Extrinsic electronic states to tune the luminescence and bonding nature of Cs2NaInCl6 double perovskite
Double perovskites; Electron density analysis; Red phosphors; Transition metals doped phosphors
Halide double perovskites have been extensively investigated in recent years as more stable and environmentally friendly materials with significant optoelectronic properties. Herein, we introduce Mn2+ ions in the Cs2NaInCl6 lattice to impart new electronic pathways to the otherwise weak optically active double perovskite for tuning its luminescent behaviour. X-ray diffraction, Raman, UVvisible, Photoluminescence (PL), and timeresolved PL (TRPL) spectroscopy are used to investigate the effect of Mn 2+ feed ratio on structural, vibrational, and optical properties. The chemical environment and surface morphology of the Mn2+ ions doped Cs2NaInCl6 double perovskite were investigated using X-ray photoelectron (XPS), energy dispersive X-ray (EDS) spectroscopies, and scanning electron microscopy. Results of the Rietveld refinement and Raman spectra divulge a decrease in In-Cl and Na-Cl bond length upon Mn2+ incorporation. The microstructure of the Cs2NaInCl6 double perovskite system was also studied using HRTEM analysis. UVvisible studies demonstrated a tremendous increase in absorption and a slight increase in band gap upon Mn2+ doping. PL and TRPL measurements of Mn2+: Cs2NaInCl6 discloses its red luminescence at 614 nm corresponding to the d-d atomic transition of Mn2+ with a long lifetime of 2.1 ms. Electron density investigations using maximum entropy method (MEM) demonstrate clear evolution of In-Cl and Na-Cl bonds from a highly ionic nature in pure Cs2NaInCl6 to strong covalent nature in Mn2+: Cs2NaInCl6 double perovskites. This affirms the simultaneous replacement of In, Na ions by Mn2+ to maintain charge neutrality in the compound and tune the electronic states of the Cs2NaInCl6 system. 2023 Elsevier B.V.

Extrinsic pseudocapacitance: Tapering the borderline between pseudocapacitive and battery type electrode materials for energy storage applications
Batteries; Energy storage; Extrinsic pseudocapacitance; Hybrid energy storage devices; Pseudocapacitance; Supercapacitor
Extrinsic pseudocapacitance, which can also be referred to as induced pseudocapacitance, is, at present, one of the most widely explored fields in energy storage. Extrinsic pseudocapacitive mechanism can be imparted to an otherwise diffusion-controlled faradaic energy storage material by external methods like size engineering, compositional modification, doping, anion intercalation, and morphological modifications. As a significant mechanism that plays a borderline role between battery-type and pseudocapacitive nature of energy storage, extrinsic pseudocapacitance tends to narrow down the boundary between these conventionally diverse systems, which in turn would contribute a lot to the development of hybrid energy storage technologies. For effective utilization in upcoming energy storage technologies, a critical analysis on the effect of this mechanism on reported devices shall turn into a valid account. This review gives a detailed insight into extrinsic pseudocapacitance, its significance, and recently reported materials, methods, and devices. The future outlook and challenges in transforming extrinsic pseudocapacitive mechanisms into a promising strategy for next-generation energy storage devices are also discussed. 2023 Elsevier Ltd

Eye-Tracking Measures in Aviation: A Selective Literature Review
Objective: The aim of this article is to present a comprehensive review of eye-tracking measures and discuss different application areas of the method of eye tracking in the field of aviation. Background: Psychophysiological measures such as eye tracking in pilots are useful for detecting fatigue or high-workload conditions, for investigating motion sickness and hypoxia, or for assessing display improvements and expertise. Method: We review the uses of eye tracking on pilots and include eye-tracking studies published in aviation journals, with both a historical and contemporary view. We include 79 papers and assign the results to the following three categories: Human performance, aircraft design, health and physiological factors affecting performance. We then summarize the different uses of eye tracking in each category and highlight metrics which turned out to be useful in each area. Our review is complementary to that of Ziv (2016). Results: On the basis of these analyses, we propose useful application areas for the measurement of eye tracking. Eye tracking has the potential to be effective in terms of preventing errors or injuries by detecting, for example, fatigue or performance decrements. Applied in an appropriate manner in simulated or real flight it can help to ensure optimal functioning of manmachine systems. Conclusion: Further aviation psychology and aerospace medicine research will benefit from measurement of eye movements. 2018, 2018 The Author(s).

