We report the synthesis of new laterally alkyl substituted high birefringent quaterphenyl and phenylethynyltolane liquid crystals with isothiocyanate terminal group. The thermal and optical properties such as birefringence are measured and discussed based on their molecular structures. The compounds exhibit birefringe…
This study investigated the mechanisms, using microscopy and strength testing approaches, by which the addition of maleic anhydride grafted high-density polyethylene (MAPE) enhances the mechanical properties of basalt fiber-wood-plastic composites (BF-WPCs). The maximum values of the specific tensile and flexural stre…
Semiconducting polymer X-radiation detectors are a completely new family of low-cost radiation detectors with potential application as beam monitors or dosimeters. These detectors are easy to process, mechanically flexible, relatively inexpensive, and able to cover large areas. However, their x-ray photocurrents are t…
The surface primary amines of generation five poly(amido amine) (G5 PAMAM) dendrimer were modified by different amounts of carboxybetaine acrylamide (CBAA). As a result, the fully modified molecules (CBAA-PAMAM-20, obtained from the 20:1 molar ratio of CBAA molecules to amino groups in modification solution) show exce…
We report on structural distortions in extreme-electron density ($\ensuremath{\sim}6\ifmmode\times\else\texttimes\fi{}{10}^{14}\text{ }\text{ }{\mathrm{cm}}^{\ensuremath{-}2}$) confined quantum wells of ${\mathrm{SrTiO}}_{3}$ embedded in ${\mathrm{GdTiO}}_{3}$. Sr-column displacements are measured using high-angle ann…
We report a synthesis method to stabilize TiO 2 rutile nanoparticles (around 10 nm) and keep the particle size when reduced down to TiO 1.84 . TiO 2−δ nanoparticles exhibit room-temperature ferromagnetism that becomes stronger for TiO 1.84 . The reduction mechanism to stabilize Magneli phases excludes a relevant influ…
PURPOSE: Contrast agents for chemical exchange saturation transfer MRI often require an accurate measurement of the chemical exchange rate. Many analysis methods have been reported that measure chemical exchange rates. Additional analysis methods were derived as part of this study. This report investigated the accurac…
Strongly alkaline electrolyzed water (SAEW) was prepared by electrolysis of tap water in a laboratory-made water electrolyzer. The pH of stored SAEW was stable for more than one month. The hardness of the electrolyzed water was 30% lower and the Na(+) concentration was 18% higher than those of the tap water. Silkworm…
Friction behaviour of an ultrananocrystalline diamond film deposited by the microwave plasma-enhanced chemical vapour deposition technique is studied in a controlled humid atmosphere. The value of friction coefficient consistently decreases while increasing the humidity level during the tribology test. This value is 0…
Assessing dose in nanoparticle-cell interactions is inherently difficult due to a complex multiplicity of possible mechanisms and metrics controlling particle uptake. The fundamental unit of nanoparticle dose is the number of particles internalized per cell; we show that this can be obtained for large cell populations…
The reaction of [Co(II)(NO3)2]·6H2O with the nitroxide radical, 4-dimethyl-2,2-di(2-pyridyl) oxazolidine-N-oxide (L(•)), produces the mononuclear transition-metal complex [Co(II)(L(•))2](NO3)2 (1), which has been investigated using temperature-dependent magnetic susceptibility, electron paramagnetic resonance (EPR) sp…
One-dimensional arrays of gold quantum dots (QDs) on insulating boron nitride nanotubes (BNNTs) can form conduction channels of tunneling field-effect transistors. We demonstrate that tunneling currents can be modulated at room temperature by tuning the lengths of QD-BNNTs and the gate potentials. Our discovery will i…
The Tm 3+ /Er 3+ /Yb 3+ co-doped Y 2 O 3 –ZnO nano-composite is synthesized using the solution combustion technique. The structural morphology is monitored using x-ray diffraction, transmission electron microscopy and scanning electron microscopy. The Yb 3+ /Tm 3+ co-doped nano-phosphor emits intense blue as well as w…
The polymeric ouzo effect, a nanoprecipitation process, is used for the preparation of polysaccharide-based nanoparticles. Dextran, pullulan, and starch were esterified with hydrophobic carboxylic acid anhydrides to obtain hydrophobic polysaccharides, which are insoluble in water. The additional introduction of methac…
Acetylene (C 2 H 2 ) and copper foil have been chosen as carbon precursor and catalyst, respectively, for the synthesis of graphene by atmospheric pressure chemical vapor deposition. The effects of hydrogen (H 2 ) concentration on graphene growth have been studied by Raman spectroscopy and transmission electron micros…
ABSTRACT Magnetoelectric polymer nanocomposite is synthesized using conducting polyindole and nano‐sized magnetite (Fe3O4) particles through the in situ polymerization method. The effect of nanoparticles content on the polyindole matrix is studied by Fourier transform infrared (FTIR) and ultraviolet (UV) spectroscopy,…
We study the structural and magnetic orders in electron-doped ${\mathrm{BaFe}}_{2\ensuremath{-}x}{\mathrm{Ni}}_{x}{\mathrm{As}}_{2}$ by high-resolution synchrotron x-ray and neutron scatterings. Upon Ni doping $x$, the nearly simultaneous tetragonal-to-orthorhombic structural (${T}_{s}$) and antiferromagnetic (${T}_{N…
Vanadium dioxide (VO2) is a key material for thermochromic smart windows that can respond to environmental temperature and modulate near-infrared irradiation by changing from a transparent state at low temperature to a more reflective state at high temperature, while maintaining visible transmittance. Here, we demonst…
It generally requires a complex workup procedure for the fabrication of Au@Ag heterogeneous nanostructures with an accurate morphology by the present multistep seed-mediated growth approaches. In this paper, we present a new and straightforward method for the controllable synthesis of uniform Au@Ag heterogeneous nanor…
The present research work deals with the surface modification of natural cellulosic polymers to develop novel materials for different applications. Natural cellulose-graft-poly (methyl acrylate) copolymers were prepared using the free radical induced graft copolymerization technique. Different reaction parameters were…
