Cleaning up oil using magnets
In the future, it could be possible to remove oil spills on the surface of the ocean by using magnets. An interdisciplinary group of researchers at Friedrich-Alexander-Universität Erlangen-Nürnberg led by Professor Dr. Marcus Halik has developed functionalized iron oxide particles that can attract any types of hydrocarbons. The magnetic particles and their shells can then be removed from the water relatively simply and in an environmentally friendly manner and can even be reused after being cleaned. (2019-04-01)

The success of an environmental charge
In October 2015, England introduced a charge for single-use plastic bags in supermarkets. An international research team, including Elena Sautkina from the Higher School of Economics, has conducted a mixed-methods longitudinal study and determined the extent to which British people approved of this policy initiative, and whether they were ready to support other environmental charges. The results were published in Frontiers in Psychology journal. (2019-03-22)

Monitoring air pollution after Hurricane Maria
When Hurricane Maria struck Puerto Rico on Sept. 20, 2017, the storm devastated the island's electrical grid, leaving many people without power for months. This lack of electricity, as well as other storm-related damage, prevented air-quality monitoring in many areas. Now researchers have shown that low-cost sensors that run on solar energy can be used to monitor air pollution after a disaster. They report their results in ACS Earth and Space Chemistry. (2018-10-31)

Alaskan microgrids offer energy resilience and independence
The electrical grid in the contiguous United States is a behemoth of interconnected systems; if one section fails, millions could be without power. Remote villages in Alaska provide an example of how safeguards could build resilience into a larger electrical grid. These communities rely on microgrids -- small, local power stations that operate autonomously. Recent articles in the Journal of Renewable and Sustainable Energy provide reviews of energy technologies and costs for microgrids in Alaska. (2017-12-26)
