Publication number: 20170152142Abstract: A value inheritance widget system includes a display device including a user interface, and a value impact engine coupled to the display device. The value impact engine is configured to display at least one widget on a user interface. The widget includes a value. The value comprises an inherited value. The value impact engine is further configured to display information of a scope of inheritance of the value before user interaction with the widget. The information of the scope of inheritance of the value includes a number of inheritance levels of the value and a number of objects impacted by a change to the value. The value impact engine is further configured to receive a user input changing the value of the widget and change the value of the widget and the objects in response to receiving the user input.Type: ApplicationFiled: April 4, 2014Publication date: June 1, 2017Inventors: Keun Su Kim, Christopher T Kingston, Benoit Simard

Patent number: 9643944Abstract: Compounds are attached to carbon nanotubes (CNT) by a process which comprises: subjecting surface treated CNTs which have been treated to induce negatively charged surface groups thereon, to nucleophilic substitution reaction with a compound carrying a functional group capable of reacting with the negatively charged groups on the CNT surface, whereby the compound chemically bonds to the CNT. The surface CNT treatment may be reduction. The compounds which are bonded to the CNT may be epoxy resins, bonded directly or through a spacer group. Bi-functional CNTs, grafted to both epoxy resins and other polymers such as polystyrene, are also made by this process.Type: GrantFiled: January 29, 2013Date of Patent: May 9, 2017Assignee: National Research Council of CanadaInventors: Benoit Simard, Jingwen Guan

Publication number: 20160200578Abstract: A two-step sc-SWCNT enrichment process involves a first step based on selective dispersion and extraction of semi-conducting SWCNT using conjugated polymer followed by a second step based on an adsorptive process in which the product of the first step is exposed to an inorganic absorptive medium to selectively bind predominantly metallic SWCNTs such that what remains dispersed in solution is further enriched in semiconducting SWCNTs. The process is easily scalable for large-diameter semi-conducting single-walled carbon nanotube (sc-SWCNT) enrichment with average diameters in a range, for example, of about 0.6 to 2.2 nm. The first step produces an enriched sc-SWCNT dispersion with a moderated sc-purity (98%) at a high yield, or a high purity (99% and up) at a low yield. The second step can not only enhance the purity of the polymer enriched sc-SWCNTs with a moderate purity, but also further promote the highly purified sample to an ultra-pure level.Type: ApplicationFiled: August 18, 2014Publication date: July 14, 2016Inventors: Jianfu Ding, Patrick Malenfant, Zhao Li, Jacques Lefebvre, Fuyong Cheng, Benoit Simard

Patent number: 9284398Abstract: Modified carbon nanotubes are provided having carbon nanotube core covalently bound through C—C bonds to a polymer shell surrounding the carbon nanotube core. The polymer shell is a polymer having functional groups pointing outwardly from the shell. The functional groups are compatible with or able to covalently connect to another polymer. Such modified carbon nanotubes are more readily dispersed in a homogeneous manner in another polymer and may be used as a reinforcing filler in a polymer matrix. The modified carbon nanotubes with a core-shell structure in which the core has a substantially unidirectional orientation within the shell are produced by reacting neutral carbon nanotubes with 4-vinylaniline through a diazonium reaction in presence of one or more types of multifunctional monomers carrying a vinyl moiety and one or more functional groups for compatibilization with or connection to another polymer.Type: GrantFiled: June 10, 2011Date of Patent: March 15, 2016Assignee: National Research Council of CanadaInventors: Jingwen Guan, Robin Fraser, Benoit Simard

Patent number: 8834827Abstract: An integrated method and apparatus to continuously produce purified Single Wall Carbon Nanotubes (SWNT) from a continuous supply of solid carbon powder fed to an induction plasma torch. The apparatus includes a reactor body disposed to maintain laminar flow of gases with the torch body and coupled to a quenching body where temperature and residence time is controlled. Conveniently, functionalization may take place in the quenching body. The torch is operated with an argon carrier gas, an argon stabilizing gas and a helium sheath gas. Solid carbon reactants are preferably mixed with at least two metal catalysts containing nickel and cobalt with additional metal oxides of yttrium and cerium being desirable.Type: GrantFiled: March 14, 2006Date of Patent: September 16, 2014Assignees: National Research Council of Canada, Universite de SherbrookeInventors: Benoit Simard, Christopher Thomas Kingston, Stephane Denommee, Gervais Soucy, German Cota Sanchez
