Charge fluctuations in nanoscale capacitors.
The fluctuations of the charge on an electrode contain information on the microscopic correlations within the adjacent fluid and their effect on the electronic properties of the interface. We investigate these fluctuations using molecular dynamics simulations in a constant-potential ensemble with histogram reweighting techniques. This approach offers, in particular, an efficient, accurate, and ...
متن کاملMinimum size limit for useful locomotion by free-swimming microbes.
Formulas are derived for the effect of size on a free-swimming microbe's ability to follow chemical, light, or temperature stimuli or to disperse in random directions. The four main assumptions are as follows: (i) the organisms can be modeled as spheres, (ii) the power available to the organism for swimming is proportional to its volume, (iii) the noise in measuring a signal limits determinatio...
متن کاملSimultaneous Nanoscale Surface Charge and Topographical Mapping.
Nanopipettes are playing an increasingly prominent role in nanoscience, for sizing, sequencing, delivery, detection, and mapping interfacial properties. Herein, the question of how to best resolve topography and surface charge effects when using a nanopipette as a probe for mapping in scanning ion conductance microscopy (SICM) is addressed. It is shown that, when a bias modulated (BM) SICM sche...
متن کاملMineralogy and Cation Exchange Properties of Libby Vermiculite Separates as Affected by Particle-size Reduction*
-A vermiculite (Libby, Montana) sample obtained from the Zonolite company contained mostly coarse-grained separates with only 8.7 per cent clay. The 2-50 #m fraction was used for particle-size reduction studies by wet and dry grinding, and size-fractionated into < 2, 2-5, 5-20 and 20--50 #m sizes. About 18 per cent of the sample was attrited to clay after 64 hr of wet grinding, but as much as 5...
متن کاملCornell NanoScale Science & Technology Facility
Electronic generation of THz signals using GaN is predicted to exhibit high efficiency. Theory shows that electrons can be ballistically accelerated to the Brillouin zone energy limit of 2.7 V [1,2], and above 1.0 V, they will pass beyond the inflection point and have negative effective mass. Experiments by M. Wraback [3] indicate the presence of negative differential resistance (NDR). Finite e...
