Using gold nanoparticles and a thin layer organosilanes, Jan Genzer and associates from North Carolina State University, developed a new material that could be used to make better filters, more efficient sensors, and faster catalysts. "The distinguishing feature of our approach is that the particles follow a pre-designed chemical template provided by the organosilane sticky groups," said Genzer. "The ability to manipulate the underlying template allows us to prepare gradient structures of nanoparticles with varying characteristics." To build the substance, Genzer prepares a very thin layer of organosilanes, sticky molecules with a head and a tail, on a rectangular surface of silica. The head glues to the surface, while the tail sticks out, acting like a hook waiting for a gold nanoparticle to attach to it. The scientists dip the material in a solution containing negatively charged gold nanoparticles.

The 3D printing revolution seems to have a knack for quickly moving technology ahead by way of collaborative effort and even a little friendly competition -- all of course in the name of scientific advancement.
Advantech has launched a new series of motion-control I/O modules to meet the increased demands that come with more distributed industrial systems that require control of a growing number of axes and devices.
A quick look into the merger of two powerhouse 3D printing OEMs and the new leader in rapid prototyping solutions, Stratasys. The industrial revolution is now led by 3D printing and engineers are given the opportunity to fully maximize their design capabilities, reduce their time-to-market and functionally test prototypes cheaper, faster and easier. Bruce Bradshaw, Director of Marketing in North America, will explore the large product offering and variety of materials that will help CAD designers articulate their product design with actual, physical prototypes. This broadcast will dive deep into technical information including application specific stories from real world customers and their experiences with 3D printing. 3D Printing is
