Prof. Gerhard Klimeck described the success of nanoHUB.org, a science and engineering gateway providing online simulations through a web browser for nanotechnology research and education.
A molecular robotic arm synthesized from small synthetic organic molecules uses cyclic changes in pH and other reaction conditions to grab and release a cargo molecule, and swing the cargo back and forth between the two ends of the molecular platform.
Each time a laser pulse actuates the cis-trans isomerization of a single carbon-carbon double bond, a single-molecule nanosubmarine made of 244 atoms is driven forward 9 nm against Brownian diffusion.
Single cobalt atoms have been positioned in nitrogen-doped graphene to catalytically produce hydrogen from water almost as effectively as using vastly more expensive platinum catalysts.
A free to read online edition of the classic 3-volume physics text developed from Richard Feynman’s legendary Cal Tech physics lectures, specially designed for online reading, has been made available by the California Institute of Technology and the Feynman Lectures Website.
Optimized Geek podcast featured Christine Peterson on the future of nanotechnology, human lifespan, artificial intelligence, finding love, and other topics.
Dr. Alex Wissner-Gross surveyed the interplay between programmability of bits and atoms in the development of technology, asking how the recent successes with programming bits can help nanotechnology progress in programming atoms.
Simple molecular switches based upon bistable mechanically interlocked molecules can be incorporated within pre-assembled metal organic frameworks and addressed electrochemically.
A review of molecular parts that act as switches, motors, and ratchets illuminates similarities between artificial and biological molecular machines and argues that useful applications are coming.
