A team of researchers has verified that it is possible to engineer two-layered nanofibers consisting of an ordered row of alternating peptides, and has also determined what makes these peptides automatically assemble into this pattern. The fundamental discovery raises the possibility of creating tailored "ABAB" peptide nanofibers with a variety of biomedical applications.
Scientists at The University of Tokyo studied a method for recycling unused concrete with wood fibers. They found the conditions that produce new building materials with bending strength even greater than the original concrete. This work may help reduce the CO2 emissions associated with manufacturing new concrete.
How can we anticipate and design out environmental impacts of new technologies when they are at an early stage of development? A new issue of Yale's Journal of Industrial Ecology presents cutting-edge research on the environmental assessment of emerging technologies.
Organic boronic acids are widely used as starting material in the synthesis of various useful chemicals. But, some organic boronic acids are unstable and lead to unwanted 'side reactions.' Thus, they need to be protected with a functional group, which needs to be removed afterwards. A research team from Tokyo University of Science recently uncovered how this unnecessary step (removal of the functional group) could be avoided--showing how to make this process much easier and cheaper.
Researchers at the University Of Liverpool, in collaboration with NUI Galway and TU Berlin, have identified the key technological and scientific challenges of producing hydrogen through seawater electrolysis.
Scientists from the Skoltech Center for Energy Science and Technology (CEST) and the Institute for Problems of Chemical Physics of Russian Academy of Sciences have developed a novel approach for preparing thin semiconductor fullerene films. The method enables fabrication of organic electronics without using toxic organic solvents and costly vacuum technologies, thus reducing the environmental risks and making organic electronics more accessible. The results of their study were published in the Journal of Materials Chemistry C.
Few studies have examined how the neighborhood's physical environment relates to cognition in older adults. Researchers categorized 4,716 individuals by apolipoprotein E (APOE) genotype -- a genetic risk factor for Alzheimer's disease (AD) to determine if there are cognitive benefits of living in neighborhoods with greater access to social, walking and retail destinations. Results showed that the positive influence of neighborhood environments on cognition are strongest among those who are at the lowest risk for AD, specifically APOE ε2 carriers.
Researchers from Osaka University have shown that the enantioselective organocatalyzed Rauhut-Currier and [3+2] annulation sequence in a microflow system can rapidly produce functionalized chiral spirooxindoles (up to 89% yield, 98% ee) within one minute. Although conventional methods for developing a flow synthesis procedure can be costly and labor-intensive, the researchers efficiently optimized multiple parameters by applying a machine learning algorithm. This unique approach may help realize novel synthetic routes in flow systems.
Researchers have demonstrated a new, green technology for both accelerated screening and retrieving 'switchable' solvents used in green chemistry applications. The new approach makes the screening process hundreds of times faster and drastically accelerates the rate at which solvents can be retrieved from solution.
UQ researchers have set a world record for the conversion of solar energy to electricity via the use of tiny nanoparticles called 'quantum dots'. The technology has a huge range of potential applications, including the possibility to use it as a flexible, transparent skin to power cars, planes, homes and wearable technology.
