Detecting food and cosmetic spoilage and contamination. Identifying new medicinal plants in a remote jungle. Authenticating tea and wine. Scientists have developed a low-cost, portable, paper-based sensor that can potentially carry out all of these functions with easy-to-read results.
Researchers improved perovskite-based technology in the entire energy cycle, from solar cells harnessing power to LED diodes to light the screens of future electronic devices and other lighting applications.
Researchers have discovered a new reaction mechanism that could be used to improve catalyst designs for pollution control systems to further reduce emissions of smog-causing nitrogen oxides in diesel exhaust.
