How can one obtain a stable and uniform anatase titanium dioxide coating of 100 nm over quartz by sputtering ?

Usually Ti metal target is used in oxygen atmosphere for thin oxide film formation during sputtering. What is the precise condition to be met while doing sputtering so that only anatase will be...

Can anybody suggest any way for introducing micron level roughness on a stainless steel plate ?

I want to build up roughness of the order of 0.1 micron to 1 micron on the surface of stainless steel. Upto 10 micron roughness it is ok.

If a water drop of 1 mm size hits a dry flat plate at 1 m/s, how much energy used for surface creation and how much will be viscos dissipation ?

Initially the drop has kinetic energy and surface energy. This combination has to be converted to excess new surface energy as the drop is stretched while hitting the plate and some energy will be...

Can any one suggest any way other than spin coating to coat a thin layer of titanium Oxide( 10-100 micron) on a substrate made of ss-316L ?

A film of around 10-100 micron is to be coated on the substrate, which is incompatible with a spin coater . Intention is to render the surface hydro-philic.
