Unexpected stability of aqueous dispersions of raspberry-like colloids
Nature Communications, 2018 The ability to stabilise colloidal suspensions in solution against salt-induced aggregation is critical to many industrial applications, but it remains challenging at high salt concentration. To overcome this problem, Lan et al.

Advanced Engineering Materials, EarlyView.The share of technical thermoplastics is expected to grow further in the e‐mobility segment. In this study, a detailed temperature‐based tribological characterization of technical thermoplastics is performed. The tribological properties are discussed in terms of the dynamic mechanical properties of polymers at different ambient temperatures. A proof of

Kobunshi, 1968 ポリエチレンやポリプロピレン,一般にプラスチックが広大な需要をもつようになるとともに,染色,印刷,接着などの二次加工における困難や,静電気に基く障害などが工業的に重大な問題になってきた。これらはいずれも主として界面化学的な問題で,基本的には高分子物質の表面自由エネルギー(表面張力)の知識をもとにして解決の道を探し出すことができる。一方表面張力は液体の分子間相互作用を表わす熱力学的な物理量の一つで,凝集エネルギー密度を実測することのできない高分子では特別な重要性をもっている。さらにそのなかで高分子性(分子がつながっているという効果)を調べるなら,これは学問的にも興味がある。幸い多くの鎖状高分子は溶融することができるので,その表面張力の分子量依存性,分子構造との関係 ...
