Future standard for solar irradiance delivered to Switzerland

Scientists from the National Physical Laboratory (NPL) have installed a Cryogenic Solar Absolute Radiometer (CSAR) at the Physikalisch-Meteorologisches Observatorium Davos World Radiation Center (PMOD/WRC) in Switzerland. ...

Bio-standards for high-resolution microscopy

Modern microscopes use in-built magnification scales for routine calibration. However, recent advances in high-resolution technologies and a clear shift towards more automated systems challenge the accuracy of such scales ...

Towards the ultimate model of water

Researchers from the National Physical Laboratory (NPL), IBM and the University of Edinburgh have developed the first conceptually simple but broadly applicable model for water.

Reference biosensor developed for calibrating diagnostic devices

Researchers at the National Physical Laboratory (NPL), in collaboration with Chalmers University of Technology, Sweden, and the University of Tampere, Finland, have developed a novel reference biosensor to aid the development ...

New method provides direct SI traceability for sound pressure

Scientists at the National Physical Laboratory (NPL) - the UK's National Measurement Institute - have developed an optical method for remotely measuring sound pressure inside a fully anechoic chamber which is the first to ...

Quantum model helps solve mysteries of water

Water is one of the most common and extensively studied substances on earth. It is vital for all known forms of life but its unique behaviour has yet to be explained in terms of the properties of individual molecules.

New insight into improving air quality measurements

Researchers from the National Physical Laboratory (NPL) and King's College London have identified a mechanism which is responsible for under-reporting of peak nitrogen dioxide concentrations at some air quality monitoring ...
