The ability to mimic the structure of the natural extracellular matrix is a successful key for guided bone regeneration (GBR). For the regeneration of highly organized structures such as heart and bone, aligned fibrous membranes could provide anisotropic mechanical and biological properties which are adequate topographic guidance to cells. Here, novel nanofibrous membranes were developed throug...

Nickel oxide (NiO) nanopowder was obtained during a sonochemical method. Nickel hydroxide precursor, prepared by addition of sodium hydroxide (NaOH) to nickel nitrate Ni(NO3)2 solution and vigorously stirring until the pH becomes 7.2. Ultrasounds waves were applied during precipitation period and after drying in oven nanopowder NiO was achieved. Transient and scanning electron microscopy showed...

We simulated capacitance–voltage (C – V) curves of Si3N4 /GaAs, Si3N4 /Si and also Si3N4 /Semi* ~virtual semiconductor! metal–insulator–semiconductor ~MIS! capacitors and compared them with experimental C – V curves of a Si3N4 /Si/GaAs structure. The experimental C – V curves of the Si3N4 /Si/GaAs MIS capacitors are not in agreement with the simulated C – V curves of the Si3N4 /GaAs and Si3N4 /...

ZrN/Si3N4 multilayer coating that alternates with either nanocrystalline ZrN or amorphous Si3N4 interlayers was fabricated by reactively magnetron sputtering in an Ar-N2 mixture atmosphere. The thicknesses of the nanocrystalline ZrN and the amorphous Si3N4 interlayers are ~12.5 and 2.5 nm, respectively. The ZrN/Si3N4 coating exhibits a promoted hardness of 28.6 ± 1.2 GPa when compared to the bi...

Strontium titanate (SrTiO3) nanopowder has been synthesized through a sol-gelhydrothermal method. The X-ray diffraction studies of SrTiO3 nanopowder have shown that the asprepared powder was single phase, crystalline, and has a cubic perovskite structure (ABO3) with a lattice constant a = 3.903 Å. The particle size calculated from FWHM was ∼22 nm. SrTiO3 nanopowder was examined using thermo gra...

The joining of porous Si3N4 to dense Si3N4 ceramics has been successfully performed using mixed RE2O3 (RE = Y or Yb), Al2O3, SiO2, and α-Si3N4 powders. The results suggested that the α-Si3N4 powders partly transformed into β-SiAlON and partly dissolved into oxide glass to form oxynitride glass. Thus, composites of glass/β-SiAlON-ceramic formed in the seam of joints. Due to the capillary action ...
