Diamond Nitrogen-vacancy Centers Power World’s Smallest Radio Receiver

nitrogen-vacancy centers

A tiny radio whose building blocks are the size of two atoms has been developed by Researchers from the Harvard John A. Paulson School of Engineering and Applied Sciences. Built out of an assembly of atomic-scale defects in pink diamonds, it is the world’s smallest radio receiver. The device can withstand extremely harsh environments and …

Meter-scale Optical Coherence Tomography Depth Barrier Broken

3d optical coherence tomography

The first ever optical coherence tomography (OCT) images of cubic meter volumes have been produced, through an industry-academic collaboration. The advance could open up many new uses for OCT in industry, manufacturing and medicine. It also marks a milestone toward developing a high-speed, low-cost optical coherence tomography system on a single integrated circuit chip. James …

Femtosecond Laser Pulse Control Of Electron Microscope Nanotips

femtosecond nanotips

A method of controlling electron emissions with higher precision than ever before has been developed by researchers at Vienna University of Technology, together with colleagues from the FAU Erlangen-Nürnberg in Germany. In an electron microscope, electrons are emitted by pointy metal tips, so they can be steered and controlled with high precision. Recently, such metal …

Measuring Microscale Granular Crystal Dynamics

granular-crystals

For the first time ever, mechanical engineers have succeeded in analyzing interactions between microscale granular crystals. Designing materials that better respond to dynamic loading could help vehicles minimize vibration, better protect military convoys or potentially make buildings safer during an earthquake. Granular materials are assemblages of particles that range broadly from powders to sand to …
