Formation of Molybdenum Oxide Nano-whiskers during Heating Compressed Powder
In this study the synthesis of molybdenum oxide nano-whiskers with circular cross-section is performed. In some areas, it was observed that also some whiskers have open tips exhibiting their hollow structures. These whiskers have side dimensions ranging 2-5 μm with an average diameter in the nanometer rang. The structure suggested the vapor-liquid-solid growth mechanism (VLS). Scanning elect...
متن کاملEffects of Ferrosilicon Addition and Formation of Insitu SiC Nano-whiskers on MgO-C Refractories
Nowadays, SiC is one of the refractory materials which is used widespread because of its unique properties like structural stability in high temperatures. SiC nano whiskers are important in reinforcement of different kinds of composites like ceramic base materials, thanks to their outstanding mechanical, thermal, and chemical properties like low expansion coefficient, high thermal resistant, hi...

متن کاملThe Deformation of Nano-whiskers of Mono-crystalline Copper: Shape Effect, Properties, Shear Banding and Necking
This paper discusses some theoretical aspects in deforming nano-whiskers of monocrystalline copper by uniaxial tension. With the aid of the molecular dynamics analysis, the present study revealed that the behaviour of a nano-whisker is very sensitive to its size, crystal orientation and geometry. The most stable surface is with (111) atomic structure and the most reliable whisker for testing is...
