AB  - Recently there is an effort to reach highly reversible and stable materials for energy storage 
processes. Novel materials used in electrochemistry-based energy storage as a suitable 
supports for noble ones, has been predominant in the past few years. Supercapacitors, as a 
bridge between batteries and traditional capacitors, have attracted significant attention as new 
promising energy storage devices. Hybrid nanomaterials based on manganese, cobalt, and 
lanthanum oxides of different morphology and phase compositions were prepared using a 
facile single-step ultrasonic spray pyrolysis (USP) process. Transition metal oxides are 
considered as an ideal electrode materials for electrochemical redox transitions-based
pseudocapacitors, because they can provide a variety of oxidation states for rather fast and 
efficient redox transitions. Strontium-doped lanthanum cobaltites (La1-xSrxCoO3- , LSCO)
have shown promising catalytic performance for ORR in alkaline media. The aim of this 
investigation was to bring detailed insights of supercapacitive potentials of pure LSCO and 
LSCO hydrothermally doped by RuO2. Also, to separate influences of constituting oxides to 
this issue, in order to reveal the redox electrochemistry behind perovskite structures as
supports for supercapacitive applications.

AB  - Hybrid nanomaterials based on manganese, cobalt, and lanthanum oxides of different morphology and phase compositions were prepared using a facile single-step ultrasonic spray pyrolysis (USP) process and tested as electrocatalysts for oxygen reduction reaction (ORR). The structural and morphological characterizations were completed by XRD and SEM-EDS. Electrochemical performance was characterized by cyclic voltammetry and linear sweep voltammetry in a rotating disk electrode assembly. All synthesized materials were found electrocatalytically active for ORR in alkaline media. Two different manganese oxide states were incorporated into a Co3O4 matrix, δ-MnO2 at 500 and 600◦C and manganese (II,III) oxide-Mn3O4 at 800◦C. The difference in crystalline structure revealed flower-like nanosheets for birnessite-MnO2 and well-defined spherical nanoparticles for material based on Mn3O4. Electrochemical responses indicate that the ORR mechanism follows a preceding step of MnO2 reduction to MnOOH. The calculated number of electrons exchanged for the hybrid materials demonstrate a four-electron oxygen reduction pathway and high electrocatalytic activity towards ORR. The comparison of molar catalytic activities points out the importance of the composition and that the synergy of Co and Mn is superior to Co3O4/La2O3 and pristine Mn oxide. The results reveal that synthesized hybrid materials are promising electrocatalysts for ORR.

AB  - The main objective of this research was a systematic development of advanced micro/nanostructured materials based on the most used metal-oxides for ORR and metal-oxides with an extremely low-loading of Pt for comparison. Hybrid composites compared were: MnO2, La2O3, mixed lanthanum manganese oxides (LMO), and mixed lanthanum manganese oxides with reduced platinum load (LMO-Pt). The influence of the reduced amount of noble metal, as well as single oxide activity toward ORR, was analyzed. The complete electrochemical performance of the hybrid materials has been performed by means of CV, LSV, and EIS. It was shown that all synthesized catalytic materials were ORR-active with noticeable reduction currents in O2 saturated 0.1 M KOH. The ORR behavior indicated that the La2O3 electrode has a different mechanism than the other tested electrode materials (MnO2, LMO, and LMO-Pt). The EIS results have revealed that the ORR reaction is of a mixed character, being electrochemically and diffusion controlled. Even more, diffusion is of mixed character due to transport of O2 molecules and the chemical reaction of oxygen reduction. O2 diffusion was shown to be the dominant process for MnO2, LMO, and LMO-Pt electrolytic materials, while chemical reaction is the dominant process for La2O3 electrolytic materials.

AB  - The main objective of this research is the development of catalytic materials based on a combination 
of metal-oxides with extremely low-loading of Pt for oxygen reduction reactions (ORR). Materials 
compared were La2O3 with 5 mass% loading of Pt (La2O3-Pt) and La2O3/MnO2 multioxide based 
material with 5 mass% loading of Pt (LMO-Pt). The electrochemical characterization of the catalytic 
materials has been done using cyclic voltametry (CV), linear sweap voltammetry (LSV) and 
galvanostatic electrochemical impedanse spectroscopy (GEIS). It was proven that both synthesized 
catalytic materials were ORR-active. The ORR behavior indicated that La2O3-Pt electrode is 
significantly less active than LMO-Pt. The GEIS results showed that the ORR is complex 
electrochemical reaction, being electrochemically and diffusion controlled. Diffusion is of mixed 
character due to transport of O2 molecule and chemical reaction of oxygen reduction reaction. O2
diffusion is the dominant process for LMO-Pt catalytic materials, while chemical reaction is

