Yale chemists have synthesized a unique class of anticancer molecules from bryozoans for the first time, marking a major advance in the field of synthetic chemistry. By employing a novel approach that combines strategic chemical processes and advanced structural determination techniques, the team has opened new possibilities for cancer treatment research.Almost three decades ago, researchers identified a distinct group of anticancer compounds within bryozoans, a category of marine invertebrates native to tropical…

RoboChem is an autonomous benchtop platform for fast, accurate, and around-the-clock chemical synthesis. Credit: University of AmsterdamChemical researchers at the University of Amsterdam have created a self-operating chemical synthesis robot equipped with an AI-based machine-learning system, named ‘RoboChem’. This compact laboratory instrument surpasses human chemists in speed and precision, while also displaying a high level of ingenuity. As the first of its kind, it could significantly accelerate the chemical discovery…

Applying an electric potential causes a proton to transfer from a hydronium ion (at right) to an electrode’s surface. Using electrodes with molecularly defined proton binding sites, MIT researchers developed a general model for these interfacial proton-coupled electron transfer reactions. Credit: MITA key chemical reaction — in which the movement of protons between the surface of an electrode and an electrolyte drives an electric current — is a critical step in many energy technologies, including fuel cells and the…

I hope the former record-holders aren’t too cross: a team of researchers recently made the smallest, tightest knot yet known, landing themselves top spot in the Guinness Book of World Records.Modern Yet Retro | JBL Spinner BT ReviewThe knot is composed of 54 atoms, chained together and ensnared in a trefoil, the simplest nontrivial knot. The knot has no loose end; it is a continuous loop, passing through itself in mesmerizing arcs. The team’s work describing the self-assembled “metallaknot” was published in Nature…

On my commute to work today, I had the misfortune of being crammed into a narrow tube underground. But it could have been worse: I could’ve been squished into a single dimension. Alex Winter on His Character in Destroy All Neighbors That’s what recently happened to some krypton atoms in an Ulm University chemistry lab. Using transmission electron microscopy (or TEM), a team managed to squeeze the noble gas into a nanotube with a diameter 1/500,000th that of a human hair. In such a confined space, the atoms could not…

Scientists have accidentally tied the smallest and tightest knot ever, overtaking the top spot in the Guinness Book of World Records.The remarkable microscopic tangle contains just 54 atoms that twist around three times into an interlacing loop called a 'trefoil' knot, with no loose ends.This 'three-leaf clover' shape is the simplest of nontrivial knots, and it's fundamental to mathematical knot theory.In 2020, chemists in China trained a chain of 69 atoms to cross over itself three times to form the trefoil. Now,…

Scientists have developed CREATS, a novel technique for sequencing synthetic polymers, revolutionizing the understanding of how monomer arrangement influences material properties and enabling the design of polymers for specific applications. Credit: SciTechDaily.comSynthetic polymers, which are ubiquitous in modern life, include materials such as nylon and polyester fabrics, Teflon-coated cookware, and epoxy adhesives. On a molecular scale, these polymers consist of lengthy chains of monomers, the complexity of these…

MIT researchers have improved the stability of acenes, molecules with potential in semiconductors and light-emitting diodes. This breakthrough allows acenes to emit various colors and could advance their use in efficient solar cells and brighter, energy-saving screens.The molecules, known as acenes, could be useful as organic light-emitting diodes or solar cells, among other possible applications.Chains of fused carbon-containing rings have unique optoelectronic properties that make them useful as semiconductors. These…
