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.
Scientists determined that the electric field is responsible for alterating the fracture toughness of nanomaterials, which are used in state-of-the-art electronic devices. It is the first observed evidence that the electric field changes the fracture toughness at a nanometer scale.
Tandem solar cells based on silicon and perovskites have raised high hopes for future high efficiency solar modules. Researchers have now shown that an ultimate efficiency of 30% should be attainable with such tandem cells.
