This cross-sectional transmission electron microscope image shows a sample used for the charge-to-spin conversion experiment. The nano-sized grains of less than 6 nanometers in the sputtered topological insulator layer created new physical properties for the material that changed the behavior of the electrons in the material.

communicate with devices implanted deep within the human body. Image: courtesy of the researchers
Plastic deformation of crystalline materials is
caused by nucleation and multiplication of dislocations under an external force
(A and B). It has been generally believed that brittle inorganic semiconducting
materials have difficulty in formation of dislocations because of their strong
chemical bonds. However, researchers found that a great number of dislocations
are generated and multiplied in ZnS crystals during deformation in darkness
(C), resulting in the extraordinary plasticity that researchers observed. Image courtesy of Atsutomo Nakamura.
TU Wien has developed a sensor for measuring the strength of electric
fields, which is smaller, simpler and less prone to distortion than
comparable devices.Picture: Tiny new sensor - compared to a one-cent-coin
UA Scientists have tracked electrons moving through exotic
materials that may make up the next generation of computing hardware, revealing
intriguing properties not found in conventional, silicon-based semiconductors.
Schematic of the structure and the fabrication process of
Yang's spine-like battery. (a) Schematic illustration of bio-inspired
design, the vertebrae correspond to thick stacks of electrodes and soft
marrow corresponds to unwound part that interconnects all the stacks.
(b) The process to fabricate the spine-like battery, multilayers of
electrodes were first cut into designed shape, then strips extending out
were wound around the backbone to form spine-like structure.
New research led by WMG, at the University of Warwick has found an
effective approach to replacing graphite in the anodes of lithium-ion
batteries using silicon, by reinforcing the anode's structure with
graphene girders. This could more than double the life of rechargeable
lithium-ion based batteries and also increase the capacity delivered by
