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

This work presents the first room temperature operation of GaAs based ridge waveguide semiconductor lasers containing lithographically defined InGaAs quantum dots as the active region. Semiconductor ...

A new blue fluorescent molecule set new top emission efficiencies in both solid and liquid states, according to a University ...

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 ...
