A low-cost, solution-processed, versatile, microfluidic approach is developed for patterning structures of highly conductive metals (e.g., copper, silver, and nickel) on chemically modified flexible polyethylene terephthalate thin films by in situ polymer-assisted electroless metal deposition. This method has significantly lowered the consumption of catalyst as well as the metal plating solution.
one of the most important factors in study of project’s , is the study of environmental opportunities factors the permanent study of environmental opportunity factors . the study of permanent environmental changing and knowing golden threats’ cooperate with possible threats and at the result in structure forming and future skeleton of organization has a vital effects . the petrochemical industr...
A new membrane process is described that can be used to recoverplating chemicals from electroplating rinse waters. The process, called coupled transport, is based on liquid membranes that are comprised of a thin, polymeric microporous support containing a metal-ion complexing agent within the pores. Metal ions present in the rinse solutions are transported across these membranes and can be conc...
An Adsorbent based treatment system is presented for toxic metal removal from rinsewater streams. The adsorbent is a Mg-A1 oxide anion exchange material with high capacity (approaching 5.5 meq/g) and strong selectivity for difficult to treat species such as Electroless plating metal chelates, Fixed Cyanides and chrome conversion solutions. Data is presented describing treatment of various metal...
Very often electroless electrolytes contribute to wastewater treatment problems. These electrolytes are used in electroless plating processes, which contain a variety of chemicals to meet special surface treatment requirements. Metal salts produce the base material for metal deposition and hypophosphite is delivering the electrons for the metal reduction process – it is basically the internal e...
Advanced hybrid microelectronics require high performance packaging materials and components. Alumina, the most widely used ceramic material in microelectronics, is being replaced by new high performance materials such as aluminum nitride (AlN) and beryllia (BeO). AlN's thermal conductivity is an order of magnitude greater than alumina and it has a thermal expansion coefficient very close to si...
