Semiconductor works better when hitched to graphene

Graphene – a one-atom-thick sheet of carbon with highly desirable electrical properties, flexibility and strength – shows great promise for future electronics, advanced solar cells, protective coatings and other uses, ...

Moving origami techniques forward for self-folding 3-D structures

Though the past 15 years have seen an exciting run of creative scientific advances in fabricating three-dimensional (3D) structures by self-folding of 2D sheets, the complexity of structures achieved to date falls far short ...

Versatile polymer film synthesis method invented

(Phys.org) —Forming perfect porous polymer films is not enough; they need both large and small pores, and the process of making them needs to be simple, versatile and repeatable. Creatively combining already established ...

New technology to enable development of 4G solar cells

Professor Ravi Silva of the University of Surrey's Advanced Technology Institute has identified the range of combinations of organic and inorganic materials that will underpin new 4th generation solar cell technology – ...

Artificial muscle contracts and expands with changes in humidity

(Phys.org) —A small plastic strip can do "weight training" to effortlessly lifts many times its own weight, driven by cyclic changes in the humidity of the surrounding air. This strong "artificial arm" is based on the interaction ...
