Visible Room Temperature Photoluminescence in Wet-Chemically Etched Silicon Nanowires
Sivakov V.A., Voigt F., Brönstrup G., Bauer G., Christiansen S.H., Institute of Photonic Technology, DE
Strong room temperature visible (red-orange) photoluminescence (PL) has been observed in wet chemically etched heavily (10E19 cm-3) and lowly (10E15 cm-3) doped silicon nanowires (SiNWs). Our observations strongly suggest that visible light emission at room [...]
Iron based 1D Nanostructures by Electrospinning Process
Eid C., Brioude A., Salles V., Plenet J.-C., Asmar R., Monteil Y., Khoury A., Khoury R., Khoury A., Khoury R., Miele P., Université Claude Bernard-Lyon 1, FR
Due to their strong shape anisotropy, one-dimensional (1D) nanomaterials, including nanotubes, nanowires and nanofibers exhibit specific properties that are not observed in the case of their bulk or particle counterparts.1 Moreover, when such nanomaterials display [...]
Nanopore detection of nerve agent degradation products
Guan X., Gupta J., Zhao Q., de Zoysa R.S., Jayawardhana D.A., The University of Texas at Arlington, US
Improved analytical capability for detection of organophosphate chemical agents (i.e. nerve gases) remains a high priority need in our continuing defense against future terrorist attacks. A nanopore stochastic sensing method for the rapid detection of [...]
The Potential of Silicon-Based Ligands in Metal-Organic Frameworks
The synthesis and characterisation of metal-organic frameworks (MOFs) based on metal centres linked by silicon-containing ligands and the investigation for their ability to take up small magnetically active molecules in order to look at the [...]
Characterization of Nanostructured Phenolic and Epoxy Composites Under Pulse Laser Degradation
Phenolic and epoxy nanocomposites were fabricated and exposed to pulsed laser. The nanoreinforcements were alumina nanofibers (ANF) and multi-walled carbon nanotubes (MWCNT). The loading of the nanoreinforcement was kept the same for both the epoxy [...]

Structural and magnetic Properties of electrochemically grown Co-Fe and Ni-Fe alloy nanowire arrays
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 [...]
Crystalline/amorphous silicon core/shell nanowires under external loads: An atomistic simulation study
The nanomechanical properties of Si/a-Si core-shell NWs are investigated using molecular dynamics simulations with EDIP model. Under uniaxial compressive and tensile loading, the computed Young’s modulus increases as the radius of crystalline core increases and [...]
