Electrochemical and solid state science transcend the limits of academic science to touch many of the things we come into contact with on a day-to-day basis, whether we know it or not. Most recently we’ve gotten a first-hand account of this at our Electrochemical Energy and Water Summit, where some of the brightest minds in electrochemical and solid state science came together to solve critical issues in global sanitation. Now, these sciences are even assisting in the preservation of culture.

Pin-sized painting samples from Vincent van Gogh’s “Sunflowers” painting have been extracted from the Van Gogh Museum and are now under the microscope at The University of Queensland’s Centre for Microscopy and Microanalysis (CMM).

UQ’s Professor John Drennan is leading the project, which aims to understand the aging characteristics of significant artworks in order to improve conservation techniques.

While breath analysis is most commonly known for its ability to detect alcohol consumption, it has the potential to extend far beyond that use. Breath analysis has the ability to diagnose a wide range of human conditions, and is now being utilized to aid the bottlenose dolphin.

Engineers from the University of California, Davis have developed a device for collecting dolphin breath for analysis. Because invasive techniques such as skin biopsies and blood sampling are difficult to perform on wild dolphins, this device will make it easier to check the health of the marine animals, study their biology, and aid in wildlife conservation.

This from UC Davis:

The researchers designed an insulated tube that traps breath exhaled from a dolphin’s blowhole and freezes it. They analyzed samples to create profiles of the mix of metabolites in breath, established baseline profiles of healthy animals and were able to identify changes in the breath of animals affected by disease or other factors. The researchers concluded that breath analysis could be used to diagnose and monitor problems in marine mammals – and, by extension, in ocean health as well.
