Comparison of the luminescence properties of phosphate-tungsten bronze and cerium doped phosphate-tungsten bronze
(Kragujevac, Serbia : Institute for Information Technologies, University of Kragujevac, 2023)
Phosphate-tungsten bronzes (PWBs) constantly attract a lot of attention owing to their interesting chemical, mechanical, and optical properties. Furthermore, tungsten bronzes as inert inorganic solids, exhibit interesting ...
Optimization of the heterogeneously catalysed methanolysis of plum kernel oil in the presence of menthol-based deep eutectic solvent
(Leskovac : Faculty of Technology, 2023)
Waste plum kernels from the fruit processing industry might be a valuable oil source for biodiesel production which use can reduce the biodiesel production cost. The application of green cosolvents, like deep eutectic ...
Kinetic modeling of the biodiesel production from sunflower oil over corn cob ash
(Leskovac : Faculty of Technology, 2023)
The investigation of reaction kinetics is crucial for practical implications in process equipment design and scaling up. In this study, a kinetic analysis of the methanolysis of a blend of radish and castor oil catalyzed ...
The comparison of two methods used to observe a nonlinear system: potentiometry and holography
(Kragujevac, Serbia : Institute for Information Technologies, University of Kragujevac, 2023)
The transition from state I ( characterized by low iodide and iodine concentration) to state II (high iodide and iodine concentration) occurs in a nonlinear Briggs-Rauscher (BR) oscillatory reaction. This transition was ...
The investigation of chitin influence in laser induced deformation of butterfly wings
(Belgrade : Serbian Chemical SocietyBelgrade : Serbian Young Chemists’ Club, 2023)
The investigation of laser beam irradiation on different types of butterfly wings has been done previously by using the holographic method. The deformations due to the use of different laser wavelengths were observed. It ...
