The paper shows that very low surface energies/surface tensions can be obtained with certain architectures of branched hydrocarbon chain surfactants.

It is part of the G8 grant collaboration between Dr Sagiasaka and Professors Eastoe (Bristol) and Guittard (Nice, France).

This is Julian Eastoe’s 250th publication, in his 25-year career.

Congratulations to Greg Smith, he has recently had a new paper accepted in Langmuir:

Interaction between surfactants and colloidal latexes in nonpolar solvents studied using contrast-variation small-angle neutron scattering

The paper helps understand the mechanism of charging colloids in non-aqueous media by adding ionic surfactants.

Congratulations to Masa Sagisaka, or collaborator from Hirosaki, Japan.

This week (24 May 2013) he has had a new paper accepted in Langmuir:

Congratulations to Dr Azmi Mohamed, ex-PhD student in the Bristol Surfactant Group, now Senior Lecturer in Chemistry, Universiti Pendidikan Sultan Idris, Malaysia.

Azmi has won a Gold Medal for his presentation to Malaysia Technology Expo 2013 (http://www.mte.org.my/2013/mte2013/).

The winning work was entitled ' Low cost hybrid CO2-philic surfactants for green solvents' and was based on our recent papers in Langmuir.

Here is what Azmi said about it:-

“I can't believe we won and I feel just like came back from the London Olympics!”.

Well done Azmi - you ROCK!

Here is what the Reviewers said about the paper:-

“This is a first class focused review on stimuli responsive surfactants, and I believe it will nucleate a lot of additional significant work in the responsive soft materials arena…
The paper is very well written and I could not find any errors within. I unequivocally endorse its rapid publication.”

“This is very nice idea that people publish a review paper in Soft Matter on a real cross-disciplinary domain including chemistry and physics…this paper is useful and it deserves being published as a review in Soft Matter. The body of the paper is very interesting and well-written, it gives a stimulating reading. I liked very much the parts on CO2-sensitive and magnetic surfactants.”

Soft Matter Home-Where physics meets chemistry meets biology for fundamental soft matter research. Where physics meets chemistry meets biology for fundamental soft matter research.

The UK funding agency EPSRC have recently instigated a community-wide consultation exercise for proposed Centres for Doctoral Training (CDTs).

We need your support to build momentum for an 8-year in Scattering from Soft Matter.

The working title of our proposal is “The Hard Science of Soft Matter: Training a New Generation”.

It will involve the Universities of Bath, Bristol and Cardiff, and the scattering facilities ISIS and diamond in Didcot UK, ILL and ESRF Grenoble France, as well as wide-ranging interactions with Industry.

It would be very helpful to the case for our proposal if you could take the few minutes to fill in this web form.
