  • Solar water disinfection

    Type: 
    Technology
    Sectors:
    Objective:

    It is well documented that solar energy can be an effective means of cleaning contaminated water. This is because ultraviolet (UV) light destroys the formation of DNA linkages in microorganisms, thereby preventing them from reproducing and thus rendering them harmless.

  • Taking action: Progress and challenges in implementing nutrition policies and programs

    Type: 
    Publication
    Publication date:

    TO BE EFFECTIVE, COMMITMENTS TO ACTION MUST BE IMPLEMENTED AND ENFORCED. THE IMPLEMENTATION OF POLICIES AND INTERVENTIONS DEPENDS on converting political commitment to practical action. How are governments and other stakeholders doing in implementing policies and interventions that reflect commitment?

  • Making SMARTer commitments to nutrition action: Global nutrition report guidance note

    Type: 
    Publication
    Publication date:

    The Global Nutrition Report, an independent accountability mechanism for progress and action on nutrition, calls on all actors to make SMART Commitments to Nutrition Action—that is, commitments that are specific, measurable, achievable, relevant, and time bound. Specifically, we call on governments to make SMART Commitments to Nutrition Action to achieve national nutrition targets and to put in place monitoring systems that allow them and others to assess progress.

  • Global Nutrition Report 2016: From Promise to Impact: Ending Malnutrition by 2030: Summary

    Type: 
    Publication
    Publication date:

    Few challenges facing the global community today match the scale of malnutrition, a condition that directly affects one in three people. Malnutrition manifests itself in many different ways: as poor child growth and development; as individuals who are skin and bone or prone to infection; as those who are carrying too much weight or who are at risk of chronic diseases because of excess intake of sugar, salt, or fat; or those who are deficient in important vitamins or minerals.

  • Producing Olefins for Use in Gasoline Jet and Diesel Fuels from Chemicals Obtained from Levulinic Acid

    Type: 
    Product
    Technology:

    Levulinic acid is a biomass-derived compound that can be obtained inexpensively in high yields from waste cellulose-containing materials. It has been identified as a top biomass-derived chemical due to its ease of production for both five and six carbon sugars and its useful functional groups a ketone and a carboxylic acid. Levulinic acid can be used to form other more valuable chemicals including gamma-valerolactone (GVL). GVL is valuable as a renewable platform molecule with potential in developing both renewable energy and chemicals.

  • A Novel Process for Production of Biobutanol

    Type: 
    Product
    Technology:

    Recently there is a renewed interest on butanol production by using anaerobic Clostridia which can produce acetone butanol and ethanol with a ratio of 3:6:1 during the so-called ABE fermentation. However they are still many remaining challenges to use Clostridia for producing butanol. These challenges include acid crash due to excess acid production in the exponential growth phase degeneration of solvent producing capability due to repeated sub-culturing sporulation during solvent production and solvent intolerance.

  • Reduction Method of Excess Sludge

    Type: 
    Product
    Technology:

    In-situ transestrification is a method by which cell membranes disintegrate by disrupting the phospholipid bilayer structure of biomembrane. The reaction transforms fatty acids found in wastes to methyl esters a valuable feed used in the production of high-value biodiesel fuels. Additionally the extraction of fatty acids in cell membranes results in the solubilization of cell contents due to disintegration of the membrane. Recycling this solubilized sludge back to an aeration tank will reduce the net sludge production.

  • Method for Improving Cuphea Oil Seed Production by Eliminating Premature Pod Shattering

    Type: 
    Product

    Cuphea is a tropically grown flowering plant which is known as a rich source of medium-chain fatty acids having high commercial value. However this plant is not commercially utilized in large-scale agriculture due to its characteristic sequential maturation and release of oil seeds from the seed pods which precludes mechanized harvesting. Cuphea is generally harvested by hand at present.

  • Stretched Recast Nafion for PEM Fuel Cells

    Type: 
    Product

    Methods of treating Nafion (TM) proton exchange membrane (PEM) to improve resistance to permeability of methanol in DMFC (Direct Methanol Fuel Cell) operation. The PEM includes a semi-permeable polyelectrolyte film made of a recast polyelectrolyte acid polymer. The polyelectrolyte film extends along an axis and is uniaxially stretched along the axis. The polyelectrolyte film remains stretched when immersed in a methanol or methanol and water solution. Applications: PEM Fuel cells
