    Objective:
    Sectors:

    The UNFCCC Climate Technology Centre and Network (CTCN), the World Intellectual Property Organization’s Initiative (WIPO), the Northeast Water Innovation Network (NEWIN), and InvenTrust are inviting to join an innovation competition to address two key challenges, essential in pathways to a global, safe, and sustainable future:

    • Energy Efficient Water Desalination
    • Eliminating Leakage in Water Distribution

  • TTD Industrial waste treatment

    Type: 
    Product

    Tamar Technological Development r seals eliminate leakages in the main factories in Israel and were successfully installed in .USA Italy Brazil and Netherlands. The new MTZ shaft sealing technology has been introduced by Tamar Technologies This product is especially effective in sealing pumpage with particulates as well as for clear liquids It has application for pumps mixers agitators ribbon blenders and fans in addition to sealing shafts for dry powder handling. The Tamar Seal is analogous to a double mechanical seal that uses a flexible sealant as a barrier fluid.

  • Surface Treatment For Preventing Potential Induced Degradation of Photovoltaic Modules

    Type: 
    Product

    As solar cells continue to become more cost and energy efficient photovoltaic modules generate increasingly greater amounts of power at increasingly higher voltages. Potential induced degradation (PID) is the deterioration of a PV cell’s capability to generate power due to harmful leakage currents that neutralize its sunlight absorption regions. PID is worsened by high voltages high temperatures and humidity and power losses can take several months to a few years to become noticeable. PID can be prevented by disrupting the surface conductivity path of the leakage current.

  • TFB:TPDSi2 Interfacial Layer As A PEDOT:PSS Replacement in Organic Photovoltaic Cells

    Type: 
    Product

    Background: This technology obviates the need for the commonly employed PEDOT:PSS layer and significantly improves the performance of MDMO-PPV:PCBM bulk heterojunction (BHJ) solar cells. While organic photovoltaics (OPV) offer advantages over traditional inorganic photovoltaic cells including fabrication on lightweight flexible substrates and use of lower cost spin-coating and printing processes it lacks sufficient power conversion efficiency for commercial use.

  • High Performance Forward Osmosis Membrane from Cellulose Acetate and Cellulose Acetate Derivatives

    Type: 
    Product

    The invention disclosure relates to a technology of membrane formulation and fabrication to produce membranes with high water flux and high salt rejection for FO applications based on cellulose acetate (CA) and its derivatives. The FO membrane of the present invention is for single-layer hollow fiber membranes but it is also applicable for dual-layer hollow fiber membranes. This results in a novel membrane with high performance and high packing density.

  • High Precision Carbon Dioxide Detection for Geological Reservoirs

    Type: 
    Product
    Technology:

    Background: Large-scale sequestration of carbon dioxide in underground geological reservoirs is being actively explored as a means to sustain fossil energy use and minimize climate risks. Assuring the integrity of the huge carbon dioxide plume sequestered in such underground reservoirs is central to the viability and acceptability of this approach. It is known that carbon dioxide can leak from underground storage reservoirs. The U.S. Department of energy has set a limit on carbon dioxide leak rates of 0.01 percent per year to the atmosphere.

  • Low Swing Dual Threshold Voltage Domino Logic Circuits

    Type: 
    Product

    Background: Domino logic circuit techniques have been extensively applied in modern high-performance microprocessors because of their superior speed and area characteristics as compared to static complementary metal oxide semiconductor (CMOS) circuits. However the domino logic gates frequently consume more dynamic switching power and display weaker noise immunity than static CMOS gates. Current aggressive circuit design which focus solely on enhancing circuit speed in microprocessors consume power levels that impose a limiting factor on system performance and functionality.
