Abstract Gum acacia and sodium alginate were blended to synthesize highly efficient superadsorbent formed by grafting of poly(acrylic acid) (AA) used as monomer onto the hybrid of gum acacia and sodium alginate and the polymeric chains were crosslinked through N,N′-methylene bisacrylamide (MBA). The overall reaction followed free radical polymerization with ammonium persulphate (APS) used as initiator. Response surface methodology integrated with central composite design (RSM-CCD) could synthesi...

Abstract The present research work reveals semi-interpenetrating network (semi-IPN) synthesis using response surface methodology-central composite design (RSM-CCD) based optimization. The maximum swelling of 362.11% was obtained with monomer, crosslinker and initiator concentrations 4.39 mol L−1, 1.52 mol L−1 and 4.58 mol L−1, respectively, temperature 70 °C, time 3 h and pH 4.0. The synthesized hydrogel showed 94.16% and 95.62% removal for eosin yellow (EY) and eriochrome black-T (EBT) dyes, re...

This paper describes the fabrication of silver nanocomposites based on semi interpenetrating network (semi-IPN) and interpenetrating network (IPN) matrices and their antibacterial activity. The semi-IPN and IPN matrices were prepared under microwave radiation using polyacrylic acid and polyacrylamide chains to graft copolymerize the polysaccharide fraction of gum Salai guggal. After optimizing the reaction parameters with respect to maximum water absorption capacity, the synthesized semi-IPN and...

Abstract In the present work synthesis of novel silver nanocomposite Sg-cl-polyAAm-IA-Ag0 based on gum Salai guggal semi interpenetrating network (semi-IPN) Sg-cl-polyAAm-IA and its antimicrobial behavior has been described. Semi interpenetrating network was prepared under hot air conditions using acrylamide and N,N′-methylenebisacrylamide under the initiation impact of ammonium persulphate. Different process variables were optimized and maximum swelling percentage obtained was 667 ± 11%. The si...

: Kidney transplantation is usually the best course of treatment for patients with end-stage renal disease. En bloc kidney transplantation (EBKT) is a surgical treatment option that increases available donor organs with excellent graft survival for patients with end-stage renal disease. Herein, we report a case of an unusual bilateral renal parenchymal urine leak after EBKT leading to removal of both moieties of the EBKT. This unfortunate complication after EBKT, to our knowledge, is the only re...

In this work, phase transition and dielectric behavior of nematic liquid crystal (NLC), E7 and zinc oxide (ZnO) nanoparticles (NPs) doped nematic liquid crystals are investigated. Effect of nano-particles dispersion is analyzed and compared with the dielectric behavior of E7 and E7-ZnO. Frequency dependent dielectric permittivity at various temperatures in nematic phase for E7 and E7-ZnO sample is also studied.In this work, phase transition and dielectric behavior of nematic liquid crystal (NLC)...

Abstract Orange azo dichroic dye dependent droplet configuration and electro-optic (EO) characteristics of polymer dispersed liquid crystals (PDLCs) were studied. PDLCs were prepared using a nematic liquid crystal (LC) and UV-curable liquid photopolymer in equal ratio by polymerization induced phase separation (PIPS) technique. Orange azo dichroic dye was taken in different concentrations (wt./wt. ratio) particularly 0.0625, 0.125, 0.25, 0.5 and 1% of the LC mixture to prepare different PDLC sam...

Main objective of present work is to study the efficiency of mixed fuel towards solution combustion synthesis of alumina powder, which otherwise prepared by single fuel and study of properties of final product with mixed fuel approach. Two different fuels, glycine and urea, along with aluminium nitrates have been used to prepare nanophase alumina powder. Different fuel to oxidizer ratios and different percentage combination of two fuels were used to prepare six samples. In all samples, nanoscale...

This paper presents an approach for study of gene expressions based on Markov chain theory. A mathematical model has been proposed to study the transcription of DNA into mRNA and translation of mRNA into Proteins. It is assumed that the DNA, mRNA and Proteins are states in the model and initial state of the system is known. Based on the initial state, the successive states (without state feedback) are predicted using probabilities. The model is used to predict the final state Proteins of the sys...
