Functionalization of Carbon and Silica Gel by Phosphoric Acid

Adsorption Science & Technology, 2007
Functionalization of polymer-based carbon (SCS-3) and silica gel (SG60) by phosphoric acid at 800°C was investigated. It was shown that heat treatment of carbon and silica gel in the presence of phosphoric acid at 800°C provides a way of functionalizing ...

Biomimetic Iridescent Skin: Robust Prototissues Spontaneously Assembled from Photonic Protocells

Advanced Functional Materials, EarlyView.
Uniform nanoparticles are induced to form arrays (photonic crystals) in the cores of biopolymer capsules, endowing these ‘protocells’ with structural color. These protocells are then assembled into large self‐standing objects, i.e., prototissues, with robust mechanical properties as well as iridescent optical properties.

Covalent Organic Frameworks for Water Sorption: The Importance of Framework Physical Stability

Advanced Functional Materials, EarlyView.
This study explores the water‐vapor stability of 2D covalent organic frameworks (COFs) with varying pore sizes. Results reveal microporous COFs demonstrate superior stability compared to mesoporous ones, despite lower water uptake. Mesoporous keto‐enamine‐linked COFs show enhanced stability due to intralayer hydrogen bonds, confirmed by simulations and

Light‐Responsive Enzyme‐Loaded Nanoparticles for Tunable Adhesion and Mechanical Wound Contraction

Advanced Functional Materials, EarlyView.
This study presents a photoactivatable enzyme‐loaded mesoporous nanoparticle system (MPDA_PaTy) that enables light‐triggered tunable tissue adhesion and facilitates mechanical wound contraction. Controlled enzymatic crosslinking at tissue or hydrogel interfaces allows on‐demand adhesion.

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.

Tailoring the Properties of Functional Materials With N‐Oxides

Advanced Functional Materials, EarlyView.
The properties of materials bearing N‐oxide groups are often dominated by the polar N+─O− bond. It provides hydrophilicity, selective ion‐binding, electric conductivity, or antifouling properties. Many of the underlying mechanisms have only recently been discovered, and the interest in N‐oxide materials is rapidly growing.

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 ...
