Tuning the Photochemistry of Entatic State Model Systems

Zeitschrift für anorganische und allgemeine Chemie, Volume 652, Issue 9, 3 June 2026.
We present the photochemistry of the entatic state model [Cu(DMEGqu)2]+/2+, a copper guanidino‐quinoline complex pair. By transient IR and UV/Vis spectroscopy, we obtained the lifetimes of the different excited states. We show that the structural effect of the guanidine tunes the photochemistry of this entatic state model.

Preparation of Rocksalt‐Type Semiconductor Ca2TaN3 via Hot Isostatic Pressing

Zeitschrift für anorganische und allgemeine Chemie, Volume 652, Issue 9, 3 June 2026.
The rocksalt‐type nitride Ca2TaN3 was prepared via hot isostatic pressing at 1400°C and 150 MPa of static dinitrogen pressure. The yellow compound is a semiconductor with a bandgap of 2.5 eV. The rocksalt‐type double nitride Ca2TaN3 was synthesized via hot isostatic pressing (HIP) at 1400°C and 150 MPa static dinitrogen pressure from Ca3N2 and Ta3N5 ...

From Single Atoms to Nanoparticles: Pathways Toward Efficient and Durable Pt/TiO2 Photocatalysts

Advanced Functional Materials, Volume 36, Issue 44, 1 June 2026.
Platinum single atoms on TiO2 nanosheets evolve into clusters and nanoparticles under ethanol photoreforming and thermal treatments. By controlling deposition and post‐treatments, particle size and location on specific facets are modulated. The study reveals how stability pathways determine efficiency, guiding the design of more durable photocatalysts.

Ultrasmall Platinum Nanoparticles for Radiation‐Enhanced Cancer Therapy

Advanced Functional Materials, Volume 36, Issue 45, 5 June 2026.
This work proposes a nanomedicine‐based strategy to enhance X‐ray radiotherapy for cancer treatment. Ultrasmall Pt‐NPs exhibit catalase‐like activity that may contribute to modulation of the tumor microenvironment and amplify interactions between radiation and biological matter, leading to increased DNA damage.

Luminescence and Photochromism in Lanthanide‐Doped Hackmanites

Advanced Optical Materials, Volume 14, Issue 23, 19 June 2026.
Lanthanide‐doped lithium hackmanite derivatives are prepared utilizing a doped LiAlSiO4 precursor to modify luminescent and photochromic properties. Upon UV excitation, europium doping results in green Eu2+ persistent luminescence from shallow traps. Contrarily, samarium doping induces unusual near‐infrared photochromism.
