Synthetic resin, Amberlite XAD-4 was linked covalently with the third generation supramolecule, octa-O-methoxy resorcin [4] arene through -N=Ngroup to form chelating resin, which has been characterized and effectively used for the separation and preconcentration of metal ions such as Ni(II), Cu(II), Zn(II) and Cd(II). Critical parameters such as pH, flow rate, sorption capacity, breakthrough st...

This paper surveys emerging design research on co-located group interaction with tabletop displays as an approach toward developing an upperlimb movement rehabilitation system for acquired brain injury (ABI). Traditional approaches and newer virtual reality interventions for physical therapy tend to focus on individuals interacting one-on-one with a therapist in a clinical space – this is both ...

Based on isotope labelling, we found that liquid water can afford an ultrafast permeation through graphene-based nanochannels with a diffusion coefficient 4-5 orders of magnitude greater than in the bulk case. When dissolving ions in sources, the diffusion coefficient of ions through graphene channels lies in the same order of magnitude as water, while the ion diffusion is slightly faster than ...

The potential of various chemically modified rice husk to remove Methylene Blue (MB) and Reactive Orange 16 (RO16) from aqueous solution was investigated. It was found that ethylenediamine tetraacetic acid modified rice husk (ERH) has the highest adsorption capacity for both MB and RO16. ERH was produced by treating natural rice husk (NRH) with 0.5 g of ethylenediamine tetraacetic acid (EDTA) i...

salicylic acid-formaldehyde-m-cresol (sfm) terpolymer had been synthesized in dmf media by conventional method. the resulting resin had been characterized by ftir spectra, elemental and thermogravimetric analyses. the morphology of sfm resin had been studied by sem and optical photograph. various parameters like rate of equilibration, effect of ph on ion exchange capacity and effect of concentr...
