Abstract Biodegradable nanoparticles such as chitosan nanoparticles (CSNPs) are used in sustainable agriculture since they avoid damage to the environment; CSNPs have positive effects such as the accumulation of bioactive compounds and increased productivity in plants. This study aimed to investigate the impact of applying CSNPs on lettuce, specifically focusing on enzymatic activity, bioactive compounds, and yield. The trial was conducted using a completely randomized design, incorporating CSNPs: 0, 0.05, 0.1, 0.2, 0.4, and 0.8 mg mL. The doses of 0.4 mg mL improve yields up to 24.6% increases and 0.1 mg mL of CSNPs increases More >

Abstract Background: Glioblastoma multiforme (GBM) is recognized as the most lethal and most highly invasive tumor. The high likelihood of treatment failure arises from the presence of the blood-brain barrier (BBB) and stem cells around GBM, which avert the entry of chemotherapeutic drugs into the tumor mass. Objective: Recently, several researchers have designed novel nanocarrier systems like liposomes, dendrimers, metallic nanoparticles, nanodiamonds, and nanorobot approaches, allowing drugs to infiltrate the BBB more efficiently, opening up innovative avenues to prevail over therapy problems and radiation therapy. Methods: Relevant literature for this manuscript has been collected from a comprehensive More > Graphic Abstract

Abstract The study focuses on the development of biocompatible and stable FA-functionalized nanocrystalline cellulose (NCC) as a potential drug delivery system for targeting folate receptor-positive cancer cells. The FA-functionalized NCCs were synthesized through a series of chemical reactions, resulting in nanoparticles with favorable properties for biomedical applications. The microstructural analysis revealed that the functionalized NCCs maintained their rod-shaped morphology and displayed hydrodynamic diameters suitable for evading the mononuclear phagocytic system while being large enough to target tumor tissues. Importantly, these nanoparticles possessed a negative surface charge, enhancing their stability and repelling potential aggregation. The binding specificity… More > Graphic Abstract

Abstract The influence of Brownian motion and thermophoresis on a fluid containing nanoparticles flowing over a stretchable cylinder is examined. The classical Navier-Stokes equations are considered in a porous frame. In addition, the Lorentz force is taken into account. The controlling coupled nonlinear partial differential equations are transformed into a system of first order ordinary differential equations by means of a similarity transformation. The resulting system of equations is solved by employing a shooting approach properly implemented in MATLAB. The evolution of the boundary layer and the growing velocity is shown graphically together with the related More >

Abstract Sintered silver nanoparticles (AgNPs) are widely used in high-power electronics due to their exceptional properties. However, the material reliability is significantly affected by various microscopic defects. In this work, the three primary micro-defect types at potential stress concentrations in sintered AgNPs are identified, categorized, and quantified. Molecular dynamics (MD) simulations are employed to observe the failure evolution of different microscopic defects. The dominant mechanisms responsible for this evolution are dislocation nucleation and dislocation motion. At the same time, this paper clarifies the quantitative relationship between the tensile strain amount and the failure mechanism transitions of More >

Abstract Friction and wear phenomenon is a complex nonlinear system, and it is also a significant problem in the process of metal cutting. In order to systematically analyze the friction and wear process of tool material-workpiece material friction pair in the cutting process of high hardness alloy steel under different lubrication conditions, the chaotic characteristics of friction process between high hardness alloy steel and cemented carbide under the lubrication C60 nano-particles fluid are studied based on the chaos theory. Firstly, the friction and wear experiments of the friction pair between high hardness alloy steel and cemented… More >

Abstract In current work, Nanoparticles of cadmium zinc sulfide (CdZnS) and copper zinc sulfide (Cu:CdZnS) were synthesized through a capping-agent-free chemical co-precipitation method. This article focuses on the optical characteristics, elemental analysis, and surface morphology of CdZnS and Cu:CdZnS. this properties of prepared materials were investigated using a variety of techniques, including X-ray diffraction (XRD), scanning electron microscopy, energy dispersive X-ray, and ultraviolet–visible absorption. The results show both pure and doped CdZnS have cubic structure. The energy gap of CdZnS was equal to 3.14 eV and 3.4 eV for Cu doped CdZnS. According to the results More >

Abstract The characterizations of synthesized CdZnS nanoparticles with Clitoria ternatea (Asian pigeon wings) leaf extract were done by the chemical precipitation method. The formation of CdZnS nanoparticles with the extract was confirmed by making use of XRD, SEM analysis and EDAX. XRD disclosed the structure and also the particle size. SEM investigation of CdZnS NPs confirmed shape and size. The optical studies were executed for the prepared sample. From the obtained UV-visible spectrum, band gap energy was determined using the Tauc plot. The photocatalytic activity of the processed sample was also analysed. More >

Abstract ZnS and Er (2 at%) doped ZnS nanoparticles (NPs) were synthesized through coprecipitation process. EDAX analysis confirmed that the presence of Er (III) ions in the prepared sample with an anticipated stoichiometry. TEM analyses displayed that the prepared NPs showed near spheroid shapes with an average size ranging from 4.8 to 5.2 nm. XRD measurements confirmed the authentic incorporation of Er (III) ions in the ZnS lattice. DRS measurements certified that Er (III) doping declines the ZnS bandgap from 3.72 to 3.56 eV. Magnetic measurements revealed that the Er-doped ZnS NPs displayed soft ferromagnetism and More >
