Implementation and analysis of polymeric microstructure replication by micro injection molding
(IOP Publishing Ltd, 2004-03-01)
This paper presents the adaptation of a conventional injection molding process to the mass replication of polymeric microstructures with appropriate mold design and process control. Using wet-etched silicon wafers with ...
Controlling Electromagnetic Surface Waves with Scalar and Tensor Impedance Surfaces.
(2013)
The propagation characteristics of electromagnetic waves on various isotropic (scalar) impedance surfaces have been studied for some time, in order to control surface waves and leaky-wave radiation. One and two dimensional ...
Development of a Time-Resolved Laser-Induced Fluorescence Technique for Nonperiodic Oscillations
(2016)
Time-resolved measurements of ion dynamics could be key to understanding the physics of instabilities, electron transport, and erosion in Hall thrusters. Traditional measurements of the ion velocity distribution in Hall ...
Influence of Mn dopants on InAs/GaAs quantum dot electronic states
(The American Institute of Physics, 2011-04-04)
Hydrodynamics and microphase ordering in block copolymers: Are hydrodynamics required for ordered phases with periodicity in more than one dimension?
(The American Institute of Physics, 2004-12-08)
We use Brownian dynamics (BD), molecular dynamics, and dissipative particle dynamics to study the phase behavior of diblock copolymer melts and to determine if hydrodynamics is required in the formation of phases with ...
Electron current extraction from a permanent magnet waveguide plasma cathode
(The American Institute of Physics, 2011-09)
Fundamental Aspects of Episodic Accretion Chemistry Explored with Single-point Models
(IOP Publishing, 2012)
We explore a set of single-point chemical models to study the fundamental chemical aspects of episodic accretion in low-mass embedded protostars. Our goal is twofold: (1) to understand how the repeated heating and cooling ...
Measurement of temperature, fuel concentration and equivalence ratio fields using tracer LIF in IC engine combustion
(Springer-Verlag, 2000-11)
A technique based on planar laser-induced fluorescence of 3-pentanone, for measurements of absolute concentration, temperature and fuel/air equivalence ratios in turbulent, high-pressure combustion systems such as an ...
The Role of Environment in Low-level Active Galactic Nucleus Activity: No Evidence for Cluster Enhancement
(IOP Publishing, 2012)
We use the AMUSE-Virgo and AMUSE-Field surveys for nuclear X-ray emission in early-type galaxies to conduct a controlled comparison of low-level supermassive black hole activity within cluster and field spheroids. While ...
