Scientists at the National Physical Laboratory (NPL), Teddington, Middlesex, UK have good news for manufacturers and users across the optical instrumentation industry. Based on existing processes developed in the US and Japan, a team of researchers at NPL has developed a new technique for commercial manufacturing of ultra-black coatings, which represent one of the blackest, lowest reflectance surfaces developed so far.
Performance of optical instrumentation depends on the quality of materials used in their manufacture. For the accuracy of measurement in the ultra-violet, infra-red and visible regions, optimal radiation detection and minimisation of stray light is crucial.
By studying the effect of different methods of chemical etching on various compositions of nickel-phosphorous alloys, researchers have come up with the most effective commercially available black coating to date. With reflectance as low as 0.35% in the visible region, the coating, known as NPL Super Black or Ni-P black – as it is based on a nickel -phosphorous compound – is set to have a major impact in fields such as radiometry, spectroscopy, optical metrology, and within the aerospace and defence industries.

Researchers at the University of New Hampshire have captured a difficult-to-view singular event involving "magnetic reconnection"--the process by which sparse particles and energy around Earth collide producing a quick but mighty explosion--in the Earth's magnetotail, the magnetic environment that trails behind the planet.
Magnetic reconnection has remained a bit of a mystery to scientists. They know it exists and have documented the effects that the energy explosions can...
Biochips have been developed at TU Wien (Vienna), on which tissue can be produced and examined. This allows supplying the tissue with different substances in a very controlled way.
Cultivating human cells in the Petri dish is not a big challenge today. Producing artificial tissue, however, permeated by fine blood vessels, is a much more...
Faster and secure data communication: This is the goal of a new joint project involving physicists from the University of Würzburg. The German Federal Ministry of Education and Research funds the project with 14.8 million euro.
In our digital world data security and secure communication are becoming more and more important. Quantum communication is a promising approach to achieve...
On Saturday, 10 November 2018, the research icebreaker Polarstern will leave its homeport of Bremerhaven, bound for Cape Town, South Africa.
When choosing materials to make something, trade-offs need to be made between a host of properties, such as thickness, stiffness and weight. Depending on the application in question, finding just the right balance is the difference between success and failure
Now, a team of Penn Engineers has demonstrated a new material they call "nanocardboard," an ultrathin equivalent of corrugated paper cardboard. A square...
