Advanced Engineering Materials, EarlyView.Scandium (Sc)‐doped AlCoCrFeMo HEA coatings are fabricated via flame spraying with 0.1, 0.3, and 0.5 wt% Sc additions. Among these, the HEA‐Sc0.3 coating exhibits the highest corrosion resistance, indicated by a more positive corrosion potential and lower current density.

Mineral chemistry and termometry of the high-Mg ultramafic lava flows (Komatiite), NE Iran: evidence of plume-arc interaction in the Upper Paleozoic Mashhad-Fariman subduction zone [PDF]
پترولوژی, 2019 In the northeast of Iran, there are some outcrops of high-Mg ultramafic volcanic rocks. These rocks have been interpreted as an ideal ophiolite sequence related to the closure of Paleo-Tethys. According to detailed field observations, the komatiitic lava

Advanced Engineering Materials, EarlyView.This study proposes a potential device design for joint cartilage replacement. Silica‐polytetrahydrofuran (SiO2‐PolyTHF) hybrids with customizable mechanical properties were developed to mimic the characteristics of a natural meniscus. These were synthesized through a two‐pot sol–gel hybrid process.

Electrodeposition in Structural Lattices of Variable Architectures
Advanced Engineering Materials, EarlyView.Electrodeposition enables geometry‐sensitive, autonomous void filling while simultaneously tuning chemical and mechanical properties. The development of approaches that can autonomously fill and heal material voids and yield composites with tailorable properties is increasingly relevant in engineering.
