Chemosensor of Gold(I) 4-(3,5-Dimethoxybenzyl)-3,5-dimethyl Pyrazolate Complex for Quantification of Ethanol in Aqueous Solution

We have developed a robust method for the detection of heavy metal ions zinc, cadmium, and mercury in water. In this study we have synthesized a hydrogel based on biopolymer that is raw wool obtained from eszvMarino sheep and used this hydrogel as heavy metal ion sensor in the water. We have incorporated meta-benziporphodimethene ligand in-situ in the hydrogel synthesis, which shows selectively color-changing characteristics when immersed in Zn2+, Cd2+ and Hg2+ metal ions aqueous solution. This hydrogel shows selective response towards Zn2+, Cd2+ and Hg2+ metal ions in a competitive environment. Meta-BPDM was responsible for the selectivity of hydrogel towards Zn2+, Cd2+ and Hg2+ metal ions in water. This selective sensing behavior of raw wool based hydrogel has given a novel existence to our study. The synthesized hydrogel was studied for sensing applications and characterized by using FTIR, TGA, and SEM techniques.

“…This can be explained by the kind of interaction occurring between metal ions and meta-BPDM. [25][26][27][28][29][30][31][32] .…”

“…First it uses single phased clock, and second is reduction in the transistors driven directly by the clock and the third factor is, it uses lesser number of transistor in the circuit. At the same time the major drawback of TCFF is that, the design has a longer setup time despite of the significant enhancement in the power consumption [20][21][22][23][24][25][26][27][28] .…”

The power efficiency and speed are two main concerns in any digital as well as analog circuit design. In this work, we analyze the pulse-triggered flip-flop (PTFF). In PTFF have two main stages, the pulse generator (PG) and the latch circuitry. We have utilized PG that has four transistors which is less than the number of transistors comparison to the previously used PGs. The design has been implemented on Cadence Virtuoso using 22nm CMOS cell library. The various parameters like data-to-output (D-to-Q) delay, leakage power and power-delay product (PDP) are being compared with existing flip-flop circuits like master-slave flip-flop (MSFF), DFF and conventional PTFF. The modified PTFF shows 24.3% improvement in D-to-Q delay and 18.1% improvement in PDP as contrast to the conventional PTFF.

“…In a nine-switch converter [25][26][27] a common dc voltage source is shared between two inverters i.e., Inverter 1 and Inverter 2 for upper and lower load respectively. Generally, the voltage utilization for each inverter is equal.…”

Space Vector Modulation for Nine-Switch Converter Employing Three Phase Loads

Different power utilities require different voltage levels and sources (AC/DC) for its operation. In this process converters are required where lot of power is being wasted in components as switching & conduction losses. One way to reduce losses is to reduce the number of switches in the converter. This paper proposes a nine-switch converter where two loads are controlled using a single inverter having nine-switches resulting in less conduction & switching losses as well as less space and cost. Finally, this work shows the simulation of nine-switch converter operating with space vector modulation and employing two three phase loads.
