Finding local fertilizer alternatives

February 12, 2019

Professor Antoine Allanore and his research team have demonstrated a new method of fertilizer production can better suit the needs of farms in Africa and around the globe.   more

A new way to provide cooling without power

December 5, 2018

MIT researchers have devised a new way of providing cooling on a hot sunny day, using inexpensive materials and requiring no fossil fuel-generated power. The passive system, which could be used to supplement other cooling systems to preserve food and medications in hot, off-grid locations, is essentially a high-tech version of a parasol.   more

A new concept for thermal energy storage

November 30, 2018

More than half of all the energy used to power mechanical, chemical, and other processes is expelled into the environment as heat. Power plants, car engines, and industrial processes, for example, produce vast amounts of heat but use a relatively small fraction of it to actually do work. And…   more

Aluminum production could get much better for the environment

May 11, 2018

You probably don’t think about aluminum very much. But you should. The ubiquitous metal is in airplanes, iPhones, and engine blocks made by General Motors, to name just a few uses. A 12-inch MacBook, for example, consists of over half a pound of aluminum. And since the late 19th century, the…   more

Investing in Tech That’s Worth the Wait

February 23, 2018

Innovations in fields like energy and transportation often take time—and extra support—to develop. The Engine at MIT is helping them make the leap from the lab to the marketplace. Liquid separation wouldn’t top most people’s lists of world-changing technologies. But consider this: every…   more

A new approach to rechargeable batteries

January 24, 2018

A type of battery first invented nearly five decades ago could catapult to the forefront of energy storage technologies, thanks to a new finding by researchers at MIT. The battery, based on electrodes made of sodium and nickel chloride and using a new type of metal mesh membrane, could be used…   more

New technique allows rapid screening for new types of solar cells

December 21, 2017

The worldwide quest by researchers to find better, more efficient materials for tomorrow’s solar panels is usually slow and painstaking. Researchers typically must produce lab samples — which are often composed of multiple layers of different materials bonded together — for extensive testing.…   more

10 years of energy research at MIT

November 14, 2017

Q: What are some of the most significant research impacts the MIT energy community has made over the past decade? A: While the horizon for the majority of energy research we do here at MIT is generally at least several decades, some researchers have already been able to translate their…   more

2017 Fall Wulff Lecture

November 6, 2017

  Fantastic Feather: Form and Function When we think of birds, we think of feathers. Feathers give birds their color, from the bright red of a male Cardinal to the iridescent reds and greens of Ruby-throated Hummingbirds. Feathers keep birds warm and dry: down…   more

Will metal supplies limit battery expansion?

October 12, 2017

The dramatic rise in production of electric vehicles, coupled with expected growth in the use of grid-connected battery systems for storing electricity from renewable sources, raises a crucial question: Are there enough raw materials to enable significantly increased production of lithium-ion…   more

Making a pledge for the climate with our careers

September 26, 2017

Jeremy Poindexter, a graduate student in DMSE, recently published a piece titled "Making a pledge for the climate with our careers" in The Tech. "As I enter my fifth year as a PhD student at MIT and contemplate my post-graduation career trajectory, I chuckle when rereading these old words…   more

Projects make inroads on global food and water challenges

September 25, 2017

With goals that include finding better ways to purify and desalinate water, improving fertilizer production, and preventing food contamination, nearly two dozen research teams presented updates on their work at a day-long event on Sept. 15. The workshop featured the recipients of grants from the…   more

Designing the Circular Economy

August 30, 2017

In the circular economy, waste is minimized through reuse, reducing resource consumption by regeneratively cycling economic, natural, and social capital. By reducing this connection between production and consumption, a more sustainable balance can be reached in light of increasing populations…   more

Green Labs contest: A certified success

December 21, 2016

The Schuh Lab received an honorable mention for its participation in the Green Labs contest. This contest challenged MIT labs to find and maintain solutions to reduce waste and hazardous materials and to conserve water and energy. "The Schuh Lab in the Department of Materials Science and…   more

New Smelting Method Developed by Prof Don Sadoway

August 25, 2016

Professor Donald Sadoway and a team of researchers intended to create a new type of battery, but what they did instead was discover a new method of smelting certain metals without releasing any greenhouse gas emissions. This discovery could potentially lead to new ways of smelting other common…   more

MADMEC spinoff AquaFresco was a finalist in MIT $100k Competition

July 5, 2016

AquaFresco is still making waves in their endeavors to reduce waterwaste by recycling water used when cleaning laundry. Since their MADMEC victory is 2014, they've been turning heads with their innovative ideas and picking up more victories and funding from other competitions. They were recently…   more
