Thermodynamic test of Li2WO4 single crystals with low molybdenum doping: Enthalpy, interconnections, heat capacity

The thermodynamic test of Li2WO4 single crystals doping by low molybdenum content with special emphasis on investigation of interconnections, enthalpy, heat capacity to improve device portfolio was performed. We reduced doping content in 7 times for Li2W1-xMoxO4 in this investigation. The formation enthalpy of Li2WO4 was estimated using interconnections. The heat capacity was measured for Li2W1-0.025Mo0.025O4 single crystal (T = 320–997 K) by differential scanning calorimetry. There were no phase transitions of Li2W1-0.025Mo0.025O4 single crystal that made single crystals with low doping by molybdenum promising for application. The single crystal of lithium tungstate doped by 1.25% molybdenum (content was Li2W0.9875Mo0.0125O4) was grown by LTG CZ for the first time. The reaction enthalpies of Li2W0.9875Mo0.0125O4 single crystal were investigated by reaction calorimetry. The interconnections of formation enthalpies and lattice enthalpies of Li2W1-xMoxO4 in the range (x = 1–0.0125) from x were established. It indicated the growth of phenakite structure in the range. It was shown that under conditions of low temperature gradients it was possible to grow perfect single crystals of lithium tungstate with low doping of molybdenum.

Adjusting the Organization-Managerial Sphere in Conditions of New Scientific and Technological Revolution

Setting-up and functioning of state, regional and city bases and banks of data required serious transformation of the whole information sphere. It is necessary to regulate, structure and unify the pattern and content of the principle types of documents and data being collected, to arrange procedures of formation and actualization of data, coordinate the interaction of key data storages. The topicality of the research subject can be explained by the transition stage in scientific and technological development and complicated process of public acceptance of modern drastic innovation. Investigation of interconnection between technical and social progress takes root in works by K. Marx, F. Engels, J. Schumpeter, G. M. Keince. The goal of the research is to study development and perfection of organization-managerial sphere at the stage of new scientific and technological revolution. The author on the basis of collection and summarizing (synthesis), systematization (systematic method) and comparative analysis (complex and comparative and analytical methods) of materials obtained from official information resource and other sources of information analyzes the following aspects of management: organization-structural, functional, informationtechnological and methodological.

Main directions in modern research of interaction between climate and land use/land cover changes

The purpose of the research is to analyse and assess existing approaches in investigation of interconnections between climate and underlying surface. Land use/land cover (LULC) influences climate formation via physical and chemical properties (albedo, roughness, height, chemical composition etc.). Climate in its turn affects land cover by means of meteorological parameters (air temperature and humidity, precipitation, wind etc.) and causes both cyclic and irreversible changes in land cover. In addition, anthropogenic factors exacerbate surface-climate interactions through? for example, LULC change that usually causes an additional release of chemical compounds. The paper distinguishes three main directions of the “climate - LULC” interactions research that is conducted mainly with application of satellite monitoring products, observation dataset, geographic information systems (GIS) and numerical modelling. The first direction implies monitoring and research of cyclic changes and transformation of LULC influenced by natural and anthropogenic factors, using different GIS-based satellite and surface meteorological observation databases. Despite significant technical progress and great amount of studies conducted for detecting dynamics of LULC change for different time intervals, the problems of dealing with cloudiness and shadows from orographic and other objects still remain. The second direction investigates the influence of LULC change on the chemical composition in the atmospheric boundary layer and on the regional climate. Numerous researches were dedicated to the influence of different kinds of surface such as forests, grasslands, croplands, urban areas etc. on climate characteristics and also on fluxes, for example, CO2. The effect of midlatitude forests on climate remains to be one of the challenging and urgent issues. The third direction relates to LULC change modelling and regional climate modelling. For the last decade a spatial resolution of models was considerably increased and, as a result, representation of interaction between atmosphere and land improved. Online integrated numerical atmospheric models are found as the most promising ones. They include "meteorological parameters – atmospheric chemical composition" feedbacks and can consider LULC on global and regional scales. However, some issues still need improvement, namely radiative transfer, cloud microphysics, cloud-aerosol-precipitation interactions, as well as parametrizations of some types of land and their interaction with the atmospheric boundary layer.
