The Adsorption of SDS on Ferro-Precipitates
The main aim of the paper is to evaluate ferroprecipitates as immobilization agents for removing selected surfactants from aqueous solutions. Two ferro-precipitates based on iron oxides were used. Adsorbents were varied both in elementary composition and mineral composition. Sodium dodecyl sulphate (SDS) was used as a model anionic surfactant. Simultaneous measurements of the surfactant’s adsor...
متن کاملSurface States on Tungsten
There have been sevex'al recent theoreti. cal papers predicting that surface states can exist in d-band metals near the cx'ossover of s and d bands of the same symmetry. ' ' This paper reports the first direct experimental evidence of surface states on clean single-crystal faces of tungsten. Total energy di.stributions of field emitted electrons from single-crystal planes reveal surface-depende...
متن کاملApplications of Ferro-Nanofluid on a Micro-Transformer
An on-chip transformer with a ferrofluid magnetic core has been developed and tested. The transformer consists of solenoid-type coil and a magnetic core of ferrofluid, with the former fabricated by MEMS technology and the latter by a chemical co-precipitation method. The performance of the MEMS transformer with a ferrofluid magnetic core was measured and simulated with frequencies ranging from ...
متن کاملOn the Temperature Dependence of Ferro-Magnetic Saturation.
1 C. Spearman, Abilities of Man, Their Nature and Measurement, Macmillan, 1927; see Appendix, p. viii. 2 H. T. H. Piaggio, Brit. J. Psychol., 24, 88-105 (1933) states the matter clearly (p. 104) when in discussing Kelley's tests he says: "However, in deciding what tests to retain we make the tetrad relations the criterion, and not preconceived notions about dissimilarity of tests; indeed in the...
متن کاملSurface ferro (or antiferro) magnetism in bulk antiferro (or ferro) magnets : renormalization group analysis
2014 The renormalization group techniques are applied, for the first time, to surface magnetism in bulk magnets, for all signs of surface and bulk coupling constants. The q-state Potts model is specifically focused upon, and an interesting q-evolution of the phase diagram is exhibited. In particular the Ising model (q = 2) presents a remarkable feature in the case of competing bulk-and surface ...
