Abstract
Nanocomposites are commonly used as fillers with size at the nanoscale and have low loading, have the potential to match or significantly improve performance to supply conventional composites. Graphene oxide (GO), an oxidative exfoliating product of natural graphite, has attracted much attention due to its excellent strengthening effect on polymers. Young modifications of the GO sheet and the strong interaction interface between GO and the matrix polymer. Therefore, graphene oxide is expected to offer a promising nanoscale for the next generation of nanocomposite materials. Besides that, silica precipitate a critical materials used in many applications worlwide. Silica Precipitates have become key fillers in nanocomposites due to their properties which can improve mechanical properties. In this study, Chitosan-based Nanocomposite Films have been made by casting methods. The effect of graphene oxide and silica precipitates on the chitosan film and their properties were investigated. Graphene oxide used in this study was synthesized with chemicals from pure graphite using the Hummer Method. Graphene oxide produced from the hummer method was characterized by X-Ray Diffraction and Scanning Electron Microscope. Silica precipitates in this study uses cristobalite phase of silica. The measurement results of the mechanical properties of nanocomposite films show that adding christobalite phase of silica precipitate content in composites increases the tensile strengh of 21.3 Mpa and higher than addition of GO in the chitosan films. Meanwile, addition of GO in chitosan film increases the young modulus up to 2.73 Gpa.

Abstract
The Kamijoro Dam is very useful to support increased agricultural production, especially to strengthen food self-sufficiency and supply of raw water. The authors redesigned the Kamijoro dam. Based on observations, there is a dam potential to increase its capacity and function by first redesigning the initial planning. In order to redesign the Kamijoro dam, value engineering analysis was applied. The value engineering results are compared with the initial design to obtain a better, more effective and efficient dam design. The way to compare it is to use the evaluation matrix method. From the planned peak length of the dam 161 meters, dam discharge of 13.171 m3 / sec / m1, the fulfillment of raw water is 500 l / s with a project value of Rp. 188.799.932.000,-.

Abstract
Lithium barium borate glasses of composition defined as series I : 30 Li2O - X BaO - (70 – X) B2O3 (where X = 0, 5, 10, 15 and 20 mol %) and series II : (30 – X) Li2O - X BaO - 70 B2O3 (where X = 0, 5, 7.5, 10, 12.5 and 15 mol %) have been studied for their density, the coefficient of thermal expansion, CTE, glass transition temperature, Tg and electrical conductivity. An attempt is made to correlate the observed variations in these properties with the Li+ ion content, mass and the field strength of the Ba2+ cations and corresponding changes in the network. The studied glasses offer a very good range of CTE (72 - 112 x 10−7 / K) and could be developed as electrical insulators on account of their poor electrical conductivity..

It’s noteworthy to state that we are the first one to report novel complexes based on Ba (Baq2 and Mg0.5Ba0.5q2). The inquisition of these complexes was carried out to probe structural, photo physical and photometric parameters by FTIR, photoluminescence (PL) spectra and 1931 CIE colour calculator, respectively. These investigations reveal that pH value and stoichiometry have feeble effects on the emission wavelength and intensity. Investigations further reveal that among all the synthesized complexes, Baq2 (at pH 6.5) emits intense blue light in various environments. Thus, barium based quinoline complexes have the potential to sustain their emission features in solid state as well as in acidic and basic medium-one of the characteristic features which are highly essential for the fabrication of OLEDs by vacuum as well as solution techniques.

The spectroscopic properties of synthesized phosphor were observed by photoluminescence and photometric characterization technique. The obsearved excitation spectra revealed two bands around 395nm and 466nm that was attributed to the 7F0→5L6, and 7F0→5D2, transition oftrivalent europium ions, respectively. Under 395nm and 466nm excitation, the PL emission spectra shows several emission bands around at 580nm, 593nm and 613nm, which are ascribed due to 5D0→7F2, 5D0→7F1, and 5D0→7F2 transition of Eu3+ ions, respectively. The emission band of 613nm indicates the highest emission intensity compared to the other emission bands. The emission band revealed the highest emission intensity at 1mol% concentration of Eu3+ ions. Further, a CIE chromaticity diagram was obtained, which is confirmed that red emission. The entire investigation and their outcomes revealed that the synthesized phosphors exhibit strong red emission, which can be applied in the lighting industry and display applications.

Published: June 2021

Abstract
The Samples of Cobalt-Zirconium doped Barium nano-hexagonal ferrites of chemical formula BaFe12-2x(Zr-Co)xO19 (x = 0.5, 0.9) are prepared employing Microwave assisted Sol-gel auto-combustion Route, in which the ferrite materials were generated by providing continuous heat in microwave woven. The precursors in the form of nitrates are taken accompanied with urea as a fuel, supply energy to initiate exothermic reaction during the formation of materials. Uniform heating in the microwave leads to the ultrafast morphological transformations giving rise to a nano-scale particle size of the synthesized samples. The derived ferrites powders being analyzed for their structural and morphological characteristics with the help of X-ray diffraction techniques (XRD) and Transmission Electron Microscopy (TEM). Lattice constants ‘a’ and ‘c’, porosity (p) of the prepared materials were determined. Their d-values are counter checked and (h k l) planes were specified. TEM analysis confirmed the nano-scale particle size of the synthesized samples. The materials have been assessed with Impendence Analyzer for electrical resistivity (ρ). The obtained results suggest that the synthesized samples belong to the family of hexagonal M-type ferrites. A structural observation has verified that the space group symmetry of the prepared materials is P63/mmc. The ferrites samples show high resistivity of the order 107 (Ω-m). Such types of nano-sized ferrite materials with high resistivity are helpful especially for various microwave absorbing applications.

Abstract
In India, the construction activities are increasing day by day and as a result, the natural sand has become scare and costly material. To meet this increase in demand one has to go for excessive mining of river bed and that leads to natural imbalance. Therefore reducing the consumption of natural sand in construction is a major issue considering both the environment and economic issues. To balance the demand one has to go for sustainable unconventional innovative materials and particularly the industrial by products where there mass disposal and solid waste management is the problem. Copper slag is one of the industrial by-product obtained during manufacture of copper. This paper presents the experimental results on concrete made of copper slag. Mechanical properties like compressive strength, abrasion resistance and durability properties like acid resistance were carried out. The test results shows the concrete containing copper slag as fine aggregate has good strength and properties and the copper slag replacement level can be limited to 40-60% (by weight).

Abstract
Charging of energy storage system using flat plate solar collector (FPSC) is very popular in recent years. FPSC for the thermal energy storage system (TESS) using hybrid nanofluid was discussed in this manuscript. Hybrid nanofluid of CuO+ Al2O3/water was used as heat transfer fluid (HTF) for solar collector which is coupled with thermal storage and analysis carried out. To predict the thermal performance of energy storage system using hybrid nanofluid, a stainless steel container was used for thermal storage. CuO+Al2O3/water hybrid nanofluid were used to investigate the thermal performance of the solar collector and energy storage system. The FPSC is used for experimental investigation on the stainless steel container TESS. The flat plate solar collector is found more efficient than the other conventional type solar collector using hybrid nanofluid. The temperature of stainless steel container thermal energy storage system was reached to 87°C by using hybrid nanofluid in FPSC.
