    Abstract: Improved crude oil processing is achieved by viscoelastic shearing of crude oil at an elevated temperature. The shearing provides for an enriched light fraction and an enriched heavy fraction that can be more efficiently separated by distillation. Shearing is achieved using a mobile surface and immobile surface, or other flow geometry, under conditions providing for a transient phase separation.

    Abstract: A Bradbury-Nielson gate (BNG) includes a set of evenly spaced, co-planar, and parallel wires. The wires alternate in a repeating ABAB pattern, where all of the A wires are electrically connected to each other, all of the B wires are electrically connected to each other, and the set of A wires is electrically isolated from the set of B wires. Improved fabrication of Bradbury-Nielson gates is provided based on two key ideas. The first key idea is the use of wire positioning template surfaces having wire insertion features with enhanced spacing. Wire insertion features having enhanced spacing allow for non-microscopic assembly of finely spaced wire arrays. The second key idea is the use of two template surfaces, each having wires spaced by twice the eventual gate wire spacing. The use of two template surfaces facilitates making the alternating electrical contact required for a BNG.

    Abstract: The present invention provides a method of coating an electrospray emitter with silver and then gold utilizing wet-coating processes. First, the electrospray emitter is immersed in a silver-containing liquid solution to coat the electrospray emitter in a layer of silver. Next, the silver-coated electrospray emitter is removed from the silver solution and rinsed with water. The silver-coated electrospray emitter is then annealed to stabilize the silver layer. Once the silver layer has been stabilized, the silver-coated electrospray emitter is immersed into a gold-containing liquid solution and a voltage is applied. This voltage serves to electrochemically deposit a gold layer onto the silver layer. The gold- and silver-coated electrospray emitter is then removed from the gold-containing liquid solution and rinsed with water and, preferably, with nitric acid.

    Abstract: A container to be positioned in a ring-down optical cavity for containing a sample includes an outer surface having opposing first and second outer faces and an inner surface forming a void for containing the sample and having opposing first and second inner faces. The container may include a first portion forming the first outer face having a second index of refraction and a second portion forming the second outer face having a third index of refraction. The container may be placed in an optical cavity including a medium. The first and second outer faces of the outer surface and the first and second inner faces of the inner surface are oriented so that the cavity-to-container interfaces and the container-to-sample interfaces of the container transmit and receive a light beam at an incidence angle approximately equal to the Brewster's angle of the respective interface.

The pulse-by-pulse cavity ring-down spectroscopy system enables for measuring absorption spectra of rapidly evolving systems on the order of the roundtrip time. The pulse-by-pulse analysis of ring-down profiles enables non-exponential ring-down absorption dynamics to be determined.

    Abstract: A mixture of chromatographic particles and a solution of water, alcohol and metal alkoxide may be injected by means of a syringe into a capillary column as a gel. The volatile components in the gel are evaporated by means of heating and gas pressure reduction to form a porous sol-gel glass matrix attached to the inner wall of the separation channel. The pores are large enough for the passage of protons, neutral and ionic species but are too small to permit significant leaching of the chromatographic particles. The separation column so formed requires no frits to maintain the glass matrix in place in the column. Electrical potential difference and/or pressure difference may be applied to cause fluid flow in the separation column to cause electrophoretic and chromatographic separation.
