Physical Origin of Temperature Induced Activation Energy Switching in Electrically Conductive Cement

open access: yesAdvanced Science, EarlyView.
The temperature‐induced Arrhenius activation energy switching phenomenon of electrical conduction in electrically conductive cement originates from structural degradation within the biphasic ionic‐electronic conduction architecture and shows percolation‐governed characteristics: pore network opening dominates the low‐percolation regime with downward ...

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

open access: yesCarbon Energy, EarlyView.
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 ...

In Vitro Evaluation of Novel Calcium Silicate‐Based and Resin‐Modified Calcium Silicate Materials: Cytocompatibility and Mineralization Potential on Human Dental Pulp Stem Cells for Pulp Repair

open access: yesMicroscopy Research and Technique, EarlyView.
This study demonstrates that Biodentine XP exhibits superior cytocompatibility, promotes odontogenic differentiation, and enhances mineralization in human dental pulp stem cells, supporting its use in regenerative endodontics. Resin‐modified materials showed lower bioactivity, highlighting the importance of material composition in pulp therapy outcomes.
