THE WORLD’S LONGEST EVER BOTTLEBRUSH POLYMER SYNTHESIZED

NIMS and RIKEN have succeeded in synthesizing the longest ever bottlebrush polymer. Resembling a green foxtail, this polymer is composed of a main chain and numerous side chains grafting from it. EurekAlert!, the website run by the American Association for the Advancement of Science, gave us the good news
 

THE LONGEST BOTTLEBRUSH POLYMER

This research team has recently succeeded in synthesizing the longest bottlebrush polymer ever by devising the molecular design of the monomer as starting material and using a single crystal of the monomer to set up a polymerization environment with very few impurities. The length reached 7 μm, which is about 3.8 times longer than the longest value so far. Furthermore, by combining two types of polymerization methods, the research team succeeded in synthesizing bottlebrush polymers with four types of side chains while maintaining the length of the main chain.

 

MANY JAPANESE RESEARCHERS COLLABORATE ON PROJECT

This project was carried out by a research team led by Yoshihiro Yamauchi (Independent Scientist, Research Center for Functional Materials, NIMS) and Yasuhiro Ishida (Team Leader, Center for Emergent Matter Science, RIKEN). This work was mainly supported by the JSPS Grant-in-Aid for Scientific Research, the JST Strategic Basic Research Program CREST, the Izumi Science and Technology Foundation, the Iketani Science and Technology Foundation, and the Shorai Foundation for Science and Technology.

IL FUTURO DEL B2B È DIGITALE. E STA ARRIVANDO PIÙ VELOCEMENTE DI QUANTO PENSIAMO

Secondo l'Osservatorio B2B Digital Commerce del Politecnico di Milano, nel 2024 il valore degli ordini B2B gestiti in digitale in Italia ha raggiunto 278 miliardi di euro, con una crescita del +5% in un solo anno. Eppure, il digitale rappresenta ancora solo il 22% delle transazioni B2B: un segnale chiaro di quanto spazio di evoluzione ci sia ancora, un'enorme opportunità ancora da cogliere. Le imprese che oggi costruiscono ecosistemi digitali, connessi e orientati alla relazione con il cliente ...
