Editorial: Biodegradable Materials
This Special Issue "Biodegradable Materials" features research and review papers concerning recent advances on the development, synthesis, testing and characterisation of biomaterials. These biomaterials, derived from natural and renewable sources, offer a potential alternative to existing non-biodegradable materials with application to the food and biomedical industries amongst many others. In...
متن کاملPreparation and evaluation of carvacrol pellets based on PVP solid-dispersion by extrusion-spheronization technique
Background and objectives: Carvacrol is one of the main pharmacologically active components of Thymus vulgaris essential oil which has shown several therapeutic effects. There are few works regarding the formulation of essential oils as oral solid dosage forms due to their liquid nature, stability and technical problems. The aim of this study was to combine the solid-d...
متن کاملPreparation of Biodegradable Low Density Polyethylene by Starch – Urea Composition for Agricultural Applications
It has been proven that polyolefins specially low density polyethylene (LDPE), are resistant against degradation and microorganism attacks; Thus, one of the most important properties of industrial plastics, is their environmental biodegradability. Since plastics are being widely used in agriculture, horticulture and packaging, meeting this requirement becomes increasingly dificult (speciall...
متن کاملPreparation of reactive surfaces by electrografting.
The electrografting process has been applied to a new monomer in order to induce reactivity to the surface of various conducting substrates which are then appropriate for the anchoring of a large variety of molecules (catalysts, proteins, amino-polymers etc.).
متن کاملChemical Modification of Polysaccharides Using Reactive Extrusion
Sodium carboxymethyl starch (CMS) was prepared using an extruder as a continuous solvent-less chemical reactor. The effects of NaOH, H2O, temperature, ethanol, sodium mono chloro acetate (SMCA), sodium tripolyphosphate (STPP), citric acid, epichlorohydrin and screw configuration on the degree of substitution (DS) and swelling properties of CMS were studied. Using these factors, CMS with the DS ...
