The existence of bamboo plants is very much in Indonesia. The part that is mostly used is the stem, while the leaves are left to become waste. Even though the silica content in bamboo leaves is quite high. Research on the synthesis of nanosilica from bamb... see more

Biodiesel synthesis from neem oil and methyl acetate using lipase catalyst immobilised in nanosilica particles in a continuous inverse fluidised bed bioreactor of modified design has been analysed. The process has been simulated mathematically by developi... see more

Desire to improve the efficiency of composite materials for engineering applications has led to the use of nano-sized additives or fillers such as nanoclay, nanosilica, nano-graphene, carbon nanotubes. The effect of nanoparticle inclusion on mechanical pr... see more

The present research work is carried out using the experimental study to evaluate the concrete made with Aggregates of the Quarry with Addition of Nanosilica containing micro-fine nanoparticles of amorphous silica dioxide (Si O2). Nanosilica has pozzolani... see more

Energy supply has been one of the world’s main problems. Thus, the development of new energy and renewable energy resources can be a promising solution. As one of the promising energies from biomass is bio-methane obtained from biogas purification. Membra... see more

Heavy metals are considered hazardous to health if they accumulate excessively in the body. One way to remove iron metal ions by adsorption process uses adsorbents. In this study, removal of heavy metals such as ferrous metal (Fe) was adsorbed using an ad... see more

This comparison study focuses on the impacts of using nano-silica (nS) on chemical attack resistance of self-consolidating concrete (SCC) and its effectiveness in comparison to similar replacement levels of the more widely employed micro-silica (mS). Two ... see more

Polyethylene (PE) has been widely used as the insulation material of high voltage cables because of its outstanding physical, chemical, and electrical properties. In this research the amorph nanosilica powders were extracted from pumice using NaOH, H2SO4 ... see more

The investigation of effect NaOH in extracting nanosilika from pumice has been carried out. The aim of research is to study the effect of variation NaOH against the amount and chemical compositions of nanosilica extract results. The extraction process is ... see more
