Transportation of Nanoscale Cargoes by Myosin Propelled Actin Filaments
Myosin II propelled actin filaments move ten times faster than kinesin driven microtubules and are thus attractive candidates as cargo-transporting shuttles in motor driven lab-on-a-chip devices. In addition, actomyosin-based transportation of nanoparticles is useful in various fundamental studies. However, it is poorly understood how actomyosin function is affected by different number of nanos...
متن کاملNanoscale self - affine surface smoothing by ion bombardment
Topography of silicon surfaces irradiated by a 2 MeV Si + ion beam at normal incidence and ion fluences in the range 10 15 − 10 16 ions/cm 2 has been investigated using scanning tunneling microscopy. At length scales below ∼ 50 nm, surface smoothing is observed; the smoothing is more prominent at smaller length scales. The smoothed surface is self-affine with a scaling exponent α = 0.53 ± 0.02....
متن کاملSelf - propelled particles driven by light
In dieser Arbeit untersuche ich die wesentlichen Eigen-schaften biologischer und künstlicher aktiver Systeme undstelle eine neue Technik zur Herstellung von selbstgetriebe-nen mikroskopischen Kolloiden vor. Um den Antrieb zuerhalten nutzen wir phoretische Kräfte, welche ins Spielkommen, wenn ein Janus-Teilchen seine Umgebung asym-metrisch verändert. Erheblicher experimen...
متن کاملSelf-cleaning of superhydrophobic surfaces by self-propelled jumping condensate.
The self-cleaning function of superhydrophobic surfaces is conventionally attributed to the removal of contaminating particles by impacting or rolling water droplets, which implies the action of external forces such as gravity. Here, we demonstrate a unique self-cleaning mechanism whereby the contaminated superhydrophobic surface is exposed to condensing water vapor, and the contaminants are au...
متن کاملSelf-propelled Leidenfrost droplets.
We report that liquids perform self-propelled motion when they are placed in contact with hot surfaces with asymmetric (ratchetlike) topology. The pumping effect is observed when the liquid is in the Leidenfrost regime (the film-boiling regime), for many liquids and over a wide temperature range. We propose that liquid motion is driven by a viscous force exerted by vapor flow between the solid ...
