This dilemma is for screening if you are a human visitor and to avoid automatic spam submissions.
Dynamics of initiation, termination and reinitiation of DNA translocation because of the motor protein EcoR124I
Our work was rapidly followed up by Other folks, most notably by Phaedon Avouris and colleagues at IBM, who in Oct 1998 revealed their results on transistors made out of solitary- and multi-walled carbon nanotubes in Utilized Physics Letters.
This yielded a breakthrough. Inside of only some months, we have been capable to evaluate transport by means of somebody solitary-walled carbon nanotube. Based upon reduced-temperature experiments by an excellent PhD college student in my group, Sander Tans (now a valued colleague and professor at Delft University of Technology by having an active investigate lab at AMOLF in Amsterdam), we showed that carbon nanotubes were real quantum wires with very very long (micrometres) electronic coherence lengths — confirming theoretical predictions of metallic conduct.
Electrical transportation in monolayers of phthalocyanine molecular wires and AFM imaging of an individual wire bridging two electrodes
What distinguishes biology from chemistry is these factors with each other make up a dwelling program. The trick of mentioned everyday living, I believe, lies during the interactions, the interplay of All those molecules. The large dilemma in regards to the origin of life continues to be unanswered. How did we at any time evolve from easy molecules ceesdekker.net in the extremely intricate systems we see right now? We do not know. I want to work on these kinds of huge, open up questions.’
Circulation-pushed rotary motors which include windmills and water wheels drive practical processes in human Culture. While samples of such rotary motors also function prominently in cell biology, their synthetic building with the nanoscale has remained challenging. Here we show movement-driven rotary motion of a self-organized DNA nanostructure which is docked onto a nanopore in a thin sound-condition membrane. An elastic DNA bundle self-assembles into a chiral conformation upon phoretic docking onto the strong-state nanopore, and subsequently displays a sustained unidirectional rotary movement of up to twenty rev s−one.
‘You should not just consider the concerns of tomorrow, but additionally think about the concerns from the day following tomorrow’
1). The existing–voltage curves showed major modulations with gate voltage, even at space temperature, which was in keeping with band bending inside a ~0.six eV bandgap semiconducting nanotube. These information also confirmed that the conductance may be modulated by 6 orders of magnitude by modifying the gate voltage. The effects of this get the job done — a room-temperature transistor made out of a single carbon nanotube molecule — have been posted in Nature in May perhaps 1998.

Dekker heeft fundamentele ontdekkingen gedaan op het gebied van koolstof nanobuisjes. Mede vanwege deze werkzaamheden is hij al jaren de meest geciteerde fysicus in Nederland. Tegenwoordig onderzoekt hij satisfied enkel-molecuultechnieken de biofysica van moleculen in de biologische cel. Dekker is naast zijn wetenschappelijk werk ook bekend vanwege zijn belangstelling voor de relatie tussen geloof en wetenschap en de discussie rond clever design and style in 2005. (nl)
