Nanorobots show collective movements similar to those found in nature, such as birds flying in flocks, or the orderly patterns that schools of fish follow.
Researchers have created micron-sized shape memory actuators that enable atomically thin two-dimensional materials to fold themselves into 3D configurations. All they require is a quick jolt of voltage. And once the material is bent, it holds its shape - even after the voltage is removed.
Using a conductive atomic force microscope, scientists scanned the solar cell surfaces and detected tiny, nanometre-sized channels for the detrimental dark currents, which are due to disorder in the a-Si:H layer.
Researchers have unveiled a novel system, capable of producing hydrogen and electricity quickly and effectively while eliminating carbon dioxide emissions significantly.
Researchers have developed hybrid nanostructured particles that can be magnetically guided to the tumor, tracked by their fluorescence and pushed to release the drug on demand by ultrasound. This technology can help make cancer chemotherapy more targeted.
