This study developed a facile, one-pot chemical reduction method for fabricating nickel oxide (NiO) and reduced graphene oxide (rGO) composite materials. Electrochemical measurements illustrate that the NiO/rGO composite electrode with a weight ratio of 6 : 4 yields a maximum specific capacitance of 461 F g −1 and a h…
Heteropolyanions, [GaNb18O54](15-) and [AlNb18O54](15-), have been synthesized and characterized. These represent the first examples of introducing group III elements into the heteropolyniobate family; achieved via compatible alkaline aqueous chemistry of group IIIA monomers and Nb-polyoxoanions. The open structure of…
Ionic transport in nanocrystalline solid oxides is of considerable current interest. Several studies have reported room-temperature proton conductivity in nanoscaled 8 mol% Y2O3-doped zirconia (YSZ), although the location of the transport species is not clear. In this study, nanocrystalline YSZ with a grain size of ∼5…
We present a methodology based on the tandem neutron scattering/fully atomistic molecular dynamics simulations that allows structural and dynamical features of polymer melts at different length scales to be unraveled, mainly in the intermolecular and monomeric range. Its particular success rests on that (i) both techn…
Relatively long-range mass flow at the surface level of amorphous films of azobenzene-based photochromic molecular materials was observed upon angled irradiation using a p-polarized laser beam. According to the same principle, the movement of the fragments of these molecular glasses could be induced by angled irradiat…
Novel spinel hollow nanofibers were synthesized by a convenient single-nozzle electrospinning technique. Based on the composition and morphology results by X-ray diffraction (XRD), scanning electron microscopy (SEM) and transmission electron microscopy (TEM), a ‘gas-push’ model was proposed to elucidate the formation…
Zinc-substituted cobalt ferrites, Co1-xZnxFe2O4 (x = 0.0 – 0.5), were prepared by ceramic processing. The crystal structural, morphological and magnetic properties of the products were determined by X-ray diffractometry (XRD), scanning electron microscopy (SEM), and vibrating sample magnetometer (VSM) respectively. Th…
A successful modification of titanium dioxide (TiO2) nanoparticles surfaces by a grafting-to polymer technique combining catalytic chain transfer and thiol–ene click chemistry is reported. Vinylic end functional polymers were first prepared by catalytic chain transfer polymerization (CCTP) using oligo(ethylene glycol)…
Functional group free graphene materials with high electronic conductivities were prepared via solvothermal reaction of solid sulphur (S) and graphene oxide (GO) in a H2O–NMP or H2O–DMF (1 : 1 in volume ratio) solvent at 110 °C for 10 h. Ultraviolet-visible (UV/Vis) analysis revealed that S exhibited strong reductive…
Use of engineered metal oxide nanoparticles in a plethora of biological applications and custom products has warned about some possible dose-dependent cytotoxic effects. Macrophages are key components of the innate immune system used to study possible toxic effects and internalization of different nanoparticulate mate…
Gas permeability and morphological properties of nanocomposites prepared by the mixing of poly(lactic acid) (PLA), poly(butylene succinate) (PBS), and clay was investigated. While the composition of PLA and PBS polymers was fixed as 80% and 20% by weight, respectively, for all the nanocomposites, clay contents varied…
Blends of poly(lactic acid) (PLA)/thermoplastic starch (TPS) were prepared by extrusion and thermopressing, with proportions of 0.1, 0.2 and 0.3 g of PLA per g TPS. Thermoplastic starch was obtained from the extrusion of 0.30 g or 0.25 g of glycerol per g of starch. The mechanical properties and water vapor permeabili…
Mesoporous Co3O4 with hexagonally ordered cylindrical channels has been synthesized by a single-step method using Pluronic soft micellar templates. The resulting material has been directly compared to isomorphous Co3O4 that was obtained via an established but laborious five-step nanocasting method. The soft template r…
A new non-centrosymmetric rare-earth borate K6Li3Sc2B15O30 has been synthesized by solid-state reaction technique, and a transparent crystal with dimensions of 28 × 28 × 8 mm3 was successfully obtained with a K2O–Li2O–B2O3–LiF flux by the top-seeded solution growth method. Single crystal X-ray diffraction results show…
We report the results of a synchrotron-based high-resolution XPS study of the interaction of L-cysteine (Cys) with well-characterized colloidal gold nanoparticles (NPs, typical size 3-4 nm), which were pre-deposited on highly oriented pyrolytic graphite and then brought into contact with the aqueous solution of Cys by…
IN PREPARATION OF THIS CHAPTER, THE CONTENTS of the fourteenth edition of this manual were drawn upon. The author acknowledges the author of the chapter in the fourteenth edition, Martin B. Price. The current edition will review and update the topics as addressed by the previous author, introduce new technology, and i…
A systematic study of the microstructural response of conventionally cast IN 738 and single crystal CMSX 486 superalloys during linear friction welding was performed. The results revealed that, aside from a significant liquation of various phases that occurred during joining, continuous oxide films formed on the weld…
In this study, we prepare UV-curable polyacrylate–gold nanocomposites (PGNs) for the first time and analyze their thermal properties. The microemulsion architectures of these PGNs contain gold nanoparticles (GNPs) whose surface is modified with carboxyl groups; furthermore, 2-hydroxyethyl methacrylate (HEMA) and methy…
The electronic structures and the bond characters of bulk -Fe with Ti, C, N additions are studied using the first-principls pseudopotential plane-wave method. The total energy and the cohesive energy are calculated, and the Mulliken population, the overlap population, the density of states and the charge density are a…
A coarse grain approach was selected to simulate nanocomposites made of single-walled carbon nanotubes (SWNTs) and poly(methyl methacrylate) (PMMA). Unlike common coarse grain simulations, which employ Lennard-Jones models as the force field between the beads, the current approach used experiment-based data, and hence…
