Long‐Lived Photoluminescence of Photostable One‐Dimensional Picoperovskites

Small Science, Volume 6, Issue 2, February 2026.
We study one‐dimensional metal halide perovskite crystals encapsulated in single‐wall nanotubes, so‐called picoperovskites, using optical spectroscopy. Polarized micro‐photoluminescence (PL) reveals bright emission from aligned bundles of picoperovskites with clear linear polarization along the bundle axis.

Cluster Models for Next‐Generation, Machine‐Learning‐Based Energy Functions for Molecular Simulations

Small Structures, Volume 7, Issue 2, February 2026.
This work describes how to conceive validated mixed machine learned/empirical energy functions based on finite‐sized molecular clusters for condensed phase simulations. Energy functions for pure and heterogeneous systems are one of the backbones for molecular simulation of condensed phase systems.

Nanodiamond–silicon nitride composites for CO2 capture technology

International Journal of Applied Ceramic Technology, Volume 23, Issue 1, February 2026.
Abstract Innovative nanodiamond (ND)–silicon nitride polymer‐derived ceramics with different concentrations of nanocarbon phase were developed within the present work and their performance as adsorbent materials for CO2 was established. The novel preparative approach consists in the synthesis of a polysilsesquiazane in the presence of different ...

Single‐source precursor synthesis of a compositionally complex early transitional metal nitride (V, Nb, Ta, Mo, W)Nx and its high temperature stability

International Journal of Applied Ceramic Technology, Volume 23, Issue 1, February 2026.
Abstract Compositionally complex transitional metal nitrides are an interesting class of ceramics with superior chemical, thermal, and mechanical stability, with a high potential in ultra‐high temperature applications and catalysis. The exceptionality in the properties may partly be explained as a consequence of their high configuration entropy ...
