U of A researchers have identified an inexpensive way to boost the efficiency of a process used to create hydrogen, a clean, renewable fuel.
The ecological bio-production of xylitol and cellulose nanofibers from material produced by the paper industry has been achieved by a Japanese research team. This discovery could contribute to the development of a greener and more sustainable society. The findings were published on March 4, in Green Chemistry.
With an estimated daily fuel demand of more than 5 million barrels per day, the global aviation sector is incredibly energy-intensive and almost entirely reliant on petroleum-based fuels. However, a new analysis by Berkeley Lab shows that sustainable plant-based bio-jet fuels could provide a competitive alternative to conventional fuels if current development and scale-up initiatives continue to push ahead successfully.
Researchers have discovered that a bacterium found in camel crickets is capable of breaking down lignin -- the stuff that makes wood tough -- opening new research pathways for the development of biofuels and chemical manufacturing. The study also highlights the potential inherent in using ecosystem analysis as a tool for targeting research into the identification of commercially valuable microorganisms with industrial applications.
Researchers at the University of Warwick have been inspired by the unique movement of trembling aspen leaves, to devise an energy harvesting mechanism that could power weather sensors in hostile environments and could even be a back-up energy supply that could save and extend the life of future Mars rovers.
Splitting water into hydrogen and oxygen presents an alternative to fossil fuels, but purified water is a precious resource. A Stanford-led team has now developed a way to harness seawater -- Earth's most abundant source -- for chemical energy.
A team of scientists including researchers at the U.S. Department of Energy's Brookhaven National Laboratory and SLAC National Accelerator Laboratory have identified the causes of degradation in a cathode material for lithium-ion batteries, as well as possible remedies. Their findings, published on March 7, 2019, in Advanced Functional Materials, could lead to the development of more affordable and better performing batteries for electric vehicles.
NIMS, the University of Tokyo, Niigata University and RIKEN jointly designed a multilayered metamaterial that realizes ultra-narrowband wavelength-selective thermal emission by combining the machine learning (Bayesian optimization) and thermal emission properties calculations (electromagnetic calculation). The joint team then experimentally fabricated the designed metamaterial and verified the performance. These results may facilitate the development of highly efficient energy devices.
In a paper to be published in the forthcoming issue in NANO, researchers from the China University of Petroleum (East China) have summarized the recent advances in application of 2D nanomaterials on the electrode materials of lithium-ion batteries, owing to their compelling electrochemical and mechanical properties that make them good candidates as electrodes in lit-ion batteries for high capacity and long cycle life.
The cryptocurrency Bitcoin is known for its energy footprint. Now, researcher Alex de Vries, from PricewaterhouseCoopers (PwC) in the Netherlands, suggests that renewable hydropower production cannot supply the large quantities of energy needed to power machinery used to validate Bitcoin transactions. In a Commentary publishing March 14 in the journal Joule, he highlights the vast quantities of electronic waste produced by the Bitcoin network and calls for alternative strategies to curb the cryptocurrency's environmental impact.
