Laser Cooling Chills Radium Ions For The First Time

Researchers have successfully used laser cooling on radium ions for the first time. Given that lasers are known for heating things up, laser cooling may seem a contradiction in terms. However, scientists have devised a way to use the technology to achieve unparalleled levels of cold. Radium is the heaviest alkaline earth element, and the…Continue readingLaser Cooling Chills Radium Ions For The First Time

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

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…Continue readingDiamond Nitrogen-vacancy Centers Power World’s Smallest Radio Receiver

Meter-scale Optical Coherence Tomography Depth Barrier Broken

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…Continue readingMeter-scale Optical Coherence Tomography Depth Barrier Broken

Femtosecond Laser Pulse Control Of Electron Microscope 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-N├╝rnberg 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…Continue readingFemtosecond Laser Pulse Control Of Electron Microscope Nanotips

Measuring Microscale Granular Crystal Dynamics

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…Continue readingMeasuring Microscale Granular Crystal Dynamics

First Nanoscale Tunable Infrared Source Unveiled

A new nanoparticle amplifier that can generate infrared light and boost the output of one light by capturing and converting energy from a second light has been demonstrated by photonics researchers at Rice University. The creation of Rice’s Laboratory for Nanophotonics (LANP), the device functions similar to a laser. While lasers have a fixed output…Continue readingFirst Nanoscale Tunable Infrared Source Unveiled
