An international group of scientists has unlocked the secret of a gold-based catalyst that is responsible for a new, environmentally friendly method of producing the vinyl chloride monomer (VCM) that is used to manufacture polyvinyl chloride (PVC), the world's third-most widely used plastic.
Scientists have discovered a group of materials which could pave the way for a new generation of high-efficiency lighting, solving a quandary which has inhibited the performance of display technology for decades.
A novel electron microscope pixel array detector (EMPAD) yields not just an image, but a wealth of information about the electrons that create the image and, from that, more about the structure of the sample.
These microcarriers may offer an entirely different approach to treating solid human tumors of numerous pathologic subtypes by delivering their encapsulated drug cargo to a tumor and protecting against collateral tissue damage.
A new way to grow narrow ribbons of graphene, a lightweight and strong structure of single-atom-thick carbon atoms linked into hexagons, may address a shortcoming that has prevented the material from achieving its full potential in electronic applications.
Classical physics states that a crystal consists of perfectly ordered particles from a continuous symmetrical atomic structure. The Mermin-Wagner theorem from 1966 broke with this view: it states that in one-dimensional and two-dimensional atomic structures (for example in an atomic chain or membrane) there cannot be perfect ordering of particles over long ranges.
Researchers have developed a technique for converting positively charged (p-type) reduced graphene oxide (rGO) into negatively charged (n-type) rGO, creating a layered material that can be used to develop rGO-based transistors for use in electronic devices.
