Porous periclase-spinel ceramics with 30.5-43.6% apparent porosities were prepared from magnesite and Al(OH)3 via an in-situ decomposition pore-forming technique. The reaction process of the pseudomorphs of magnesite and Al(OH)3 was analyzed through X-ray diffraction (XRD), Scanning Electron Microscopy (SEM) and a mic…
OBJECTIVES: The purpose of the present study was to evaluate the effects of proanthocyanidin (PAC), a crosslinking agent, on the physical properties of a collagen hydrogel and the behavior of human periodontal ligament cells (hPDLCs) cultured in the scaffold. MATERIALS AND METHODS: Viability of hPDLCs treated with PAC…
The synthesized magnetic nanoparticles were stable not only in aqueous media but also in mixtures of water and hydrophilic organic solvents.
Structural anisotropy plays an important role in the thermoelectric properties of the widely used (Bi,Sb)2(Te,Se)3 based materials. In this work, (Bi,Sb)2(Te,Se)3 based alloys have been fabricated by various methods to produce samples with different orientation factors, F. It is demonstrated that the n-type alloys are…
Facile synthesis of phenols using biogenic Cu <sub>2</sub> O NPs without using H <sub>2</sub> O <sub>2</sub> , ligand, base.
Advances in understanding the state and transformation of impurity-related defects in natural diamond have been achieved by means of high-pressure and high-temperature annealing experiments. However, the existing literature featuring complex behaviors of aggregated nitrogen and hydrogen-related defect (3107 cm−1 cente…
Bamboo charcoal was produced by pyrolysis or carbonization process with extraordinary properties such as high conductivity, large surface area and adsorption property. These properties can be improved by activation process that can be done thermally or chemically. In this paper, carbonization and activation process of…
Tc loaded via chelation. The formed nanoplatform displays good stability, cytocompatibility and hemocompatibility in a given concentration range, and can be used for targeted dual-mode single-photon emission computed tomography/magnetic resonance imaging of tumors.
source in basic solution. The obtained catalyst showed superior activity and stability in one-pot deacetalization-Knoevenagel condensation reaction.
A review of the current knowledge on aquatic biofilms with an emphasis on the characteristics and ecology of biofilms in natural ecosystems and a focus on biofilm applications linked to water pollution problems.
Graphene dispersion (GR) was prepared by liquid-phase sonication of graphite and evaluated by XRD, DLS and UV-Vis analysis. It was used to prepare PP@mgGR–TiO <sub>2</sub> , showing positive effects on ARS photodegradation under visible light irradiation.
), the developed PPI-MAL DS-DOTA(Gd) nanocomplexes can be used as an efficient contrast agent for MR imaging of cancer cells in vitro, and animal aorta, renal artery, kidney, and bladder in vivo. Furthermore, tissue distribution studies show that the glycodendrimer/Gd complexes are metabolized and cleared out of the b…
In this report, the piezoelectric, dielectric and ferroelectric characteristics of 0.76Bi <sub>0.5</sub> Na <sub>0.5</sub> TiO <sub>3</sub> (BNT)–0.24SrTiO <sub>3</sub> (ST) with niobium (Nb) (Nb-added BNT–24ST) ceramics synthesized by using a solid-state reaction are described.
A large-size crystal ( <bold>1</bold> ) exhibits a relatively more rapid electrical response compared with common phase transition materials (response time/temperature <italic>t</italic> ≫ 0 s).
Two kinds of water-soluble fluorescent hyperbranched poly(amino esters) were first synthesized by a convenient one-pot approach <italic>via</italic> the A <sub>2</sub> + B <sub>3</sub> Michael addition reaction of trimethylolpropane triacrylate and aliphatic diamines.
We report for the first time the efficiency of heteronuclear Zn/Ln coordination clusters (CCs) as catalysts for the multicomponent Mannich-type condensation that involves amines, aldehydes and boronic acids, known as the Petasis borono-Mannich (RBR) reaction.
In the present work, dynamic electrochemical impedance spectroscopy (DEIS) was used to investigate the corrosion behavior of polypyrrole (PPy)-coated titanium (Ti) in simulated body fluid (SBF) solution.
The morphology and through-film optical properties of nematic liquid crystals (LCs) confined between two surfaces may be engineered to create switches that respond to external electric fields, thereby enabling applications in optoelectronics that require fast responses and low power. Interfacial properties between the…
Albumin stabilization of gold nanostars, which demonstrate high stability, biocompatibility, superior CT contrast, SERS and photothermal cytotoxicity towards cancer cells.
Novel azobenzene-derived β-diketonates (4,4,5,5,6,6,6-heptafluoro-1-azobenzene-1,3-hexanedione (LA), 4,4,5,5,6,6,6-heptafluoro-1-(4-dimethylamino)azobenzene-1,3-hexanedione (LB)) were designed and their complexes with lanthanide cations (La(3+), Eu(3+), Gd(3+), Yb(3+)) were prepared and characterized by (1)H NMR, FT-I…
