In the era of smart cities and amid the global outbreak of Covid-19, connecting through the internet is getting more important than ever. Researchers have been working day and night on advancing the optical data transmission network to address the demand for faster transmission speed. An international research team has developed a new technology that is equipped with a special chip made by a scientist from City University of Hong Kong (CityU). The team broke the spectral efficiency world record for optical data transmission with a single integrated photonic chip. This allows the transmission speed as fast as downloading 1,000 high-definition movies in less than a second!

Understanding the microscopic origin of different physical properties of solids is of fundamental importance for condensed-matter physics and for materials applications. Yet, there is still a lot of unknowns in amorphous materials due to their disordered atomic structure. Recently, with the state-of-the-art neutron scattering instrumentation and molecular dynamic simulations, an international research team, led by physicists from City University of Hong Kong (CityU), has demonstrated the existence of high-frequency transverse phonons in metallic glass for the first time. Their findings also suggest that the atomic structure correlates with its atomic dynamics, providing new insight for understanding the atomic structure-dynamics relationship in disordered materials.

Research at Kanazawa University as reported in Scientific Reports demonstrates atomic force microscopy imaging that gets around the challenges of exciting very small cantilevers at their high megahertz resonance frequencies. The approach accomadates wide frequency bandwiths, and is applicable for photosensitive materials in a wide range of liquids.

A hemispherical vanadium oxide cluster has a cavity that can accommodate a bromine molecule. It was found that a bromine molecule trapped in the cavity was polarized and that an alkane molecule like pentane, butane and propane could be brominated with the bromine molecule in the cavity with a selectivity differing from ordinary bromination. The present findings are expected to be useful for polarization of small molecules and design of highly functional catalysts.

Calculated lattice thermal conductivity of MgSiO3 postperovskite (PPv) and bridgmanite (Brg) under the Earth’s lowermost mantle conditions
13 Feb 2020
Lattice thermal conductivities of MgSiO3 bridgmanite and postperovskite (PPv) phases under the Earth’s deepest mantle conditions were determined by quantum mechanical computer simulations. We found a substantial increase in the conductivity associated with the phase change. This indicates that the PPv phase boundary is the boundary not only of the mineralogy but also the thermal conductivity. The effect of anisotropy on the conductivity of PPv in the heat transport properties at the lowermost mantle was also found to be minor.
