Laccase Polyphenolic Biosensor Supported on MnO2@GNP Decorated SPCE: Preparation, Characterization, and Analytical Application
(The Electrochemical Society ("ECS")., 2021)
Based on graphene nanoplatelets capability to build block composites, as well as well-known electrochemical characteristic of the manganese oxide materials, in the present research, a nanocomposite, formed from graphene ...
Studies of the regioselective ring-opening closing mode of functionally different thiazolidine type enaminones: en route to the synthesis of trithiaazapentalene derivatives
(Oxford : Pergamon-Elsevier Science Ltd, 2013)
Trithiaazapentalene derivatives were prepared by the reaction of 2-alkylidene-4-oxothiazolidines with Lawesson's reagent. They are classified as two structurally different trithiaazapentalene compounds that have different ...
Assessment of the ecological status of large lowland rivers (Sava and Tisa, Serbia) based on digital microscopic investigation of the diatom communities
(Taylor & Francis, 2024)
Large lowland rivers represent an important type of ecosystem that has been under a constant anthropogenic influence (industry, thermal
power plants, untreated communal water, and agriculture) for centuries, which has led ...
Characterization and methanol electrooxidation studies of Pt(111)/Os surfaces prepared by spontaneous deposition
(American Chemical Society (ACS), 2006)
Catalytic activity of the Pt(111)/Os surface toward methanol electrooxidation was optimized by exploring a wide range of Os coverage. Various methods of surface analyses were used, including electroanalytical, STM, and XPS ...
Assessment of heavy metal pollutants accumulation in the Tisza river sediments
(Academic Press Ltd- Elsevier Science Ltd, London, 2009)
In this study we have worked on the evaluation of heavy metal contamination in the sediments taken from the Tisza River and its tributaries, and thereby used the sequential extraction method, geochemical normalization, the ...
Mechanical features of copper coatings electrodeposited by the pulsating current (PC) regime on Si(111) substrate
(Electrochemical Science Group (ESG), 2020)
Mechanical features of the Cu coatings produced by the pulsating current (PC) regime on Si(111)
substrate have been investigated. The Cu coatings were electrodeposited by varying duty cycle (15−50 %) and keeping the current ...
Density Functional Theory Study of the Multimode Jahn-Teller Effect - Ground State Distortion of Benzene Cation
(Springer, Dordrecht, 2012)
The multideterminental-DFT approach performed to analyze Jahn-Teller (JT) active molecules is described. Extension of this method for the analysis of the adiabatic potential energy surfaces and the multimode JT effect is ...
Periodic Operation with Modulation of Inlet Concentration and Flow Rate Part I: Nonisothermal Continuous Stirred-Tank Reactor
(Wiley, 2016)
The nonlinear frequency response (NFR) method, which is an analytical, fast, and easy method for evaluating the performance of forced periodically operated chemical reactors, was used to investigate possible improvements ...
Kerogen structural studies-oxidations with alkaline permanganate and with ferric chloride
(Elsevier, 1980)
Two oxidizing agents were used for structural studies of the kerogen from Aleksinac shale (Yugoslavia), namely: (1) alkaline potassium permanganate, and (2) acidic ferric chloride. (1) The main goal with alkaline permanganate ...
Morphology, structure and hardness of electrolytically produced copper coatings
(Sarajevo : Faculty of Science University of Sarajevo, 2022)
Influence of various parameters of electrodeposition, such as type of cathode, composition of the electrolyte and thickness of the coating, on morphology, structure and hardness of copper coatings has been investigated.
