Precise matching of STM images and theoretical calculations provides exact lattice locations of dopant atoms, advancing the prospects for silicon-based quantum computers.
Combining computational nanotechnology with a noncontact-atomic force microscope probe tipped by a single CO molecule allowed researchers to visualize the dance of individual chemical bonds during a complex organic reaction on a silver surface.
Chains of monomers joined by non-biological peptoid bonds follow different rules of self-assembly and form structures not found in chains joined by the peptide bonds used to form proteins.
An engineered protein controls the assembly of C60 fullerene molecules into an atomically precise lattice that conducts electricity while neither component alone would.
The claim that the recently reported actuating nanotransducers (ANTS) produce forces “orders of magnitude larger than any produced previously” is challenged by a nanocrystal carbon nanotube device reported 11 years ago.
Atomic resolution measurement of quasi-particle tunneling maps of spin-resolved states reveals interference processes that allow simulation of processes important for developing quantum computers based on atomically precise doping of silicon.
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.
A nanoengine 100 times more powerful than known nanomotors and muscles was demonstrated using the aggregation and dispersal of gold nanoparticles coated with a polymer that undergoes a rapid transition from hydrophobic to hydrophilic.
Christine Peterson will speak on “High-Leverage Altruism” at the fourth annual conference of Effective Altruism, using reason and evidence to improve the world as much as possible, and on nanotechnology at the Singularity University Global Summit, the definitive gathering for those who understand the critical importance of exponential technologies.
Foresight President Julia Bossmann will speak on AI at the TEDxEchoPark “Paradigm Shift” event on Saturday May 14, 2016, in Los Angeles, California.
A DNA strand capable of forming a triple helix with a portion of the DNA double helices in a macroscopic DNA crystal enhances the weak interactions holding the crystal together so that the crystal remains stable in the absence of a high ionic strength environment.
A specially designed triplex forming oligonucleotide bearing a cargo molecule binds to a specific sequence in the major groove of a DNA double helix to form a modified DNA tile that self assembles into a macroscopic crystal in which each helix carries a cargo molecule positioned to sub-nanometer precision.
