Abstract The optical properties of TlInS2xSe2(1‐x)mixed crystals (0.25 ≤ x ≤ 1) have been studied at room temperature through the transmittance and reflectivity measurements in the wavelength range of 400–1100 nm. The spectral dependence of the refractive index for all compositions of studied crystals were obtained. T…
For the heterogeneous oxidative polymerization of thiophene starting homogeneously in organic solvents (e.g., ethanol) using small molecule surfactants such as sodium dodecyl sulfate (SDS) generally fails to form stable dispersed phase because completely dissolved SDS cannot form micelles therein. But, if an appropria…
SUMMARY\nCalotropis procera, a laticiferous arid plant has been identified as a potential petrocrop. It is a potential plant for bioenergy and biofuel production in semi arid regions of the country. Calotropis procera is an erect much branced shrub, 2-3 m high with leaves about 10-13 cm wide by 17-19 cm long. It is a…
Electronic Raman scattering measures a polarization-dependent scattering intensity which can provide information about the location of nodes in the energy gap of an unconventional superconductor as well as its overall symmetry. In this paper, we calculate the Raman intensity in the presence of disorder for several mod…
Abstract The molecular dynamics of new poly (ω‐dodecalactam‐co‐ε‐caprolactam‐co‐propylene oxide) copolymers (DL/CL/PAC) has been investigated by using dynamic mechanical thermal analysis (DMTA) and dielectric relaxation spectroscopy (DRS) measurements. The copolymers were synthesized via anionic polymerization of rele…
Spin precessions in the stripes of $\ensuremath{\alpha}\text{-MnAs}$ films prepared on GaAs(001) are investigated using an all-optical pump-probe method. We find that a large-angle spin precession appears while the stripe width decreases. In addition, the large-angle precession considerably changes the resonance frequ…
Abstract Organic chromophores with charge asymmetry may exhibit significant second‐order nonlinear optical (NLO) properties. Metal complexes have been used as the donor, the acceptor, or as the bridge in some of these chromophores. Metal complexes may also be useful in dipolar chromophore orientation and in the buildi…
This work presents thermochemical data for possible gas phase intermediate species in an industrial rutile chlorinator. An algorithm developed for previous work is employed to ensure that all possible species are considered, reducing the number of important species neglected. Thermochemical data and enthalpies of form…
Active targeting of the liposome is an attractive strategy for drug delivery and in vivo bio-imaging. We previously reported the specific accumulation of Sialyl Lewis X (SLX) liposome to inflamed tissue in arthritic model mice or tumor-bearing mice. SLX-liposome encapsulation with fluorescent substances allows for the…
By applying an exact unitary transformation to a two-band Hamiltonian which also includes the effects due to large pnictogen polarizabilities, we show that an attractive spin-mediated Hubbard term appears in the ${d}_{xz}$, ${d}_{yz}$ nearest-neighbor channel. This pairing mechanism implies a singlet superconducting o…
Electrostrictive polymer composites for energy harvesting have been developed and tested using different types of polymers. A good agreement between the modeled data and actual results was found. Various means of increasing the intrinsic characteristics of the polymers was also studied A comparison between the differe…
Abstract In this paper the role of the preparation route on the sintering temperature, microstructure and transport properties of BaCe0.8Y0.1Zr0.1O3‐δsolid solution has been studied. In particular, the samples were synthesized by means of the solid‐state and molten salt synthesis method. The sample properties were inv…
Bumper bar systems are important automotive structures to help protect passengers during frontal and rear collisions. This paper presents the outcomes of a numerical modelling study of a simple rectangular cross section bumper bar system using the explicit finite element code LS Dyna for a low velocity (16 km/h) centr…
The electronic and transport properties of an edge-modified prototype graphene nanoribbon (GNR) slice are investigated using density functional theory and Green's function theory. Two decorating functional group pairs are considered, such as hydrogen-hydrogen and NH(2)-NO(2) with NO(2) and NH(2) serving as a donor and…
Abstract Classical molecular dynamics simulations have been performed for crystalline germanium with the aim to estimate the thermal effects within the first three coordination shells and their influence on the single-scattering and multiple-scattering contributions to the Ge K-edge extended x-ray absorption fine stru…
The paper presents possibilities and difficulties in nondestructive analysis of small multielement single crystals performed by means of X-ray spectrometry techniques: micro-X-ray fluorescence spectrometry (μ-XRF), energy-dispersive electron probe microanalysis (ED-EPMA), and X-ray photoelectron spectroscopy (XPS). Th…
Recent scanning tunneling microscopy (STM) measurements of the proximity effect in $\text{Au}/{\text{La}}_{2\ensuremath{-}x}{\text{Sr}}_{x}{\text{CuO}}_{4}$ and ${\text{La}}_{1.55}{\text{Sr}}_{0.45}{\text{CuO}}_{4}/{\text{La}}_{2\ensuremath{-}x}{\text{Sr}}_{x}{\text{CuO}}_{4}$ bilayers showed a proximity-induced pseud…
This paper presents the results of a fully coupled nonlinear electromechanical model for corrugated dielectric elastomer sheets currently used in the design of commercially available actuators. We investigate the dependence of the actuation characteristics on the thickness of the sheets and the shape and size of the c…
Abstract Radical dispersion polymerization of glycidyl methacrylate accompanied by CO2 fixation yielded particles of polymers bearing cyclic carbonate and epoxide moieties in the presence of polymeric dispersion stabilizers. Cellulose acetate successfully stabilized the dispersion, whereas poly(N‐vinylpyrrolidone) did…
Ubiquitous physiological monitoring will be a key driving force in the upcoming wireless health revolution. Cardiac and brain signals in the form of ECG and EEG are two critical health indicators that directly benefit from long-term monitoring. Despite advancements in wireless technology and electronics miniaturizatio…
