Electrochemistry and Nanomaterials Laboratory

Dr. Rangarajan's research group’s primary interest is in the use of electrochemistry for synthesis and modification of functional and nanomaterials, and their use in a variety applications including catalysis, sensors, drug delivery, and integrated circuit packaging. They design materials and processes by seeking fundamental understanding of structure-property relations, and how material structure is influenced by multiple processes that occur during materials synthesis. They use both experiments and simulations for this purpose.

  1. Electrodeposition in the Nano- and Micro-Sca
    One of the main pursuits in their lab is the design of nano- and micro-structures of materials through electrodeposition. They study how parameters such as electrolyte composition (including pH), additives, current density/potential of deposition (including pulsing), and enhanced mass transfer may be optimized to design specific structures for enhanced properties.

    Lead-free Alloys for Integrated Circuit Packaging
    They are studying Bi, SnBi, and SnIn alloys as lead-free alternatives for integrated circuit packaging. The primary challenge is in uniform co-deposition of Sn and Bi, which are separated by ~ 450 mV, or Sn and In, which are separated by ~ 490 mV. Using acidic baths, the team have been able to co-deposit Sn and Bi, and form deposit SnBi alloys from 5% to 75% Sn, including the eutectic (42% Sn) through judicious design of the deposition process. They have also demonstrated that these alloys can be deposited in templated patterns, as a prelude to their use in flip-chip joining.

    Collaborators: Dr. Madhav Datta, Distinguished Professor and Director, Amrita Center for Industrial Research and Innovation.

    Electro-reduction of Graphene Oxide
    They are studying electro-reduction of graphene oxide synthesized through different modifications of Hummers method. Graphene oxide has been reduced through both constant potential reduction as well as cyclic voltammetry. This reduced graphene oxide (eRGO) is used for catalytic and sensing applications

    Electrodeposition of Metal and Metal Oxide Nano- and Micro-structures
    Electrodeposition of bismuth from acidic nitrate baths is being pursued. The research group have obtained branched nano-scale hexagons (100 nm to 1 mm) and larger micron-sized hexagons (up to 20 mm) by inducing a competing reaction (nitrate reduction). Branched nano-hexagons have been able to detect ultratrace quantities of lead. Further studies are ongoing to design nanostructures (oval/triangular disks, rods, flowers, polyhedrons, spindles) of bismuth.
    In some preliminary studies, they have also electrodeposited silver nanoparticles and iron oxide nanoparticles for sensing and catalytic applications. Of particular interest is the use of electrodeposited bismuth for detection of low magnetic fields.

    Positions Open: Master’s project opportunities (6 months to 1 year) are available for designing metal/metal oxide nanostructures through electrodeposition.

  2. Electrochemical Sensors
    One of the main focus of the research groups is the development of low-cost, portable electrochemical sensors. Electrochemical sensors can be designed with high sensitivity and selectivity, are capable of detecting analytes at low concentrations, and are amenable to lab-on-a-chip design for simultaneous detection of multiple analytes. In addition to developing novel materials as sensing platforms, their work also focuses on designing sensing protocols that enhance sensor performance. Voltammetric techniques, which pulse/scan the applied potential on the sensing platform and measure differential currents, are our focus.

    They have developed an electrodeposited bismuth-based sensor for ultratrace detection of lead (LoD: 0.05 ppb, Range: 0.1 to 10 ppb, Sensitivity: ~ 0.75 mA/ppb). They have also developed graphene-based electrochemical sensors for pharmaceutical compounds – salicylic acid (LoD: 10 mM, Range: 25 to 2250 mM,Sensitivity: 0.396 mA/mM-cm2), paracetamol (LoQ: 1 nM, Range: 1 nM to 1 mM,Sensitivity: 1.43 mA/mM-cm2), and phenytoin (LoQ: 1 nM, Ranges: 1 to 750 nM and 0.75 to 100 mM, Sensitivity: 30.19 mA/mM-cm2, 121.35 mA/mM-cm2). Another area of focus is the development of graphene-based electrochemical sensors for micronutrients in food samples – ascorbic acid in lime juice and amla extracts (LoD: 0.01 mM, Range: 1 to 5000 mM, Sensitivity: 0.178 mA/mM-cm2).

    Dr. N. Madhu Mohan, Department of Electronics and Communication Engineering (Portable potentiostats)

  3. Nanoparticles for Drug Delivery

    In addition to electrodeposition of iron oxide nanoparticles, the research group have also developed a simple solution-phase protocol for synthesizing these nanoparticles with tunable particle size and superparamagnetic or ferrimagnetic properties. They are currently studying the colloidal stability and the flow behavior of these nanoparticle suspensions in the presence of magnetic fields.

