| Unprecedented view of a single catalyst nanoparticle at work Posted: 01 Oct 2021 12:27 PM PDT A research team has been using high-intensity X-rays to observe a single catalyst nanoparticle at work. The experiment has revealed for the first time how the chemical composition of the surface of an individual nanoparticle changes under reaction conditions, making it more active. This study marks an important step towards a better understanding of real, industrial catalytic materials. |
| Low-cost, portable device could diagnose heart attacks in minutes Posted: 01 Oct 2021 10:02 AM PDT Researchers have developed a sensor that could diagnose a heart attack in less than 30 minutes, according to a new study. |
| Virtual care with remote monitoring catches drug errors and reduces patient pain Posted: 30 Sep 2021 05:24 AM PDT The study looked at patient outcomes from virtual care and remote automated monitoring (RAM) -- video calls with nurses and doctors, and self-monitoring of vital signs using wearable devices. Half of 905 post-surgery patients at nine sites in Hamilton, Kingston, London, Ottawa and Edmonton in Canada were randomized to use technology at home -- a cellular tablet and RAM equipment to measure their heart rate, blood pressure, oxygen saturation, respiration rate, body temperature and weight -- for 30 days after they left the hospital. |