AB  - Electroenzymatic processes are interesting solutions for the development of new processes based on renewable feedstocks, renewable energies, and green catalysts. High-selectivity and sustainability of these processes are usually assumed. In this contribution, these two aspects were studied in more detail. In a membrane-less electroenzymatic reactor, 97% product selectivity at 80% glucose conversion to gluconic acid was determined. With the help of nuclear magnetic resonance spectroscopy, two main side products were identified. The yields of D-arabinose and formic acid can be controlled by the flow rate and the electroenzymatic reactor mode of operation (fuel cell or ion-pumping). The possible pathways for the side product formation have been discussed. The electroenzymatic cathode was found to be responsible for a decrease in selectivity. The choice of the enzymatic catalyst on the cathode side led to 100% selectivity of gluconic acid at somewhat reduced conversion. Furthermore, sustainability of the electroenzymatic process is estimated based on several sustainability indicators. Although some indicators (like Space Time Yield) are favorable for electroenzymatic process, the E-factor of electroenzymatic process has to improve significantly in order to compete with the fermentation process. This can be achieved by an increase of a cycle time and/or enzyme utilization which is currently low.

abstract = "Electroenzymatic processes are interesting solutions for the development of new processes based on renewable feedstocks, renewable energies, and green catalysts. High-selectivity and sustainability of these processes are usually assumed. In this contribution, these two aspects were studied in more detail. In a membrane-less electroenzymatic reactor, 97% product selectivity at 80% glucose conversion to gluconic acid was determined. With the help of nuclear magnetic resonance spectroscopy, two main side products were identified. The yields of D-arabinose and formic acid can be controlled by the flow rate and the electroenzymatic reactor mode of operation (fuel cell or ion-pumping). The possible pathways for the side product formation have been discussed. The electroenzymatic cathode was found to be responsible for a decrease in selectivity.

AB  - Low cost and highly active electrocatalysts for the oxygen reduction reaction (ORR) are necessary for the development of fuel cells and metal air batteries. Currently, Pt based electrodes have the best catalytic performance but due to is high cost its employment on a significant scale is limmited. Perovskite materials would be a good alternative because of is abundant supply, envronmental benignity, electronic structure, ionic conductivity and redox behavior. Therefore, the aim of this work is synthesis and characterzation of Lanthanum cobalt oxide (LaCoO3) powders doped with Manganese (Mn) - LMCO or Strontium (Sr) - LSCO, as promissing candidates for energy storage and conversion devices. Ultrasonic spray pyrolisis (USP) was used to successfully synthsize spherical sub-microm-m-szed of Lai0.6Sr0.4CoO3 and La0.6Mn0.4CoO3 perovskite type materials. Detailed microscopic analysis (SEM-EDX, TEM, XRD) as well as electrochemical characterization by CV, LSV and EIS technique has been conducted.

AB  - Perovskite have emerged as promising materials in newly invented energy storage and conversion devices due to their exceptional thermal stability, electronic structure, ionic conductivity, electron mobility, and redox behaviour [1]. Among perovskite that are suitable as catalyst for electrode in supercapacitors and solid oxide fuel cells, lanthanum strontium cobalt oxides have shown promising catalytic activity and relatively high stability [1]. Also, Co-based lanthanum manganite (LMCO) has been used as cathode material with a high electro-chemical catalytic activity for oxygen reduction[2].Ultrasonic spray pyrolysis (USP) was used to successfully synthesize spherical sub-µm-sized of La0.6Sr0.4CoO3 (LSCO) and Mn and Sr-doped LaCoO3 powders. LSCO should be of wider voltage window than carbonaceous materials, with the possibility to adopt the pseudocapacitive oxide, such as RuO2, not only by simple surface adsorption, but over full or partial incorporation into the oxide structure. Hence, this work aims to investigate supercapacitive potentials of pure LSCO prepared by single step USP and LSCO doped with RuO2. The catalytic activity of Sr and Mn cation substitution in lanthanum cobalt oxide was also investigated. Electrochemical behaviour was investigated by EIS, CV and LSV techniques. The EIS and CV analyses showed that RuO2 catalyzes the redox transition of Co species, with simultaneous proportional increase in pseudocapacitive abilities of RuO2 itself while being hosted by LSCO. The investigated LMCO electrodes by CV and LSV techniques showed excellent catalytic activity for oxygen reduction. Our work indicated that these perovskite shows potential applications in the field of pseudocapacitance electrode materials and is worthy of further investigation.

