A team led by Kenneth Merz, Ph.D., Staff at Cleveland Clinic's Center for Computational Life Sciences, showed how quantum computers can be used for investigating how molecules act in aqueous solutions.
A research team from Skoltech, AIRI, Tomsk Polytechnic University, and Sber has proposed and tested an approach to predicting the modification of material properties. Artificial intelligence models that were pre-trained on a small amount of data enabled a significant increase in the calculation of the formation energies in possible configurations of higher tungsten boride doped with other metals.
A research team led by the Department of Energy's (DOE) Lawrence Berkeley National Laboratory (Berkeley Lab) designed and fabricated catalysts that can increase the speed of carbon monoxide oxidation by nine times. Carbon monoxide oxidation is an important reaction used in numerous chemical industry and environmental cleaning applications. The cutting-edge fabrication approach involved making precise, atomic-level changes in catalysts to create new, performance-boosting chemical properties.
Large, hard-to-access equipment and high temperatures: Foundries are home to extreme conditions. Working with liquid metal requires flexibility and resilience in humans and machines alike. With an eye to this challenging environment, a team of researchers from Fraunhofer IZFP was tasked with developing a new measuring system for customers from the aluminum industry to detect contamination in molten metal—an important tool during the production process.
Weight-loss drugs like Ozempic and Wegovy are used by more than 15 million adults in the U.S., or 4.5% of the population. Despite their effectiveness, they have drawbacks. Their effect may not last after discontinuing use, and side effects including osteoporosis and muscle loss have raised concerns about long-term harms. They also induce nausea, which can make it difficult to stay the course of treatment.
A new bio-based hot glue derived from a byproduct of the wood pulp industry beats traditional epoxy resins and commercial hot-melt glues in terms of adhesive performance.
Sarin (isopropyl methyl fluorophosphonate) is an organophosphorus nerve agent regulated by the Convention on the Banning of Chemical Weapons. It can enter the body through the respiratory system, skin, or eyes, paralyzing the central nervous system by inhibiting acetylcholinesterase, which can lead to death. Therefore, rapid and sensitive detection of trace sarin is vital for safety and environmental protection.
As demand for advanced polymeric materials increases, post-functionalization has emerged as an effective strategy for designing functional polymers. This approach involves modifying existing polymer chains by introducing new chemical groups after their synthesis, allowing for the transformation of readily available polymers into materials with desirable properties.
When visiting the dentist, you might remember being poked and prodded by a thin metal instrument to check your teeth and gums. This technique, called periodontal probing, is used to look for signs of gum disease. Now, researchers publishing in ACS Sensors report a toothbrush-shaped ultrasound transducer that can provide a less invasive screening for gum disease. In proof-of-concept demonstrations on animal tissues, the device produced measurements similar to those of a manual probe.
Chronic stress can lead to increased blood pressure and cardiovascular disease, decreased immune function, depression, and anxiety. Unfortunately, the tools we use to monitor stress are often imprecise or expensive, relying on self-reporting questionnaires and psychiatric evaluations.
In biology, enzymes have evolved over millions of years to drive chemical reactions. Scientists from the Max Planck Institute for Dynamics and Self-Organization (MPI-DS) have now derived universal rules to enable the de novo design of optimal enzymes.
Researchers have isolated two novel bis-β-triketone hybrids, Corymbinols A (1) and B (2a/2b), from the fruits of Corymbia citriodora. Corymbinol A demonstrated a 31% inhibition of cuproptosis in HepG2 cells at a concentration of 20 μM, suggesting its potential as a non-toxic therapeutic option against liver cancer.
A study by the Leibniz Institute for Food Systems Biology at the Technical University of Munich shows that less bitter-tasting pea protein hydrolyzates can induce just as strong satiety signals in stomach cells as their more bitter counterparts.
They say a picture is worth a thousand words. But it takes millions of pictures to understand the intricate chemistry of an enzyme that helps break down sulfur, commonly found in fruits, vegetables, alcohol and gasoline, into the colorless gas most noted for its distinctive odor.
Zinc chromite (ZnCrOx) oxides coupled with zeolites (OXZEO) have shown great promise as the catalyst for the direct conversion of syngas into light olefins. However, identifying the specific active sites for this reaction remains elusive due to the structural complexity of the ZnCrOx composite oxides.
