An improvement in resistive switching (RS) characteristics of CeO2-based devices has been reported by charge transfer through Al metal as a dopant. Moreover, density functional theory (DFT) calculations have been performed to investigate the role of Al-layer sandwiched between CeO2 layers by the Vienna ab initio simulation package (VASP). Total density of(More)
A new active compensated balanced time constant (BTC) noninverting integrator is proposed. The compensation is achieved by using a voltage follower in the feedback path, and this result in an extremely high Q-factor, namely Q &#8771; |A|<sup>3</sup>. It is also shown, that the use of a voltage follower with the Deboo noninverting integrator will only double(More)
A new and novel UV spectrophotometric method has been developed for the determination Cu(II) in synthetic mixture and water samples. The method is based on complex formation of Cu(II) with cefixime immediately in 1,4-dioxan-distilled water medium at room temperature. The complex showed maximum absorption wavelength at 336 nm. Beer’s law is obeyed in the(More)
