Lignocellulosic agro-based biomass is one of the most plentiful and sustainable resources that can be leveraged as an adsorbent material for wastewater treatment. Designing and running efficient biomass processing facilities requires deep knowledge of the physicochemical, thermal, and morphological properties of lignocellulosic biomass. This study investigates the physicochemical properties of Musa acuminata pseudostem fiber (BP), Moringa oleifera bark (MB), and Hevea brasiliensis sawdust (HBS) to evaluate their potential as raw materials for adsorbent preparation. Comprehensive characterization of these biomasses was conducted using FESEM, EDS, XRD, FTIR, TGA, and BET techniques. BP exhibited the lowest bulk density and the highest porosity, suggesting a looser structure with more void space, which may enhance adsorption capacity. HBS demonstrated the highest true and bulk densities, the lowest porosity, and the lowest ash content (2.56%), alongside the highest carbon (42.56%), hydrogen (7.51%), volatile matter (71.09%), and fixed carbon (17.60%) contents, indicating a dense structure with potential for enhanced adsorption and regeneration ability. MB possesses the highest oxygen content (49.93%), which enhances its potential for adsorbing polar substances. Crystallinity index (CrI) values of 19%, 21.8%, and 26.7% for BP, MB, and HBS, respectively, confirmed their predominantly amorphous nature, which is favorable for adsorption. FTIR analysis confirms the presence of hydroxyl, carboxylic, carbonyl, and amino functional groups in all three materials, signifying their potential for heavy metal adsorption. Furthermore, the abundance of biomass in Tripura, India, makes it a readily available resource, enhancing its applicability and appeal for adsorbent development.
The latest developments in the Internet of Medical Things (IoMT) have transformed healthcare, allowing for the easy transmission of sensitive data across networked medical equipment. However, this interconnection has produced a fertile environment for cybersecurity threats, necessitating the use of sophisticated intrusion detection systems. This work proposes a fresh classification of an attack detection algorithm for IoMT, as well as a method comparison and dataset categorization to improve detection performance. The aim of research is to propose and evaluate an attack detection algorithm for IoMT, focusing on improving detection performance against man-in-the-middle attacks. The study focuses on man-in-the-middle attacks, a common concern for the security of IoMT communication. The suggested intrusion detection technique employs machine learning algorithms, where real-time data from the St. Louis Enhanced Healthcare Monitoring System (WUSTL-EHMS) is used for evaluation, proving the Variational Autoencoders (VAEs) better performance with 91.61
Fast and reliable monitoring of metabolic biomarkers, including glucose and lactate, is critical for chronic diseases, sepsis, and other scenarios involving physiological stress. However, most diagnostic options depend on multiple serial tests, require complicated testing apparatus, and are too expensive to be useful in the point-of-care arena. To address these limitations, we present a portable, low-cost, and 3D-printed (3DP) electrochemiluminescence (ECL) biosensor capable of simultaneously detecting glucose and lactate in a single step. The biosensor incorporates interdigitated electrodes (IDEs) within a bipolar electrode (BPE) electrochemical system to enhance electron transfer and signal amplification. Through careful optimization of voltage, luminol concentration, and pH, strong and reproducible ECL signals were achieved, with detection limits of 0.1 mM for glucose (linear range 0.1 mM to 5.0 mM) and 80 µM for lactate (linear range 0.1 mM to 4.0 mM). Real serum analysis yielded 95-102% recovery rates, validating the device's clinical relevance. Combining an inexpensive smartphone-based readout and fabricated with low-cost carbon and polylactic acid (PLA) filaments, this device offers a scalable and field-deployable approach to real-time, decentralized diagnostics. The proposed prototype fills a critical void between laboratory analysis and standard healthcare needs and promotes accessible and affordable metabolic monitoring for underserved populations.
Among the most pressing global concerns are those related to sustainable energy supply, effective water recycling, and comprehensive water management. Scarcity of clean water is often exacerbated by inadequate saline water management, highlighting the need for innovative solutions. The current study explores an advanced thermal energy storage system based on a parabolic dish solar collector, which is integrated with a desalination unit. This system utilizes pure paraffin wax and various nano-enhanced phase change materials, including mono, binary, and ternary configurations. The setup features two water tanks coupled with the parabolic dish solar collector and phase change material section, where the phase change materials are implemented in different phases: mono (Al2O3, CuO, MWNCNT), binary (Al2O3-CuO, CuO-MWCNT), and ternary (Al2O3-CuO-MWCNT) nanocomposites. Key performance indicators analyzed in this research include temperature behavior, thermal efficiency, water yield, and economic feasibility. The results demonstrate accumulated water yields of 4.82, 6.95, 7.61, 8.36, 8.88, 9.28, and 9.81 L/m2 for each respective phase change materials module. Among the selected PCMs, the ternary Al2O3-CuO-MWCNT nanocomposite possess higher energy efficiency of 82.46 % with the cost per litre of $0.02213. Notably, binary nano-enhanced phase change materials outperforms pure paraffin wax and mono nano-enhanced phase change materials, while ternary nano-enhanced phase change materials exhibits superior performance over binary nano-enhanced phase change materials. This innovative approach offers significant potential for reducing the cost and energy requirements of water purification systems, providing an economically viable alternative for facilities looking to optimize their reverse osmosis purification processes.
