A group of researchers at the University of Tokyo have spent years testing the limits of chemical bonds. And now, after years of work, they've finally explored an idea originally proposed in 1931: a ...

Researchers have developed a Bayesian learning model of chemisorption, or Bayeschem for short, aiming to use artificial intelligence to unlock the nature of chemical bonding at catalyst surfaces. A ...

The latest short science news items from C&EN. Open an introductory chemistry textbook. What is a covalent bond? A covalent bond occurs when atoms share electrons in a molecule. What is a hydrogen ...

Everything in the world is chemistry. All materials are composed of atoms, whose positively charged nuclei are surrounded by a greater or lesser number of negatively charged electrons. 'A covalent ...

Illustration of intracluster bond formation, cluster containing two biomolecules, being exposed to UV light (left), causes a chemical bond forming between the two molecules (center), resulting in a ...

Chemistry students the world over are familiar with covalent bonds and hydrogen bonds. Now a study has revealed a strange variety of bond that acts like a hybrid of the two. Its properties raise ...

The carbon-hydrogen bond -- 2/3 of all bonds in hydrocarbons -- has defied chemists' attempts to open it up and add new chemical groups. A team has now cracked the strongest of C-H bonds, those on a ...
