Mechanochemical route to the synthesis of nanostructured Aluminium nitride

Hexagonal Aluminium nitride (h-AlN) is an important wide-bandgap semiconductor material which is conventionally fabricated by high temperature carbothermal reduction of alumina under toxic ammonia atmosphere. Here we report a simple, low cost and potentially scalable mechanochemical procedure for the green synthesis of nanostructured h-AlN from a powder mixture of Aluminium and melamine precurs...

The nitrogen vacancy in aluminium nitride

We have carried out a computational study for the nitrogen vacancy in charge states +3, +2 and +1 in AlN in the metastable zinc-blende phase. The vacancy and its four nearest-neighbour Al ions are treated as a molecular cluster, embedded in an infinite classical shell-model crystal. The following ground state properties, all of which are determinable from experiment, have been calculated: total...

Breakthrough Interventional Treatment Technology

The St. Antonius Hospital Utrecht/Nieuwegein, the Netherlands, and Philips have announced an important breakthrough in the image-guided treatment of vascular patients. Using an innovative X-ray technology developed by Philips, the hospital’s interventional radiologists were able to dramatically reduce the amount of Xray radiation that patients are exposed to during image-guided endovascular pro...

Thermal and electrical conductivity of Aluminium Nitride nanofluids

This study was designed to experimentally measure the thermal and electrical conductivities of Aluminium Nitride/Ethylene Glycol (AlN/EG) nanofluids. Transmission electron microscopy (TEM) was used to characterize the shape of AlN nanoparticles. Nanofluids with different particle volume concentrations of 0.5%, 1%, 2%, 3%, 4%, and 5% were utilized. The thermal and electrical conductivities of the...
