MAP provides algorithms for use in the modelling of materials. It features general information about MAP, a library of downloadable programs, subroutines, and functions for the modelling of materials. MAP owes its origins to the National Physical Laboratory and the Phase Transformations Group of the University of Cambridge. It is a non-profit venture, sponsored originally by the Engineering and Physical Sciences Research Council (EPSRC) of the United Kingdom.

Material Analysis in the News

December 31, 2019. A Sacramento, California electricity provider has installed an experimental cooling system: panels that stay colder than their surroundings, even under the blazing hot sun, without consuming energy. The panels emerged from a discovery at Stanford University in California. In 2014, researchers there announced that they had created a material that stayed colder than its surroundings in direct sunlight.

January 6, 2020.  A new study offers a nanoscopic view of complex oxides, which have great potential for advanced microelectronics. Analysis from a team led by Argonne researchers reveals never-before-seen details about a type of thin film being explored for advanced microelectronics.

January 8, 2020. Hotter objects typically glow brighter than cooler ones, making them stand out in infrared images. But a newly designed coating bucks the rule that hotter equals brighter. A coating of samarium nickel oxide counteracts hotter objects’ tendency for brighter thermal radiation, and could camouflage objects from infrared cameras.
