MoS2/Graphene Composite Materials As High-Performance Anodes For Li-ion Batteries

A pair of researchers from Zhejiang University (China) have synthesized layered MoS2/graphene (MoS2/G) composites using a facile biomolecular-assisted process for use as high-performance anode materials in Li-ion batteries. The MoS2/G composite with a Mo:C molar ratio of 1:2 exhibited the highest specific capacity of ~1100 mAh/g at a current of 100 mA/g, as well as…

FAA Grant Helps Portland Jetport Save 50,000 Gallons Of Oil A Year With Geothermal Heating And Cooling

A group of officials gets a look at upgrades under way at the Portland Jetport.

Portland, Maine’s new airport expansion is to be the first in the country to use a dead-simple but often overlooked technology to significantly reduce its heating and cooling bills. They’re calling it a geothermal system, but it’s not like the kind that produce power in Iceland; it’s more properly called a “ground-source heat pump.” With…
