Publication number: 20160002457Abstract: Composite hydrogels with a chiral organization with tunable responsive photonic properties are conceived. A polymerizable hydrophilic monomer such as acrylamide is reacted in the presence of nanocrystalline cellulose (NCC) to give a composite hydrogel with cellulose nanocrystals embedded in a chiral nematic organization. Through control of the reaction conditions, the hydrogel can exhibit photonic colour that can be varied throughout the visible and near-infrared regions. The colour shifts substantially and reversibly upon swelling and shrinking of the hydrogel through solvation in aqueous and nonaqueous media. The responsive properties can be tailored both through choice of monomer and/or through chemical modification of the NCC surface. Examples of possible applications of the materials are: tunable reflective filters, chemical sensors, stationary phases for electrophoresis of chiral or achiral substances, and as a template to generate new materials with chiral nematic structures.Type: ApplicationFiled: February 12, 2014Publication date: January 7, 2016Applicants: Celluforce Inc., University of British ColumbiaInventors: Wadood Yasser HAMAD, Mark John MACLACHLAN, Joel Alexander KELLY, Kevin Eric SHOPSOWITZ

Patent number: 9129783Abstract: A method of mass spectrometry is disclosed comprising providing a mixture of different analyte ions and supplying electrons or reagent ions to said mixture so as to transfer charge to the analyte ions. The transfer of charge causes at least some of the analyte ions to dissociate and others of the analyte ions not to dissociate, but to form intermediate ions of altered charge state. These intermediate ions are then isolated from other ions and excited so as to dissociate into daughter ions. The intermediate ions and their daughter ions are analyzed and associated with each other so that the intermediate can be identified from their daughter ions. The analyte ions can then be identified from the intermediate ions, since they differ only in charge state. The disclosed method enables analyte ions to be associated with their fragment ions, and therefore identified, without having to isolate individual analyte ions prior to their interactions with the electrons or reagent ions.Type: GrantFiled: April 5, 2013Date of Patent: September 8, 2015Assignees: Micromass UK Limited, The University of British ColumbiaInventors: Jeffery Mark Brown, Damon Robb
