Researchers at the Institute for Basic Science (IBS, South Korea), in collaboration with teams from the University of Birmingham and the Korea Advanced Institute of Science and Technology (KAIST), have developed unique graphene-based lenses with tunable features. These optical devices, made of graphene and a punctured gold surface, could become optical components for advanced applications like amplitude tunable lenses, lasers (i.e. vortex phase plates), and dynamic holography.
On the quest for miniaturization, scientists at the Center for Integrated Nanostructure Physics, within the Institute for Basic Science (IBS, South Korea), in collaboration with researchers from the University of Birmingham and the Korea Advanced Institute of Science and Technology (KAIST), develop credit card-thick, flat lenses with tunable features. These optical devices, made of graphene and a punctured gold surface, could become optical components for advanced applications, such as amplitude tunable lenses, lasers (i.e. vortex phase plates), and dynamic holography.
The technology of the future is set to be lighter, more flexible and incredibly durable. But which wonder materials will get us there? From science fiction to comic books, there have been plenty of wonder materials that promise the impossible. One example is adamantium, which is supposedly indestructible.
Graphene is constantly being employed into various battery and energy storage technologies and this has become one of the largest growing areas of graphene research commercially. A team composed of academics and industry scientists from Korea have created a graphene-silica assembly, called a graphene ball, for use as an anodic material and a cathodic coating material in lithium-ion battery batteries.
The Cambridge Graphene Centre is pleased to announce the opening of two new high-specification facilities: cleanrooms for precision fabrication of electrical and optoelectronic devices and a dryroom for large-scale battery prototypes.
Researchers have uncovered a way to harness a two-dimensional material that could provide clean and potentially limitless energy. A team from the University of Arkansas discovered they could generate an alternating current, strong enough to indefinitely power a wristwatch, by utilising the unique material properties of graphene sheets.
Thin sheets of graphene may be used as light sails for spacecraft. In yet another microgravity experiment, a team of Delft PhD students examined the properties of ferrofluids in space.
Tata s looking for other collaborators, especially any organizations that can offer expertise and insight on how to scale up a steel production process that employs a graphene oxide for corrosion resistance.
Earlier this year, Anker’s audio brand, Zolo, launched a Kickstarter campaign for its Liberty+, a pair of graphene-enhanced fully wireless earphones. The Zolo Liberty+ earphones are now available on Amazon.
