Carbon dots co-doped with nitrogen and sulfur (NSCDs) were obtained from thiourea and TAE (Tris-acetate-ethylenediamine) buffer using microwave assisted hydrothermal synthesis. The synergistic presence of nitrogen and sulfur as a dopant results in teasing fluorescence properties and a fluorescence quantum yield of 57%. An HR-TEM study showed the NSCDs to be mono-dispersed and seemingly spherical with an average hydrodynamic diameter of 3.6 ± 0.88 nm. The NSCDs are nontoxic as proven by an MTT assay for cytotoxicity. The optical characterization was done by using UV-Vis absorption and fluorescence spectroscopy which revealed excitation wavelength-dependent multicolor emissions. The characterization of surface topology was done by using X-ray diffraction, FTIR, and X-ray photoelectron spectroscopy. The NSCDs were used to image various pathogenic bacteria (E. coli, Klebsiella, Pseudomonas & Staphylococcus) and human buccal epithelial cells by applying multicolor fluorometry. Graphical abstract Schematic presentation of microwave-assisted hydrothermal synthesis of nitrogen and sulfur doped carbon dots (NSCD) based on Thiourea and 50X Tris-acetate-ethylenediamine (TAE) buffer having multicolor fluorescence, used for tagging and imaging pathogenic bacteria and Human buccal epithelial cells using fluorescence microscope.

G., “Co-Cu alloy nanoparticles decorated TiO2 nanotube arrays for highly sensitive and selective nonenzymatic sensing of glucose”, Sensors and Actuators, B: Chemical, vol. 215, pp. 337-344, 2015.[Abstract]

A nonenzymatic glucose sensor was fabricated by electrodepositing cobalt rich cobalt-copper alloy nanoparticles (Co-CuNPs) on vertically aligned TiO2 nanotube (TDNT) arrays. For this, TDNT arrays with tube diameter of 60 nm were synthesized by electrochemical anodization. The composition of the electrodeposited alloy was optimized based on the electrocatalytic activity towards glucose oxidation. This is achieved by controlling the concentration of electrolyte and time of deposition. Chemical composition of the optimized Co-Cu alloy nanoparticles is determined to be Cu0.15Co2.84O4 with fcc crystalline structure. The sensor showed two linear range of detection with high sensitivity of 4651.0 μA mM-1 cm-2 up to 5 mM and 2581.70 μA mM-1 cm-2 from 5 mM to 12 mM with a lower detection limit of 0.6 μM (S/N = 3). The sensor is highly selective to glucose in the presence of various exogeneous and endogeneous interfering species and other sugars. The response of the sensor towards blood serum was in good agreement with that of commercially available glucose sensors. © 2015 Elsevier B.V.

Ramachandran, “Electrodeposition of aluminium and aluminium-copper alloys from a room temperature ionic liquid electrolyte containing aluminium chloride and triethylamine hydrochloride”, International Journal of Minerals, Metallurgy and Materials, vol. 20, no. 9, pp. 909-916, 2013.[Abstract]

The electrodeposition of Al and Al-Cu binary alloys on to gold substrates from a room temperature ionic liquid electrolyte containing AlCl3-Et3NHCl was studied. The electrochemical behavior of the electrolyte and the mechanism of deposition were investigated through cyclic voltammetry (CV), and the properties of deposits obtained were assessed by scanning electron microscopy with energy dispersive X-ray spectroscopy (SEM-EDS) and X-ray diffraction (XRD). Al of 70 μm in thickness and an Al-Cu alloy of 30 μm in thickness with 8at% copper were deposited from the electrolyte. SEM images of the deposits indicate that the Al deposit was smooth and uniform, whereas the Al-Cu deposit was nodular. The average crystalline size, as determined by XRD patterns, was found to be (30 ± 5) and (29 ± 5) nm, respectively, for Al and Al-Cu alloys. Potentiodynamic polarization (Tafel plots) and electrochemical impedance spectroscopic (EIS) measurements showed that Al-Cu alloys are more corrosion resistant than Al. More »»

Abstract Tantalum oxide honeycomb nanostructures (THNS) were fabricated by electrochemical anodisation of tantalum in H2SO4–HF medium. \{XRD\} analysis showed that annealing of \{THNS\} at 400 °C improves the crystallinity. \{HRSEM\} and \{AFM\} results illustrated that nanopores with an average diameter of 30 nm were uniformly distributed and the pore size reduced to 24 nm and 18 nm during subsequent electrodeposition of Pt and CuO. Electrodeposited Pt and CuO exhibited face centered cubic (fcc) and monoclinic crystal structure respectively. Cyclic voltammetric studies revealed that, on the hybrid material electrooxidation of glucose occurs at a lower potential (0.45 V). The sensor exhibited linear response to glucose up to 31 mM, fast response time (<3 s) and a low detection limit of 1 μM (S/N=3). The sensor is free of interference from ascorbic acid, uric acid, dopamine and acetaminophen. Sensor was used to analyze glucose in blood serum samples.

Development and use of highly ordered, vertically aligned TiO2 nanotube arrays modified with gold nanoparticles for the selective detection of ascorbic acid (AA) in the presence of uric acid and glucose are reported here. Gold nanoparticles were electrodeposited on the Nanotube arrays by CV. The sensor was characterized using SEM, EDS, CV, and EIS. It showed very good performance with a sensitivity of 46.8 μA mM−1 cm−2, response time below 2 seconds and linearity in the range of 1 μM to 5 mM with a detection limit of 0.1 μM and was tested for the AA concentration in pharmaceutical preparations.
