This work examines the difficulties associated with using optical techniques to measure temperature when the device itself emits a significant level of light over a wide spectrum, making it a challenge to separate the useful measurement signal from the device emission. The specific situation considered here is that of…
Aiming at improving the biocompatibility of biomaterial scaffolds, surface modification presents a way to preserve their mechanical properties and to improve the surface bioactivity. In this work, chondroitin sulfate (CS) was immobilized at the surface of electrospun poly(caprolactone) nanofiber meshes (PCL NFMs). The…
The effect of simplifications in nuclear fuel depletion analysis as well as the effect of cross-section uncertainties were evaluated as to their impact upon material attractiveness for weapons diversion purposes. The effect of simplified depletion models for material attractiveness evaluation was evaluated through a c…
Annealing temperature plays an important role in the formation of an Au-Ga eutectic alloy. The effects of the annealing temperature on gold nanoparticles colloid and substrate surface were studied using AFM, FE-SEM and TEM. At 600oC, the layer of gold colloids particle formed an island in the state of molten eutectic…
Magnesiummanganese (MgMn) based alloys with various chemical composition were processed by indirect extrusion at two dierent speeds. Alloying with Mn and rare earth elements has signicant inuence on the microstructure and on the texture of the alloys under investigation. This paper deals with the acoustic emission ana…
A systematic approach for performing a holistic reactivity insertion analysis in research reactors using the RELAP5/MOD3 code is proposed. The intention is to demonstrate, in an orderly manner, a method for determining the limiting reactivity insertion in a research reactor facility. Indispensable constituents of the…
mediciNe & HealtH/RHode iSlaNd partICleS Can be engIneered to nanometer-size (nm) which are only 1/1,000 the width of a single human hair. Nanoparticles made of gold display strong optical absorption. A special type of gold nanoparticle called hollow gold nanoparticle has a core-shell nanostructure with unique charact…
Long life asphalt pavements are designed to provide strong, durable pavement structures having a structural life exceeding 50 years with only periodic removal and replacement of the asphalt surfacing layer required during this period. This paper presents the authorrs design model for long life, flexible composite and…
(K0.5Na0.5)(Mn0.005Nb0.995)O3 (KNMN) thin films of thickness ranging from 200 to 500 nm were deposited on Pt/TiO x /SiO2/Si substrates using a chemical solution deposition. The films exhibit well-established ferroelectric hysteresis loops with a remanent polarization (P r) of 13–16 µC/cm2. Their coercive voltages exhi…
The corrosion resistance of reinforced Carbon steel in saturated Ca(OH)2 solutions has been investigated. The influence of additions of vanadium and titanium micro-alloying elements on the corrosion resistance of carbon steel has been studied using weight loss, open Circuit potential (OCP), potentiodynamic polarizatio…
A Filipowicz, S WoÅowiecDepartment of Cosmetology, University of Information Technology and Management in Rzeszów, Rzeszów, PolandBackground: Bioconjugates of a polyamidoamine (PAMAM) G3 dendrimer and an aldehyde were synthesized as carriers for vitamins A and B6, and the bioavailability of these vitamins for skin nu…

Here we report the performance of surface functionalized diamond surfaces as biosensing platform for human immunodeficiency virus trans-activator of transcription (HIV-Tat) peptide detection. Comparative investigations were conducted on nanocrystalline diamond (NCD) and polycrystalline diamond (PCD) films. Scanning el…
The results of testing of Pd(II)-Cu(II)/Bent catalyst samples in the reaction of CO oxidation with air oxygen are presented. Bentonites from three Ukrainian deposits: Gorbskoye, Dashukovskoye, and Kirovogradskoye are used as supports. Natural bentonites, their modified forms, and the catalysts have been characterized…
Piezoelectric properties of ferroelectric Bi 4 Ti 3 O 12 (BiT) single crystals have been investigated by a resonance–antiresonance method. Large and high-quality single crystals of BiT were obtained via top-seeded solution growth under a high oxygen pressure of 0.9 MPa. The elastic and piezoelectric constants in the (…
The 24%Fe-36%Ni/Al 2 O 3 catalyst was prepared using sol-gel method. This research investigated many variable factors for conversion synthesis gas to C 2 –C 4 light olefins by using Fisher-Tropsch synthesis. The effects of calcination atmospheres and calcination heating rates and also operation conditions such as the…
To prepare fine and even poly(N-vinyl carbazole) (PVCz)/polystyrene (PS) blend webs, we performed a series of experiments varying processing parameters, including the type of solvent, PVCz/PS blend ratio, applied voltage, and tip to the collector distance (TCD). It was found that the morphology and the average diamete…
Flexible polyurethane nanocomposites (PUNCs) containing recycled polyether polyols received from chemical recycling of original corresponding foams were synthesized by the incorporation of organically functionalized Cloisite 30B montmorillonite (MMT). Different amounts of MMT (1-3%w) were added to the polyol mixture p…
