Bristol Surfactant Research - Professor Julian Eastoe

Congratulations to Shirin Alexander, she has recently had a new paper accepted in Langmuir:

Low Surface Energy Surfactants with Branched Hydrocarbon Architectures

Shirin Alexander,Gregory Smith, Craig James, Sarah Rogers, Frederic Guittard, Masanobu Sagisaka, Julian Eastoe*, Langmuir, 2014, la-2014-00332s.R1 accepted 11-Mar-2014

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

Gregory Smith, Shirin Alexander, Paul Brown, David Gillespie, Isabelle Grillo, Richard K Heenan,. Craig James, Roger Kemp, Sarah Rogers, Julian Eastoe*, Langmuir, 2014, a-2014-00331u.R1 accepted 05-Mar-2014

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:

Nanostructures in Water-in-CO2 Microemulsions Stabilized by Double-chain Fluorocarbon Solubilizers

Masanobu Sagisaka*, Shuho Iwama, Shinji Ono, Atsushi Yoshizawa, Azmi Mohamed, Stephen Cummings, Ci Yan, Craig James, Sarah Rogers, Richard K Heenan, Julian Eastoe

Langmuir, 2013, accepted 23-May-2013 la-2013-00376g.R1

The paper reports on new surfactants, which give droplet microemulsions or lamellar phase dispersions in liquid CO2. It is part of the G8 grant collaboration between Dr Sagiasaka and Professors Eastoe (Bristol) and Guittard (Nice, France).

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!

Congratulations to Paul Brown, ex PhD student in the Bristol surfactants group, now Post-doc at MIT with Prof T. Alan Hatton: his new paper has just been accepted in Chemical Communications.

It is a collaboration with our Brazilian colleagues, including Rodrigo J de Oliveira who was a visiting student in Julian’s lab in 2011, and we are proud to have this joint publication with them.

Paul Brown, Craig Butts*, Julian Eastoe*, Eduardo Padrón Hernández, Fernando Luis de Araujo Machado and Rodrigo J de Oliveira, Chem Comm, 2013, DOI:10.1039/C3CC00103B

Here is what one of the Reviewers said about the paper:-

“This is an important paper that reports new findings eventually employed in a wide range of technologies processes and products. I do not have criticisms since the paper is well written and deals with important results.”

Congratulations to Paul Brown, ex PhD student in the Bristol surfactants group, now Post-doc at MIT with Prof T. Alan Hatton: his new paper has just been accepted in Langmuir.

Properties of New Magnetic Surfactants
Paul Brown, Alexey Bushmelev, Craig Butts, Jean-Charles Eloi, Isabelle Grillo, Peter Baker, Annette Schmidt, Julian Eastoe*, Langmuir, 29, 2013, accepted 15-Feb-2013 la-2013-00113r.R2

Here is what the Reviewers said about the paper:-

“This is an excellent paper describing some new magnetic surfactants. In addition to the interfacial effects and applications described, we can expect this work to have broad application in surfactant and polymer chemistry. I commend it for publication.”

“The subject is also of significant interest and fits in the scope of this Journal.”

Congratulations to Greg Smith PhD student in the Bristol surfactants group: his new paper has just been accepted in Langmuir.

Evidence for a critical micelle concentration of surfactants in hydrocarbon solvents
Gregory Smith, Paul Brown, Sarah Rogers, Julian Eastoe*, Langmuir, 2013, 29, accepted 15-Feb-2013, la-2013-00117s.R115-Feb-2013.

Here is what the Reviewers said about the paper:-

“These results and discussion seem important for this science field.”

“I am convinced that in the studied systems, the so-called CMC does exist.”
