Converting carbon dioxide to carbon monoxide using water, electricity — ScienceDaily

Researchers at the University of Illinois at Chicago and the Joint Center for Artificial Photosynthesis have determined how electrocatalysts can convert carbon dioxide to carbon monoxide using water and electricity. The discovery can lead to the development of efficient electrocatalysts for large scale production of synthesis gas — a mixture of carbon monoxide and hydrogen. “The electrochemical reduction of carbon dioxide to fuels is a subject of considerable interest because it offers a means for storing electricity from energy sources…

Museum collections track soot in the atmosphere throughout the 20th century — ScienceDaily

Horned Larks are cute little songbirds with white bellies and yellow chins — at least, now they are. A hundred years ago, at the height of urban smoke pollution in the US, their pale feathers were stained dark gray by the soot in the atmosphere. A new paper in the Proceedings of the National Academy of Sciences shows that the discoloration of birds in museum collections can be used to trace the amount of black carbon in the air over…

Detecting impurities on 3-D components

The fluorescence scanner – an imaging, inline measuring system – inspects components for impurities during the manufacturing process and identifies the exact point of contamination. Credit: © Photo Fraunhofer IPM Impurities adhering to the surface of components can cause problems in later stages of the production process – or even make the entire component useless. A new fluorescence scanner developed by the Fraunhofer Institute for Physical Measurement Techniques IPM allows specialists to inspect metallic parts for residues of grease, machining…

Near-Earth asteroid CubeSat goes full sail — ScienceDaily

NASA’s Near-Earth Asteroid Scout, a small satellite the size of a shoebox, designed to study asteroids close to Earth, performed a full-scale solar sail deployment test at ManTech NeXolve’s facility in Huntsville, Alabama, Sept. 13. The test was performed in an indoor clean room to ensure the deployment mechanism’s functionality after recent environmental testing. NEA Scout is a six-unit CubeSat that relies on an innovative solar sail for propulsion. It is one of 13 secondary science payloads NASA selected to…

New technique spots warning signs of extreme events

Credit: CC0 Public Domain Many extreme events—from a rogue wave that rises up from calm waters, to an instability inside a gas turbine, to the sudden extinction of a previously hardy wildlife species—seem to occur without warning. It’s often impossible to predict when such bursts of instability will strike, particularly in systems with a complex and ever-changing mix of players and pieces. Now engineers at MIT have devised a framework for identifying key patterns that precede an extreme event. The…

Chemists report breakthrough in material design

Scientists from Utah State University, USA and Southern Federal University, Russia, computationally designed a new, metastable, ultra-light crystalline form of aluminum. Credit: Iliya Getmanskii, Southern Federal University, Russia If you drop an aluminum spoon in a sink full of water, the spoon will sink to the bottom. That’s because aluminum, in its conventional form, is denser than water says Utah State University chemist Alexander Boldyrev. But if you restructure the common household…

New self-powered paper patch could help diabetics measure glucose during exercise

A new paper-based sensor patch developed by researchers at Binghamton University, State University of New York could allow diabetics to effectively measure glucose levels during exercise. Credit: Binghamton University Electrical and Computer Science Assistant Professor Seokheun Choi A new paper-based sensor patch developed by researchers at Binghamton University, State University of New York could allow diabetics to effectively measure glucose levels during exercise. Today’s most widespread methods for glucose self-testing involve monitoring glucose levels in blood. Conventional measurements, however, are…

NASA air traffic management research tool shows new colors

A pivotal piece of NASA air traffic management (ATM) software is getting fresh attention as the agency and its government, industry and academic partners prepare to test new ideas for more efficiently guiding aircraft through the nation’s skies. The software is called FACET – short for Future Air Traffic Management Concepts Evaluation Tool – and it was such a hit when it was introduced a decade ago that NASA named it the agency’s Software of the Year for 2006. …

Next-generation transport

Understanding the physics of cavitation — in this case the formation of bubbles in liquid — will help oceangoing vessels of the future become more energy efficient. Credit: University of California – Santa Barbara For most of us, fluid dynamics and mechanics aren’t particularly significant—that is, until we’re white-knuckling it on a bumpy plane ride or trying to stay buoyant in unusually bubbly water. The way we navigate through air and water may one day be improved thanks to UC…

Nexon – ‘The SUV’ from Tata : Meet, Drive & Car Experience

Tata’s new compact SUV Nexon is soon to be launched and we witnessed its unveiling in God’s own country, Kerela. It’s been a week since we were a part of the fantabulous road trip and we are still in awe of the revving of the engines on curvy roads and celestial landscape. We were humbled by the hospitality on this two-day event. On the first day, we were briefed about Nexon by Tata’s leadership, at Kochi Marriot. The rendezvous with…
