Asymmetric supercapacitors fabricated with ferrite/CHTL-derived hydrochar electrodes

Huynh K., Maddipudi B., Amar V.S., Shende A., Shende R., Shende A., Shende R., South Dakota School of Mines and Technology, US

Scientific community is striving for novel energy storage devices with superior power/energy density. Among these devices, asymmetric supercapacitors (ASCs) typically have higher power density as compared to batteries whereas higher energy density as compared to [...]

HTL Derived Biochar for Supercapacitor Electrodes

Huynh K., Maddipudi B.K., Amar V.S., Houck J.D., Shende R.V., South Dakota School of Mines and Technology, US

In this study, biochar samples were prepared by conversion of biomass feedstock (corn stover) via catalytic hydrothermal liquefaction (HTL) and later used as electrode material in conjunction with sol-gel derived perovskite based mixed (Mn,Ti)-oxides (Mn:Ti [...]

Conversion of carbon dioxide to methanol

Rahman G., Chung Y.H., Hallym University, KR

Carbon dioxide has been converted to methanol by means of electrochemical reduction using electrodes of metal oxides. The electrodes used in the conversion of CO2 consisted of Ru/Ir/Co oxides in the atomic ratios of Ru/Ir/Co [...]

Detecting oxidation and reduction of Cytochrome c on Single Nanoparticles in Flow Using SERRS

Choi Y., Edel J.B., Albrecht T., Imperial College London, UK

Surface enhanced Raman spectroscopy (SERS) is a powerful tool used for observing molecules and their structural properties, due to their ability to enhance the otherwise weak Raman scattering signals on a roughened metal surface or [...]

Structural and magnetic Properties of electrochemically grown Co-Fe and Ni-Fe alloy nanowire arrays

Pandya D.K., Kaur D., Chaudhary S., Kashyap S.C., IIT Delhi, IN

Magnetic nanowires are of immense importance in ultrahigh density magnetic storage media, micromagnetic sensors in read heads and spintronics devices. The nanowires of binary alloys of ferromagnetic metals like Co, Ni and Fe are particularly [...]

Interaction of Polyamido-amine (PAMAM) nanoparticles with the glassy carbon supported bilayer lipid membrane

Jadhav S.R., Mark Worden R., Michigan State University, US

Polyamido-amine (PAMAM) dendrimers are hyperbranched polymers with uniform particle size making them ideal monodisperse nanoparticles. PAMAM dendrimers are being pursued as non-viral vectors for gene delivery due to their low immunogenicity and their ability to [...]