AB  - Considerable promotion of A’ substituted AA’BO3 perovskite-like structure of rare earth–CoO3 composite supercapacitive performances is reported. The influence of cation substitution in perovskite structure on supercapacitance was also investigated. Spherical, sub-µm-sized, regular spheres of La0.6Sr0.4CoO3 (LSCO) and LaCoO3 (LCO) were synthesized by ultrasonic spray pyrolysis under different temperatures. The synthesis of Co-based oxide, namely La0.6Sr0.4CoO3 (LSCO), was performed within single-step USP procedure. As starting precursors aqueous solutions with 0.10 M concentration of La(NO3)3·6H2O (99.9% rare earth oxide), Sr(NO3)2 (99 %) and Co(NO3)2 (98%) were used for the synthesis of LSCO, and aqueous solutions with 0.10 M concentration of La(NO3)3·6H2O (99.9% rare earth oxide) and Co(NO3)2 (98%) were used for synthesis of LCO. The solution for the LSCO and LCO synthesis were prepared by mixing starting precursor solutions in stoichiometric mole ratios. Synthesis temperatures were adjusted and kept to 600°C and 800°C. LSCO and LCO composites were investigated for their supercapacitive performances in alkaline solution. Microstructure and surface morphology were studied by Scanning Electron Microscopy and X-ray Diffraction measurements. Electrochemical characterization of all LCO and LSCO samples included cyclic voltammetry (CV), galvanostatic charge-discharge (G C/DC) and electrochemical impedance spectroscopy (EIS). The registered capacitance for LSCO reveals the promoting influence of Sr on A’ position in perovskite on capacitance. The EIS analysis showed that Sr catalyzes the redox transition of Co species, with simultaneous proportional increase in capacitive abilities. This intrinsic interactive promotion introduces LSCO composite as unique supercapacitive material. Synthesis temperature plays important role on supercapacitive performances.

AB  - Energy is the main driver of economic growth and it is of vital significance for the modern socieity survival. Future economic growth is dependent of the long-term availability of energy from the sustainable and ecologicaly accepted sources. Microbial fuel cell (MFC) is a new approach to the wastewater treatment with the simulntanious energy production. MFC is an electrochemical device that uses bacteria to generate electricity from biodegradation of organic substrates. Bacteria obtain the energy required for metabolism by electron transfer from an electron donor, such as glucose or acetate, to an electron acceptor, such as oxygen. The application of a microbial fuel cell for the treatment of wastewater has many advantages: the process is clean, safe noise-free, the emissions are low, and the efficiency is high with direct energy production. The subject of this review paper is a detailed development of microbial fuel cells, working principle, types of used microorganisms, as well as potential application.

The percentage of decolorization of Reactive black 5 dye is given as a function of absorbance vs exposure time of dye solutions to the different oxidation systems. The optimal conditions for the given systems were also examined in order to make the degradation more efficient.",

AB  - Ubrzan stepen reprodukcije cijanobakterija poznat je pod nazivom “cvetanje vode” prilikom čega dolazi do produkcije toksičnih
sekundarnih metabolita cijanobakterija – cijanotoksina a koje može biti opasno kada izazove negativne posledice u vodenom ekosistemu,
kao što su mortalitet živog sveta usled nedostatka kiseonika, poremećaj stabilnosti ekosistema, negativan uticaj na lance
ishrane. Cijanotoksini spadaju u grupu raznovrsnih jedinjenja kako po hemijskoj strukturi, tako i po dejstvu na ljude i životinje i
izazivaju ozbiljna oštećenja kao što su hepatoenteritis, simptomatska pneumonija i dermatitis nakon upotrebe ili kontakta sa vodom
koja je zagađena. Cvetanje cijanobakterija je registrovano u svim delovima sveta, od severa Norveške i Finske do Australije.
Premda postoji zdravstveni rizik usled izlaganja cijanotoksinima u Republici Srbiji ne postoji legislativa sa graničnim vrednostima za
različite načine izlaganja ljudi cijanotoksinima u cilju prevencije potencijalnog zdravstvenog rizika. Stoga je predmet i cilj ovog rada
pregledni prikaz cvetanja cijanobakterija na teritoriji Srbije u vodenim ekosistemima u poslednjih 130 godina, kao i karakterizacija
cijanotoksina, metode njihove detekcije i metode uklanjanja.
