Silicon dioxide hollow microspheres with porous composite structure: Synthesis and characterization

Hybridization of helical poly(phenylacetylene)s bearing l-proline tripeptide pendants into porous silica microspheres as a solvent-tolerable chiral stationary phase for liquid chromatography

“…Firstly, the SiO 2 seeds and SiO 2 PMS solutions were prepared according to the reported approach (ESI Section 3 †). 32,33 The SiO 2 PMS solution (100 mL) was then mixed with ethanol (20 mL), NH 3 •H 2 O (20 mL), distilled water (160 mL), and CPA (0.10 g). After stirring for 16 h at 35 °C and standing for 24 h, the HCSP was thoroughly cleaned with H 2 O and ethanol, and then dried for 18 h at 30 °C in vacuo.…”

Interaksi Molekuler Amonium Hidroksida

“…Termokimia ialah sinonim dari termodinamika kimia. Termokimia larutan NH4OH dibagi menjadi dua, yaitu entropi molar standar dan entalpi molar standar (66,67) . Entropi molar standar atau yang biasa disimbolkan dengan S 0 merupakan entropi satu mol suatu senyawa pada keadaan standar (bukan dalam STP).…”

Demonstration of π–π Stacking at Interfaces: Synthesis of an Indole-Modified Monodisperse Silica Microsphere SiO2@IN

“…Silica microspheres represent prototypical inorganic nanomaterials distinguished by outstanding stability, chemical inertness, and nontoxicity, endowing them with significant theoretical research implications and broad market application potential. − The integration of π–π stacking interactions onto the surface of silica microspheres to fabricate novel, modified materials presents a promising avenue, leveraging synergistic performance advantages and thus constituting a pivotal research focus. − Furthermore, the meticulous screening of experimental conditions and optimization of the preparation process are paramount in shaping the performance characteristics of such materials.…”
