Range-doubling lithium metal batteries 'build themselves' in lithium ion manufacturing machinery

Lithium metal batteries, capable of doubling the capacity of today’s standard lithium-ion cells, can be built utilizing much of the current battery manufacturing system, a finding from University of Michigan researchers that removes a major hurdle for automakers looking to embrace the next major evolution in energy storage technology for electric vehicles.

Solar-powered wastewater treatment coupled with energy and nutrient recovery

If a harmful algal bloom has ever closed your favorite lake-side beach or caused your municipality to issue a drinking water warning, a possible cause is excess nitrogen, phosphorous and organic nutrients. These nutrients are present in the surface water runoff from farms, factories, and our own well-fertilized backyards, and the excess nutrient build-up has been identified as a major cause of eutrophication, or the explosive growth of algae in water bodies. This can pose environmental threats to aquatic species and result in health risks in human-beings (see figure 1).
