  - THERMOCHIMICA ACTA - Year 2020

  This work focuses on the application of thermal analysis and kinetics investigations to analyze chemical processes during cross-linking of the complex fast-curing polyurethane system. Non-isothermal Differential Scanning Calorimetry (DSC) measurements were performed for both stoichiometric mixtures of polyol and isocyanate component and for mixture with large isocyanate excess. Isoconversional methods were used to calculate initial...

  Native starch was silicated by means of microwave-assisted reactions with varying doses of reagents. Resulting products were characterized by DSC and HMR-relaxation methods. It was observed that the hydratation of the silicated starches during gelatinization decreases when compared to that of the native potato starch. The amount of unfrozen water for ungelitinizated silicated starches are less than in control samples. At the same...

  - JOURNAL OF MOLECULAR LIQUIDS - Year 2022

  Thermal pyrolysis synthesized activated biochar from the Pinus elliottii sawdust (PS) at 600° C. The obtained activated biochar (PB600) was used for the removal of three diphenols, catechol (CAT), resorcinol (RES), and hydroquinone (HYD), which are utilized mainly in different industries. The PB600 was characterized by several analytical techniques. The BET surface area of 1473 m2.g−1 and a total pore volume of 0.707 cm3 g−1 was...

  W pracy przedstawiono metodę badania kinetyki reakcji otwarcia pierścienia á-laktamu, wykorzystującą technikę chromatografii gazowej. Na podstawie badań kinetyki reakcji w różnych temperaturach wyznaczono wartości energii aktywacji dwóch badanych reakcji. Podstawowym celem pracy było pokazanie możliwości wykorzystania GC w badaniach kinetyki reakcji prowadzonych w mikroskali.

  - Visnyk Lviv Univ. s.Physics - Year 2002

  Przeanalizowano zależność pomiędzy teoriami Simmonsa-Taylora oraz Rose´a, opisującą niestacjonarne procesy rekombinacji nośników nadmiernych, ich pułapkowania i uwalniania ze stanów zlokalizowanych. Równania Simmonsa-Taylora wyrażono w warunkach gęstości nośnika w stanach zlokalizowanych. Pokazano, że w pewnych przypadkach równania redukują się do równań Rose´a, odnoszących się do bimolekularnej lub monomolekularnej rekombinacji.
