 2026.
Liquid crystal elastomer (LCE) filaments are fabricated through extrusion with in‐process UV curing, enabling controlled flow alignment and network locking of mesogens. The resulting structure responds to thermal or optical stimuli, inducing molecular reorientation and macroscopic contraction.
