    Studies on natural rubber containing kaolin modified with hexamethylenediamine derivative of phosphorylated cashew nut shell liquid prepolymer

    Sreelekshmi R.V., Brahmakumar M., Sudha J. D., Ravindranatha Menon A. R.*
    Kaolin was modified with a solution of phosphorylated cashew nut shell liquid prepolymer (PCNSL) containing hexamethylenediamine (HMDA). The organomodified kaolin was characterized using X-ray diffraction (XRD), scanning electron microscopy (SEM), thermogravimetric analysis (TGA) and infrared spectroscopy (FTIR). Processability characteristics and physico-mechanical properties of natural [...]

    Ionic Liquids / Ionic Liquid Crystals for Safe and Sustainable Energy Storage Systems

    Sudha J. Devaki and Renjith Sasi
    Ionic liquid crystals are organic salts having synergistic properties of ionic liquids and
    liquid crystalline materials endowed with non-covalently bound delocalised ion pairs
    of large organic cations and anions. They can undergo stimulus-responsive anisotropic
    phase change, followed by enhancement in ionic diffusion and conductivity, which
    makes them ideal candidates as electrolyte in energy storage [...]

    Design of Macroscopically Ordered Liquid Crystalline Hydrogel Columns Knitted with Nanosilver for Topical Applications

    Reshma Lali Raveendran, Nishanth Kumar Sasidharan, and Sudha J. Devaki*
    The design of liquid crystalline hydrogels knitted with silver nanoparticles
    in macroscopic ordering is becoming a subject of research interest due to their promising
    multifunctional applications in biomedical and optoelectronic applications. The present
    work describes the development of liquid crystalline Schiff-based hydrogel decorated
    with silver nanoparticles and the demonstration of [...]

    Self–assembly of Anacardic Acid Derived Cation– modified Montmorillonite into ’Arthropodal’ Branched Nanofibers

    Asha Susan Chacko and Vadakkethonippurathu Sivankuttynair Prasad*
    Montmorillonite (MMT) was organo-modified with tri-(2- carboxy-3-pentadeca-8,11,14]-trienylphenoxy) aminopropylsilyl sulfate cation, synthesized from anacardic acid (AA), a biomonomer by cation exchange and characterized. The modified product (AAM) showed a decreased crystallinity with an increase in d-spacing of MMT from 1.47 nm to 2.29 nm attributed to intercalation by modification. AAM [...]

    Semi-interpenetrating network composites of poly (lactic acid) with cis-9-octadecenylamine modified cellulose-nanofibers from Areca catechu husk

    Sumesh Soman, Asha Susan Chacko, Vadakkethonippurathu Sivankuttynair Prasad
    Poly(lactic acid)/cellulose-nano fiber (PLA/CNF) composites were prepared with CNF synthesized from the areca husk fibers (AHF) by TEMPO-mediated oxidation for the first time and the properties were evaluated. MCNF synthesized by the controlled amidation of CNF with cis-9-octadecenylamine (OA) resulted in PLA/MCNF composites with higher mechanical properties and [...]

    Dietary fibre and phenolic-rich extracts from Musa paradisiacal inflorescence ameliorates type 2 diabetes and associated cardiovascular risks

    K.B. Arun , Sithara Thomas, T.R. Reshmitha , G.C. Akhil , P. Nisha*(2017)
    The present study investigated nutraceutical properties of Musa paradisiaca (Nendran variety) inflorescence (PI). PI was found to be a rich source of soluble (SDF) and insoluble dietary fibre (12.45 and 53.31% respectively). SDF exhibited potential glucose and cholesterol adsorption capacity. Ethyl acetate [...]

    DNA and mitochondrial protective effect of lycopene rich tomato (Solanumlycopersicum L.) peel extract prepared by enzyme assisted extraction against H2O2 induced oxidative damage in L6 myoblasts

    T.R. Reshmitha, Sithara Thomas, S. Geethanjali, K.B. Arun, P. Nisha * (2017)
    Lycopene rich extracts (ETE) were prepared by enzyme assisted extraction of tomato peel. Oxidative damage was induced in L6 myoblasts by exposing cells to H2O2 in presence and absence (control) of ETE. The potential of ETE to protect cells from oxidative damage was [...]
