Microencapsulation of cells is a technique in which cells are enclosed in microscopic spheroids of a desired substance, with applications in many fields, such as biomedical engineering. In this study, a microfluidic approach to encapsulate bacteria (nontoxic to humans) in polyethylene glycol-diacrylate (PEG-DA) sphero…

Design shrinking beyond the resolution limits of 193 nm optical lithography requires the introduction of double patterning technology (DPT) for the semiconductor industry. Two consecutive lithography and etching process (LELE; Litho-Etch-Litho-Etch) and self aligned double patterning (SADP) process are major two optio…
Thanks to averaging processes and Γ-convergence techniques, we are able to link a microscopic description of ferromagnetic materials based on spin lattices and their mesoscopic description in the static framework for the three fundamental contributions: exchange, magnetostatics and external. The results are in accorda…
For each $N\ge C_dt^d$ we prove the existence of a well separated spherical $t$-design in the sphere $S^d$ consisting of $N$ points, where $C_d$ is a constant depending only on $d$.
Graphene, the atomic-thin layer of carbon atoms, was first isolated on an insulating substrate in 2004 by two groups in Manchester University [1, 2] and Columbia [3]. Those milestone experiments established the Dirac nature of the charge carriers in graphene. The same year, C.L. Kane and E.G. Mele predicted that intri…
We review the preparation, phase transfer, surface modification and possible bioapplications of hydrophobic CdSe based quantum dots (QDs). CdSe cores with rod and spherical morphologies were prepared through adjusting preparation conditions. The photoluminescence (PL) of the QDs depended strongly on preparation condit…
In general, steel is protected from corrosive environments by conversion coatings, that is, phosphating, chromating, and so forth, and then followed by different layers of paints. Nowadays, strict pollution laws and regulations are creating significant challenges for coating experts to develop an environmentally frien…
The radioactivity concentrations of nuclides (238)U, (232)Th and (40)K in lake sediments collected from 15 different stations at Altınkaya dam lake and 12 different stations at Derbent dam lake in Turkey were measured using high-resolution gamma-ray spectrometry. The measurement was done using a coaxial HPGe detector…
A method for hyphenating surface enhanced Raman scattering (SERS) and thin-layer chromatography (TLC) is presented that employs silver-polymer nanocomposites as an interface. Through the process of conformal blotting, analytes are transferred from TLC plates to nanocomposite films before being imaged via SERS. A proce…
The K-BKZ constitutive model is now 50 years old. The paper reviews the connections of the model and its variants with continuum mechanics and experiment, presenting an up-to-date recap of research and major findings in the open literature. In the Introduction a historical perspective is given on developments in the l…
High Resolution Image Download MS PowerPoint Slide By employing 31 P multiple-quantum coherence-based solid-state nuclear magnetic resonance spectroscopy, we present the first comprehensive experimental assessment of the nature of the orthophosphate-ion distributions in silicate-based bioactive glasses (BGs). Results…
Two mordanting agents, aluminum potassium sulfate and aluminum acetate, in three concentrations (5%, 10%, and 20% owf) were evaluated for colorfastness to laundering and light of natural dye extracts (madder, weld, and coreopsis) on cotton print cloth. The type of aluminum mordant had a greater influence on colorfastn…
DEER (double electron-electron resonance) is a powerful pulsed ESR (electron spin resonance) technique allowing the determination of distance histograms between pairs of nitroxide spin-labels linked to a protein in a native-like solution environment. However, exploiting the huge amount of information provided by ESR/D…
We report synthesis, characterization, and properties of a multifunctional oxalate framework, {KDy(C 2 O 4 ) 2 (H 2 O) 4 } n ( 1 ) (C 2 O 4 2– = oxalate dianion) composed of two absolutely different metal ions in terms of their size, charge, and electronic configuration. Dehydrated framework ( 1′ ) exhibits permanent…
Nanosized graphene quantum dots were prepared by acid etching of carbon fibers and used as effective substrate supports for platinum nanoparticles which were synthesized by thermolytic reduction of platinum(II) chloride in ethylene glycol. Transmission electron microscopic measurements showed that the resulting nanoco…
Adsorption and release of the biologically active nitric oxide (NO) was evaluated over a series of highly flexible iron(III) dicarboxylate MOFs of the MIL-88 structure type, bearing fumaric or terephthalic spacer functionalized or not by polar groups (NO 2, 2OH). As evidenced by ex situ X-ray powder diffraction and in…
The low temperature transport and magnetic properties were investigated in the misfit-layered Ca 2 Co 2 O 5 compound. The compound exhibits incommensurate spin-density-wave (SDW) state in the dχ -1 /dT curve at 20 K, which is confirmed by the resistivity (ρ) characterization. The resistivity shows an upturn from metal…
This work was focused on the production and characterization of lightweight and water resistance particle boards with various lignocellulosic materials of the annual plants hemp (Cannabis sativa L.), canola (Brassica napus L.) and bagasse (Saccharum officinarum L.) in admixtures with industrial wood. Some chemical pro…
