Viscoelastic lithography for fabricating self-organizing soft micro-honeycomb structures with ultra-high aspect ratios
Tissue engineering applications call for controllable micro-structural units as a platform, but their fabrication remains challenging. Here, Jeong et al. show a method that enables soft materials to self-organize into highly packed micro-honeycomb structures with aspect ratios up to 500, and tunable shapes.

Multiplex lithography for multilevel multiscale architectures and its application to polymer electrolyte membrane fuel cell
Multiplex lithography is a technique that can be used to fabricate complex soft materials. Here, the authors develop a method to prepare multilevel multiscale structures and demonstrate its application on polymer electrolyte membrane fuel cells which display decreased membrane resistance and increased electrochemical active surface area.

Cracking-assisted photolithography for mixed-scale patterning and nanofluidic applications
Cracks in material are not always unwanted; sometimes, they can be manipulated to produce micro and nanoscale patterns. Here, Kim et al. report a cracking-assisted nanofabrication technique based on conventional photolithography process, which allows accurate control over the geometry of the nanopatterns in arbitrary shape.
