Three types of oxidants, ferric benzenesulfonate (Fe(Bzs)3), ferric paramethylbenzenesulfonate (Fe(p-MeBzs)3), and ferric para-ethylbenzenesulfonate (Fe(p-EtBzs)3) were synthesized. Thermoelectric composites were prepared from these synthesized oxidants doped into a PEDOT matrix, which contained conductive graphene fi…
Oxidative bromination of methane (OBM) has been proposed for methane activation. In this work, methane was brominated by HB1VH2O solution with oxygen as an oxidizing agent to produce methyl bromide. Barium oxide or tungsten oxide on silica were chosen as the catalysts to improve the activity and selectivity of the rea…
The work presented here set out to determine the mechanism in which Notch signaling regulates both MPC differentiation and chondrocyte maturation. We took a candidate gene approach to over express and knockout Notch target genes in vivo and in vitro. To achieve this, we relied on mouse genetics using the Prx1Cre syste…
A full-wave modeling and simulation analysis method is presented for performing sensitivity analysis of artificial uniaxial and biaxial crystals previously reported for study with waveguide measurement systems. Small occlusions were machined into bulk dielectric material to impose effectively biaxial material properti…
Background: Guided bone regeneration (GBR) is used to correct bone defects and build harmonious soft tissue architecture during early implant placement in aesthetic area. Palatal connective tissue graft (CTG) may be used for additional soft tissue thicken- ing. However, additional morbidity caused by the harvesting pr…
This thesis concerns some aspects that have influence on the strength of adhesive layers. The strength is determined by the stress deformation-relation of the layer. This relation is also referred to as cohesive law. The aspects having influence on the cohesive laws that are studied in this work are temperature, fatig…
Cyanobacteria and their stromatolites act as interesting foci, providing an effective lens through which to visualise land surface and spatial, temporal and sacred depth in landscape. Stromatolites date back some 3.5 billion years and form a thread through history, from deep time to the present. Believed to be the pro…
Solid adsorption process is now considered as a potential technique to adsorb CO2 from the flue gas emitted via large industrial plants. Activated carbon was commonly studied as an adsorbent for CO2 capture since it provides potential properties such as high surface area, large pore volume, and low cost. The ability t…
Magnetic stirrer was used to prepare saturated solution. All crystals were grown by slow evaporation process. The FTIR spectra of all grown crystals have been recorded in the range of 400 - 4000 cm–1 using Bruker FT-IR 8400 spectrophotometer by KBr pellet technique. To determine the lattice parameters, powder X-ray di…
The current trends of development of microelectronics require reduction of the sizes of chips and density increasing. In turn, it requires high-quality approaches to production of electronic devices. One of reasons of destruction of tracks of printed circuit boards of chips is formation of pores, their growth and tran…

The Early-Stages of CaSO4 Precipitation from Solution The combination of small– and wide–angle X–ray scattering results in a powerful alliance for studying in situ and real–time the early–stages of precipitation from solution. In this study, these scattering techniques in conjunction with off–line experiments provided…
A series of γ-Al₂O₃ supported Pt–FeOₓ catalysts (Pt–FeOₓ/Al₂O₃) with different Fe/Pt atom ratios were prepared, and their catalytic properties were investigated in the oxidation of formaldehyde. It was found that the catalytic activities of Pt–FeOₓ/Al₂O₃ catalysts are varied with the change of Fe/Pt ratios. Among them…
Biochar and wood ash are widely studied materials for amending and remediating metal contaminated soils, but often used in isolation. In this study, a pot experiment was set up to compare their relative effectiveness at restoring soil health. A multi-element contaminated soil from a former metal mining site was treate…
This study aimed to model numerically the thermal cycling resulting from the steel ASTM A743-CA6NM remelting process. The problem was solved with the support of the commercial software ANSYS / FLUENT ® 14.5 for the three-dimensional case using the finite volume method. The following simplifying assumptions were adopte…
Large-area monolayer graphene can be synthesized by chemical vapor deposition (CVD) on catalytic copper metal surface. However, the graphene from CVD method usually shows inferior properties as compared to theoretical value of perfect graphene without any structural defects including point defects and grain boundaries…
Stability of polycrystalline binary and multicomponent metallic systems at low homologous temperatures depends on the mobility of the interphase boundaries and segregation kinetics of components at these boundaries. If the interphase boundaries move with sufficiently high velocity, the segregation process starts to de…
p-Xylene is valuable raw material for the chemical and petrochemical industries, e.g., for producing polyesters and plasticizers. Currently, p-xylene is produced by methylation of toluene and toluene disproportionation. The shape-selective alkylation of toluene with methanol is also a promising way of producing p-xyle…
The frequent fog and haze make the main pollutant PM2.5 into public view. In this paper,VOCs as one of the important precursors of PM2.5 was introduced. Furthermore, focusing on the VOCs from petroleum and petrochemical refining companies in our country, sources of the VOCs in petrochemical enterprises were introduced…
Nos ultimos anos, as celulas estaminais mesenquimais (MSCs) surgiram como fortes candidatos terapeuticos para a medicina regenerativa do sistema nervoso central (SNC). Durante a ultima decada, as moleculas com caracter neuroregulador secretadas pelas MSCs isoladas de diferentes tecidos tem demonstrado um imenso potenc…
