Author:Ogunniran, ES; Sadiku, R; Ray, SS; Luruli, NDate:Dec 2011Boehmite alumina nanoparticles are added to PP-g-MAH-compatibilized blends of PA 12 and PP to study the effects of nanoparticle loading in the resulting composites. WAXD and SEM data suggest that the nanoparticles enhanced the coalescence of ...Read more
Author:Adegbola, TA; Rotimi, SE; Suprakas, Sinha RDate:Apr 2016The compounding of rPAN/PET [polyacrylonitrile/poly(ethylene terephthalate]; 30/70, 50/50, and 70/30 wt %) using a melt-blending technique was the main focus of this investigation. An X-ray diffraction study indicated the possibility of ...Read more
Author:Wokadala, OC; Ray, SS; Bandyopadhyay, J; Wesley-Smith, J; Emmambux, NMDate:Aug 2015Polylactide/butylated-starch/nanoclay (70/25.5/4.5 wt%) composites were prepared by melt blending with nanoclays of varying hydrophobicity. Electron microscopy studies indicated that the interphase boundary interaction was highest in the clay ...Read more
Author:Jacobs, V; Patnaik, A; Anandjiwala, RD; Maaza, MDate:Jun 2011Electrospinning of chitosan, a naturally occurring polysaccharide biopolymer, has been investigated. In this paper, the authors report the optimization of electrospinning process and solution parameters using factorial design approach to ...Read more
Author:Mwakikunga, Bonex W; Forbes, A; Sideras-Haddad, E; Arendse, CDate:Oct 2008Laser pyrolysis has been used to synthesize WO3 nanostructures. Spherical nano-particles were obtained when acetylene was used to carry the precursor droplet, whereas thin films were obtained at high flow-rates of oxygen carrier gas. In both ...Read more
Author:Marais, Laurette; Pretorius, LDate:Jul 2023While Grammatical Framework (GF) resource grammars are primarily intended as linguistic software libraries, they can also be employed to enable syntax parsing via the GF runtime system. The isiZulu resource grammar (ZRG) in conjunction with ...Read more
Author:Rebelo, AGDate:1987This preliminary synthesis was designed to promote an understanding of pollination as a process in the Cape flora by summarizing the literature, outlining patterns and processes, and identifying gaps in knowledge. Various aspects of pollination ...Read more

Author:Salehiyan, Reza; Ray, Suprakas SDate:Oct 2018This chapter discusses the structure-properties of immiscible polymer blends, focusing on the effects of compatibilization. It has been discussed that the morphology of immiscible blends governs their final properties and thus end-use ...Read more
Author:Reddy, KO; Maheswari, CU; Reddy, DJP; Guduri, BR; Rajulu, AVDate:Apr 2010The native (untreated) and alkali treated fibers from the ficus leaves were analyzed by Fourier transform infrared (FTIR), Chemical, X-ray and Thermo gravimetric methods. The morphology of the fibers before and after alkali treatment was ...Read more
Author:Jayaramudu, J; Reddy, DJP; Guduri, BR; Rajulu, AVDate:Jun 2009The ligno-cellulose natural fabric from the Polyalthia cerasoides tree was analyzed by FTIR, chemical, X-ray and thermo gravimetric methods. The morphology of the fibers was studied by scanning electron and polarized optical microscopic ...Read more
Author:Van Huyssteen, GBDate:2010Overall, this article aims to (re)define the component structures in Afrikaans morphological constructions from a cognitive grammar perspective. The author will not pay attention to general issues in cognitive grammar, such as the status of ...Read more
Author:Jayaramudu, J; Agwuncha, SC; Ray, SS; Sadik, ER; Varada Rajulu, AVDate:2015In the present work, natural Polyalthiacerasoide woven fabrics were extracted from the bark of the tree and using these woven fabrics/glass fibre as reinforcements and epoxy as matrix the hybrid composites were prepared by the hand lay-up ...Read more
Author:Malwela, T; Ray, SSDate:Apr 2012Thin films of unmodified and nanoclay-modified polylactide/poly(butylene succinate) (PLA/PBS) blends were prepared on a glass substrate with a spin coater. The morphology and crystal growth behaviours for the films, crystallized at different ...Read more
Author:Malwela, T; Ray, SSDate:Feb 2011This communication reports a unique morphology of dispersed clay particles in a polymer nanocomposite. A nanocomposite of poly[butylene succinate)-co-adipate] (PBSA) with 3 wt% of organically modified montmorillonite was prepared by melt-blending ...Read more
