New metal-mesh membrane could solve longstanding problems and lead to inexpensive power storage.David L. Chandler | MIT News Office January 22, 2018A 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 for grid-scale installations to make intermittent power sources such as wind and solar capable of delivering reliable baseload electricity.The findings ...

Proponents of clean energy will soon have a new source to add to their existing array of solar, wind, and hydropower: osmotic power.BY ANTHONY CUTHBERTSON ON 7/14/16 AT 4:03 AMRiver mouths around the world may soon provide an abundant new source of clean energy after scientists developed an efficient system to generate electricity from salt water.Research published this week in the journal Nature outlines how significant amounts of power can be generated from a natural phenomenon that occurs when fresh water comes into contact with seawater through a membrane.The process of osmosis that occurs...

February 16, 2017Posted in: Healthcare, IBM 5 in 5, SystemsJust last month, IBM released its “5 in 5” predictions, an exercise to identify five innovations that will have an impact on society in five years. Among the five, it was predicted that, with the help of IBM “lab-on-a-chip” technology, doctors could have a device that isolates tiny bioparticles from bodily fluids to reveal signs of diseases like cancer, before symptoms appear. One of the goals in this project is to shrink down to a few silicon chips many of the components and processes necessary to analyze a disease that would normally...

Material can filter nanometer-sized molecules at 10 to 100 times the rate of commercial membranes.Jennifer Chu | MIT News Office June 28, 2017Dialysis, in the most general sense, is the process by which molecules filter out of one solution, by diffusing through a membrane, into a more dilute solution. Outside of hemodialysis, which removes waste from blood, scientists use dialysis to purify drugs, remove residue from chemical solutions, and isolate molecules for medical diagnosis, typically by allowing the materials to pass through a porous membrane.Today’s commercial dialysis membranes s...
