Vivid holographic images and text can now be produced by means of an ordinary inkjet printer. This new method is expected to significantly reduce the cost and time needed to create the so-called rainbow holograms, commonly used for security purposes - to protect valuable items, such as credit cards and paper currency, from piracy and falsification.
The China-UK collaborative effort to support the development an international graphene standards and testing centre was officially launched at Zhongguancun Fengtai Science Park, Beijing, China. As the demand for international standards for testing graphene increases, the Centre in Beijing will lay the foundation for the development of graphene industry and high-end applications in China.
Miniaturization is the magic word when it comes to nanomagnetic devices intended for use in new types of electronic components. Scientists now have proposed the use of ion beams for their fabrication. An ultra-fine beam consisting of around 10 neon ions suffices to bring several hundred atoms of an iron-aluminum alloy into disarray and thereby generate a nanomagnet embedded directly in the material.
An interdisciplinary research team has found a way of accessing the interior of transistors. The researchers have manipulated the electron gas contained within by applying resonators to generate rhythmic oscillation in the terahertz range inside.
Researchers have come up with a procedure that makes it possible to produce thin film tandem solar cells in which a thin perovskite layer is used. The processing of peroveskite takes place at just 50 degrees Celsius and such a process is potentially applicable for low cost roll-to-roll production in future.
Engineers have developed a new technology that uses an oscillating electric field to easily and quickly isolate drug-delivery nanoparticles from blood. The technology could serve as a general tool to separate and recover nanoparticles from other complex fluids for medical, environmental, and industrial applications.
