A new funding opportunity from the Advanced Manufacturing Office, U.S. Department of Energy, incudes a subtopic on Atomically Precise Manufacturing
Longtime Foresight member Dave Forrest is leading DOE’s Advanced Manufacturing Office in advocating atomically precise manufacturing to transform the U.S. manufacturing base.
Computational design of an enzyme that carboligates three one-carbon molecules to form one three-carbon molecule, an activity that does not exist in nature, provides proof-of-principle for a novel metabolic pathway for carbon fixation.
Increasing efficiency and utilization and lowering costs for harvesting, converting, transporting, and storing energy produced from sunlight provides a showcase for a variety of nanoscale materials, structures, and processes.
Highly correlated electron motions resembling electron liquids rather than electron gases, and found in some transition metal oxides, may enable inexpensive substitution for expensive displays.
Eight-armed nanoparticles of gold coated with a gold-palladium alloy proved to be both efficient plasmonic sensors and efficient catalysts, even though gold alone is not normally a good catalyst and palladium is a poor plasmonic material.
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 prototype system to produce chemicals and fuels from sequestered carbon dioxide, water, and sunlight uses semiconductor nanowires to produce electron-hole pairs, which are then used by two types of bacteria to produce oxygen and a variety of useful chemical products.
A nanoporous form of graphene made by burning off other elements from an inexpensive polymer has been used to fabricate flexible supercapacitors via a process that can be scaled to industrial quantities to provide energy storage for wearable, flexible electronics.
A commentary over at Gizmodo argues that ideas about molecular manufacturing that sounded like science fiction in 1986 now sound more like science fact.
Applications of nanotechnology to wearable electronics and other portable devices will benefit from the discovery that adding an insulating layer to a piezoelectric nanostructure increases the output voltage by up to 200 times.
A more general computational framework predicts the structures of 2D and 3D-curved DNA nanostructures impossible to predict using previously available computational methods. May lead to 3D-printing DNA nanostructures?
Painting atomically precise carbon nanotubes onto a cathode produces flat panel lights a hundred times more energy efficient than LEDs.
A phosphorescent molecule is made to flap like a butterfly when absorbed light shortens the distance between two platinum atoms.
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 novel method to control the configuration of atoms in semiconductors grown on graphene will make possible a vast array of new optical devices, including better solar cells.
A recently released technology report titled Nano-solutions for the 21st century outlines nanotech-based solutions to global challenges. Several years in the making, the report was co-authored by Dennis Pamlin, Research Fellow at the Chinese Academy of Social Sciences Research Center for Sustainable Development (RCSD web site currently in Chinese only), and Eric Drexler, Academic Visitor [...]
The Conference to be held February 7-9, 2014 in Palo Alto, California will emphasize the integration of nano-engineered devices and materials into larger, more complex systems.
Covalent bonding of nanocrystals into a glass makes the glass ‘smart’ enough to transmit heat, light, both, or neither as desired.
