Linking Process‐Induced Degradation to Mechanical Property Deterioration in Flax Fiber–Reinforced Bio‐Polymer Matrix Composites

Polymer Composites, Volume 47, Issue 10, Page 9377-9391, 20 May 2026.
Effect of processing‐induced thermal degradation on the mechanical performance of thermoplastic flax fiber composites. ABSTRACT The drawback of biobased polymer matrix composites (PMCs) is their limited temperature stability, resulting from degradation, which restricts their processability in established composite manufacturing processes requiring ...

Derjaguin’s Water II: a surface hydration phenomenon

Substantia, 2019
B.V. Derjaguin’s promotion of anomalous water II (polywater) in the early 1970s was an embarrassing point in the career of an illustrious chemist, and quickly repudiated by Derjaguin himself. Water II does not exist as a bulk liquid.

ZnO‐Functionalized Silicon Carbide Ceramic Membranes for Removing Impurities From Biodiesel

International Journal of Ceramic Engineering &Science, Volume 8, Issue 3, May 2026.
Silicon carbide (SiC) ceramic membranes functionalized with zinc oxide (ZnO) were assessed for biodiesel purification through crossflow filtration. The ZnO–SiC membranes effectively retained metallic impurities, especially calcium, sodium, and phosphorus, achieving levels that meet biodiesel quality standards.

Fabrication of a Plate-Type Porous Stainless Steel 316L Powder Filter with Different Pore Structures without Use of a Binder [PDF]

Archives of Metallurgy and Materials
Generally, when fabricating porous filters using metal powder, about 1 to 2 wt% of a binder is added to increase the formability of the metal powder. If the binder is not completely removed through a debinding and sintering process, however it can cause ...

Enhancing Aluminum Matrix Composites With High‐Entropy Alloys: A Study of Mechanical, Thermal, and Electrical Properties via Powder Metallurgy

Nano Select, Volume 7, Issue 5, May 2026.
ABSTRACT This study investigates the incorporation of high‐entropy alloys (HEAs) into aluminum matrix composites (AMCs) via powder metallurgy to improve their mechanical, thermal, and electrical properties. Significant improvements in mechanical performance were observed by systematically varying HEA content from 0% to 30%.

Achieving Superior Strength‐Ductility Synergy in Bionic Magnesium‐Iron Composites by Topological Optimization

Rare Metals, Volume 45, Issue 5, May 2026.
ABSTRACT Magnesium (Mg)‐based composites are regarded as promising lightweight materials with significant potential for structural applications. The structure–property relationships of bionic Mg‐based composites remain unclear. Herein, three honeycomb‐like Mg‐Fe composites are fabricated to uncover the underlying strengthening mechanisms.
