The sol gel process is one of the processes used in the manufacture of thin films on membranes because it can control the pore size in the resulting silica matrix. In addition, another way to build membrane size can be done by adding catalysts and precurs... 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

In this study, silica gel was extracted from rice husk ash using a modified acid-leaching process. The gel was then characterized using an X-ray Diffractometer (XRD) and an X-ray Fluorescence (XRF). At different loadings of 0, 0.05 and 0.10 wt.%, sil... see more

Research on the synthesis of mesoporous silica catalyst, as well as its activity and selectivity in the hydrocracking of used palm oil, has been carried out. The research involved the preparation of mesoporous silica catalyst by varying the volume ratio o... see more

This paper investigates the flexural behavior of high-strength RC beams experimentally to assess the effect of Nano-silica (NS) and Macro-Synthetic High Strength Polypropylene Fiber (MPF). Ordinary Portland cement was partially replaced by the NS and MPF ... see more

This study aims to find the optimum conditions for the adsorption of Cr (VI) ion to the eugenol-silica gel composite as an adsorbent and to determine the adsorption parameters using the Langmuir and Freundlich isotherm model. The three optimization parame... see more
