The objective of this investigation was to evaluate the influence micro- and nanoplastic particles composed polyethylene terephthalate (PET), a significant contributor plastic pollution, on human brain vascular pericytes. Specifically, we delved into their impact mitochondrial functionality, oxidative stress, expression genes associated with ferroptosis functions. Our findings demonstrate that exposure monoculture pericytes PET in vitro at concentration 50 μg/ml for duration 3, 6 10 days did...
An experimental investigation is reported on the effect of shear bursting molten ultra-thin polymer films embedded in an immiscible matrix. By using optical microscope coupled with a shearing hotstage, dewetting dynamics, i.e. growth holes monitored over time at various rates. It observed that their circularity modified by and for all temperatures thicknesses studied, speed formed rapidly increases increasing rate. A model balancing capillary forces viscous dissipation while taking into...
The measurement of interfacial mechanical or rheological properties in polymer blends is a challenging task, as well providing quantitative link between these and the nanostructure. Here, we perform systematic study extensional rheology multilayer films an immiscible pair, polystyrene poly(methyl methacrylate). We take advantage multi-nanolayer coextrusion to increase number interfaces up thousands, consequently magnifying response films. transient elongational compared additivity rule model...
Carbon-carbon (C-C) composites are highly sought-after in aviation, automotive, and defense sectors due to their outstanding thermal thermo-mechanical properties. These valued for exceptional properties, including remarkably low density coefficient of expansion, which expected surpass those many alloys other the production high-grade components. However, current manufacturing methods C-C unable meet market demands high cost, speed, labor-intensive processes, limiting broader applications....
In this work, zinc oxide particles (ZnO NPs) green synthesis with the application of black tea extract (BT) is presented. A thorough investigation properties and obtained materials was conducted by using Fourier transform infrared spectroscopy (FTIR), liquid chromatography-mass spectrometry (LC-MS), X-ray diffraction (XRD), scanning electron microscopy (SEM), thermogravimetric analysis (TGA), quadrupole mass (QMS). The results indicated that amount used BT strongly influenced morphology,...
Coal, a crucial natural resource traditionally employed for generating carbon-rich materials and powering global industries, has faced escalating scrutiny due to its adverse environmental impacts outweighing utility in the contemporary world. In response worldwide shift toward sustainability, United States alone witnessed an approximate 50% reduction coal consumption. Nevertheless, ample availability of spurred interest identifying alternative sustainable applications. This research delves...
Carbon–carbon (C–C) composites are highly sought-after in aviation, automotive, and defense sectors due to their outstanding thermal & thermo-mechanical properties even surpassing those of alloys other for exterme operations.
The rheology of coextruded layered films polystyrene/poly(methyl methacrylate) (PS/PMMA) has been studied with small and large amplitude oscillations at a temperature above their glass transition. While the complex viscosity remains constant over experimental time window for micron-sized films, decrease observed nanolayered films. rheological behavior then correlated to morphological evolution multilayer films: while nanolayers dewet. Layer breakup followed by retraction coalescence leading...
Abstract The objective of this investigation was to evaluate the influence micro- and nanoplastic particles composed polyethylene terephthalate (PET), a significant contributor plastic pollution, on human brain vascular pericytes. Specifically, we delved into their impact mitochondrial functionality, oxidative stress, expression genes associated with stress ferroptosis. Our findings demonstrate that exposure monoculture pericytes PET in vitro at concentration 50 ppm for duration 6 days did...
