EPFL-led Researchers Successfully Produce Light Pulses with Small Chip-Based Device

Solitons are a type of wave that, unlike other waves, retains its shape even as it moves further away from its source. Soliton waves of light are of great interest because they can produce evenly spaced frequencies of light, like the teeth of comb.

Simplified Nanotechnology Approach to Fabricating Ultrathin Optics

Simplified Nanotechnology Approach to Fabricating Ultrathin Optics

Researchers from the University of Illinois at Urbana-Champaign have developed a simplified approach to fabricating flat, ultrathin optics. The new approach enables simple etching without the use of acids or hazardous chemical etching agents.

Researchers Determine Structure of Water-Soluble Gold Nanoparticles in Solution

Scientists have successfully measured the dynamical behavior of the organic ligand layer of gold nanoparticles in water. This provides a better understanding of the structure of nanometer-scale gold particles in solution, and will allow the creation of controllable strategies for the functionalization of ligated nano-sized particles for a variety of applications. Researchers from the Colorado State University, USA and the University of Jyväskylä, Finland were involved in the study, and the results have been published in Nature Communications.

MIT Researchers Develop Nanophotonic Technology that Makes Incandescent Bulbs More Efficient

A team of scientists from MIT and Purdue University has developed a novel technology that combines the warm look of conventional incandescent light bulbs with improved energy efficiency. This latest breakthrough could potentially revive the century-old incandescent bulbs.

Nanoparticle Technique Developed that Identifies Single Molecules

Nanoparticle Technique Developed that Identifies Single Molecules

A new method of increasing the signal of Surface-Enhanced Raman Scattering (SERS) has been developed which means samples of just a few molecules can be identified and studied in a non-destructive way. SERS is an enhanced form of Raman Spectroscopy, a technique which uses infra-red lasers to determine the molecular constituents of a sample without causing any permanent changes.

Rice University Researchers Develop Light-Driven, Single-Molecule Nanosubmarines

Rice University Researchers Develop Light-Driven, Single-Molecule Nanosubmarines

Nanoscale submarines, made of only 224 atoms and driven by ultraviolet light, have been developed. It is hoped that this technology can be further developed to allow the transport of molecular cargoes or the delivery of drugs to diseased organs.

NASA Develop Spherical Occulter using Super-Black Carbon-Nanotube Coating to Study the Sun’s Corona

NASA Develop Spherical Occulter using Super-Black Carbon-Nanotube Coating to Study the Sun’s Corona

A team of NASA scientists are working on the development of an occulter, which blocks light from the sun, for use in a CubeSat mission to measure the sun's coronal mass ejections. To assist in the production of the occulter the researchers have been using carbon nanotubes to achieve the full absorption of light

New Method of Producing Infrared Cameras Developed that can Detect Individual Wavelengths

New Method of Producing Infrared Cameras Developed that can Detect Individual Wavelengths

​A novel technology that uses silver nanocubes to bring true color to infrared cameras has been developed which can 'see' in the visible and infrared radiation. This is an improvement on current technology that only measures the intensity of infrared radiation and not the specific frequencies.
