Evaluation of the Properties of Wood-Polymer Composites by Microtomography DOI: 10.22184/2227-572X.2020.10.2.110.114
The results of evaluating the properties of wood-polymer composites (WPC) are presented. As objects of study were selected commercially available WPC based on different polymers. To analyze the structure of WPC using computer microtomography – one of enough new non-destructive methods for the study of the bulk structure of composites using X rays. To assess the overall durability and behavior of finished products in actual use tests were carried out in special devices artificial weather (weatherometer).

Standardless X ray Spectral Analysis: Reality or Myth? DOI: 10.22184/2227-572X.2020.10.2.124.130
The article is based on the material of the author’s plenary report at the III All-Russian Conference on Analytical Spectroscopy. The reason for its writing was the fact that the author, in the process of reviewing many scientific papers, came across completely unacceptable results of electron probe microanalysis (EPMA) obtained with modern instruments. Today, a significant part of electron microscopes is equipped with energy dispersive X ray spectrometers (EDS) with appropriate mathematical software. As a result of this, an additional opportunity arises – conducting a EPMA the studied object. The manuals for using these spectrometers offer a fairly simple and fast analysis algorithm, usually without any reference samples (RS). This approach is called standardless analysis (SA). The development of SA and the problem of correct definitions are discussed.

Grand-MP – Atomic Emission Spectrometry With Microwave Plasma DOI: 10.22184/2227-572X.2020.10.2.140.146
Atomic emission spectrometry with microwave plasma (MP-AES) is an attractive method for the elemental analysis of solutions, because it allows the use of nitrogen produced by a generator from air as a working gas. Changing the analyte excitation conditions by varying the parameters of the plasma excitation source has become a necessary set of options for modern optical spectrometers when developing new or adapting existing analysis methods. The use of microwave plasma of the toroidal shape of the Grand-MP spectrometer, stable over a wide range of operating parameters, made it possible to significantly improve the characteristics of the MP-AES method.
New Educational Paradigm of Practical-Oriented Teaching of History of Chemistry at the Universities: Experience of the Chemistry Department of Lomonosov Moscow State University DOI: 10.22184/2227-572X.2020.10.2.162.171
On December 10, 2019, the Second Student Scientific -Practical Conference On the History of Chemical Instrumentation and Chemical-Technological Processes, organized jointly by the Chemistry Department of Moscow State University and the supervisors of the Polytechnic Museum was held in the building of Open Collections of Polytechnic Museum.
