New types of energy storage are needed in conjunction with the deployment of renewable energy sources and their integration with the electrical grid. We have recently introduced a family of cathodes involving the reversible insertion of cations into materials with the Prussian Blue open-framework crystal structure. Here we report a newly developed manganese hexacyanomanganate open-framework ano...

Biofilms are made of biopolymers. In the casting technique, biofilms are obtained by the drying of a polymer suspension in the final stage of processing. The aim of the present paper was to analyze the effect of this drying process on the mechanical properties of films produced with amaranth flour. Variables considered include glycerol content (30, 35 and 40%, g/g dry flour) and air-drying cond...

In this report, a model of external cavity semiconductor laser is built, and then based on this model a program is coded for simulating the thermally induced wavelength shift and mode hopping. By comparing the simulation and the published experimental results of two modified ECL designs we found that our simulation results agree very well with the experimental results. Through theoretical analy...

Polygalacturonases (PGs) are pectinolytic enzymes with wide industrial applications. The demand for the enzyme and its producing organism is rapidly increasing. Enzymes from filamentous fungi have been subject to vast number of studies due to their functional role in the organism as well as their advantage as models for enzyme production and their characteristics. The objective of the study was...

Two phase flow in a horizontal tube has widespread applications, particularly in the condensers of refrigeration and air conditioning systems. Pressure drop prediction is especially important for condensers because the local condensing temperature is a function of local pressure, affecting the mean temperature difference in the heat exchanger. In the present analysis, two phase flow is treated ...

Garments washing is a novel process to impart worn-out look, to modify the appearance and to improve the comfort ability of the garments. Bleach wash is used to fade the color of denim in a higher degree as well as bleach wash has effect on the physical and mechanical properties of the denim also. This paper presents the impact of bleach wash and subsequent softening treatment on 100% cotton de...

The crystal structure and Li storage properties of Cu-doped rutile TiO2 after a phase change caused by lithiation were investigated for the first time. Structural analysis results confirmed that undoped was transformed to distorted layered rock-salt LixTiO2 with small volume expansion only 1 % when cycled in potential range 1.0–3.0 V vs. Li+/Li. A substitutional solid solution Cu2+ formed LixTi...

Size tunable Cadmium sulphide (CdS) quantum dots have been synthesized through wet chemical co-precipitation method, at three different temperatures 35C, 50C and 65C for varying pH values of 9 and 10.5 respectively. The solution was prepared using Cadmium chloride and thiourea as material precursors, ammonium hydroxide as precipitating agent and mercaptoethanol as surfactant. Thin films of thes...

Plants of genus Leucas belongs to family Lamiacae and have been widely employed by the traditional healers to cure many diseases. The objective of the study was to do preliminary phytochemical screening of Ethanolic Extract of Leaves of Leucas indica (EELLI). About 1000 gm of air dried powdered material of leaves of Leucas indica was extracted with 90% ethanol in a soxhlet extractor for 36 hour...

High-performance Li-ion batteries require materials with well-designed and controlled structures on nanometre and micrometre scales. Electrochemical properties can be enhanced by reducing crystallite size and by manipulating structure and morphology. Here we show a method for preparing hierarchically structured Li4Ti5O12 yielding nano- and microstructure well-suited for use in lithium-ion batte...
