Children’s interest in, and competence perceptions of, mathematics are generally quite positive as they begin school, but turn less positive during the first three years. This is shown by a recent study exploring the development of children’s motivation for mathematics during the early school years, and how that development is associated with their mathematics competence. …

Hydrogen stored in hydrogen boride sheets can be efficiently released electrochemically, report scientists. Through a series of experiments, they demonstrated that dispersing these sheets in an organic solvent and applying a small voltage is enough to release all the stored hydrogen efficiently. These findings suggest hydrogen boride sheets could soon become a safe and convenient …

Semiconductors are ubiquitous in modern technology, working to either enable or prevent the flow of electricity. In order to understand the potential of two-dimensional semiconductors for future computer and photovoltaic technologies, researchers investigated the bond that builds between the electrons and holes contained in these materials. By using a special method to break up the …

Highly reducing or oxidizing photocatalysts are a fundamental challenge in photochemistry. Only a few transition metal complexes with Earth-abundant metal ions have so far advanced to excited state oxidants, including chromium, iron, and cobalt. All these photocatalysts require high energy light for excitation and their oxidizing power has not yet been fully exploited. Furthermore, precious …
