Numerous agricultural wastes are well-defined as low-cost sources and rich in silica content. The residue of oil palm wastes combustion seems a promising silica source and can be recovered through a straightforward method. In this study, the combustion fo... see more

The sliding behavior of an amorphous silica sample between two rigid surfaces is in the focus of the present paper. Molecular Dynamics using a classical Tersoff’s potential and a recently developed ReaxFF potential was applied for simulating sliding... see more

This study aims to determine the composition of the oxide, the characteristics of palm shell and coir, and silica gel synthesized. The oxide composition, crystallinity, palm shell and coir ash functional groups were analyzed using XRF, XRD, and FTIR. Anal... see more

Abstrak. Penelitian ini bertujuan untuk mengekstraksi dan memunikan silika dari abu sekam padi (ASP) dan melihat karakteristik silika yang dihasilkan apabila diberi perlakuan sonikasi dan refluks. Metode yang digunakan dalam penelitian ini adalah sol-gel ... see more

Using molecular dynamic simulation, we developed an algorithm to protonate the surface of an amorphous porous silica grain particle model and study its effect. In this work, the silica grain model can be used to study cosmic dust coagulation. The surface ... see more

Combustion of corn leaf as a model of biomass from agricultural waste is a simple way to obtain the energy. It produces a low-value by-product of ash and is rich in silica that can become a precursor for zeolite production. In this study, acid-treated cor... see more

Green synthesis of silica nanoparticle from cow dung ash is a promising prospect due to the low-cost and environmental friendliness coupled with the ability to manipulate its physicochemical properties. Silica nanoparticles yield of around 76% was obtaine... see more

In this research, adsorption of Ca(II), Pb(II) and Ag(I) in aqueous solution onto sulfonato-silica hybrid (SSH) prepared from rice hull ash (RHA) has been studied. The preparation of SSH adsorbent was carried out by oxidation of mercapto-silica hybrid (MS... see more
