In this study, epoxy composite specimens reinforced with multi-walled carbon nanotube filler were fabricated using shear mixer and ultra-sonication processor. The mechanical and thermal properties of the fabricated specimens were measured and evaluated. From the electron microscope images and the results from the measurements of tensile strengths, the specimens having 0.6 wt% nanotube content s...

Abstract We successfully refined a cheap commercial boron powder by means of high-energy ultra-sonication and utilized it in synthesis bulk MgB 2 . Rietveld phase analysis X-ray diffraction pattern revealed completely formed with low amount MgO. prepared ultra-sonicated ethanol for 15 min showed self-field J c around 300 kA/cm at 20 K without any compromise T (~39 K). Pinning based on Dew-Hughe...

We demonstrate solution-processed photodetectors composed of heavy-metal-free Si nano/micro particle composite. The colloidal Si particles are synthesized by electrochemical etching of Si wafers, followed by ultra-sonication to pulverize the porous surface. With alkyl ligand surface passivation through hydrosilylation reaction, the particles can form a stable colloidal suspension which exhibits...

We demonstrated the ultrastructure of rat glomerular basement membrane (GBM) by ultra-high resolution scanning electron microscopy. GBM prepared by sonication methods and conductive-staining could be observed without metal coating at magnifications as high as 400,000 times. The GBM showed an irregular meshwork structure composed of various strands and pores. The width of the strands ranged from...
