Active Learning‐Guided Accelerated Discovery of Ultra‐Efficient High‐Entropy Thermoelectrics

Advanced Materials, Volume 38, Issue 10, 17 February 2026.
An active learning framework is introduced for the accelerated discovery of high‐entropy chalcogenides with superior thermoelectric performance. Only 80 targeted syntheses, selected from 16206 possible combinations, led to three high‐performance compositions, demonstrating the remarkable efficiency of data‐driven guidance in experimental materials ...

Grid‐Shaped, Vertically Aligned Carbon Nanotube Architectures for Electrical, Optical, and Mechanical Bolometers

Advanced Sensor Research, Volume 5, Issue 2, February 2026.
The small geometry of nano/micro sensor devices, down to 3 × 3 µm2, makes them ideal for reliable large‐scale integration into sensor arrays for single‐use biomedical, industrial, and security applications. These devices allow for the efficient conversion of ultraviolet to terahertz radiation into electrical or optical output signals using simple ...

Long‐Term Cycling Stability of Sodium/Sodium Ion Cells Probed by In Situ Solid‐State NMR Spectroscopy

Batteries &Supercaps, Volume 9, Issue 2, February 2026.
The suitability of 23Na in situ solid‐state nuclear magnetic resonance (NMR) spectroscopy for long‐term studies of sodium/sodium ion cells is tested. Using silicon carbonitride and hard carbon working electrodes, local structures are analyzed up to the point of capacity degradation and cell failure.

Hydrogenation Properties of LnAl₂ (Ln = La, Eu, Yb), LaGa₂, LaSi₂ and the Crystal Structure of LaGa₂H_0.71(2)

Crystals, 2019
Many Zintl phases take up hydrogen and form hydrides. Hydrogen atoms occupy interstitial sites formed by alkali or alkaline earth metals and/or bind covalently to the polyanions.
