Contactless Stimulation of Multiple Piezoelectric Devices Using Electric Field
Tanaya Nayak,Biswaranjan Swain,Praveen P. Nayak,Satyanarayan Bhuyan 한국전기전자재료학회 2021 Transactions on Electrical and Electronic Material Vol.22 No.3
The contactless energy transmission scheme using parallel-plate capacitor like structure has been explored which provides a platform for energization of multiple piezoelectric (piezo) components. In the proposed method, ac electric fi eld lines produced by copper electrodes penetrate to the piezo components that are coaxially aligned and positioned in-between at certain distance away from each electrode. Consequently, the components are strongly excited at a point where the functioning electric field source frequency alike with the mechanical resonant frequency of the piezo components. The maximum output power corresponding to optimum load and resonant frequency acquired from the contactless energized multi piezo devices is better than that of power obtained from contactless energized single piezo component by this parallel-plate capacitor electric field generator. The testing results reveal the practicability of non contact stimulation/excitation of multi piezo components simultaneously through electric fi eld.

An efficient load balancing algorithm in the field of cloud computing is absolutely essential in order to have a cloud network with graceful performance satisfying user expectation. Inspite of the existence of handful lightly loaded data centers, numerous heavily overloaded data centers may lead to a performance degradation of overall cloud network. Proper workload distribution may improve the overall performance of the cloud system. Now a day’s eminent cloud division rules are highly demanding algorithm for distributing workloads among various cloud server nodes deployed in cloud-enabled data centers scattered over the geographical regions. For the researcher, cloud division rule and optimal cloud server node searching are the most demanding jobs in load balancing leading towards more efficient cloud network and improve users’ satisfaction. This paper presents an expeditious cloud division rule based on geographical location of the cloud-enabled data centers distributed over earth surface and builds a two-dimensional space partition k-d tree to partition them in order to search intended cloud server node efficiently. Our proposed organization scheme can be utilized for active monitoring load balancing algorithm to improve the resource utilization for high performance in present cloud computing environment.

Highly efficient and stable WO3-embedded hierarchical BiOCl/g-C3N4 (WBG) composites have been synthesizedby a two-step solvothermal route. Phase identification and other structural and microstructuralparameters are evaluated by analyzing the XRD pattern of respective composites employing the Rietveldrefinement technique. HRTEM images reveal that BiOCl and WO3 nanoparticles of size 20–25 and 4–6 nmare embedded uniformly on the surface of g-C3N4 nanosheets respectively. The nanocomposites offeredoutstanding photocatalytic performance by showing degradation of colored dyes, colorless pollutants,tetracycline antibiotics and reduction of Cr (VI). About 95% of RhB dyes within 8 min, 91% phenol within150 min, 85% tetracycline (TC) within a record 20 min have been degraded, and 98% Cr (VI) reducedwithin 10 min from wastewater under sunlight irradiation in the presence of the WBG3 nanocomposite. In addition, the WBG3 nanocomposite shows a significant photocatalytic H2 production rate of 2 mmol. h1 g1. Apart from that, the growth of gram-positive and gram-negative pathogenic bacteria is notablyinhibited by WBG nanocomposite, comparable to the same concentration of the pure drug. This work providesa strong framework to fabricate future-generation photocatalysts for the remediation of organicpollutants and heavy metals and for producing solar light-driven hydrogen evolution.
