,M?ssbauer and X-Ray Diffraction Investigations of a Series of B-Doped Ferrihydrites,ely models for its attachment. Particle sizes were in the 2–4 nm range, and as borate sorption increased, the ferrihydrite particle size decreased. The .-spacings of two-line ferrihydrite increased with increased borate adsorption. Isomer shift and quadrupole splitting exhibit slight increasing tren

Study of Malayaite and Malayaite Cobalt Pigment, thermic process. In this work, the synthesis of Malayaite and the structure of a Malayaite-based pigment, Sn/Co pink, is investigated by X-ray diffraction and Mossbauer spectroscopy. The results indicate Malayaite and Cassiterite formation, but the ion cobalt incorporated in the Malayaite structure

,Synthesis of Calcium Telluride as a Possible M?ssbauer Source, both samples correspond to the orthorhombic tricalcic telluride. Once the two samples of calcium telluride were identified, they were irradiated with thermal neutrons in a Nuclear Reactor. The results of both samples of iodine correspond to the 27.72 keV photo peak of .I reported in 1962. The calci

On the Rust Products Formed on Weathering and Carbon Steels Exposed to Chloride in Dry-Wet Cyclicalined by means of different techniques. Special emphasis is given to the methodology of analysis of the data using 300 K and 77 K M?ssbauer spectrometry and X-ray diffraction. The rust that is loosely bound to the metal surface and that it is lost during the corrosion process, for both types of steel

,Ferrimagnetic to Paramagnetic Transition in Magnetite: M?ssbauer , Monte Carlo,es of magnetite as well as the corresponding average field were followed as a function of temperature in order to elucidate the critical behavior of magnetite at around the Curie temperature. Results evidence a progressive collapse of the M?ssbauer spectra onto a singlet-type line at a critical temp

,M?ssbauer Investigation of Fe-Mn-Cu Nanostructured Alloys Obtained by Ball Milling,nd ac-susceptibility. Results indicate that the Cu addition favors the formation of a FCC phase with two different magnetic states at room temperature, i.e., an antiferromagnetic and a paramagnetic one. Thermal evolution of the M?ssbauer spectra revealed the occurrence of a magnetic ordering along a
