Abstract Corrosion and its protection are one of the major challenges that faced by industries. To overcome this, new coatings with characteristic properties which environmentally friendly introduced. A cost-effective most reliable way corrosion is via barrier coatings, in water-based epoxy showed significant resistance. Although coating creates a between metal corroding ions, there chance leak...

Abstract Phase change materials (PCMs) possess remarkable capability to store and release substantial amounts of energy during the processes melting crystallization across a wide temperature range, thus holding great promise in applications related regulation thermal storage. Herein, effectively address PCM leakage enhance conduction, microcapsules with melamine–formaldehyde resin (MF) shell we...

the use of bacteriocins, mainly nisin, is one of the most significant preservation technologies in the food industry. nisin encapsulation can improve stability and homogenous distribution in food matrices. in this study, liposomes of four various lipids (lipoid s 100, lipoid s pc-3, lipoid s pc, and lipoid pc (dppc)) were prepared by dehydration-rehydration method, and compared for entrapment e...

background :  kefir contains lactic acid bacteria ( lactobacillus , lactococcus , leuconostoc , acetobacter and streptococcus ) and yeasts ( kluyveromyces , torula , candida , and saccharomyces ). kefiran is the polysaccharide produced by lactic acid bacteria in kefir.   methods :  kefiran was prepared from milk containing 0.5% fat and 10 grams kefir grains and was separated from kefir by ethan...

A novel negatively thermo-sensitive and biodegradable microgel was prepared by combination of macromer synthesis and inverse suspension polymerization. A new post-fabrication encapsulation technique based upon this kind of intelligent microgel was developed. Model proteins (hemoglobin, bovine serum albumin and insulin) were encapsulated into the microgels at 4 degrees C and released in vitro at...

Research regarding the effects of encapsulation on soldier performance is critical for achieving effective mission performance as well as the survivability capabilities of dismounted soldiers of the Future Force. Soldier encapsulation is defined as enclosing the soldier’s body in such a manner that all skin is protected from exposure to the elements of the battlefield. The objective of this res...

the purpose of this study was to optimize a method for the encapsulation of p5 peptide, a new designed peptide containing mhc class i epitopes from rat her2/neu protein, into liposomes as an approach for breast cancer vaccine formulation. the efficiency of liposomal encapsulation of peptides is generally low and development of an optimized method to increase encapsulation efficiency is a big ch...

combination formulations of liposomes with collagen have been previously introduced as a means of obtaining more stable and less permeable liposomes. in this study, the effect of aqueous solutions of the collagen products collapur? (col) and collapuron-dak? (cold) from henkle co., on the release rate of sodium chromate (chr) as a water-soluble model drug from stable plurilamellar vesicles (splv...

conclusions b. subtilis entrapped in beads was able to preserve its viability and produce biosurfactants as secondary metabolites. therefore, this method could be applied as a continuous culture system of biosurfactant production. methods alginate and bacterial solutions were mixed by stirring to obtain a uniform mixture and added by drops into cacl2 solution to form spherical beads. the spheri...
