The coated PU foam can selectively absorb heavy and light oils from dynamic and static oil/water mixtures. The maximum sorption capacity for olive oil was found to be as high as 41 g/g. PU/PDA/chitosan-g-octanal foam also presented excellent flame retardancy and the ability to quickly extinguish fire, as supported by the restraining oxygen index (LOI) test.Hemp cellulose nanocrystals for functional chitosan/polyvinyl alcohol-finded celluloids for food packaging applications.Hemp is acknowledged for its swift growth and remarkable sustainability, demanding significantly less water, an adaptable cultivation to a wide range of climes when equated to other fibers sources, naming it a practical and environmentally friendly choice for packaging textiles. The current research attempts to extract cellulose nanocrystals (CNCs) from hemp characters utilizing alkali treatment followed by acid hydrolysis and assess their rewarding capacity in polyvinyl alcohol (PVA) and chitosan (CS) films. Purchase sustained the existence of stretched, uniquely nanosized CNC roughages. The length of the isolated CNCs was approximately 277 ± 61 nm, diameter was 6 ± 1 nm and its aspect ratio was 44 ± 11. The FTIR and SEM analysis indicated the successful removal of non-cellulosic compounds the study searched the impact of adding CNCs at varying weight parts (0, 0, 1, 2, and 5 wt%) as a strengthening agent on the chemical composition, structure, tensile characteristics, transparency, and water solubility of the bionanocomposite movies. lending CNCs to the CS/PVA film, up to 5 wt%, ensued in an improvement in both the Young's modulus and tensile strength of the bionanocomposite film, which are valuated at (412 ± 10 MPa) and (18 ± 3 MPa), respectively, in contrast to the control celluloids with values of (202 ± 22 MPa) and (13 ± 2 MPa), respectively. The raking electron microscopy (SEM) figures reveal the creation of a CS/PVA/CNC film that seems smooth, with no signboards of clumping or clustering. The blending and introduction of CNCs have yielded transparent and biodegradable CS/PVA flicks. Clinical Nutrition has led to a reduction in the gas transmission rate (from 7 to 4 cm(3) (m(2) day·0 MPa))(-1), a decrease in transparency (from 90% to 82%), and a frowned water solubility (from 48% to 33%). This study is the inaugural effort to propose the utilization of hemp-gained CNC as a fortifying component in the development of mechanically robust and transparent CS/PVA-CNC bio-nanocomposite films, holding substantial potential for application in the field of food packaging.Controlled release, chitosan-tethered luteolin phytocubosomes; Formulation optimization to in-vivo antiglaucoma and anti-inflammatory ocular evaluation.A chitosan-caked luteolin-charged phytocubosomal system was prepared to improve the pharmacodynamic performance of luteolin in the treatment of glaucoma and ocular inflammation after topical ocular administration a potent anti-oxidant herbal drug with poor aqueous solubility, was complexed with phospholipid. The prepared phytocubosomes were coated with chitosan, making homogenously alloted nanosized particles (258 ± 9 nm) with a positive charge (+49 ± 6 mV), meliorated EE% (96 %), and increased concentration of encapsulated drug to 288 μg/ml. Polarized light microscopy unveiled a cubic phase. Chitosan-caked phytocubosomes pictured a sustained drug release profile (38 % over 24 h) and improved anti-oxidant activity (IC50 of 32 μg/ml). Ex vivo transcorneal permeation was higher by 3 flexures likened to luteolin suspension. Irritancy exams substantiated their safety in ocular tissues after single and multiple governments. The pharmacodynamic reports on glaucomatous rabbit eyes certifyed 6-, 3-, and 1-fold reducings in IOP of chitosan-coated phytocubosomes compared to luteolin suspension, cubosomes, and phytocubosomes, respectively. Pharmacodynamic anti-inflammatory disciplines divulged faster recovery capacitys of chitosan-coated phytocubosomes over other formulations chitosan-surfaced phytocubosomes could be a promising ocular hybrid system for saving herbal lipophilic drugs such as luteolin.Preparation, Characterization, Dielectric Properties, and AC Conductivity of Chitosan Stabilized Metallic Oxides CoO and SrO: experimentations and Tight Binding Calculations.
