A recent study shows the voids’ acceleration. Researchers used recent advances in ultrafast electron microscopy to measure voids in phonon-polariton waves zooming around inside a thin flake of boron nitride. Phonon-polaritons are quasiparticles formed from photons (quantized light) coupled with tiny vibrations, and they act like light and sound waves combined.

EXCERPT:
EU lawmakers and countries agreed to double tariffs on foreign steel on Monday, to shield the bloc’s struggling industry from a flood of cheap Chinese exports.
European Union governments and parliament representatives reached a late evening deal to hike levies on steel imports to 50 percent and slash the volume allowed in before tariffs apply by 47 percent.
“The shape and global standing of Europe‘s steel sector are fundamental to our strategic autonomy and industrial strength. We therefore cannot afford to turn a blind eye to global overcapacity reaching critical levels,” commented the EU’s trade chief, Maros Sefcovic.
“Today’s outcome helps bring much-needed stability for our producers to thrive in Europe”.
