I used to toss those silica beads in the trash, but my brilliant husband asked me to start keeping them. He has discovered some great uses for those silica gel packets that I had never thought of! MY LATEST VIDEOS What is silica gel? What is silica used for? Silica gel packets are us...
Sugarcane ash was collected in December 2019 from the Ingenio San Antonio-Nicaragua sugarcane field near Leon, Nicaragua. SiNPs were derived from SA using a method previously utilized and briefly described below [47]. Pristine homogenous nano-sized (200 nm) SiNPs were purchased from nanoComposix/...
When PPO segments are substantially aggregated, they cause dramatic changes in the storage (G′) and loss (G″) moduli of the HMP solution, indicating transition from a near-Newtonian liquid to a viscoelastic gel [137]. Sign in to download full-size image Fig. 11. Differential scanning ...
hand, the hard template method has also been used. This method is based on the use of polymer beads such as polystyrene (PS) particles and metal or oxide nanoparticles. Finally, an aerosol-assisted synthesis method has also been described [115]. The unique characteristics of mesoporous silica ...
The method involves prehydrolysing alkoxysilanes and atomizing to droplets which are then cured to hardened beads with no or very low porosity and narrow size distribution by slurrying with aqueous ammonia. The cured beads are mixed with binders and the resulting pastes are compacted to green form...

A superhydrophobic surface with a water contact angle higher than 150° can easily be fabricated because of the roughness created by submicron-sized polymer beads. However, this type of micropapillae roughness formed by the solid polymer can be easily damaged by physical touch, and therefore, ...
In particular, the ageing of gel is one of the key steps to ensure the maturity of the gel network, in which the condensation reaction is completed. The environmentally benign depolymerization reaction of silicate network and RHA in the presence of glycerol near 200 ◦C was reported [14]. ...
