    High thermopower for liquid thermoelectrics

     

    Nano Energy, 31, 160-167, 2017

     

    Thermogalvanic cell (thermocell) represents a promising technology for converting low grade waste heat to electricity. For the cell to be attractive, however, the voltage generated for a given temperature difference has to be high. We report that the electrochemical thermopower can be more than doubled to 2.9 mV/K when an organic solvent with an appropriate solubility parameter is added to the aqueous electrolyte of ferri/ferrocyanide....read more

       

    Suctioning and Storing Liquid Body of Spilled Oil

     

    Scientific Reports, 6, 22339, 2016

     

    Despite remarkable strides in science and technology, the strategy for spilled oil collection has remained almost the same since the 1969 Santa Barbara oil spill. The graphene vessel devised here can bring about an important yet basic change in the strategy for spilled oil collection. When it is placed on the oil-covered seawater, the graphene vessel selectively separates the oil, then collects and stores the collected oil in the vessel...read more

     

    High Efficiency Thermal Energy Harvester

     

    Nature Communications, 7, 10600, 2016

     

    Conversion of low-grade waste heat into electricity is an important energy harvesting strategy. However, abundant heat from these low-grade thermal streams cannot be harvested readily because of the absence of efficient, inexpensive devices that can convert the waste heat into electricity...read more

     

     

    Nanotube Sheet Flutter for Harvesting Ambient Kinetic Energy of Moving Air

     

    Scientific Reports, 4, 6105, 2014

     

    Carbon nanotube aerogel sheets can exploit EMI to provide mechanical actuation at very low applied voltages, to harvest mechanical energy from small air pressure fluctuations, and to detect infrasound at inaudible frequencies below 20 Hz...read more

     

    Utilization of Body Heat for Powering Electronic Devices

     

    Nano Research, 7(4), 443-452, 2014

     

    Plastic thermo-electrochemical cells have been investigated as an alternative to conventional thermoelectrics for thermal energy harvesting. Plastic thermocells are flexible enough to be wearable on the human body and to be wrapped around cylindrical shapes...read more

     

    Fundamentals: Waste Thermal Energy Harvester

     

    Advanced Functional Materials, 22, 477-489, 2012

     

    Nanocarbon-based thermocells are investigated as an alternative to conventional thermoelectrics for thermal energy harvesting. The dependencies of power output on thermocell parameters are examined to provide practical design elements and principles...read more

     

    NanoMechanical Transducer

     

    Advanced Materials, 20 (16) 3131-3137, 2008

     

    We present an integrated approach for multilayered nanocomposite membrane made from layer-by-layer assembled polymers and single-wall carbon nanotubes. The integrated approach with bottom-up and top-down provides multifunctional molecular assemblies of tailored architectures and material properties...read more

     

    Sandwich-type Laminated Nanocomposites

     

    Advanced Materials, 19 (3), 427-432, 2007

     

    Here we report a novel layering approach for CNT/Cu laminated nanocomposites based on selective dip-coating of CNTs. Homogeoneous distribution of CNTs within the in-plane direction can be easily obtained by using a dip-coating of CNTs with a stable dispersive colloidal ...read more
