Dr. Chunhua Liu proposes a new electric magnetic-geared (EMG) machine, which artfully incorporates the magnetic gear into an outer-rotor inserted permanent-magnet machine.
In January 2017 the Hong Kong Government released its Climate Action Plan 2030+, giving details of targets to reduce the carbon intensity of the economy by 65-70% by 2030.
Prof Michel A Van Hove, Director of the Institute of Computational and Theoretical Studies and Head of Physics at the Hong Kong Baptist University, awed the audience at the SEE Colloquium with the design of molecular machines.
Prof Van Hove, an authority in the field of surface science, explained the working principles of molecular vehicles. Measuring just in the nanoscale, these molecular machines were assembled carefully and painstakingly by covalently linking organic molecules to form the engine, chassis and the wheels.
The research team, led by Dr Walid Daoud, Associate Professor in CityU’s School of Energy and Environment, has combined two energy conversion concepts, namely piezoelectric and triboelectric effects, to create a hybrid system.
The rapid development and economic prowess that we have enjoyed in the last century was built on the backbone of fossil energy. From heating to manufacturing, mass transportation to lighting bulbs, and even powering our remote control, the energy was sourced, directly or indirectly, from crude oil, coal or natural gas which chemical energy was converted to electricity.
Dr. Sam H.Y. Hsu, Assistant Professor, has developed a general method for re-solving the trade-off between effciency and stability of metal–insulator–semiconductor photoelectrodes by employing dielectric breakdown for solar fuel application published on Nature Materials this year. This work has been featured on the front cover of the January 2017 Volume 16 No 1 issue of Nature Materials, http://www.nature.com/nmat/journal/v16/n1/covers/index.html. Dr. Sam collaborated with Researchers in Microelectronic Research Center, Department of Electrical and Computer Engineering, The University of Texas
The groups of Dr. W.Y. Teoh and Dr. Denis Yu reviewed the advancements in functionalized graphene composites and their applications in Energy and Environment. The work was one of the most read in Chem. Mater. in the past year.
Dr. Sam Hsu demonstrates a novel liquid junction solar cell based on metal halide perovskite p-MeNH3PbI3 photocathode. The work makes use of organic redox mediators that is compatible with the fragile perovskite absorber layer.
