Magnetic cooling is a promising new refrigeration technology boasting several advantages – ranging from lower energy consumption to eliminating the use of hazardous fluids – that combine to make it a much more environmentally friendly option than today’s standard fluid-compression form of refrigeration.
AMBER, the Science Foundation Ireland-funded materials science institute headquartered at Trinity College in Dublin today announced a new strategic partnership with Bell Labs, the research arm of Alcatel-Lucent (Euronext Paris and NYSE: ALU). AMBER which is funded by the Department of Jobs in Ireland through Science Foundation Ireland, and Bell Labs will embark on joint energy research projects in the fields of energy harvesting, energy efficiency and energy storage.
In industrialized countries, corrosion guzzles up to 4 percent of economic performance annually. Substances that protect metals effectively from its ravages are often damaging to the environment or have other disadvantages. Consequently, scientists working with Martin Stratmann and Michael Rohwerderat the Max-Planck-Institut für Eisenforschung (Iron Research) in Düsseldorf are developing synthetic coatings that can protect steels and other metals from rust and heal themselves if they become damaged.
Controlling the flow of heat through materials is important for many technologies. While materials with high and low thermal conductivities are available, materials with variable and reversible thermal conductivities are rare, and other than high pressure experiments, only small reversible modulations in thermal conductivities have been reported.
In addition, the term 'engineering plastic' covers materials that have superior properties which were not particularly available in conventional polymeric materials such as the exceptionally high heat resistance of polyimides and polysulfides. In addition to conventional materials engineering polymers include materials as diverse as polyether ether ketone, polyimide, polyetherimide and polysulfides and polysulfides.
Shape-memory polymers (SMP) are a unique branch of the smart materials family which are capable of changing shape on-demand upon exposure to external stimulus. The discovery of SMP made a significant breakthrough in the developments of novel smart materials for a variety of engineering applications, superseded the traditional materials, and also influenced the current methods of product designing.
The aqueous-based lithium-ion battery has the potential to eliminate the risks associated with state of the art lithium-ion batteries, where the organic solvents are highly flammable.
BYU research on super-hydrophobic surfaces could result in cleaner, more efficient power
Lubricants are required wherever moving parts come together. They prevent direct contact between solid elements and ensure that gears, bearings, and valves work as smoothly as possible. Depending on the application, the ideal lubricant must meet conflicting requirements. On the one hand, it should be as thin as possible because this reduces friction.
Scientists from IBM Research have successfully discovered a new class of polymer materials that can potentially transform manufacturing and fabrication in the fields of transportation, aerospace, and microelectronics.
