A new deep-learning AI tool for analysing images of complex nanoparticles

Nanoparticles (NPs), due to their small size (1-100 nm), have enhanced activity compared to the same material of larger sizes and are finding uses in a range of products and processes, including cosmetics, sunscreens and water treatment. It is estimated that the global market for NPs is €20 billion – with over 300 000 European ...

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...

Quantifying the uncertainty of Electric Properties Tomography in medical imaging

Magnetic Resonance Imaging (MRI) is a diagnostic, mainly qualitative, technique used to visualise the soft tissues of a patient. The application of a strong magnetic field causes the protons in a patient’s hydrogen atoms to align with it. Radiofrequency pulses are then used to force the protons to move out of and back into alig...

Image showing that every measurement has a degree of uncertainty

Advancing the evaluation of measurement uncertainty

Measurements underpin almost all areas of modern life, including trade, industrial manufacture, environment and health. However, no measurement is perfect — factors such as the instrument type, operator, measurement method or the environment can affect the returned results. All these factors combine to produce a ‘measurement un...

Improving the measurement of gloss

The EU accounts for around 15 % of the world’s international trade in goods. Purchases are heavily influenced by conscious and subconscious visual cues which we relate as ‘quality’ in a product. A poor finish on a car, for example, may cause paint to develop an ‘orange peel’ look, eliciting a negative response in a buyer. This ...

New photometry standards for measurement of solid-state lighting products

Conventionally the calibration of photometric equipment was performed with tungsten filament standard lamps with the standard illuminant A spectrum, which was published by the International Commission on Illumination (CIE) in 1931 and was originally designed for use with incandescent lighting products. However, incandescent co...
