Mechanical characteristics of pure Mg and a Mg/Y2O3 nanocomposite in the 25–250 °C temperature range

Mechanical characteristics of pure Mg and a Mg/Y2O3 nanocomposite in the 25–250 °C temperature range: "

Abstract

In this study, the effect of nano-yttrium oxide particles on the mechanical properties of pure magnesium at elevated temperatures
is investigated. Mg/Y₂O₃ (2 wt%/0.7 vol%) bulk composite was synthesised via a powder metallurgy technique incorporating microwave sintering and hot
extrusion. Tensile properties and Brinell hardness behavior of pure Mg and composite samples in the 25–250 °C temperature
range were investigated. Both tensile and yield strengths of pure Mg and Mg/Y₂O₃ composite samples decreased with an increase in testing temperature. The elongation to failure, however, increased up to
200 °C. At all temperatures, the overall mechanical response of the composite samples was found to be superior compared to
pure magnesium and this is primarily attributed to the presence of Y₂O₃ particles in the magnesium matrix.

Annealing temperature dependence of effective piezoelectric coefficients for Bi3.15Eu0.85Ti3O12 thin films: "

Abstract

The effects of annealing temperatures 600, 650, 700, and 750 °C on microstructure, chemical composition, leakage current,
ferroelectric, dielectric, and piezoelectric properties of Bi_3.15Eu_0.85Ti₃O₁₂ (BET) thin films prepared by metal–organic decomposition were studied in detail. The largest spontaneous polarization 2P
_s (98.7 μC/cm² under 300 kV/cm), remnant polarization 2P
_r (81.7 μC/cm² under 300 kV/cm), dielectric constant ε_r (889.4 at 100 kHz), effective piezoelectric coefficient d
₃₃ (46.7 pm/V under 260 kV/cm), and lowest leakage current (1.3 × 10⁻⁶ A/cm² under 125 kV/cm) of BET thin film were obtained with annealing at 700 °C. The mechanisms concerning the dependence of the
enhancement d
₃₃ are discussed according to the phenomenological equation, and the improved piezoelectric performance could make BET thin
film a promising candidate for piezoelectric thin film devices.

Synthesis of TiO2 nanorods by oriented attachment using EDTA modifier: a novel approach towards 1D nanostructure development

Synthesis of TiO2 nanorods by oriented attachment using EDTA modifier: a novel approach towards 1D nanostructure development: "

Abstract

The synthesis of TiO₂ nanorods with anatase structure has been achieved from the necking of truncated nanoparticles by oriented attachment using
titanium ethylenediaminetetraacetic acid (EDTA) chelated complex as a molecular precursor. The preparation was carried out
under mild conditions using a simple solvothermal process. The influence of EDTA over the growth of nanocrystallites and the
various other factors which contribute to the development of 1D TiO₂ nanostructure are investigated. At a relatively lower temperature, titania nanopowders are obtained, and the anatase phase
crystallization is verified by wide angle X-ray diffraction. The evolution of rod-shaped TiO₂ with tapered edges has been confirmed by transmission electron micrographs. The well aligned lattice fringes of TiO₂ nanorod towards [001] direction is investigated by HRTEM. The SEM images show the surface configuration of overall aggregates
of titania crystallites consisted of primary particles which are densely packed in an orderly texture. The moderate shift
in the absorption band towards higher energy region of the absorption spectrum confirms the weak carrier confinement effect
in the sample.

Optical properties of aluminophosphate glasses containing silver, tin, and dysprosium

Optical properties of aluminophosphate glasses containing silver, tin, and dysprosium: "

Abstract

The spectroscopic properties of a Dy³⁺-doped aluminophosphate glass containing silver and tin were reported. Different oxidation and aggregation states of silver
were obtained by varying silver concentration and glass thermal history. The addition of silver and tin at the lowest concentration
studied results in Dy³⁺ ions emission under nonresonant UV excitation in connection with the appearance of an excitation band around 270 nm, which
is associated to isolated Ag⁺ ions and twofold-coordinated Sn centers. The increase in silver and tin concentration leads to a broadening of aforementioned
band and to the presence of charged silver dimers as evidenced by the appearance of an excitation band around 330 nm. The
data indicated that light absorption might take place at ionic silver species and twofold-coordinated Sn centers, followed
by energy transfer to Dy³⁺ ions. After heat treatment, ionic silver species were reduced to atomic Ag by tin with the subsequent formation of Ag nanoparticles
(NPs) inside the dielectric host. A quenching effect in Dy³⁺ ions luminescence was shown with the presence of the Ag NPs, most notably for excitation of ⁶H_15/2 → ⁴F_9/2, ⁴I_15/2, ⁴G_11/2 transitions, which were in resonance with the dipole absorption mode of the particles. The silver NPs were believed to provide
radiationless pathways for excitation energy loss in Dy³⁺ ions.

