Modeling the Electrochemistry of Blood Glucose Test Strips

Stephen Mackintosh
Lifescan Scotland

Lifescan Scotland is a medical device company that designs and manufactures blood glucose monitoring kits for the global diabetes market. These involve the self-monitoring of blood glucose levels through specialized monitoring systems and test strips that comprise of a plastic substrate, two carbon-based electrodes, a thin dry reagent layer, and a capillary volume where the blood is ...

Around the Clock Solar Power

ENEL, Rome, Italy

Italian utility ENEL and the Italian National Agency for New Technologies joined together to develop a new kind of Concentrating Solar Power (CSP), using Parabolic Trough CSP to generate electricity during sunny hours as well as under overcast conditions or at night. This new type of CSP plant depends on molten salt as a medium for storing heat in large, well-insulated tanks. Molten salt has ...

Dielectric Stress Simulation Advances Design of ABB Smart Grid-Ready Tap Changers

Tommi Paananen, David Geibel, Bill Teising, Mårten Almkvist, Jon Brasher, Josh Elder, Bob Elick and Chris Whitten
ABB Alamo

Consumers of power rely on fairly stable voltages. Transformers contain tap changers which vary the ratio of secondary to primary turns by switching the point at which either the input or output circuits are connected. Changing this ratio enables stepped voltage regulation of the output. As the world moves toward the modernized smart grid, the tap changer’s design must be altered to make it ...

Simulation of Magnetic Flux Leakage Inspection

Oliver Nemitz
Salzgitter Mannesmann Forschung, Duisburg, Germany

Salzgitter Mannesmann Forschung (SZMF) advances testing methods for the Salzgitter Group, a leading company that works with the manufacture of, among other things, pipes. In the manufacturing of heavy steel tubing, it is important maintain quality, which is done through conduct non-destructive testing (NDT) using large magnets to identify flaws (magnetic flux leakage inspection). Oliver Nemitz ...

Analysis of Subsea Umbilicals and Cables

Tim Poole, JDR Cables, Cambridgeshire, UK
Mark Yeoman, Continuum Blue, Hengoed, UK

JDR Cables designs-to-spec and manufactures subsea umbilical systems of cables and reelers for the oil and gas and renewable energy industries. In these designs, the harsh environments of deep water pressure, wind and waves, as well as the rough ocean floor must all be considered, along with the forces acting on cables from being pulled and deployed through tight-radius reels. A challenge for ...

Optimizing Ultrasound Piezo-disk Transducers

Lorenzo Spicci & Marco Cati
R&D Department
Esaote S.P.A.
Florence, Italy

Esaote S.p.A. produces medical diagnostic systems, including the manufacturing and sales of ultrasound imaging systems. Lorenzo Spicci and Marco Cati are researching ways to improve ultrasound probes to maximize their performance, knowing a smaller, more effective machine could make this technology more accessible. They used COMSOL Multiphysics to create a model of these transducers, coupling ...

Metamaterials Make Physics Seem Like Magic

Fabio Alves and Gamani
Naval Postgraduate School
Monterey, CA

Metamaterials are manufactured, structured materials that they can interact and manipulate wave phenomena such that objects surrounded by metamaterials are shielded from these waves. In the case of light, metamaterials make these objects ‘invisible’. Researchers throughout the world are applying these materials to many different applications. At NASA Glen Research Center, physicists are ...

Multiphysics Analysis of CO2 Foil Thrust Bearing Characteristics

Treevor Munroe
Knolls Atomic Power Laboratory, Niskayuna, NY

Knolls Atomic Power Laboratory (KAPL) is a research and development facility supporting the United States Naval Nuclear Propulsion Program. KAPL recently collaborated with Bettis Atomic Power Laboratory to test a supercritical carbon dioxide (S-CO2) Brayton power cycle system. The system was designed to operate at high speed and high gas pressure, which means the turbine shaft bearings must ...

Modeling Inertial Focusing in Straight and Curved Microfluidic Channels

J. Martel and M. Toner
Biomems Resource Center
Massachusetts General Hospital

N. Elabbasi, D. Quinn, and J. Bergstrom
Veryst Engineering

In many medical procedures and tests, it is necessary to isolate cells of interest for further analysis. Microfluidics has revolutionized the way in which these tests are conducted enabling, for example, the ability to detect cancer from a blood sample. One of the most promising microfluidic techniques to separate and concentrate cells is called inertial focusing. The equilibrium positions for a ...

The Burning Need for Modeling

Gianluca Argentini
Riello Burners
Legnago, Italy

Riello Burners manufactures high-efficiency low maintenance burners for use in residential and commercial heating applications, as well as in industrial processes. Proper ventilation is crucial for a burner because it maintains appropriate air flow into the combustion head where the flame is located. When designing the fan for any burner, there must be a balance between a configuration which ...
