ELASTIC BEHAVIOUR OF PARTICULATE NITRIDE-NITRIDE OR BORIDE-NITRIDE COMPOSITES
1999High density refractory AlN-TiN, AlN-TiB2 and TiN-TiB2 composites, as well as the monolithic ceramics : i.e. aluminium nitride AlN, titanium nitride TiN and titanium diboride TiB2 were elabored by Hot Isostatic Pressing.Measurements of the Young's and Shear moduli of these polycrystalline materials were performed at room temperature by an ultrasonic ...

A highly regular mesh of hexagonal boron nitride with a 3-nanometer periodicity and a 2-nanometer hole size was formed by self-assembly on a Rh(111) single crystalline surface. Two layers of mesh cover the surface uniformly after high-temperature exposure of the clean rhodium surface to borazine (HBNH) 3 .

III-Nitride High Voltage Nitride Electronics
ECS Transactions, 2013The recent development of low dislocation density Aluminum Nitride (AlN) substrates allows the realization of a new class of majority carrier power devices. Majority carrier devices based on AlxGa1-xN grown on AlN substrates will be able to operate with breakdown voltages in excess of 20KV. A significant challenge to the development of these devices is

We report the synthesis, structure, and properties of novel bulk rhenium nitrides, hexagonal Re2N, and Re3N. Both phases have very high bulk moduli of >400 GPa, similar to the most incompressible binary transition-metal (TM) carbides and nitrides found to date. However, in contrast to other incompressible TM carbides and nitrides, Re3N is better placed

The successful synthesis of pure boron nitride (BN) nanotubes is reported here. Multi-walled tubes with inner diameters on the order of 1 to 3 nanometers and with lengths up to 200 nanometers were produced in a carbon-free plasma discharge between a BN-packed tungsten rod and a cooled copper electrode.

Titanium nitride-molybdenum metallizing method for aluminium nitride
Proceedings. Japan IEMT Symposium, Sixth IEEE/CHMT International Electronic Manufacturing Technology Symposium, 1990A paste containing molybdenum (Mo) and titanium nitride (TiN) powders was printed on aluminium nitride (AlN) substrates and fired. The adhesive strength of substrates metallized with Ni/Au plate was about 25 kg/2.5 mm/sup 2/ and was unchanged after a thermal cycle test.

Abnormal Nitride Morphologies upon Nitriding Iron-Based Substrates
JOM, 2013Nitriding of iron-based components is a very well-known surface engineering method for bringing about great improvement of the mechanical and chemical properties. An overview is presented of the strikingly different nitride morphologies developing upon nitriding iron-based alloy substrates.

The composition and microstructure of dispersed‐phase ceramic composites containing BN and AIN as well as BN and AIN single‐phase ceramics prepared by chemical vapor deposition have been characterized using X‐ray diffraction, scanning electron microscopy, electron microprobe, and transmission electron microscopy techniques.

Catalysis Propene is one of the highest-volume organic chemicals produced. Propene has mainly been made from naphtha, but changes in the global supply chain are creating shortages. Direct conversion from propane, a component of natural gas, via reaction with oxygen is an attractive alternative, but existing approaches produce a large fraction of ...
