Exotic Material Boosts Electromagnetism Safely 
Using exotic man-made materials, scientists from Duke University and Boston College believe they can greatly enhance the forces of electromagnetism (EM), one of the four fundamental forces of nature, without harming living beings or damaging electrical equipment.

This theoretical finding could have broad implications for such applications as magnetic levitation trains, which ride inches above the tracks without touching and are propelled by electro-magnets.

As the term indicates, EM is made up of two types of fields – electric and magnetic. Alternating current sources generate both electric and magnetic fields, and increasing one of them generally leads to the increase in the other. But electrical fields can cause problems if they get too high.

"For any EM applications dealing with things on the human scale, high-intensity EM fields needed for the generation of strong forces interfere with other devices and may be harmful to biological tissues, including humans," said Yaroslav Urzhumov, an assistant research professor in electrical and computer engineering at Duke's Pratt School of Engineering. 

"The severity of this problem is substantially reduced if the fields are predominantly magnetic, since virtually all biological substances and the majority of conventional materials are transparent to magnetic fields," Urzhumov said. "While we can't suppress the electric field completely, a magnetically-active metamaterial could theoretically reduce the amount of current needed to generate a high enough magnetic field, thus reducing parasitic electric fields in the environment and making high-power EM systems safer."

The solution to this problem comes from the recent ability to fabricate exotic composite materials known as metamaterials, which are not so much a single substance, but an entire man-made structure that can be engineered to exhibit properties not readily found in nature. These metamaterials can be fabricated into a limitless array of sizes, shapes and properties depending on their intended use.

In the magnetic levitation train example, conventional electromagnets could be supplemented by a metamaterial, which would have been designed to produce significantly higher intensities of magnetic fields using the same amount of electricity.

The Duke scientists came up with the theoretical underpinning for the metamaterial, which is being fabricated by collaborators at Boston College, led by Willie Padilla, associate professor of physics.

"The metamaterial should be able to increase the magnetic force without increasing the electric current in the source coil," Urzhumov said. "The phenomenon of magnetostatic surface resonance could allow magnetic levitation systems to increase the mass of objects being levitated by one order of magnitude while using the same amount of electricity."
EM is currently being used in a host of devices and applications, ranging from subatomic "optical tweezers" scientists use to manipulate microscopic particles with laser beams, to potentially highly destructive weapons.

Urzhumov works in the laboratory of Duke's David R. Smith, William Bevan Professor of electrical and computer engineering and director of Duke's Center for Metamaterials and Integrated Plasmonics. Smith has previously demonstrated that similarly designed metamaterials could act as a "cloak" to different frequencies of light and other waves.

Wenchen Chen and Chris Bingham from Boston College's physics department were also members of the research team.

lakeshoreLake Shore Cryotronics Introduces 8400 Series Hall Effect Measurement System
Lake Shore Cryotronics, Inc. has introduced the new 8400 Series Hall effect measurement system (HMS), developed in collaboration with Toyo Corp. of Japan. The 8400 Series HMS features optional AC field measurement capability that enables measurement of Hall mobilities down to 0.001 cm2/V s – lower than ever possible using traditional DC field Hall measurement techniques. Measurement of low mobilities is highly desirable for contemporary semiconductor and electronic materials being developed for such applications as solar cells, thermoelectric materials, and organic electronics.

The Model 8404 HMS provides a robust platform to which new features can be added as material measurement needs evolve. The standard system comes equipped with DC field measurement capabilities and a resistance range from 0.5 mΩ to 10 MΩ. The Model 8404 HMS can provide a full range of Hall measurements on van der Pauw samples. An assortment of options, including AC field capability, variable temperature assemblies (15 K to 1273 K), high resistance (up to 200 G), and low resistance (to 10 µ) broaden measurement opportunities and simplify experimental processes.

In the past, the traditional DC field Hall measurement technique has been sufficient to measure materials with mobilities down to approximately 1 cm2/V s. However, the emerging class of photovoltaic (solar cell), thermoelectric and organic electronic materials is characterized by low mobilities that are difficult, if not impossible to measure. The 8400 series HMS uses AC field techniques to extract the diminishingly small Hall voltage from the background noise produced by these new materials, and closes the gap between traditional DC field measurement techniques and these low mobility materials.

