Engineering Photonic Pigments From Titania–Block Copolymer Composites
Ligand‐functionalized TiO2 nanoparticles selectively partition into P2VP‐rich lamellae of onion‐like PS‐b‐P2VP microspheres, increasing refractive index contrast while preserving concentric order through controlled self‐assembly. The resulting dry photonic pigments display defined Bragg reflections and angle‐robust structural color.

Liquids at silica interfaces experience demixing as a consequence of their respective polarity. The distribution of liquids and their primary relaxation contributions are studied by surface modification with OD and radical moieties, respectively. ABSTRACT NMR relaxation of liquids in the presence of solid interfaces, such as silica gel or porous glass,

Lifetime assessment of high-density polyethylene–silica nanocomposites
In this work, the effect of fumed silica on the long-term resistance of high-density polyethylene was investigated. Different amounts of functionalized fumed silica nanoparticles were dispersed in a high-density polyethylene matrix by melt compounding ...

コンクリートにシリカフュームを用いることにより, コンクリートの高強度化などの効果が期待されている. しかしながら, シリカフュームそのものの品質特性や, コンクリートの諸特性に影響を及ぼすシリカフュームの品質についても未だに不明確であり, シリカフュームに関する規格, 基準も整備されていないのが現状である. このような背景から, 本研究ではまず, 我が国で入手可能な13銘柄のシリカフュームを対象とし, その品質特性を明らかにし, 次にコンクリートの諸特性に影響を及ぼすシリカフュームの品質指標を明らかにすることを試み, これを通じてシリカフュームの品質とその評価に関する提案を行ったものである.
