Layered perovskites like titanium-added calcium manganese oxide ceramics have attracted attention as materials that can prevent solar heat absorption by reflecting near-infrared (NIR) radiation better than commercial pigments. However, the mechanism underlying their high NIR reflectivity is unclear. Now, researchers have adopted a combination of experimental and theoretical approaches to provide useful insights into the structure, properties, and functioning of these layered perovskites that can be extended to a broad range of crystalline ceramics.

Fluorine-containing gases -- including so-called per- or polyfluorinated hydrocarbons, or PFCs -- have a significant share in global warming. Researchers recently developed new crystalline materials that can selectively adsorb the molecules of such carbon-fluorine bonds. They hope that these porous crystals may be useful for targeted binding and recovery of PFCs.

Molecular 2D materials find immense applications in materials science, owing to their wide structural variety and easy controllability. Establishing a simple and efficient method for their synthesis is, therefore, important. Now, scientists present a simple method for synthesizing heterolayer coordination nanosheets, a promising 2D material, shedding light on how certain chemical coordination reactions occur at liquid-liquid interfaces. Their method could help develop novel 2D materials with applications in optoelectronic devices.