Eye-Vision Net: Cataract Detection and Classification in Retinal and Slit Lamp Images using Deep Network
Aquila optimization; Be-resnet101; Cataract detection; Crnn; Dense cnn; Grade classification
In the modern world, cataracts are the predominant cause of blindness. Early treatment and detection can reduce the number of cataract patients and prevent surgery. However, cataract grade classification is necessary to control risk and avoid blindness. Previously, various studies focused on developing a system to detect cataract type and grade. However, the existing works on cataract detection does not provide optimal results because of high detection error, lack of learning ability, computational complexity issues, etc. Therefore, the proposed work aims to develop an effective deep learning techniques for detecting and classifying cataracts from the given input samples. Here, the cataract detection and classification are performed using two phases. In order to provide an accurate cataract detection, the proposed study introduced Deep Optimized Convolutional Recurrent Network_Improved Aquila Optimization (Deep OCRN_IAO) model in phase I. Here, both retinal and slit lamp images are utilized for cataract detection. Then, the performance of these two image datasets are analysed, and the best one is chosen for cataract type and grade classification. By analysing the performance, the slit lamp images attain higher results. Therefore, phase II uses slit lamp images and detects the type and grade of cataracts through the proposed Batch Equivalence ResNet-101 (BE_ResNet101) model. The proposed classification model is highly efficient to classify the type and grades of cataracts. The experimental setup is done using MATLAB software, and the datasets used for simulation purposes are DRIMDB (Diabetic Retinopathy Images Database) and real-time slit lamp images. The proposed type and grade detection model has an accuracy of 98.87%, specificity of 99.66%, the sensitivity of 98.28%, Youden index of 95.04%, Kappa of 97.83%, and F1-score is 95.68%. The obtained results and comparative analysis proves that the proposed model is highly suitable for cataract detection and classification. 2022, International Journal of Advanced Computer Science and Applications.

f(Q) gravity as a possible resolution of the H0 and S8 tensions with DESI DR2
CMB; DESI DR2; f(Q) gravity; Gravitational wave data; H0; S8 tension
The symmetric teleparallel framework brings about the possibility of alleviating cosmological tensions. The current burning issue in cosmological studies is the increase in discrepancies in measurements from several surveys. Here, we have focused on and tensions, which are important factors in describing the evolution of the Universe from primordial perturbation to late-time acceleration. Additionally, the consistency of the sound horizon is verified against the Planck results. The gravity model is constrained using recently obtained data. Implementing gravitational wave data to study late-time acceleration is one of the key features of our study. Since standard sirens show promising results, the implementation of gravitational waves to probe dark energy is an interesting study. Through our work, we introduce this possibility by performing statistical MCMC analysis for late-time cosmological evolution. Also, the and tensions are explored utilizing gravitational wave data alongside other prominent datasets, such as the latest DESI BAO, redshift space distortion, cosmic chronometers, Pantheon+SH0ES, and cosmic microwave background data. With the results obtained, we analyzed the profile of cosmological parameters. Finally, the study presents the tension of the model with observations, which is found to have a much lower magnitude compared to the current trend. Thus, the considered f(Q) model alleviates tension, making it the best candidate for further investigation. The Author(s) 2025.

Responsive surfaces; Soft substrates; Surface morphology; Topographical pattern; Wrinkles
Morphology of soft materials, including those of natural systems has great influence in controlling their surface functionalities and responses to external stimuli. Surface morphological features of natural soft systems are produced through controlled cell growth and tissue growth. Artificial systems capable of emulating the morphology-dependent physicochemical responses of natural soft substrates can be prepared through various methods such as surface oxidation, thermal stress, compressive stress, etc. Wrinkling is an important morphological irregularity on soft substrates which can be leveraged in this direction. Wrinkling in artificial soft systems can be achieved through several experimental strategies such as compressive stress, thermal stress, surface oxidation, etc. The tunable, reversible and responsive nature of wrinkled soft substrates make them a potential tool for numerous applications in electronics, optics, adhesives, etc. In this review, have briefly summarized and commented on recent developments in different types of wrinkled soft substrates, their preparation, and emergent applications. 2022 Wiley-VCH GmbH.

