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.

Does nanotechnology need PR?

Does nanotechnology need more energetic PR, and if so, what kind?

DNA molecular robots learn to walk in any direction along a branched track

In yet another in a long list of improvements to DNA based molecular machines, DNA molecular robots learn to walk in any direction along a branched track.

Mechanical control of conductance through a single molecule junction

New options to control nanoelectronic systems may arise from the demonstration that mechanical manipulation can control conductance through single molecule electrode junctions.

Time magazine cover article on the Singularity, Ray Kurzweil, AI and nanotechnology

A cover article in Time magazine portrays the Singularity, Ray Kurzweil, AI, life extension, and nanotechnology as “an idea that rewards sober, careful evaluation.”

More on first programmable nanoprocessor

James C. Ellenbogen writes to provide insight and personal perspective on the world’s first programmable nanoprocessor, achieved as the product of a collaboration between Harvard and MITRE, with the team at MITRE comprising Shamik Das, James Klemic, and Ellenbogen.
