Anatase TiO2 nanoparticles with average particle size ranging between 12 and 23 nm were synthesized by metalorganic chemical vapor deposition. The structure determined x-ray diffraction transmission electron microscopy. specific surface areas measured Brunauer-Emmett-Teller ranged from 65 to 125m2∕g. effects on the stability of in air studied for isochronally annealed samples temperature range 700–800 °C. Only anatase rutile phase transformation occurred. With decrease initial onset...
Undoped and Nd3+-doped TiO2 nanoparticles were synthesized by chemical vapor deposition in order to tailor the band gap of TiO2. The doping reduced gap. was measured ultraviolet-visible light absorption experiments near-edge x-ray fine structure. maximum reduction 0.55 eV for 1.5 at. % Nd-doped nanoparticles. Density functional theory calculations using generalized gradient approximation with linearized augmented plane wave method used interpret narrowing. narrowing primarily attributed...
Large band gap semiconductors are typically doped in order to enhance their photocatalytic, photovoltaic, and other chemical optoelectronic properties. The identification of dopant position its local environment essential explore the effect doping. X ray techniques, including extended x absorption fine structure, photoelectron spectroscopy, diffraction, were performed analyze Nd...
Most of the research to date has focused on tailoring interphase adhesion by controlling degree chemical bonding between fiber and resin. The interfacial shear strength (IFSS) been increased as much 40% modified surface [1—3]. However, it is well known that increasing reinforced polymeric composite material often leads a reduction in fracture toughness vice versa [4—12]. In this study, effects mechanical interlocking, addition energy absorption glass fiber/epoxy interphase, were studied...
Advancements in off-world food and fiber production should seek to utilize regolith as a source of nutrients prepare it for use solid plant growth substrate. Towards this goal, aeroponic biowaste streams containing both inorganic root system efflux from plants provide an opportunity accelerated weathering enhancement extraterrestrial soils. To test hypothesis, was built that contained Martian simulant (Mars Mojave Simulant-2; MMS-2), inert sand, no-filter control evaluate the in-line filters...
Phosphorus (P) is vital for plant growth, but its agricultural use limited by soil fixation and environmental loss. This study developed an organic ligand-responsive phosphate release system hybridizing magnesium–iron-layered double hydroxides (Mg–Fe LDH) with pectin from apple citrus (pectin-A/C). Structural properties (PO4) of LDH hybrids different concentrations metal precursors (0.5LDH-A/C, 2.5LDH-A/C) were evaluated. All exhibited higher PO4 sorption than pristine Mg–Fe LDH, 2.5LDH-A...
Abstract Single crystal SmCo 5 nanoparticles with an average size of 3.5 nm are produced by cluster‐beam deposition. When deposited without matrix, the showed a super‐paramagnetic behavior blocking temperature 145 K. Dispersion in carbon matrix results increase both coercivity and temperature. Room coercivities as high 12 kOe obtained for first time mono‐layers dispersed C matrix. δM plots show that interactions samples exchange type, which can decrease overall effective anisotropy according...
The Al-substitution affected not only the basal spacing between adjacent lattice planes but also structural arrangement in goethite which results Al-preferential PO<sub>4</sub> sorption on Al-substituted goethite.
In this work, single crystal L10 FePt nanocubes have been successfully produced by a cluster beam deposition technique without the need of post annealing. Particles deposited dc magnetron sputtering using high Ar pressures on both Si substrates and Au grids for measurement magnetic structural properties, respectively. The uniform size distribution with an average 5 nm. At 1 Torr, particles structure order parameter 0.5 RT coercivity 2 kOe switching fields observed in hysteresis loop. Further...
