Preservation of arthropod cuticles is of paramount importance for taphonomic interpretations in which the fossil record of the chitin-protein complex is considered a key molecular signature of the group studied. In this ...

Vanadium oxide thin films were fabricated using a multi-step deposition process involving magnetron sputtering and sequential annealing. The structural, vibrational, and nanomechanical properties of the films were invest...

The rechargeable lithium air (oxygen) battery (Li-O2) has very high energy density comparable to fossil fuels (∽3,600 Wh/kg). However, the parasitic reactions of the O2- reduction products with solvent and electrolyte ...

Ferrochelatases catalyze the insertion of ferrous iron into the porphyrin during the heme b biosynthesis pathway, which is fundamental for both prokaryotes and eukaryotes. Interestingly, in the active site of ferrochelat...

In this paper, the adsorption of trivalent chromium cations by a sample of sodium-modified TiO2 was studied. XRF analysis of the TiO2 surface was performed.  The dependence of the adsorption value on the duration of the...
