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 ...
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 ...
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 ...
Space-charge-limited flows in the quantum regime
(The American Institute of Physics, 2006-05)
This paper reviews the recent developments of space-charge-limited (SCL) flow or Child-Langmuir (CL) law in the quantum regime. According to the classical CL law for planar diodes, the current density scales as 3/23∕2’s ...
Ultrasound detection using polymer microring optical resonator
(The American Institute of Physics, 2004-11-29)
Application of polymer waveguide microring resonators for high-frequency ultrasound detection is presented. The device consists of a microring optical resonator coupled to a straight optical waveguide which serves as input ...
Biochemical sensors based on polymer microrings with sharp asymmetrical resonance
(The American Institute of Physics, 2003-08-25)
Photonic microresonators have great potential in the application of highly sensitive sensors due to high Q-factor resonances and steep slopes between zero and unity transmission. A microring resonator with increased resonance ...
Nanoscale thermal transport
(The American Institute of Physics, 2003-01-15)
Rapid progress in the synthesis and processing of materials with structure on nanometer length scales has created a demand for greater scientific understanding of thermal transport in nanoscale devices, individual ...
A model of flow and surfactant transport in an oscillatory alveolus partially filled with liquid
(The American Institute of Physics, 2005-03)
The flow and transport in an alveolus are of fundamental importance to partial liquid ventilation, surfactant transport, pulmonary drug administration, cell-cell signaling pathways, and gene therapy. We model the system ...
Magnetically modulated optical nanoprobes
(The American Institute of Physics, 2003-02-17)
We have developed magnetically modulated optical nanoprobes (MagMOONs) to magnetically modulate the signal from fluorescent probes and thus separate it from autofluorescence, electronic offsets, and other background signals. ...
Quantum phase transition and sliding Luttinger liquid in coupled t–J chains
(IOP Publishing Ltd, 2006-05-01)
Using a recently proposed perturbative numerical renormalization-group algorithm, we explore the connection between quantum criticality and the emergence of Luttinger liquid physics in t–J chains coupled by frustrated ...
