AB  - In the past two decades spinel ferrites nanoparticles have been extensively investigated due to their potential applications in a variety of fields (data storage, catalysis, energy, environment, biomedicine, etc.). In the present work, zinc ferrite nanoparticles with different copper content (Zn(1-x)CuxFe2O4; x=0, 0.2, 0.4, 0.6, and 0.8) but with the same particle size distribution and amount of oleic acid as capping agent were prepared by solvothermal synthesis and the physicochemical properties of as-prepared samples were investigated. The prepared samples were characterized by X-ray powder diffraction (XRD), transmission electron microscopy (TEM), Fourier transform infrared spectroscopy (FT-IR) and vibrating sample magnetometry (VSM). The XRD results show that all the diffraction maxima correspond to the cubic spinel structure, while TEM images reviled that samples are consisted of sphere-like particles, 5-7 nm in size. The presence of oleic acid on the surface of nanoparticles was confirmed by FTIR analysis. The magnetic measurements revealed superparamagnetic behavior of obtained powders, with gradual increase of saturation magnetization.

AB  - In this study, solvothermally synthesized nanoparticles of cobalt ferrite (CoFe2O4, CFO) and Zn/Ga-dopped cobalt ferrite (Co0.5Zn0.5Fe2O4, CFO_Zn and CoFe1.5Ga0.5O4, CFO_Ga, respectively) with dihydrocaffeic acid (DHCA) as a surfactant were examined for electrochemical detection of gallic acid. Based on X-ray diffraction analysis, diffraction maxima of all samples correspond to the cubic spinel phase, while transmission electron microscopy showed that the nanoparticles are non-agglomerated, sphere-like with an average size of 5±1 nm. The presence of DHCA on the surface of nanoparticles was confirmed by Fourier Transform Infrared Spectroscopy (FTIR). For the purpose of electrochemical detection of gallic acid the modified glassy carbon electrode (m-GCE) was prepared from CFO, CFO_Zn and CFO_Ga nanoparticles. Initial tests have shown instability/disintegration of m-GCE in aqueous solutions, because of which samples were annealed at 450 °C in air. Cyclic voltammograms of all annealed samples showed good reversibility in the system [Fe(CN)6] 3-/4- . The most efficient electron transfer was achieved when the mass ratio between sample and Nafion® was 85:15, respectively. The best sensitivity to gallic acid (10-4 M, in Britton-Robinson buffer) was observed for CFO_Zn sample. Results are showing that by selective functionalization and surface modification of nanoparticles, it is possible to optimize the electrochemical properties suitable for sensing, which is the basis of this method and the goal of further research.

AB  - Epitaxy represents a process of crystal growth or material deposition in which the new created layers have a high degree of crystallographic alignment with the substrate lattice. In this research 10 nm-thick thin films of strontium titanate (STO) were grown using pulsed laser deposition (PLD) method on Si(001) whose surface was either deoxidized with strontium oxide (SrO) or buffered by reduced graphene oxide (rGO) in combination with SrO deoxidation. In addition to differently prepared Si(001) surface, the effect of deposition temperature on the crystalline structure of the STO thin films was also examined. Reflection high energy electron diffraction (RHEED), atomic force microscopy (AFM), X-ray diffraction (XRD), X-ray reflectivity (XRR) and X-ray photoelectron spectroscopy (XPS) methods were used to examine the properties of the grown films. It was concluded that the STO thin film grown on the rGO-coated Si substrate at 515 °C shows the highest crystallinity with a smooth surface, while the film deposited on the bare silicon has amorphous structure. The STO films grown at 700 °C show textured or polycrystalline structure. Good crystallinity, epitaxial alignment, and clean interface are the major requirements for STO/Si and the STO/rGO/Si heterostructure for making an efficient and stable Si photocathode for the photoelectrochemical (PEC) water splitting. Our future work will be directed toward understanding how the obtained interfaces and crystalline structure of STO films are influencing the PEC process.

AB  - Epitaxial films of metal oxides deposited on silicon substrates represent a new type of material that could be used as protective (or electroactive) layer in the photoelectrochemical water splitting. To understand the influence of crystalline and interfacial properties of oxide layer on the water splitting process a ~10 nm strontium titanate (STO) films have been grown using the PLD method on bare and reduced graphene oxide (rGO) buffered silicon substrate. Our approach relied on the oxide-silicon integration using combination of SrO-assisted deoxidation and controllable coverage of silicon surface with a mono- to threelayer of spin-coated GO. The STO films have been grown at 515 and 700 °C and various experimental techniques were used to examine the surface and crystalline properties of grown films (reflection high energy electron diffraction, atomic force microscopy, scanning electron microscopy, X-ray diffraction, X-ray reflectivity and X-ray photoelectron spectroscopy). The results show that the best the crystallinity of the STO thin films was obtained on rGO/SrO deoxidized silicon surface at 515 °C. Future studies will be devoted to electrochemical characterization of the grown films, that will help to establish clearer link on how the interface and crystalline parameters affect the water splitting process.

AB  - Epitaxy represents a type of crystal growth or material deposition in which new crystalline layers are formed with one or more well-defined crystallographic orientations with respect to the seed layer. The epitaxy is usually implemented in the cases when new functionality is to be integrated with the already present platform. The two methods for the epitaxial growth of thin films i.e. pulsed laser deposition (PLD) and ion beam assisted deposition (IBAD) will be compared. We will highlight the most important aspects of the epitaxial growth of metal oxides (MO) on semiconductor (SC) substrates, including processes in the vapor phase and at the MO/SC interface. We will describe how the growth parameters (temperature, partial pressure, deposition rate, etc.) can affect the stoichiometry, morphology and overall crystalline structure and properties of the MO thin film. The important properties of MO and MO/SC interface will be also highlighted from the point of view of photoelectrochemical water splitting. Beside the growth parameters, the role of ion beam irradiation in tuning of physical and chemical properties of the MO and SC will be also discussed. The selection of appropriate characterization methods (surface and bulk) will be also highlighted for monitoring the growth of MO and the processes relevant in photoelectrochemical water splitting. An outline of the first experiments to be performed will be also presented.

abstract = "Epitaxy represents a type of crystal growth or material deposition in which new crystalline layers are formed with one or more well-defined crystallographic orientations with respect to the seed layer. The epitaxy is usually implemented in the cases when new functionality is to be integrated with the already present platform. The two methods for the epitaxial growth of thin films i.e. pulsed laser deposition (PLD) and ion beam assisted deposition (IBAD) will be compared. We will highlight the most important aspects of the epitaxial growth of metal oxides (MO) on semiconductor (SC) substrates, including processes in the vapor phase and at the MO/SC interface. We will describe how the growth parameters (temperature, partial pressure, deposition rate, etc.) can affect the stoichiometry, morphology and overall crystalline structure and properties of the MO thin film. The important properties of MO and MO/SC interface will be also highlighted from the point of view of photoelectrochemical water splitting. Beside the growth parameters, the role of ion beam irradiation in tuning of physical and chemical properties of the MO and SC will be also discussed. The selection of appropriate characterization methods (surface and bulk) will be also highlighted for monitoring the growth of MO and the processes relevant in photoelectrochemical water splitting.
