How can a tin be opened if it contains not tinned goods but explosives? Or a shell or something no less dangerous, for instance, a retired nuclear reactor?
Certainly, metal can be cut up mechanically, but this is very dangerous. Torch flame or laser beam do not suit the purpose even more so. However, a sheet of water released at high pressure, particularly if additionally saturated with a stream of frozen drops, would probably suit. The researchers from the Tula State University are sure of that.
They suggest that morally and physically obsolete ammunition should be reclaimed in this particular way – the casing should be cut up and explosives should be washed out. In their opinion, this is the safest way, also from the ecological point of view, to separate metal from nitrocompounds - explosive and powder. Information about that is contained in the advanced research database maintained by the International Science and Technology Center.

Physicists of the University of Würzburg have made an astonishing discovery in a specific type of topological insulators. The effect is due to the structure of the materials used. The researchers have now published their work in the journal Science.
Topological insulators are currently the hot topic in physics according to the newspaper Neue Zürcher Zeitung. Only a few weeks ago, their importance was...
In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.
Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
