Barrier property of materials to microbes is an important aspect in many applications like wound dressingsand skin substitutes. Lack of a standard method for the evaluation of microbial barrier property limits the considerationof this important aspect by many bioengineers and biomaterial scientists. Thus, in this study we areintended to develop a standard method for the quantitative assessment of Microbial Barrier Property (MBP) andexpress this in terms of percentage in comparison with a control which resembles a bare wound or a standard existingwound coverage material. In this study, we have evaluated the microbial barrier property of electrospun materialswith different pore spaces and our study showed that this method can be successfully used for the assessment of bacterialbarrier property of materials intended for wound dressing and skin substitute applications. Further, the resultsshowed that the MBP will vary with the test conditions. This methodology can be used to measure the microbialbarrier property of wide range of materials like skin substitute materials, wound dressings, medical textiles and manyother materials where microbial prevention is important. This methodology can also be extended to the specificdetermination of bacterial, fungal or viral barrier property with minor modifications.

First quantitative dung beetle-feeding trophic network analysis for the Oriental region is carried out by inves tigating trophic network interaction between dung beetles and mammal dung types in the moist forests of the Western Ghats a global biodiversity hot spot in south-western India. Dung-beetle assemblage associated with the dung of the prominent mammals, such as the macaque, boar, gaur, elephant and deer, showed differences in richness, abundance and composition among different dung types. Most dung beetles were generalists with low resource specificity and community-wide generalist feeding on herbivore and omnivore dung types. Dung beetles in the region displayed high species richness and abundance in boar dung. The high attraction and specificity of dung beetles towards the odoriferous boar dung indicate that the omnivore mammal Sus scrofa has a major role in maintaining the dung beetle community in the forests of the Western Ghats. Network interaction analysis shows that the vast majority in the assemblage are generalist species, and the few specialist species were all with low abundance. Low overall specialisation and low resource partitioning with high species richness is recorded in the assemblage. The assemblage’s trophic level preference is reflected in the high dung specificity recorded in the omnivore and herbivore dung types.

Liquid crystal (LC) has long been a feature in Materials Science and Nanotechnology, have recently been extended into theappealing domain of complex hybrid materials. The crystalline structural eff ects of alkoxy chain lengths and the mesogenproperties of hydrogen-bonded (n-OBASA) complexes (n = 5,6,7) have been investigated in recent studies. The LC-basedhybrid nanocomposite materials–obtained by the homogeneous dispersion of zinc oxide nanowires (ZnO NWs) as a dopantinto hydrogen-bonded liquid-crystalline compounds—seem to be particularly promising in this article. Optimizing thegeometry of surface stabilizing electro-optic, LC cell reveals the typical intermolecular hydrogen bond (H-bond) formation. Here, we explore molecular-colloidal hybrid composite matrix formed from LCs and dilute dispersions of orientation-orderedZnO NWs, for eventual potential application in smart switchable display devices. In addition, we investigated the structural,dielectric and optical properties of the nanocomposite, and electro-optical studies which were performed by exploiting thepotential during the conditions before the opening of spectrum acquisition. Our novel fi ndings confi rm that the electric fi eldinduces a charge transfer of the LC molecules to the nanomaterial, which acts as a trap for ionic charges. This eff ect maybe utilized to achieve superior switching operation that is electro-optically tunable. Such dynamic novel switching could beharnessed in smart LCD technology and pave the way towards innovative display modulation techniques.
