Contribution of One‐Electron Oxidation of Purine and Pyrimidine Bases to the Photo‐ and Radiation‐Induced Damage to Cellular DNA

ChemPhysChem, Volume 27, Issue 15, 14 August 2026.
One‐electron oxidation of purine and pyrimidine bases of isolated and cellular DNA generates related reactive base radical cations that are converted into final decomposition products through deprotonation and hydration. In the case of guanine, the most susceptible nucleobase to one‐electron oxidants, 8‐hydroxy‐7,8‐dihydroguanyl radical, thus formed by

Review of Amorphous Gallium Oxide: From Material Synthesis to Device Applications

physica status solidi (a), Volume 223, Issue 15, 5 August 2026.
Amorphous gallium oxide (a‐Ga2O3) is reviewed as a promising ultra‐wide‐bandgap material for solar‐blind UV photodetectors. The influence of structural disorder, defect states, and trap‐assisted transport on optical and electronic performance is examined.

Decoupling Light Absorption From Photocatalytic Reactivity in TiO2 via Defect and Interfacial Engineering

Advanced Functional Materials, Volume 36, Issue 62, 3 August 2026.
A hybrid photoprotective material integrates N‐doped TiO2 with a metal‐phenolic network (MPN) to achieve broad‐spectrum attenuation and robust reactive oxygen species (ROS) suppression. Nitrogen doping extends attenuation into the UVA/high energy visible light (HEV) regions and facilitates fast charge recombination to inhibit ROS formation.

Sustainable Carbon Fibers Enable Stable Long‐Term Lithium Metal Deposition for Prospective Zero‐Excess Lithium Metal Batteries

Advanced Energy Materials, Volume 16, Issue 30, 12 August 2026.
This work presents lightweight, lignin‐derived carbon fiber current collectors that enable controlled lithium deposition. Structural defects and intermediate‐sized pores stabilize pre‐nucleation quasi‐metallic lithium clusters, promoting uniform lithium plating and stripping.
