High purity silica has been successfully synthesized from rice husk ash (RHA) by alkaline extraction using the reflux process followed acidification.For this study, was burned in an electric furnace at 700°C for 5 hours to produce RHA.The RHA refluxed sodium hydroxide with concentrations of 1.25×10 -3 M (equal 5% NaOH) and 2.5×10 10% NaOH).The acidification performed hydrochloric acid (HCl) 1 acetic (CH3COOH) 1M gel.Then, gel heated 120°C 12 produced silica.The characterization determined...
The Optimization of super alloy through alloying element composition control is very challenging since it contains more than ten type elements. Generally, the optimization process mechanical properties by alteration was performed via trial-and-error which time consuming and expensive. In this study, artificial neural network successfully employed to reveal correlation between hardness, tensile strength, melting point Ni based Fe–Ni alloy. model showed a good accuracy predicted actual values,...
Herein, Ag/TiO2 nanocomposite was synthesized via a green chemistry approach, which is an eco-friendly, simple, and cost-effective method involving mangosteen pericarp extract as reducing agent. The as-prepared nanocomposites were characterized using X-ray powder diffraction (XRD), Fourier transformation infrared spectroscopy (FT-IR), UV-Vis spectrophotometer, Scanning electron microscopy (SEM), Energy dispersive (EDS), Transmission (TEM), Zeta potential measurement, nitrogen (N2)...
. This waste can be used for environmental purposes, such as the treatment of colorants in textile industry using mesoporous silica materials. Previous studies showed potential synthesizing from agricultural including corn cob and rice husk. Therefore, this study aimed to investigate use sugarcane bagasse an alternative source silica. Sugarcane ash, containing a high content ranging 55.5% 70%, served main synthesis. A combination surfactant templates, Pluronic 123 (P123), Cetyl Trimethyl...
The power conversion efficiency (PCE) of a dye-sensitized solar cell (DSSC) device depends on its semiconductor characteristics. Titanium dioxide (TiO
A356-matrix composites are used in many areas such as transportation, automotive, and food industries because of its light weight, ductility, the ability to improve mechanical properties. One most often problem making is relatively high amount ceramic particles tends segregate aluminum matrix. So, order overcome this problem, little used. In work, casting was conducted via stir method by various additions 0.05%, 0.10%, 0.15%, 0.20%, 0.25% volume fraction nano silicon carbide (SiC). 0.046 wt%...
Hydrogen is one of the future energy because it enviromentally friendly. However, there still some problem in storage method hydrogen.

Silica nanoparticles (SNPs) have many important applications including anti-reflection coating, self-cleaning surface and drug carriers. They are usually synthesized from the commercial precursor such as tetraethyl orthosilicate (TEOS). On other hand, natural silica can be found abundantly in organic materials rice husk palm shell or inorganic material beach sand clay. Therefore, obtaining SNPs resources is very strategic for economic technology considerations. This motivates current study...
