Researchers Optimize 3D Printing of Optically Active Nanostructures

Trial-and-error procedure becomes unnecessary

19-Jan-2024 - The shape, size and optical properties of 3-dimensional nanostructures can now be simulated in advance before they are produced directly with high precision on a wide variety of surfaces. For around 20 years, it has been possible to modify surfaces via nanoparticles so that they concentrate or ...

Researchers develop new 3D printing for the direct production of nanostructures

14-Nov-2019 - A team from Graz University of Technology succeeded in using the FEBID method to produce complex 3D-printed nano-components for the first time without additional support structures. In the nanometer range, complex, free-standing 3D architectures are very difficult to produce in a single step due ...

Forces that align crystals and help them snap together measured

03-May-2017 - Like two magnets being pulled toward each other, tiny crystals twist, align and slam into each other, but due to an altogether different force. For the first time, researchers have measured the force that draws them together and visualized how they swivel and align. Called van der Waals forces, ...

NREL research advances understanding of photoelectrodes

10-Dec-2015 - Scientists at the Energy Department's National Renewable Energy Laboratory (NREL) have developed a new probe that could lead to a better photoelectrochemical cell. Ye Yang and Jing Gu are lead authors of the paper. NREL colleagues, James Young, Elisa Miller, John Turner, Nathan Neale and Matthew ...

3D IR images now in full color

Berkeley Lab and University of Wisconsin researchers unveil FTIR spectro-microtomography

07-Aug-2013 - An iconic moment in the history of Hollywood movie magic was born in the 1939 film The Wizard of Oz when Judy Garland as Dorothy Gale stepped out of the black and white world of Kansas into the rainbow colored world of Oz. An iconic moment in the history of infrared imaging may have been born ...

Nanometer-scale diamond tips improve nano-manufacturing

A diamond tip lives forever

15-Nov-2012 - One of the most promising innovations of nanotechnology has been the ability to perform rapid nanofabrication using nanometer-scale tips. The fabrication speed can be dramatically increased by using heat. High speed and high temperature have been known to degrade the tip… until now. "Thermal ...
