Djen’s paper appeared online today on the Advanced Materials Technologies website!
A major challenge for soft electroactive devices such as dielectric elastomers is the fabrication of thin, precisely patterned, stretchable conductors. In this work, laser‐scribed graphene oxide is used to fabricate intricate, stretchable electrodes for dielectric elastomer actuators.
The method is simple, low‐cost, and green (free of organic solvents) and produces arbitrary geometries with 0.1 mm resolution.
It has been a great week for publications! Ben’s paper was recently accepted, and just appeared earlier today on the MSDE (Molecular Systems Design & Engineering) website! This study, entitled “Tipping the polaron–bipolaron balance: concentration and spin effects in doped oligo(aniline)s observed by UV-vis-NIR and TD DFT” is an invited contribution to the special themed collection “Soft Materials Nanoarchitectonics”.
We describe a robust computational protocol for modelling the molecular geometries, electronic structures and absorption spectra of oligomers of the widely-used and versatile conducting polymer, poly(aniline). By comparing experimental UV-vis-NIR and EPR spectra with TD-DFT simulations, we discovered it is possible to switch reversibly between diamagnetic and paramagnetic forms (bipolaronic and polaronic states) of oligo(aniline)s in solution simply by adjusting dopant concentrations – a finding which could reinvigorate research into conduction mechanisms in poly(aniline) and related materials, as well as allowing control of material properties and functionality.
Well done Ben, Shao, Steph, and collaborators Dave, Patrice and Natalie!
Great news – Djen’s paper on “Laser-scribed Graphene Oxide Electrodes for Soft Electroactive Devices” has been accepted for publication by Advanced Materials Technologies.
Here we (Djen, Jonathan Rossiter and Charl) show that laser-scribed graphene oxide (LSGO) can be used to fabricate patterned, stretchable electrodes for dielectric actuators (DEAs) – even an actuating University of Bristol logo!
Well done Djen!
Charl was invited, as visiting professor, to spend a few days at the University of Rennes1 by former postdoc Dr Franck Camerel. Franck, who is in the MaCSE (Matière Condensée et Systèmes Electroactifs) group,
Several days of excellent and stimulating scientific discussions were closely accompanied by good food, and the pleasure of seeing old friends again! Thank you Franck!
It was great to be able to host (with fantastic support from the BCFN) 5 staff and 10 graduate students from the State Key Laboratory for Supramolecular Structure and Materials, College of Chemistry, Jilin University (Changchun, China)! The visit, to discuss new joint undergraduate programmes, and to further explore research interactions, was a fantastic success!
There was also a poster session, where Esther and Christian presented some of their latest results! More photos to follow!
Great to see old friends again (including Prof Kun Liu and Dayang Wang), but also to make many new friends and connections!
Charl joined an international panel of experts to help with the external evaluation of the School of Chemistry and Chemical Engineering at BIT (Beijing Institute of Technology). The evaluation ended with a series of scientific seminars by some panel members, including Prof. Donglin Jiang (now at NUS, Singapore), and Charl!
Here Donglin and Charl are in discussion after Donglin’s impressive talk!
Charl finally had the chance to visit an old friend, Prof Dan Wang, at the Chinese Academy of Science’s Institute of Process Engineering. Prof Wang and his group focus on the production of functional hollow multi-shell particles for a wide range of energy applications – with some very impressive results!
After an exciting series of talks by PhD students from Prof Wang’s group, Charl gave a seminar and provided an overview of FRG research activities! Here he is being questioned by Prof Wang!