Spacemag Scheduled for Launch
Spacemag, Bartington Instruments’ first magnetometer for use in space, is to be carried in a satellite designed by the Instituto Universitario de Microgravedad ‘Ignacio Da Riva’ of Spain’s Universidad Politécnica de Madrid (IDR/UPM).


The satellite, UPMSAT-2, is being manufactured and assembled by IDR/UPM and will be launched into a low earth polar orbit by the end of the first quarter of 2013. Spacemag will be fitted to the satellite and will collect in-flight magnetic field information.


Spacemag is a three-axis fluxgate magnetometer designed for use in spacecraft attitude control systems. Lightweight, low noise and with minimal heat output, it has been shock and vibration tested to NASA-STD-7001, and its vacuum compatible components are specified for 100 kRad.


The sensor was tested at RAL Space (Rutherford Appleton Laboratories) to verify its functionality for long term use in a space environment.

Infolytica Releases Motorsolve V3.0 with Thermal Analysis Module
Infolytica Corp. has released its MotorSolve v3. The new MotorSolve Thermal module is included with this latest version, giving motor designers a complete software tool, which they can use to thoroughly evaluate the impact of temperature and different cooling methods on the performance of brushless, PMAC and induction machines.

MotorSolve Thermal is a 3D automated-FEA analysis module that enhances the accuracy of MotorSolve’s existing electromagnetic result computations by accounting for heating and cooling on performance as well as offering new temperature related outputs. It accounts for conduction, radiation and natural/forced convection heating or cooling.
The MotorSolve user interface has been updated to include a full 3D view of the housing and the machine, giving a real time view of the design. The use of descriptive names and annotations on the model remove any guesswork as to the nature and impact of each parameter.

This latest release is unlike other design software solutions, as it eliminates the need to create two separate machine models for thermal and electromagnetic analysis. Within just one design environment, you can perform both types of analysis. There is no template matching or software linking. Just specify the motor and housing geometry, winding details, losses, materials and cooling type once in order to:

  • Calculate temperatures using the losses from the magnetic analysis
  • Perform the magnetic analyses taking into account the change in material properties due to the change in temperatures

MotorSolve Thermal offers both steady state and duty cycle experimental condition. The extensive list of performance charts includes duty cycle losses, average or min/max temperatures and heat flux.

Biotech Firm Spun Off from Children's Hospital Raises $7 Million to Advance Magnetic-Based Vascular Treatment
Vascular Magnetics, the first start-up company spun off by The Children's Hospital of Philadelphia, has raised $7 million to advance development of an innovative drug delivery system using magnetically targeted nanoparticles to treat peripheral artery disease.

Vascular Magnetics, based in West Philadelphia, announced that Devon Park Bioventures, of Wayne, Pa., is the sole investor in this Series A financing agreement.

"It's exciting to see that one of our hospital's research discoveries has attracted investors to move it toward commercial development," said Philip R. Johnson, M.D., chief scientific officer and executive vice president, The Children's Hospital of Philadelphia. "This work can have multiple benefits—directly to patients receiving a new treatment, and also to children whose lives will be improved by future research supported by revenue generated by this technology."

Vascular Magnetics was co-founded in 2010 by Robert J. Levy, M.D., William Rashkind Endowed Chair of Pediatric Cardiology at The Children's Hospital of Philadelphia, and Richard S. Woodward, Ph.D. Levy, whose extensive laboratory research forms the basis of the proprietary drug delivery system, is the firm's founding scientist. Woodward, who has a business background in nanotechnology and polymeric coatings, is the company's president and chief operating officer.

The drug delivery system at the heart of the company's work is called vascular magnetic intervention. The system combines biodegradable, magnetic drug-loaded particles with a magnetic targeting catheter and a device that creates a uniform magnetic field. The system, which Levy has tested in animals, guides the particles to the walls of arteries narrowed by peripheral artery disease. At the disease site, the particles remain in place, slowly biodegrading and releasing the drug paclitaxel, which prevents re-obstruction of the artery.

