“…According to Li et al, 20 solvothermal process is defined as performing chemical reactions in solvents under specific temperature. Matei et al 21 also stated that solvothermal synthesis can be easily performed under controlled condition as ZnO NPs can be synthesized into different morphologies depending on the reaction conditions.…”

“…Besides, solvothermal synthesis is considered one of the most promising approach to synthesize NPs. 20 In solvothermal synthesis, organic solvent mainly alcohol such as ethanol as being used by previous researchers to synthesize ZnO NPs. 4,23,24 Furthermore, NPs characterization using XRD, TEM, BET, EDX, FT-IR spectroscopy, and UV-Vis spectroscopy are fundamental steps especially for examining NPs surface properties and functionality.…”

Solvothermal synthesis has shown to have a great potential to synthesize Zinc Oxide nanoparticles (ZnO NPs) with less than 10 nm size. In this study, we present a rapid synthesis of ZnO NPs in which ZnO NPs with more uniform shape and highly dispersed were synthesized using zinc acetate dihydrate (Zn(CH 3 COO) 2 2H 2 O) and potassium hydroxide (KOH) as a precursor and absolute ethanol as solvent via solvothermal method. Few techniques were exploited to characterize synthesized ZnO NPs including X-ray diffraction (XRD), transmission electron microscope (TEM), Brunauer-Emmett-Teller (BET), energy-dispersive X-ray spectroscopy (EDX), fourier transform infrared (FT-IR) spectroscopy, and ultraviolet visible (UV-Vis) spectroscopy. Synthesized ZnO NPs that were prepared via solvothermal synthesis method at 60 °C for 3 hours exhibited a wurtzite structure with a crystalline size of 10.08 nm and particle size of 7.4 ± 1.2 nm. The UV-vis absorption spectrum has shown peak at 357 nm indicate the presence of ZnO NPs. Hence, better quality with uniform size ZnO NPs can be easily synthesized with reduced amount of time via solvothermal synthesis method rather than using other complicated and lengthy synthesis methods.

“…The instruments used in the Solvothermal/Hydrothermal process include a sealed reactor (autoclave), a pressure vessel, or a high-pressure bomb. The autoclave is usually metallic with Teflon or alloy linings or containing an extra beaker, or tube made of Teflon, platinum, gold, or silver to protect the autoclave body from highly corrosive solvent held at high temperature and pressure [6]. The Solvothermal/ Hydrothermal process uses crystallization to grow particles from the solvent.…”

Heat-generating equipment (such as transformers, computer microchips, car engines, nuclear reactors, etc.) requires an efficient cooling mechanism to safeguard them from thermal degradation and to enhance their life span. The use of Nanofluids as opposed to conventional heat transfer fluids in their cooling system is to ensure that they are properly cooled. Nanofluids display superior thermal properties and they are synthesized from nanosized materials such as metals ((Copper (Cu), Silver (Ag), Nickel (Ni), and Gold (Au)), metal oxides (( Aluminum oxide (Al2O3), Cupric oxide (CuO), Magnesium oxide (MgO), Zinc oxide (ZnO), Silica (SiO2), Iron (III) oxide (Fe2O3), and Titania (TiO2)), metal carbide (such as Silicon carbide (SiC)), metal nitride (such as Aluminium nitride (AIN)), or Carbon materials ((Carbon nanotubes (CNTs), Multi-wall carbon nanotubes (MWCNTs), diamond, and graphite)) suspended in base fluids (such as water, ethylene glycol, engine oil, transformer oil, vegetable oil, kerosene, toluene, etc.). The current review explores methods used in the synthesis of nanofluids (One-step method, Two-step method, Solvothermal/Hydrothermal process), factors influencing their thermophysical properties (Particle volume concentration, pH, particle size, particle shape, particle material, base fluid material, temperature, shear rate, and surfactants) and their applications (Heat transfer applications, automotive applications, biomedical applications, electronic applications, Nano-based microbial fuel cells, and Nano-based brake fluids).

“…In the perovskite structure, the cations can fit into both the A and B sites [11]. These perovskites were blended using various methods such as hydrothermal [12][13][14], co-precipitation [15][16][17], sol-gel [18,19]. Among these methods, the sol-gel method has been viewed and appreciated by various researchers due to excellent quality of the resulted nanomaterials.…”

The present work emphasizes the effect of the use of Sn, with different concentrations, over the structural properties and sensing applications of LaCrO 3 . In this work, LaCrO 3 nanostructures were modified with different concentration of Sn (0.2 M %, 0.4 M %, 0.6 M % and 0.8 M %).Different modified Sn-doped LaCrO 3 was synthesized by sol-gel method and followed by preparation of thick films via a conventional screen printing approach. The characterizations done by means of X-ray diffraction (XRD), energy-dispersive X-ray (EDX), scanning electron microscopy (SEM) and transmission electron microscopy (TEM) revealed the confirmation of a Sn-doped LaCrO 3 crystal structure and its morphology, respectively. These oxides were formulated to identify various air pollutants such as CO 2 , ethanol, H 2 S, NH 3 , NO 2, and acetone. The Sn-doped LaCrO3 with 0.4 M % Sn displayed higher gas response to ethanol vapor at the range of 150-250 °C. The sensors additionally demonstrated proper recovery and acceptable stability. Graphic abstractThe graphical abstract demonstrates the in situ synthesis of Sn-doped LaCrO 3 by sol-gel method. Similarly, it shows its characterization and finally, the thick films of doped Sn demonstrate best selectivity for ethanol.Open Access This article is distributed under the terms of the Creative Commons Attribution 4.0 International License (http://creat iveco mmons .org/licen ses/by/4.0/), which permits unrestricted use, distribution, and reproduction in any medium, provided you give appropriate credit to the original author(s) and the source, provide a link to the Creative Commons license, and indicate if changes were made.
