In this paper, we report on the shape-controlled synthesis of porous FeVO4 nanorods and nanoparticles through a facile route, including hydrothermal synthesis of FeVO4·1.1H2O precursors and sequential post-calcination at 550 °C for 24 h. The porous FeVO4 nanorods and nanoparticles were obtained with reactant concentra…
Magnetic properties of trivalent rare-earth ion substituted nanocrystalline BiFeO3 have been studied for the compositions Bi0.875R0.125FeO3 (R=La, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, and Yb). All compositions show ferromagnetic characteristics at room temperature, with enhanced magnetization after substitution. Ve…
Linear dendritic hybrid materials enable a range of architectural variations which offers novel possibilities in the tailoring of polymeric materials. In this study dendrons based on the 2,2-bis(methylol)propionic acid (bis-MPA) building block, bearing click chemistry moieties in the core and peripheral hydroxyl funct…
Abstract This indium‐doped zinc oxide field effect transistor (IZO‐FET) with a large ultraviolet (UV) detection sensitivity has been fabricated by inkjet printing technique. In darkness, the IZO‐FETs exhibit a saturation current level of about 10 µA, an incremental mobility as high as 8 cm2 V−1 s−1, and a current on/o…
The Incredible Bulk: We investigate and quantify the different contributions in both amorphous and crystalline electrode materials. The results provide a scientific basis for future NiO electrode design. The conclusions and the characterization techniques can also be helpful in understanding other candidate materials…
The MRL/MpJ mouse displays an accelerated ability to heal ear punch wounds without scar formation (whereas wounds on the dorsal surface of the trunk heal with scar formation), offering a rare opportunity for studying tissue regeneration in adult mammals. A blastema-like structure develops and subsequently the structur…
Orb-weaving spider silk fibers are assembled from very large, highly repetitive proteins. The repeated segments contain, in turn, short, simple, and repetitive amino acid motifs that account for the physical and mechanical properties of the assembled fiber. Of the six orb-weaver silk fibroins, the piriform silk that m…
Three novel N-substituted acrylamide monomers containing different carbohydrate residues, 2'-acrylamidoethyl-α-d-mannopyranoside, 2'-acrylamidoethyl-β-d-glucopyranoside, and 2'-acrylamidoethyl-β-d-galactopyranoside, in the pyranose form were synthesized. The corresponding glycopolymer brushes were prepared on silicon…
In this manuscript, we demonstrate metamaterials based on two-dimensional high density arrays of metallic multiwalled carbon nanotubes. They demonstrate a cutoff response toward electromagnetic waves and can be utilized for filtering applications. The plasma frequency, where the metamaterial displayed a sharp change i…
A detailed understanding of synergetic catalytic effect of graphene−metallic nanoparticles composite is challenging and the heart of the graphene-based catalyst. On the basis of density functional theory, we have theoretically studied the confinement of Pt/graphene composite by using the conversion from the ozone deco…
We have created PMMA-CNT matrices by embedding opened-tip vertically aligned multiwalled carbon nanotubes (VA-MWCNTs) with poly(methyl methacrylate) (PMMA). These PMMA-CNT matrices are excellent electron field emitters with an emission threshold field of 1.675 V/μm, more than 2-fold lower that that of the as-grown sam…
We have investigated the spin/orbital phase diagram in the perovskite orthovanadate $R{\text{VO}}_{3}$ ($R=\text{Eu}$, Y, Dy, and Ho) by measurements of magnetization, dielectric constant, specific heat, Raman scattering spectra, and x-ray diffraction, focusing on the interplay between the $\text{V}\text{ }3d$ spin an…
The synthesis of diverse nitric oxide (NO)-releasing network polyesters is described. The melt phase condensation of polyols with a calculated excess of diacid followed by thermal curing generates cross-linked polyesters containing acid end groups. Varying the composition and curing temperatures of the polyesters resu…
ABSTRACT Acid-soluble collagen (ASC) and pepsin-solubilized collagen (PSC) were isolated from silver carp scales (Hypophthalmichthys molitrix) and some biochemical properties of scale collagens were investigated. The yields of ASC and PSC on the dry basis were 0.86% and 2.32%, respectively. Sodium dodecyl sulfate–poly…
Single wall carbon nanotube (SWNT) networks of different loadings were measured by impedance spectroscopy. The resistances of the junctions and bundles have been separated by modeling ac impedance spectroscopy data to an equivalent circuit of two parallel resistance-capacitance elements in series. The junction resista…
We describe field-induced multiaxis rotations of colloids in a nematic liquid crystal. Anchoring of the nematic director to the colloidal platelet's surface and interplay of dielectric and elastic energies enable robust control over colloid orientation that cannot be achieved in isotropic liquids. Because of the aniso…
Graphene has emerged as a promising nanoelectronic material in electronic devices applications and studying two-dimensional electron gases with relativistic dispersion near Dirac point. Nonetheless, the control of the preparation conditions for homogeneous large-area graphene layers is difficult. Here, we illustrate e…
We report on an atmospheric-pressure dc microplasma that can be used to passivate silicon nanocrystals (SiNCs) in ethanol and that stabilizes their optoelectronic properties. We show that microplasma processing enhances the SiNCs photoluminescence intensity by factor of more than ten times and ∼80 nm redshift of its m…
We derive the radial distribution function and the static structure factor for the particles in model nanoparticle-organic hybrid materials composed of nanoparticles and attached oligomeric chains in the absence of an intervening solvent. The assumption that the oligomers form an incompressible fluid of bead-chains at…
We report the synthesis and characterization of five novel Mo-containing polyoxometalate (POM) bisphosphonate complexes with nuclearities ranging from 4 to 12 and with fully reduced, fully oxidized, or mixed-valent (Mo(V), Mo(VI)) molybdenum, in which the bisphosphonates bind to the POM cluster through their two phosp…
