How liquid can a fluid be?
Microscopic spheres form strings in surprising alignments when suspended in a viscous fluid and sheared between two plates — a finding that will affect the way scientists think about the properties of such wide-ranging substances as shampoo and futuristic computer chips.
The new measurements, by UCLA physics professor Giovanni Zocchi and former UCLA physics graduate student Yong Wang, are approximately 100 times higher in resolution than previous mechanical measurements, a nanotechnology feat which reveals an isolated protein molecule, surprisingly, is neither a solid nor a liquid.
Model by model, the electronics in a car are being moved closer to the engine block. This is why the materials used for the electronics must resist increasing heat – so the glass solder being used as glue must be continually optimized.
Chemical engineer Ms Inês Mariz has presented guidelines for obtaining better quality and more efficient latex, in a PhD thesis defended at the University of the Basque Country (UPV/EHU).
In things thick and thin: Cornell physicists explain how fluids – such as paint or paste - behave by observing how micron-sized suspended particles dance in real time.
A liquid does not have to be a disordered bunch of particles: A team of researchers at Vienna University of Technology (TU Vienna) and the University of Vienna has discovered intriguing structures formed by tiny particles floating in liquids.
