Notes for 400 hours of Richard Feynman’s Hughes Lectures

While a consultant for Hughes Aircraft Company from 1966 through 1971, Richard Feynman delivered about two hundred lectures that were available only to Hughes employees. Unfortunately these lectures were never recorded. An attendee has now released 1000 pages of notes he took and transcribed from these lectures.

Using DNA nanotechnology to cast arbitrarily shaped nanoparticles

Metal or other inorganic nanoparticles of 20 to 30-nm scale can be cast in arbitrary 3D shapes and configurations dictated by stiff, atomically precise molds constructed using scaffold DNA origami.

Grant program to support nanotechnology and other infrastructure

The US National Science Foundation announced a new grant program to develop and apply next-generation networking to advance nanotechnology and other emerging technologies to meet important national needs.

Light-driven molecular flapping emits white light

A phosphorescent molecule is made to flap like a butterfly when absorbed light shortens the distance between two platinum atoms.

Foresight Directed/Programmable Matter for Energy Workshop

A small, interactive group of invited experts gathered in Palo Alto recently to discuss prospects for revolutionary advances in energy storage, transmission, and generation through nanotechnology.

A Breakthrough in 3D Imaging by EM Alone

The need for improved imaging and characterization on the nanoscale was emphasized in the 2007 Roadmap and again at the 2013 Foresight Conference on Atomic Precision. We noted last year a new advancement in atomic-scale resolution of 10-nm platinum particles, requiring multiple imaging techniques in combination, and recently the marked improvement in optical imaging for… Continue reading A Breakthrough in 3D Imaging by EM Alone

Tailoring the shapes of organic molecules by assembly-line synthesis

To emulate the process by which nature assembles complex organic molecules by passing subunits through a series of enzyme domains, UK chemists developed a procedure to elongate a boronic ester by using a reagent that inserts into carbon-boron bonds with precise control of molecular configuration.

Nanomanufacturing grants available from US National Science Foundation

The US NSF has announced a program to support fundamental research leading to complex nanosystems.

DNA nanotechnology and the atoms to micrometer nanofabrication gap

A new DARPA program seeks to bridge the gap from atoms to macroscale product manufacture in two steps, the first of which is from atoms to micrometer-scale feedstocks. DNA origami may be part of the solution.

Scaffolded DNA origami improvements advance DNA nanotechnology

A 10-fold larger breadboard and 350-fold lower DNA synthesis costs make DNA origami a more useful stepping-stone toward atomically precise manufacturing.
