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

Microscopy Research and Technique, Volume 89, Issue 6, Page 932-947, June 2026.
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.

Study on the Permeability of Modified Bentonite Slurry in Landfill

Advances in Materials Science and Engineering, 2020
The impermeability of cutoff wall is one of the most important factors affecting the life of landfill. Hence, we used sodium carboxymethyl cellulose to modify bentonite and developed a modified bentonite-cement-fly ash antiseepage slurry with a low ...

Erosion Process of Polycarboxylate Cements in Organic Acids

Dental Materials Journal, 1983
The amounts of Zn and Mg eluted from the zinc polycarboxylate cement into acetic, lactic and citric acids increased with an increase in the formation constant of the acid-Zn or -Mg complexes. The erosion process consisted of two processes, namely, dissolution of the unreacted cement powder and decomposition of the matrix.

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 ...

Chemical and Microstructural Evolution of Cement Pastes with Additives and SCMs During the First 24 h

Journal of the American Ceramic Society, Volume 109, Issue 5, May 2026.
ABSTRACT Early‐age chemical evolution governs the development of hydrate assemblages and microstructure in cementitious systems, especially when additives and supplementary cementitious materials are incorporated. This study investigates the first 24 h of hydration in Portland cement pastes modified with selected additives and supplementary ...

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 ...
