Functionalized microscale 3D devices and methods of making the same. The 3D microdevice can be realized with the combination of top-down (lithographic) and bottom-up (origami-inspired self-assembly) processes. The origami-inspired self-assembly approach combined with a top-down process can realize 3D microscale polyhedral structures with metal/semiconductor materials patterned on dielectric materials. In some embodiments, the functionalized 3D microdevices include resonator-based passive sensors, i.e. split ring resonators (SRRs), on 3D, transparent, free-standing, dielectric media (Al.sub.2O.sub.3).

A wireless communications system is provided. A computer system runs on at least one platform on which a plurality of different lottery games for different jurisdictions are supported. The system includes a wallet. At least one computer readable storage medium stores computer executable instructions that, when executed by the at least one network processor in the workflow server residing in the mobile communications network, implement components including: a workflow module comprising sets of workflow instructions for processing different types of lottery game packets from a plurality of different jurisdictions; and a deep packet inspection module for inspecting a received lottery game packet and providing information about the lottery game packet to the workflow module.

Provided is a substrate processing apparatus that removes a film by supplying a processing liquid to the peripheral edge of a substrate. An ejection unit ejects the processing liquid to the peripheral edge of the substrate held and rotated by a substrate holding unit. An ejection position setting unit sets the ejection position of the processing liquid of the ejection unit to correspond to the removal width of the film included in a recipe, and a property information acquisition unit acquires property information of the film to be removed. A correction amount acquisition unit acquires the correction amount for correcting the ejection position of the processing liquid based on the property information of the film, and an ejection position correction unit corrects the ejection position of the processing liquid by the ejection unit based on the correction amount acquired by the correction amount acquisition unit.

A method of forming a polycrystalline diamond comprises derivatizing a nanodiamond to form functional groups, and combining the derivatized nanodiamond with a microdiamond having an average particle size greater than that of the derivatized nanodiamond, and a metal solvent-catalyst. A polycrystalline diamond compact is prepared by adhering the polycrystalline diamond to a support, and an article such as a cutting tool may be prepared from the polycrystalline diamond compact.

This invention relates to a method of manufacturing an object with microchannels provides therethrough, and more particularly, but not exclusively, to a method of manufacturing a micro heat exchanger with microchannels provided therethrough. The method includes the steps of providing a metal base layer made from a first metal; forming a plurality of spaced apart ridges, made from a second metal, on the base layer; depositing more of the first metal onto the ridges in order to cover the ridges; and re moving the ridges using a chemical etching process so as to produce microchannels in a body made of the first metal.
