Soft Matter: looking to the future

Over recent years Soft Matter has grown, mirroring the growth of the subject, which has been fantastic for the journal. This growth has given us an excellent foundation on which to build the journal’s future.

The ultimate aim of the journal is that, as authors, your research published in Soft Matter will be highly visible to those you want to read it and, as readers, you will easily be able to find the articles you are most interested in and discover the latest breakthroughs in our field. In a recent Editorial the Editorial Board have discussed how Soft Matter will be developing to ensure the journal continues to meet this aim.

Flat-pack structures build themselves

Scientists in the US have developed flat pack structures that can autonomously assemble into three-dimensional shapes on application of an electrical current. Unlike traditional three-dimensional assembly techniques, which require sophisticated printers to reach the final product, this approach uses heat triggered shape memory polymers.

Three-dimensional structures normally come pre-assembled or equipment needs to be transported to create them in situ. Now, along with his colleagues, Samuel Felton, from Harvard University, has demonstrated that by printing shape memory polymers (SMP) onto laser-cut joints with conductive coatings, the assembly process can be separated entirely from the original printing.

Initiation of the SMP transformation is central to Felton’s technique. A SMP is printed in a deformed, flat state and aligned with a resistive circuit over a scored substrate, in this case, paper. An electric current is then run through the circuit and joule heating activates the phase transformation of the shape memory polymer back into its original shape and folds the paper. As this combination is electrically triggered, it allows both simultaneous and sequential folding of complicated shapes.

Felton explains that the most challenging aspect of the work was creating the precisely aligned composite as the approach relies upon separately cut layers that are then joined using a mixture of pins and silicone tape. As alignment is performed when manufacturing the flat structure, the end product is, as was the aim, ‘accessible for everyone.’

Jinsong Leng, an expert in smart materials at Harbin Institute of Technology, China, agrees: ‘shape memory composites play an enormous role in self-folding structures formed by remote and automated assembly. The approach could significantly accelerate the advancement of promising applications in 3D structure fabrication techniques.’

Julia Yeomans elected to FRS

It was with great pleasure that we learnt that regular Soft Matter author Professor Julia Yeomans has recently been elected to the Fellowship of the Royal Society.

Professor Yeomans is a theoretical and computational physicist working on statistical physics, hydrodynamics, soft condensed matter and biological physics. Among her current research interests are microswimmers, active systems, liquid crystals and drop dynamics. She holds an ERC Advanced Grant ‘Microflow in Complex Environments’.

Julia obtained her MA in Physics and DPhil in Theoretical Physics from the University of Oxford. She spent two years as a post doc at Cornell University, USA, in the group of Michael Fisher and then returned to the UK, to a Lectureship at the University of Southampton. Shortly thereafter she joined the Rudolf Peierls Centre for Theoretical Physics at Oxford. She is currently Professor of Physics at Oxford, a member of the Oxford Centre for Soft and Biological Matter, and Pauline Chan Fellow, St Hilda’s College.

Earlier this year, Julia was also awarded the EPJE Pierre Gilles De Gennes Lecture Prize, for her contribution to the study of the dynamical behaviour of complex and active liquids in confined geometries. She said of winning the prize: ‘I am delighted by this award. It is recognition for the wonderful students, post-docs and colleagues from all over the world that I have had the privilege and pleasure of working with.’

Recent Soft Matter publications by Julia Yeomans include:

Modelling unidirectional liquid spreading on slanted microposts
Andrea Cavalli, Matthew L. Blow and Julia M. Yeomans
Soft Matter, 2013, Advance Article

Length-dependent translocation of polymers through nanochannels
