in the current study, whey protein- pullulan- clay nanocomposite films are prepared by casting method. the effect of nanoclay at three concentrations (1%, 3% and 5%) on physical properties such as moisture content, solubility in water, water vapor permeability and transparency of whey protein- pullulan composite films investigated. the results show that the effect of nanoparticles on composite ...

Posidonia oceanica biomass has been valorized to produce cellulosic nanocrystals with different purification degrees at lab- and pilot plant-scale. The (10 % 20 (w/w)) were incorporated into corn starch, producing biocomposite films by melt mixing hot-pressing lab-scale. Biocomposite showed remarkable improvements on the mechanical water barrier performance (up 10-fold increase in elastic modul...

Kenaf is a nonwoody fibrous plant, and its fibre can be potentially used as reinforcement in the matrix to produce biocomposite materials. The properties of materials are highly dependent on reinforcing material binder. This study kenaf with different compositions (10, 20, 30 wt.%) lengths (1 cm 3 cm) using casting process. Low viscosity epoxy resin (635 thin resin) 6 poise was matrix. results ...

The Piptadeniastrum Africanum bark tannin extract was characterized using MALDI TOF, ATR-FT MIR. It used in the development of a resin with Vachellia nilotica as biohardener. This is consisting Catechin, Quercetin, Chalcone, Gallocatechin, Epigallocatechin gallate, Epicatechin gallate. gel time at natural pH (pH = 5.4) 660 s and its MOE obtained by thermomechanical analysis 3909 MPa. tenacity U...

In the past, the two major biomineralization motifs, biosilicification and biocalcification, were considered as two discrete processes. However, there is increasing evidence of the existence of an inextricable relationship between biosilica and calcium-based biominerals. The recent discovery of a unique silica–chitin–aragonite biocomposite in one genus of demosponges (Verongida) introduces a no...
