This study validated the utility of HAPS for directly admitted patients with AP in India. Large-scale multicenter community-based studies need to be performed.
The current investigation reports in situ fabrication of hyperbranched polyurethane (HPU) nanocomposites with different weight percentages of functionalized silica nanoparticle as nano-reinforcing material. Silica nanoparticles were functionalized with sodium dodecyl sulfate and polyethylene glycol using a facile, simple one-pot method. The nanomaterial and the HPU nanocomposites were assessed by Fourier Transform Infrared Spectroscopy (FTIR), Ultraviolet (UV)-visible, X-ray Diffraction (XRD), Transmission Electron Microscope (TEM), mechanical and thermal studies. The fabricated nanocomposites demonstrated notable tensile strength (25.8 MPa), excellent elongation at break (1495%), outstanding toughness (340.88 MJ•m -3 ), good scratch hardness (7.5 kg), significant impact strength (19.02 kJ•m -1 ) and sufficient improvement in hydrophobicity (105.2° from 76.7°). They also demonstrated remarkable non-contact triggered thermo-responsive shaperecovery (97.6-99.4%). Moreover they displayed efficient self-healing behavior within just 20 s under microwave (360 W). The nanocomposites also exhibited biodegradation by bacterial strains, Pseudomonas aeruginosa, and Bacillus subtilis. Thus, the present work promotes this biodegradable nanocomposite as a potential high performing self-healing and selfcleaning material.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
