The Korea Research Institute of Standards and Science (KRISS, President Dr. Ho Seong Lee) has re-measured a key transition frequency of the strontium (Sr) atom for the first time in 88 years since 1938, using a photonic grating chip, and has established a new absolute frequency value with a measurement uncertainty reduced by more than 50 times.
A research team led by Dr. Kyung-Soo Kang and Dr. Hyun-Jun Lee from the Hydrogen Energy Research Division of the Korea Institute of Energy Research (KIER) has developed novel Ni/Co-based heterostructure water electrolysis electrodes that deliver superior hydrogen production efficiency compared to conventional noble-metal electrodes.
It's a typical evening at the bar, glasses clinking and conversation humming, until an unusual sight warrants a double take. At a nearby table, a young man in a T-shirt and jeans —and safety goggles and gloves —appears to be casting metal.
The Department of Energy's (DOE) Oak Ridge National Laboratory (ORNL) has joined BioMADE, a national institute focused on advancing manufacturing using biological systems in the United States, strengthening connections between ORNL research, industry needs and pathways to commercial-scale production of new chemicals and materials.
Researchers demonstrated a proof-of-concept method for machining silicon with a single 30-femtosecond extreme ultraviolet pulse, producing reproducible micrometer-scale craters with sub-micrometer widths under selected conditions. Simulations captured the dose-dependent trend but underestimated crater size, while the experiments point to possible future uses in maskless semiconductor processing and photomask fabrication.
Indium Corporation®, an industry leader in innovative materials solutions for semiconductor packaging and electronics assembly, received a Mexico Technology Award in the solder paste category for its Indium12.9HF, a no-clean, halogen-free solder paste designed to meet the growing challenges of high-density, fine-pitch assemblies.
Researchers developed a terbium(III) complex with salicylic acid hydrazide that produced predominantly green luminescence and was tested for anti-counterfeiting inks, latent fingerprint visualization, and several laboratory bioactivity measures. Under the study conditions, the material showed durable visible luminescence, resolved fingerprint details across varied surfaces, and produced preliminary antioxidant, antimicrobial, cytotoxic, and a-glucosidase-inhibitory results that require further validation.
Scientists have found a way to use defects in crystals to engineer stronger materials, according to a new study.
A new technique to partially embed different types of nanoparticles into the surface of polymer materials such as plastics has been developed by University of Leicester scientists.
Researchers developed a pre-embedded solid-solid redox mediation strategy that mixes sulfur and iodine at the nanoscale inside mesoporous carbon to accelerate sulfur conversion in all-solid-state lithium-sulfur batteries. The iodine redox chemistry enabled fast charging, long cycle life, and strong performance at higher active-material loadings across several sulfide solid electrolytes.
