The trend toward energy self-sufficient probes and ever smaller mobile electronics systems continues unabated. They are used, for example, to monitor the status of the engines on airplanes, or for medical implants. They gather the energy they need for this from their immediate environment - from vibrations, for instance. Fraunhofer researchers have developed a process for the economical production of piezoelectric materials.
Treatment plants cannot completely keep microplastics out of wastewater by conventional means. This is one of the results of a pilot study. The findings will be used to better protect flora and fauna in rivers and seas.
Today, the city of Rome welcomed an important new initiative for the large-scale integration of grids and of renewables sources into Europe's energy mix, with nearly 40 leading organisations from research, industry, utilities, transmission systems operators announcing their united goal to find the BEST PATHS to deliver affordable, reliable power in Europe from coast to coast.
By remotely 'combing' the atmosphere with a custom laser-based instrument, researchers have developed a new technique that can accurately measure - over a sizeable distance - amounts of several of the major greenhouse gases implicated in climate change.
Farmland is vanishing in part because the salinity in the soil is rising as a result of climate change and other man-made phenomena. Researchers propose a new concept for breeding salt- tolerant plants as a way to contribute to global efforts for sustainable food production.
Developing nations represent a large and rapidly growing share of the world?s clean energy investment, according to Climatescope 2014, a landmark study released today. The results suggest renewable technologies can be just as cost-competitive in emerging parts of the world as they are in richer nations.
Multiple pathways exist to a low greenhouse gas future, all involving increased efficiency and a dramatic shift in energy supply away from fossil fuels. A new tool 'SWITCH' enables policymakers and planners to assess the economic and environmental implications of different energy scenarios.
Researchers have pioneered a new approach to manufacturing solar cells that requires less silicon and can accommodate silicon with more impurities than is currently the standard. Those changes mean that solar cells can be made much more cheaply than at present.
Scientists combined hydrogen with its heavier sibling deuterium and created a novel, disordered, 'Phase IV'-material. The molecules interact differently than have been observed before, which could be valuable for controlling superconducting and thermoelectric properties of new materials.
Sscientists have developed geochemical tracers to identify hydraulic fracturing flowback fluids that have been spilled or released into the environment. The tracers have been field-tested at two sites and can distinguish fracking fluids from wastewater versus conventional wells or other sources. They give scientists new forensic tools to detect if fracking fluids are escaping into water supplies and what risks, if any, they might pose.
