The ZOG Method: True Printed Circuit Boards
A novel way to fabricate printed circuit boards without the need of expensive equipment or toxic chemicals. The circuit board is printed using a 3D printer and liquid metal is used for the circuit traces. Circuits are packaged with plastic and sealed by default. Multilayer PCBs can also be fabricated without the need of a multi-ton press. This m...

3-Dimensionally Reinforced Nanocomposites
BackgroundThe main advantage of composites and nanocomposites, in addition to their high specific strength and stiffness, is their ability to be tailored towards a specific loading condition, i.e., placing the load carrying fibers (or, e.g., Carbon Nanotubes, CNTs) where the loads and stresses are. Traditional composites designed for in-plane loading ...
