In vitro cell expansion, differentiation for further cell transplantation and biomaterials-cell fundamental assays are still performed more often on inert 2D surfaces than on 3D culture. 3D systems do not allow an easy cell monitoring and may demand higher cell density, being more costly and time consuming. Inert surf…
Cellulose-based liquid crystalline materials can generate stimuli-responsive fibbers and films [1,2]. Changes in orientational order, which can be affected by variation of temperature and UV irradiation as well as by the presence of solvent vapours, give rise to stresses, which result in strains and modifications in s…
Computer simulation has been widely applied in many research fields owing to its superiority in revealing an insight understanding of the phenomena. In this work, molecular simulation method is adopted to model and investigate the gas solubility in polysiloxane materials, aiming to the polymer scientific field. The si…
Excessive production of superoxide (O2•-) in the central nervous system has been widely implicated in the pathogenesis of angiotensin II (AngII)-dependent neurogenic hypertension (HTN). Our group has tried to overcome the failed therapeutic potential of currently available antioxidants by utilizing nanoformulated copp…
The paper is devoted to the study of the corrosion rate of pipeline steels in CO2-Saturated Water and in Water-Saturated CO2 as a function of pressure, temperature and exposure time. Tests were carried out at temperature ranging from 25 to 60°C and at CO2 and pressure ranging from 20 to 145 bar at different exposure t…
Barium titanate (BT) - potassium niobate (KN) nano-structured ceramics with an artificial morphotropic phase boundary (MPB) structure were prepared by a solvothermal method at temperatures below 230 °C. Various characterizations of the BT-KN nano-structured ceramics revealed that the BT/KN molar ratio was 1, the poros…
The development of strategies based on the use of scaffolds for Tissue Engineering and Regenerative Medicine(TERM) has been hindered by the inability of researchers to present solutions to overcome problems mainly related with the biocompatibility of materials andin vivoperfusion of the 3D structures. It is in this co…
We report the simultaneous growth of hexagonal AlB 2 -phase and tetragonal ThSi 2 -phase nanoislands of erbium silicide on the same silicon substrate. As a new technique, the patterned Si(001) surface with pits in a reverse-pyramid shape and {111} sidewalls is taken as the substrate template. The distribution of nanoi…
Mesoporous silicon and silica-based particles have recently been synthesized and proposed for the controlled delivery of several drugs [1,2]. On the other hand, nature and in particular marine organisms have been the source and inspiration for the development of different biomedical applications, including drug delive…
The electromechanical behaviour of a lead-free ceramic multilayer actuator is described. The actuator is made of a Nd-doped bismuth-alkali-titanate ceramic with inner electrodes of an Ag/Pd-alloy. For electromechanical characterization the actuator is under constant mechanical load and the strain over the applied elec…
NOx emission in coke combustion with and without iron oxides were investigated in a fixed bed quartz reactor. Effects of Fe2O3 and Fe3O4 loading on NOx emission were discussed. NOx emission was also studied by simulating test with recycling flue gas with Fe3O4 modified coke as fuel. The results showed that Fe3O4 was c…
Binary compound Y3Fe29cannot be directly formed by rare earth Y and Fe and the third element M (non-iron transition elements) must be introduced to form ternary compound Y3(Fe,M)29. In this work, six alloys with compositions of the Y3Fe29-xCrx(x=1,2,3,4,5,6) were prepared and investigated by X-ray diffraction (XRD), S…
Exhibited and Published 50 years, the thesis about 49 conditions as a whole accounted for 33.3% of papers included. This place back to 100, the more...

The formation of residual stresses in the vicinity of a single defect of continuity in the process of intense impulse loading surface with considerable distance from the defect is examined. Modeling is carried out within the framework of large elastic-plastic deformation. In the vicinity of the defect there is level o…
Bi0.9Pr0.1Fe1-xTixO3 ceramics were prepared by a rapid liquid sintering method. The structure of samples was confirmed by X-ray diffraction and scanning electron microscopy. Ti substitution leads to some changes in the crystal structure of Bi0.9Pr0.1FeO3, which also significantly affects the dielectric constant and lo…
Sr, Ca and Fe doped cathode materials Ln0.7Sr0.2Ca0.1Co0.7Fe0.3O2.85(LnSCCF, Ln=La, Pr and Nd; abbreviated as L-72173, P-72173 and N-72173) were synthesized by microwave sintering (MWS) techniques. The formation process, phase structure and composition were characterized using TG/DTA, XRD and EDS. The thermal expansio…
We have synthesized the Ti1-xFexO2(x=0.01, 0.02, 0.03 and 0.05) nanoparticles by the sol gel method to enhance the photocatalyic property of TiO2.These samples are characterized using x-ray diffraction (XRD), Raman spectroscopy, Ultraviolet /Visible (UV/V) spectroscopy and fluorescence spectroscopy (PL). The x-ray dif…

A sol-gel method combined with spin-coating process has been developed for deposition of nanostructured thin films of La0.85Sr0.15MnO3(LSM) on La0.6Sr0.4Co0.2Fe0.8O3-δ(LSCF) pellets. The quality of the LSM films depends sensitively on the solution chemistry and other processing parameters. It was found that the optima…
