A nanowire of a semiconductor material and having a uniform cross-sectional area along its length is grown using a chemical vapor deposition process. In the method, a substrate is provided, a catalyst nanoparticle is deposited on the substrate, a gaseous precursor mixture comprising a constituent element of the semiconductor material is passed over the substrate, and adatoms of the constituent element are removed from a lateral surface of the nanowire during the passing of the precursor mixture. Removing the adatoms of the constituent element before such adatoms are incorporated into the nanowire prevents such adatoms from accumulating on the lateral surface of the nanowire and allows the nanowire to grow with a uniform cross-sectional area along its length.

A cooling device for cooling an electronic component. The device has an enclosure adapted to contain a liquid coolant. The enclosure has an internal channel system comprising a cavity adjacent the electronic component, a first group of arborizing channels adapted to carry the liquid coolant away from the cavity, a second group of arborizing channels adapted to carry the liquid coolant to the cavity, and a plenum fluidically connecting the first and seconds groups of arborizing channels. Each group of arborizing channels has a parent branch and multiple successive sets of daughter branches with successively smaller cross-sectional areas, wherein the sum of the cross-sectional areas of the daughter branches of any set is approximately the same as that of its parent branch. Distal sets of the daughter branches are most distant from the cavity, fluidically connected to the plenum, and have the smallest cross-sectional areas of the daughter branches.

UV-glossing for simplex and duplex prints, wherein an input member having thereon a pre-gloss toner image including UV-curable toner is moved, in non-slip association with a smooth UV-transparent web, jointly with the web through a plurality of process zones sequentially including a heating zone and an exposure zone, thereby producing an output member having a glossed, UV-cured, surface. In the heating zone, at least the outermost toner of the pre-gloss toner image is heated to a molten state in contact with the web. In the exposure zone, with the molten state being maintained, at least the outermost toner which contacts the web is cured by a flux of UV radiation transmitted through the web. In a preferred embodiment, the UV-curable toner is formed as an outer layer on the pre-gloss toner image.
