New X-ray imaging technique to study the transient phases of quantum materials
An international team of researchers has demonstrated for the first time the use of a new lensless ultrafast X-Ray method to image phase transitions
27-Dec-2022 - The use of light to produce transient phases in quantum materials is fast becoming a novel way to engineer new properties in them, such as the generation of superconductivity or nanoscale topological defects. However, visualizing the growth of a new phase in a solid is not easy, due in-part to ...
Tapping hidden visual information: An all-in-one detector for thousands of colours
A new chip from Aalto University researchers puts photonic information at our fingertips
27-Oct-2022 - Spectrometers are widely used throughout industry and research to detect and analyse light. Spectrometers measure the spectrum of light – its strength at different wavelengths, like the colours in a rainbow – and are an essential tool for identifying and analysing specimens and materials. ...
Developing an optical methodology for rapid detection of COVID-19
The new tool has made it possible to detect SARS-CoV-2 in exudate from symptomatic patients with a sensitivity of 100% and a specificity of 87.5%
21-Feb-2022 - This new methodology, whose first results are published in Scientific Reports, has obtained a sensitivity of 100% and a specificity of 87.5% in the detection of SARS-CoV-2 in nasopharyngeal exudate (the same samples used in a PCR test) from symptomatic people. It has also been possible to detect ...
Deep Vision: Near-infrared imaging and machine learning can identify hidden tumors
Near-infrared hyperspectral imaging combined with machine learning can visualize tumors in deep tissue
05-Feb-2021 - Tumors can be damaging to surrounding blood vessels and tissues even if they're benign. If they're malignant, they're aggressive and sneaky, and often irrevocably damaging. In the latter case, early detection is key to treatment and recovery. But such detection can sometimes require advanced ...
