impurity concentrations . The value of the effective ion charge, Zeff, can be varied, by pulsing controlled amounts of impurity gases into the hydrogen plasma. NUCLEAR FUSION 15 (1975) CONTROL OF RE-CYCLING ...
solubility (in particular Pr 3+ ions ) and its dependence on OH- ion concentrations in GeS2 glasses Influence of vapor-phase reaction on the reduction of OH and S–H absorption bands in GeS -based glasses ...
Abstract Thirteen unknown impurities and isomers in cefminox sodium were separated and characterized by liquid chromatography coupled with high-resolution ion trap/time-of-flight mass spectrometry ...
prepared with adjustment by initial substrate concentration . Process-related impurities profiling HPLC-MS/MS analysis was performed as described earlier [3]. Impact II QqTOF high-resolution mass-spectrometer ...
, the best time of the GNR and SOD combination reaction is 50 min. In strategy 2, we studied the effect of inorganic salt ion concentration on fluorescence intensity . When the concentration of Na+ was 0.1–0.2 ...
membrane to designated cellular enzymes such as superoxide dismutase and cytochrome c oxidase.7–9 The chaperone system allows the free copper ion concentrations in the cell to be maintained at an absolute ...
the protonation and the adsorbent’s surface charge, in addition to the species of Cr(VI) in the mix. The absorption of Cr(VI) as a consequence of hydrogen ion intensity was investigated throughout a pH range of 1–9 ...
, the concentration of impurities , and the mobility of ions [36]. The lowest value of EC was 137μS/cm in Tukure and the highest value was 285μS/cm in Setumari. The moderate value of EC in water may be due to domestic ...
) [50]. The peaks at +0.70 and +0.35 V can be attributed to the reduction of NO3− ions (from HNO3) to NO and NO2 respectively (Eqs ix and x) [51]. Such gaseous species (NO and NO2) can create extra forces ...
