Researchers have shed new light on a particular class of active matter called active colloids - collections of tiny moving particles suspended in fluid. Using numerical models and computer simulations, the researchers show how spinning particles, pushed about by the fluid flows created as each particle spins, can arrange themselves into an array of emergent macro-scale patterns.
A method for making elastic high-capacity batteries from wood pulp was unveiled by researchers. Using nanocellulose broken down from tree fibres they produced an elastic, foam-like battery material that can withstand shock and stress.
Researchers have successfully produced graphene nanoribbons by making use of the phenomenon that inorganic nanomaterials self-assemble into regular structures on graphene. This will enlarge the possible applications of graphene, which is expected to be an important alternative material to silicon for semiconductor devices.
A research team has developed a new approach for more realistic computer models of battery electrodes. They combined images from synchrotron tomography that capture three-dimensional structure at micron resolution with those from an electron microscope that can even resolve nanometre-scale features over a small section.
Researchers have eliminated problematic pinholes in the top layer of next-generation solar cells in development. At the same time, they have significantly improved the lifetime of the solar cell and made it thinner.
