Abstract:

Polysaccharides constitute an important class of biopolymers. They usually display biocompatibility and biodegradability, which are the basic characteristics for polymers used as biomaterials, and some of them exhibit unique physical and/or biological properties. We would like to report here new strategies for the chemical modification of water-soluble polysaccharides, such as hyaluronic acid (HA) and carboxymethylcellulose (CMC), providing access to smart hydrogels and nanogels (hydrogels confined to submicrometric dimensions) for drug/cell delivery. Using thiol-ene reactions, we successfully grafted thermosensitive ethylene-glycol based copolymers on HA, allowing temperature-triggered assembly of the polysaccharide into nanogels with diameters < 200 nm. These gel particles possess many interesting features for drug delivery, like: facile formation, tunable size and stability, easy loading of hydrophobic molecules, high selectivity and binding affinity for cancer cells expressing the CD44 receptor of HA, degradation behavior due to the inherent biodegradability of HA. In addition, after intraveneous injection in mice, they were shown to enter the blood circulation. Thiol-ene reactions were also applied to engineer macrogels of HA and CMC. We showed the ability to obtain self-healing hydrogels in physiological conditions by the careful design of HA modified with phenylboronic acid and sugar derivatives. Moreover, by combining lipid nanoparticles (LNPs) and carboxymethylcellulose (CMC) hydrogels, we developed original hybrid biomaterials that are able to provide local delivery of hydrophobic therapeutic agents in a predictable and sustained manner. These new delivery systems offer promising platforms for the controlled release of various drugs under certain external stimuli (mechanical stress, light irradiation, etc.).

Abstract:

Textile mill, the largest revenue earning industry in Bangladesh is facing problem with the disposal of its solid waste (sludge). In this study, textile sludge is detoxified with gamma irradiation (15 kGy) and then used to make environmental friendly bricks for construction purposes. Bricks were graded based on the sludge and clay content ratio. Sludge was mixed with clay and bricks were made in wooden frame. Dried brick samples were then kept at 450°C for 24 hours in furnace. Controlling the temperature allowed us to produce the brick without producing any NOx. Parameters such as density (g/cm³), weight loss (%), firing shrinkage (%),bending strength (MPa), , Bending modules (MPa), Impact strength (kJ/m²), water uptake (%) and electrical resistivity (Ω-m) were investigated. Density, weight loss, firing shrinkage and electrical resistivity reduced as sludge content (%) in bricks increased whereas bending strength, Bending modules, Impact strength and water uptake (%) increased with the increase of sludge content. The optimum results were found for the 50-50% sludge/clay samples. Further increase in the sludge percentage led to loss of strength and compactness of the brick sample. According to the results, the optimum sample showed higher strength than the sample made by pure clay; but showed slightly lower strength than the commercial brick. The change in density of all bricks was experienced during the aging tests in water, acid, alkali and salt. bending strength, Bending modules, Impact strength were also tested for water and acid aging. Morphological analysis of the brick samples were done by metallurgical inverted microscope.
