Profile
The National Science Foundation is an independent U.S. federal agency established by Congress in the NSF Act of 1950 "to promote progress of science," and "advance national health, prosperity, and welfare," and "to secure the national defense." NSF provides financial support for fundamental research and education across all fields of science and engineering. The majority of the funds are provided to support basic research performed in U.S. academic institutions.

Aluminum could give boost to capacity, power of lithium-ion batteries
Researchers have created an electrode made of nanoparticles with a solid shell, and a "yolk" inside that can change size again and again without affecting the shell.12 Aug 2015
Progress in harvesting energy from bumps in the road
This energy-harvesting shock absorber works by translating the vertical vibrations of the suspension into rotational motion that turns a generator.31 Jul 2015
Tough biogel structures produced by 3-D printing
Researchers have developed a new way of making tough biocompatible materials, called "hydrogels," into complex and intricately patterned shapes.29 Jul 2015
Anelastic nanowires could enable stretchable electronic devices
Researchers have found that nanoscale wires (nanowires) made of common semiconductor materials have a pronounced anelasticity - meaning that the wires, when bent, return slowly to their original shape rather than snapping back quickly.14 Jul 2015
Could black phosphorus be the next silicon?
As scientists continue to hunt for a material that will make it possible to pack more transistors on a chip, new research adds to evidence that black phosphorus could emerge as a strong candidate.9 Jul 2015
New storage cell for solar energy storage, nighttime conversion
Researchers have developed a new energy cell that can store large-scale solar energy even when it's dark.30 Jun 2015
Robust new process forms 3D shapes from flat sheets of graphene
Researchers have developed a new approach for forming 3D shapes from flat, 2D sheets of graphene, paving the way for future integrated systems of graphene-MEMS hybrid devices and flexible electronics.26 Jun 2015
New microchip improves future of self-powered wearable technology
Energy from your body heat and motion could fuel the future of preventative health care.16 Jun 2015
Engineer creates origami battery
Origami, the Japanese art of paper folding, can be used to create beautiful birds, frogs and other small sculptures. Now a Binghamton University engineer says the technique can be applied to building batteries, too.15 Jun 2015

Swelling magnets to energise the world
A new class of magnets that expand their volume when placed in a magnetic field and generate negligible amounts of wasteful heat during energy harvesting, has been discovered by researchers.1 Jun 2015
How to make continuous rolls of graphene
All the possible uses for graphene face the same big hurdle: the need for a scalable and cost-effective method for continuous manufacturing of graphene films.25 May 2015

Chemists cook up three atom-thick electronic sheets
Making thin films out of semiconducting materials is analogous to how ice grows on a windowpane: When the conditions are just right, the semiconductor grows in flat crystals that slowly fuse together, eventually forming a continuous film.4 May 2015
For batteries, one material does it all
Engineers have created a battery that is made entirely out of one material, which can both move electricity and store it.29 Apr 2015
Better battery imaging paves way for renewable energy future
In a move that could improve the energy storage of everything from portable electronics to electric microgrids, University of Wisconsin-Madison and Brookhaven National Laboratory researchers have developed a novel X-ray imaging technique to visualize and study the electrochemical reactions in lithium-ion rechargeable batteries containing a new type of material, iron fluoride.27 Apr 2015
Engineer improves rechargeable batteries with nano sandwich
The key to better cellphones and other rechargeable electronics may be in tiny "sandwiches" made of nano sheets.15 Apr 2015
Discovery may be breakthrough for hydrogen-fueled vehicles
Researchers discovered a way to create hydrogen fuel using a biological method that greatly reduces the time and money it takes to produce the zero-emissions fuel. This method uses abundantly available corn stover - the stalks, cobs, and husks - to produce the hydrogen.13 Apr 2015
Inkjet-printed liquid metal could bring wearable tech
New research shows how inkjet-printing technology can be used to mass-produce electronic circuits made of liquid-metal alloys for "soft robots" and flexible electronics.13 Apr 2015
First metal-free catalyst for rechargeable zinc-air batteries
Researchers have made what they believe is the first metal-free bifunctional electrocatalyst that performs as well or better than most metal and metal oxide electrodes in zinc-air batteries.
