Longwave pass filters block short wavelengths of light, allowing for their use in optical filters near infrared wavelengths. Improved observation of tumour cells With new work on bio-imaging techniques, this could lead to better views of tumour cells, or of the response of the whole body to certain drugs. A team at the German Research […]
Ozone detection is an important aspect of testing both outdoor and indoor air quality; but how can it be made more accessible to the population in general? EVERYAWARE Project The solution, according to the EU’s EVERYAWARE project, could be to enable ozone detection via Bluetooth, with portable sensors wirelessly connected to people’s smartphones. A team […]
Oxygen sensors have an important role to play in treating head injuries, as leaving the brain starved of oxygen for any length of time can have catastrophic consequences. But alongside oxygen sensors, xenon detectors could also become an important component in assessing indoor air quality in facilities where people who have suffered head injuries are […]
Indoor air quality sensors could be an important tool in many European public buildings in the years to come, as part of EU-wide efforts to monitor air pollution. Tracking air pollution hot spots The PASODOBLE project has developed a system called Myair, which can provide information about air quality to hospitals and doctors, environmental officials […]
Optical bandpass filters can allow static and dynamic imaging of viscous materials using a technique similar to that already used in the detection of some cancers, according to researchers. Early detection of abnormalities Tissue abnormalities such as malignant lymph nodes in the breast can be detected using optical bandpass filters to create three views of […]
Fluorescence filters could make recycling plastics of different types substantially easier in the years to come. Faster sorting for recycling According to scientists at Ludwig-Maximilians-Universitaet (LMU) in Munich, the solution to sorting plastics faster and more easily for recycling could be to expose them to a brief flash of light. When this is done, the […]
Observing young stars using the UK Infra-Red Telescope has allowed astronomers to see some that have never been witnessed before, by effectively seeing through the dust and gas of the Milky Way. Proto-stars revealed Using optical filters near infrared, false-colour images of several of these proto-stars have been created and published by the University of […]
