This study is aimed to investigate the effect of simultaneous incorporation cellulose nanocrystals (CNC) and silver nanoparticles (SN) on mechanical, biodegradability, water vapor permeability polylactic acid (PLA)-based films. PLA films their nanocomposites containing different levels CNC (0.333, 1 1.667 phr) SN (0.333 were prepared by solution casting method. was reacted with acetic anhydride...
BACKGROUND Liposomes are currently an important part of biological, pharmaceutical, medical and nutritional research, as they are considered to be among the most effective carriers for the introduction of various types of bioactive agents into target cells. SCOPE OF REVIEW In this work, we study the lipid organization and mechanical properties of biomembranes made of marine and plant phosphol...
kefiran is an exopolysaccharide produced by microorganisms present in the kefir grains that has several health promoting properties. in this research, physico-mechanical and thermal characteristics of nanocomposite film composed of kefiran-montmorillonite (mmt; 1, 3 and 5% w/w) were studied. results showed that the thickness and the tensile strength of the films increased by increasing the nano...
Worldwide, it is now known that industrial by-products rich in silicon (Si) and aluminum (Al) can be transformed by alkaline activation into so-called “green concrete”, an efficient sustainable material the field of construction; geopolymer material. In this work, materials produced using fly ash marble dust or blast furnace slag were studied to assess influence these substitutions on performan...
