Novel hydrodynamic cavitation based hand pump for disinfection of groundwater

Sarjerao Bapu Doltade, Aniruddha Bhalchandra Pandit

Environmental Quality Management > 32 > 1 > 473 - 482

India Mark‐II hand pump was successfully modified in the present study so as it can serve as an efficient tool for the disinfection of the borewell water. This modified Hand Pump works on the principle of hydrodynamic cavitation, which can potentially disrupt the bacteria and fungi rendering them unviable. The reduction in organic carbon was also found in the borewell water. However hydrodynamic cavitation...

Analytical and numerical investigations of mixing fluids in microchannel systems of different geometrical configurations

Vikram V. Shanbhag, Joydeb Mukherjee, Aniruddha Bhalchandra Pandit

The Canadian Journal of Chemical Engineering > 100 > 9 > 2217 - 2229

This work presents theoretical and numerical studies related to micromixing phenomena using two different shapes of microchannel systems (i.e., X‐ and Y‐shaped, respectively). In this study, we consider a system that consists of a primary fluid, an aqueous phase (Fluid A), and a secondary fluid (distributed phase), Rhodamine B, in water (Fluid B). In this study, a two‐dimensional closed‐form generalized...

Closed form solutions of convection‐diffusion mechanisms in two dimensions for H₂ separation from (H₂/CO₂) mixture at room temperature

Joydeb Mukherjee, Ankita Bose, Aniruddha Bhalchandra Pandit, Nandini Das

The Canadian Journal of Chemical Engineering > 99 > S1 > S863 - S880

Studies pertinent to the hydrogen based clean energy systems have seen a significant surge in this decade in order to meet the ever‐increasing demand for energy in an environmentally sustainable way. In order to harness hydrogen from available sources, development and characterization of zeolite membranes with high hydrogen selectivity is of pivotal importance. In this study, a sonication based hydrothermal...

Ultrasonic hyperactivation of cellulase immobilized on magnetic nanoparticles

Mayur Ramrao Ladole, Jayesh Sevantilal Mevada, Aniruddha Bhalchandra Pandit

Bioresource Technology > 2017 > 239 > C > 117-126

In the present work, effect of low power, low frequency ultrasound on cellulase immobilized magnetic nanoparticles (cellulase@MNPs) was studied. To gain maximum activity recovery in cellulase@MNPs various parameters viz. ratio of MNPs:cellulase, concentration of glutaraldehyde and cross-linking time were optimized. The influence of ultrasonic power on cellulase@MNPs was studied. Under ultrasonic conditions...

Synthesis of glycinamides using protease immobilized magnetic nanoparticles

Abha Sahu, Pallavi Sharad Badhe, Ravindra Adivarekar, Mayur Ramrao Ladole, more

Biotechnology Reports > 2016 > 12 > C > 13-25

In the present investigation, Bacillus subtilis was isolated from slaughterhouse waste and screened for the production of protease enzyme. The purified protease was successfully immobilized on magnetic nanoparticles (MNPs) and used for the synthesis of series of glycinamides. The binding and thermal stability of protease on MNPs was confirmed by FTIR spectroscopy and TGA analysis. The surface morphology...

Process intensification of delignification and enzymatic hydrolysis of delignified cellulosic biomass using various process intensification techniques including cavitation

Karuna Narsappa Nagula, Aniruddha Bhalchandra Pandit

Bioresource Technology > 2016 > 213 > C > 162-168

Different methods of pretreatment including alkali treatment, treatment with ultrasound, biological treatment using laccase enzyme and combined treatment like ultrasound-laccase for Napier grass have been tried. With alkali pretreatment optimized conditions obtained were sodium hydroxide 0.3% w/v giving 86% delignification at temperature of 80°C, treatment time of 2h. In physical methods of treatment...

Synthesis of nanosized calcium carbonate using reverse miniemulsion technique: Comparison between sonochemical and conventional method

Amruta Udaykumar Badnore, Aniruddha Bhalchandra Pandit

Chemical Engineering & Processing: Process Intensification > 2015 > 98 > Complete > 13-21

The present work deals with a novel sonochemical synthesis of calcium carbonate (CaCO₃) by reverse miniemulsion technique using ultrasound and compares the results with conventional route of synthesis without the ultrasound. The effect of power density on the obtained particle size, crystallinity, crystallite size and morphology of the prepared CaCO₃ were investigated and optimized. XRD, SEM, TEM,...

Development of Smart Nanocontainers With A Zinc Phosphate Core and A pH-Responsive Shell for Controlled Release of Immidazole

Ananda Jaysing Jadhav, Sammit Ekanath Karekar, Dipak Vitthal Pinjari, Yogesh Gajanan Datar, more

Hybrid Materials > 2015 > 2 > 1

A simple and flexible method has been developed to fabricate reversibly switchable nanocontainers (by layer by layer assembly) using zinc phosphate (ZP) nanoparticles as a core material and subsequent deposition of oppositely charged species of polyelectrolyte (polyaniline and polyacrylic acid) and organic corrosion inhibitor (immidazole). Immidazole was entrapped between polyaniline (PANI) and polyacrylic...

Studying the effect of nature of glass surface on immobilization of glucose isomerase

Viki Rajendra Chopda, Karuna Narsappa Nagula, Dnyaneshwar Vitthal Bhand, Aniruddha Bhalchandra Pandit

Biocatalysis and Agricultural Biotechnology > 2014 > 3 > 3 > 86-89

Immobilization of glucose isomerase (GI) (EC 5.3.1.5) has been carried out on non-porous glass surfaces using γ-aminopropyltriethoxysilane and polyethyleneimine as an activator and gluteraldehyde as cross linking agent for its potential use. Polyethyleneimine was found to be a superior immobilization activator than γ-aminopropyltriethoxysilane. Further, the effects of rough and smooth surfaces of...

Exploration of a Cheaper Carbon Source for Extracellular β-glucosidase Synthesis from Debaryomyces pseudopolymorphus NRRL YB-4229

Ninad Tushar Pandit, Aniruddha Bhalchandra Pandit

Applied Biochemistry and Biotechnology > 2014 > 172 > 7 > 3606-3620

In the present work, interactions between common media components and fermentation conditions were explored to come up with a simple media recipe for extracellular β-glucosidase (Dβ-gl) synthesis from Debaryomyces pseudopolymorphus to substitute cellobiose, which is currently used as a sole carbon source. Taguchi L₂₅ orthogonal array design was used to screen factors influencing Dβ-gl synthesis (carbon,...

Room temperature synthesis of crystalline CeO2 nanopowder: Advantage of sonochemical method over conventional method

Dipak Vitthal Pinjari, Aniruddha Bhalchandra Pandit

Ultrasonics - Sonochemistry > 2011 > 18 > 5 > 1118-1123

In the present study, nano-sized ceria (CeO ₂ ) powders were prepared using conventional and sonochemically assisted precipitation method, without any stabilizers, using cerium nitrate as a starting material and sodium hydroxide as a precipitating agent. The synthesized ceria powders were characterized by XRD, TGA and SEM to determine crystallite size, % crystallinity, thermal weight loss...
