Abstract Arterial stenosis is a critical condition with increasing prevalence among pediatric patients and young adults, making its investigation highly significant. Despite extensive studies on blood flow dynamics, limited research addresses the combined effects of nanoparticles and arterial curvature on unsteady pulsatile flow through multiple stenoses. This study aims to analyze the influence of nanoparticles on blood flow characteristics in realistic curved arteries with mild to severe overlapped constrictions. Using curvilinear coordinates, the thermal energy and momentum equations for nanoparticle-laden blood were derived, and numerical results were obtained through an explicit finite difference method.

Abstract Here, we report a comprehensive study on the characterization of cotton biomass residue, its conversion into carbon-based materials via pyrolysis, and its application as an electrochemical sensor for ascorbic acid (AA). The compositions, morphologies, and structures of the resulting materials were investigated using XRD, FTIR, TGA, SEM, and EDS. Pyrolysis was carried out in an air atmosphere at different temperatures (300°C and 400°C) and durations (1, 60, and 240 min), leading to the transformation of lignocellulosic cotton residue into carbon-based materials embedded with inorganic nanoparticles, including carbonates, sulfates, chlorates, and phosphates of potassium, calcium, and… More > Graphic Abstract

Abstract Electrospinning has gained significant importance across various fields, including biomedicine, filtration, and packaging due to the control it provides over the properties of the resulting materials, such as fiber diameter and membrane thickness. Chitosan is a biopolymer that can be utilized with both natural and synthetic copolymers, owing to its therapeutic potential, biocompatibility, and biodegradability. However, producing electrospun chitosan is challenging due to its high solution viscosity, which often results in the formation of beads instead of uniform fibers. To address this issue, the spinnability of chitosan is significantly enhanced, and the production of continuous More >

Abstract Spinal cord injury presents a significant challenge in regenerative medicine due to the complex and delicate nature of neural tissue repair. This study aims to design a conductive hydrogel embedded with magnetic MgFe₂O₄ nanoparticles to establish a bioelectrically active and spatially stable microenvironment that promotes spinal cord regeneration through computational analysis (BIOVIA Materials Studio). Hydrogels, known for their biocompatibility and extracellular matrix-mimicking properties, support essential cellular behaviors such as adhesion, proliferation, and migration. The integration of MgFe₂O₄ nanoparticles imparts both electrical conductivity and magnetic responsiveness, enabling controlled transmission of electrical signals that are crucial for guiding… More >

Abstract The production of crops is badly affected by climate change globally. Mitigation of adverse effects of climate change is in need of time through different management practices such as developing tolerant genetic resources, hormonal applications to boost defense systems, nanoparticles, and balanced fertilization. The nano-hormonal synergy had the potential to mitigate the adverse effects of climate change by modulation of morpho-physiological and biochemical activities. Plant growth, yield, and quality can be enhanced with the supplementation of nano-hormonal interactions. Therefore, the current study explores the synergy between nanoparticles and phytohormonal use. The nanoparticles, even in low… More >

Abstract Phalaenopsis orchids are economically important ornamental crops; however, their commercial micropropagation is often limited by poor rooting efficiency and inconsistent growth. In this study, we investigated the effects of silver nanoparticles (Ag-NPs) on the in vitro regeneration and growth of Phalaenopsis cultivar 611B to determine the optimal concentration of Ag-NPs for improved micropropagation outcomes. Shoot tip explants (2–3 mm)—derived from protocorm-like bodies were cultured on a regeneration medium containing Hyponex (20:20:20 and 6.5:6.5:19), 18 g/L sugar, 2 g/L peptone, 0.8 g/L activated charcoal, 12.5 g/L potato extract, 50 mL/L apple juice, and 10 mg/L 6-benzylaminopurine (6-BA), with… More >

Abstract This study investigates laminar convection in three regimes (forced convection, mixed convection, and natural convection) of a bi-nanofluid (Cu-Al₂O₃-water)/mono-nanofluid (Al₂O₃-water) inside a square enclosure of sliding vertical walls which are kept at cold temperature and moving up, down, or in opposite directions. The enclosure bottom is heated partially by a central heat source of various sizes while the horizontal walls are considered adiabatic. The thermal conductivity and dynamic viscosity are dependent on temperature and nanoparticle size. The conservation equations are implemented in the solver ANSYS R2 (2020). The numerical predictions are successfully validated by comparison with… More >

Abstract Background: Silica nanoparticles (SiNPs), commonly utilized in industrial and biomedical fields, are known to provoke pulmonary inflammation by elevating cyclooxygenase-2 (COX-2) levels in human pulmonary alveolar epithelial cells (HPAEpiCs). Salvianolic acid A (SAA), a water-soluble polyphenol extracted from Salvia miltiorrhiza (Danshen), possesses well-documented antioxidant and anti-inflammatory activities. Nevertheless, its potential to counteract SiNP-induced inflammatory responses in the lung has not been thoroughly explored. Objective: This study aimed to evaluate the protective role and mechanistic actions of SAA against SiNP-triggered inflammation in both cellular and animal models. Methods: HPAEpiCs were pre-incubated with SAA prior to SiNP exposure to… More >

Abstract The main objective of the study was to prepare a highly active antimicrobial remedy by combining active agents such as tannic acid and silver nanoparticles, which are usually used separately. This was achieved by applying a coating of 11 alternating layers of an insoluble complex of tannic acid with polyvinyl alcohol on paper by the layer-by-layer approach, on the surface of which uniformly distributed spherical silver nanoparticles of uniform size, mainly 20–30 nm, were synthesized by in situ reduction using tannic acid, which also acts as a stabilizer, or an external reducing agent, which prevented polyphenol More > Graphic Abstract
