Physicist and television host sees future for nanotechnology and AI

In a review of physicist and television host Michio Kaku’s latest book, Foresight advisor Glenn Reynolds finds reason for optimism, but also cause for concern in the career choices of today’s brightest minds.

Mechanical manipulation of silicon dimers on a silicon surface (video)

UK scientists use mechanical force to manipulate silicon dimers on a silicon surface as a first step toward automated atomically precise manufacture of three-dimensional nanostructures.

AFM visualization of molecular robot moving along DNA scaffold (with video)

Researchers in the UK and Japan use atomic force microscopy to visualize a DNA molecular robot moving along a 100-nm DNA track.

Is policy uncertainty the cause of anemic growth in nanotechnology innovation?

Will proposals to establish criteria for green nanotechnology foster growth of nanotechnology innovation?

Controlling the orientation and stretching of DNA attached to a surface

A shear flow processing method has been developed to control the surface attachment and orientation of DNA molecules to use for DNA-organic semiconductor molecular building blocks.

Positional control of chemical reaction a step toward advanced nanotechnology

A step toward advanced nanotechnology has been achieved by using attachment to a surface and confinement by surrounding molecules to make two molecules react to form a product that would not form if they were free to react in solution.

Work theoretically extracted from molecular motor

Computational work links optically-induced molecular shape change to change in DNA structure to extract useful work.

Atomically precise graphene nanotechnology

Sputtering a pattern of zinc atoms on a graphene surface, followed by an acid rinse to remove the zinc, also removes exactly one atomic layer of graphene from where ever the graphene was covered with zinc atoms, forming a pattern on the graphene surface that is atomically precise in the vertical dimension. Resolution in the horizontal dimensions is determined by the mask used to sputter zinc.

Self-assembly of a molecular piston

A French and Chinese collaboration has designed a molecular piston that self-assembles to form a complex stable enough that disassembly is very slow compared to the sliding motion of the piston.

Protein folding is a quantum transition

Chinese scientists demonstrate that protein folding is a quantum transition between torsion states on a polypeptide chain.
