Researchers ave developed a new method to manipulate a wide range of materials and their behavior using only a handful of helium ions. The technique advances the understanding and use of complex oxide materials that boast unusual properties such as superconductivity and colossal magnetoresistance but are notoriously difficult to control.
New research results show that the worst case graphene scenarios roughly match a silicon reference. In the best case scenario, the result is a huge improvement over silicon, with much lower source current and power requirements for a given Hall sensitivity.
The transportation of certain molecules into and out of the cell nucleus takes place via nuclear pores. For some time, detailed research has been conducted into how these pores embedded in the nuclear envelope are structured. Now, for the first time, biochemists have succeeded in elucidating the structure of the transportation channel inside the nuclear pores in high resolution using high-performance electron microscopes.
In a paper that crystalizes knowledge from a variety of experiments and theoretical developments, scientists have demonstrated that the quantum spin Hall effect - an effect known to take place in solid state physics - is also an intrinsic property of light.
Researchers have developed a new ink that can be printed on textiles in a single step to form highly conductive and stretchable connections. This new functional ink will enable electronic apparel such as sportswear and underwear incorporating sensing devices for measuring a range of biological indicators such as heart rate and muscle contraction.
The results of a new study to understand the interactions of various metal alloys at the nanometer and atomic scales are likely to aid advances in methods of preventing the failure of systems critical to public and industrial infrastructure.
Adopting the proximal focused-ion-beam milling technology, researchers developed a three dimensional 4 nanometer wide gap-plasmon antenna. By squeezing the photons into a three dimensional nano space, the researchers were able to increase the intensity of light 400,000 times stronger than that of the incident light.
Moving closer to the possibility of 'materials that compute' and wearing your computer on your sleeve, researchers have designed a responsive hybrid material that is fueled by an oscillatory chemical reaction and can perform computations based on changes in the environment or movement, and potentially even respond to human vital signs.
