https://phys.org/chemistry-news/materials-science/ en-us The latest news on chemistry and materials science Look closely at Hokusai's The Great Wave off Kanagawa, one of Japan's most iconic masterpieces. The brilliant white of the waves, snow on Mount Fuji and clouds above contain no white pigment. Instead, their whiteness comes from the way light scatters off the unprinted fibers of the washi paper itself. https://phys.org/news/2026-09-white-nature-sustainable-repellent-materials.html Polymers Wed, 09 Sep 2026 11:00:31 EDT news708168421 Drug discovery has traditionally followed the "rule of 5," which identifies chemical properties generally associated with good absorption of orally administered drugs, including a molecular weight below 500 daltons (Da). However, some pharmaceutical compounds fall outside these guidelines. Known as beyond rule of 5 (bRo5) molecules, these compounds can have larger, more complex structures while still exhibiting strong therapeutic activity and favorable pharmacological properties. Their size and structural complexity, however, make it difficult to characterize them using conventional methods, particularly when very small quantities are available. https://phys.org/news/2026-09-crystalline-sponge-reveals-large-molecules.html Analytical Chemistry Tue, 08 Sep 2026 17:00:07 EDT news708097381 What if the key to making stronger, more sustainable plastics isn't changing their ingredients, but rearranging their molecules? Virginia Tech researchers have put that idea to the test, creating degradable polymers with a new molecular architecture that combines properties often difficult to achieve in one material: strength, toughness, flexibility and the ability to block oxygen. https://phys.org/news/2026-09-rearranged-polymer-chains-degradable-materials.html Polymers Tue, 08 Sep 2026 05:00:01 EDT news707994742 Copper has been knocked off the top of a stability ranking it had dominated for decades. Without altering the atoms directly bonded to the metal, a KAIST research team reversed the longstanding trend in which copper generally forms the most stable complexes by tuning only the weak hydrogen bonds in its surrounding environment. The findings, which appear in the Journal of the American Chemical Society, could open new avenues for selective metal separation and recognition, as well as catalyst design. https://phys.org/news/2026-09-weak-hydrogen-bonds-dethrone-copper.html Analytical Chemistry Mon, 07 Sep 2026 16:00:01 EDT news708004262 A common blue pigment could help turn carbon dioxide (CO₂) from an industrial waste product into a useful fuel.

The immobilized chains make them hard and stiff but also brittle, causing them to fracture when stretched. One promising strategy for overcoming this trade-off is to incorporate ionic groups whose reversible electrostatic attractions form physical crosslinks that improve toughness while maintaining stiffness. https://phys.org/news/2026-09-soft-crosslinking-strategy-brittle-glassy.html Polymers Fri, 04 Sep 2026 13:00:24 EDT news707738941 Patents are far more than legal documents protecting intellectual property. They are a vast source of scientific information about chemicals under development, often years before they appear in products or in the environment. That makes patents a valuable data source for early warning systems (EWS), which authorities use to identify potentially hazardous chemicals before they become a threat to human health and the environment. https://phys.org/news/2026-09-patent-ai-early-hazardous-chemicals.html Analytical Chemistry Fri, 04 Sep 2026 10:40:06 EDT news707734081 While studying the properties of hackmanite, researchers created a new material called davyne that changes color in the near-infrared region.

Activities such as the burning of fossil fuels for daily use, including electricity and transportation, and industrial applications release significant amounts of CO₂, and the gas enters the atmosphere. Researchers are now asking whether this road could have a roundabout. What if CO₂, which is at the center of the climate crisis, could be turned into something useful and put back into the industrial cycle? https://phys.org/news/2026-09-metal-2d-catalysts-extra-electrical.html Analytical Chemistry Wed, 02 Sep 2026 19:40:01 EDT news707583901 Copper roofs lose their reddish color over time because a pale green layer of copper oxide forms on their surface, protecting the roof from further corrosion for many years. But what exactly happens during the first steps of this process? Might it even be possible to stop it? This question has become increasingly urgent since copper containers have come to be regarded as one of the best options for storing nuclear waste. https://phys.org/news/2026-09-copper-oxygen-rich-early-oxidation.html Analytical Chemistry Wed, 02 Sep 2026 18:20:04 EDT news707582581 A good adhesive is unequivocally sticky. A great adhesive is sticky until you don't want it to be sticky anymore—a label on cardboard until it's time to recycle it. Medical tape on a cut until the wound heals.

It sounds like magic, but it could become reality with the help of so-called metamaterials. In the summer of 2026, some of the world's leading researchers in the field gathered in Umeå for a Nobel Symposium on metamaterials. The symposium was organized by Nicolò Maccaferri, associate professor at Umeå University. He studies these special materials, which over the past few decades have proven useful in fields ranging from telecommunications to medical technology. https://phys.org/news/2026-08-metamaterials-enable-invisibility-cloaks-thinner.html Materials Science Mon, 31 Aug 2026 10:20:07 EDT news707386676 Walk around any major fashion exhibition and you might get the impression that biofabricated materials are about to transform fashion.

Yet pushing organic light to these longer wavelengths usually causes a steep drop in efficiency. As the energy gap becomes smaller, molecular vibrations more readily turn excited-state energy into heat rather than light. https://phys.org/news/2026-08-molecular-makeover-brightens-nanometers.html Materials Science Thu, 27 Aug 2026 18:20:03 EDT news707050828 Researchers at the University of Osaka have developed a catalyst that uses mechanical vibration to convert carbon dioxide (CO2) into carbon monoxide (CO), an important chemical feedstock.
