  • Energy Efficient Stud

    Type: 
    Product
    Technology:

    Pratt & Whitney has developed a wood-foam composite framing stud that provides improved insulation over existing wood products. The end product is a 2”X6” stud that has wood sections removed and replaced with insulating foam resulting in a framing member that has the strength of a 2”X4” stud with an R-value close to that of fiberglass. This stud offers additional function in structural support for additional floors and roof nailing surfaces for plywood and sheetrock and provides wall stiffness for wind exposure. Technology Applications: LEED Construction

  • Use of Acoustics to Disrupt and Deter Wood-infesting Insects from and within Trees

    Type: 
    Product
    Technology:

    Several exotic wood borers (Emerald Ash Borer and Asian Longhorn Beetle) potentially threaten the entire community of ash tree species and several other hardwood species (e.g. maples) in North America. The Mountain Pine Beetle a tree-killing bark beetle in western North America is currently impacting 8.4 million acres of conifer forests in Canada and northwestern US. Currently there are few options for insect control that are not chemically based. This new method provides a non-chemical means of insect prevention and control of tree-infesting pests that occur across all habitats.

  • Polyvinylpyrrolidone (PVP) for Enhancing the Activity and Stability of Platinum-Based Electrocatalysts

    Type: 
    Product
    Technology:

    Background: Direct-methanol fuel cells or (DMFCs) are a subcategory of proton-exchange fuel cells in which methanol is used as the fuel. DMFCs are useful for many portable power applications and micro power applications such as laptop computers cell phones etc. As a result DMFCs have been an area of intense research directed toward alternative sources of energy. As a fuel methanol (MeOH) is advantageous in terms of also being readily available from renewable sources of biomass such as wood.

  • Greatwoods: Genetically Optimized Black Walnut Trees

    Type: 
    Product
    Technology:

    Black walnut trees are one of the most valuable species in the United States. The hardwood is used in making quality lumber and veneer and has an added benefit of producing walnuts used in food production. Hardwood trees in general have many other benefits. They provide environmental stabilization as windbreakers protection from watershed and reclamation. The raw materials from the wood are used in cosmetic pharmaceutical and botanical industries.

  • Method for Producing Pulp

    Type: 
    Product
    Technology:

    Summary: The Wisconsin Alumni Research Foundation (WARF) is seeking commercial partners interested in developing an efficient method for producing pulp from wood chips. Detailed Technology Description: To make paper from wood wood must first be transformed into pulp. Current pulping techniques require high amounts of electrical energy or large quantities of wood. UW-Madison researchers have developed a method for producing pulp from wood chips by pretreating the chips with oxalic acid and sodium bisulfite.

  • Trees for Woody Biomass Applications: Improved Aspen Clones

    Type: 
    Product
    Technology:

    Background: Improved aspen clones that produce increased biomass have been developed at Iowa State University. Technology Description: Fast growing trees such as aspen cottonwood and eucalyptus can be grown as so-called short rotation crops and have potential to be used as a source of woody biomass for the production of biofuels such as wood pellets and cellulosic ethanol. In the prime cottonwood growing region which includes eastern Louisiana eastern Arkansas western Mississippi and western Kentucky cottonwoods can grow 12-15 feet per year allowing them to be harvested biennially.

  • Improving Biomass Conversion Efficiency by Modifying Lignin so Plant Cell Walls Are More Digestible and Fermentable

    Type: 
    Product
    Objective:

    Lignocellulosic biomass is a very desirable feedstock for biofuel production. If the fermentation process for lignocellulose could be optimized conversion of this biomass could yield 25 to 50 billion gallons of ethanol or other biofuels per year. However lignocellulose which is composed of lignin cellulose and hemicelluloses is resistant to chemical or enzymatic hydrolysis. This resistance is a key limiting step in the conversion of biomass into fermentable sugars.

  • Medium-Density Fiberboard (MDF) with Improved Water Resistance

    Type: 
    Product
    Technology:

    Background: Lignocellulose is a component of wood. It is used in a variety of products including medium-density fiberboard (MDF) an engineered wood product formed by gluing lignocellulose fibers under heat pressure and a small amount of resin. Cellulose hemicellulose and lignin are the major polymers that make up lignocellulose and contribute to the material characteristics of MDF. The MDF manufacturing process begins with a pulping procedure that creates a suspension of fibers from wood.
