Determination of the Fermi surface and field-induced quasiparticle tunneling around the Dirac nodal loop in ZrSiS

Unambiguous and complete determination of the Fermi surface is a primary step in understanding the electronic properties of topical metals and semimetals, but only in a relatively few cases has this perdieme lingerie goal been realized.In this work, we present a systematic high-field quantum oscillation study up to 35 T on ZrSiS, a textbook example

Czech medicinal plants as possible sources of antioxidants

The antioxidant activity of 17 Czech medicinal plants was studied and compared with the antioxidant activity of green tea.The antioxidant activities of water and ethanol extracts of the plants tested were determined by a spectrophotometric method using the stable free radical DPPH (2,2-diphenyl-1-picrylhydrazyl), and further the contents of the com
