The multi-input converters play a significant role in developing grid-independent hybrid electric vehicles (GIHEVs). This article describes the design and analysis of a single-ended primary-inductor ...converter (SEPIC)-based novel multi-input DC-DC converter (MIC) for grid-independent hybrid electric vehicles (GIHEVs) that is powered by a solar photovoltaic (PV) panel and a fuel cell. The average large-signal, small-signal, and steady-state modelings are demonstrated to achieve high-quality design and analysis. The proposed converter promises wide output voltage and power flow management at lower duty cycle values. The sources can transfer energy to the load either jointly or individually in this converter with the appropriate operation of the power switches. A hardware prototype is also developed and tested efficiently to uphold the mathematical modeling, design, and operation. With fewer switches, lower voltage stress, and fewer circuit components, the suggested converter claims better gain and higher (96%) efficiency.
The scarce availability of non-renewable sources and the staggering amount of pollution have inevitably provoked many countries to opt for renewable sources. Thence, invariably, more renewable ...energy-based applications are hoarded by market stakeholders. Compared to all spheres of renewable energy applications, a considerable part of the energy is pulled into transportation. Wireless power transfer techniques play a significant role in charging infrastructure, considering the current development and advancement in the automotive industry. It will promise to overcome the widely known drawbacks of wired charging in electric vehicles. The effectiveness of wireless charging depends on coil design, compensation techniques, and the airgap between the coils. However, coil misalignment, improper compensation topologies, and magnetic materials reduce the efficacy. We can improve efficacy by overcoming the problems mentioned above and optimizing charging distance, time, and battery size. This paper comprehensively discussed the various electric vehicle charging technologies in conjunction with common charging standards, a list of factors affecting the charging environment, and the significance of misalignment problems. Furthermore, this review paper has explored the suitable coil design structure and different compensation techniques for an efficient wireless charging network.
Sodium chloride is an essential ingredient in meat products, where it is not only used as a flavoring agent but also to achieve desired textural properties and as an antimicrobial to improve its ...safety and extend shelf-life. Although NaCl plays this multi-functional role in meat products, excessive sodium intake is linked to various negative health consequences such as cardiovascular disease and obesity. Sodium chloride added to ready-to-eat meat products is the largest contributor of sodium. Thus, there is an increased interest in the development of meat products with reduced sodium levels. Strategies to reduce sodium include identification of alternatives to sodium, considering safety and functionality, and including technological innovations and alternative food processing strategies. Several studies have shown that high pressure processing (HPP) can partially compensate for the loss in functional and sensory properties of meat products as a result of NaCl reduction. This review summarizes these studies to date and will highlight the ability of HPP to enhance the safety, shelf-life and quality of sodium-reduced meat products.
Hydrogen peroxide (H2O2) is an eminent biomarker in pathogenesis; a selective, highly sensitive real-time detection of H2O2 released from live cells has drawn a significant research interest in ...bioanalytical chemistry. Binary transition-metal oxides (BTMOs) displayed a recognizable benefit in enhancing the sensitivity of H2O2 detection; although the reported BTMO-based H2O2 sensor’s detection limit is still insufficient, it is not appropriate for in situ profiling of trace amounts of cellular H2O2. In this paper, we describe an efficient, reliable electrochemical biosensor based on Mn2CuO4 (MCO) microspheres to assay cellular H2O2. The Mn2CuO4 microspheres were prepared through a superficial solvothermal method. It is obvious from impedance studies, introduction of manganese into copper oxide lattice significantly improved the ionic conductivity, which is beneficial for the electrochemical sensing process. Thanks to the distinct microsphere structure and excellent synergy, MCO-modified electrode exhibited excellent nonenzymatic electrochemical behavior toward H2O2 sensing. The MCO-modified electrode delivered a broad working range (36 nM to 9.3 mM) and an appreciable detection limit (13 nM), with high selectivity toward H2O2. To prove its practicality, the developed sensor was applied in the detection of cellular H2O2 released by RAW 264.7 cells in presence of CHAPS. These results label the possible appliance of the sensor in clinical analysis and pathophysiology. Thus, BTMOs are evolving as a promising candidate in designing catalytic matrices for biosensor applications.
The thermally induced hydration transition of surface-grafted poly(N-isopropyl acrylamide) (PNIPAAm) brushes was probed by surface plasmon resonance spectroscopy (SPR) and contact angle measurements. ...Data are presented for a PNIPAAm brush film with a dry thickness of ∼50 nm that was synthesized by atom radical transfer polymerization on the surface of a self-assembled monolayer on gold. SPR measurements were taken as a function of temperature in two modes: the quasi-static mode, in which the sample was equilibrated at each temperature for ∼15 min prior to measurement, and the real-time mode, in which SPR reflectivity data were collected as the sample was heated and cooled at ∼4.5 °C/min. Both types of measurement indicate that the hydration transition for the PNIPAAm brush occurs over a broad range of temperatures (∼10−40 °C). This result is in accordance with theoretical predictions that have suggested that polymer brush structures on planar surfaces do not exhibit true critical solubility transitions. Contact angle measurements revealed a discontinuity in the surface wettability at a temperature (∼32 °C) that corresponds to the dilute aqueous critical solution temperature. Taken together, these results suggest that the polymer segments in the outermost region of the brush remain highly solvated until the dilute solution lower critical solution temperature (∼32°), while densely packed, less solvated segments within the brush layer undergo dehydration and collapse over a broad range of temperatures.
A first-of-a-kind latent electrochemical redox probe, ferrocene carbamate phenyl acrylate (FCPA), was developed for the selective detection of cysteine (Cys) and aminoacylase (ACY-1). The ...electrochemical signal generated by this probe was shown to be highly specific to Cys and insensitive to other amino acids and biological redox reactants. The FCPA-incorporated electrochemical sensor exhibited a broad dynamic range of 0.25–100 μM toward Cys. This probe also proficiently monitored the ACY-1-catalyzed biochemical transformation of N-acetylcysteine (NAC) into Cys, and this proficiency was used to develop an electrochemical assay for quantifying active ACY-1, which it did so in a dynamic range of 10–200 pM (0.1–2 mU/cm3) with a detection limit of 1 pM (0.01 mU/cm3). Furthermore, the probe was utilized in real-time tracking and quantification of cellular Cys production, specifically in Escherichia coli W3110, along with a whole blood assay to determine levels of Cys and spiked ACY-1 in blood with a reliable analytical performance.
Ceria nanoparticle is a well-known fuel borne additive for reducing the particulate emissions from diesel engines. Main challenges in the use of ceria nanoparticles are the lack of long-term ...dispersion stability in diesel and their effect on lubricity of diesel. The present work mainly focuses on synthesis of stable ceria nanoparticle diesel suspension and study on their lubricity. Ceria nanoparticles were synthesized by co-precipitation method and nano fluids were prepared by two-step method. The optimum concentration of oleic acid (surfactant) was determined based on critical micelle concentration studies and concentration of ceria nanoparticle in diesel was varied from 5 to 25 ppm. Long term dispersion stability studies using Dynamic light scattering system and Turbidity meter shows 10 ppm as an optimum concentration of ceria nanoparticle in diesel for maximum stability. Tribological properties of modified diesel were studied by a standard pin on disk apparatus. The wear rate was found to be reduced for all the nano additive concentrations in diesel and was least for 15 ppm. Based on studies conducted, 10 ppm is reported as an optimum concentration of nanoparticle in diesel having both enhanced stability and lubricity as compared to other concentrations of ceria nanoparticles in diesel.