Fabrication and growth mechanism of hexagonal zinc oxide nanorods via solution process

Fabrication and growth mechanism of hexagonal zinc oxide nanorods via solution process: "

Abstract

This article presents, the fabrication of perfectly hexagonal zinc oxide nanorods performed via solution process using zinc
nitrate hexahydrate (Zn(NO₃)₂·6H₂O) and hexamethylenetetramine (HMT) at various concentrations of i.e. 1 × 10⁻³ to 10 × 10⁻² M in 50 mL distilled water and refluxed at 100 °C for 1 h. We used HMT because it acts as a template for the nucleation and
growth of zinc oxide nanorods, and it also works as a surfactant for the zinc oxide structures. The X-ray diffraction patterns
clearly reveal that the grown product is pure zinc oxide. The diameters and lengths of the synthesized nanorods lie in the
range of 200–800 nm and 2–4 μm, respectively as observed from the field emission scanning electron microscopy (FESEM). The
morphological observation was also confirmed by the transmission electron microscopy (TEM) and clearly consistent with the
FESEM observations. The chemical composition was analyzed by the FTIR spectroscopy, and it shows the ZnO band at 405 cm⁻¹. On the basis of these observations, the growth mechanism of ZnO nanostructures was also proposed.

Study of tryptophan assisted synthesis of gold nanoparticles by combining UV–Vis, fluorescence, and SERS spectroscopy

Study of tryptophan assisted synthesis of gold nanoparticles by combining UV–Vis, fluorescence, and SERS spectroscopy: "

Abstract We developed a rapid and non-toxic method for the preparation of colloidal gold nanoparticles (GNPs) by using tryptophan (Trp)
as reducing/stabilizing agent. We show that the temperature has a major influence on the kinetics of gold ion reduction and
the crystal growth, higher temperatures favoring the synthesis of anisotropic nanoparticles (triangles and hexagons). The
as-synthesized nanostructures were characterized by UV–Vis absorption spectroscopy, transmission electron microscopy (TEM),
X-ray diffraction (XRD), fluorescence, and surface-enhanced Raman scattering (SERS) spectroscopy. The UV–Vis measurements
confirmed that temperature is a critical factor in the synthesis process, having a major effect on the shape of the synthesized
GNPs. Moreover, fluorescence spectroscopy was able to monitor the quenching of the Trp fluorescence during the in situ synthesis
of GNPs. Using Trp as molecular analyte to evaluate the SERS efficiency of as-prepared GNPs at different temperatures, we
demonstrated that the Raman enhancement of the synthesized gold nanoplates is higher than that of the gold spherical nanoparticles.

Luminescence in rare earth-doped transparent glass ceramics containing GdF3 nanocrystals for lighting applications

Luminescence in rare earth-doped transparent glass ceramics containing GdF3 nanocrystals for lighting applications: "

Abstract Rare earth ions-doped transparent glass ceramics containing hexagonal GdF₃ nanocrystals with a mean size of 16 nm were prepared. Energy dispersive x-ray spectroscopy and luminescence spectrum investigation
evidenced the incorporation of rare earth ions into GdF₃ nanocrystals. The efficient energy transfer from Gd³⁺ to Tb³⁺ was demonstrated in the Tb³⁺-doped glass ceramics, which resulted in an intense green light emission originated from Tb³⁺: ⁵D₄ → ⁷F₆ transition via the sensitization of Gd³⁺. Compared with the precursor glass, the Dy³⁺-doped glass ceramic exhibited longer lifetime and lower yellow-to-blue emission intensity ratio owing to the allocation of
Dy³⁺ ions in the low-phonon-energy GdF₃ environment. Under ultraviolet excitation, the Dy³⁺-doped samples emitted bright white light, indicating their potential application in white light emitting diodes.
