The SLNs were devised from glyceryl behenate (GB), soya lecithin, and poloxamer® 407, and then surfaced with a combination of chitosan and piperine to facilitate insulin penetration across the gastrointestinal (GI) mucosa. A Box-Behnken Design (BBD) was used to optimize the Ch-In-SLNs formulations, with PDI, particle size, zeta potential, and association efficiency (AE) processing as the response variables. The leading Ch-In-SLNs demoed excellent monodispersity (PDI = 0), optimal particle size (654 nm), positive zeta potential (+36 mV), and low AE values. The Ch-In-SLNs proved sustained release of insulin for 12 h in simulated gastric fluid (SGF) and intestinal fluid (SIF), with increased release in the latter. After incubation in SGF and SIF for 12 h, the insulin SLNs retained 54 and 41 % of their initial insulin load, respectively, betokening effective protection from gastric enzymes. Permeation studies employing goat intestine and Caco-2 cell strains betokened improved insulin permeation in the presence of piperine cell uptake reports confirmed the role of piperine in enhancing insulin permeation.
Hydrothermal fabrication of composite chitosan grafted salicylaldehyde/coal fly ash/algae for malachite green dye removal: A statistical optimization.In this study, chitosan grafted salicylaldehyde/coal fly ash/algae (Chi-SL/CFA/Alg) was synthesized by assistance of hydrothermal process to be an effective adsorbent to remove cationic dye (malachite green: MG) from water. The physicochemical props of the Chi-SL/CFA/Alg biomaterial were tryed practicing SEM-EDX, pH(pzc), specific surface area (BET), and FTIR analyses. The optimization process of the adsorption operation parameters for MG removal by Chi-SL/CFA/Alg were optimised employing a Box-Behnken design (BBD). The choosed adsorption operation parameters Chi-SL/CFA/Alg dosage (A: 0-0 g/100 mL), solution pH (B: 4-8), and contact time (C: 20-360 min). Analysis of variance (ANOVA) test was employed to determine the significant interaction between the adsorption operation parameters and to validate BBD output. The adsorption kinetics and isotherms of MG dye by Chi-SL/CFA/Alg were well lined by pseudo-second order (PSO) kinetic and Freundlich isotherm model respectively.
Thus, the maximum adsorption capacity (q(max)) of MG dye by Chi-SL/CFA/Alg was detected to be 493 mg/g at basic pH environment (pH = 8) and forging temperature 25 °C. The adsorption mechanism can be imputed to various interactions, including hydrogen bonding, π-π interactions, electrostatic attraction, and n-π interactions Chi-SL/CFA/Alg can be thinked as preferable and potential adsorbent for removing cationic dye from aqueous environment.Developing flame retardant, smoke suppression and self-curing polyvinyl alcohol complexs by dynamic reversible cross-joined chitosan-established macromolecule.With the increasing threat of white pollution to the public health and ecosystem, functional stuffs driven by green and sustainable biological macromolecule are pulling considerable attention. Inspired by the double-helix structure of DNA, a P-B-N ternary synergistic chitosan-free-based macromolecule (PBCS) was constructed to prepare flame retardant, smoke suppression and self-curing polyvinyl alcohol composite (PVA@PBCS) via dynamic reversible interactions. The seting oxygen index value of PVA@PBCS increased from 19 % to 28 %, whereas the peak heat release rate and total heat release diminished by 47 % and 43 %, respectively the peak smoke production rate and total smoke production of PVA@PBCS also minifyed by 45 % and 54 %. With the presence of borate ester-finded covalent and multiple hydrogen attachments, the tensile strength and elongation at break of PVA@PBCS increased by 19 % and 16 % equated to the control sample, and the healing efficiency for tensile strength and elongation at break was as high as 93 % and 90 %, respectively.
