Patent number: 7507317Abstract: This invention relates to the enhancement of chemical reactions by applying a high frequency electric field to a material. The frequency and amplitude of the electric field are selected in accordance with the properties of the reacting components in the bulk of chemical reactor. In general, the high frequency range is determined by the dielectric properties of reactant(s), that is, at any given temperature, when, for example, the specific conductivity starts to grow from its low frequency value. Typically, frequencies in the range of 100 kHz to 200 MHz or greater are suitable for the enhancement of the reactions. An electric field of any shape having Fourier components that when applied to a chemical process exhibits growth in the real part of conductivity relative to the low frequency value is of particular importance.Type: GrantFiled: June 30, 2004Date of Patent: March 24, 2009Assignee: Alberta Research Council Inc.Inventors: Alexander Joseph Babchin, Jian-Yang Yuan, Ezra Eddy Isaacs, Haibo Huang, Ross Sam Chow, Richard Anthony McFarlane, Dmytro Vassily Prudkyy

Patent number: 7364640Abstract: A process for removing silica from nonwood plant materials involving both chemical and mechanical action is described. The silica-rich epidermal cells are liberated mechanically by a pre-pulping and low-consistency refining step and subsequently removed from the pulp via the filtrate of a thickening step. Amorphous silica is liberated chemically by using an alkaline dilution source in the pulper, then removed from the pulp via the filtrate of a thickening step and a dewatering step. The silica is then removed from the filtrate by adjusting the pH, followed by a separation step. The desilicated fibrous material may then be chemically or mechanically pulped and bleached using known processes. The silica removed from the nonwood plant material may then be used as a feedstock for other applications.Type: GrantFiled: September 7, 2004Date of Patent: April 29, 2008Assignee: Alberta Research Council Inc.Inventors: Wade Chute, Sofia Vichnevsky

Publication number: 20080092254Abstract: The present invention provides transgenic plants with reduced levels of saturated fatty acids in the seed oil and methods of making these plants. The transgenic plants developed through this method contain reduced levels of saturated fatty acids in seed oil due to expression of a prokaryotic delta-9 desaturase enzyme (i.e. an enzyme that introduces cis double bonds at the delta-9 position of saturated fatty acids) operably linked with an endoplasmic reticulum retention and retrieval signal sequence. One example of the invention is a plant expressing a heterologous delta-9 desaturase enzyme from cyanobacterium Anacystis nidulans, which converts lipid-bound 16:0 and 18:0 fatty acids into corresponding 16:1 and 18:1, in operative linkage with a KKSS (SEQ ID NO:5) endoplasmic reticulum retention and retrieval signal sequence.Type: ApplicationFiled: December 17, 2004Publication date: April 17, 2008Applicant: Alberta Research Council Inc.Inventors: Salehuzzaman Shah, Randall Weselake
