Breakdown characteristics of ferroelectric glass-ceramic capacitors in the PbO-SrO-Na2O-Nb2O5-SiO2 system were studied, including under dc charging and pulse charging. Results revealed that capacitance before and after charging was with no significant alternation. Relationship between dielectric constant and electric field was also explored. Meanwhile, a peculiar phenomenon was found that the breakdown...
Tip-less Electrospinning (TLES) process has been developed to produce polymer nanofibers with high throughput. And the ameliorated collector with parallel top-down configurations of two different materials in conventional electrospinning, such as polyethylene terephthalate (PET)-glass, copper-glass and PET-silicon etc, can achieve patterned nanofibers to expand its future applications. In this paper...
Nanofibers will be of great use in tissue engineering, filtration, protective clothing and micro/nano devices etc. In this paper a facile method is introduced to traditional electrospinning to deposit patterned nanofibers to expand its applications, in which three types of parallel top-bottom configurations of two different materials, that is, plastic (polyethylene terephthalate, PET)-glass, plastic-copper...
