JoVE Applied Physics
JoVE Applied Physics encompasses a broad range of experimental and instrumental techniques utilized in physics research. Investigations in this area strive to address and answer a broad range of scientific questions, such as device mechanisms and efficiencies, using physical tools. This approach often requires a combination of specialties, and research in this area tends to be interdisciplinary with contributions from mechanical, electrical, and chemical engineers.

Fast Imaging Technique to Study Drop Impact Dynamics of Non-Newtonian Fluids

1Department of Physics, The University of Chicago, 2James Franck Institute, The University of Chicago, 3Department of Mechanical Engineering and Materials Science, Yale University


JoVE 51249

Drop impact of non-Newtonian fluids is a complex process since different physical parameters influence the dynamics over a very short time (less than one tenth of a millisecond). A fast imaging technique is introduced in order to characterize the impact behaviors of different non-Newtonian fluids.

Measurement and Analysis of Atomic Hydrogen and Diatomic Molecular AlO, C2, CN, and TiO Spectra Following Laser-induced Optical Breakdown

1Department of Physics, University of Tennessee Space Institute


JoVE 51250

Time-resolved atomic and diatomic molecular species are measured using LIBS. The spectra are collected at various time delays following the generation of optical breakdown plasma with Nd:YAG laser radiation and are analyzed to infer electron density and temperature.

Time Multiplexing Super Resolving Technique for Imaging from a Moving Platform

1Faculty of Engineering, Bar-Ilan University, 210 Nachum Street, Kfar Saba, Israel


JoVE 51148

A method for overcoming the optical diffraction limit is presented. The method includes a two-step process: optical phase retrieval using iterative Gerchberg-Saxton algorithm, and imaging system shifting followed by repetition of the first step. A synthetically increased lens aperture is generated along the direction of movement, yielding higher imaging resolution.

Measuring Material Microstructure Under Flow Using 1-2 Plane Flow-Small Angle Neutron Scattering

1Center for Neutron Science, Department of Chemical and Biomolecular Engineering, University of Delaware, 2NIST Center for Neutron Research, National Institute of Standards and Technology, 3Institut Laue-Langevin


JoVE 51068

A shear cell is developed for small-angle neutron scattering measurements in the velocity-velocity gradient plane of shear and is used to characterize complex fluids. Spatially resolved measurements in the velocity gradient direction are possible for studying shear-banding materials. Applications include investigations of colloidal dispersions, polymer solutions, and self-assembled structures.

Quasi-light Storage for Optical Data Packets

1Institut für Hochfrequenztechnik, Hochschule für Telekommunikation, Leipzig


JoVE 50468

The article describes a procedure to store optical data packets with an arbitrary modulation, wavelength, and data rate. These packets are the basis of modern telecommunications.

Using Neutron Spin Echo Resolved Grazing Incidence Scattering to Investigate Organic Solar Cell Materials

1Department of Physics and Astronomy, University of Sheffield, 2Department of Chemical and Biological Engineering, The University of Sheffield, 3ISIS Pulsed Neutron and Muon Source Science and Technology Facilities Council, Rutherford Appleton Laboratory


JoVE 51129

Progress has been made in utilizing spin echo resolved grazing incidence scattering (SERGIS) as a neutron scattering technique to probe the length-scales in irregular samples. Crystallites of [6,6]-phenyl-C61-butyric acid methyl ester have been probed using the SERGIS technique and the results confirmed by optical and atomic force microscopy.

Fabrication of Uniform Nanoscale Cavities via Silicon Direct Wafer Bonding

1Department of Physics, The State University of New York at Buffalo, 2Joint Quantum Institute, University of Maryland, 3The National Institute of Standards and Technology, 4Cryogenics and Fluids Branch, NASA Goddard Space Flight Center, 5HRL Laboratories


JoVE 51179

A method for permanently bonding two silicon wafers so as to realize a uniform enclosure is described. This includes wafer preparation, cleaning, RT bonding, and annealing processes. The resulting bonded wafers (cells) have uniformity of enclosure ~1%1,2. The resulting geometry allows for measurements of confined liquids and gasses.

Spatial Separation of Molecular Conformers and Clusters

1Center for Free-Electron Laser Science, CFEL, DESY, 2Department of Physics, University of Hamburg, 3The Hamburg Center for Ultrafast Imaging, University of Hamburg


JoVE 51137

We present a technique that allows the spatial separation of different conformers or clusters present in a molecular beam. An electrostatic deflector is used to separate species by their mass-to-dipole moment ratio, leading to the production of gas-phase ensembles of a single conformer or cluster stoichiometry.

Fabrication and Visualization of Capillary Bridges in Slit Pore Geometry

1Chemical and Biomolecular Engineering Department, Johns Hopkins University


JoVE 51143

A procedure for creating and imaging capillary bridges in slit-pore geometry is presented. The creation of capillary bridges relies on the formation of pillars to provide a directional physical and chemical heterogeneity to pin the fluid. Capillary bridges are formed and manipulated using microstages and visualized using a CCD camera.
