In a paper appearing in Nature's Scientific Reports, Dr Ramesh Mani, professor of physics and astronomy at Georgia State University, reports that a giant magnetoresistance effect depends on the physical size of the device in the GaAs/AlGaAs semiconductor system.

The Thomson Reuters Top 100 global innovators represent the vanguard of 21st century innovation. They are a group of businesses and research institutions that recognize that great ideas are only half of the strategic equation. The other essential component is the protection of those ideas with intellectual property rights, so they can be commercialized and leveraged around the world – therefore reaching their full potential.

This tutorial at this year's Fall MRS Meeting will cover the fundamentals of how epitaxial interfaces in complex oxides are fabricated, specifically addressing the strengths and weaknesses of pulsed laser deposition (PLD) and molecular beam epitaxy (MBE). The tutorial is suitable for scientists interested in an introduction to modern oxide film growth, but also provides direct comparisons from both the MBE and PLD communities regarding the strengths of each technique.
The Thermo Scientific™ MAGCIS™ dual mode ion source enables depth profiling analysis and surface cleaning of both soft and hard materials on the same XPS instrument. Switching between gas cluster sputtering and monatomic sputtering is handling completely by the Avantage data system, and can be done in a matter of seconds.

EPFL scientists have provided the first evidence ever that it is possible to generate a magnetic field by using heat instead of electricity. The phenomenon is referred to as the Magnetic Seebeck effect or ‘thermomagnetism’.

Whilst experts in embedded systems still argue, Toyota have been found liable for a 2007 fatal car crash. Bugs in the source code relating to the throttle control being highlighted. As we move towards self-driving cars it is not just software and electronic reliability issues that need addressing. A recent conference on intelligent transport systems discussed how self-driving cars deal with “exceptions”. Is there a danger that the technology will over de-skill the task of driving? How does the self-driving car recognise a crisis beyond its program capabilities and safely hand over control to the human driver?

It is not quite the same as Deep Thought which took 7.5 million years to compute and check its answer. Nor is quark decay quite the ultimate question of life, the universe and everything - though certainly a part. Scientists at Brookhaven National Laboratory have been using super computers to crunch the numbers since 1964. Gratifyingly after this time working on matter antimatter symmetry calculations they think that they have solved half of the problem.
