Abstract: The 1H Nuclear Magnetic Resonance Relaxometry has been used for studying properties of various porous materials. T1 and T2 relaxation times in such systems are influenced by the molecule confinement and T1/T2 ratio can reflect an interaction strength between an adsorbate molecules and an adsorbent surface.

Abstract: In this work, we present fabrication and electrochemical characterization of bilayer doped diamond electrodes. The bilayers with different doping concentration have been fabricated by plasma enhanced chemical vapor deposition in two steps: namely an inner thick layer of highly boron doped diamond ([B] > 2∙1020 B atoms per cm-3) and an outer thin layer with a lower boron concentration.

Abstract: Basing on the quantum transport formalizm a formula for the irreversible transfer of charged particles has been introduced by us recently. This formula is expected to be suitable for the theoretical description of the electron or hole transfer between quantum dots, other nanoparticles, molecules, and so on. [..] Read more

Abstract: Nanodiamond particles (NDs) have recently risen in popularity owing to their unique and perspective properties. Merging NDs with organic molecules, such as polypyrrole (PPy), into hybrid organic-semiconductor functional systems gives rise to potential applications in photovoltaics (PV), which is supported by prior experimentally observed charge transfer between bulk diamond and PPy.

Abstract: We study formation and properties of graphene grown on diamond films with a prospect for large area deposition and devices of graphene. Nanocrystalline diamond thin films (grain size ~ 200 nm) are coated with a thin Ni layer (nominal thickness ~ 20 nm) and heated to 900°C in a forming gas atmosphere (H2/Ar) to initiate a thermally driven catalytic transformation of the diamond surface into graphene by a reaction of Ni with carbon.

Abstract: In the present study we analyzed an influence of adding of Cu2-xSe nanocrystals (NCs) to PbS quantum dots (QDs) prepared in colloidal solution, in organic matrices and on glass substrates. We found that photoluminescence (PL) signal from QDs is considerably affected by Cu2-xSe NCs, which results in slowdown of PL decay and change of PL intensity. [..] Read more

Abstract: Properties of the resulting polymer nanofibers are often tailored by sonication technique applied prior or past an electrospinning process. The aim of this contribution is to evaluate morphology of nanofibrous mats formed by poly(ethylene oxide) with distributed magnetic nanoparticles (MNP) (about 20 nm in diameter) in dependence on time of sonication of the used polymer solutions.

Abstract: The DC reactive magnetron sputtering of metallic target in oxide atmosphere is a simple method of depositing the undoped (intrinsic (undoped)) nanopolycrystalline layers of metal oxides. We have optimized the deposition of the intrinsic ZnO zinc oxide (ZnO) thin films with submicron thickness 50−500 nm on fused silica glass substrates and investigated the localized defect states below the optical absorption edge down to 0,01 % using photothermal deflection spectroscopy (PDS) in a broad spectral range from UV to IR.

Abstract: The behaviour of added to Al-Mg alloy multi-walled carbon nanotubes (CNT) during fusion arc welding was studied. CNTs were added into gap between two Al-Mg alloy sheets which were welded with tungsten inert gas arc welding process (TIG). [..] Read more

Abstract: The standard methods of transferring graphene onto semiconductor substrates apply acetone to solve the layer of polymethyl methacrylate (PMMA) on the surface of graphene layer at the end of ‘wet transfer process’. During this process, however, impurities on the order of nanometres get entrapped and have a subsequent negative effect on the practical utilization of graphene in the field of optoelectronics.

Abstract: Flexible strain sensors based on MWCNTs/epoxy nanocomposite coated on a polyimide (Kapton HN) substrate are often preferred due to their outstanding properties. Nevertheless, polyimide has a poor adhesion with different classes of materials, such as ceramic, polymers and metals, caused by its hydrophobic nature and low specific surface energy.

Abstract: Wastewater treatment is one of the urgent need because of increasing water pollution. Polymeric nanofibrous composite membranes have been developed for the purpose of wastewater filtration due to small pore size and highly porous structure. [..] Read more

Abstract: Diamond-like carbon (DLC) layers based on amorphous carbon are used for wide range of applications, mostly for mechanical protection of various industrial components. As the properties of DLC layers are closely linked to their structure, we examined them at micro- and nanoscale by two independent microscopic techniques: Scanning Electron Microscopy (SEM) and Atomic Force Microscopy (AFM) with a good agreement.

This work reports a promising avenue whereby mercury (II) ions are removed from aqueous solution using silver nanoparticles immobilized on the surface of modified silica. [..] Read more

Abstract: Ionic interactions between oppositely charged polyelectrolytes and surfactants can - under proper conditions - lead to formation of physical gels. The surfactants form micellar structures enabling to solubilize hydrophobic substances in the otherwise aqueous environment of the gel. [..] Read more
