MIT team develops first supercapacitor made entirely from neat MOFs, without conductive additives or binders

Green Car Congress

Researchers at MIT have shown that a MOF (metal-organic framework) with high electrical conductivity—Ni 3 (2,3,6,7,10,11-hexaiminotriphenylene) 2 (Ni 3 (HITP) 2 )—can serve as the sole electrode material in a supercapacitor. Comparison of areal capacitances among various EDLC materials. —Alexandru Vlad.

U Chicago, MIT study suggests ongoing use of fossil fuels absent new carbon taxes

Green Car Congress

A paper by a team from the University of Chicago and MIT suggests that technology-driven cost reductions in fossil fuels will lead to the continued use of fossil fuels—oil, gas, and coal—unless governments pass new taxes on carbon emissions. Their analysis is published in the Journal of Economic Perspectives.

RPI researchers develop safe, long-cycling Li-metal rechargeable battery electrode; demonstrate Li-carbon battery

Green Car Congress

Ce 0.02 (PO 4 ) 3 /C) measured at comparable current densities has been included for comparison. What is different is that the electrode material that stores the Li is all-carbon for both the anode as well as the cathode. The performance of various other cathode materials (LiCoO 2 , LiFePO 4 , LiNi 0.75 O 2 and Li 3 V 1.98

MIT Researchers Find That Elastic Energy Storage Systems Built With Carbon Nanotubes Could Match Li-ion Battery Energy Densities

Green Car Congress

Densities for steel springs and Li-ion batteries provide a comparison. Carol Livermore, associate professor of mechanical engineering and her team used an ordered grouping of carbon nanotubes (CNT) as a spring to store elastic energy for later use—much as a steel spring stores energy in a mechanical watch.

AI and Robots Are a Minefield of Cognitive Biases

Cars That Think

We judge robots’ or AI’s tasks in comparison to humans. I believe many were impressed to see the Mini Cheetah , developed in my MIT Biomimetic Robotics Laboratory, perform a backflip. As the 18 th century philosopher David Hume said, “There is a universal tendency among mankind to conceive all beings like themselves.

New Study Finds Flaw in Carbon Accounting for Bioenergy, Another Contends That Indirect Land Use Change Emissions for Biofuels Will Be Up To Twice Direct Land Use Change Emissions

Green Car Congress

A separate paper published online in Science Express by researchers from the Marine Biological Laboratory, Woods Hole and MIT concludes that indirect land use change associated with global biofuels programs will be responsible for substantially more carbon loss (up to twice as much) than direct land use. issue of the journal Science.
