Graphene is promising as a transparent, flexible, and possibly cost-effective substrate for nanowire-based devices. We have investigated Au-seeded III-V nanowire growth with graphite as a model substrate. The highest yield of undoped vertical nanowires was found for InAs, but we also observed vertical nanowires for the InP, GaP, and GaAs materials. The yield of vertical nanowires for GaP and Ga...

Context. The Solar Orbiter spacecraft made its first close perihelion passes in 2022, reaching 0.32 au on 26 March and 0.29 12 October. Transient activity was relatively low, making it possible to perform measurements of the quiet-time suprathermal ion pool over multi-day periods. Aims. inner heliosphere is a source seed particles accelerated by coronal mass ejection-driven shocks. Determining ...

Abstract In this work, we present the synthesis and surface immobilization of Au nanostars, nanocubes nanorods for localized plasmon resonance (LSPR)-based refractometric sensing applications. nanostructures exhibiting LSPR peak positions in 500–900 nm spectral range were prepared by seed-mediated method. The refractive index (RI) sensitivity all these colloidal solution measured sample highest...

7 ABSTRACT: The recently emerged selective lateral epitaxy 8 of semiconductor planar nanowires (NWs) via the vapor− 9 liquid−solid (VLS) mechanism has redefined the long10 standing symbolic image of VLS NW growthvertical NWs 11 extending out of the substrate. The in-plane geometry and self12 aligned nature make these planar NWs completely compatible 13 with large scale manufacturing of NW-base...

we have investigated structure and electronic properties of au and si liner chains using the firstprinciplesplane wave pseudopotential method. the transport properties and conductance of these twoliner chains are studied using landauer approaches based on density functional theory (dft). weobtain density of states and band gap using kohn-sham and wannier functions as well as quantumconductivity...

The microRNA (miRNA)-mediated repression of protein synthesis in mammalian cells is a reversible process. Target mRNAs with regulatory AU-rich elements (AREs) in their 3'-untranslated regions (3'-UTR) can be relieved of miRNA repression under cellular stress in a process involving the embryonic lethal and altered vision family ARE-binding protein HuR. The HuR-mediated derepression occurred even...

This paper describes the consonant inventory of the endangered southern African language N|uu. Our novel approach to segment classification accounts for all 73 N|uu consonants with just four phonetic dimensions (place, manner, phonation, airstream) and does away with the phonetically empty category CLICK ACCOMPANIMENT. We provide ultrasound data showing that the posterior constrictions in click...

Escherichia coli is an indicator in the quality control of pharmaceutical and other samples. Reduced graphene oxide (rGO) as a kind of carbon compositions was immobilized on glassy carbon electrode (GCE). Chronoamperometric and reduction methods were used for Au NPs decoration and it completed with polyclonal E. coli antibody and 0.5 W/V% Bovine Serum Albumin solution. Morphology and structure ...
