Through the weak nuclear force, one quark flavor can transmute into another. However, current data and theory indicate that the probabilities of quark flavor transmutation do not add up to 100%, as predicted by the Standard Model of Particle Physics. To understand whether this is due to physics beyond the Standard Model or underestimated uncertainties, nuclear theorists laid out a new framework needed to extract the up-down quark flavor mixing with a precision of a few parts in ten thousand from certain nuclear beta decays.

Proof-of-concept work uses unique, safe particles to remove microplastics in a single cycle.

In-depth chemical analysis of three key 12th century medieval bronze doors by Barisanus of Trani uncovers which is the oldest and reveals how they were made

Every year, millions of tires end up in landfills, creating an environmental crisis with far-reaching consequences. In the United States alone, over 274 million tires were scrapped in 2021, with nearly a fifth of them being discarded into landfills. A study led by Dr. Aleksandr Zhukhovitskiy, an assistant professor in the department of chemistry at UNC-Chapel Hill, has pioneered a technique for breaking down this rubber waste and transforming it into valuable precursors for epoxy resins. This technique offers an innovative and sustainable alternative to traditional recycling methods while significantly reducing rubber waste in landfills.

University of Texas at Dallas developed a new theory to explain heat transfer on advanced surfaces, which they outline in an article published online March 13 in the physical science journal Newton.

The theory is critical to the researchers’ work to develop innovative surfaces for applications such as harvesting water from air without electricity.

Oxford Chemistry researchers have developed a method to destroy fluorine-containing PFAS (sometimes labelled ‘forever chemicals’) while recovering their fluorine content for future use. The results have been published today (26 March 2025) in Nature.
