- Researchers found that new hollow core optical fibers experience unexpected loss of ultraviolet light, which suggests absorption by chlorine gas.
- This loss decreases over time when the fiber ends are exposed to the atmosphere, indicating a recovery of light transmission.
- Initial measurements showed a chlorine concentration of 0.45 µmol/cm in the fiber, roughly 1.1 mol% Cl at atmospheric pressure.
Article Synopsis
- The project investigates the effectiveness of ground-penetrating radar (GPR) in locating unmarked graves, comparing signals from both pig and human remains.
- Human, pig, and control graves were monitored for 17 months using a GPR system, revealing specific radar patterns associated with remains.
- The study identifies five key radar signature classes for graves, aiding in the interpretation of GPR data in future investigations and enhancing communication within the scientific community.
The OpenFlexure Microscope is an accessible, three-dimensional-printed robotic microscope, with sufficient image quality to resolve diagnostic features including parasites and cancerous cells. As access to lab-grade microscopes is a major challenge in global healthcare, the OpenFlexure Microscope has been developed to be manufactured, maintained and used in remote environments, supporting point-of-care diagnosis. The steps taken in transforming the hardware and software from an academic prototype towards an accepted medical device include addressing technical and social challenges, and are key for any innovation targeting improved effectiveness in low-resource healthcare.
