ENERGY
Researchers at LG Energy Solution and Seoul National University secured a key technology that can significantly improve the stability of next-generation lithium manganese-rich batteries. They identified factors contributing to gas generation and capacity degradation during charging and discharging and developed optimal operating conditions for large-format cells.
Researchers identify cause of artifacts in battery nanoscale analysis(opens in new tab)
KAIST researchers identified the cause of a measurement artifact in nanoscale battery analysis that can be mistaken for actual ion transport. The team also proposed a method for effectively reducing this artifact.

New study unlocks stronger, cheaper 3D printing resins with modified mineral(opens in new tab)
Researchers successfully reinforced photosensitive resins using a common, low-cost mineral called acicular wollastonite. By modifying the surface of these needle-shaped particles, the researchers overcame key limitations of standard resins, such as brittleness and shrinkage during curing.
Low-carbon concrete put to the climate test(opens in new tab)
Researchers at ETH Zürich developed a new approach that enables the service life of reinforced concrete to be predicted based on weather conditions. This approach assesses the service life more realistically and thus could promote the wider use of low-carbon concrete in construction.

Temperature: A new knob for topological properties of materials(opens in new tab)
Researchers led by Shanghai Institute of Ceramics of the Chinese Academy of Sciences found that increasing temperature weakens spin-orbit coupling in the topological insulator Bi2Se3, driving a transition to a normal insulating state. The findings suggest that temperature could serve as a new “knob” for controlling the topological properties of materials.
Engineers create a world-first in floating titanium(opens in new tab)
Researchers led by RMIT University created a strong and lightweight titanium material that floats in water and withstands seawater exposure. The material could be a promising new material for marine infrastructure.
Researchers create niobium-based polar wurtzite nitride semiconductor(opens in new tab)
Researchers at Tokyo University of Science, the University of Tokyo, and Mie University achieved the first successful epitaxial growth of single-crystalline polar wurtzite NbAlN thin films on gallium nitride substrates. The material more than triples the interfacial electron density in a gallium nitride heterostructure.
