Laser enhanced plating

Laser assisted Pd seeding for electroless plating on SiQ2

Plating Hydrogen

Cathodic activation examined with reference to the cold fuslon developments (controversy). Historically cathodic activation has been used for plating preparation of p a s s i v e (o x i d e) s u r f a c e s e.g. nickel/chromium alloys, niobium and powdered metals. More recent results of work employing cathodic activation for preparing aluminum for plating will be presented e.g. process paramete...

Multichannel plating unit for high-throughput plating of cell cultures.

High-throughput genomic approaches to gene function or target identification have led to the development and implementation of the 96-well format for many standard molecular biology manipulations. The apparatus described here, a Multichannel Plating Unit, is designed to plate out individual cultures efficientlyfrom standard 96-well culture blocks. Following transformation, aliquots of culture a...

Enhanced temperature uniformity by tetrahedral laser heating

Temperature profile on a spherical sample that is heated by laser beams in various geometries while processed in vacuum is analyzed. Sample heating by one or four laser beams was considered. An analytical expression was derived for directional sample heating cases. It suggests an enhanced temperature uniformity over the samples when heated with four diffuse laser beams arranged in a tetrahedral...

Polarization-enhanced absorption spectroscopy for laser stabilization.

We demonstrate a variation of pump-probe spectroscopy that is particularly useful for laser frequency stabilization. The polarization-enhanced absorption spectroscopy (POLEAS) signal provides a significant improvement in signal-to-noise ratio over saturated absorption spectroscopy (SAS) for the important and commonly used atomic cycling transitions. The improvements can directly increase the sh...
