Magnetic Studies of Fine Fe And Co Species Formed in Fe/Zeolite Catalysts
Magnetic, Mössbauer, and I.R. studies of nanosize particles of Fe and Co species dispersed in a cage of aluminosilicates structure, in relation to syngas (CO+H2) Fischer Tropsch conversion. The difference in the catalytic activity of such species have shown dependancy on their degree of dispersion. The carbonyl impregnation gave ultra-fine Super Paramagnetic Fe3O4, whereas the nitrate impregnat...
متن کاملExperimental Study on TGA, XRD and SEM Analysis of Concrete with Ultra-fine Slag (TECHNICAL NOTE)
The performances of cementitious materials as well as the efficiency of construction are adversely affected at high temperatures. Previous studies have already demonstrated that ultra-fine (alccofine) material accelerates the hydration of cement particles and subsequently improves the mechanical and durability properties of the concrete at normal temperature. Moreover, at higher temperatures th...
متن کاملA successful pregnancy following SEM fine tuning of hormonal priming
BACKGROUND: Manipulation of the uterine epithelium utilising standard dose exogenous oestrogen (E2) and progesterone (P4) has been shown to achieve a mature secretory morphological response. However, in an in vitro fertilisation (IVF) setting, frozen embryo transfer (ET) has had a low success rate. We propose that in patients with previously failed ET attempts, the uterine epithelium can be dir...
متن کاملFE-SEM Evaluation of Dental Specimens Prepared by Different Methods for In Vitro Contamination
Objective. To evaluate through FE-SEM the cleanliness and dentinal alterations promoted by different methods of dental sample preparation. Methods. Twenty-five human single-rooted teeth were used. The teeth were cleaned and autoclaved in wet medium and randomly divided into 5 groups (n = 5), according to the preparation methods employed-control group: no solutions applied; group 1: cement remov...
متن کاملNanoscale Crystallographic Analysis in FE-SEM Using Transmission Kikuchi Diffraction
Recent developments in SEM column design have led to the ability to produce nm spot sizes even at high probe currents [1], thus pushing the analytical techniques available in the SEM to conduct microanalysis with nanometer resolution. Although the limitations of microanalysis at these spatial resolution requirements stem from the physics of beam-specimen interaction and the volume from which th...
