  • Polymers and membranes for separation of polar organic compounds from aqueous mixtures and methods of using
    Patent number: 10086339
    Abstract: A polymer having a contact angle with water that is greater than or equal to 90° and a contact angle with 1,3-propane diol that is less than 90°. A pervaporation membrane comprising the polymer and a process for purifying a fermentation broth using a pervaporation membrane comprising the polymer is also described.
    Type: Grant
    Filed: March 10, 2016
    Date of Patent: October 2, 2018
    Assignee: THE UNIVERSITY OF CONNECTICUT
    Inventors: Richard Steven Parnas, Alexandru Asandei, Baishali Kanjilal, Iman Noshadi

  • Process for particleboard manufacture
    Patent number: 9381677
    Abstract: Improved particleboard and methods for fabricating improved particleboard (e.g., natural fiber/material-based particleboard) are disclosed. More particularly, the present disclosure provides systems/methods for fabricating particleboard (e.g., formaldehyde-free particleboard) utilizing natural fibers/materials (e.g., lignocellulosic materials), wherein the particleboard has improved performance characteristics and/or mechanical properties. Methods for fabricating fiber-reinforced biocomposites (e.g., natural fiber-reinforced wheat gluten biocomposites) are disclosed. For example, systems/methods for fabricating particleboard from lignocellulosic materials (e.g., coconut materials), along with a binder material (e.g., wheat gluten), are provided. In general, the fiber or lignocellulosic material is treated with sodium hydroxide and/or a silane coupling agent as an adhesion promoter to enhance interfacial adhesion between the fiber and the binder.
