Researchers at the University of Wisconsin-Madison have discovered a new way to speed up the process of discovering new high-performance polymers. By using machine learning and molecular dynamics simulations, they have discovered several promising polyimides out of a field of 8 million candidates. Polyimides are commonly used in the aerospace, automobile and electronics industries for

A team of Chinese scientists from the University of Science and Technology of China (USTC) has developed a new catalyst for hydrogen evolution reaction (HER). The researchers have created a general strategy for the synthesis of ten single-atom doped CoSe2-DETA (DETA = diethylenetriamine) nanobelts. The team has optimized the hydrogen evolution reaction (HER) activity of

Researchers from TUD Dresden University of Technology have discovered an innovative synthesis method for the production of phosphorus-containing chemicals. The new method has been published in the scientific journal, Nature Synthesis. The research team, led by Professor Jan J. Weigand, has developed a sustainable process that requires only two process steps, resulting in significant time

Chemistry faces big challenges in controlling chemical reactions to create new products. This development has a significant impact on the industry, as it reduces waste in the manufacture of construction materials and improves the production of catalysts for speeding up chemical reactions. Polariton chemistry, which uses the tools of chemistry and quantum optics, has seen

Researchers at Eindhoven University of Technology have developed a new catalyst that can convert toxic carbon monoxide into carbon dioxide gas even at room temperature. The so-called three-way catalytic converter in a car’s exhaust system only works correctly when the exhaust gases are several hundred degrees Celsius. As a result, toxic carbon monoxide remains in

Scientists are becoming creative in engineering yeast or bacteria to produce chemicals that are useful. A group of chemists from different universities has a more ambitious goal of retooling the cell’s polypeptide manufacturing plants and modifying the ribosomes that spin amino acids into protein to produce polymer chains that are more elaborate. The goal of

Class I major histocompatibility complex (MHC-I) proteins are crucial in the immune system of all jawed vertebrates. They showcase peptide fragments of proteins present inside the cell on the cell surface, displaying them to the immune system. This allows the immune system to scan the body for foreign or toxic antigens. When foreign peptides are

A group of counterfeiters was recently caught producing fake luxury jewelry items by pouring molten metal into molds produced from the original jewelry. In a similar way, a template scaffold can produce an endless amount of molecular crystals of any shape or form. Researchers at Pohang University of Science and Technology (POSTECH) have used this

A new study conducted by researchers at Stanford University, the National Institute of Standards and Technology (NIST), the University of Maryland, and Colorado State University has found a previously unknown reason why foods cooked at high temperatures, such as red meat and deep-fried foods, elevate the risk of cancer. The research discovered that the DNA

Polymers have become indispensable in our daily lives, from clothing to electronic devices, but their inability to decompose easily has led to long-term environmental challenges. The development of sustainable polymers with a more sustainable life cycle is crucial to help address this environmental crisis. However, the development of biodegradable polymers remains limited by current biodegradation

A new method has been developed to map the optical absorption of molecules in the electric field of an ultrashort terahertz pulse, which helps determine the strength and dynamics of electric interactions. Molecules in water and other polar media are subject to strong electric forces that originate from their liquid environment. At ambient temperature, this

A group of scientists and engineers, including researchers from The University of Texas at Austin, have developed a new class of materials that can absorb low energy light and turn it into higher energy light. The group achieved this through combining ultra-small silicon nanoparticles and organic molecules, closely related to those used in OLED TVs.

Urban populations face critical issues of food waste and food-borne diseases, which contribute to greenhouse emissions and environmental costs. Food spoilage remains the primary cause of such waste. Therefore, it is essential to improve the processing, transportation, and preservation of food in line with current technological advancements. Unfortunately, present monitoring processes are inefficient, expensive, and

Scientists from Radboud University have created synthetic molecules that mimic the behavior of real organic molecules. A team of researchers led by Alex Khajetoorians and Daniel Wegner have developed the ability to simulate the behavior of real molecules by using artificial molecules. This breakthrough allows properties of molecules to be tweaked in ways that were

The activation of G protein-coupled receptors (GPCRs) is responsible for relaying molecular signals in the body, which affects various bodily processes. It is estimated that around one-third of existing drugs work by controlling the activation of this protein. However, drugs that activate multiple signaling pathways rather than a specific target pathway can lead to adverse
