Abstract:
A hybrid coating structure (500) includes a substrate (510) and a hybrid coating (100). The hybrid coating further includes a number of diamond-like carbon grains (110), each grains containing a number of superhard nano-particles (120) incorporated therein; and a number of corrosion-resistant nano-particles (130). The superhard nano-particles are comprised of a material selected from the group consisting of silicon carbide, titanium carbide, and titanium nitride. The corrosion-resistant nano-particles are comprised of a material selected from the group consisting of chrome and chrome nitride. A method for making a hybrid coating structure includes steps of: providing a substrate; producing carbon plasma, superhard particle plasma and corrosion-resistant particle plasma by a sputtering method; and depositing a hybrid coating.

A field emission element includes one supporting wire and at least one field emission layer coated or otherwise formed on an outer surface of the supporting wire. Each field emission layer includes a plurality of carbon nanotubes (CNTs) and is selected from a group consisting of CNT-polymer composites, CNT-glass composites and single-layer/multi-layer CNT films. A method for manufacturing the described field emission element is also provided. The method includes the steps of: (a) providing one supporting wire; (b) forming at least one field emission layer on an outer surface of the supporting wire; and (c) cutting the supporting wire, after forming the at least one field emission layer thereon, according to a predetermined length and then treating the at least one field emission layer on the supporting wire to form the field emission element.

Abstract:
A lithium ion battery includes a cathode (10) having a plurality of lithium-cobalt-nickel oxide nanoparticles, an anode (20) having at least one carbon nanotube array (22), an electrolyte, and a membrane (30) separating the anode from the cathode. The carbon nanotube array includes a plurality of multi-walled carbon nanotubes (23). Preferably, an average diameter of an outermost wall of the multi-walled carbon nanotubes is in the range from 10 to 100 nanometers, and a pitch between adjacent multi-walled carbon nanotubes is in the range from 20 to 500 nanometers. In the carbon nanotube array, the lithium ions are able to intercalate not only inside the multi-walled carbon nanotubes, but also in the interstices between adjacent multi-walled carbon nanotubes. Thus a density of intercalation of the carbon nanotube array is significantly higher than that of graphite.

A projecting device includes a light source, a filtering component, a reflecting mirror, a digital micro-mirror device, a projecting lens, and a panel. The filtering component changes lights emitted from the light source into substantially parallel polarized ultraviolet lights. The reflecting mirror reflects the substantially parallel polarized ultraviolet lights to the digital micro-mirror device. The digital micro-mirror device includes microscopic mirrors arranged in a rectangular array configured to be adjustable to reflect the substantially parallel polarized ultraviolet lights reflected by the reflecting mirror to the projecting lens. The projecting lens diverges the substantially parallel polarized ultraviolet lights. The panel includes a transparent substrate, a first fluorescence material layer, a second fluorescence material layer, and a third fluorescence material layer. The first, second, and third fluorescence material layers are positioned on the transparent substrate and emit red, blue and green lights when excited.

A lens module is also provided in the present invention.
Abstract:
An optical data storage system includes a light emitting and receiving device (30), a light transmission device (31) having an input port (32) and an output port (33). The input port is disposed adjacent to the light emitting and receiving device. Furthermore, a micro window is provided at the output port, and a diameter of the micro window is in a range of 5 to 70 nanometers. Therefore, in the optical data storage system, the spot size of the light beams is close to the diameter of the micro window. Accordingly, the size of the beam spot is small enough to write information at a higher density with respect to an optical storage medium.
