A polymer science revelation about how liquid mixtures separate could have major implications for human health, metabolism and disease, new research indicates. In a brief report published in the Proceedings of the National Academy of Sciences, University of Chicago Pritzker School of Molecular Engineering (UChicago PME) Professor Matthew Tirrell and Freie Universität Berlin Professor Matthias Ballauff revealed previously overlooked factors at play in the separation of charged polyelectrolyte polymers in water, challenging assumptions that have dominated the field since the 1950s.
What, exactly, is a plant made of? Scientists have a good understanding of the essential nutrients plants need to grow. But what plants need and what they contain are not necessarily the same.
New research suggests that replacing polyethylene (PE) packaging with paper, glass, aluminum or steel often does not reduce environmental impacts across a product's life cycle.
Hydrogen peroxide (H₂O₂) is a versatile chemical feedstock whose industrial production relies predominantly on an energy-intensive process with a substantial environmental footprint. One alternative is to produce it using a catalyst activated by light. In an international research project involving the Max Planck Institute of Colloids and Interfaces, researchers have now developed a synthesis strategy that allows them to precisely control the spatial arrangement of ions in a carbon nitride. The resulting photocatalyst is three times as efficient as conventional green production methods. The findings have been published in Advanced Materials.
A technique for detecting potentially harmful metals in regenerated cellulose food packaging is discussed in the International Journal of Environment and Pollution. The new tool can be used for safety assessments of materials increasingly used as alternatives to conventional plastics.
In a study published in Nature Communications, researchers from The University of Manchester and Lancaster University have isolated and characterized uranocenium, the positively charged form of a landmark uranium compound called uranocene. The work shows that this long-sought molecule is stable, and that it behaves in a way that challenges how chemists usually think about bonding in heavy elements.
Potatoes could hold the key to making better gluten-free plant-based meat, according to a new study.
A review by Tohoku University researchers identifies key molecular features that could guide the development of more effective materials for removing PFAS from water. The study is published in the journal ACS Materials Au.
The new RFD4-Proteina unified generative model for protein design—created by the Institute for Protein Design (IPD) in collaboration with NVIDIA—uses advanced AI to generate entirely new protein sequences and structures, achieving computational design success rates five to 10 times higher than previous models and generating candidates five to 10 times faster.
Researchers at the University of St Andrews have identified the first examples of a new class of advanced organic semiconductor materials that could one day be used as bioimaging agents, opening up new possibilities for deep-tissue imaging. The study, published in Nature Communications, was led by the Zysman-Colman group in the School of Chemistry at the University of St Andrews in collaboration with the Pal group at Durham University.
From a rigid molecular pair to flexible assemblies with moving domains, the enzymes that build sugar chains display strikingly different behaviors.
Researchers at National Taiwan University (NTU), working across the College of Engineering, College of Medicine and National Taiwan University Hospital (NTUH), have developed a new method for producing aerogels, introducing what they describe as the world's first purely gaseous-born aerogel fabrication platform. The study is published in Nature Communications.
A material thinner than a human hair may foster faster computing devices that demand less energy and store more data, according to a multi-institutional team led by researchers in the Penn State College of Earth and Mineral Sciences.
The humble amino acid glycine—the simplest of all amino acids—is everywhere. The human body produces it, and it helps make up our skin, bones and ligaments. It's found in meats like beef and has even been discovered in comets returned from outer space.
In biology, a group of enzymes called 2-oxoglutarate-dependent oxygenases is responsible for catalyzing a wide range of reactions that play a role in everything from how genetic code is used by cells to the synthesis of antibiotics.
