Abstract Background Access to water and sanitation is a basic human right; however, in many parts of the world, communities experience water, sanitation, hygiene (WaSH) insecurity. While WaSH insecurity prevalent low middle-income countries, it also problem high-income like United States, as evident vulnerable populations, including people experiencing homelessness. Limited knowledge exists about coping strategies unhoused use access services. This study, therefore, examines among Los...
Nowadays, poly (vinyl alcohol) (PVA) hydrogels are being studied for several biomedical applications such as joint replacement, wound dressings and controlled drug-releasing devices, among others. Reinforced PVA show good mechanical properties a suitable option to replace cartilages. Furthermore, these materials can prevent loss of body fluids, be barrier against bacteria also permeable oxygen, all interesting properties, they used like dressings. For drug delivery systems material that...
Abstract Chitosan and pectin are employed here in the formation of biodegradable hydrogels. The addition cellulose nanowhiskers (CNW) into hydrogels is accomplished through two methods: by swelling, after polymeric network (Method A), inclusion polymer solutions before gelation, with varying CNW content B). Comprehensive physico–chemical, thermal, microscopic, gel fraction, water vapor transmission analyses conducted, complemented antibacterial viability assessments. CNWs successfully...
This work presents the development of eco-friendly ferrogel beads that can effectively remove emerging pollutant diclofenac (DFC) from wastewater. These are composed natural polysaccharide/iron oxide. The structure and properties were studied using various techniques. Scanning electron microscopy images revealed porosity nature hydrogel due to incorporation magnetic nanoparticles (MNPs). TEM indicates diameter size MNPs around 8.3 ± 2 nm. addition resulted in enhanced visible MNP...
Abstract Magnetic biomaterials were prepared using magnetite and chitosan‐coated nanoparticles ( CSNPs ) dispersed in poly(vinyl alcohol) gels. Two different methods developed to obtain ferrogels: situ co‐precipitation of (Ferro‐ IS by adding previously synthesized the neat matrix ). In both cases, crosslinking was carried out freezing − thawing (F‐T). The as‐prepared materials as well precursor characterized Fourier transform infrared spectroscopy, electronic microscopy (scanning...
Polyvinyl alcohol (PVA) and polyvinyl alcohol-pectin (PVA-P) cryogels are potential devices for wound healing. These materials have advantages over commercial dressings such as: retaining an appropriate level of moisture around gas permeability antibacterial properties. In a previous work, PVA-P containingan antibiotic enzyme (enrofloxacin keratinase respectively) been developed with promising results. the present exhaustive chemical, morphological physical characterization these films was...
Self-assembly of natural polymers constitute a powerful route for the development functional materials. In particular, layer-by-layer (LBL) assembly constitutes versatile technique nanostructuration biobased into multilayer films. Gelatin has gained much attention its abundance, biodegradability, and excellent gel-forming properties. However, gelatin gels melt at low temperature, thus limiting practical application. With respect to above considerations, here, we explored potential...
Cosmetotextiles are novel textiles which contain carriers with active and cosmetic substances, these carriers, generally by polymeric nature, release their compounds when in contact the human body.The aim of this mini review work is to report new developments textiles, focusing obtaining microcapsules containing skin care physically or chemically bound fiber surface.The selection encapsulation technique shell material depends on final application product, considering physical chemical...
Ferrogels with well-dispersed single-domain magnetic nanoparticles (NPs) were obtained by the infusion of iron salts in physically cross-linked poly(vinyl alcohol) (PVA) hydrogels followed coprecipitation. Freeze–thaw (F–T) cycling was used as a cryogenic technique to form mechanically strong and highly swellable hydrogels. The networked structure final material constrained environment for precipitation oxide NPs formation gel. A homogeneous, ensemble more than 15 wt % (in only one cycle...
