In this work, the stability and electronic structure of zigzag double-walled silicon carbide nanotubes (DWSiCNTs) (6,0)@(n,0) (with n=11-17) were investigated by using ab initio Van der Waals density functional. By calculating the formation energy and the binding energy of each double walled nanotube, the best interwall distance for the outer nanotube was indicated. The results revealed that (1...
Silicon Carbide is often proposed as a sensor material for use in harsh environment applications such as monitoring gas turbines and internal combustion engines. However, little SiC survivability research has been reported for these environments. In this work, data is reported for silicon and amorphous silicon carbide (a-SiC) coated die survivability in a combustion engine with an exhaust tempe...
We have demonstrated the ability to perform a ductile material removal operation, via single-point diamond turning, on single-crystal silicon carbide (6H). To our knowledge, this is the first reported work on the ductile machining of single-crystal silicon carbide (SiC). SiC experiences a ductile-to-brittle transition similar to other nominally brittle materials such as silicon, germanium, and ...
"Advances in Silicon Carbide Processing and Applications" specifically targets the technology of two key application areas, propulsion systems in electronic vehicles and sensors for deployment in extreme environments. Edited by Steven Saddow & Anant Agarwal, two highly respected researchers in the field of SiC, with contributions from a range of eminent scientists, the book offers a real insigh...
Several methods of transformation are currently available for delivering exogenous DNA to plant cells. Agrobacterium-mediated transformation, microprojectile bombardment and direct protoplast transformation are routinely used today. However, each of them has certain disadvantages, which led to research into the development of novel alternative systems such as infiltration, electroporation of ce...
