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.

For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.
In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...

For photographers and scientists, lenses are lifesavers. They reflect and refract light, making possible the imaging systems that drive discovery through the microscope and preserve history through cameras.
But today's glass-based lenses are bulky and resist miniaturization. Next-generation technologies, such as ultrathin cameras or tiny microscopes, require...
Scientists from the University of Zurich have succeeded for the first time in tracking individual stem cells and their neuronal progeny over months within the intact adult brain. This study sheds light on how new neurons are produced throughout life.
The generation of new nerve cells was once thought to taper off at the end of embryonic development. However, recent research has shown that the adult brain...
