Synthesis and magnetic properties of NiCoOurchin-like nanofibers.

Single-phase NiCoO(NCO) nanoparticles (NPs) with an average particle size of 12 (±3.5) nm were successfully synthesized as aggregates in urchin-like nanofibers via a hydrothermal route. Magnetization data measured as functions of temperature and magnetic field suggest a superparamagnetic-like behavior at room temperature, a ferrimagnetic transition around a Curie temperature∼ 200 K, and a spin blocking transition at a blocking temperature∼ 90 K, as observed at a field of 100 Oe.

Synthesis and evaluation of nanosized aluminum MOF encapsulating Umbelliferon: assessing antioxidant, anti-inflammatory, and wound healing potential in an earthworm model.

Nanoporous aluminum metal-organic framework (Al-MOF) was synthesized via solvothermal methods and employed as a carrier matrix for in vitro drug delivery of Umbelliferon (Um). The encapsulated Um was gradually released over seven days at 37 °C, using simulated body fluid phosphate-buffered saline (PBS) at pH 7.4 as the release medium.

Low-temperature cluster spin glass transition in the single-domain NiCrOnanoparticles.

NiCrOnanoparticles with average particle size ∼15 nm, a single-domain size maintains the bulk canted antiferromagnetic ground state, were synthesized by a microwave combustion method. The magnetic behavior was carefully investigated by static and dynamic magnetic susceptibility measurements. In addition to a spin-glass-like behavior below paramagnetic-ferrimagnetic transition at, the NiCrOnanoparticles demonstrate a low-temperature cluster spin glass transition below the spin canting transition, which manifests itself as a magnetic anomaly peak around ∼12 K (at 100 Oe) in the zero-field cooled magnetization with a relatively stronger field dependence in a 'de Almeida-Thouless' line for spin glasses.

The micro-shear bond strength of resin cements to aged laser bleached enamel after using different desensitizing agents.

Objectives: To evaluate the micro-shear bond strength of two resin cements to aged laser bleached enamel after the application of three different desensitizing agents.

Materials And Methods: Forty extracted human central and lateral incisors were prepared and bleached using laser activation bleaching protocol. The teeth were assigned randomly into four groups for desensitization; G1: No post-bleaching treatment, G2: GC MI Paste Plus, G3: Hydroxyapatite nanoparticles (n-HAP) and G4: Flor-Opal.

Optical parameters and dispersion behavior of potassium magnesium chloride sulfate single crystals doped with Co ions.

Single crystals of potassium magnesium chloride sulfate (KMCS) doped with cobalt ions were grown by slow cooling method. Powder XRD study confirmed the monoclinic structure of the grown crystals. The functional group vibrations were checked through FTIR spectroscopy measurements.
