Optical Mapping of Pacing‐Elicited Slow Waves in the Swine Stomach: Role of Virtual Electrodes

Neurogastroenterology &Motility, Volume 38, Issue 5, May 2026.
Unipolar electrical pacing stimuli delivered to the stomach wall induce adjacent regions of both depolarized and hyperpolarized tissue known as virtual electrodes. Electrical slow waves elicited by pacing start from depolarized virtual electrodes approximately 1 cm from the pacing electrode site and not from the electrode site itself.

3D‐Printed Geopolymer as a Basic Heterogeneous Catalyst for the Synthesis of α‐Cyanoacrylates Through the Knoevenagel Condensation

European Journal of Organic Chemistry, Volume 29, Issue 16, 25 April 2026.
3D‐printed geopolymers are presented as efficient and reusable heterogeneous catalysts for the Knoevenagel condensation. Under mild and green conditions, they promote the high‐yield synthesis of diverse α‐cyanoacrylates with remarkable stability and scalability.

Electrical Conductivities of Conductors, Semiconductors, and Their Mixtures at Elevated Temperatures

Advanced Engineering Materials, Volume 28, Issue 8, 22 April 2026.
This article presents a comprehensive review of temperature‐dependent electrical conductivity data for multiple material classes at elevated temperatures, highlighting a persistent conductivity gap between metals and semiconductors in the range of 102$\left(10\right)^{2}$– 107$\left(10\right)^{7}$ S/m. Metal–ceramic irregular metamaterials are proposed

Multiple Time‐Scale Homogenization of Coupled Corrosion‐Fatigue in Structural Concrete

International Journal for Numerical Methods in Engineering, Volume 127, Issue 7, 15 April 2026.
ABSTRACT Reinforced concrete structures exposed to chloride‐rich environments and cyclic mechanical loading experience simultaneous corrosion of steel reinforcement and fatigue‐induced concrete cracking, leading to complex, nonlinear degradation that cannot be accurately captured by conventional sequential analyses.
