Customising an electronic material
Scientists have gained a fundamental understanding of a highly promising material that could be suited to future data storage applications. Their experiments with strontium-iridium oxide, Sr2IrO 4 , investigated both the magnetic and electronic properties of the material as a thin film.

Transistor-integrated cooling for a more powerful chip
Researchers have created a single chip that combines a transistor and micro-fluidic cooling system. Managing the heat generated in electronics is a huge problem, especially with the constant push to reduce the size and pack as many transistors as possible in the same chip. The whole problem is how to manage such high heat fluxes efficiently.
