  • Investigation of Epoxy-based Wood Adhesives

    Creator:
    Mousavi, Seyyed Yahya
    Abstract:
    Wood-based composites such as plywood and particleboard are produced with a thermoset adhesive via a hot-press process. At present, UF is the most commonly used thermoset adhesive for production of decorative plywood. The emission of the carcinogenic formaldehyde from UF-bonded panels during the use of panels affects the indoor air...

  • Formaldehyde-free wood adhesives from soybean protein and lignin : development and characterization

    Creator:
    Liu, Yuan
    Abstract:
    Presently, the production of wood composites relies on the formaldehyde-based wood adhesives such as phenol-formaldehyde (PF) and urea-formaldehyde (UF). However, their dependence on exhaustible fossil fuels and the emission of carcinogenic formaldehyde prompt to develop an environmentally friendly adhesive from renewable natural resources. This work focuses on development and characterization...

  • Development and evaluation of novel coupling agents for kenaf-fiber-reinforced unsaturated polyester composites

    Creator:
    Ren, Xiaofeng
    Abstract:
    Natural fibers are gaining popularity as reinforcement materials for thermoset resins over the last two decades. Natural fibers are inexpensive, abundant, renewable and environmentally friendly. Kenaf fibers are one of the natural fibers that can potentially be used for reinforcing unsaturated polyester (UPE). As a polymer matrix, UPE enjoys a...

  • Improved interfacial adhesion in wood-plastic composites : Development of new compatibilizers

    Creator:
    Zhang, Cheng
    Abstract:
    In wood-plastic composites (WPCs) a compatibilizer is often used to improve the interfacial adhesion between the hydrophilic wood filler and the hydrophobic plastic matrix. At present, while the basic concepts of compatibilization are understood, the optimized chemical structures of an effective compatibilizer, including the ideal structures of the wood-binding domain...

  • New application of crystalline cellulose in rubber composites

    Creator:
    Bai, Wen
    Abstract:
    Rubber without reinforcement has limited applications. The strength of reinforced rubber composites can be ten times stronger than that of unreinforced rubbers. Therefore, rubber composites are widely used in various applications ranging from automobile tires to seals, valves, and gaskets because of their excellent mechanical elastic properties. Silica and carbon...

  • Investigation of new compatibilizer systems for wood-polyethylene composites

    Creator:
    Geng, Yu
    Abstract:
    Wood-plastic composites (WPCs) are one of the fastest-growing sectors of the wood composites industry. However, the strengths of WPCs are typically low because of the poor interfacial adhesion between hydrophilic wood and hydrophobic thermoplastics. A compatibilizer that can form bridges between wood and plastics is required to give WPCs desirable...

  • Investigation of Styrene-Free Unsaturated Polyester Resins for Fiber-Reinforced Composites

    Creator:
    Wu, Yili
    Abstract:
    Most of existing commercial unsaturated polyester (UPE) resins are typically composed of a UPE and a high amount of highly volatile, flammable, and toxic styrene. The emission of hazardous styrene in the handling of the UPE resins and the preparation and use of fiber-reinforced UPE composites poses severe hazards to...

  • Electrical Conductivity in Mixed-Species Biofilms for Enhancing Energy Generation in Anaerobic Microbial Systems

    Creator:
    Li, Cheng
    Abstract:
    Further enhancement of energy generation is desired for practical application of anaerobic microbial systems such as microbial fuel cells (MFC) and anaerobic digesters (AD). A possible approach is to enhance the ability of microbial communities to transfer electron extracellularly in the form of electrical current. Critical to perform direct extracellular...

  • Preparation and Properties of Porous Carbon Materials

    Creator:
    Xing, Zhenyu
    Abstract:
    Porous carbon is indispensable in modern technology applications. It is used for energy storage, gas separation, water purification, catalyst support, and chromatography. The diversity of its applications stems from its unique properties, including high specific surface area, tunable pore volume, and chemical stability. Specifically, the large surface area provides high...

    Jin, Hyung Dae
    Abstract:
    Recent advances in nanocrystalline materials production are expected to impact the development of next generation low-cost and/or high efficiency solar cells. For example, semiconductor nanocrystal inks are used to lower the fabrication cost of the absorber layers of the solar cells. In addition, some quantum confined nanocrystals display electron-hole pair...
