Djen’s paper published online!

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.

 

And now Ben’s paper – accepted and published online!

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!

Djen’s paper accepted!

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!

Another joint Manners/Faul paper!

Charlie, who was a joint Manners/Faul student (and now in Toronto), just had a full paper accepted in Chemistry European Journal! He had helped from Henry, from the Faul group, Xiaoming, former Manners group postdoc and Rob from the EM unit.

In this paper we show controlled solution self-assembly of an amphiphilic perylene diimide by a seeded-growth mechanism, to form colloidally stable, one-dimensional fibres with controllable lengths and low dispersities under kinetic control. Well done to all involved!

 

 

Invited Focus Review on electroactive amphiphiles accepted!

We just heard that your invited Focus Review for ChemNanoMat (part of a Special Issue on Supramolecular Nanostructures) has been accepted! In this Focus Review, which has already appeared online, we aim to highlight an exciting class of materials, electroactive amphiphiles (EAAs).

Well done to Esther, Maha, Kazu, Ben and close collaborator Annela Seddon (also Esther’s joint PhD supervisor)!  And special thanks to Kazu for the great frontispiece and graphics!

Visiting PKU!

Charl visited the College of Chemistry and Molecular Engineering at Peking University in Beijing today. He visited old friends Prof Qi Limin, who also spent time at the Max Planck Institute of Colloids and Interfaces in Golm, and Prof Yun Yan, who was part of the same ESF scientific network.

After Charl’s talk there were some very interesting discussion with prof Huang Jianbin concerning the FRG’s recent paper in Chemical Science!
