Purification water is used in many industries, such as power plants, refineries, and manufacturing for cooling the system to regulate the temperature and prevent equipment from overheating. Many chemicals process purified water as a solvent, diluents, or medium to carry out reaction without contamination. In some industries, it is used to mix with chemicals in processes. Purified water is used to clean the machinery, tools, and equipment in industries like pharmaceuticals, food, beverage and electronics fields. In some industries, like energy production, purified water is used in boilers to generate steam for power production. Various methods are available for converting saline water into purifying water. Those methods are such as desalination, vapor compression, reverse osmosis and electro dialysis. Solar water desalination is one of the most popular solar technologies. In this technology, the pure water is produced without salt content from the salty water including the bore water and seawater. A solar still is used and stores solar energy. A single basin, a single sloped solar still with a cover angle of 45 degrees covering a depth of 25 mm bore water level in the basin. Solar energy is no polluting energy and also a free renewable source of energy. Cuddappa stone is used to construct the solar still, and thermocol insulation is used to cover it in this work. Adding certain heat-absorbing materials to the solar still basin and boosting its efficiency while enhancing the rate at which bore water is purified. To assess the performance, the solar yield rate should still be compared to that of various energy-absorbing materials, such as steel balls, tin pieces, and lead balls. The steel ball gives a higher production rate than the rest of the energy materials. The maximum day yield efficiency of a solar still is 11 %, while the maximum day yield of steel balls dyed black is 1770 ml/m2/day. The lowest dayyield efficiency of a solar still without energy materials is 3 %, and its minimum daily yield is 490 ml/m2/day.
Chitosan-metal oxide nanocomposites are prospective multifunctional components with their biocompatibility and adjustable properties. The present paper describes the easy preparation of a nanocomposite made of chitosan and antimony trioxide (Sb _2 O _3 ) by modified ionotropic gelation and the accompanying physicochemical, thermal, mechanical, and biological observations. SEM, TEM, and AFM microscopy demonstrated consistent spherical particles with a diameter of ∼180 nm, and EDX, FTIR, and XRD spectroscopies indicated highly active polymer-metal interactions and the achievement of the composite. In TGA analysis, the Nanocomposites showed significant improvement in thermal stability, better glass transition temperature, and a slowdown in decomposition after being dip-coated onto glass fibers. The mechanical tests demonstrated that the nanocomposite performed better than pristine chitosan as well as Sb _2 O _3 in terms of hardness, tensile strength, flexural strength and wear resistance, which envisaged the superior structural integrity of the sample and prolonged its durability. Flame resistance applications demonstrated an optimum reduction in burning rate at a level of 3 wt% composite loading. Also, the nanocomposite displayed dose-dependent antibacterial action against Bacillus subtilis, Staphylococcus aureus and Pseudomonas aeruginosa , which were more effective than the individual components. These findings show promise of the use of chitosan-Sb _2 O _3 nanocomposites in thermal-protective, antimicrobial and structural applications, especially in coatings, textiles, and biomedical materials.
Renewable energy sources (RES) are crucial to the generation of electrical power, especially for grid-connected systems. When RES is integrated with a grid, power quality issues such as voltage sag, swell, and harmonics, affect the consumers. To overcome these issues, this paper presents the intelligent control algorithm-based Finite Control Set Model Predictive Control (FCS-MPC) strategy for an electrical grid-connected photovoltaic-wind hybrid energy system with DPFC (Distributed Power Flow Controller). For controlling FCS-MPC, Egret Swarm Optimization Algorithm (ESOA) algorithm is utilized to select the values required for the control operation. This work aims at mitigating PQ issues and compensating for power demand in HRES. This research proposes an ESOA-based FCS-MPC technique (ESOA FCS-MPC) with DPFC with real and reactive power to address PQ concerns in HRES systems. The proposed work is tested with the MATLAB/Simulink tool, and compared with the existing conventional PID controller, FOPID controller, and BWO-Based FOPID Controller based DPFC system. Based on simulation results, DPFC can improve the quality of the power and reduces the THD current and voltage value by 0.86 and 0.49%, respectively.
