This review shows how grain refinement, dynamic recrystallization, phase transformations, and controlled precipitation enable selected medium- and high-entropy alloys to sustain extreme elongation at elevated temperatures. The authors identify scalable processing, oxidation resistance, cost, recyclability, and validation in engineering-scale components as key barriers to industrial superplastic forming.
Researchers combined density functional theory, machine-learning-enhanced transition-state calculations, and microkinetic modeling to screen 12 Ni-based ternary alloys for nitric oxide reduction under representative aircraft exhaust conditions. The analysis identified four promising candidates, with Ni-Cr-Pt offering the strongest predicted balance of catalytic activity, stability, carbon resistance, and material cost, although experimental validation is still required.
Tescan, a pioneer in electron microscopy, announces the successful completion of its full acquisition by Shimadzu Corporation. As of July 7th, Tescan officially becomes a member of the Shimadzu Group, marking an important milestone in the company's continued growth and evolution.
Long-term carbonate mineralization helped preserve a 2nd-century Roman concrete sample from Hadrian’s Villa by forming calcite cements that filled pores, fractures, and microcracks. The study shows that calcite, alongside smaller amounts of C-A-S-H from volcanic aggregate reactions, contributed to the material’s millennial durability.
Researchers at Argonne National Laboratory have developed a framework, ChemGraph, that uses artificial intelligence to help nonexperts access computational chemistry expertise.
Researchers converted pine resin-derived rosin into a thermoplastic, mesophase-forming pitch that can be graphitized into high-quality bulk graphite. The study shows how molecular restructuring of renewable terpenes could reduce reliance on fossil-derived pitch for graphite manufacturing.
This review explains how soft materials, scalable manufacturing, energy-efficient hardware, and AI are converging to create smarter wearable systems for physiological monitoring and human-machine interaction. It argues that real-world deployment will depend on cross-layer co-design, durable skin interfaces, efficient edge computing, and standardized testing under everyday conditions.
Researchers introduced intrinsically nonlocal metamaterials, demonstrating that nanoscale semiconductor layering can shape a material’s intrinsic charge-carrier response and thereby determine how light propagates. The study combines theory, simulations, and room-temperature infrared experiments to reveal electromagnetic modes that conventional local models cannot explain.
Summer has hit the Northern Hemisphere, bringing a roller-coaster of temperature and humidity swings to many areas.
The review finds that biodegradable plastics could help reduce persistent plastic pollution, but only if paired with lower plastic use, better recycling, clear certification, and proper disposal infrastructure. It highlights major barriers, including high costs, inconsistent real-world degradation, environmental trade-offs, and limited waste-management systems.
