  • Publication number: 20190160023
    Abstract: The present invention relates to the use of cannabidivarin (CBDV) in the treatment of autism spectrum disorder (ASD) and ASD-associated disorders such as Fragile X syndrome (FXS); Rett syndrome (RS); or Angelman syndrome (AS). In a further embodiment the invention relates to the use of CBDV in the treatment of schizophrenia. CBDV has been shown to be particularly effective in improving cognitive dysfunction in rodent models of ASD, FXS, RS, AS and schizophrenia. The CBDV is preferably substantially pure. It may take the form of a highly purified extract of cannabis such that the CBDV is present at greater than 95% of the total extract (w/w) and the other components of the extract are characterised. Alternatively, the CBDV is synthetically produced.

  • Publication number: 20180195203
    Abstract: Electrochemical liquid phase epitaxy (ec-LPE) processes and devices are provided that can form precipitated epitaxial crystalline films or layers on a substrate. The precipitated films may comprise a semiconductor, such as germanium, silicon, or carbon. Dissolution into, saturation within, and precipitation of the semiconductor from a liquid metal electrode (e.g., Hg pool) near an interface region with a substrate yields a polycrystalline semiconductor material deposited as an epitaxial film. Reactor cells for use in an electrochemical liquid phase epitaxy (ec-LPE) device are also provided that include porous membranes to facilitate formation of the precipitated epitaxial crystalline films.

  • Patent number: 9388498
    Abstract: An electrochemical liquid-liquid-solid (LLS) process that produces unlimited amounts of crystalline semiconductor, such as Ge or Si, from aqueous or polar solutions with tunable nanostructured shapes without any physical or chemical templating agent is presented. Dissolution into, saturation within, and precipitation of the semiconductor from a liquid electrode (e.g., Hg pool) or near an electrode comprising metallic nanoparticles (e.g., In nanoparticles) yields a polycrystalline semiconductor material, as deposited. Such a process can be conducted at conditions, in a single step, and under electrochemical control, while affording control over formation of a variety of material morphologies. Materials formed by such processes are also provided.

  • Patent number: 9048188
    Abstract: This invention provides a semiconductor having a functionalized surface that is resistant to oxidation and that includes a plurality of atoms of a Group III element bonded to organic groups. The functionalized surface has less than or equal to about 1 atom of the Group III element bonded to an oxygen atom per every 1,000 atoms of the Group III element bonded to the organic groups, as determined using X-ray photoelectron spectroscopy. This invention also provides a method of functionalizing the surface and includes the step of halogenating at least one of the plurality of atoms of the Group III element to form halogenated Group III element atoms. The method also includes the step of reacting at least one of the halogenated Group III element atoms with a Grignard reagent to form a bond between the at least one Group III element atom and the organic groups.

  • Publication number: 20070275160
    Abstract: CNF electrodes disclosed herein may be conveniently prepared on conductive substrates by pyrolysis of iron(II) phthalocyanine in a reducing atmosphere. Such electrodes may possess suitable properties for preparation of electrocatalytic electrodes and electrochemical sensors. High surface area nitrogen doped CNFs prepared according to certain embodiments are conductive and may exhibit high stability and improved catalytic activity for O2 reduction in aqueous solutions.
