Scientists have moved quantum optic networks a step closer to reality. The ability to precisely control the interactions of light and matter at the nanoscale could help such a network transmit larger amounts of data more quickly and securely than an electrical network.
In the face of the need to set international standards for the use of quantum technologies in science and industry, a consortium formed by 14 organizations from 6 countries, led by the Hudson Institute based in Washington, D.C., has prepared two recommendations.
Research from North Carolina State University has demonstrated a new technique that converts carbon fibers and nanotubes into diamond fibers at ambient temperature and pressure in air using a pulsed laser method.
The sensor is made up of a series of gold disk-shaped nanoparticles on a glass slide. The team at Bath discovered that when they shone an infra-red laser at a precise arrangement of the particles, they started to emit unusual amounts of ultra violet (UV) light.

Lens coatings are an essential part of high-power CO2 laser systems. Coatings must protect the lens and allow for the highest levels of optical performance, with low levels of absorption and a long-life expectancy. Transparency is another coveted characteristic for use with visible HeNe red laser pointers. The cost/benefit ratio of a coating must also be considered, as well as the environmental impact of the substrates used. For optical manufacturers, the challenge is in developing a lens coating that excels in all these areas. This white paper discusses the development of anti-reflection (AR) lens coatings for use in high-power lasers.
Lasers are increasingly deployed in manufacturing applications, being pushed to higher and higher output powers and smaller and smaller beam sizes to work faster and with higher precision. Determining the beam profile at the beam focus of these lasers is critical to verify and improve manufacturing product quality. However, there are enormous challenges that must be overcome to capture the beam profiling data. This white paper discusses best practices for analyzing small, high power beams at focus for manufacturing applications.
Progress in understanding the lipid bilayer – an ingenious two-molecule thick oily barrier that protects all living cells, including our own – has been dramatic over the past 100 years. But there are still puzzles to be solved such as how these membrane proteins, which are oily themselves, navigate the oily lipid bilayer to go about their work. The first step for scientists is to figure out the thermodynamic rules that govern protein assembly in membranes.
Applying physics to the properties and underlying structures of the molecules of life offers an insight into the mechanisms that make living beings tick. But even seemingly simple actions like muscle contraction involve a wide array of biological interactions, which has shrouded the dynamics and function of individual molecules behind a curtain of complexity. The scientific community has developed a powerful toolbox of methods to probe these interactions over the past two decades, uncovering previously hidden information about the structure, dynamics and function of individual biomolecules.
