Active nano-CuPt3 electrocatalyst supported on graphene for enhancing reactions at the cathode in all-vanadium redox flow batteries
Abstract Graphene-supported monometallic (Pt) and bimetallic (CuPt3) cubic nanocatalysts have been investigated as new positive electrode materials for improving the VO2+/VO2+ redox process occurringExpand

Heterostructured p-CuO (nanoparticle)/n-SnO2 (nanowire) devices for selective H2S detection
Abstract Dihydrogen sulphide (H2S) is a dangerous pollutant released in fossil combustion processes. Here, p-CuO (particle)/n-SnO2 (nanowire) heterostructures were evaluated as selective H2S sensors,Expand

Self-assembled GaN nanowires on diamond.
We demonstrate the nucleation of self-assembled, epitaxial GaN nanowires (NWs) on (111) single-crystalline diamond without using a catalyst or buffer layer. The NWs show an excellent crystallineExpand

Polarity-driven polytypic branching in cu-based quaternary chalcogenide nanostructures.
An appropriate way of realizing property nanoengineering in complex quaternary chalcogenide nanocrystals is presented for Cu2CdxSnSey(CCTSe) polypods. The pivotal role of the polarity in determiningExpand

Polarity and growth directions in Sn-seeded GaSb nanowires.
We here investigate the growth mechanism of Sn-seeded GaSb nanowires and demonstrate how the seed particle and its dynamics at the growth interface of the nanowire determine the polarity, as well asExpand

Solution-growth and optoelectronic performance of ZnO : Cl/TiO2 and ZnO : Cl/ZnxTiOy/TiO2 core–shell nanowires with tunable shell thickness
Arrays of vertically aligned ZnO : Cl/TiO2 and ZnO : Cl/ZnxTiOy/TiO2 core–shell nanowires (NWs) were prepared by means of the combination of two solution-growth processes. First, single-crystal ZnOExpand

Anisotropic magnetoresistance of individual CoFeB and Ni nanotubes with values of up to 1.4% at room temperature
Magnetic nanotubes (NTs) are interesting for magnetic memory and magnonic applications. We report magnetotransport experiments on individual 10 to 20 μm long Ni and CoFeB NTs with outer diametersExpand

Kinetic Engineering of Wurtzite and Zinc-Blende AlSb Shells on InAs Nanowires.
Using AlSb as the model system, we demonstrate that kinetic limitations can lead to the preferential growth of wurtzite (WZ) AlSb shells rather than the thermodynamically stable zinc-blende (ZB) AlSbExpand