The technology could fill an important unmet need in treating peripheral artery disease (PAD), in which blocked arteries, primarily in the legs, exact a heavy toll in some 30 million older adults in North America and Europe. Diabetes patients and smokers are particularly affected by this painful, debilitating condition, responsible for the majority of amputations performed in this country. Drug-eluting stents, currently used in heart disease, are less effective in PAD. Levy said that magnetic intervention could deliver more effective doses of drugs than the standard drug-eluting stents, and could be used to re-administer drugs as needed.

As a new platform technology, Levy added, vascular magnetic intervention could also be adapted to delivering other agents, such as therapeutic genes or cells, and has potential utility in treating heart conditions in children. In the near future, Vascular Magnetics will complete preclinical development of its technology, with plans to begin its first clinical trial in 2014, in adult patients.

Great Western Minerals Group’s LCM Receives Rare Earth Metal Making Environmental Permit
Great Western Minerals Group Ltd.’s (GWMG) wholly owned subsidiary Less Common Metals (LCM), located in Birkenhead, U.K., has been granted its environmental permit to carry out electrolytic production of rare earth metals at LCM's new Hooton Park location.

The permit, issued by the United Kingdom Environment Agency, enables LCM to produce rare earth metals in accordance with the highest of national environmental, health and safety standards.

Ian Higgins, Managing Director, Metals and Alloys at LCM said, "The detailed design and production of the first two metal making cells, which have now been received by LCM, was carried out by a leading United Kingdom-based foundry technology company. The initial trials of the metal making system are scheduled to commence in May 2012. Our plan is to have six cells in full operation by the end of 2012 at a level of production that will fully supply the requirements for LCM's recently commissioned strip casting furnace."

Jim Engdahl, president and CEO of GWMG said, "The process of fused salt electrolysis of rare earth oxides to metals increases the existing metal and alloy making capability at LCM into bulk production of metals, principally for the permanent magnet alloy business. This represents one more step toward GWMG being the most fully integrated rare earth company in the world. That, in turn, translates into additional self-sufficiency for our production cycle and certainty of supply for GWMG’s global customers."

roskillRare Earths & Yttrium: Market Outlook to 2015, 14th Edition 2011
The rare earths industry is at a turning point, as new sources of supply come on stream, industry in China consolidates under a limited number of state owned enterprises, and consumers re-evaluate the way in which rare earths are used after a period of unprecedented high prices.

Measures taken to control production in China are becoming more effective, resulting in a decline in official production of more than 4%py from 2006 to 2011. In 2011, China accounted for 94 percent of world production and this is expected to fall to just over 70 percent by 2015. An increasing proportion of Chinese supply is now required for its domestic industries which will account for 70 percent of total demand for rare earths in 2011. New projects in the rest of the world are forecast to contribute an additional 56,000 to 57,000t REO to supply by 2015.

All the growth in demand between 2005 and 2010 came from China (11%py); growth in the rest of the world fell by almost 4%py, largely a consequence of the global economic downturn in 2009 and a tightening of the Chinese export quota in 2010, which restricted availability. In the years to 2015, the main demand driver will be the use of rare earths in NdFeB magnets, which are forecast to grow at 11-13%py as potential markets expand to include applications in permanent magnet motors for electric vehicles and wind turbines. Magnets could account for nearly one third of demand by 2015. Strong growth in demand is also forecast for rare earths in NiMH batteries, phosphors, optical glass and ceramics.

From June 2010, when the Chinese export quota fell by nearly 40 percent, prices for most rare earths began to rise sharply, particularly for the lower cost LREEs where traders limited sales in order to maximize exports of higher value HREEs. Prices for those rare earths used in magnet alloys also rose rapidly in response to strong demand within China. At the start of Q4 2011, prices underwent some correction but are still at a level that has caused end users to look at reformulation, alternative technologies and recycling.
