Intrabandgap States Engineering in Functionalized Nanodiamond to Generate Solvated Electrons for Photocatalysis Under Solar Illumination

open access: yesAdvanced Functional Materials, Volume 36, Issue 37, 7 May 2026.
The negative electron affinity of diamond allows to emit highly reductive electrons. By introducing intra‐bandgap states and an optimized electron transfer mechanism by surface functionalization with Ru(bpy)3, the formation of solvated electrons is achieved upon solar irradiation.

Boosting Photo‐Pyroelectric Effect via Tunable Polarization and Interfacial Defect Engineering

open access: yesAdvanced Science, Volume 13, Issue 25, 4 May 2026.
This study reports Ba(Ti0.85Zr0.15)O3 nanocatalysts with enhanced polarization and oxygen‐vacancy‐rich interfaces for efficient NIR‐II photo‐pyroelectric therapy. Zr doping boosts the pyroelectric coefficient and accelerates polarization switching, while oxygen vacancies improve photothermal conversion and surface reactivity.

Losartan API and Nitrosamines Impurities—Stability Profile Investigation Using HPLC, LC‐MS, and In Silico Assessment

open access: yesJournal of Separation Science, Volume 49, Issue 5, May 2026.
ABSTRACT Nitrosamines are potent genotoxic impurities with well reported mutagenic and carcinogenic effects. Their presence has been detected in several pharmaceutical products among them losartan, an angiotensin II receptor blocker. Considering the risks already reported for these impurities, the present study aimed to investigate the influence of ...

Progress Toward Efficient Wide‐Gap Cu(In,Ga)(S,Se)2 Thin‐Film Solar Cells

open access: yesProgress in Photovoltaics: Research and Applications, Volume 34, Issue 5, Page 567-588, May 2026.
Wide‐gap Cu (In,Ga)(S,Se)2 thin‐film solar cells are studied in view of their performance, limitations, and opportunities for further optimization. Different sources of open circuit voltage limitations were discussed and weighted. Interface recombination appears the main recombination channel, which however can be influenced heavy alkali treatment ...
