Metal-organic frameworks (MOFs) are emerging material class for the past few years due to its tailorability characteristics for various applications. However, the research and development (R&D) of MOFs is still scarce for fuel cell system. This may be due to the several difficulties faced in selecting a good MOFs-based electrolyte, which consequently affects both proton conduction and methanol ...

Although the fundamental concepts of pharmacokinetics remain the same, ocular pharmacokinetics has its own challenges due to the uniqueness of barrier properties posed by various ocular tissues and its growing complexity with different routes of ocular administration. A thorough understanding of the barrier nature will aid in tailoring a drug or its carrier's physicochemical properties to its a...

Ursodeoxycholic acid and its main conjugate glycoursodeoxycholic acid are bile acids with neuroprotective properties. Our previous studies demonstrated their anti-apoptotic, anti-inflammatory, and antioxidant properties in neural cells exposed to elevated levels of unconjugated bilirubin (UCB) as in severe jaundice. In a simplified model of the blood-brain barrier, formed by confluent monolayer...

the starch based films have some disadvantages such as weak mechanical and poor water barrier properties that restrict their applications in food packaging. in the present research, the polyvinyl alcohol (povh), as a compatible polymer, and montmorillonite (mmt) nanoclay, as a nanofiller, were added to plasticized starch film (ps) to improve its properties and also to produce ps-mmt-pvoh nanoco...

This paper presents finite element analysis (FEA) of a coated and uncoated cylinder heads of a diesel engine to examine the distribution of temperature and stress. A thermal barrier coating system was applied on the combustion chamber of the cylinder heads, consists of two-layer systems: a ceramic top coat (TC), made of yttria stabilized zirconia (YSZ), ZrO2-8%Y2O3 and also a metallic bond coat...

In matching theory, barrier sets (also known as Tutte sets) have been studied extensively due to its connection to maximum matchings in a graph. In this paper, we first define θ-barrier sets. Our definition of a θ-barrier set is slightly different from that of a barrier set. However we show that θ-barrier sets and barrier sets have similar properties. In particular, we prove a generalized Berge...

background: psychological and behavioral domains are important in coping with type ii diabetes. this study was conducted to assess supportive and coping obstacles in living with type ii diabetes among patients who visited hospitals affiliated to tehran university of medical sciences (tums). methods: this was a cross-sectional study with 600 subjects who participated in the study. data collectio...

The interplay between turbulent bursts and transport barriers in analyzed with a simplified model of interchange turbulence in the Scrape-Off Layer of magnetically confined plasmas. The turbulent bursts spread into the transport barriers, and, depending on the competing magnitude of the burst and stopping capability of the barrier can burn through. Two models of transport barriers are presented...
