Macromolecular Materials and Engineering, Volume 311, Issue 5, May 2026.One‐step 3D printing combined with in‐situ self‐assembly of behenic acid creates hierarchical polypropylene surfaces with micro‐ and nanostructures. The resulting material exhibits superhydrophobicity with a contact angle of 163 (±2)°, self‐healing, and high scratch resistance, while reducing initial bacterial adhesion by 87%. ABSTRACT Superhydrophobic

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
