The physiological role of titanium in plants has not been elucidated yet , but a higher rate of growth , greater chlorophyll content and higher productivity, among others , may be attributed to this element. We have investigated the distribution of titanium in wheat seedlings after Titavit (a Ti · ascorbate containing plant conditioner) treatment applied(More)
For the on-line speciation of selenocystine (SeCys), selenomethionine (SeMet), selenoethionine (SeEt), selenite (Se(IV)) and selenate (Se(VI)), a high-performance liquid chromatography-UV irradiation-hydride generation-atomic fluorescence spectro- metric method is described. Separation was carried out on a conventional reversed-phase C18 column modified(More)

Thermal nebulization of nickel-base alloys, corundum plates and residues of solutions was performed with a laser beam. The solid aerosol was aspirated into an acetylene-air flame by an ejector. Linear analytical curves in wide concentration ranges were established and an average relative standard deviation of 10% was found. The detection limit is in the ng(More)
We present a time-resolved optical technique to measure electron spin dynamics with GHz dynamical bandwidth, transform-limited spectral selectivity, and phase-sensitive (lock-in) detection. Use of a continuous-wave (CW) laser and fast optical bridge enables greatly improved signal-to-noise characteristics compared to traditional optical sampling(More)
