Electrospun mullite fibers from the sol–gel precursor
Mullite fibers with diameters from 400 nm to 10 lm were fabricated from the sol–gel precursors using the electrospinning method. During the precursor synthesis, the hydrolysis was controlled to obtain highly viscous mullite sols. The viscous mullite sols were then diluted and mixed with a small amount of polyethylene oxide. Controlling the precursor rheology and spinning conditions, we obtained...
متن کاملFabrication of Ordered Mullite Nanowhisker Array with Surface Enhanced Raman Scattering Effect
Mullite nanowhiskers are prepared by a facile technique at low temperature using mica and AlF3 as raw material. Mica acts as reactant as well as substrate. By controlling the reaction temperature and holding time, the mullite nanowhisker array with uniform morphology is obtained. The nanowhisker array possesses Al-rich single crystalline with an average of 80 nm in diameter and 20 μm in length....
متن کاملDensification and mechanical properties of mullite–SiC nanocomposites synthesized through sol–gel coated precursors
Mullite–SiC nanocomposites are synthesized by introducing surface modified sol–gel mullite coated SiC particles in the matrix and densification and associated microstructural features of such precursor are reported. Nanosize SiC (average size 180 nm) surface was first provided with a mullite precursor coating which was characterized by the X-ray analysis and TEM. An average coating thickness of...

Background: The commissioning accuracy of Volumetric Modulated Arc Therapy (VMAT) need to be evaluated.Objective: To test and evaluate commissioning accuracy of VMAT based on the TG 119 protocols at local institution. Material and Methods: The phantom, structure sets, VMAT and IMRT beam parameter setup, dose prescriptions and planning objectives were following TG 119 guidelines to c...
متن کاملRadiobiological Model-Based Comparison of Three-Dimensional Conformal and Intensity-Modulated Radiation Therapy Plans for Nasopharyngeal Carcinoma
Introduction: Radiobiological modeling of radiotherapy plans are used for treatment plan comparisons. The current study aimed to compare the three-dimensional conformal radiation therapy (3DCRT) and intensity-modulated radiation therapy (IMRT) plans for nasopharyngeal cancer using radiobiological modeling. Materials and Methods: This study was conducted on 10 patients with nasopharyngeal carci...
