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.

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.

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.

Improved fuel cell catalyst combines graphene and nanoparticles

First programmable nanowire circuits for nanoprocessors

Researchers at Harvard and MITRE have produced the world’s first programmable nanoprocessor

Improving upon self-assembly

A new technique is reported to use templates to build synthetic molecules the size of proteins by precisely stringing together smaller molecules using an approach based upon the vernier scale.

Molecular machine switches magnetic state at room temperature

Irradiation with two wavelengths of visible light switches the position of a nitrogen atom close to a nickel ion, and in the process switches the magnetic state of the nickel ion.
