The Laboratory was founded in April 2014 on the basis of group of desorption mass spectrometry of biomolecules and biopolymers. Laboratory staff is 5 co-workers including 3 PhDs. The Laboratory researchers have published more than 60 original papers and 3 PhD theses were defended.

 

Research directions

• Identifying an opportunities of application of temperature desorption mass spectrometry (TPD MS) to solve a problems of surface chemistry and catalysis.

• Investigating a processes of heterogeneous catalytic pyrolysis of renewable biomass components for a development of green technologies of synthesis of oleochemicals and biofuel.

• Search of structure-reactivity correlations on a surface of dispersed oxides.

• Adsorption and determination of a structure of an adsorption layer of biologically active compounds and biopolymers on a surface of nanosized materials.

• Development of biocompatible composites based on silica, polysaccharides and bioactive molecules (anesthetics, hemostatics, antiseptics, etc.) as potential systems of prolonged or transdermal release of drugs.

 

Main results

Regularities and characteristics of the kinetics of thermal transformations of a wide range of organic molecules (aliphatic carboxylic acids, aliphatic amines, phenolic acids, anesthetics) and biomolecules (coumarins, flavonoids, muramildipeptides, carbohydrates, polysaccharides) have been determined in a solid state and on a surface. The analytical software and instrument base for TPD MS investigations in the laboratory currently have no analogues in Ukraine.

Methodological approach for obtaining the correlations of structure - reactivity of organic molecules on the surface of fine materials and catalysts has been developed using the TPD MS data. The kinetic parameters have been calculated, the reaction parameter has been defined, the mechanisms of reactions of ketenes and alkenes from chemisorbed complexes of carboxylic acids and aliphatic amines on silica surface have been proposed.

Thermolysis stages have been identified, kinetic parameters have been calculated and scheme of thermal transformations of aglycone, peptide fragment and carbohydrate residue of O-glycoside muramyl dipeptide have been proposed.

It is the first time, using TPD MS data of polysaccharides for medical assignment, the method for determining the part of the polymer segments directly linked with surface, known as the parameter p, has been developed. This parameter is the main physico-chemical characteristics of the polymer adsorption. The informational content of pressure of volatile products - pyrolysis temperature curves (P/t) has been shown to control the quality and purity of biopolymers. It is the first time the method of determining the degree of deacetylation of chitin and chitosan using TPD MS data has been proposed. It has practical implication for their standardization.

The investigations in the laboratory are conducted in collaboration with scientists of the Institute of the NAS of Ukraine, universities (Ukraine, Hungary, Korea, Sweden), within the international grants “Pyrolysis with the use of nanocatalysts MexOy/SiO2 ‑ the way to get second-generation biofuels via processing of fatty acids, triglycerides and renewable plant biomass” (CRDF Global, USA), "Mass-selected Ion Deposition and Surface Characterization Techniques for Evaluation of Nanocatalytic Conversion of Biomass Components in Biofuels Production” (EMSL, USA), “Development of green nanotechnologies for catalytic pyrolysis of biomass” (Sweden).
