Someday, microbial cyborgs -- bacteria combined with electronic devices -- could be useful in fuel cells, biosensors and bioreactors. But first, scientists need to develop materials that not only nurture the microbes, but also efficiently and controllably harvest the electricity or other resources they make. Now, researchers reporting in ACS Applied Materials & Interfaces have developed one such material that enabled them to create a programmable 'biohybrid' system that conducts electrons from electricity-producing (exoelectrogenic) bacteria.
A literal "trick of the light" can detect imperfections in next-gen solar cells, boosting their efficiency to match that of existing silicon-based versions, researchers have found.
ETH researchers analysed various possibilities for reducing the net CO2 emissions of the chemical industry to zero. Their conclusion? The chemical industry can in fact have a carbon-neutral future.
One strategy to make biofuels more competitive is to make plants do some of the work themselves. Scientists can engineer plants to produce valuable chemical compounds, or bioproducts, as they grow. Then the bioproducts can be extracted from the plant and the remaining plant material can be converted into fuel. But one important part of this strategy has remained unclear -- exactly how much of a particular bioproduct would plants need to make in order to make the process economically feasible?
Researchers have designed a machine learning method that can predict battery health with 10x higher accuracy than current industry standard, which could aid in the development of safer and more reliable batteries for electric vehicles and consumer electronics.
Sustainable energy storage is in great demand. Researchers at Uppsala University have therefore developed an all-organic proton battery that can be charged in a matter of seconds. The battery can be charged and discharged over 500 times without any significant loss of capacity. Their work has been published in the scientific journal Angewandte Chemie.
Low-carbon technologies that are smaller scale, more affordable, and can be mass deployed are more likely to enable a faster transition to net-zero emissions, according to a new study by an international team of researchers. Innovations ranging from solar panels to electric bikes also have lower investment risks, greater potential for improvement in both cost and performance, and more scope for reducing energy demand -- key attributes that will help accelerate progress on decarbonization.
A major new study by an interdisciplinary team of researchers finds that it is possible -- and critical -- to bring industrial greenhouse gas emissions to net zero by 2070. Published Sunday in Applied Energy, the study assesses the range of technologies and policies interventions available to enable global industry decarbonization. This paper was the result of a collaboration among almost two dozen leading technical experts, led by Jeffrey Rissman of Energy Innovation and coauthored by Resources for the Future (RFF) Senior Fellow Dallas Burtraw.
At the BESSY II storage ring, a team has shown how the helicity of circularly polarized synchrotron radiation can be switched faster - up to a million times faster than before. They used an elliptical double-undulator developed at HZB and operated the storage ring in the so-called two-orbit mode. This is a special mode of operation that was only recently developed at BESSY II and provides the basis for fast switching.
The BIOSAHE research group at the University of Cordoba developed a methodology to assess waste and determine the most appropriate valorization paths.
