Novel eutectic-directed self-templating strategy is proposed to ‘cast’ PdPtNi nanoporous nanowires with superior bifunctional catalytic activity to both EGOR and GOR.
Two-dimensional transition metal carbides (MXenes) exhibit excellent thermodynamic stability, mechanical strength and flexibility, which make them promising candidates in flexible devices and reinforcements in nanocomposites. However, the dynamic stability may intrinsically determine the preferred adsorption sites of…
Ba2+ doped Bismuth ferrite nanoparticles having general formula Bi1-xBaxFeO3 (where, x = 0.00 and 0.20) were successfully synthesized by sol gel method, using nitrates as a starting material. Ethylene glycol was used as a solvent. The synthesized powder was sintered at 650°C for 4 hours to obtain pure phase BFO. Leach…
to expand their mesopores and simultaneously remove the template. The original mesopores with a pore dimension of 2.41 nm partially collapsed and combined into ultra-large mesopores with an average pore diameter of 13.89 nm without perturbing the original cubic symmetry of the remaining mesopores. The maximum pore dim…
Thermo-sensitive block copolymer decorated GO@ZnS NPs nanocomposite was constructed <italic>via</italic> π–π stacking interaction as a robust fluorescent sensing platform for the selective detection of TNT.
The electronic structures of tetragonal structure of PbTiO3 are analyzed by density functional theory using the PBE exchange–correlation functional and the local density approximation (LDA) in Quantum Espresso simulation package. The calculated relaxed lattice parameters are a = 3.79 Å and c = 3.85 Å, yielding a c/a r…
Synthesis of bismuth complexes of etioporphyrin II, protoporphyrin IX dimethyl ester and three tetraphenylporphyrin derivatives in which iodine atom is an extraligand, was carried out. Obtained compounds were characterized by mass spectrometry, UV-vis, 1 H NMR spectroscopy, and HPLC. The study of X-ray spectra showed…
In this paper, the method of lines is extended to analyze 2-D graphene-based multilayered structures. The graphene plates with tensor conductivity may cover partially or totally the interfaces between two consecutive layers. In this paper, the impedance and admittance transformations through the graphene-contained int…
Tellurium (Te) thin films of various thicknesses (200nm, 275nm, 350nm & 500nm) were prepared on Silicon (Si) using thermal evaporation at vacuum of 10−5 torr. It is observed that the resistivity decreases exponentially with the Increases Temperature. A direct band gap between 0.368 eV to 0.395 eV is obtained at differ…
Poly (vinylideneflouride) (PVDF) thin films were annealed at various annealing temperatures ranging from 70°C to 170°C. This study demonstrates that PVDF thin films annealed at temperature of 70°C (AN70) showed significant enhancement in their dielectric constant (14) at frequency of 1 kHz in comparison to un-annealed…
We introduce a general technique for the design of metasurfaces composed of a large number of meta-atoms that enables efficient multifunctional metasurfaces. As a proof-of-concept, we demonstrate a metalens with 0.78NA and 74% focusing efficiency.
The role of different tailor-made additives and conformers of resorcinol have been investigated to elucidate the mechanism of unidirectional vapour growth of α-resorcinol crystal. Our results show the growth anisotropy is linked with the surface stabilization of the slow growing face.
Biomaterials are often engineered with nanostructured surfaces to control interactions with proteins and thus regulate their biofunctions. However, the mechanism of how nanostructured surfaces resist or attract proteins together with the underlying design rules remains poorly understood at a molecular level, greatly l…
Pure and Rhodamine B doped Poly (vinyl alcohol)/Chitosan composite films are prepared using solution casting method. Fourier transforms infrared spectra (FTIR), Ultraviolet-Visible (UV-Vis), fluorescence studies were used to characterize the prepared polymer films. The FT-IR results show that the appearance of new pea…
We have studied the mechanical properties of a two-dimensional (2D) boron nanoribbon network (BNRN) subjected to a uniaxial or a biaxial tensile strain using first principles calculations. The results show that the 2D BNRN is super-stretchable. The critical tensile strains of the BNRN in the χ-h1 phase along the a- an…
Magnetic resonance imaging (MRI) is one of the most important medical imaging techniques for clinical diagnosis. Contrast agents (CAs) are commonly necessarily used to enhance the imaging quality of MRI and differentiate diseased tissues from normal ones. Herein, we introduced a macromolecular carrier, spherical polye…
Lyotropic liquid crystals, in which nanotubes coated with polyethylene glycol were aligned side-by-side in aqueous dispersions, acted as templates for the construction of surfactant-free gold nanorods with controllable diameters, functionalizable surfaces, and tunable optical properties.
As a result of the increasing environmental awareness, the concern for environmental sustainability and the growing global waste problem, the interest of bio-composites materials is growing rapidly in the last years in order to use them in various engineering fields. Tremendous advantages and opportunities are associa…
Butane-tetra-carboxylic acid (BTCA) and sodium hypophosphite (SHP) were added into cellulose spinning solution. The cross-linked regenerated cellulose fibers were prepared by spinning the solution into a coagulation bath of distilled water and then cured at high temperature. The optimum conditions were obtained accord…
