We present a first-principles study of the electronic transport properties of micrometer long semiconducting CNTs randomly covered with carbene functional groups. Whereas prior studies suggested that metallic tubes are hardly affected by such addends, we show here that the conductance of semiconducting tubes with stan…
The new EUV Lithography tools for IC High Volume Manufacture at 22nm make use of EUV radiation at λ= 13.5nm. High power Laser (LPP) and Discharge (DPP)EUV light sources are based on Sn plasmas for the optimum conversion of electrical power to in-band radiation. Sn-fueled sources emit debris such as Sn particles in a r…
The main ability of amphiphilic molecules is to alter the energy of interfaces. They aid in the formation of various materials characterized by a high surface to volume ratio. Furthermore, amphiphiles tend to self-organize into structures of higher complexity. In the current study anionic surfactants containing a pure…
Superhydrophobic, highly transparent, and stable organic-inorganic composite nanocoating is successfully prepared by a simple sol-gel dip-coating method. This method involves control of the aggregation of inorganic colloid particles by polymerization and ultrasonic vibration to create the desired micro/nanostructure i…
We have designed and realized a three-dimensional invisibility-cloaking structure operating at optical wavelengths based on transformation optics. Our blueprint uses a woodpile photonic crystal with a tailored polymer filling fraction to hide a bump in a gold reflector. We fabricated structures and controls by direct…
The effect on the physico-chemical properties of introducing the sulfur atom into the molecular structure of liquid crystals is discussed and rationalized in terms of existent theories; a comparison is made with the corresponding hydrocarbon and oxygen derivatives.
Vitrification is currently the most widely used technology for the treatment of high level radioactive wastes (HLW) throughout the world. Most of the nations that have generated HLW are immobilizing in either borosilicate glass or phosphate glass. One of the primary reasons that glass has become the most widely used i…
We present the correlation between film fabrication conditions (crystallization temperatures), microstructure, and dielectric phase shift of Ba1−xSrxTiO3 (BST) thin films synthesized by metal organic solution deposition (MOSD) on sapphire substrates. The structure, microstructure, surface morphology, and composition o…
Vertisols comprise some of the important arable land in northwestern Turkey. Five sites were selected to present vertisols occurring in different parent materials of the study area. These soils occur on flat to gently sloping plains of the region. Clay content is high in the studied sites. The high cation exchange cap…
Silver nanoparticles (Ag-NP) on silica were produced in aqueous solution by deposition of silver on colloidal silica in a small cuvette using radiation from a xenon-mercury lamp. Ag-NP were also synthesized on a much larger scale with low-level, long-term visible light irradiation for several months. In both cases, th…
In this study we tried to find the influence of fiber type, fiber fineness and knit construction on the amount of softener pick up by the fabric. Decision trees are developed to explain the cationic softener pick up depending upon the factors mentioned above. The influence of the type of load (mixed fiber load and ind…
A joint experimental and theoretical investigation of the spin 1/2 system ${\text{Cu}}_{2}{({\text{PO}}_{3})}_{2}{\text{CH}}_{2}$ suggests a description of this compound as coupled alternating antiferromagnetic Heisenberg chains. Magnetic susceptibility, specific heat, nuclear magnetic resonance, nuclear quadrupole re…
In this article, we have demonstrated that many representative problems of optical technologies can be accurately and effectively solved with the commercially available FDTD software, provided that such software offers the flexibility applying partial analytical knowledge to the problems. This is the case with scalar…
Abstract Polymer blending is an effective method for providing desirable polymeric materials with properties useful for the packaging industry. In the study reported, blends of chitosan/poly(ethylene oxide) (PEO) were prepared in various weight ratios with and without glycerol. Line profile analysis of the X‐ray diffr…
We consider a model for the solidification of an ideal ternary alloy in a mushy layer that incorporates the effects of thermal and solutal diffusion, convection and solidification. Our results reveal that although the temperature and solute fields are constrained to the liquidus surface of the phase diagram, the syste…
First-principles calculations for colloidal PbS nanocrystals reveal a sizable dependence of surface energy on the solution environment. In vacuum, the bare (100) surface is more stable than the bare (111) surface. Methylamine adsorption, however, preferentially lowers the energy of the unreconstructed (111), but the l…
Two groups of the laterally methyl-substituted 1:1 associates between 4-(4′-pyridylazo-3-methylphenyl)-4″-substituted benzoates and 4-substituted benzoic acids were prepared to investigate the effect of different substituents, either on the pyridine-based derivatives or on the acid component, on the extent and stabili…
Recent experimental evidence has suggested that bioinspired techniques represent promising avenues toward the production of functional nanomaterials that possess a high degree of activity. These materials are prepared under synthetically simple and efficient conditions, thus making them attractive alternatives to many…
In this paper, the functionalized monomer (TFAASi) behaves as a linkage to be immobilized into inorganic composite host gels through covalent bonds. Subsequently two kinds of Eu-centered chemically bonded hybrid gels (Eu-TFAA-Si-O-Ti, Eu-TFAA-Si-O-B) with composite hosts have been prepared and characterized. The coval…
This approach provides a new technique to synthesize silver nanoparticles (AgNPs) using CO(2)-expanded liquids (CXLs) as the processing medium. A soluble form of silver carboxylate, silver isostearate (AgISt), was synthesized and characterized. The XRD and DSC analyses indicated that the methylated branched alky chain…
