Combining scanning probe technologies with microbeads for low-cost, high-resolution optical lithography systems

NanoWerk.com - Wed, 10/04/2017 - 12:20
Among the important parameters in optical lithography is the spatial resolution you can get and the time you need to draw your pattern. Systems with regular and fixed patterns can be extremely fast but those systems are based on masks. Mask production is a time consuming and expensive process. So-called mask-less systems can draw unorganized patterns directly on substrates, at the cost of longer process times. Researchers now have presented a new lithographic approach with a high-resolution, low-cost technique based on nanosphere lithography.

Electrode layer prepared from activated carbon (from tea leaves) enhances fuel cell performance by 33%

NanoWerk.com - Tue, 10/03/2017 - 13:57
Chemical engineering researchers have reported the usage of activated carbon prepared from tea leaves, improving the mass transport phenomenon (33 % performance improvement) in an operating direct methanol fuel cell, owing to its pore structure characteristics. The cell performance underwent drastic changes in the mass transport region of the fuel cell polarization curve, comparable to the standard membrane electrode assembly. This is attributed to the pore structure of this framework aiding in enhanced water removal, as a result more air molecules react with the platinum catalyst sites finally improving the fuel cell performance.
