PRECISION CALORIMETRIC RESEARCH OF MATERIALS, SUBSTANCES AND PROCESSES
PRECISION CALORIMETRIC RESEARCH OF MATERIALS, SUBSTANCES AND PROCESSES:
- Research (at the metrological level) of thermodynamic properties of promising substances and materials (dendrimers, fullerene-containing nanostructures, polyurethanes, biologically active substances (BAS), organoelemental compounds) and revealing fundamental relations between the composition and structure of objects and their thermodynamic properties, parameters of physical and chemical transformations and chemical reactions;
- Investigation of various features of biological processes (cultivation and anabiosis of microorganisms, denaturation of fibers, dehydration of biological and medical preparations, etc.);
- Investigation of thermodynamic characteristics of inorganic materials.
Main results:
- Precision measurements have been made of heat capacity, temperature and enthalpy of phase, relaxation and chemical transformations in the region of 6-670 K in nanostructures based on dendrimers with various end groups, fullerides and fullerene complexes with organoelemental ligands, graphite-like, diamond-like, carbine nanostructures and other objects. Their standard thermodynamic functions for the region from 0 to 350-670 К and standard thermodynamic characteristics of reactions to produce the objects under study and hypothetical reactions with their participation have been calculated. Computer data processing and electronic presentation has been performed in the form of reference and calculated values («Termopol» databank).
- The results obtained conform to international standards and have been included in the thermodynamic directory of the National Bureau of Standards of the USA and the best domestic directories and can be used for developing appropriate nanotechnologies and for other purposes.
- A series of studies has been performed to determine the limit of solubility of plasticizers in polymers and to construct the diagrams of states of polymer – plasticizer systems used in the development and optimization of production processes of biologically active substances and their extraction from natural raw materials.
- For the first time in the world, a polymer matrix has been designed for transdermal administration of medicines (beta-adrenergic blocking agents and hypoglycemic agent) to the patient’s organism. For the first time in the world, a method for diagnostics of malignant neoplasms according to the patient’s DTA blood data has been developed.
