Photoluminescent UV Light Modulation via Anisometric Carbon Nanodots for UV–Visible Shutter and UV Sensor

open access: yesAdvanced Functional Materials, Volume 36, Issue 10, 2 February 2026.
Anisometric carbon nanodots are synthesized directly from a liquid crystal precursor and embedded into polymer network liquid crystals to create soft, multifunctional photonic films. These hybrid devices exhibit polarized photoluminescence, broad UV absorption, and fast, electrically tunable light modulation.

Temperature‐Dependent Zinc Oxide Cathodoluminescence: Toward Compact Wavelength‐Tunable Solid‐State Photoionization Sources

open access: yesAdvanced Optical Materials, Volume 14, Issue 6, 9 February 2026.
A proof‐of‐concept of a thermally‐tunable cathodoluminescence‐based light source is demonstrated using a wide‐bandgap z‐cut ZnO crystal as anode, resulting in the ultraviolet (UV) emission peak shifting from 398 nm to ~409 nm (3.115‐3.032 eV). Our results establish the feasibility of a compact, field‐deployable UV source with potential for gas sensing ...

Recent Advances in Mediator and Proton Relay Usage in Molecular Catalysis

open access: yesAdvanced Science, Volume 13, Issue 8, 9 February 2026.
The use of electron–proton transfer mediators, redox mediators, and proton relays in synergy with molecular catalysts in energy‐related small‐molecule and organic transformations is discussed, with a focus on recent advances. Linear free‐energy relationship and catalytic Tafel plots provide a systematic foundation for benchmarking these catalytic ...

Burn Selection: How Fire Injury Shaped Human Evolution

open access: yesBioEssays, Volume 48, Issue 2, February 2026.
Intentional fire use exposed humans and their ancestors to high‐temperature burn injury, a risk rare in other species, bringing major survival benefits and technologies but also repeated exposure to extreme heat. The Burn Selection Hypothesis reframes this cost of fire mastery as a unique selective pressure, which shaped our evolution.

Polyethylene Terephthalate Monomerization via Glycolysis and Methanolysis Using Metal‐Free Basic Carbocatalyst

open access: yesChemCatChem, Volume 18, Issue 3, 12 February 2026.
The image represents a sustainable solution via chemical recycling of waste PET bottle‐to‐rPET bottle via monomerization process (glycolysis and methanolysis) in the presence of metal‐free basic carbocatalyst. Abstract The giant amount of disposed Polyethylene Terephthalate (PET) has become a big environmental challenge.
