Metasurface Enhanced Photothermal Cement Foam for Robust and High‐Throughput Seawater Desalination

Carbon Energy, Volume 8, Issue 5, May 2026.
Schematic of 3D metasurface‐enhanced cement foam for robust and high‐throughput seawater desalination. This study presents a cement‐based solar evaporator (CSE) fabricated in one step via viscoelastic lithography with simple negative pressure. In addition to boosting solar‐to‐vapor conversion efficiency via excellent light‐harvesting capacity, the ...

Midbrain PAG Astrocytes Modulate Mouse Defensive and Panic‐Like Behaviors

Advanced Science, Volume 13, Issue 19, 2 April 2026.
Astrocytes in the midbrain periaqueductal gray (PAG) dynamically encode threat intensity and shape defensive action selection in mice. Real‐time Ca2+ imaging reveals robust astrocytic activation during predator odor and CO2 exposure. Aberrant astrocytic Ca2+ overactivation disrupts goal‐directed escape, biases behavior toward freezing, and induces ...

Laboratory Evaluation of the Physicochemical Properties of Novel Pre‐Mixed Putty‐Type Bioceramic Materials

Australian Endodontic Journal, Volume 52, Issue 1, Page 92-98, April 2026.
ABSTRACT This study aimed to compare the physicochemical properties of EndoSequence Root Repair Material (ERRM) Fast and CeraPutty with ProRoot MTA and Biodentine, focusing on setting time, radiopacity, microhardness, and pH. Setting time was measured using a Gilmore‐type indenter applied every 5 min until no indentation was observed (n = 15 per group).
