Our previous post announced a race around a 100 nm course of six NanoCars, each a unique concept created from only several dozen atoms and powered by electrical pulses. The race was run a few weeks later and two winners declared, due to two different tracks being used. From Swiss news “Swiss team wins shortest… Continue reading USA-Austrian and Swiss Nanocars finish first in first Nanocar race
Six NanoCars, each a unique concept created from only several dozen atoms by one of six teams representing six nations, and powered by electrical pulses, will compete to complete a 100 nm course within 38 hours.
UPDATE 2.0 Dear friends of Foresight, Historically our Update has mainly featured Nanotech News. Now that so many events and announcements are coming thick and fast, we feel like it’s time to update the update — this issue will focus on new events to bring our readers up-to-date, but the next update will probably look… Continue reading October 13 Update
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.
To measure in-plane piezoelectric stress, an MoS2 film was suspended on HSQ posts and clamped by two Au electrodes. When the film was indented with a scanning AFM probe, the induced stress changed the load on the cantilever, which was observed by the deflection of a laser beam. Credit: Berkeley Lab
Calculations using density functional theory have demonstrated that graphene can be made piezoelectric by adsorbing atoms or molecules on one surface, or by adsorbing different atoms or molecules on each surface.
Ultrasound was used to pull on polymer chains attached to opposite sides of a chemically almost inert molecular ring, splitting it into its two components.
Computational work links optically-induced molecular shape change to change in DNA structure to extract useful work.
Arrays of atomic force probe tips are promising nanotech approaches to denser, faster, cheaper memories.
By combining the features of a scanning tunneling microscope (STM) and an atomic force microscope (AFM)–two of the most useful nanotech tools–in a single instrument, IBM scientists have measured the forces necessary to move single cobalt atoms and single carbon monoxide molecules across metal surfaces.
