• Natural fibres decreases the dry density of earth extrudates. compressive strength increases ductility and Xanthan gum improves interface quality between natural fibres. Diss surface roughness provides interesting reinforcing effects. This paper deals with development sustainable building earth-based materials. More precisely, it addresses study reinforcement raw originated from Algeria (diss...

Biopolymer nanotubes (BNTs) are two-open ended cylindrical structures which can be used for nanodevices, medicine, and biology. Especially, fabricating BNTs using proteins is suitable for biological and biomedical applications due to their safety and biocompatibility. This study has been focused on fabricating BNTs using polysaccharides which have been proved to be safe by the FDA and used in f...

introduction: in recent years, sugar-free or reduced-sugar foods and beverages are becoming very popular among the consumers. at the same time, consumers are increasingly concerned about the quality and safety of many products present in the diet, in particular, low-calorie synthetic or natural sweeteners. sugar adds viscosity and provides body in drinks and semi-liquid foods like syrups and fr...

Xanthan gum is a water-soluble polysaccharide obtained by fermentation of the genus Xanthomonas with several properties, such as low-cost, biodegradability, biocompatibility and non-toxicity. However, an important limitation xanthan gum-based biomaterials high swelling degree in solvent mechanical weakness, which results biomaterial disintegration. For this reason, aim work was to develop hydro...

Magnetic biosensors are an important part of biomedical applications of magnetic materials. As the living tissue is basically a "soft matter." this study addresses the development of ferrogels (FG) with micron sized magnetic particles of magnetite and strontium hexaferrite mimicking the living tissue. The basic composition of the FG comprised the polymeric network of polyacrylamide, synthesized...

The seasonal biological drawdown of the partial pressure of CO2 (pCO2) in the surface waters of the Oyashio region of the western subarctic Pacific is one of the greatest among the world’s oceans. This is attributable to spring diatom blooms. Transparent exopolymer particles (TEPs) are known to affect efficiency of the biological carbon pump, and higher TEP levels are frequently associated with...
