A 100-Fold Improvement in Lithography Resolution Realized with a 150-Year-Old “Perfect Imaging” System

Juan Carlos Miñano and Dejan Grabovičkić
Cedint Polytechnic University of Madrid

The idea of "perfect imaging", that is a resolution less than the wavelength of light producing the image, was first proposed in the mid-19th century by famed Scottish physicist James Clerk Maxwell. For the next 150 years, it was widely believed that such was impossible due to the fact that light diffracts around points that are the same size or smaller in wavelength. Then, in 2009, Ulf ...

Simulation-Based Design of New Implantable Hearing Device

Patrik Kennes
Cochlear Technology Centre, Mechelen, Belgium

Cochlear Technology Centre Europe (CTCE) develops new technology for hearing implants. Their current work is with a new type of hearing implant, a Direct Acoustic Cochlear Implant called CodacsTM. This product imposes structural, pressure waves directly to the cochlea, stimulating it this way, as opposed to amplifying sound. Using COMSOL Multiphysics, the team was able to test the many ...

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 ...

Sea Floor Energy Harvesting

Nagi Elabbasi, Brentan Alexander, and Stuart Brown

Veryst Engineering, Needham, MA, USA

Veryst Engineering has provided design solutions for a variety of industries in the field of energy harvesting. One of their current projects is working on ocean floor sensors, used in naval applications, environmental monitoring, earthquake monitoring, and oil exploration, which presently run on battery-power requiring expensive battery replacement or recharging. Veryst is developing a ...

Analysis and Simulation of Rock Properties

VSG, Burlington, MA, USA

VSG provides high-performance 3D visualization toolkits and software for a number of industries, including materials science and geosciences. One application of their technology is with American oil and gas reserves. The difficulty of accessing these sites has forced the industry to turn to the technique of injecting fluid under pressure into rock deposits. This technique requires knowledge of ...

Modeling Scar Effects in Electrical Spinal Cord Stimulation

Kris Carlson, Dr. Jay Shils & Dr. Jeffrey Arle
Lahey Clinic
Burlington, MA

The Neuromodulation Group at Lahey Clinic conducted a study based upon spinal cord stimulation (SCS). SCS involves implanting a series of electrodes that apply electric potential to the spine, interfering with pain signaling circuitry. It’s used to alleviate chronic back and leg pain. Although the treatment remains effective for years, the electrodes must be reprogrammed through trial and ...

Cluster Simulation of Refrigeration Systems

Stephen Codyer & Mehdi Raessi
Department of Mechanical Engineering
UMass Dartmouth
Dartmouth, MA

Jessica Currie & Vladimir GoldsteinSunwell Technologies, Inc., Woodbridge
ON, Canada

Sunwell Technologies Inc. produces and distributes the slurry ice (Deepchill™) that is an environmentally-friendly way to refrigerate foods and other items in trucks and the like. They commissioned the Computational Multiphase Flows group at the University of Massachusetts, Dartmouth (UMass Dartmouth) to provide simulation support to the experimental investigations performed by Sunwell. Known ...

Shape Changing Lubricants

Robert Ian Taylor
Shell Global Solutions
Cheshire, UK

Shell Global Solutions UK is conducting research to optimize lubricants for the fuel economy. A problem exists in creating a balance between energy efficient lubricants that decrease friction, and the higher wear created by the thinner oil film in the lower friction lubricant. There are also many points of contact with extremely high pressure, which increases the viscosity of the lubricant, ...

Multiphysics Simulations Help Track Underground Fluid Movements

A. Haas, H. Mahardika, M. Karaoulis, and A. Revil
Colorado School of Mines, USA

Combining acoustic and electromagnetic analyses helps scientists to more efficiently measure and survey subterranean regions. Acoustic waves can travel long distances, but have limitations when it comes to providing details about formation properties, and cannot be used to identify the liquids flowing through them. Electromagnetic waves do not propagate as far as acoustic waves, but can identify ...

How Reclosers Ensure a Steady Supply of Power: It’s All in the Magnet

O. Craciun, and colleagues
Ladenburgh, Germany

When a tree branch touches overhead cables and causes a momentary short circuit, your lights may flicker. A device called a recloser ensures that power to your home is not cut off for a longer period. ABB AG, a leading manufacturer in power technology, is working towards designing a more reliable recloser. One objective in this design process was to optimize the size of the permanent magnet ...
