Simulation of the Flow of an Autonomous Spherical Ball inside a Pipeline

W. Chalgham [1], A. C. Seibi [1], M. Mokhtari [1],
[1] University of Louisiana at Lafayette, Lafayette, LA, USA

One of the limitations of pipelines performance and structural integrity assessment is the continuous inspection of possible leaks due to corrosion or other types of failure mechanisms. Efforts to develop new technologies started several decades ago where different inspection techniques ... En savoir plus

Expanding Your Materials Horizons

R. Pryor[1]
[1]Pryor Knowledge Systems, Inc. (COMSOL Certified Consultant), Bloomfield Hills, Michigan, USA

Materials and their related properties are intrinsically fundamental to the creation, development and solution of viable exploratory models when using numerical analysis software. In many cases, simply determining the location, availability and relative accuracy of the necessary material ... En savoir plus

Design and Characterization of a Small Volume Reactor for the High Pressure Invacuo Study of Catalytic Surface Reactions

[2]Naval Surface Warfare Center, Corona, CA, USA
[3]Naval Surface Warfare Center, Crane, IN, USA
[4]Department of Chemistry, University of California, Riverside, CA, USA

The design and construction of ultra-high vacuum (UHV) systems for the study of surface reactions has lead to high impact innovation in a myriad of industries. A small volume reactor compatible with ultrahigh vacuum (UHV) surface-science instrumentation has been designed, modeled and ... En savoir plus

Simulations of Scanning Electrochemical Microscopy Experiments in Pure Negative and Positive Feedback Mode with Ring Microelectrodes

J. Mauzeroll[1], M. Mayoral[1], and D. Fabre[1]
[1]Department of Chemistry, Université du Québec à Montréal, Montreal, Quebec, Canada

Scanning electrochemical microscopy (SECM) is a powerful tool recently developed for studying structures and processes in micrometer and submicrometer sized systems. It can probe electron, ion, and molecule transfers, and other reactions at solid-liquid, and liquid-liquid, interfaces . ... En savoir plus

Optimization of the Supersonic Gas Jets' Parameters for In-Gas-Jet Nuclear Spectroscopy Studies

A. Zadvornaya [1], Y. Kudryavtsev [1],
[1] KU Leuven, Leuven, Belgium

The in-gas-jet laser ionization and spectroscopy method (Figure 1) that has been developed at KU Leuven allows to produce and to perform laser spectroscopy of short-lived radioactive isotopes created in different types of nuclear reactions [1,2]. To realize the advantages of in-gas-jet ... En savoir plus

Vertically Emitting Microdisk Lasers

L. Mahler, A. Tredicucci, and F. Beltram
NEST-INFM and Scuola Normale Superiore, Pisa, Italy

We describe the modeling of microdisk lasers displaying vertical emission. The devices are THz quantum cascade lasers with metallic gratings fabricated along the circumference. The emission properties of the fabricated devices are well explained by the model, good mode control is ... En savoir plus

Modeling and Simulation of Redox Titration of Metal Oxides at Porous Microelectrodes

L. Balboa [1], M. Hänsch [1] , J. Behnken [1], G. Wittstock [1],
[1] Institute of Chemistry, Carl von Ossietzky University of Oldenburg, Oldenburg, Germany

In the past two decades, highly porous nanostructured materials have been investigated and used for a large variety of applications, such as catalysis, energy conversion/storage, optics, sensing and more. Nanoporous gold (npAu) is one of such materials which have shown great potential as ... En savoir plus

Design of a MEMS Bolometer with Absorptive Element as Piezo-Protein

H. Sinha [1], A. Mukherjee[1], N. Chattoraj[1],
[1]Birla Institute of Technology Mesra, Ranchi, Jharkhand, India

Bolometer is a thermal infrared sensor used for measuring the intensity of radiation via the heating of a material due to the radiations. A bolometer consists of an absorptive element, a thin layered material, connected to a thermal reservoir. The result is that any radiation received on ... En savoir plus

Generation of Divergence-Free Bessel-Gauss Beam from an Axicon Doublet for km-Long Collimated Laser

C. Daengngam [1], S. Boonsit [1], P. Kalasuwan [1], P. van Dommelen [1], P. Srisamran [1],
[1] Department of Physics, Faculty of Science, Prince of Songkla University, Songkhla, Thailand

A well-collimated intensity profile at long distance has long been a desired laser property crucial for many potential applications. Extending a non-diverging range for ordinary laser beyond kilometers scale would permit superior performance for optical technologies, including LIDAR, or ... En savoir plus

Extended Physics Modeling of the Resin Flow During Vacuum Infusion Processes
