Abstract
Herein, the performance of asymmetric supercapacitors (ASC) fabricated using ZnCo2O4 (ZCO) nano-hexagons and orange peel-derived activated carbon (OPAC) as electrodes was studied. ZCO was prepared by a double hydroxide method and OPAC was prepared from orange peel followed by KOH activation. For ZCO, the calcination temperature was determined using TGA analysis. The XRD showed the presence of a cubic spinel structure. The chemical structure was analyzed using XPS, FTIR, and Raman spectroscopy respectively. For OPAC, the presence of an amorphous nature was inferred; FTIR and Raman studies indicate the presence of functional groups and defect structure in the material. The presence of ZCO nano-hexagons was observed from SEM and TEM respectively. For OPAC, an interconnected pore structure was observed from the SEM image. The specific capacitance for ZCO and OPAC was found to be 194 F.g-1 and 159 F.g-1 at a current density of 0.25 A.g-1. Further, an ASC was fabricated using ZCO as a positive and OPAC as a negative electrode in 2M KOH-soaked separator. A cell voltage of 1.2 V was achieved and the specific capacitance was calculated to be 64 F.g-1 at 0.25 A.g-1. Further, the cyclic stability and the changes at the electrode/electrolyte interface were studied.

Abstract
Citrus sinensis (L.) Osbeck (Rutaceae), commonly known as the sweet orange, is a popular and widely consumed fruit with several medicinal properties. The present study aimed to perform the in silico screening of 18 flavonoids and eight volatile components from the peel of C. sinensis against apoptotic and inflammatory proteins, metalloprotease, and tumor suppressor markers. Flavonoids obtained higher probabilities than volatile components against selected anti-cancer drug targets. Hence, the data from the binding energies against the essential apoptotic and cell proliferation proteins substantiate that they may be promising compounds in developing effective candidates to block cell growth, proliferation, and induced cell death by activating the apoptotic pathway. Further, the binding stability of the selected targets and the corresponding molecules were analyzed by 100 ns molecular dynamics (MD) simulations. Chlorogenic acid has the most binding affinity against the important anti-cancer targets iNOS, MMP-9, and p53. The congruent binding mode to different drug targets focused on cancer shown by chlorogenic acid suggests that it may be a compound with significant therapeutic potential. Moreover, the binding energy predictions indicated that the compound had stable electrostatic and van der Waal energies. Thus, our data reinforce the medicinal importance of flavonoids from C. sinensis and expand the need for more studies, seeking to optimize results and amplify the impacts of further in vitro and in vivo studies.

Abstract
In this work, we report the performance of the LaCoO3 perovskite oxide as a cathode catalyst for an Al-air battery. LaCoO3 was prepared using the sol-gel method and its suitability as a catalyst has been studied. XRD studies of the perovskite revealed a monoclinic symmetry with no secondary phase being observed. An aggregated morphology with a porous structure was observed from SEM analysis. TEM studies showed that the aggregated LaCoO3 particles exhibited an average diameter of 49.94 nm. The surface area obtained using the BET method is found to be 9.088 m2 g-1. The electrochemical activity of LaCoO3 towards the oxygen reduction reaction (ORR) was higher than that of the bare glassy carbon electrode (GCE). From the kinetic studies, the number of electrons transferred was found to be 4.08, indicating that the reaction occurs through a 4e- pathway. The mass activity and specific activity were found to be 3.05 mA mg-1 and 0.33 mA cm-2 at 1.2 V (vs. the reversible hydrogen electrode (RHE)), respectively. The stability of LaCoO3 was studied using chronoamperometry and impedance analyses, which revealed less charge transfer resistance before and after the stability test. Subsequently, an Al-air battery was fabricated using LaCoO3 as the cathode and Al as the anode. Polyvinyl alcohol (PVA) based KOH gel was used as an electrolyte. The cell exhibited an open circuit voltage (OCV) of 1.35 V with a discharging capacity of 1770 mA h g-1. In addition, the power density was calculated to be 10.04 mW cm-2 at 0.6 V vs. RHE. Our studies suggest that LaCoO3 can be a promising candidate as a cathode for high-performance Al-air batteries.

