On the top row are two images of a nanomesh bilayer of PDMS cylinders in which the top layer is perpendicular to the complex orientation of the bottom layer. The bottom images show well-ordered nanomesh patterns of PDMS cylinders. The images on the right show zoomed-in views of the images on the left.

Self-stacking nanogrids

Polymer nanowires that assemble in perpendicular layers could offer route to tinier chip components.

This GridForm model of a village in Bihar, India, shows the optimal layout of hardware for the load profiles of the community. Each building, color-coded by the cost (in Indian rupees) of supplying electricity to that structure, is wired to a central generation/storage node (solid lines), and the nodes are connected to each other (dotted lines).

Going off grid: Tata researchers tackle rural electrification

At MIT’s Tata Center for Technology and Design, researchers are exploring ways to extend electricity access to rural communities in India using microgrids.

This diagram shows how an electrical voltage can be used to modify the oxygen concentration, and therefore the phase and structure, of strontium cobaltites. Pumping oxygen in and out transforms the material from the brownmillerite form (left) to the perovskite form (right).

Switchable material could enable new memory chips

Small voltage can flip thin film between two crystal states — one metallic, one semiconducting.

The layer-by-layer solar thermal fuel polymer film comprises three distinct layers (4 to 5 microns in thickness for each). Cross-linking after each layer enables building up films of tunable thickness.

A new way to store solar heat

Material could harvest sunlight by day, release heat on demand hours or days later.

This diagram illustrates the principle behind the proposed energy-harvesting system. Two metal electrodes made of lithium-alloyed silicon form a sandwich around a layer of electrolyte, a polymer that ions (charged atoms) can move across. When the sandwich is bent, unequal stresses cause lithium ions to migrate across the electrolyte, producing a compensating electron current that can be harnessed ...

Harnessing the energy of small bending motions

New device could provide electrical power source from walking and other ambient motions.

Close-up image of part of the shell of a chiton (Acanthopleura granulata) shows the two kinds of sensory organs that cover the shell surface. The eyes are the dark bumps with shiny centers. The exact function of other sensory organs called aesthetes (small bumps with black centers) is not yet known.
