Chemists at the School of Science of the Hong Kong University of Science and Technology (HKUST) have recently made ...

Teaching the VSEPR (valence shell electron-pair repulsion) model can be a tedious process. Traditionally, Lewis structures are drawn and the number of “electron clouds” (groups) around the central ...

Lewis structures are fundamental to learning chemistry, yet many students struggle to develop a complex understanding of its meaning and uses. Writing-to-Learn supports students in developing a deeper ...

Researchers from the Institute of Modern Physics (IMP) of the Chinese Academy of Sciences (CAS), together with collaborators from the Instituto Tecnológico de Aeronáutica in Brazil and Iowa ...

The coating permeability allows it to penetrate deep into the concrete, creating an effective barrier that minimises external chloride salt intrusion. This synergistic effect surpasses ...
