In this research thin film heterogeneous cation exchange membrane was prepared by interfacial polymerization of polyacrylic acid-co-iron nickel oxide nanoparticle son PVC based substrate. Spectra analysis confirmed graft polymerization conclusively. The SEM images showed that polymerized layer covers the membranes by simple gel network entanglement. Results exhibited that membrane water content...

Holdup was measured at various frequencies, amplitudes, continuous and dispersed phase flow rates for binary systems in a pulsed plate column capable of providing samples at various heights. The binary systems was so selected as to cover a wide spectrum of interfacial tensions. Dispersed phase holdup was found to increase with height in a logarithmic fashion at conditions away from the flooding...

Computer-mediated environments have become a core feature of work and learning environments. The screenface furthers the understanding of the ways in which individuals interact with others and indeed with the artefact, the computer. While interface design standardises the kinds of interaction available, individuals negotiate their interaction with the computer in highly individualistic ways. Th...

Microorganisms synthesise a wide range of surface-active compounds (SAC), generally called biosurfactants. These compounds are mainly classified according to their molecular weight, physico-chemical properties and mode of action. The low-molecular-weight SACs or biosurfactants reduce the surface tension at the air/water interfaces and the interfacial tension at oil/water interfaces, whereas the...

Oxide/water interfaces are ubiquitous in a wide variety of applications and the environment. Despite this ubiquity, and attendant decades of study, gaining molecular level insight into water/oxide interaction has proven challenging. In part, this challenge springs from a lack of tools to concurrently characterize changes in surface structure (i.e., water/oxide interaction from the perspective o...

Introducing chemical interaction between functional groups/polar sites on the host with PS is emerging as a more effective approach for caging sulfur species.[5] Recent reports found that using functionalized carbon[6,7] and m...

Microemulsions are dispersions of water and oil stabilized by one or mixtures of surfactants. The key differentiators from other dispersions are: (i) domain size of the dispersed phase is of the order of 5-100 nm in size (Schulmann et al., 1959); (ii) thermodynamically stable (Zana, 1994), and (iii) optically isotropic (Danielsson and Lindman, 1981). Commonly observed structures are: oil in wat...

Synthetic antiferromagnet (SAF) nanostructures with an interfacial Dzyaloshinskii–Moriya interaction can host topologically distinct spin textures, such as skyrmions, and therefore, are regarded promising candidates for both spintronics magnonics applications. Here, we present comprehensive micromagnetic simulations of material systems discuss the rich phase diagrams that contain various types ...
