TL;DR: In this paper, a simple surface modification with octenyl succinic anhydride (OSA; food-grade) can remarkably improve the emulsification performance of CNCs, and facilitate the fabrication of the Pickering high-internal-phase emulsions (HIPEs).

TL;DR: In this article, a modified ambient drying process for synthesizing silica aerogels cost-effectively from waterglass has been developed, and the porosities, densities, and specific surface areas of the aerogel were in the range of 93-94%, 0.12-15 g/cm3, and ∼630 m2/g, respectively.
Abstract: A new modified ambient drying process for synthesizing silica aerogels cost-effectively from waterglass has been developed. Crack-free silica aerogels were obtained via solvent exchange/surface modification of wet gels using IPA/TMCS/n-Hexane solution. Silica aerogels were heated at different temperatures. The effects of heating temperature on chemical bonding state of aerogels were investigated by means of DTA and FTIR. The surface characteristic of the aerogel was hydrophobic when heat-treated under 350°C. The porosities, densities, and specific surface areas of the silica aerogels were in the range of 93–94%, 0.12–0.15 g/cm3, and ∼630 m2/g, respectively. Distinct spring back phenomena were observed in surface modified wet gels during drying.

TL;DR: The best adsorption performance observed with phenyl-grafted KIT-6 is probably related to the highest degree of surface functionalization, arising from the relatively large mesopores and bi-continuous cubic pore structure which allow great accessibility for the functional groups.

TL;DR: In this paper, two types of the charge injection mechanisms may be distinguished, in the first, charge is transferred from the excited state of the sensitizer molecule to the conduction or valence band while the second mechanism involves a direct molecule-to-band charge transfer (MBCT).

TL;DR: Alkaline hydrolysis of poly (e-caprolactone) (PCL) nanofibrous scaffolds was carried out for different time periods (1 h, 4 h and 12 h) to increase the hydrophilicity of the scaffolds to promote the proliferation and neurite outgrowth of NPCs compared to PCL and hydrolyzed PCL nanofiberous scaffolds, providing suitable substrates for nerve tissue engineering.
