Prediction of Cement Paste Elastic Properties via Computational Homogenization Using Digital Microstructures

International Journal for Numerical Methods in Engineering, Volume 126, Issue 24, 30 December 2025.
ABSTRACT This paper addresses the computational homogenization of cement paste, considering different types and sizes of representative volume elements (RVEs). Two microstructure models are examined: one generated from the simulation of hydration processes and the other based on microtomographic experimental data.

Self‐Assembly of Bent‐Core Nematics in Nanopores

Small, Volume 21, Issue 49, December 10, 2025.
Bent‐core nematic liquid crystals like CB7CB exhibit tunable molecular organization and optical responses when confined in cylindrical nanochannels of anodic aluminum oxide and silica. The study investigates how confinement–from weak to strong–modulates phase behavior, revealing heliconical structures, paranematic states, and birefringence patterns ...
