Recent advances in energy storage devices have earned recognition for the rapid development of sustainable chemistry in the synthesis of metal oxides using plants and their components as reducing agents. In this study, Mentha piperita leaf extract was used as a reducing agent to synthesize zinc oxide (ZnO) for use in supercapacitors along with starch as stabilizing agent. Three powder samples, ZnO (Zn), ZnO reduced with Mentha piperita leaf extract (ZnM), and ZnO reduced with Mentha piperita leaf extract stabilized with starch (ZnMS) were synthesized and systematically characterized. Among the samples, ZnO reduced with Mentha. piperita leaf extract stabilized with starch (ZnMS) exhibited a larger crystallite size according to XRD analysis, and showed a rod-shaped morphology as observed in SEM and FESEM analyses. The presence of oxygen vacancies were confirmed by EDAX, a higher specific surface area from BET analysis, and a reduced optical band gap of 2.99 eV from optical studies. The electrochemical studies for the as prepared materials were made with three-electrode configuration. The electrode made using the powder sample ZnO reduced with Mentha piperita leaf extract stabilized with starch (ZnMS) coated on a graphite sheet exhibited a specific capacitance of 56 F/g at 1 A/g and retained 99
We investigate the impact of a dark matter density spike surrounding the Milky Way's supermassive black hole (SMBH) on the detectability of Singlino-dominated neutralino dark matter within the Next-to-Minimal Supersymmetric Standard Model (NMSSM). Similar density enhancements, or mini-spikes, around stellar-mass black holes (sBHs), have also been considered. Such a dark matter (DM) candidate typically produces weak indirect detection signals in conventional dark matter halos. Additionally, a Singlino-like lightest supersymmetric particle (LSP) is very difficult to probe at the LHC or through the direct DM search experiments. On top of that, recent observation of the LUX-ZEPLIN 248 keV Nuclear-Recoil Event may hint towards a DM that can be accommodated by a Singlino with mass more than 200 GeV. Keeping these in consideration, we examine the prospects for detecting these sub-TeV dark matter scenarios through gamma-ray observations of the regions surrounding the SMBH Sgr A^∗ and the sBH in the low-mass X-ray binary XTE J1118+480.
A series of undoped and 1-9 mol% Eu3+ doped Ba2La4Zn2O10 phosphor are synthesized via solution combustion route utilizing Gaseteria brachyphylla (G. brachyphylla) gel as fuel. The optimized phosphor is explored for its potential in optical thermometry and latent fingerprints (LFPs) visualization applications. Under 394 nm excitation, Eu3+ doped Ba2La4Zn2O10 phosphors exhibited strong red emission associated with D-5(0)-> F-J transitions. The calculated Commission Internationale de l'& Eacute;clairage (CIE) coordinates (x = 0.6335, y = 0.3656) confirmed that the emitted light lies in the red spectral region, with an exceptional color purity (CP) of similar to 87.05 % with correlated color temperature (CCT) of 1876 K. Judd-Ofelt (J-O) parameters (Omega(2), Omega(4)) and other radiative properties are analyzed through photoluminescence (PL) emission spectra to gain insights into the luminescent behavior of Ba2La4Zn2O10:Eu3+ phosphors. The temperature-dependent emission study demonstrated that the luminescence intensity retained 88.57 % of its initial value at 420 K, with a high activation energy (E-a) of about 0.24 eV, highlighting the material's excellent thermal stability. The maximum relative sensitivity (S-r ) of the Ba2La4Zn2O10:5Eu(3+) phosphor is determined to be 2.46 % K-1 at 300 K. Furthermore, bright, clear red-emitting fingerprint images are developed using the powder-dusting method on multiple surfaces, including magazine paper, painted wood, and glass. These images exhibited excellent clarity, revealing well-defined Level I-III ridge features under 365 nm UV light. These results suggest that Ba2La4Zn2O10:5Eu(3+) phosphors hold strong potential for display technologies and LFPs visualization applications.
In the context of univalent function theory, special functions play an important role and have been studied by a number of researchers earlier. This article presents and examines two subfamilies of bi-univalent functions that are governed by Bernoulli polynomials in the open unit disk. We obtain limits on initial coefficients for functions in the specified subfamilies. The FeketeSzeg & ouml; problem is also addressed for the elements of the subfamilies that have been defined. We also present some new results and discuss pertinent links to earlier findings.
An analysis that contrasts various methods for managing a microgrid's operations in a community context is known as comparison research on control strategies for community microgrids. The study's objectives are to evaluate the benefits and drawbacks of various control schemes and to pinpoint the best approach for enhancing the microgrid's performance. Control methods include islanded mode control, hybrid mode control, grid-connected mode control, and advanced control strategies that combine economic dispatch with optimum power flow are usually compared in the research. A comparison is established. Depending on elements including resilience, cost-effectiveness, efficiency, stability and dependability. The comparative study's findings shed light on the optimal control approach for a particular community microgrid taking into account the resources that are available, the local energy consumption, and other variables. This review also emphasizes the advantages of using advanced control systems, these systems maximize energy management, maintain grid stability, and improve overall system performance by controlling the intricate interactions among distributed energy resources (DERs), such as solar photovoltaics, wind turbines, energy storage, and conventional generators. Energy efficiency will be increase in rural locations with high solar radiation and limited wind power by using advanced methods and grid-connected mode management. Demand response reduces dependency on external grids and associated expenses while improving resilience. Customized control strategies are essential for maximizing community microgrid performance.
