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.
A simple DNA scaffold organizes light-collecting molecules for artificial photosynthesis.
Quantum dots are semiconducting, nanoscale clusters that show electronic characteristics distinct from both bulk-scale materials and single molecules. Their special characteristics make quantum dots attractive for a broad range of potential applications, including photovoltaics and nanoscale transistors. The size and shape of quantum dots impact electrical properties and can therefore be used to tune the [...]
Recently we pointed at a Forbe’s interview with Eric Drexler, in anticipation of his pending new book Radical Abundance. The book has shipped, and Drexler’s tour schedule now includes a few stops on the coasts of the U.S: New York: May 6th Los Angeles: May 8th & 9th Seattle: May 9th Find exact times and [...]
In anticipation of Eric Drexler’s new book, Forbes contributor Bruce Dorminey interviews him about the meaning of nanotechnology and its revolutionary prospects. Selected excerpt: … In what fields would APM cause the most pronounced economic disruption and the collapse of global supply chains to more local chains? The digital revolution had far-reaching effects on information [...]
A demonstration that most fundamental biological processes can be implemented in a test tube as efficiently as in live bacteria provides synthetic biology the tools to create a ‘new industrial revolution’, which may or may not lead to more general molecular manufacturing.
Templates made from polymer nanofibers enable the formation of long-lived silicon nanostructures that store ten times as much charge as do graphite battery terminals.
Doping carbon nanotubes with boron while they are being formed produces a novel molecular architecture formed by boron induced kinks and linkages. These nanosponges can be used repeatedly to absorb and retrieve or burn spilled oil.
