Coupling electric and magnetic dipoles in Janus nanoplatelets via surface-selective hybridization

Coupling electric and magnetic dipoles within nanoscale building blocks offers a promising strategy for creating hybrid materials with coupled magnetic and electric functionality. Here, we demonstrate a proof-of-concept approach for realizing this concept in Janus nanoparticles t...

Boosting NIR Emissions and Thermal Resistance in Cr3+-Doped MgGa2O4 Semiconductor Microcrystals by Energy Transfer for Smart Detection

High-radiant-intensity broadband near-infrared (NIR) emitters are highly desirable for nondestructive testing, night-vision imaging, and information encryption. However, the exploration of phosphors that possess both high luminous efficiency and outstanding thermal stability cont...

Extending the mineralogy of U 6+ (VII.): Kristekite, [Cu 2 (H 2 O) 4 (UO 2 )(SeO 3 ) 3 ]·4H 2 O, a new mineral from Příbram, Czech Republic.

The new mineral kristekite (IMA2025-101), [Cu 2 (H 2 O) 4 (UO 2 )(SeO 3 ) 3 ]•4H 2 O, was found in the dump material of the former uranium mine at Bytíz, near Příbram, Central Bohemia, Czech Republic, where it occurs as hedgehog-like aggregates, consisting of yellowish-green tabu...
