We have studied the internal microstructure of the ceramic samples. It was established that on the surface and within the bulk interior of all the samples, there are micropores of sizes ranging from a few micrometers to tens of micrometers and microcracks as long as several hundred microme...

The chemical composition of talc is Mg3[Si4O10](OH)2, and the crystal belongs to the layered silicate mineral of triclinic system.Pseudo-hexagonal single crystals are rare, and they are usually dense massive, bladelike, fibrous or radial aggregates.White or various light colors, streaks...
Two residue samples of this black material were subject to molecular characterization in order to assess first its composition and then the function of this precious object. Two different technique analyses, namely gas chromatography–mass spectrometry (GC–MS) and electrospray ionization Fourier ...

Chemical composition sensor. A novel approach to seam tracking is the use of a component of the arc spectrum to detect the presence of particular chemical species. [250] The arc emission is collected by a fibre optic and passed to an on-line analysis device, which monitors the level of the...
