Producing resource-saving batteries from wood waste

Novel digestion process

05-Dec-2023 - Batteries are crucial for the change in mobility and energy supply. Lithium-ion batteries have been the most commonly used battery type in electric cars to date, but the availability of raw materials is a major challenge here. Researchers at Aalen University, led by Prof. Dr. Volker Knoblauch, ...

Antibacterial Polymers

Surprising antibacterial activity and selectivity of hydrophilic phosphonium polymers

10-Sep-2018 - Artificial polymers, like antibiotic peptides, need both hydrophobic and hydrophilic domains in their molecular structure to exert antibacterial activity. Now, researchers from Canada have synthesized a phosphonium polymer that challenges this view. As outlined in the journal Angewandte Chemie, ...

02-Jun-2017 - Researchers from Concordia's Department of Building, Civil and Environmental Engineering (BCEE) in collaboration with Bio-Terre Systems Inc. are taking the fight against global warming to colder climes. Their weapon of choice? Cold-loving bacteria. In a study authors Rajinikanth Rajagopal, David ...

Top 12 ways the world can eliminate agriculture's climate footprint

Impact of eating less red meat, more efficient production and use of fertilizer calculated; emissions can be cut while boosting food production globally

28-Apr-2014 - Annual carbon emissions from global agriculture can be reduced by as much as 50 to 90 percent by 2030—the equivalent of removing all the cars in the world—according to a comprehensive new report released by Climate Focus and California Environmental Associates. The study highlights twelve key ...

Sugar, not oil

27-Mar-2014 - No more oil – renewable raw materials are the future. This motto not only applies to biodiesel, but also to isobutene, a basic product used in the chemical industry. In a pilot plant researchers now want to obtain this substance from sugar instead of oil for the first time. And in order not to ...

'Wired microbes' to generate electricity from sewage

Interdisciplinary team creates 'microbial battery' driven by naturally occurring bacteria that evolved to produce electricity as they digest organic material

19-Sep-2013 - Engineers at Stanford University have devised a new way to generate electricity from sewage using naturally-occurring "wired microbes" as mini power plants, producing electricity as they digest plant and animal waste. In a paper published in the Proceedings of the National Academy of Sciences, ...

Measurement method for determining concentrations in dust deposition

24-Nov-2003 - The parts of this guideline describe complete methods to determine the metals and metalloids in the suspended particulate matter of the ambient air and in the dust deposition, which enter ambient air from combustion plants and during their manufacture and processing. The selection of components ...
