Improving rechargeable batteries by focusing on graphene oxide paper
An engineering team has discovered some of graphene oxide's important properties that can improve sodium- and lithium-ion flexible batteries.
'Tipping points' for sea level rise related flooding determined
By 2050, a majority of US coastal areas are likely to be threatened by 30 or more days of flooding each year due to dramatically accelerating impacts from sea level rise, according to a new study.
Glimpsing pathway of sunlight to electricity
Four pulses of laser light on nanoparticle photocells in a spectroscopy experiment has opened a window on how captured sunlight can be converted into electricity. The work, which potentially could inspire devices with improved efficiency in solar energy conversion, was performed on photocells that used lead-sulfide quantum dots as photoactive semiconductor material.
