DNAzyme based electrochemical sensors for trace uranium
We have developed a uranyl-specific DNAzyme that was immobilized on the surface of a gold electrode to give a highly sensitive and selective biosensor for uranyl ion. The typical DNAzyme system consisted of th...

Effect of SWCNT Dilution on the Resistivity of MgB2
We report an increase in superconducting temperature of magnesium diboride (MgB2) by minute single-wall carbon nanotubes (SWCNT) inclusions. The SWCNTs concentration was varied from 0.1wt% to 1.0wt%. The temperat...

Enhanced Performance of Symmetric Double Layer Capacitor by Flexible Binder-free SWCNT Membrane Electrodes
We present results on an aqueous symmetric double layer electrochemical capacitor (EDLC) constructed with a flexible binder-free single wall carbon (SWCNTs) membrane as electrodes. The capacitors were cycled f...

Nonionic Electrophoretic Sorting of SWCNTs into Metallic and Semiconducting Tubes
We present our preliminary results on a novel technique to electrophoretically sort singlewall carbon nanotubes into metallic and semiconducting tubes using a free-solution nonionic surfactant in a homemade el...

Polarized Induced Magnetic Broadening of Photonic Activities in Fe3O4-Elastomer Composites
We report a systematic study of polarization and magnetic field effects on the optical response of Fe3O4-silicone elastomer composite. The Fe3O4 particles were aligned in a silicone elastomer matrix with an exter...

Temperature Dependent Thermopower and Resistance Measurements of CNT-MgB2 Composites
The temperature dependent resistance R(T) and thermopower S(T) of sintered single wall carbon nanotubes (SWCNT) and magnesium diboride (MgB2) composites containing 5wt%, 10wt%, and 15wt% of SWCNTs have been measu...
