The influence of oxygen vacancy concentration in nanodispersed non-stoichiometric CeO2-δ oxides on the physico-chemical properties of conducting polyaniline/CeO2 composites
(Electrochimica Acta, 2019)
Cerium oxide (CeO 2-δ ) ultrafine nanoparticles, with the lower (CeO 2-δ -HT) and higher (CeO 2-δ -SS) fraction of oxygen vacancies, were used as anchoring sites for the polymerization of aniline in acidic medium. As a ...
Biliverdin-copper complex at physiological pH
(Dalton Transactions, 2019)
Biliverdin (BV), a product of heme catabolism, is known to interact with transition metals, but the details of such interactions under physiological conditions are scarce. Herein, we examined coordinate/redox interactions ...
Fe3O4 nanoparticles as additives for gamma-ray shielding: Structural and surface characterization
(Scientific Technical Review, 2017)
Monodisperse samples of magnetite nanoparticles in the size range of 5-13nm, were prepared by solvothermal synthesis and coprecipitation method. Obtained nanoparticles were characterized by different measurement techniques: ...
Light controllable TiO2-Ru nanocomposite system encapsulated in phospholipid unilamellar vesicles for anti-cancer photodynamic therapy
(Optical and Quantum Electronics, 2018)
Photodynamic therapy implies a combined use of a photosensitizing medicament and low-intensity light to cause selective damage to the target tissue—tumor. As potential medicament, we use Ru(II)(dcbpy)2Cl2complex, and in ...
Inorganic Nanoparticles In Biology: Drug Carriers And Auxiliary Tools In Bioimaging And Bioanalytics
(Biologica Nyssana, 2018)
Among various nano-scaled materials composed from a spectrum of chemical compounds, inorganic nanoparticles are very attractive due to their physico-chemical properties, as well as their availability, simplicity, possibility ...
Rare-earth (Gd3+,Yb3+/Tm3+, Eu3+) co-doped hydroxyapatite as magnetic, up-conversion and down-conversion materials for multimodal imaging
(Scientific Reports, 2019)
Taking advantage of the flexibility of the apatite structure, nano- and micro-particles of hydroxyapatite (HAp) were doped with different combinations of rare earth ions (RE3+ = Gd, Eu, Yb, Tm) to achieve a synergy among ...
Experimental and statistical survey on local thermal comfort impact on working productivity loss in university classrooms
(Thermal Science, 2018)
The paper presents an experimental analysis of the relationship between local thermal comfort and productivity loss in classrooms. The experimental investigation was performed in a real university classroom during the ...
The Effect of Background Gas on the Excitation Temperature and Electron Number Density of Basalt Plasma Induced by 10.6 Micron Laser Radiation
(Plasma Chemistry and Plasma Processing, 2019)
Time-integrated optical emission spectroscopy was applied for the analysis of emission spectra, and determination of electron densities and excitation temperatures of basalt plasma induced by 10.6 micron laser radiation. ...
Hydrogen Absorption in Pd–Ag Systems: A TPD and Electrical Resistivity Study
(Materials, 2019)
Hydrogen retention in Pd–Ag (silver 21 wt. %) thin foil has been tested by means of temperature-programmed desorption (TPD) in the temperature range 25–200 °C and compared to the resistivity measurements for the purpose ...
Influence of absorbed radiation dose following computed tomography on the antioxidative status in rabbit testicles
(Archives of Biological Sciences, 2018)
In recent years, computed tomography (CT) has become very common in veterinary medicine. It is well known that testicles are organs with high radiosensitivity and their function can be impaired even after exposure to low ...
