New research from North Carolina State University and UNC-Chapel Hill reveals that energy is transferred more efficiently inside of complex, three-dimensional organic solar cells when the donor molecules align face-on, rather than edge-on, relative to the acceptor. This finding may aid in the design and manufacture of more efficient and economically viable organic solar cell technology.

Researchers at the Georgia Institute of Technology and the Joint BioEnergy Institute have engineered a bacterium to synthesize pinene, a hydrocarbon produced by trees that could potentially replace high-energy fuels, such as JP-10, in missiles and other aerospace applications. With improvements in process efficiency, the biofuel could supplement limited supplies of petroleum-based JP-10, and might also facilitate development of a new generation of more powerful engines.

Osmosis, a vital biological process, is finding its way to the clean and renewable energy technology. Researchers at the Chemical and Biomolecular Engineering Department at the National University of Singapore and at the Water Desalination & Reuse Center at King Abdullah University of Science and Technology fabricated polyethersulfone (PES) thin film composite membranes with hollow fiber supports in order to achieve a membrane with high mechanical strength and high flux—a membrane specifically designed to optimally procure the osmotic energy generated by seawater brine.

Increasing energy efficiency in buildings requires substantial coordination between design engineers and architects. Researchers at Princeton University applied a common structural form-finding technique to predict the equilibrium shapes and elastic energies of dielectric elastomer minimum energy structures (DEMES).

In a new study, researchers from Imperial College Business School carried out a comprehensive nationwide analysis of the UK fleet of wind turbines, using local wind speed data from NASA. They showed that the turbines will last their full life of about 25 years before they need to be upgraded.
