Elucidation of interactive effects of synthesis conditions on the characteristics of mesoporous silicas templated using polyoxide surfactant

Science and Technology of Advanced Materials, 2007
A series of mesoporous silicas (MS-1–MS-9) were synthesized at different gel compositions using a triblock copolymer (TCP), poly(ethylene oxide)–poly(propylene oxide)–poly(ethylene oxide), as the surfactant.

Isothermal crystallization of poly(ethylene oxide) in poly(ethylene oxide)/poly(methyl methacrylate) blend systems.

KOBUNSHI RONBUNSHU, 1990
ポリエチレンオキシド (PEO) /ポリメタクリル酸メチル (PMMA) ブレンド中でのPEOの等温結晶化過程に及ぼすPMMAのタクチシチーならびに分子量の影響を検討した. 結晶化速度はPMMAの組成と分子量の増加に伴い遅くなる. ブレンド試料の融解熱はPMMA分子量には依存せず, PMMA組成が増加すると小さくなる. また, 融解熱はPMMAタクチシチーに依存しアイソタクチック, シンジオタクチック, アタクチックの順に小さくなる. 結晶化の活性化エネルギーはPMMA組成と分子量には依存せず, PMMAタクチシチーに依存し, アイソタクチック, シンジオタクチック, アタクチックの順に小さくなる.

Oxidation of tertiary amine-derivatized surfaces to control protein adhesion [PDF]

, 2013
Selective oxidation of omega-tertiary amine self-assembled thiol monolayers to tertiary amine N-oxides is shown to transform the adhesion of model proteins lysozyme and fibrinogen upon them.

Solution‐Processed Two‐Dimensional Indium Oxide on Sodium‐Embedded Alumina for Reconfigurable Optoelectronic Synaptic Transistors

Advanced Functional Materials, EarlyView.
Wafer‐scale two‐dimensioanl In2Se3 oxidized into InOx on sodium‐embedded beta‐alumina enables multifunctional reconfigurable electronics. Sodium ions accumulate within distinct spatial distribution under drain‐controlle and gate‐controlled operation. Drain‐control operation gives controllability of ultraviolet‐driven optoelectronic synaptic conductance

Aqueous Two‐Phase Bioinks for Discrete Packing and Compartmentalization of 3D Bioprinted Cells

Advanced Healthcare Materials, EarlyView.
Aqueous two‐phase systems (ATPS) enable the formation of biomimetic interfaces crucial for tissue engineering. However, clinical translation remains limited by the challenge of precisely controlling cellular compartmentalization. Here, we developed ATPS biomaterial inks for 3D bioprinting allowing tuneable droplet formation via NaCl modulation.

Molecular weight fractionation by confinement of polymer in one-dimensional pillar[5]arene channels

Nature Communications, 2019
Confinement of polymers in nano-spaces can induce unique molecular dynamics and properties. Here the authors show high mass fractionation by the confinement of single polymer chains of poly(ethylene oxide) in the one-dimensional channels of crystalline ...

Fluorescent Nanosensor for Indole‐3‐Propionic Acid Detection in Gut Health Monitoring

Advanced Healthcare Materials, EarlyView.
This work introduces a fluorescent nanosensor system with two optical modalities for detection of indole‐3‐propionic acid (IPA) gut metabolite: (1) blue‐emitting cationic conjugated polyelectrolyte (CP3) and (2) near‐infrared (NIR)‐emitting CP3‐wrapped single‐walled carbon nanotube (SWNT).

The Floor‐Ceiling‐Chip, or 2 × 2D = Pseudo‐3D—Approaching 3D Cell Morphology and Organization between Two Opposing 2D Substrates with Cell‐Adhesive Protein Micropatterns

Advanced Healthcare Materials, EarlyView.
Here, we present a novel 3D cell patterning and culture platform. The “Floor‐Ceiling‐Chip” (FC‐Chip) consists of two opposing track‐etched membranes, creating a pseudo‐3D microenvironment for the cells in between. By providing the membranes with micropatterned cell‐adhesive islands of varying geometries and sizes, the FC‐Chip enables control over cell ...
