In this article the progresses in the synthesis of hierarchical zeolite with mesopores are reviewed,emphatically on the alkaline-tailored method,synthesis within lim.

Some new processes and technologies for electronics finishing were introduced, such as wafer plating, electrochemical mechanical polishing, microelectro-mechanical system plating, copper plating using insoluble anode, platinized niobium electrode, lead and cadmium free eleclroless nickel, recycling of alkaline etching solution and reclaiming system of copper.

Some experimental methods for the treatment of ammonia etching wastewater are introduced.
