the water content of the epidermis is a main factor in maintaining skin smoothness and elasticity and preventing skin dryness. occlusive products can greatly affect skin hydration by forming a barrier on the skin following the topical administration of oil-based formulations. these products repair the skin barrier by restoring the skin lipids as well. solid lipid nanoparticles (slns) have recen...

nowadays, nanoscale innovations in the forms of pathogen detection, active packaging, antimicrobial packaging and barrier formation are poised to elevate food packaging to new heights. antimicrobial nanocomposite ldpe films containing zno nanoparticles at different concentrations (e.g. 1%, 3%, 5%  and 3%  nano-zno pulse 10% polyethylene grafted maleic anhydride (pe-g-ma), w/w pure ldpe), were p...

A protein packaging film was successfully prepared using whey protein concentrate (WPC) as raw material. Protein concentration, plasticizers concentration and temperature were discussed. Research results show that the increasing of protein concentration lead to decreasing barrier properties of WPC film but improving its mechanical properties. Though barrier properties of WPC film lost to some e...

BARRIER PROPERTIES OF MUCUS Hasan M. Yildiz, Chemical Engineering, Northeastern University Mucus, a complex network consisting of microand nano-scale fluid-filled domains formed via mucin glycoprotein interactions, provides a barrier through which nutrients and orally delivered drugs must penetrate before entering the circulatory system. Mucus provides a significant, yet poorly characterized ba...

The airway epithelium forms a physical, chemical and immunological barrier against inhaled environmental substances. In asthma, these barrier properties are thought to be abnormal. In this study, we analysed the effect of grass pollen on the physical and immunological barrier properties of differentiated human primary bronchial epithelial cells. Following exposure to Timothy grass (Phleum prate...

In this paper we analyse financial implications of exchangeability and similar properties of finite dimensional random vectors. We show how these properties are reflected in prices of some basket options in view of the well-known put-call symmetry property and the duality principle in option pricing. A particular attention is devoted to the case of asset prices driven by Lévy processes. Based o...

To apply the nanomaterial as a component in the packaging material structure, in this research, the carboxymethyl cellulose (CMC)/polyvinyl alcohol (PVA) film were prepared with three levels of nanoclay particles (0.5, 1 and 3%) using solution casting evaporation method. The incorporation of nanoclay on mechanical, water vapor permeability, and oxygen barrier properties of CMC/PVA-based film wa...
