An international group of researchers shed light on oxygen's role in enhancing red LEDs and reported that the quantity and location of oxygen in gallium nitride (GaN) can be fine-tuned to improve the optical performance of europium-doped GaN devices.
Scientists have developed a new approach in enhancing catalytic performance. They report functionalised, self-assembled nanospheres that enable highly efficient catalytic conversion by acting as 'nanocentrators'.
A technique that combines the ultrasensitivity of surface-enhanced Raman scattering (SERS) with a slippery surface will make it feasible to detect single molecules of a number of chemical and biological species from gaseous, liquid or solid samples. This combination of slippery surface and laser-based spectroscopy will open new applications in analytical chemistry, molecular diagnostics, environmental monitoring and national security.
A two-stage power management and storage system could dramatically improve the efficiency of triboelectric generators that harvest energy from irregular human motion such as walking, running or finger tapping.
Malaysian scientists are joining forces with Harvard University experts to help revolutionize the treatment of lung diseases - the delivery of nanomedicine deep into places otherwise impossible to reach.
