    Abstract: Systems and methods are provided for imaging using complex lasers. In general, a complex laser may be used as an electromagnetic source for an imaging application. The use of a lower spatial coherence configured complex laser in imaging applications may advantageously mitigate coherent artifacts in imaging such as cross-talk and speckle and improve overall image quality. Imaging applications where a complex laser may be useful include both incoherent imaging applications, such as digital light projectors and traditional microscopy, and coherent imaging applications, such as optical coherence tomography (OCT) and holography. The systems and methods provided also enable controlling the degree of spatial coherence of a complex laser.

  • Patent number: 9944829
    Abstract: Silicon carbide (SiC) etchants with a generic formula of MXO2, where M is an alkali metal, X is a halogen, O is oxygen are disclosed. When mixed with an abrasive powder in an aqueous slurry form, this MXO2 etchant acts as tribochemical reactant in enhancing the SiC material removal rate during chemical mechanical polishing (CMP). The material removal rates can sometimes go up to a few order of magnitudes, as compared to the slurry without this MXO2 etchant. Typical metal in the formula MXO2 are K (potassium) and Na (sodium), X includes Cl (chlorine), Br (bromine) and I (iodine). The whole series of MXO2 compounds belong to the chemical family of metal halites or ammonium halites. Sodium chlorite, NaClO2, the simplest and most available member of the halite family, is a typical example. The enhanced polishing rate can be utilized to significantly increase the throughput of CMP operation for non-oxide wafer polishing.

    Abstract: The invention concerns a method of treating an alkaline granular carbonatable material which contains aluminium metal and which has in particular a pH of at least 10. The method comprises an oxidation step wherein at least a portion of said aluminium metal is oxidized by contact with moisture. The aluminium should be oxidized to avoid swelling problems when using the granular material as aggregate.

The method further comprises a carbonation step wherein the granular carbonatable material is at least partially carbonated to lower the pH thereof. In this way the formation of ettringite, which may also release aluminium ions which causing further swelling problems, can be avoided in the granular material or any ettringite present therein can be destabilized.

  • Patent number: 8268269
    Abstract: As population density increases, the transportation of hazardous chemicals, including acids and disinfectants, lead to an increased incidence of spills while the consequences of spills become more serious. While solutions of halide acids, hypohalites and halites are safer disinfectants for transportation, handling, storage and use than traditional gaseous chlorine, the manufacturing cost of these disinfectants has here-to-fore limited their use. Economical processes are presented for the manufacture of O2, halogen oxides, halide acids, hypohalites, and halates; as well as polynucleate metal compounds, metal hydroxides and calcium sulfate hydrate (gypsum). The instant invention presents methods and processes that incorporate the use of sulfur. This is while environmental regulators, such as the US EPA, require an increased removal of sulfur from hydrocarbon fuels, thereby creating an abundance of sulfur, such that the refining industry is in need of a way to dispose of said abundance of sulfur.

  • Publication number: 20120195814
    Abstract: The invention concerns a method of treating an alkaline granular carbonatable material which contains aluminium metal and which has in particular a pH of at least 10. The method comprises an oxidation step wherein at least a portion of said aluminium metal is oxidised by contact with moisture. The aluminium should be oxidised to avoid swelling problems when using the granular material as aggregate. In the method according to the invention this oxidation is accelerated by providing at least one oxidising agent in said moisture, which oxidising agent has a higher redox potential than the water contained in said moisture. The method further comprises a carbonation step wherein the granular carbonatable material is at least partially carbonated to lower the pH thereof. In this way the formation of ettringite, which may also release aluminium ions which causing further swelling problems, can be avoided in the granular material or any ettringite present therein can be destabilised.

  • Patent number: 8231848
    Abstract: Ternary and quaternary Chalcopyrite CuInxGa1-xSySe2-y (CIGS, where 0?x and y?1) nanoparticles were synthesized from molecular single source precursors (SSPs) by a one-pot reaction in a high boiling solvent using salt(s) (i.e. NaCl as by-product) as heat transfer agent via conventional convective heating method. The nanoparticles sizes were 1.8 nm to 5.2 nm as reaction temperatures were varied from 150° C. to 190° C. with very high-yield. Tunable nanoparticle size is achieved through manipulation of reaction temperature, reaction time, and precursor concentrations. In addition, the method developed in this study was scalable to achieve ultra-large quantities production of tetragonal and quaternary Chalcopyrite CIGS nanoparticles.

  • Publication number: 20120128556
    Abstract: The oxine ligands 5-chloro-8-hydroxyquiniline and 5-sulfoxyl-8-hydroxyquinoline are covalently bound, using, for example, the Mannich reaction, to a silica gel polyamine composite made from a silanized amorphous silica xerogel and polyallylamine. The resulting modified composites, termed CB-1 (X?Cl) and SB-1 (X?SO3H), respectively, show a clear selectivity for trivalent over divalent ions and selectivity for gallium over aluminum. The compounds of the invention can be applied for the sequestration of metals, such as heavy metals, from contaminated mine tailing leachates.
