Structural and electrical properties of (1-x)Na0.5Bi0.5TiO3-xCoFe2O4 (x = 0.1, 0.2) multiferroic composite ceramic

Publication date: Available online 15 February 2020Source: Materials Today: ProceedingsAuthor(s): Shilpa Thakur, Kusum parmar, Sarita Sharma, N.S. NegiAbstractNa0.5Bi0.5TiO3 (NBT) and CoFe2O4 (CFO) ceramics were synthesized by sol–gel and metallo – organic chemical solution methods respectively. Structural, electrical, dielectric and magnetic properties of (1-x) NBT-(x) CFO (x = 0.1, 0.2) multiferroic particulate composite prepared by mixing NBT and CFO powders in required stoichiometric concentration were studied. The presence of ferroelectric (NBT) and ferrite (CFO) phases had been confirmed by X-ray diffraction analysis (XRD). Room temperature dielectric behavior was studied with varying frequencies. Ferromagnetic behavior was also confirmed by M−H hysteresis loops. The current–voltage (I–V) characteristics were studied by using Keithley 2611 Source Meter.

CONCLUSION: Extensive research have been carried out on various process for preparing Bortezomib and composition thereof. This type of dynamic research will clear the path for many generic players in the United States which lead in reduction of price of the composition and thereby enhancing global health care at cheaper prices.

FDA has granted Emergency Use Authorization (EUA) to Battelle's CCDS Critical Care Decontamination System for processing up to 80,000 respirator masks per system each day. CCDS employs concentrated, vapor-phase hydrogen peroxide (VPHP) for decontamination. The system has been validated to decontaminate masks of SARS-CoV-2, the company reported. The masks are placed on shelves inside a container, and a portable, external VPHP system is hooked up to the outside of container. The system was first envisioned by Battelle as part of a study commissioned by FDA in 2015. That study involved determining the feasibility of N95 respi...
