The proportions of coarse aggregate, superplasticizer, and alkaliactivated solutions used in the geopolymer concrete mixes were 1189 kg/m 3, kg/m 3, and 171 kg/m 3, coarse aggregate and water used in the conventional concrete mix were 1189 kg/m 3 and 171 kg/m 3, Table 3, it is observed that G20M0 indicates that the mixes have 20% GGBS, 80% fly ash, and 0 ...
Sub100 nm hollow carbon nanospheres with thin shells are highly desirable anode materials for energy storage applications. However, their synthesis remains a great challenge with conventional strategies. In this work, we demonstrate that hollow carbon nanospheres of unprecedentedly small sizes (down to ∼ nm and with thickness of ∼ nm) can be produced on a large scale by a ...
for over 70 years. By the early 1940's, precipitated and fumed silica nanoparticles were being manufactured and sold in USA and Germany as substitutes for ultrafine carbon black for rubber reinforcements. Nanosized amorphous silica particles have found largescale applications in many everyday consumer products, ranging from

With silica contents above %, there's little room for impurities in our fine ground silica. That means our products will reflect well on you. Choose from five different grades from 5 to 40 micron topsize with some of the industry's narrowest size distributions. Featured Product.
Biobased polyurethane (BPU) has been developed using a castor oil/poly(εcaprolactone) hybrid polyol, and hydrophobic BPU ultrafine fibers containing modified silica (msilica) were successfully fabricated using an electrospinning process. The successful modification of the silica nanoparticles and the synthesis of BPU composites were confirmed by Fourier transform infrared spectroscopy data ...

Silica (SiO2) content also controls the minerals that crystallise and is used to further classify igneous rocks as follows: Acid: rocks with above 63% silica (mostly feldspar minerals and quartz), granite. Basic: rocks that are about 45 to 55% silica (mostly mafic minerals plus plagioclase feldspar and/or feldspathoid minerals), basalt.
