Scientists have discovered a faster, more sustainable method for making metal-encapsulated covalent organic frameworks (COFs), materials that have the potential to play a crucial role in catalysis, energy storage, and chemical sensing.
University of Wisconsin–Madison biochemists have developed a new, efficient method that may give first responders, environmental monitoring groups, or even you, the ability to quickly detect harmful and health-relevant substances in our bodies and environments.
Covalent organic frameworks (COFs) are less stable as catalysts than previously thought but remain highly active. COFs are promising designer catalysts, for example for the sustainable production of chemicals and fuels. Their properties can be adjusted very specifically to catalyze a desired reaction based on their precise tunability, both in terms of molecular structure and chemical compositions.
A collaborative effort by the research groups of Professor Haruhiko Fuwa from Chuo University and Professor Masashi Tsuda from Kochi University has culminated in the structure elucidation and total synthesis of anticancer marine natural products, iriomoteolide-1a and -1b. These natural products were originally isolated from the marine dinoflagellate collected off the Iriomote Island, Okinawa, Japan.
Harvesting water from the air and decreasing humidity are crucial to realizing a more comfortable life for humanity. Water-adsorption polymers have been playing a key part in atmospheric water harvesting and desiccant air conditioning, but desorption so that the polymers can be efficiently reused has been an issue.
Unsymmetrical ureas can form multiple stable hydrogen bonds with proteins. Since drugs containing urea functional groups display unique biological activities when interacting with their targets, they play an important role in drug development and medicinal chemistry. As a result, finding efficient methods for synthesizing unsymmetrical ureas is important to these fields.
Researchers at the University of Virginia School of Engineering and Applied Science have developed a new polymer design that appears to rewrite the textbook on polymer engineering. No longer is it dogma that the stiffer a polymeric material is, the less stretchable it has to be.
Scientists are calling for changes to chemistry textbooks after discovering a fundamental aspect of structural organic chemistry has been incorrectly described for almost 100 years.
A team of researchers has developed a microfluidic system to tackle antimicrobial resistance (AMR). Operating at the picoliter scale, the system condenses billions of bacterial cells into a confined microenvironment, accelerating the experimental evolution of resistance.
A study that harnesses a pioneering 3D printing technique to create tiny human blood vessel structures could eventually help end the use of animals to test new drugs.
Biochemists from the National University of Singapore (NUS) have discovered a new subclass of trifunctional enzymes in gram-positive bacteria, which play a critical role in the biosynthesis of an antimicrobial lanthipeptide.
A research team at the Institute of Materials Chemistry at TU Wien, led by Professor Dominik Eder, has developed a new synthetic approach to create durable, conductive and catalytically active hybrid framework materials for (photo)electrocatalytic water splitting. The study is published in Nature Communications.
Imagine—it's the mid-1800s, and you're riding your high-wheeled, penny-farthing bicycle down a dusty road. Sure, it may have some bumps, but if you lose your balance, you're landing on a relatively soft dirt road. But as the years go by, these roads are replaced with pavement, cobblestones, bricks or wooden slats. All these materials are much harder and still quite bumpy.
Researchers have published a comprehensive review in Chemical Reviews on electron density-based methods.
Nearly all technology today—from cellphones to computers to MRI scanners—contains rare earth elements (REEs). The global market for REEs is predicted to reach $6.2 billion (USD) this year and $16.1 billion (USD) by 2034.
