A framework to promote critical thinking about nanotechnology

Foresight’s Director of Education Miguel F. Aznar has proposed nine questions to promote critical thinking and contextual understanding of the issues related to nanotechnology to enable the general public and policy makers to make informed choices on subjects influenced by nanotechnology.

Superparamagnetism-explicated-for us

Even though the sound of it is something quite atrocious, superparamagnetism may become a familiar term in the context of nanoscale electronics and devices. Loosely speaking, superparamagnetism is a size-based phenomenon in which materials that are ferromagnetic on the macroscale — meaning predisposed toward strong magnetization at room temperature, such as iron and nickel —… Continue reading Superparamagnetism-explicated-for us

Atomically precise placement of dangling bonds on silicon surface

Nanotechnology researchers in London have used a scanning tunneling microscope to create atomically precise quantum states from dangling bonds on a silicon surface.

RNA-protein motor for unidirectional movement of DNA in nanomachinery

Revolution of DNA around a central channel, rather than rotation, is the method used by a viral molecular motor to package DNA. A structure facilitating bottom-up assembly may lead to roles in nanotechnology for these nanomotors.
