Abstract

In this work, Zinc Oxide nanoparticle was developed over reduced graphene oxide sheets and cyclic voltammetry was performed with different nanomaterial composites fabricated over electrodes and their graphs were compared. There was an exceptional rise in current, which shows that the composite could be used to catalyse different reactions, which favour transfer of electrons like Hydrogen Reduction Reaction and Oxygen Reduction Reactions. The graphene oxide (GO) was synthesised by improved Hummers method and it was reduced fully by treating it with by L-Ascorbic acid. The composite of Zinc Oxide Nanoparticles and Reduced Graphene Oxide was synthesised and characterised using different characterization techniques.

Abstract

In the present paper, the authors report their work on bio synthesis of silver nanoparticles by aqueous extraction of seeds of Phaseolus vulgaris. These synthesized nanoparticles are characterized by Uv-Vis Spectroscopy, Fourier Transform (FT) infrared spectrometry, Raman Spectroscopy, and XRD, and then evaluated for their corrosion inhibition potential for mild steel in acid media. The results show that the phytochemicals present in the seed extract of Phaseolus vulgaris can act as a reducing agent as well as capping agent for nanoparticles. Silver nanoparticles in the form of silver oxide were confirmed in the XRD study with the average size 15.75 nm and cubic in nature. Corrosion inhibition potential of these particles has been determined by mass loss method. Results show that these particles can inhibit rate of corrosion of mild steel in acid media if the uniform protective layer would be formed on the metal surface, and can be used in industries as a corrosion inhibitor. The Scanning Electron Microscopy image of the mild steel samples with and without Ag2O nanoparticles shows that there is adsorption of nanopaticles on to the metal surface in the presence of acid media.

Abstract

This paper investigates two areas that Graphene has shown potential in electronics; applications in existing electronics technology and applications in theoretical future biotechnology. The paper utilises research from scientific papers, reports, and journal articles supplemented by industry expert testimonies and a consumer survey. The paper then goes on to discuss how Graphene may enable the production of bio-inert Solution Gated Field Effects Transistors that could enable bidirectional interfacing between electronics and biological tissue, allowing neural interfaces that could allow products such as myoelectric prosthesis to be controlled naturally and provide natural sense feedback to the user. Finally, the paper looks at two current production methods; Micromechanical Cleavage and Chemical Vapour Deposition.

Abstract

This paper presents the study and analysis of data obtained through ECDM (Electro Chemical Discharge Machining) process. In the last few decades, it has been evidenced that design of experiment techniques have become more popular and a remarkable achievement on this has been accredited to Dr. Genechi Taguchi for his advent of these techniques providing the researchers with a valuable tool to use for all purposes according to the needs of the experimenter. The paper describes a case study on Electro chemical discharge machining process, used in machining fine micro-holes on borosilicate glass slides. The results of these experiments related to material removal have been analyzed using design of experiments technique, using the standard orthogonal array L9 and further these results have been computed through simulation using neural networks, i.e., Adaptive Neuro Fuzzy Interface System (ANFIS). The results suggest an error up-to 3.1% and it can be helpful to predict values within the experimental range and extrapolate the trends and in-between values.

Abstract

This paper deals with the study of materials and its impact on safety and temperature in the buildings. The materials considered for this study are multi layers; natural fiber, metal foil, sheet metal, and thermoplastics. The properties of the materials considered are varied depending upon the usage. The idea behind the selection of the materials is to regulate the temperature of the buildings. In the current scenario of the world, population is facing more environmental issues like global warming, green house effect, pollution, ozone depletion, etc. Humans suffer more due to rise in temperature, so they feel better even inside the house. To avoid such climate disaster, roofing system will be helpful. By taking actions for materials changes, it leads to perfect roofing system and it will provide benefit to the living people. These issues can be overcome by replacing alternate existing roof systems. The binominal difference from older roof system over this roof system is much preferable for more protective shelter. Now, people prefer only the popular roofing system like asbestos sheet metals that are safe and preventive, but they are always harmful than other roof systems. This paper have also discussed one of the alternate roofing systems with multi layer. The main objective of this multi layer low conduction roof is to maintain room temperature (25 oC - 29 oC) at any weather condition and it can block incoming harmful solar radiation from sunlight. These multilayer roofs are also suitable for industrial and residential areas.

Abstract

In the present paper, effect of cobalt (Co) substitution on dielectric behavior of Ba(Ti0.85 Sn0.15)O3 , which exhibits a broad maxima near room temperature in its ε' vs. T plots has been studied. Compositions with x = 0.01 and 0.03 in the system Ba(Ti0.85-x Cox Sn0.15)O3 were prepared by solid state ceramic method. Dielectric properties of the compositions were studied using Novocontrol α-S High Resolution dielectric analyzer as a function of temperature in the frequency range 1 Hz-1 MHz. Both the compositions (x = 0.01 and 0.03) exhibited a diffuse phase transition behavior similar to x = 0.00. Diffuseness of phase transition was determined by full width at half maxima (FWHM) in ε' vs. T plots. FWHM increases with increasing cobalt substitution. In hysteresis loop measurement, a decrease in coercivity and remanent polarization has been found with increasing Co concentration.

Abstract

This paper presents the surface morphological, optical and charge transport characterization of thermally evaporated thin film of organic material, namely 3, 5-Bis (4-tert-butylphenyl)-4-phenyl-4H-1, 2, 4-triazole (abbreviated as BBPT) prepared by well-known thermal evaporation technique, to be applied as an electron transport material in optoelectronic devices. Carrier mobility and AC conductivity are estimated from frequency dependent admittance -5 characterization performed over a single layer device having structure ITO/ BBPT /Al and are found in the range 5.17 x 10-5 cm2 V-1s-1 and 4.83575 × 10-6 ohm-1 m-1, respectively. Various electrical parameters are calculated from charge transport
characterization of ITO/ BBPT /Al device. Results of this work demonstrated that the conduction mechanism is in good correlation with the theory of hopping conduction in amorphous materials and the material studied have a potential application as an Electron Transport Layer (ETL) material in optoelectronic devices.
