Single atomic defect is the smallest structural unit of solid material. The construction of devices based on single defect can reach the limit of miniaturization of semiconductor devices. In the past decades, the creation and manipulation of single defects in semiconductors opened a new research field, and could be used to physically realize qubits of solid-state quantum computation through spin or electron charge. Most interest have focused on the studies of spin quantum computing. However, the spin manipulation need an optical and magnetic field. On the contrary, multiple charge states can be written and read using only an electric field, which will result in a more compact device size and compatibility with modern electronic technology.

From the biggest bridges to the smallest medical implants, sensors are everywhere, and for good reason: The ability to sense and monitor changes before they become problems can be both cost-saving and life-saving.
To better address these potential threats, the Intelligent Structural Monitoring and Response Testing (iSMaRT) Lab at the University of Pittsburgh Swanson School of Engineering has designed a new class of materials that are both sensing mediums and nanogenerators, and are poised to revolutionize the multifunctional material technology big and small.
Scientists at Tokyo Institute of Technology (Tokyo Tech) created a novel type of material that combines the structural flexibility of van der Waals materials with the endless tuning possibilities of high-entropy alloys. In their paper, they explore the properties of these new materials and the many promises they hold in electronics applications.

The Water Oxidation Reaction (WOR) is one of the most important reactions on the planet since it is the source of nearly all the atmosphere s oxygen. Understanding its intricacies can hold the key to improve the efficiency of the reaction. Unfortunately, the reaction s mechanisms are complex and the intermediates highly unstable, thus making their isolation and characterisation extremely challenging. To overcome this, scientists are using molecular catalysts as models to understand the fundamental aspects of water oxidation - particularly the oxygen-oxygen bond-forming reaction.
For the first time, scientists in ICIQ s Lloret-Fillol group, who are minutely studying WOR, have isolated and fully characterised an elusive intermediate generated after the oxygen-oxygen bond formation event - the reaction s rate-determining step. The work, an international effort led by ICIQ in collaboration with University of Groningen (The Netherlands) and Synchrotron SOLEIL (France), has
