Three-dimensional (3D) bio-printing is a revolutionary technology to reproduce a 3D functional living tissue scaffold in-vitro through controlled layer-by-layer deposition of biomaterials along with high precision positioning of cells. Due to its bio-compatibility, natural hydrogels are commonly considered as the scaffold material. However, the mechanical integrity of a hydrogel material, espec...

The volume required for the rheological characterization of fluids can beminimized by using micromechanical cantilevers as viscosity sensors. Here, a simplemeasurement tool for the characterization of sugar solutions is proposed. The sensorconsists of a micromechanical cantilever as used in an atomic force microscopy which isintegrated into a closed fluid handling system. Fluid properties are d...

The present review aims to give a closer look of hydrogels based on chitosan and poly (vinyl alcohol) and to discuss their potential biomedical applications in drug delivery system. Various investigations based on chitosan/poly (vinyl alcohol) carried out recently by researchers have been reported in this review. Moreover different chemical and physical crosslinking methods used for hydrogels f...

encapsulation of bioactive ingredient and production of nano carriers in order to food enrichment and production of functional food is one of the applications of nano technology in food science and pharmaceutical. nano carriers are produced using biopolymers (proteins and polysaccharids) or lipid based materials. in this research, production and characterization of pectin-casein nanocomplexes a...

Thermoplastic rubbers are materials that combine the characteristics of good processability of thermoplastics with the physical properties of vulcanized rubber. SEBS is a SBS which has been subjected to a hydrogenation process, through the polybutadiene chain is eliminated. This new rubber has a high resistance to environment, temperature, UV radiation, etc. without losing the properties of a t...

The rheology of disperse systems is an important processing parameter. Being able to characterize and manipulate the flow behavior of dispersions one can ensure their optimal performance. Waterborne automotive coatings, for example, should exhibit a distinct low-shear viscosity necessary to provide good leveling but to avoid sagging at the same time. Then, a strong degree of shear thinning is n...

A physical modeling of rheological objects is presented. Objects showing rheological nature involve foods and biological tissues yet no systematic approach to build their virtual objects is not established. In this article, we will construct 2D/3D virtual rheological objects.
