Their composition has been studied using inductively coupled plasma atomic emission spectroscopy (ICP-AES), CHNS-analysis, IR spectroscopy, powder X-ray diffraction (XRD), and X-ray photoelectron spectroscopy (XPS). The obtained nanoparticles were tested on chickens, and the best average daily increase in their weight was observed when feeding them with ferrous cysteinate nanoparticles in comparison with ferrous sulfate at a 10 times higher dosage.

Research paper thumbnail of Progress of computer potential of mankind as the basis for a new model of the universe

At present it is not possible to state what model is true among the suggested ones because all models are based on the assumptions a validity of which is scarcely determined. There are plenty of reasons, and the most important ones are impossibility of experiments performance on a global scale, very short time of nature study and low accuracy of determination of fundamental physical constants to check their possible drift. In the most of models the intellect is an unnecessary attribute. Mankind is only an inner insignificant observer in the Universe. Small changes which Humanity can produce on the Earth don't modify our planet on a global scale. However besides changes in the material world Mankind can create intellectual valuables. Large information content can be stored, integrate and process using computers. We have no any principle restrictions in advance of the computer engineering. Therefore we propose a new model of the Universe development which is based on the increasing facilities of our Mankind. In this model the Earth is considered as an analogue of supercomputer. Under certain circumstances Mankind is ready to carry out information processing for other civilizations, but such civilizations have not yet been found. The Creators of the Universe could be other customers. Computer-like model of the Universe suggests a communication with the Creators in future for execution of their calculation orders. However this model is not complete because of lack of high rate of information transfer for long distances.

Limitations connected with the absolute zero of temperature and the maximal velocity are considered, as well as the consequences of these limitations. A geometric approach is proposed as an alternative to the wave-particle duality to explain the anomalous motion of micro objects. The basis of the geometric approach is a comparison between two geometries differing from each other in the metric of infinitesimal. The interconnection of these geometries is possible through the direct and inverse Weierstrass transformation. The application of this transformation allows one to explain diffraction effects.

These possibilities are restricted to the framework of Euclidean space. No problems could arise during the development of the laws of classical science. However, it was established later on that in some areas it was rather difficult to describe the motion of the matter in terms of Euclidean models. In these cases, researchers either introduce a space of higher dimensionality, use complex numbers, or make some deformations of our habitual Euclidean space. Those were exactly the cases for which the pseudo-Euclidean, Hilbertian, reciprocal, micro-Euclidean and other spaces were proposed. Humans are able to think only in terms of Euclidean space. So, to provide a correct description of unusual motion of matter, the necessity arises to transform the information into the understandable Euclidean space. The operators suitable for these purposes are Lorentz transformations, Schrodinger equation, the integral transformations of Fourier and Weierstrass, etc. The features of information transformations between different spaces are illustrated with the examples from the areas of X-ray structural analysis and quantum physics.

Research paper thumbnail of New Polymorphic Modification of Y, Ho, Tm and Lu tris-2,2,6,6-tetramethyl-heptane-2,4-dionates: Structure, Volatility and Luminescence

SSRN Electronic Journal, 2020

The crystal structure of new isostructural complex Y(thd) 3 ( I ), Ho(thd) 3 ( II ), Tm(thd) 3 ( ... more The crystal structure of new isostructural complex Y(thd) 3 ( I ), Ho(thd) 3 ( II ), Tm(thd) 3 ( III ) and Lu(thd) 3 ( IV ) are determined: space group Pna 2 1 , Z = 8 ( a = 41.956(8) A, b = 17.837(4) A, с = 9.742(2) A, V = 7291(3) A 3 for I ; a = 41.778(2) A, b = 17.8045(6) A, с = 9.6862(3) A, V = 7204.9(4) A 3 for II ; a = 41.884(5) A, b = 17.758(2) A, с = 9.672(1) A, V = 7193.7(2) A 3 for III, a = 41.942(8) A, b = 17.712(4) A, с = 9.711(2) A, V = 7214(2) A 3 for IV ). The crystal structures of I – IV are molecular and consist of discrete monomeric Ln(thd) 3 molecules (Ln = Y, Ho, Tm, Lu). The highest quantum yields of luminescence are obtained for Tb(dpm) 3 (77%), [Tb(thd) 3 ] 2 (25%) and Dy(thd) 3 (5%), [Dy(thd) 3 ] 2 (0.4%). Thermogravimetric investigations show that the volatility of complexes increases from Yb(thd) 3 to Pr(thd) 3 . Melting points of the complexes are close to the known literature data. The complex compounds we synthesized were characterized by NMR in a CDCl 3 solution. Quantum chemical calculations are shown that for the Y(III) complexes with thd-ligands the phase of dimeric molecules is energetically more stable.

The difficulties and philosophical problems of this area of science are discussed. Discussions of many great scientists who paved the foundations of the physics of micro-world are described. These discussions are still urgent. The diversity of interpretations of the wave function, light interference, uncertainty principle, complementarity and completeness of micro-world description are stressed in this book. Difficulties and problems of quantum mechanics described in this book allowed the author of the present communication to propose a new approach based on the infinitely small metrics The difference of infinitesimals in two geometries allows one to explain W. Heisenberg's uncertainty principle. Interconnection of the images in these geometries is possible with the help of Weierstrass integral transform. This approach allows one to describe the interference of light behind the screen with slits as a sum of the corpuscular component (Weierstrass transform) and the wave component (Fourier transform).
