Inversion of electrical mobility measurements using bipolar or unipolar chargers for the arbitrary distribution of channels

引用

Particuology 2015年第3期13卷 114-123页

作者： m.Domat F.E.kruis N.L.Azong-Wara J.m.Fernandez-Diaz Department of Physics University of OviedoC/Calvo Sotelos/nE-33007 OviedoSpain Institute of Technology for Nanostructures(NST) and Center for Nanointegration Duisburg-Essen(CENIDE) University of Duisburg-EssenBismarckstr.81D-47057 DuisburgGermany

The inversion of the particle size distribution from electrical mobility measurements is analyzed. Three different methods are adapted for a dot-matrix approach to the problem, especially for non-square or singular matrices, and applied to electrical mobility measurements from fixed or scanning voltages. mul- tiply charged particles, diffusion losses, arbitrary voltage steps and noise were considered, which results in non-adjoining and overlapping transfer functions. The individual contribution of the transfer func- tions in each size interval was geometrically estimated, which requires only its characteristic mobilities. The methodology is applied to mobility measurements from particles charged with unipolar and bipolar chargers. However, the method can be extrapolated to any charging method with a defined charge distribution, and retrieval of the singly charged particle distribution and mean charge from a tandem differential mobility analysis configuration was successfully demonstrated.

Kinetics of the gas phase reaction of SnO with O2

Kinetics of the gas phase reaction of SnO with O2

引用

The 24th International Symposium on Shock Waves

作者： J.Herzler m.Kennedy F.E.kruis P.Roth Institut fur Verbrennung und Gasdynamik Prozeβ-und Aerosolmeβtechnik Universitat Duisburg-Essen 47048 Duisburg Germany

The gas phase reaction of SnOg with O2 was studied behind reflected shock waves at temperatures between 1700 and 2300 K and pressures around 100 kPa by applying atomic resonance absorption spectroscopy for time-resolved measurements of O atoms at 130.6 nm. The source of gas phase SnOg were SnO nanoparticles which rapidly evaporate behind the reflected shock wave in a few microseconds. For the reaction SnOg + O2 →SnO2,g + O a rate coefficient of k1 = 1014.78±0.19 ×exp(-23530±840K/T)cm3mol-1s-1 was determined for the temperature range of the present experiments.

AIm:To study the efficacy, safety, and feasibility of a granulocyte adsorptive type apheresis system for the treatment of patients with chronically active ulcerative colitis despite standard ***: An open label multicenter study was carried out in 39 patients with active ulcerative colitis (CAI6-8) despite continuous use of steroids (a minimum total dose of 400 mg prednisone within the last 4 wk).Patients received a total of five aphereses using a granulocyte adsorptive technique (Adacolumn(R), Otsuka Pharmaceutical Europe, UK). Assessments at wk 6 and during follow-up until 4 mo comprised clinical (CAI) and endoscopic (EI) activity index, histology, quality of life(IBDQ), and laboratory ***: Thirty-five out of thirty-nine patients were qualified for intent-to-treat analysis. After the apheresis treatment at wk 6, 13/35 (37.1%) patients achieved clinical remission and 10/35 (28.6%) patients had endoscopic remission (CAI＜4, EI＜4). Quality of life (IBDQ) increased significantly (24 points, P＜0.01)at wk 6. Apheresis could be performed in all but one patient. Aphereses were well tolerated, only one patient experienced ***: In patients with steroid refractory ulcerative colitis, five aphereses with a granulocyte/monocyte depleting filter show potential short-term efficacy. Tolerability and technical feasibility of the procedure are excellent.
