Have you read Soft Matter Issue 22? The issue is themed on the Physics of Buckling with Alfred Crosby (University of Massachusetts, Amherst, USA) as the guest editor.
Why should we care about buckling? Alfred Crosby explains in his editorial. You can read the editorial for free, although you may need to register.
The paper featured on the front cover is High aspect ratio wrinkles on a soft polymer by Sk. Faruque Ahmed, Geon-Ho Rho, Kwang-Ryeol Lee, Ashkan Vaziri and Myoung-Woon Moon. The paper presents a method to pattern polymer surfaces with wrinkles with an amplitude/wavelength ratio as large as 2.5. A novel application of high aspect ratio wrinkles in optics is demonstrated.
