Researchers developed a light-responsive spiropyran and multi-walled carbon nanotube hybrid that accelerated Bisphenol A degradation under simulated solar irradiation and generated reactive oxygen species linked to pollutant breakdown. The catalyst also reduced cytotoxicity in MCF-7 cell tests and retained its crystalline structure across four reuse cycles, though its degradation efficiency declined gradually.
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.
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.
Laboratory press manufacturer Carver is launching its redesigned AutoPellet RP Press Series, featuring a new enhanced color touchscreen interface, ergonomic design, and a smaller footprint.
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.
Xianglan Bai illustrates her development of biobased carbon fiber with two beakers in researchers' hands.
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.
A new $2.7 million industry-led project will help establish the sovereign capability Australia needs to manufacture critical metal components for defense, maritime and medical applications.
Researchers developed an entirely rare-earth-free regenerator system for 4 K Gifford-McMahon cryocoolers by combining MnNb2-xTaxO6 with CuFe1-xAlxO2 to exploit their complementary low-temperature heat capacities. The best configuration delivered 0.163 W at 4.2 K, about 40% more cooling capacity than the CFAO-based regenerator and 73% of the performance of benchmark HoCu2 under equivalent conditions.
