A hierarchical structure of one-dimensional CeO2/SnO2 core–shell nanowires on a three-dimensional porous disk (namely the “nanowire forest”) could maximize the reaction surface area and avoid coarsening during hydrogen generation.

In this short review, we report the facile fabrication of various interesting multi-component nanostructures including arrays of core-shell nanowires, multiwall nanotubes, segmented nanowires and multilayer stacked nanodisks, using anodized alumina membrane (AAM). We demonstrate that metallic (Cu, Ni and Au) and polymeric (PPV and PPy) one-dimensional (1D) arrays can be readily prepared by electrochemical deposition into the AAM. By optimizing the experimental design and conditions, we developed techniques to produce various multi-component nanostructures such as polymer/metal or metal/metal core-shell nanowires as well as nanotubes, with reasonably good control over both the length and the shell thickness of the nanostructures. Furthermore, we extend this method to make segmented nanowires as well as multilayer stacked nanodisks. Selective functionalization of the segmented nanowires resulted in end-on or side-on adhesion of nanowires during assembly. We illustrate the possibility of utilizing these 1D arrays to present patterns with luminescent and/or magnetic properties at this length scale.

Growth Method

As one-dimensional GaN material has excellent physical properties, it owns a huge prospect in the field of optoelectronic devices, and nanowire is currently one of the hotspots, at home and abroad, which had already invested a considerable force into the GaN nanowires. This paper studied the growth method based on Gas Liquid Solid (VLS) mechanism using Ni as catalyst in a chemical vapor deposition (CVD) system. By scanning electron microscopy (SEM), energy dispersive X-ray fluorescence (EDX) spectroscopy, transmission electron microscopy (TEM) test, we focused on the influence of temperature and pretreat on the morphology and properties of GaN nanowires. At the same time, we explored the law and gave an appropriate explanation.

Oedometer Tests

Creep is a common phenomenon for soft clays. The paper focuses on investigating the influence of temperature on the time-dependent stress-strain evolution. For this purpose, the temperature-dependent creep behavior for the soft clay has been investigated based on experimental observations. A thermally related equation is proposed to bridge the thermal creep coefficient with temperature. By incorporating the equation to a selected one-dimensional (1D) elastic viscoplastic (EVP) model, a thermal creep-based EVP model was developed which takes into account the influence of temperature on creep. Simulations of oedometer tests on reconstituted clay are made through coupled consolidation analysis. The bonding effect of the soil structure on compressive behavior for intact clay is studied. By incorporating the influence of the soil structure, the thermal creep EVP model is extended for intact clay. Experimental predictions for thermal creep oedometer tests are simulated at different temperatures and compared to that obtained from reconstituted clay. The results show that the influence of temperature on the creep behavior for intact clay is significant, and the model, this paper proposed, can successfully reproduce the thermal creep behavior of the soft clay under the 1D loading condition.

ABSTRACTIn this paper, we present our recent studies on the synthesis and magnetoresistance of single crystalline Fe3O4 core-shell nanowires and nanotubes. Homogeneous Fe3O4 nanowires/tubes with controllable length, diameter and wall thickness were synthesized. The as-prepared material composition and stoichoimetry have been carefully examined and confirmed with a variety of characterization techniques including XRD, EDS, XPS, and TEM. Magnetoresistance under different temperatures was systemically studied. Up to 1.2% room temperature magnetoresistance was observed in the as synthesized nanowires/tubes under a magnetic field of B = 1.8 T.
