In part, this favourable result can be attributed to the low energy of rare gas atom ejection (0.1 eV). The experimental data suggest that the angular distributions of ejected rare gas atoms are strongly forward peaked. Presumably for this reason the yields of GPG ions observed with an ...
XPS investigation of simple metals The x-ray photoemission spectra of the valence band region of Be, Na, Mg, and Al have been measured and are analysed in terms of existing band structures. ... H. Hchst,P Steiner,S Hüfner - 《Zeitschrift Für Physik B Condensed Matter》 被引量: 130...
The combination of a cation and anion exchange membrane produces a third type of membrane known as a bipolar ion exchange membrane [3]. IEMs are used for mass separation, chemical synthesis, energy conversion, and storage processes [4]. The most commonly known applications are chloroalkali ...
To solve the question regarding the correct order of properties indicated in brackets, we will analyze each option step by step.Step 1: Analyze Dipole Moments of NH3, NF3, and BF3 1. NH3 (Ammonia): - Struct
Rydberg gas theory of a glow discharge plasma: III. Formation, occupied state distributions, free energy, and kinetic control. The gas can exist in a deep free energy well (> 120 kJ mol(-1) below ionisation level when 10(10) < or = N(R) < or = 10(11) atoms cm(......
We present the photoionisation modelling of the intrinsic absorber in the bright quasar HS 1603 + 3820. We constructed the broad-band spectral energy distribution using the optical/UV/X-ray observations from different instruments as inputs for the photoionisation calculations. The spectra from the ...

The sign of collision energy (CE) and declustering potential (DP) indicates the polarity of ionisation. Product ions are [M1H] and 2 [M2H] , respectively in all cases. b 1 or – instead of concentration signifies the presence of unknown metabolite concentration or the absence of the res...
M.H. Gschwend et al. / J. Chromatogr. B 831 (2006) 132–139 133 After a single oral dose of 50 mg racemic amisulpride, the drug shows a rapid absorption with an absolute bioavailabil- ity of about 50% and a biphasic absorption profile [3–5]. Two distinct plasma concentration pe...
