Nanotechnologies to prevent explosion in fuel tanks

-
The Austrian company Hirtenberger Prosafe Safety Technology GmbH uses the Bayer MaterialScience AG multi-wall carbon nanotubes i.e. Baytubes™ for an innovative safety technology that significantly reduces the risk of explosions in fuel tanks. In fact this Austrian company has developed innovative hollow spheres which have been designed to prevent the formation of explosive gas mixtures in fuel tanks. These carbon nanotube filled-spheres that will be soon introduced on the global market under the trade name Safeball™ are treated with anti-fungal and anti-bacterial agents. They are an interesting alternative to extruded metal mesh or plastic foam usually used for this purpose. They have to be introduced into fuel tank in order to completely fill it, the available tank volume being only reduced by 8.5% due to their special shape that allows fuel to flow freely while preventing any dangerous surging, which occurs when large volumes of liquid are displaced.

Today's KNOWLEDGE Share:PLA BOTTLE

Today's KNOWLEDGE Share Ever wondered how we can reduce plastic pollution in India? The Mysuru-based Defence Food Research Laboratory (DFRL), affiliated with the DRDO, has launched an eco-friendly remedy with the introduction of biodegradable water bottles. Crafted from sustainable Polylactic acid (PLA) material, these bottles not only combat plastic waste but also contribute to reducing the overall carbon footprint. The best thing about this bottle is its all-encompassing sustainability approach – the bottle, cap, and label are all compostable. This innovation, derived from 100% bio-based and renewable sources, sets us on a path towards environmental conservation and fosters a greener and more sustainable future.

Today's KNOWLEDGE Share:High and low shear rate changes in Rheology

-

Today's KNOWLEDGE Share If a relatively high Mw grade flows from thin to thick, as shown in the picture, and if the time needed to fill the thick section is way shorter than the average polymer relaxation time, the polymer will not be able to reach its higher viscosity (corresponding to higher thickness/lower shear-rate). I am assuming here the polymer reached equilibrium low viscosity in the thin section, say for instance because it is much longer. Any pressure prediction not accounting for transient rheology would then overpredict the pressure to fill.Of course the diverging flow will further complicate the situation and mess with the molecular orientation created in the thin section, but to what extent ? Since this is more of a reasonable "conjecture", don't take this for granted, and discuss or share your opinion in the comments. There are hundreds of Rheology papers on the "4:1 contraction flow". Not sure I have ever seen any on the..."1:4 expansio
