Dissemination of accurate time and frequency over ground-based optical systems

Almost all areas of modern life require an accurate knowledge of time, synchronised to a common time source. In Europe, time and frequency signals, and hence positioning information, are provided by radio signals or the European Space Agency’s (ESA) Galileo network of 30 satellites orbiting 20 000 km above the Earth equipped wi...

A new ISO standard on the identification of nanoparticles

Nanoparticles (NP), defined as having one or more dimension of 1-100 nm, are used in a range of modern products, including cosmetics, sunscreen, coatings for solar cells, and materials for water treatment. A factor for their extensive use is the greater chemical activity imparted by their large surface area relative to their si...

Consumer trust increased by new reference device

The energy grid is becoming increasingly more decarbonised. However, renewable energy sources are more variable compared to conventional energy sources, resulting in a great need to develop the metrological network required to control and monitor the energy grid. The changes in the energy grid system have also resulted in a nee...

Thermal diffusivity measurements at high temperatures for space launcher engines

Industries increasingly rely on running their operations at high temperatures, up to 3000 °C, to increase the efficiency and reduce environmental footprint. However, before the Hi-TRACE project there was a metrological need for accurate thermophysical properties measurements with assessed measurement uncertainties. In the spac...

A low-cost 3D Large Volume Metrology system for the factories of the future

Even relatively small passenger planes have wingspans and fuselages exceeding 35 m in length, and larger, more modern aircraft can exceed 50 m or more. Due to the size of components in aviation, and many other industries, these must be correctly assembled, tracked and error mapped or ‘calibrated’ in situ. To do this requires th...

Measuring nanoparticle shell thickness

Nanoparticles are becoming increasingly used in a wide range of areas, and thus are expected to soon have a significant economic and environmental impact. In health they are used for targeted drug delivery, and in the energy sector they are used in photovoltaic technologies to improve solar cell efficiency compared to conventio...