Abstract
BACKGROUND Neurodegenerative diseases (NDs) have become a common and growing cause of mortality and morbidity worldwide, especially in older adults. The natural flavonoids found in fruits and vegetables have been shown to have therapeutic effects against many diseases, including NDs; however, in general, flavonoids have limited bioavailability to the target cells. One promising strategy to increase bioavailability is to entrap them in nanocarriers. OBJECTIVE This article aims to review the potential role of nanocarriers in enhancing the anti-neuroinflammatory efficacy of flavonoids in experimentally induced ND. METHODS A literature search was conducted in the scientific databases using the keywords "neurodegenerative", "anti-neuroinflammatory", "dietary flavonoids," "nanoparticles", and "therapeutic mechanisms". RESULTS A total of 289 articles were initially identified, of which 45 articles reported on flavonoids. After completion of the selection process, five articles that met the criteria of the review were selected for analysis. Preclinical studies identified in this review showed that nanoencapsulated flavonoids attenuated cognitive impairment and seizure, improved behavioral patterns, and reduced levels of astrocytes. Importantly, they exhibited strong antioxidant properties, increasing the levels of antioxidant enzymes and reducing oxidative stress (OS) biomarkers. Moreover, nanocarrier-complexed flavonoids decreased the levels of the pro-inflammatory cytokines, interleukin 6 (IL-6) and tumor necrosis factor alpha (TNF-α), by inhibiting nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB) and nod-like receptor protein 3 inflammasome activation (NLRP3). They also had remarkable effects on important ND-related neurotransmitters, improved cognitive function via cholinergic neurotransmission, and increased prefrontal cortical and hippocampal norepinephrine (NE) and 5-hydroxytryptamine (5-HT). CONCLUSION Nanoencapsulated flavonoids should, therefore, be considered a novel therapeutic approach for the treatment of NDs.

Abstract
NAD is a cofactor that maintains cellular redox homeostasis and has immense industrial and biological significance. It acts as an enzymatic mediator in several biocatalytic electrochemical reactions and undergoes oxidation/reduction to form NAD+ or NADH, respectively. The NAD redox couple (NAD+ /NADH) mostly exists in enzyme-assisted metabolic reactions as a coenzyme during which electrons and protons are transferred. NADH shuttles these charges between the enzyme and the substrate. In order to understand such complex metabolic reactions, it is vital to study the bio-electrochemistry of NADH. In addition, the regeneration of NADH in industries has attracted significant attention due to its vast usage and high cost. To make biocatalysis economically viable, primary methods of NADH regeneration including enzymatic, chemical, photochemical and electrochemical methods are widely used. This review is mainly focused on the electrochemical reduction of NAD+ to NADH with specific details on the mechanism and kinetics of the reaction. It provides emphasis on the different routes (direct and mediated) to electrochemically regenerate NADH from NAD+ highlighting the NAD dimer formation. Also, it describes the electrocatalysts developed until now and the scope for development in this area of research.

Abstract
Three dimensional flower-like NiO-thermally reduced Graphene Oxide (trGO) nanocomposite was prepared by a simple hydrothermal method. The morphology and structure of the nanocomposite was characterized using Scanning Electron Microscope (SEM), Transmission Electron Microscope (TEM), Energy Dispersive X-ray (EDX), X-ray Diffraction (XRD) and Fourier Transform Infrared (FTIR) spectroscopy. The electrocatalytic oxidation of Dopamine, Ascorbic Acid (AA) and Uric Acid (UA) was investigated using Cyclic Voltammetry (CV). The modified electrode NiO-trGO/GCE showed good electrocatalytic activity compared to bare GCE. The detection of dopamine was carried out using Differential Pulse Voltammetry (DPV) wherefrom the Limit of Detection (LOD) and linear range was estimated to be 50 nM and 10 μM to 500 μM respectively. The selective detection of dopamine in presence of UA and AA was carried out. The NiO-trGO/GCE showed excellent selectivity for the detection of dopamine in presence of UA. However AA was found to interfere in the determination of dopamine. Also, the validity of the present sensor was examined in human biological samples.
