Semisolid Processing of Al/β-SiC Composites by Mechanical Stirring Casting and High Pressure Die Casting

Fabrication of Ti/SiCf metal matrix composites by vacuum plasma spraying

TiISiC, MMC monotapes have been successfully fabricated by vacuum plasma spraying. The as-sprayed MMC monotapes have a uniform fibre distribution, dense matrix and no fibre-matrix interfacial reaction. The effects of processing parameters such as H, flow rate, plasma current, chamber pressure and spray distance on the monotape temperature, porosity and fibre infiltration have been evaluated qua...

Fabrication of ZnO Nanowires Arrays by Anodization and High-Vacuum Die Casting Technique, and Their Piezoelectric Properties

In this investigation, anodic aluminum oxide (AAO) with arrayed and regularly arranged nanopores is used as a template in the high-vacuum die casting of molten zinc metal (Zn) into the nanopores. The proposed technique yields arrayed Zn nanowires with an aspect ratio of over 600. After annealing, arrayed zinc oxide (ZnO) nanowires are obtained. Varying the anodizing time yields AAO templates wi...

Controllable fabrication of oriented micro/nanowire arrays of dibenzo-tetrathiafulvalene by a multiple drop-casting method.

A multiple drop-casting method of growing the ultralong dibenzo-tetrathiafulvalene (DB-TTF) micro/nanowire arrays has been developed which has the success ratio as high as 94%. This method enables the arrays with a length over a few hundreds of micrometers to locate between droplets with the definite orientation. The width of the micro/nanowires is controlled via tuning the concentration of DB-...

Fabrication of Chitosan Silk-based Tracheal Scaffold Using Freeze-Casting Method

Background: Since the treatments of long tracheal lesions are associated with some limitations, tissue engineered trachea is considered as an alternative option. This study aimed at preparing a composite scaffold, based on natural and synthetic materials for tracheal tissue engineering. Methods: Nine chitosan silk-based scaffolds were fabricated using three freezing rates (0.5, 1, and 2°C/m...
