Hydrothermal treatment of aluminum anodic coatings at high pressures.

Anodic aluminum oxide microchannel plates

A new material for microchannel plates (MCP) is proposed — anodic aluminum oxide. Microchannel plates made of this material may be much cheaper than with conventional lead glass MCP. Also a significantly smaller channel diameter (up to 70 nm) is easily achievable, which means better spatial resolution and the possibility to operate in strong magnetic fields. Methods and means are developed for ...

Surface modification of titanium with hydrothermal treatment at high pressure.

Surface modification of titanium was investigated by means of hydrothermal treatment with a maximum pressure of 6.3 MPa (280 degrees C temperature) in CaO solution or water to improve bioactivity and biocompatibility. As a result, calcium titanate was formed on the titanium surface. Moreover, titanium oxide and titanium hydroxide layers on the surface increased as temperature and pressure incre...

Plasma interferometry at high pressures

A general formulation for the measurement of plasma density and effective collision frequency for lowly as well as highly, collisional plasmas using millimeter wave interferometry is presented. In the presence of high density and collisionality at high gas pressures where the collision frequency ~n! is of the order of both the plasma (vp) and the wave frequency of the millimeter wave ~v! (n ;v ...
