DNA Interactions in Crowded Nanopores

K. Misiunas[1], N. Laohakunakorn[1], S. Ghosal[2], O. Otto[1], U. F. Keyser[1]
[1]University of Cambridge, Cambridge, UK
[2]Northwestern University, Evanston, IL, USA

The motion of DNA in crowded environments is a common theme in physics and biology. Examples include gel electrophoresis and the self-interaction of DNA within cells and viral capsids. Here we study the interaction of multiple DNA molecules within a nanopore by tethering the DNA to a ... En savoir plus

Simulation of the Dynamic Behavior of a Droplet on a Structured Surface using the Non-conservative Level Set Method

N. Boufercha, J. Sägebarth, and H. Sandmaier
Universität Stuttgart / IFF-MST, Stuttgart, Germany

The ongoing trend towards miniaturization, higher integration as well as cost efficiency will make it necessary to investigate a new assembly method for micro components. In this paper, a novel method of fluidic-based micro assembly is presented. A self-assembly effect which is caused by ... En savoir plus

Finite Element Analysis of a Bipolar-Electrochemistry Based Water Sensor

J. Castro¹
¹Colorado College, Colorado Springs, CO, USA

This work computationally characterizes a new bipolar electrochemical sensing scheme recently developed for inexpensive detection of heavy metals in water. The sensing scheme employs a two-step optical anodic strip voltammetry protocol that couples a closed bipolar electrochemical cell ... En savoir plus

Simulation on antireflection of the oxide nanosphere monolayer film

李晓红 [1], YUXIAO HOU, HANG LUO, WEI LEI, HONG LEI [1],
[1] 西南科技大学

We theoretically simulate the antireflective effects of oxide nanosphere monolayer films in the visible spectrum. The essential geometric and material parameters of nanosphere films are simulated and different functions are proposed to describe the dependence of reflectance on the ... En savoir plus

Modeling of Random Nanostructures Based on SEM Images and Analysis of Resulting RF-Performance

[2] Institute for Nanostructures and Technology (NST), University of Duisburg-Essen, and CENIDE – Center for Nanointegration Duisburg-Essen, Duisburg, Germany

In the last few years printable electronics has gained a great deal of interest since it promises mechanical flexibility and extremely low production costs. One approach to achieve printable electronic devices relies on the usage of specific inks containing e.g. dispersed semiconductor ... En savoir plus

Designing and Simulating THz Guided Wave Devices Using Finite Element Techniques

L. M. Hayden[1], D. A. Sweigart[1]
[1]Department of Physics, University of Maryland Baltimore County, Baltimore, MD, USA

The generation of terahertz frequency radiation (0.1-10 THz) is an important technological goal due to the use of this non-ionizing radiation to penetrate a wide range of non-conducting materials. One outstanding problem has been the propagation of THz radiation in guided wave devices. ... En savoir plus

Optical Forces and Torques Acting on Non-spherical Metallic Nanoparticles

M. Siler[1], O. Brzobohaty[1], V. Karasek[1], P. Zemanek[1]
[1]Inst. Scientific Instruments of the ASCR, Brno, Czech Republic

Metallic nanoparticles (NPs) are nowadays used in various areas of biology, chemistry or physics. Focused laser beams, optical tweezers, may be used to manipulate such NPs. However, experimental studies showed that there is a discrepancy between their predicted and observed behavior. ... En savoir plus

Study of the Optical Field Scattering Enhancement on a 2D Rough Surface Using COMSOL Multiphysics®

P. de Carvalho Gomes [1], P. Goldberg Oppenheimer [1]
[1]School of Chemical Engineering, University of Birmingham, UK

Surface Enhanced Raman Scattering (SERS) phenomenon is well known for its detection sensitivity, however, to better understand how it works a better insight needs to be developed on the physics behind the phenomenon. The physical aspects known to produce SERS effect are the use of ... En savoir plus

Enhancement of Terahertz Emission by AuGe Nanopatterns

H. Surdi[1], A. Singh[1], S. S. Prabhu [1]
[1]Tata Institute of Fundamental Research, Homi Bhabha  Road, Mumbai,India

Since the advent of Terhertz(THz) technology, improving the THz emission power has been one of the major research goal. One of the methods to increase the THz emission power is to increase the coupling of excitation laser light to the dielectric substrate.The field of nano-plasmonics ... En savoir plus
