The invention relates to an improved method for storing hydrogen in single-walled carbon nanotubes. Carbon nanotubes are dipped in hydrogen gas for absorption. The size of carbon nanotubes to be used depends on the density of hydrogen molecules, and generally, nanotubes of diameters from 0.5 to 1.2 .....

This novel antenna developed by CityU has high gain and wideband characteristics, and can be used as an element for constructing antenna arrays. Bandwidth and gain enhancement techniques cannot usually be implemented at the same time, since the structure may become very complicated or bulky. The inv.....

This invention presents light maximization method for LED systems. Derived from a general theory that links the photometric, electric and thermal behaviours of LED systems together, the method provides the rules to design LED systems with maximum light output. Its main contribution is to provide cle.....

The technology complements the on-chip monitoring of cellular reactions by exposing cells, isolated in a sandbag structure, to different concentrations of analytes or drugs in a one-step operation. The tapering microchannel structure controls the concentration and dosage of the analytes. Another maj.....
