Typical diffusion behaviour in packaging polymers - Application to functional barriers

, 2006
When plastics are collected for recycling, possibly contaminated articles might be recycled into food packaging, and thus the contaminants might subsequently migrate into the food.

Sub‐Diffraction Nanolithography of Halide Perovskite via Reversible All‐Optical Crystallization–Decomposition

Advanced Materials, EarlyView.
A reversible, all‐optical modulation strategy enables resist‐free, sub‐diffraction nanolithography of halide perovskite films. Leveraging 800 nm fs laser‐induced crystallization and 365 nm laser driven decomposition, reconfigurable patterning achieves feature sizes down to 93.5 nm. This chemistry‐free approach offers dynamic control over optoelectronic

Micropillar‐Engineered Hybrid Adhesive Patch for Surface‐Conformable and Directional Adhesion

Advanced Materials Technologies, EarlyView.
This work presents a surface‐conformable hybrid adhesive integrating height‐optimized hexagonal micropillars with open‐rectangular cuts. The micropillars enhance rough‐surface contact and microscale crack arrest, while the cuts guide and reverse interfacial cracks for strong and directional adhesion. The multiscale architecture achieves robust pull‐off

Crystallization of Polyethylene Terephthalate

Kobunshi Kagaku, 1969
等温結晶化したポリエチレンテレフタレートの球晶構造を小角光散乱, 光学顕微鏡および密度測定により検討した。試料には結晶化温度および時間を変えたものを用いた。結晶化温度110℃から140℃までの領域では通常の光散乱理論により説明される散乱像を得たが, 140℃以上の領域では四つ葉のクローバー像で代表される典型的な球晶による散乱の他に散漫な散乱や, あるいは新しい散乱像も見られた。結晶化条件, 配向度あるいは分子量およびジエチレングリコール含有率といったポリマー特性によっても散乱像は影響を受けるがポリエチレンテレフタレート球晶の構造は, その散乱像から理解できる。
