Influence of Surface Finish on the Tribological Performance of AlTiBN Coatings Deposited on Forming Tools

Advanced Engineering Materials, EarlyView.
Aluminum and nitride coatings are used in industry because they are hard, resist wear, and protect against oxidation. Adding boron can improve friction behavior and other properties. This study tests coatings on surfaces with different finishes. Results show smoother surfaces perform better, while rough ones wear faster, although coatings can reduce ...

Crystalline Structures and Non-crystalline States of Polymers

Kobunshi, 1971
高分子とは何かを構造の面から浮き彫りにするため,低分子との比較から出発し,プラスチック,フィルム,繊維などで強さを表わす高分子の特長が,ラメラ晶,球晶間のtie-linkによる網目構造的なものに関係していることを強調した。他方,無定形ガラス状態にある高分子について,ランダムコイルか特殊な形態をとるのかという問題を提起した。次に高分子が結晶を形成する因子について説明し,結晶弾性率を解説した。結晶,非晶両領域の共存する高次構造を説明する基礎として,希薄溶液から単結晶の析出する機構を考察し,次に溶融状態からの球晶の生成とその高次構造について述べた。ラメラ晶の規則的集合からなる球晶の変形を基本的な過程に分離して説明し,最後に配向結晶化による配向物の構造の特長を指摘し, 強度を支配するtie-link ...

Exploring Dipolar Dynamics and Ionic Transport in Metal‐Organic Frameworks: Experimental and Theoretical Insights

Advanced Functional Materials, EarlyView.
In this study, the interplay of dipolar dynamics and ionic charge transport in MOF compounds is investigated. Synthesizing the novel structure CFA‐25 with integrated freely rotating dipolar groups, local and macroscopic effects, including interactions with Cs cations are explored.

In Situ Constructed Magnetic Core‐Shell Hydrogen‐Bonded Organic Framework‐on‐Metal–Organic Framework Structure: an Efficient Catalyst for Peroxymonosulfate Activation

Advanced Functional Materials, EarlyView.
In this work, a magnetic core‐shell catalyst (HOF‐on‐Fe3O4/ZIF‐67) is successfully synthesized, consisting of a metal–organic framework (ZIF‐67) with magnetic Fe3O4 as the core and a porous hydrogen‐bonded organic framework (HOF) as the shell. The catalyst efficiently activated peroxymonosulfate, resulting in rapid and effective removal of water ...

Enhancing Optoelectronic Properties in Phthalocyanine‐Based SURMOFs: Synthesis of ABAB Linkers by Avoiding Statistical Condensation with Tailored Building Blocks

Advanced Functional Materials, EarlyView.
A novel phthalocyanine (PC)‐based metal–organic framework (MOFs) is synthesized using ditopic PC linkers obtained through regioselective statistical condensation. The resulting MOF exhibits significant improvements in electronic absorption, thereby enhancing the material's performance in light harvesting and energy conversion.