    Dr. Takuya Tsuzuki, Australian National University

  4. Molecular Simulations
    The research group's efforts in simulations are directed towards understanding graphene, how its structure changes due to defects and functional groups arising from partial oxidation, and its interactions with metal particles and analytes. They use advanced semi-empirical methods for simulating graphene.

This work reports a graphene-based nonenzymatic electrochemical sensing platform for the detection of dopamine (DA), uric acid (UA), and ascorbic acid (AA). Graphene oxide, synthesized by modified Hummers method, was thermally reduced in an induction furnace at 200 °C in an Ar-H2 atmosphere to obtain thermally reduced graphene oxide (tRGO). Nanocomposites of tRGO-TiO2 were obtained by a hydrothermal method, and were characterized using Fourier transform infrared (FTIR) spectroscopy, scanning electron microscopy (SEM), high-resolution transmission electron microscopy (HRTEM), and X-ray diffraction (XRD). FTIR spectra showed Ti-O-C peaks, indicating covalent linkage between the TiO2 nanoparticles and the reduced graphene oxide sheets. Glassy carbon electrode (GCE) was modified with the nanocomposite (tRGO-TiO2-GCE), and the modified electrode could detect dopamine (DA: 1 to 1000 μM), uric acid (UA: 1 to 900 μM), and ascorbic acid (AA: 10 to 1000 μM) in each other's presence over wide ranges, with adequate separation in peak potentials. Differential pulse voltammetry experiments yielded linear responses with sensitivities of 133.18, 33.96, and 155.59 μA mM-1 cm-2 for DA, UA, and AA, respectively.

<p>The electrical conductivity and yield of polyaniline (PANi) were optimized using a design of experiments (DOE). PANi samples were synthesized by the chemical oxidative polymerization of aniline using methane sulfonic acid as the dopant acid and ammonium persulfate as the oxidant. The main factors in the synthesis of PANi that can affect the conductivity were identified as (i) the concentration of dopant acid, (ii) oxidant-to-monomer ratio, and (iii) the addition rate of oxidant to monomer. Using a Box-Behnken DOE method the regression equation, main effects plots, contour plots, and optimization plots for conductivity and yield were generated and analyzed. Under the optimized conditions of dopant acid concentration of 0.9M, an oxidant addition rate of 30 mL/h and an OM ratio of 0.9, PANi with a conductivity of 1.95 S/cm and yield of 95% was obtained. The observed trends in the four-point probe conductivity measurements were correlated with the polymer structure using fourier transform infrared spectroscopy, X-ray diffraction studies, and scanning electron microscopy. © 2013 Wiley Periodicals, Inc.</p>

Different signal processing transforms provide us with unique decomposition capabilities. Instead of using specific transformation for every type of signal, we propose in this paper a novel way of signal processing using a group of transformations within the limits of Group theory. For different types of signal different transformation combinations can be chosen. It is found that it is possible to process a signal at multiresolution and extend it to perform edge detection, denoising, face recognition, etc by filtering the local features. For a finite signal there should be a natural existence of basis in it’s vector space. Without any approximation using Group theory it is seen that one can get close to this finite basis from different viewpoints. Dihedral groups have been demonstrated for this purpose.

<In the present study, the main objective is to evolve a correlation to predict liquid-liquid two-phase heat transfer coefficients in a spiral plate heat exchanger. Experimental studies were conducted in a spiral plate heat exchanger using the liquid-liquid two-phase system of water-diesel in different volume fractions and flow rates as the cold fluid. Experiments were conducted by varying the volumetric flow rate and temperature, keeping the volumetric flow rate of hot fluid constant. The two-phase heat transfer coefficients were correlated with Reynolds number, Prandtl number and volume fraction in the form Nu = a (Re) b (Pr) c (φ) d. The data obtained from fresh experiments were compared with the predictions of the obtained correlation. The predicted coefficients showed a spread of ± 12 % in the laminar range, indicating the potential use for practical applications

This paper presents the results of two-phase (immiscible liquids) heat transfer studies, conducted using a spiral plate heat exchanger. Experimental studies were conducted using hot water as the service fluid. The two-phase system of nitrobenzene-water in different mass fractions and flow rates was studied as a cold process fluid. The two phase heat transfer coefficients were correlated with Reynolds numbers, Prandtl number, and by the following equation Nu = a. (Re)b. (Pr)c. (X)d, adopting an approach available in the literature for the two-phase flows. The data obtained from the experimental study are compared with the theoretical predictions. The predicted coefficients showed a spread of ± 15 % in the laminar range. This new correlation for predicting Nusselt number may be used for practical applications. © 2010 Bulgarian Academy of Sciences, Union of Chemists in Bulgaria. More »»
