Understanding the impact of snow's reflectance

To help improve the accuracy of climate models, an international team involving the National Physical Laboratory (NPL) has measured the reflectance of rough, snow-covered surfaces at large solar zenith angles.

Dynamic calibration of pressure sensors for engines

The characterisation of the pressure sensors used to develop the next generation of petrol and diesel engines is crucial to optimising their design, improving efficiency and reducing emissions. The National Physical Laboratory ...

3-D printing of microwave circuits

The National Physical Laboratory (NPL) has recently assisted Imperial College London to investigate the design, fabrication and testing of waveguides manufactured using 3D-printing techniques, by providing the underpinning ...

Supporting the rollout of hydrogen energy

As the UK's first renewable hydrogen refuelling station opens, the Gas Metrology team at the National Physical Laboratory (NPL) is supporting the rollout of hydrogen vehicles through its hydrogen purity laboratory, which ...

Exploring catalytic reactions at the nanoscale

The National Physical Laboratory (NPL) has used a novel imaging capability - tip-enhanced Raman spectroscopy - to map catalytic reactions at the nanoscale for the first time.

New tests provide assurance to MRI-guided radiotherapy

Researchers from the National Physical Laboratory (NPL), VSL and the University of Michigan have taken a crucial step towards accurate dosimetry for MRI-guided radiotherapy - a state-of-the-art cancer treatment.
