Synthesis of Organofunctionalized Silica Gel from Organostannio Silica Gel and Alkoxysilane.

NIPPON KAGAKU KAISHI, 1997
Organofunctionalized silica gel was readily prepared from the organostannio silica gel, which had dib utyl or tributylstannio group, and (3-methacryloxypropyl) trimethoxysilane. The reaction in the presence of acid or base catalyst proceeded with the elimination of organotin group to produce the silica gel having a high content of the organofunctional ...

Preferential Interfacial Engineering of Hydrogels via Interdigitated Nanoparticle Assembly

Advanced Functional Materials, EarlyView.
Robust surface functionalization of hydrogel surfaces is performed via interdigitated metal nanoparticle assembly, inducing strong affinity with the hydrogel matrix. The partially exposed nanoparticle domains act as interfacial nanobridges that mediate both chemical and physical bonding with diverse materials, including small molecules, fluorous ...

Conditions for Shake-Gel Formation: The Relationship between the Size of Poly(Ethylene Oxide) and the Distance between Silica Particles

Molecules, 2022
Colloidal silica suspensions are widely used in many fields, including environmental restoration, oil drilling, and food and medical industries. To control the rheological property of suspensions, poly(ethylene oxide) (PEO) polymers are often used. Under

Synthesis of Organofunctionalized Silica Gel from Organostannylated Silica Gel and Chlorosilane

Journal of the Ceramic Society of Japan, 1998
Tri- and dibutylstannylated silica gels were prepared from water glass and tri- and dibutyltinoxide, respectively. Organofunctionalized silica gels were readily formed via reaction between the tri- and dibutylstannylated silica gels and acetoxyethyldimethylchlorosilane or acetoxyethylmethyl-dichlorosilane with the elimination of organotin groups.

Development of evanescent wave pH sensors based on coated optical fibres [PDF]

, 1996
The development of fibre optic ammonia and pH sensors using analyte-sensitive reagents entrapped in a sol-gel-derived silica film is presented. These sensors are based on evanescent wave absorption using unclad fibres dipcoated with the chemically ...

Biodegradable 3D‐Printable and Coatable Antifouling Composites for Marine Applications

Advanced Functional Materials, EarlyView.
Marine biofouling damages submerged surfaces and raises greenhouse gas emissions. Biodegradable antifouling biocomposites were developed by hot‐mixing beeswax, Tween 80, and calcium stearate or stearic acid. Adjusting the component ratio enables processing via hot‐pressing, 3D‐printing, or dip‐coating.

Effect of Wood Fiber on the Strength of Calcareous Sand Rapidly Seeped by Colloidal Silica [PDF]

MATEC Web of Conferences, 2019
Silica nano-particles are suspended in the colloidal silica and can be induced to gradually gel after the PH value changes. Thus colloidal silica can be utilized to rapidly seep through loose calcareous sand, and the silicon gel is gradually formed to ...
