Ionic liquids interesting in extracting molecules from wood
28-Oct-2015
Thanks to their unique properties, ionic liquids are all in the rage as solvents as "green" sustainable chemical processes. Recently, two research teams at Umeå University in Sweden discovered how enzymes can perform their catalytical processes in a switchable ionic liquid. The discovery paves ...
Unveiling distribution of defects in proton conductors
21-Oct-2015
Solid oxide fuel cells (SOFC), recently used as a power source for households in Japan, have several drawbacks such as high-cost, material degradation and long start-up time derived from high operating temperatures up to 750°C. Lowering the operating temperature to an "intermediate" range of ...
Giving atoms their marching orders
30-Jun-2015
Chemistry professor Linda Shimizu oversees a series of crowd-pleasing chemistry demonstrations in middle and high schools throughout central South Carolina every year. They are spirited affairs, and her research in the laboratory is just as dynamic -- but with a sense of order that really keeps ...
New technique for 'seeing' ions at work in a supercapacitor
24-Jun-2015
Researchers from the University of Cambridge, together with French collaborators based in Toulouse, have developed a new method to see inside battery-like devices known as supercapacitors at the atomic level. The new method could be used in order to optimise and improve the devices for real-world ...
Researchers Part Water
‘Electric Prism’ Separates Water’s Nuclear Spin States
10-Sep-2014
Using an "electric prism", scientists have found a new way of separating water molecules that differ only in their nuclear spin states and, under normal conditions, do not part ways. Since water is such a fundamental molecule in the universe, the recent study may impact a multitude of research ...
Food analysis and diagnostics are hot topics at analytica China 2014
08-Sep-2014
analytica China, International Trade Fair for Laboratory Technology, Analysis, Biotechnology and Diagnostics, opens its gates at the Shanghai New International Expo Centre (SNIEC) for the seventh time from September 24–26, 2014. This year's focus topics are food analysis and diagnostics. Among ...
Tracking Down Organic Fraudsters
05-Sep-2014
Organic food is booming – but was the much more expensive tomato really grown organically? This can be found out by means of an analytic technique that scientists from the university of Würzburg are working on. The demand for organic food is rising. It has almost tripled worldwide between 2002 ...
NMR under pressure: Reproducing deep-Earth chemistry
16-Jul-2014
A new pressure cell invented by UC Davis researchers makes it possible to simulate chemical reactions deep in the Earth's crust. The cell allows researchers to perform nuclear magnetic resonance (NMR) measurements on as little as 10 microliters of liquid at pressures up to 20 kiloBar. "NMR is our ...
Shock-absorbing 'goo' discovered in bone
26-Mar-2014
Latest research shows that the chemical citrate – a by-product of natural cell metabolism – is mixed with water to create a viscous fluid that is trapped between the nano-scale crystals that form our bones. This fluid allows enough movement, or 'slip', between these crystals so that bones are ...
Food safety at analytica 2014: Trace analysis for our health
04-Mar-2014
How safe is our food? This is a volatile issue for many consumers and a major challenge for the food-analysis sector. The only way to perform quality and origin analyses is with state-of-the-art equipment and techniques. That is why the topic of food analysis is an interdisciplinary focal point ...
