Rice Husk Ash-Derived Silica Nanofluids: Synthesis and Stability Study
Nanofluids, colloidal suspensions consisting of base fluids and nanoparticles, are a new generation of engineering working fluids. Nanofluids have shown great potential in heat/mass transfer applications. However, their practical applications are limited by the high production cost and low stability. In this study, a low-cost agricultural waste, rice husk ash (RHA), was used as a silicon source...
متن کاملNanocellulose from Rice Husk following Alkaline Treatment to Remove Silica
The present work deals with the use of multiple-step procedures to obtain valuable sub-products, including nanocellulose, from rice husk. Each sub-product was characterized after every step by analyzing the chemical composition (mainly based on thermogravimetric analysis, Fourier transformed infrared spectra, and X-ray diffraction) and morphology (using visual observations and scanning electron...
متن کاملReinforcement of natural rubber hybrid composites based on marble sludge/Silica and marble sludge/rice husk derived silica
A research has been carried out to develop natural rubber (NR) hybrid composites reinforced with marble sludge (MS)/Silica and MS/rice husk derived silica (RHS). The primary aim of this development is to scrutinize the cure characteristics, mechanical and swelling properties of such hybrid composite. The use of both industrial and agricultural waste such as marble sludge and rice husk derived s...
متن کاملKernels from hulls
The kernel of a polygon has long been an object of study in computational geometry, especially in the context of art gallery theorems. In this paper, we present two new algorithms for computing the kernel of a plane curve. We show that the computation of the kernel of a plane curve can be reduced to the computation of the convex hull of a plane curve, revealing the computational and structural ...
متن کاملSynthesis of Si/MgO/Mg2SiO4 Composite from Rice Husk-Originated Nano-Silica
Silica exists in Rice husk, an agriculture waste, as a naturally occurring phase. In first step, acidic pre-treatment and calcination of the rice husk were performed to obtain nano-silica, in which various sizes of the nano-silica, totally with sizes under 80 nm, were achieved. Second, to reduce nano-silica to elemental Si and subsequently formation of the composite, Mg used as the reducing age...
