In this paper, we developed a single-step sol–gel-hydrothermal method to synthesize novel mesoporous crumpled paper-like silica balls with a relatively large surface area of 602 m 2 g −1 and high pore volume of 0.97 cm 3 g −1.XRD, FT-IR, FE-SEM, TEM, TGA-DTA, and N 2 adsorption–desorption techniques were used to characterize …

Amorphous silica powder (SO-C1, Admatechs, , Japan) was used to prepare modified silica. The average diameter was 230 nm and a specific surface area of 16.2 m 2 /g measured using the Brunauer-Emmett-Teller method. Twenty grams of silica powder and 250 g of zirconia balls with a diameter of 5 mm were placed in a 250 ml …

Taking the FLM as the projectile ball and the WLM as the other target balls, one can adjust the displacement and direction of the WLM precisely, similar to an expert billiard player.

And yes, it means "dry.". Silica gel is a dry gel. All gels — toothpaste, pudding, some would say your heart and lungs — start out as tiny particles floating in liquid. Under the right conditions the particles fuse together. They form a 3-D structure that holds the liquid in and gives it shape — even if that shape is a bit squishy.

In this study, silica powder was modified using a mild ball milling procedure with HTMS. Sufficient pulverization or temperature rise was not observed. Two important …

In this work, golf ball-like thiol-functionalized silica particles were synthesized for the first time by a one-step sol-gel reaction using 3-mercaptopropyl trimethoxysilane (MPTMS) and tetraethoxysilane (TEOS) as the precursors. The particle growth with time was monitored by SEM and a particle formation mechanism was proposed.
