Soft interfacial materials: from fundamentals to formulation

Cover image - Courtesy of N. J. Brooks.

Royal Society Publishing has recently published a special issue of Philosophical Transactions A entitled Soft interfacial materials: from fundamentals to formulation.

The collection was organised and edited by Michael Cates, John Seddon, Nicholas Brooks, Paul Clegg and Alex Lips. who wrote an Introduction piece.

This themed issue reports papers presented at a Discussion Meeting intended not only to address the fundamental science, focusing on generic design principles for self-organisation and interfacial structure, but also to explore the resulting prospects for ‘informed formulation’ of new and improved industrial products.


This issue is available to read online, including the Introduction which is free to access:

Elastic Properties of the Brain

Young's modulus of the pituitary gland measured with AFM

Large variations in stiffness of the pituitary gland

The composition of the human body varies widely in rigidity from soft organs and fat to stiff bones.  The rigidity and stiffness of the body plays vital roles in cell behavior and tumor development, so measuring and understanding tissue stiffness is important for the design of biomaterials and cancer treatment.

In a recent Soft Matter article, a multidisciplinary group from Grenoble, France, has probed the elastic modulus of the brain, specifically the pituitary gland, which produces and regulates hormones. Unlike previous attempts, which have observed tissues at the macro scale (mm, cm), the research team has investigated the brain at the micron level.

At this subcellular scale, it was revealed that the tissue was not uniform in elasticity and there were vast differences in stiffness throughout the gland. Using atomic force microscopy (AFM), rigidity measurements from 1 kPa to 50 kPa were recorded with localized islands of increased stiffness observed.

This has been the first attempt to measure elasticity of the pituitary gland at the micron scale, providing research that could help understand cellular organization and the mechanism of tumor growth in the brain.

2nd International Conference on Soft Materials

After the great success of ICSM 2014, we are pleased to announce the second edition of the International Conference on Soft Materials (ICSM 2016).

On behalf of the organising committee, we would like to invite scientists, academicians, young researchers and students from all over the world to attend the ICSM 2016 in Pink City Jaipur.

This conference will bring together, once again, a multi-disciplinary and international group of scientists to promote and enhance recent achievements in the field of soft materials. The exchange of knowledge and discussions amongst participants will be favoured during the conference and related social events.

Interested participants might extend their stay over weekend and see Jaipur and historical monuments in nearby cities like Taj Mahal (Agra), Pushkar (Ajmer) and Red Fort (New Delhi).


Mark these dates in your diary:
15 August 2016 – Abstract deadline
31 August 2016 – Notification of accepted abstracts
30 September 2016 – Early bird registration closes
31 October 2016 – Online registration closes
12-16 December 2016 – Conference is held in Jaipur, India
