High-energy consumption in our day-to-day life can be balanced not only by harvesting pollution-free renewable energy sources, but also requires proper storage and distribution of energy. In this regard, lithium ion batteries are currently considered as effective energy storage devices and involve the most active research. There exist several review articles dealing with various sections of LIBs, such as the anode, the cathode, electrolytes, electrode-electrolyte interface etc. However, the anode is considered to be a crucial component affecting the performance of LIBs as evident from the tremendous amount of current research work carried out in this area. In the last few years, advancements have been focused more on the fabrication of the nanostructured anode owing to its special properties, such as high surface area, short Li+ ion diffusion path length, high electron transportation rate etc. As the work in this area is growing very fast, the present review paper deliberates the recent developments of anode materials on the nanoscale. Different types of anode materials, such as carbon-based materials, alloys, Si-based materials, transition metal oxides, and transition metal chalcogenides, with their unique physical and electrochemical properties, are discussed. Various approaches to designing materials in the form of 0, 1 and 2D nanostructures and their effect of size and morphology on their performance as anode materials in LIBs are reviewed. Moreover, the article emphasizes smart approaches for making core-shell particles, nanoheterostructures, nanocomposites or nanohybrids with the combination of electrochemically active materials and conductive carbonaceous or electrochemically inactive materials to achieve LIBs with high capacity, high rate capability, and excellent cycling stability. We believe the review paper will provide an update for the reader regarding recent progress on nanostructured anode materials for LIBs. © The Royal Society of Chemistry 2015.

The polyetherimide/barium titanate (PEI/BaTiO3) nanocomposite films were successfully prepared by mixing the fine BaTiO3 particles into poly(amic acid) solution under ultrasonication followed by film casting and thermal imidization. Fourier transform infrared (FT-IR) spectroscopy, X-ray diffraction (XRD) and scanning electron microscopy (SEM) were used to characterize the structure and properties of the obtained nanocomposites. The dielectric properties of the PEI/BaTiO3 nanocomposites were analyzed in detail with respect to different experimental parameters like frequency, ceramic concentration and temperature. In comparison with pure polyetherimide, the dielectric constant of the nanocomposite (50 vol.% BaTiO3) was significantly improved by twelve times while the loss tangent only increased five times. The nanocomposites exhibited good dielectric stability over a wide range of temperature and frequency. Different theoretical approaches have been employed to predict the effective dielectric constant of the nanocomposite systems and, the estimated results were compared with the experimental data. The piezoelectric coefficients of the nanocomposite films were measured with varying ceramic volume fractions. © 2010 Elsevier B.V. All rights reserved.

This paper presents an analysis of regenerative Organic Rankine Cycle (ORC), based on parametric optimization using R-123 and R-134a during superheating at a constant pressure of 2.50 MPa under realistic conditions. The aim was to select a better working fluid on the basis of obtained system efficiency, turbine work output, irreversibility rate and second law efficiency under applied fixed and variable heat source temperature conditions. R-123 has been found a better working fluid than R-134 for converting low grade heat to power. A computer program has been developed to parametrically optimize and compare the system and second law efficiency, turbine work output, system mass flow rate, irreversibility rate and irreversibility ratio with increases in turbine inlet temperature (TIT) under different heat source temperature conditions to obtain the optimum operating conditions while using R-123 as the working fluid during superheating at various turbine inlet pressures for the utilization of the waste heat sources of temperatures above 150 °C. The calculated results reveal that an inlet pressure of 2.70 MPa gives the maximum system efficiency, turbine work output and second law efficiency with minimum irreversibility rate, irreversibility ratio and system mass flow rate up to a TIT in the range of 165 °C-250 °C. © 2012 Elsevier Ltd.

Agrobacteriumrhizogenes is a natural plant genetic engineer. It is a gram-negative soil bacterium that induces hairy root formation. Success has been obtained in exploring the molecular mechanisms of transferred DNA (T-DNA) transfer, interaction with host plant proteins, plant defense signaling and integration to plant genome for successful plant genetic transformation. T-DNA and corresponding expression of rol genes alter morphology and plant host secondary metabolism. During transformation, there is a differential loss of a few T-DNA genes. Loss of a few ORFs drastically affect the growth and morphological patterns of hairy roots, expression pattern of biosynthetic pathway genes and accumulation of specific secondary metabolites. © 2011 Springer Science+Business Media B.V.

Influence of Cr doping (5%) in ZnO lattice has been investigated in terms of modifications in electronic properties, evolution of defects and exploring their possible relationship with magnetic properties, using SQUID magnetometry and X-ray photoelectron spectroscopy (XPS). The Cr doping drives the diamagnetic ZnO host to a paramagnetic state, however, its post annealing in vacuum induces room temperature ferromagnetism (RTFM) in it that disappears by re-heating it in air. The findings infer a reversible ferromagnetic ordering in the Cr doped ZnO matrix. The XPS results indicate trivalent state of the Cr ions in the as-synthesized sample which tend to reduce to bivalency upon its vacuum annealing and also the evolution of oxygen vacancy defects have clearly been observed. The results indicate a close relationship of oxygen vacancies with the induced ferromagnetism. © 2011 Elsevier B.V. All rights reserved.

A mathematical model based on viscoelastic fluid (fractional Oldroyd-B model) flow is considered for the peristaltic flow of chyme in small intestine, which is assumed to be in the form of an inclined cylindrical tube. The peristaltic flow of chyme is modeled more realistically by assuming that the peristaltic rush wave is a sinusoidal wave, which propagates along the tube. The governing equations are simplified by making the assumptions of long wavelength and low Reynolds number. Analytical approximate solutions of problem are obtained by using homotopy analysis method and convergence of the obtained series solution is properly checked. For the realistic values of the emerging parameters such as fractional parameters, relaxation time, retardation time, Reynolds number, Froude number and inclination of tube, the numerical results for the pressure difference and the frictional force across one wavelength are computed and discussed the roles played by these parameters during the peristaltic flow. On the basis of this study, it is found that the first fractional parameter, relaxation time and Froude number resist the movement of chyme, while, the second fractional parameter, retardation time, Reynolds number and inclination of tube favour the movement of chyme through the small intestine during pumping. It is further revealed that size of trapped bolus reduces with increasing the amplitude ratio whereas it is unaltered with other parameters. © 2011 Elsevier Inc.

The effect of substitution of Zn by transition metal atoms Co and Mn (5%) in the host diamagnetic ZnO matrix was investigated using X-ray diffraction, magnetization and photoelectron spectroscopy. The dopant atoms incorporate at the Zn site in the hexagonal wurtzite structure without forming any impurity phases or cluster formation. The Mn atoms induce weak room temperature ferromagnetism in ZnO while the Co doping could drive it to only a paramagnetic status. However, the injection of H ions causes a giant ferromagnetism in Co-doped ZnO, on the contrary, the Mn doped ZnO does not respond to hydrogenation. Interestingly, the re-heating causes the H-induced magnetism to vanish in Co-doped ZnO, however, the Mn doped ZnO shows only a marginal sensitiveness towards re-heating. The switching action between ferromagnetic and paramagnetic states in ZnO:Co, by hydrogenation and heating, respectively, is a significant finding of this work. The experimental findings strongly suggest that the ferromagnetism in doped bulk ZnO might be associated with the O vacancies. © 2010 Elsevier B.V. All rights reserved.
