Recent experiments have confirmed* that a technique developed several years ago at the National Institute of Standards and Technology (NIST) can enable optical microscopes to measure the three-dimensional (3-D) shape of objects at nanometer-scale resolution—far below the normal resolution limit for optical microscopy (about 250 nanometers for green light).
EPFL researchers have developed a theoretical method that uses optomechanics to amplify weak signals.
Light is a slippery fellow. Stand in a darkened hallway and close a door to a lighted room: Light will sneak through any cracks — it doesn't want to be confined. "Typically, in free space, light will go everywhere," graduate student Chia Wei (Wade) Hsu says. "If you want to confine light, you usually need some special mechanism."
A research group led by Professor Hiroyuki Noji, Department of Applied Chemistry, Graduate School of Engineering, University of Tokyo, successfully observed and touched the rotational motion of a 1-nm synthetic molecular machine through the application of a single-molecule capturing and manipulation technique using optical microscopy and a bead probe (single-molecule motion capturing), which allows visualization of molecular mechanical motion.
Robert Candler, assistant professor of electrical engineering at the UCLA Henry Samueli School of Engineering and Applied Science, has received a $1 million research grant from the W. M. Keck Foundation to develop an ultra-compact X-ray free electron laser.
Ever heard of the water window? It consists of radiations in the 3.3 to 4.4 nanometre range, which are not absorbed by the water in biological tissues. New theoretical findings show that it is possible to develop coherent radiations within the water window.
The invention of fibre optics revolutionized the way we share information, allowing us to transmit data at volumes and speeds we'd only previously dreamed of.
The invention of fibre optics revolutionized the way we share information, allowing us to transmit data at volumes and speeds we’d only previously dreamed of. Now, electrical engineering researchers at the University of Alberta are breaking another barrier, designing nano-optical cables small enough to replace the copper wiring on computer chips.
A research group led by Dr. Hirokazu Komatsu, a member of the YAMATO-MANA Program and a researcher at the International Center for Materials Nanoarchitectonics (MANA; Director General: Masakazu Aono) of the National Institute for Materials Science (NIMS; President: Sukekatsu Ushioda), and Dr. Katsuhiko Ariga, MANA Principal Investigator and Supermolecules Unit Director, in collaboration with postdoctoral researcher Dr. Eri Adams and unit leader Dr. Ryoung Shin of the RIKEN Center for Sustainable Resource Science, have developed a novel method for imaging cesium distributions in plant cells. Prior to this work, imaging of cesium distributions in plant cells had not been available.
Kansas State University physicists and computer scientists are involved in a collaborative project to understand a long-lasting mystery: how light interacts with matter.
