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.

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.

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.

The Mechanical Forces in Biology symposium, which takes place at EMBL Heidelberg from 12-15 July, aims to unite the field of mechanobiology, by bringing together world-leading experts in the generation and sensing of forces from the molecular scale to the organismal scale, with an important emphasis on the combination of physics and computer modelling with molecular genetics and live-imaging in vitro or in vivo.
The field is currently expanding rapidly and the event aims to provide a comprehensive overview of this progress as well as aiming to capitalise on the opportunities for new collaborations. Topics covered in the symposium include: force generation; mechanosensing; mechanotransduction; cellular morphogenesis and tissue morphogenesis.

Conducting composite senses damage and stiffens on impact
Chinese scientists have used conducting carbon nanotubes and impact-responsive polymers to create a smart Kevlar composite with enhanced ballistic and stab resistance. Body armour made from this material could sense the force and location of impacts, and detect when it has been pierced.
Flexible, lightweight and durable, Kevlar has been a key component in personal armour for decades. It has excellent stab and cut resistance, making it the primary component in police stab vests, also offering limited protection against small arms fire.

Scanning electron microscopy images showing regular Kevlar (a, b) and the improved version with different shear-stiffening polymer/Kevlar ratios (c: 4.8 weight% polymer; f: 84 weight% polymer)
The problem with Kevlar’s flexibility is that when it stops a bullet, the energy is still transferred directly to the wearer at the point of impact, which causes trauma – imagine being punched at the speed of a bullet! For military applications, where Kevlar would not stand up to high-velocity rifle rounds, it is often combined with heavier steel or ceramic plates to spread the impact over a larger area.
