Photonic Wheels: for Drag Racing at Nano Scale

Optical tweezers will soon be more agile than ever before since light beams can now induce a rolling movement onto a nanoscale object, in addition to pushing it along a surface. Optical tweezers and spanners are about to become more sophisticated. A group of physicists in Germany has just demonstrated, for the first time, the existence of a novel, transverse effect pertaining to light beams used for optical trapping, called photonic wheel.

High-Resolution Imaging: Quantum Dot Technique Combines Best of Optical and Electron Microscopy

Researchers working at the National Institute of Standards and Technology (NIST) have developed a new microscopy technique that uses a process similar to how an old tube television produces a picture-cathodoluminescence-to image nanoscale features. Combining the best features of optical and scanning electron microscopy, the fast, versatile, and high-resolution technique allows scientists to view surface and subsurface features potentially as small as 10 nanometers in size.

Seeing Is Believing – Imaging the Processes of Life

The symposium "Seeing is Believing - Imaging the Processes of Life" will take place at the EMBL Advanced Training Centre, Heidelberg, Germany from October 3 - 6, 2013. With the symposium we aim to bring together the leading developers of imaging methods with cutting edge applications that illustrate how imaging can answer biological questions. We will place emphasis on methods that are able to capture the dynamics of life and aim to span the whole range from molecular resolution to imaging of whole organisms.

Transforming Optics with Metamaterial Flexible Sheets

New ultrathin, planar, lightweight, and broadband polarimetric photonic devices and optics could result from recent research by a team of Los Alamos National Laboratory scientists. The advances would boost security screening systems, infrared thermal cameras, energy harvesting, and radar systems. This development is a key step toward replacing bulky conventional optics with flexible sheets that are about the thickness of a human hair and weighing a fraction of an ounce. The advance is in the design of artificially created materials, called metamaterials, that give scientists new levels of control over light wavelengths. The research was reported online in Science.

Seeing Inside a Molecule Using Light

An international team, with the participation of the Donostia International Physics Center (DIPC) and the Centre of Materials Physics (CSIC-University of the Basque Country [UPV/EHU]), has managed to resolve and identify, with a hitherto unprecedented resolution, a single organic molecule using light. The journal Nature published and highlighted the research work, which opens doors to possible technological applications in photochemistry and nanotechnology.

New Imaging Tool Directly Measures Liquid Surfaces

New Imaging Tool Directly Measures Liquid Surfaces

A unique chemical imaging tool readily and reliably presents volatile liquids to scientific instruments, according to a team including Pacific Northwest National Laboratory. These instruments require samples be held in a vacuum, which is often incompatible with hydrocarbons and other liquids. Designed and built at PNNL, this one-of-a-kind sample holder continuously pumps the liquid through a gold-coated microfluidic chamber. The extremely narrow channel provides high linear velocity at the detection window and helps overcome the liquids' tendency to vaporize. Instruments access the liquid via an open viewing port. Tests with electron microscopes and mass spectrometers prove the device can operate continuously for up to 8 hours. Further, the device handles complex liquids.
