The characterization and analysis of the cementation properties novel biopolymer binders in soils are essential for their potential application geotechnical engineering. This study investigates effect a zein binder on sandy soils. Soil specimens mixed with various contents ranging from 0 to 5%. mechanical microscopic characteristics treated evaluated using unconfined compression tests scanning ...

the aim of the present work was to prepare and characterize biopolymer nanocarriers and evaluate their suitability in possible oral delivery of insulin. the egg albumin biopolymer was used to prepare nanoparticles which were further characterized by fourier transformed infrared spectroscopy (ftir), transmission electron microscopy (tem), scanning electron microscopy (sem), zeta potential, dynam...

Collagen gels are widely used in experiments on cell mechanics because they mimic the extracellular matrix in physiological conditions. Collagen gels are often characterized by their bulk rheology; however, variations in the collagen fiber microstructure and cell adhesion forces cause the mechanical properties to be inhomogeneous at the cellular scale. We study the mechanics of type I collagen ...

We examine pressure-driven nonequilibrium transport of linear, circular, and star polymers through a nanochannel containing a rectangular pit with full hydrodynamic interactions and thermal fluctuations. We demonstrate that with sufficiently small pressure differences, there is contour length-dependent entropic trapping of the polymer in the pit when the pit and the polymer sizes are compatible...

Chitosan is typically obtained by deacetylation of chitin under alkaline conditions, which is one of the most abundant organic materials, being second only to cellulose in the amount produced annually by biosynthesis. Chitosan is a linear polysaccharide, composed of glucosamine and Nacetyl glucosamine units linked by (1–4) glycoside bonds. The content of glucosamine is called the degree of deac...

Novel drum-like Cd(OH)(2) superstructures with uniform size were synthesized on a large scale through a facile one-pot hydrothermal route with the co-existence of ammonia and biopolymer sodium carboxymethyl cellulose solutions.

UNLABELLED BACKGROUND A natural carbohydrate biopolymer was extracted from the agricultural biomass waste (durian seed). Subsequently, the crude biopolymer was purified by using the saturated barium hydroxide to minimize the impurities. Finally, the effect of different drying techniques on the flow characteristics and functional properties of the purified biopolymer was investigated. The pre...

The industrial implementation of costand eco-efficient production of bio-based polymeric materials such as polyhydroxyalkanoates (PHAs) or polylactic acid (PLA) requires the comprehension of all process steps. The article at hand provides an insight into recent advances in allocation, pretreatment and utilization of raw materials available for biopolymer production in different areas of the wor...
