Microfluidic devices can be used to produce highly controlled and monodisperse double or multiple emulsions. The presence of inner drops inside a jet of the middle phase introduces deformations in the jet, which leads to breakup into monodisperse double emulsions. However, the ability to generate double emulsions can be compromised when the interfacial tension between the middle and outer phase...

Big data, the mobile Internet, social media and the Internet of things (IOT) generate more information than ever but the aggregation of social intelligence remains far from realising it’s potential. Two exemplary works, mediated_moments and plasma_flow, exhibited at Beijing’s China Millennium Monument Museum of Digital Arts in 2012 model the scalable potential of urban media to weave itself int...

This is a study of elastic waves diffracted by corrugated metallic surfaces. The corrugations consist of triangular grooves with variable parameters. The results of the narrow band experiments show significant diffraction patterns depending on angle and frequency. In addition, a continuous schlieren system is used to visualize the diffracted orders. Measurements were also carried out using a br...
