Researchers embedded a sulfonate-functionalized covalent organic framework in a fluorinated polymer electrolyte, creating ordered pathways that increased sodium-ion conductivity to 1.2 mS cm?¹ at 30 °C. The composite supported long-lived sodium-metal cycling and retained 87.3% capacity after 488 cycles in a 1 Ah solid-state pouch cell.
PicoQuant, a world leading company in photoluminescence instrumentation, announces the launch of Solira, a new microscope for time-resolved photoluminescence (TRPL) measurements and advanced materials characterization.
The future of scientific discovery will use all the technological tools at humanity's disposal, and no scientific field is better equipped to do so than autonomous discovery, which combines robotics and artificial intelligence (AI).
Researchers developed a thiourea-derived surface treatment that combines a sub-nanometer sulfur-rich coating with a spinel-like layer to protect lithium-rich manganese oxide cathodes and accelerate lithium-ion transport. In laboratory solid-state half-cells, the modified cathode delivered 220.2 mAh g?¹ and retained approximately 97% of its capacity after 600 cycles at 1 C.
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.
