The University of Nottingham is to lead a GBP6.5m research project which aims to make the leap from 2D to 3D in the development of advanced materials and realise the true potential of regenerative medicine and medical devices for the future.
Scientists have caught a glimpse of the elusive toxic form of the Alzheimer's molecule, during its attempt to bore into the outer covering of a cell decoy, using a new method involving laser light and fat-coated silver nanoparticles.
LEGO2NANO aims to bring the world of nanotechnology to school classrooms by initiating projects to develop low-cost scientific instruments such as the Open AFM - an open-source atomic force microscope assembled from cheap, off-the-shelf electronic components, Arduino, Lego and 3D printable parts.
A recent review found some serious shortcomings of the risk assessment process for determining the safety of nanomaterials. The authors argue that these shortcomings are so significant that risk assessment is effectively a naked emperor.
Quantum physics tell us that even massive particles can behave like waves, as if they could be in several places at once. This phenomenon is typically proven in the diffraction of a matter wave at a grating. In a European collaboration, researchers carried this idea to the extreme and observed the delocalization of molecules at the thinnest possible grating, a mask milled into a single layer of atoms.
'Flocking' or 'swarming' behavior is omnipresent in the living world, observed in birds, fish, and even bacteria. Strikingly similar collective action can also be seen in biomolecules within and between cells. New insights into how this action is coordinated at the biomolecular level are emerging from studies of a model system based on actin filaments.
Having generated quite a buzz with their hybrid system of semiconducting nanowires and bacteria that used electrons to synthesize carbon dioxide into acetate, researchers have now developed a hybrid system that produces renewable molecular hydrogen and uses it to synthesize carbon dioxide into methane, the primary constituent of natural gas.
