Scientists have developed a new class of molecular motors that rotate unidirectionally at speeds of up to 1 kHz when exposed to sunlight at room temperature. This unique combination of features opens up novel applications in nano-engineering.
This week, an international group of scientists is reporting a breakthrough in the effort to characterize the properties of graphene noninvasively while acquiring information about its response to structural strain.
Researchers have invented a method for producing inexpensive and high-performing wearable patches that can continuously monitor the body's vital signs for human health and performance tracking, potentially outperforming traditional monitoring tools such as cardiac event monitors.
Using the latest laser techniques, many surfaces of existing products can be accurately treated. The technique can replace the special coatings that are currently applied to existing materials for surface improvement.
Researchers have for the first time developed a technique that coats anticancer drugs in membranes made from a patient's own platelets, allowing the drugs to last longer in the body and attack both primary cancer tumors and the circulating tumor cells that can cause a cancer to metastasize. The work was tested successfully in an animal model.
Researchers have created the first entropy-stabilized alloy that incorporates oxides - and demonstrated conclusively that the crystalline structure of the material can be determined by disorder at the atomic scale rather than chemical bonding.
Neurons thrive and grow in a new type of nanowire material. In time, the results might improve both neural and retinal implants, and reduce the risk of them losing their effectiveness over time, which is currently a problem.
Scientists have created an innovative tool to directly detect the delicate, single-molecule interactions between DNA and enzymatic proteins. Their approach provides a new platform to view and record these nanoscale interactions in real time.
Using nanometer-scale components, researchers have demonstrated the first optical rectenna, a device that combines the functions of an antenna and a rectifier diode to convert light directly into DC current.
Material researchers are developing a procedure that allows them to mimic the complex fine structure of biological composite materials, such as teeth or seashells. They can thus create synthetic materials that are as hard and tough as their natural counterparts.
