Influence of various processing parameters on water-glass-based atmospheric pressure dried aerogels for liquid marble purpose

Electrically Deformable Liquid Marbles

“…The measured and calculated according to (4), (5) dependencies of r on E are compared in Figure 5. The constant A=0.017 (in cgse units) was chosen from the requirement 2 detach AE mg = , i.e., gravity equals the electric force when the marble detaches from a substrate (the experimental value of E detach was about 24 cgse.)…”

Liquid Marbles as Micro‐bioreactors for Rapid Blood Typing

“…Due to their unique properties, liquid marbles have been the subject of a collection of studies in the past decade, centered on fundamental research on their properties, as well as their practical applications 1–37. These liquid droplets, enwrapped with solid powder while having no direct contact with the supporting substrate, may be exploited for a wide range of applications ranging from, but not limited to, the displacement of a small volume of liquid without any leak left behind,2 water surface pollution detection,13 gas detection, gas–liquid reactions,8, 30, 31 and, last but not the least, preparation of microreactors 7, 30, 31, 34.…”

Improvement of Solvent Exchange for Supercritical Dried Aerogels

“…The variation of washing periods was indicated as a strengthening method for silica aerogels by using of acidic or basic catalysts. Increased period of washing led to strengthened gels and reduced shrinkage (Einarsrud et al, 2001;Bangi et al, 2010). Robitzer et al (2008) observed shrinkage of wet calcium alginate gels even during solvent exchange, where the exchange of water by ethanol led to a 4% volume shrinkage.…”

“…The influence of the solvent type on the RF aerogel structure was studied by Lambert et al (1997), where they observed a swelling of gels during washing with isopropanol. Bangi et al (2010) investigated the effects of washing temperature and washing periods and similar to Lambert et al, they varied the washing solvents. They found out that elevated temperature crumbled the gel network leading to high shrinkage of about 70% (Bangi et al, 2010).…”
