Novel, functional materials based on chitin of marine origin and lignin were prepared. The synthesized subjected to physicochemical, dispersive-morphological electrokinetic analysis. results confirm the effectiveness proposed method synthesis chitin/lignin materials. Mechanism modification by is formation hydrogen bonds between lignin. Additionally, studied from perspective waste water treatment. synthetic presented in this work shows an attractive facile route for producing low-cost...
The characteristic mineral-free fibrous skeletons (made of structural protein-spongin) <italic>H. communis</italic> (Demospongiae: Porifera) was used as a template in hydrothermal synthesis hematite (α-Fe<sub>2</sub>O<sub>3</sub>) nanoparticles.
Chitin of poriferan origin is a unique and thermostable biological material. It also represents an example renewable materials source due to the high regeneration ability Aplysina sponges under marine ranching conditions. Chitinous scaffolds isolated from skeleton sponge aerophoba were used as template for in vitro formation Fe2O3 conditions (pH ∼ 1.5, 90 °C) which are extreme materials. Novel chitin–Fe2O3 three dimensional composites, have been prepared first time using hydrothermal...
Multifunctional chitin/lignin materials were synthesized. In order to combine mechanical milling of the biopolymers with simultaneous mixing, a centrifugal ball mill was utilized. The resulting materials, differing in terms proportions precursors used, underwent detailed physicochemical and dispersive‐morphological analysis. On basis FT‐IR spectra results elemental analysis, efficiency preparation determined. influence on thermal stability systems also evaluated. Zeta potential determined as...
During the winter months of 2020/2021 a wave multisystem inflammatory syndrome in children (MIS-C) emerged Poland. We present results nationwide register aiming to capture and characterise MIS-C with focus on severity determinants. The first Poland was notably high, hence our analysis involved 274 children. group 62.8% boys, median age 8.8 years. Besides one Asian, all were White. Overall, disease course not as severe previous reports, however. Pediatric intensive care treatment required for...
C.I. Natural Red 4 dye, also known as carmine or cochineal, was adsorbed onto the surface of spongin-based fibrous skeleton Hippospongia communis marine demosponge for first time. The influence initial concentration contact time, and pH solution on adsorption process investigated. results presented here confirm effectiveness proposed method developing a novel dye/biopolymer hybrid material. kinetics sponge were determined. experimental data correspond directly to pseudo-second-order model...
The aim of extreme biomimetics is to design a bridge between biomineralization and bioinspired materials chemistry, where the basic principle exploit chemically thermally stable, renewable biopolymers for development next generation biologically inspired advanced functional composite materials. This study reports first time use proteinaceous spongin-based scaffolds isolated from marine demosponge Hippospongia communis as three-dimensional (3D) template hydrothermal deposition crystalline...
Hydroxyapatite (HAp)/chitosan (CS) composites were synthesized via a one-step co- precipitation method from aqueous solution, with the use of calcium chloride (CaCl2) and disodium hydrogen phosphate (Na2HPO4). CS was obtained partial deacetylation chitin strong sodium hydroxide solution. Composites prepared various HAp/CS ratios (30/70, 50/50, 70/30, 85/15) for comprehensive comparison their properties. Fourier Transform Infrared Spectroscopy (FT- IR) analysis showed that bonds formed...
Abstract The research reported here concerns the synthesis, characterization and potential applications of silica/lignosulfonate hybrid materials. Three types silica were used (Aerosil®200, Syloid®244 hydrated silica), along with magnesium lignosulfonate. effectiveness material synthesis methodology was confirmed indirectly, using Fourier transform infrared spectroscopy, elemental colorimetric analysis. Dispersive-morphological analysis indicates that products best properties obtained 10...
Abstract Chitin originating from marine sponges possesses a unique nanofibrillar network structure that is the basic element of microtubular scaffold-like skeleton these organisms. Sponge chitin represents an intriguing example thermostability, as it stable up to 400 °C. It also constitutes renewable biological source due high regeneration ability Aplysina under farming conditions. These properties can be exploited for facile and environmentally friendly creation novel, biocompatible...
Abstract We demonstrate here that lignin can be successfully combined with silica to create a multifunctional material considerable sorption capabilities. Experiments were carried out in which silica/lignin hybrid was used for the removal of lead(II) ions from water solutions. Adsorption kinetics also determined and preliminary regeneration tests performed. The effectiveness adsorption process depends on following parameters: contact time adsorbent adsorbate (equilibrium times: 5 min...
Multisystem inflammatory syndrome in children (MIS-C) is the result of an immune response triggered by a previous exposure to SARS-CoV-2. The clinical presentation MIS-C overlaps with other life-threatening bacterial infections, which antimicrobials are mainstay therapy. aim study was describe use antibiotics Poland.The analysis 345 reported from 42 Polish cities national MultiOrgan Inflammatory Syndromes COVID-19 Related Study (MOIS-CoR Study) June 2020 April 2021.At least one antibiotic...
<p>Functional hybrid materials based on magnesium lignosulfonate and silica were obtained characterized. Magnesium is a common waste product of the wood pulp industry, while well-known inorganic material with exceptional physicochemical properties. In this study, silicas spherical particle shape synthesized using sol-gel method alternatively in nonpolar medium. Silica was found to improve thermal electrokinetic properties final products.
