2017 Soft Matter Lectureship awarded to Daeyeon Lee

It is with great pleasure that we announce Prof. Daeyeon Lee (University of Pennsylvania, USA) as the recipient of the 2017 Soft Matter Lectureship.

The Soft Matter Lectureship is an annual award that honours an early-career researcher for their significant contribution to the soft matter field. The recipient is selected by the Soft Matter Editorial Board from a list of candidates nominated by the community.

Read on to find out more about Daeyeon…

Professor Daeyeon Lee

Daeyeon Lee obtained his PhD in Chemical Engineering at the Massachusetts Institute of Technology (MIT) in 2007 after completing a Bachelor’s Degree at Seoul National University in 2001. He then moved to Harvard University for a postdoctoral fellowship, before becoming a Professor of Chemical and Biomolecular Engineering at the University of Pennsylvania in 2009.

His current research interests focus on developing a deep understanding of the interactions between soft materials (e.g., polymers, colloids and biologicals, etc.) near or at interfaces. The major research efforts of his group include understanding the behaviour of Janus particles at fluid interfaces, improving the assembly and mechanical properties of nanoparticle films, generating hierarchical structures using emulsions and bubbles as templates, and developing catalytic systems for biomass conversion.

Since 2005, Prof. Lee has received 14 honours and awards and published 117 peer-reviewed articles. He received the Gold Award in Materials Research Society (MRS) in 2006, the AIChE NSEF Young Investigator Award in 2013, and the S. Reid Warren, Jr. Award in 2017, in recognition of outstanding service in stimulating and guiding the intellectual and professional development of undergraduate students.

To learn more about Daeyeon’s research, have a look at his recent publications in Soft Matter:

European Colloid and Interface Society Conference 2017

 

The 31st conference of The European Colloid and Interface Society will be held from 3-8 September 2017 at the Complutense University of Madrid. The annual ECIS conference is a major event for the colloid science community, whose primary goal is to bring together all major disciplines of colloids and interfaces, enabling participants to exchange knowledge, communicate with each other the results of their recent research, and to network with colleagues for new collaborations.

The ECIS 2017 will cover fundamental and applied advances in the fields of interfaces, dispersed systems, wetting, complex fluids, micro-and nano-engineered materials, upconversion nanoparticles, ion specific effects, self-assembly of surfactants, polymers and proteins, and advances in theory and instrumentation.

Plenary lectures will be given by the laureates of the Overbeek 2017 and Solvay 2017 prizes and awards will be given for the best oral presentations and poster presentations, some of which will be supported by Soft Matter.

Plenary speakers confirmed:

Abstract submission deadline for poster presentations is 30 May – click here to enter now and find out further information on the ECIS website.

Deft defecators done in 12 seconds

Fluid dynamics explain how amount and viscosity of faecal mucus makes it easy to poo

From a 4kg cat to a 4000kg elephant, any animal takes only around 12 seconds to ‘do their business’. This is what a team of US scientists found after thoroughly studying the process of defecation in over 40 animal species. They then developed a theoretical fluid dynamics model that shows how viscosity changes in faecal mucus ease excretion.

The relationship between body mass and defecation time


Despite being extensively studied from a clinical and medical perspective, the physics of pooing has until now escaped extensive exploration.

Inspired by a slow motion video of a defecating elephant obtained during their previous work on urination, David Hu and his team from Georgia Institute of Technology acquired similar videos of other mammals ranging from dogs to giant pandas. They found that despite obvious differences in animals’ size and diet, defecation time averaged to around 12 (±7) seconds across all of the species they looked at.

Tiny bubbles made easier

Shrinking the microbubbles needed for ultrasound with microfluidics

Researchers in Canada have shrunk bubbles to single-micrometre diameters, suitable for use in ultrasound.

Source: Royal Society of Chemistry
Bubbles shrink down to 1–7µm in diameter as they flow through the device’s serpentine microchannel

Microbubbles are commonly used in ultrasound imaging as they improve the visual distinction between blood and surrounding tissues. Bubbles are injected intravenously, and under ultrasound they are excited at their resonant frequency. This resonance means they scatter a much higher proportion of the ultrasound than the surrounding tissues, allowing clear imaging of blood vessels.

The bubbles needed for ultrasound are around 2µm in diameter. Current microfluidic techniques cannot produce bubbles this small, and the techniques used to generate these microbubbles generally use physical agitation or shearing. The bubbles produced often have a large size distribution, and filtration is needed to separate out those suitable for use.
