Cobalt ions, not covalent organic frameworks themselves, drive catalytic activity, study finds

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.

Integrated approach elucidates the long-sought structure of a natural powerful anticancer product

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 air: Copolymer solution uses water-loving differential to induce desorption

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.

Scientists synthesize unsymmetrical ureas using non-phosgene method

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.

Team solves a nearly 200-year-old challenge in polymers to offer independent control of stiffness and stretchability

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.

New hybrid catalyst developed for clean oxygen production

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.

From using plant rinds to high-tech materials, bike helmets have improved significantly over the past two centuries

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.
