Sr1.50Ca1.50Fe2.25Mo0.75O9– and Sr1.92Ca1.08Fe2.04W0.96O9– double perovskites are synthesized in the polycrystalline form by a solid-state reaction route in air and studied at room temperature using the of PXRD, Raman and Mössbauer... more
Zinc plant residue (ZPR) is a secondary material generated during hydrometallurgical zinc production that contains considerable contents of valuable elements such as Zn, Cu, Fe, Pb, Cd, Ag, In, Ga, Tl. Zinc, copper and accompanying... more
A series of Ni x Zn 1 À x Fe 2 O 4 (x ¼ 0.5, 0.6 and 0.7) ferrite nanoparticles have been synthesized using a co-precipitation technique, in order to understand the doping effect of nickel on their structural and magnetic properties. XRD... more
An attempt has been made to prepare nanocrystalline nickel substituted lithium ferrites, having chemical composition Li 0.5 À 0.5x Ni x Fe 2.5 À 0.5x O 4 (where x ¼0.0–1.0 with a step increment of 0.2) by a citrate-gel auto combustion... more
Occupation of Fe in ZnO structure X-ray diffraction Mössbauer spectroscopy UV-Vis diffuse reflectance spectroscopy A B S T R A C T A series of Fe-doped ZnO (Zn 1-x Fe x O, x = 0, 0.01, 0.03, 0.05, 0.07 and 0.10) samples were synthesized... more
Single phase MFeCrO 4 (M = Co/Ni) nanosized samples are prepared by solution combustion method using glycine as fuel. Lattice parameter obtained after Rietveld refinement of the powder x-ray diffraction pattern of CoCrFeO 4 and NiCrFeO 4... more
We argue in favor of the physical basis of YARK theory of gravity and show that the major part of recent criticism by Corda (Corda, C. Symmetry 2018, 10, 558-559) is based on either irrelevant or erroneous claims. We highlight a perfect... more
Phase transformation in cement during hydration is studied by XRD, FTIR and Mössbauer. The hydration process was monitored by self consistent analysis of the XRD results. Alite and belite phases control the early setting time of cement.... more
The structural and magnetic properties of lithium ferrite nanoparticles synthesized through the solution combustion route at different fuel to oxidizer ratio are studied using different techniques. Powder X-ray diffraction studies show... more
This chapter provides an overview of results obtained by a variety of spectroscopic techniques. The most common techniques employed are infrared and Raman spectroscopy, which enable detailed observation of in particular the behaviour of... more
In the present paper, the adsorption of amino acids (Ala, Met, Gln, Cys, Asp, Lys, His) on clays (bentonite, kaolinite) was studied at different pH (3.00, 6.00, 8.00). The amino acids were dissolved in seawater, which contains the major... more
Keywords: Evolved and slightly evolved glauconite Condensed section Rim and core of glauconite pellet Mössbauer spectroscopy of glauconite Reverse glauconitization Vermiforms A detailed mineral chemical investigation of glauconite within... more
Haltern 70 amphora sherds from Castro do Vieito and from kilns in the Roman provinces Baetica and Lusitania were studied by Mössbauer spectroscopy, EDX and XRD. An amphora whose handle was carefully studied must have been fired reducingly... more
In hyper-alkaline aqueous solutions, the three-legged stool-like [Sn(OH)3]− is the only hydroxido complex with a very short (2.078 Å) Sn–O distance.
In this paper, we re-analyze the ingenious experiment by Kündig (measurement of the transverse Doppler shift by means of the Mössbauer effect) and show that a correct processing of experimental data gives a relative energy shift E/E of... more
The Eastern Rhodopes are the main area of distribution of various in color and genesis jaspers in Bulgaria. With the help of Mössbauer spectroscopy and Electron Paramagnetic Resonance (EPR) spectroscopy, the iron status and distribution... more
Why is space 3-dimensional? After a brief review of the modern approaches to this query, emphasizing those papers which touched upon epistemological problems, it is stressed that there are two questions which deserve special attention.... more
Magnetic properties of the Mott insulator with the pyrochlore structure Y2Ru2O7 were investigated using Ru99 Mössbauer spectroscopy. Bulk magnetization measurements confirmed appearance of the spin-glass-like antiferromagnetic order with... more
