Department of Chemical Engineering Professor Zachary Smith is working on new polymeric membranes that can greatly reduce energy use in chemical separations.Eric Brown | MIT Industrial Liaison Program November 15, 2017There are scores of promising technologies under development that can reduce energy consumption or capture carbon in fields including biotech, computer science, nanotechnology, materials science, and more. Not all will prove feasible, but with a little funding and nurturing, many could help solve the planet’s grand challenge.One such solution is emerging from new approaches t...

MBR membrane bioreactor is a new and efficient wastewater treatment process, which greatly improves the solid-liquid separation capacity. The treated water quality standards exceed the national first-class A. Then, what environmental protection devices and components are included in the MBR membrane bioreactor? What are its technological characteristics, advantages, uses and scope of application?MBR membrane bioreactor (MBR MBR MBR MBR) is a new type of high-efficiency wastewater treatment process which combines high-efficiency membrane separation technology with traditional activated sludge p...

Could a modernist food technique create a new, less wasteful way to package water? Appliance Science looks at the curious chemistry of spherification.A sphere of water created using spherification.I just drank a cup of water. Nothing unusual there, but this was without a cup or other container. Instead, the water was held in a clear, edible membrane that I popped into my mouth and bit down on. It tasted, well, just like water, because this clear sphere was made just from water and two tasteless chemicals.I made this strange sphere myself, using a process called spherification. Using the reacti...

It's still new in the automotive space, and Ford's taken a unique approach to its use.You won't even be able to tell anything's different, unless you can somehow observe molecular structures with your naked eye.Graphene is a single layer of carbon atoms, and its benefits could spread across many industries. While it's normally praised for its strength and conductivity, Ford plans on using it for a slightly different, but still beneficial purpose.Fordannounced this week that it intends to use graphene under the hood of future Ford vehicles. But its initial use won't be f...

MIT engineers have found a way to directly “pinprick” microscopic holes into graphene as the material is grown in the lab. With this technique, they have fabricated relatively large sheets of graphene (“large,” meaning roughly the size of a postage stamp), with pores that could make filtering certain molecules out of solutions vastly more efficient.Such holes would typically be considered unwanted defects, but the MIT team has found that defects in graphene — which consists of a single layer of carbon atoms — can be an advantage in fields such as dialysis. Typically, much thicker polymer membr...
