Self‐Texturing Scratch‐Resistant and Bacteria‐Repellent Superhydrophobic Polypropylene Surfaces Through Extrusion‐Based Additive Manufacturing

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

Plastic optical fiber as a tool for experimenting with simple pendulum

Revista Brasileira de Ensino de Física
In this paper an experiment with plastic optical fiber to control the motion of a simple pendulum was described. The monitoring system of pendulum position is based on bend loss in plastic optical fiber which depends of bend radius. As a recording device

Attending to Preservice Teachers' Assets: Beliefs and Practices for Supporting Expansive Sensemaking in Elementary Science

Science Education, Volume 110, Issue 3, Page 756-779, May 2026.
ABSTRACT Preservice elementary science teachers' beliefs and practices influence the kinds of adaptations they make to curriculum materials and the extent to which they are able to enact justice‐oriented science lessons. Through this qualitative study, we explored the beliefs and practices of five focal preservice teachers through an analysis of their ...

Substitution of Ti by Nb in Maraging Steel: Effects on Strengthening Mechanisms and Crystallographic Behavior

steel research international, Volume 97, Issue 5, Page 2672-2692, May 2026.
This work demonstrates that replacing Ti with Nb in maraging steel forms nanoscale Nb–Mo particles along boundaries, strengthening the alloy without relying on Ti phases. Heat‐treatment tuning promotes uniform crystal orientation and balanced grain boundaries, enabling strong yet ductile behavior.

Modelling non‐linear psychological processes: Reviewing and evaluating non‐parametric approaches and their applicability to intensive longitudinal data

British Journal of Mathematical and Statistical Psychology, Volume 79, Issue 2, Page 263-293, May 2026.
Abstract Psychological concepts are increasingly understood as complex dynamic systems that change over time. To study these complex systems, researchers are increasingly gathering intensive longitudinal data (ILD), revealing non‐linear phenomena such as asymptotic growth, mean‐level switching, and regulatory oscillations.
