The base polymer properties have been developed experimentally by adding small amounts of different fillers but they are expensive to the polymer material. Thus, it has been investigated that the incorporation of cost-less nanoparticles like clay and fumed silica nanoparticles into low density polyethylene LDPE and high density polyethylene HDPE which controlled the breakdown strength and volta...

An in-depth investigation into the synthesis of hydrophobic silica aerogels prepared by the surface derivatization of wet gels followed by subsequent drying at ambient pressure is reported. The following sol-gel parameters were examined for their effect on the physical properties of the derived aerogels: number of gel washings with water, percentage of hexane or methanol in silylating mixture, ...

Strain-rate-dependent mechanical properties and impact performance of manufactured epoxy-based nanocomposites are investigated. As reinforcements, fumed silica (FS) halloysite nanotube (HNT) used alongside Albipox 1000 Nanopox F700. First, the internal structures composites visualised using scanning electron microscopy (SEM). To identify strain-rate-dependent properties, three-point bend tests ...

Developing a novel and facile way to synthesize composite aerogels plays an important role in the applications of aerogels. UV-resistant hydrophobic titania-containing silica aerogels are prepared for the first time using potassium titanate as precursor by a modified ambient pressure drying method. The well established silica-titania networks, which can be tuned from 10 to 30 nm by adjusting th...

Effective silica coating on hydrophobic quantum dots (QDs) was achieved by ultrasonic fragmentation of lipophilic silane-QDs precusor into water-soluble micelles and subsequent silicate deposition. This method allowed high retention of QD fluorescent properties and an easy scaling over the size and loading amount of silica beads.

Intracellular glutathione-triggered doxorubicin release from silica nanotubes with hydrophobic labile cap was demonstrated for the drug-resistant cancer cell treatment.

The first successful approach to synthesizing ultrabright fluorescent mesoporous silica nanoparticles is reported. Fluorescent dye is physically entrapped inside nanochannels of a silica matrix created during templated sol-gel self-assembly. The problem of dye leakage from open channels is solved by incorporation of hydrophobic groups in the silica matrix. This makes the approach compatible wit...

Fused silica glass is a commonly used high-performance material. However, due to the high temperature necessary for its production, manufacturing can also be challenging and costly. An attractive approach additive through laser cladding. Laser cladding of transparent fused was achieved using CO 2 -laser locally melt substrate while injecting stream fumed powder into melt-pool. By described tech...

Abstract Fumed silica-filled polypropylene (PP)-based nanodielectrics were studied in this work. To not only improve the dispersion of silica but also introduce deep charge traps into polymeric matrix, five types modified silicas manufactured with different surface modifications. The surfaces comprise an inner and a layer. layer contains polar urethane group for tailoring trap properties PP/pro...
