Researchers have established an approach to identify the orientation of molecules and chemical bonds in crystalline organic-inorganic hybrid thin films deposited on substrates using Fourier transform infrared spectroscopy (FT-IR) and polarized infrared light with a 3D-printed attenuated total reflectance (ATR) unit. This inexpensive method with laboratory-grade equipment quickly reaches the crystal-structure model of even extremely thin films of less than 10 nm.
An incredibly light new material that can reduce aircraft engine noise and improve passenger comfort has been developed at the University of Bath. The graphene oxide-polyvinyl alcohol aerogel weighs just 2.1kg per cubic metre, making it the lightest sound insulation ever manufactured.
Researchers at the University of Houston, in collaboration with Rice University, published a paper detailing how to improve energy density in a novel electric vehicle battery - a step toward a more cost-effective, easily recycled battery that would allow EVs to travel farther and charge faster at a low cost.
Additive manufacturing offers an unprecedented level of design flexibility and expanded functionality, but the quality and process can drastically differ across production machines, according to Hui Yang, a professor of industrial engineering at Penn State. With applications in aerospace, health care and automotive industries with potential for mass customization, additive manufacturing needs quality management.
The German National Academy of Sciences Leopoldina and the German Council for Sustainable Development (RNE) have published a joint position paper presenting paths to climate neutrality by 2050. In it, the Leopoldina and the RNE highlight options for action to effect the changes needed within society, at political level and in the business world, in view especially of the urgency and the historic dimensions of the transformation we face.
Bacteria from an Indian landfill could help eliminate contaminated chemicals. The focus is on pesticides such as lindane or brominated flame retardants, which accumulate in nature and in food chains. Researchers at Empa and Eawag used these bacteria to generate enzymes that can break down these dangerous chemicals.
Osaka University researchers create an intelligent nanopore system sensitive enough to detect single SARS-CoV-2 virus particles. By training a machine-learning algorithm, the platform was able to identify between various coronaviruses in just five minutes. This work may lead to fast and accurate point-of-care testing for COVID and other communicable diseases.
Chemical engineers at the University of Illinois Chicago and UCLA have answered longstanding questions about the underlying processes that determine the life cycle of liquid foams. The breakthrough could help improve the commercial production and application of foams in a broad range of industries.
Current approaches for planning relocation for potentially millions of people affected by climate change are 'woefully inadequate' and risk worsening societal inequities, experts wrote in a policy perspective on June 17 in Science. Policymakers and scientists need to rethink how they work together to develop, communicate and carry out relocation plans so that relocating communities can thrive, though it relies on a transformation in how science is used, tools are deployed, and stakeholders are engaged.
Researchers have successfully used graphene -- one of the strongest, thinnest known materials -- to detect the SARS-CoV-2 virus in laboratory experiments.
