Mass spectrometry (MS), a hundred-year-old subject, has been a technique of profound importance to molecular science. Its impact in solid-state materials science has not been evident, although many materials of modern science, such as fullerenes, have their origins in MS. Of late, mass spectr...
Populus euphratica is a salt tolerant and Populus × canescens a salt sensitive poplar species. Because of low transcriptional responsiveness of P. euphratica to salinity we hypothesized that this species exhibits an innate activation of stress protectiv
Mass spectrometry was the most commonly employed technique for the identification of bioactive compounds (81.5%) wherein one study used ESI-MS/MS, one used LC–QToF–MS, one used GC-MS, and two used NMR spectroscopy. Secondly, liquid chromatography was used for the identification of bioactive ...
pudica leaves with the help of the proton-induced X-ray emission (PIXE) technique. PIXE analysis revealed that trace elements of Fe = 308.467 mg/L, Mn = 65.664 mg/L, Zn =18.209 mg/L, Cu = 10.707 mg/L, Co = 2.025 mg/L, and V= 0.059 mg/L were present in M. pudica leaves. ...
