Numerical and experimental study of flow and wall mass transfer rates in capillary driven flows in microfluidic channels
TL;DR: The purpose of this work is to analyze the wall mass transfer rates generated by a CD-Flow in a micro-channel and the results have implications in the optimization and design of devices for biological assays.

Resonance-enhanced, rare-gas-assisted femtosecond-laser electronic-excitation tagging in argon/nitrogen mixtures
TL;DR: Multiphoton-resonance enhancement of a rare-gas-assisted nitrogen femtosecond-laser electronic-excitation-tagging (FLEET) signal is demonstrated, producing a stronger and longer-lived FLEET signal following subsequent efficient energy transfer from excited-state argon to the C (3Πu) excited state of nitrogen.

Light-Induced Microfluidic Transport Phenomena
TL;DR: In this article, an experimental setup was constructed using a He-Cd laser (442 nm emission) as the trapping source, and optical trapping experiments were performed under two flow conditions.

Physical explanation of the SLIPI technique by the large scatterer approximation of the RTE
TL;DR: In this paper, the authors compare the performance of the SLIPI technique with a theoretical model that is based on the large scatterer approximation of the Radiative Transfer Equation but modified according to certain constraints.

Particle Image Velocimetry: A Practical Guide
TL;DR: In this paper, the authors present a practical guide for the planning, performance and understanding of experiments employing the PIV technique, which is primarily intended for engineers, scientists and students, who already have some basic knowledge of fluid mechanics and nonintrusive optical measurement techniques.

Digital Particle Image Velocimetry
Christian Willert,Morteza Gharib +1 more
TL;DR: In this article, the directional ambiguity associated with PIV and LSV is resolved by implementing local spatial cross-correlations between two sequential single-exposed particle images, and the recovered velocity data are used to compute the spatial and temporal vorticity distribution and the circulation of the vortex ring.

Determination of displacements using an improved digital correlation method
TL;DR: An improved digital correlation method is presented for obtaining the full-field in-plane deformations of an object by numerically correlating a selected subset from the digitized intensity pattern of the undeformed object.

Fundamentals of digital particle image velocimetry
TL;DR: In this paper, the measurement principle of digital particle image velocimetry (PIV) is described in terms of linear system theory and conditions for PIV correlation analysis as a valid interrogation method are determined.
