Abstract La 4‐4x Eu 4x Ti 3 O 12 ( x = 0.01‐0.15) nanoparticles were synthesized via the polymerizable complex method. The X‐ray powder diffraction ( XRD ) measurements and Rietveld refinements verified that all the samples crystallized in a pure trigonal perovskite structure. La 4 Ti 3 O 12 has band energy of 3.88 eV…
The effect of different atomic substitutions at Mn sites on the magnetic and magnetocaloric properties in Ni50Mn35Co2Sn13 alloy has been studied in detail. The substitution of Ni or Co for Mn atoms might lower the Mn content at Sn sites, which would reduce the d-d hybridization between Ni 3d eg states and the 3d state…
The effects of the extrusion process and CaO addition amount on microstructure, mechanical, and corrosion properties of AZ31 alloys were investigated by means of optical microscopy (OM), scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS), standard tensile testing, and so on. The grain size of AZ3…
This study was performed to prepare 5-fluorouracil (5FU) containing targeted liposomes for the safety and efficacy enhancement. Liposomes were prepared using thin layer method and transferrin (Tf) was employed as the targeting ligand. Morphology of 5FU-loaded liposomes was assessed by transmission electron microscopy…
Seeking environmentally friendly gas-insulated medium has become a research hotspot in recent years. At present, C3F7CN (Heptafluoro-iso-butyronitrile) is considered to be a potential SF6 environment-friendly alternative gas and some achievements have been made in the study of its insulation and decomposition characte…
Oxides are considered as one of the most promising materials for thermoelectric applications because of their environmental-friendly nature, lower processing cost and better stability at high temperature compared to other intermetallic compounds and alloys. Recently SrTiO3 based perovskites and double perovskites have…
Microwave dielectric spectra of the relaxor ferroelectric PbMg1/3Nb2/3O3 single crystals, (Nb + In) co-doped rutile ceramics, inhomogeneous conducting polyaniline pellets, composites of poly(ethylene terephthalate) and multi-walled carbon nanotubes were used for calculation of transmission and reflection spectra of th…
We investigated polarized infrared and Raman spectra of the multiferroic hexaferrites BaSrCoZnFe11AlO22 (Y-type) and (Ba0.5Sr0.5)3Co2Fe24O41 (Z-type) on cooling from room temperature down to 4 K, and we compared the observed numbers of phonons with factor-group analyses of their lattice vibrations. All phonons can be…
Abstract To assess the effects of grain size and briquetting on glass‐batch melting, we measured the viscosity ( η b ) of an industrial glass batch during its conversion to molten simulated architectural glass within the temperature interval of 1050‐1300°C and at a shear rate of 0.02 s −1 . On the basis of the mass fr…
Abstract We propose that a testing procedure we call wet-peel significantly augments conventional wet paper testing when comparing wet-strength resin efficacy or the influence wood pulp fiber surface treatments on wet paper strength. A thin layer of wet-strength resin is sandwiched between a pair of thin, wet regenera…
Silk fibroin (SF) and konjac glucomannan (KGM) are promising materials in the biomedical field due to their low toxicity, biocompatibility, biodegradability and low immune response. Beads of these natural polymers are interesting scaffolds for biomedical applications, but their fabrication is a challenge due to their…
Abstract In this work, the thermal stability, rheological properties and mechanical properties of ethylene-tetrafluoroethylene copolymer (ETFE)/poly(vinylidene fluoride) (PVDF) blends were investigated by thermogravimetric analysis, rheometer and the tensile test. Thermal results indicated that blends had better therm…
New layered perovskite-type oxyfluorides, CsSrNb 2 O 6 F and CsCaNb 2 O 6 F, were prepared via solid state reactions and their crystal/electronic structures were compared to those of a compositional analogue, CsNb 2 O 5 F which has a 3-dimensional pyrochlore-type structure. The CsSrNb 2 O 6 F and CsCaNb 2 O 6 F phases…
Nanocomposite cotton fabrics with in situ-generated silver nanoparticles (AgNPs) were prepared by using Pterocarpus santalinus (Red sanders) extract in water as a reducing agent. The formation of AgNPs was analyzed by scanning electron microscopy (SEM) coupled with energy dispersive X-ray spectroscopy. The SEM analysi…
Iron (Fe)- and manganese (Mn)-oxidizing bacteria are often cited individually and collectively as putative microorganisms for microbiologically influenced corrosion (MIC). The two groups of microorganisms have in common the ability to attach to surfaces and produce macroscopic accumulations (deposits) of metal oxides/…
The rising demand to reduce sugar in foods has resulted in the need to better understand its structuring properties and contribution to the overall microstructure of products. The effect of sugars on the microstructure of agar fluid gels and their novel foams, including stability, has therefore been studied. Gelation…
Kefiran, an exopolysaccharide produced by lactic acid bacteria, has received a great interest due to a variety of health claims. In this study, we aim to investigate the physicochemical and biological properties of Kefiran polysaccharide extracted from Portuguese kefir grains. The kefir growth rate was about 56% (w/w)…
Multiplex imaging in the red and near-infrared (NIR) should be an enabling tool for the real-time investigation of biological systems. Currently available emitters have short luminescent lifetimes, broad absorption and emission bands, and small Stokes shifts, which limits multiplexing in this region to two colors. NIR…
Co@NiSe2 electrode materials were synthesized via a simple hydrothermal method by using nickel foam in situ as the backbone and subsequently characterized by scanning electron microscopy, transmission electron microscopy, energy-dispersive X-ray spectroscopy, and a specific surface area analyzer. Results show that the…
The aim of this work is to evaluate the effect of chitosan content (1, 3 and 5 wt %) dispersed in polylactic acid (PLA) on the structure and properties of composites. Also, the hydrolytic degradation, and the cell viability and adhesion of human MG-63 osteoblasts are analyzed to determine the composites' suitability f…