Fabrication of biopolymeric sheets using cellulose extracted from water hyacinth and its application studies for reactive red dye removal
Biodegradation; Biopolymer; Cellulose; Dye removal; Reactive red; Water hyacinth
Driven by the imperative need for sustainable and biodegradable materials, this study focuses on two pivotal aspects: cellulose extraction and dye removal. The alarming repercussions of non-biodegradable food packaging materials on health and the environment necessitate the exploration of viable alternatives. Herein, we embark on creating easily degradable biopolymer substitutes, achieved through innovative crafting of a biodegradable cellulose sheet sourced from extracted cellulose. Concurrently, the significant environmental and health hazards posed by textile industry discharge of wastewater laden with persistent dyes demand innovative treatment strategies. This study extensively investigated four distinct methods of cellulose extraction from water hyacinth, a complex aquatic weed. The functional groups, crystallinity index, thermal stability, thermal effects, and morphology of the extracted cellulose were characterized by FTIR, XRD, TGA, DSC, and SEM. This exploration yielded a notable outcome, as the most promising yield (39.4 0.02% w/w) emerged using 2% sodium chlorite and 2% glacial acetic acid as bleaching agents, surpassing other methods. Building on this foundational cellulose extraction process, the extracted fibers were transformed into highly biodegradable cellulose sheets, outlining conventional packaging materials. Moreover, these cellulose sheets exhibit exceptional efficacy in adsorbing reactive red dye, with the adsorption capacity of 71.43 mg/g by following pseudo-second kinetics. This study establishes an economically viable avenue for repurposing challenging aquatic weeds into commercially valuable biopolymers. The potential of these sheets for dye removal, coupled with their innate biodegradability, opens auspicious avenues for broader applications encompassing commercial wastewater treatment procedures. 2023 Elsevier Inc.

After 3000 charging-discharging cycles, the device maintains its cycling stability with 87% capacitance retention. A supercapacitor device is assembled utilizing bismuth ferrite/graphitic carbon nitride/N-doped graphene quantum dots and activated carbon as electrodes. This device shows a significantly improved performance with an energy density of 53.1 Wh kg?1 and a power density of 705.4 W kg?1. As a result, the composite electrode developed in this study is proved to be a potential electrode material for high-performance energy storage devices. 2022

Fabrication of electrochemical sensors for pharmaceuticals and biologically significant molecules
Newer properties of electrochemical sensors for various target molecules are being developed in continuum. Such sensors have attracted a lot of attention due to their simplicity, high sensitivity and trace-level detection of analytes in real samples. Sensor is a system that on stimulation by any form of energy undergoes change in its own state which helps to analyze the stimulant qualitatively and quantitatively. In the thesis studies presented, we have also described the development of electrochemical sensors for the determination of pharmaceuticals and biologically significant molecules. This can be achieved by modifying newlineelectrodes by electrochemical method. Electrode modifiers like metal nanoparticles dispersed on conducting polymers and carbon nanospheres were employed for modification of carbon fiber paper working electrode substrate. These modified electrodes were physicochemically characterized by X-ray diffraction (XRD), Field emission scanning newlineelectron microscopy (FESEM) with energy-dispersive X-ray spectroscopy (EDS), Transmission electron microscopy (TEM), Raman spectroscopy, Fourier transform infrared (FTIR) spectroscopy and X-ray photoelectron newlinespectroscopy (XPS) and electrochemically characterized using Cyclic voltammetry and Electrochemical impedance spectroscopy (EIS). newlineThe modified electrodes have exhibited remarkable electrocatalytic behaviour towards oxidation or reduction of chosen analytes. These modified electrodes were used as electrochemical sensors after optimization of experimental conditions. Under optimal conditions, the sensors have displayed significantly an ultra-low level detection limit with wide linear response and high selectivity towards analyte in the newlinepresence of other interfering substances. newlineThe ultrasensitivity and reliability of the fabricated sensors towards analyte of interest were effectively determined in real samples.

Fabrication of Kaempferol Loaded Zein Nanoparticles: Investigation of in Vitro Cytotoxicity and Apoptosis Induction in Oral Cancer Cells
Apoptosis; Cytotoxicity; Kaempferol; Oral cancer; Zein
Oral cancer remains a significant health challenge, necessitating innovative therapeutic strategies to enhance treatment efficacy and minimize side effects. This study investigates the potential of kaempferol-loaded zein nanoparticles (KZNPs) for this purpose. Kaempferol, a flavonoid with anticancer properties, has poor water solubility, limiting its effectiveness. Zein nanoparticles (ZNPs) offer a promising delivery system for such bioactive compounds. UV-Vis spectroscopy identified Kaempferols absorption peaks at 347 and 253nm, which shifted to 338nm when encapsulated in ZNPs, indicating a change in ??* conjugation. Dynamic light scattering (DLS) and scanning electron microscopy (SEM) confirmed that sodium caseinate (SC) stabilizes ZNPs, resulting in spherical particles with optimal size and stability. Fourier transform infrared (FTIR) spectroscopy suggested enhanced hydrogen bonding between Kaempferol and zein. Differential scanning calorimetry (DSC) revealed the absence of Kaempferols crystalline peaks in KZNPs. The encapsulation efficiency (EE) was 98.39%, and drug release studies showed a controlled release of 79% kaempferol over 8h. In vitro assays demonstrated that KZNPs significantly increased Kaempferols cytotoxicity against PCI-13 oral cancer cells without affecting normal NIH3T3 cancer cells. Overall, these results demonstrate that our KZNPs enhanced biocompatibility and anticancer properties for oral cancer cells.
