Collisions and compositional variability in chondrule-forming events [PDF]

Geochimica et Cosmochimica Acta, 296:18-37 (2021), 2021
Compound chondrules, i.e. chondrules fused together, make a powerful probe of the density and compositional diversity in chondrule-forming environments, but their abundance among the dominating porphyritic textures may have been drastically underestimated.

Nanohybrids of a MXene and transition metal dichalcogenide for selective detection of volatile organic compounds

Nature Communications, 2020
Two-dimensional transition metal carbides/nitrides, known as MXenes, have been recently receiving attention for gas sensing. However, studies on hybridization of MXenes and 2D transition metal dichalcogenides as gas-sensing materials are relatively rare ...

Volatile compounds present in traditional meat products (charqui and longaniza sausage) in Chile

Brazilian Archives of Biology and Technology, 2012
The aim of this work was to identify and quantify the volatile compounds in five different commercial brands of charqui and longaniza sausages. Volatile compounds were extracted from some samples headspace using solid phase microextraction (SPME).
