In this talk, we report a research work on fabrication and metallization of high aspect ratio polymer microstructures fabricated using UV lithography of SU-8 on silicon substrate. Electroless plating of metal film on both the top and sidewall surfaces of microstructures were achieved while the silicon substrate was not plated. The primary chemical mechanisms and possible applications were also ...

Functional plating such as alloys or dispersion coatings have been widely used in metal finishing industry. In general, dispersion coatings are deposited from plating baths containing suspended particles such as metal oxides, carbides, metals or organic materials,(l-3) Codeposited particles in the dispersion coatings have the remarkable influence on the properties of the deposits depending on t...

background: the occurrence of heavy metals in the environment is of important concern due to their toxicity and health effects on humans, including cancer. because metals have been extensively used for centuries in commerce, environmental contamination is widespread; moreover, exposure to metals and metal compounds continues to be a significant public health problem. electroplating sludge conta...

Electroless nickel plating is a widely used plating method in many industries. The usability of the coating is, however, restricted by the control problems related to the electroless nickel plating process. To ensure deposit quality, the transcendent properties of electroless nickel deposit should be accurately controlled during plating, which is challenging because of the spontaneous, unstable...

Owning to their very high theoretical capacity, lithium metal anodes are expected to fuel the extensive practical applications in portable electronics and electric vehicles. However, unstable solid electrolyte interphase and lithium dendrite growth during lithium plating/stripping induce poor safety, low Coulombic efficiency, and short span life of lithium metal batteries. Lately, varies of mic...

The chrome plating industry is one of the highly polluting industries whose effluent mainly consists of chromium(VI). This compound is highly toxic to aquatic life and human health. The rinse water constituents reflect the chrome plating bath characteristics; generally dead tank wash water contains about 1% of the plating bath concentration. Other metals and metal compounds usually considered a...

The need to better understand whisker growth has dramatically increased as component suppliers convert from tin-lead (SnPb) finishes to Pb-free finishes of Sn and low-alloy-content Sn-based finishes. Whiskers are spontaneous growth of metal filaments emanating from the finish surface. The issues with whiskers are they may grow long enough to cause short circuiting or break off and interfere wit...
