The Novosibirsk researchers have developed a device capable of producing mist with support from the Russian Foundation for Basic Research and the Foundation for Assistance to Small Innovative Enterprises (FASIE). The precise name of the device is “field device for measuring liquid and gas velocities”. It helps to perform prompt, precise and, most importantly, simultaneous measuring of the velocity at any point of the fluid and gas flow.
“Field device for measuring liquid and gas velocity” is the name of the device developed and produced by the researchers of Institute of Thermal Physics, Siberian Branch, Russian Academy of Sciences (Novosibirsk) with support from the Russian Foundation for Basic Research and the Foundation for Assistance to Small Innovative Enterprises (FASIE). The device helps to track in full detail the life of the flow and to learn, for example, what the velocity is at each point, how and where turbulences appear. In other words, it is possible not only to “shoot an animated film” about the flow of liquid or gas, but also to perform mathematical treatment of each “shot”.
The device operations are based on the principle known since the times of Prandtl and other classical hydrodynamics scholars. This is the so-called stroboscopical visualization of flows. In other words, small particles – tracers – are placed in the flow transparent for employed irradiation. The tracers do not influence the stream, they drift together with the flow, but the tracers are not transparent for irradiation.

Attoseconds break into atomic interior

A newly developed laser technology has enabled physicists in the Laboratory for Attosecond Physics (jointly run by LMU Munich and the Max Planck Institute of Quantum Optics) to generate attosecond bursts of high-energy photons of unprecedented intensity. This has made it possible to observe the interaction of multiple photons in a single such pulse with electrons in the inner orbital shell of an atom.
In order to observe the ultrafast electron motion in the inner shells of atoms with short light pulses, the pulses must not only be ultrashort, but very...
A group of researchers led by Andrea Cavalleri at the Max Planck Institute for Structure and Dynamics of Matter (MPSD) in Hamburg has demonstrated a new method enabling precise measurements of the interatomic forces that hold crystalline solids together. The paper Probing the Interatomic Potential of Solids by Strong-Field Nonlinear Phononics, published online in Nature, explains how a terahertz-frequency laser pulse can drive very large deformations of the crystal.
By measuring the highly unusual atomic trajectories under extreme electromagnetic transients, the MPSD group could reconstruct how rigid the atomic bonds are...

For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.
In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...
