Tuneable reverse photochromes in the solid state

A new technique allows the design of solid materials that are coloured in the dark. This can have applications in rewritable displays or optical data storage systems.

Nanomaterials give plants 'super' abilities (w/video)

Researchers report the development of plants that can make nanomaterials called metal-organic frameworks (MOFs) and the application of MOFs as coatings on plants. The augmented plants could potentially perform useful new functions, such as sensing chemicals or harvesting light more efficiently.

Harnessing the spin of electrons to power tech devices

Scientists are using principles in quantum science and engineering to build a graphene-based logic device. This new technology will improve the energy efficiency of battery-dependent devices from cell phones to computers.

Radical steps toward clean encapsulation

Chemists use free radicals to produce polymers strong enough to encapsulate drugs while remaining degradable.

Right combination of crystal grains makes superior shape memory alloys

Researchers have shown, through a supercomputer simulation, that high strength and shape memory can be realized at the same time by combining crystal grains of different sizes, a feat previously thought impossible.

Smart liquid goes dark in the heat

Nanowires that form and disperse as the temperature changes form the basis of a robust thermochromic liquid.

Shape-changing plane wing

Assembled from tiny identical pieces, the wing could enable lighter, more energy-efficient aircraft designs.
