Diversity of structure, morphology and wetting of plant surfaces
Kerstin Koch, Bharat Bhushan and Wilhelm Barthlott,
Soft Matter, 2008, 4, 1943
DOI: 10.1039/b804854a
A large diversity of micro- and nanostructures leads to functional plant surfaces. Here the structural diversity and wetting behavior of plant surfaces, ranging from superhydrophilic to superhydrophobic, are reviewed.

Soft Matter, 2008, 4, 1995
DOI: 10.1039/b807791f
Water gelation by the modified 2
-deoxyadenosine was observed only in the presence of ultrasound, and its self-assembly was studied by SEM, FTIR, and ESI-MS.

Force-induced fibronectin fibrillogenesis in vitro
Jens Ulmer, Benjamin Geiger and Joachim P. Spatz,
Soft Matter, 2008, 4, 1998
DOI: 10.1039/b808020h
Polymerization of fibronectin and its assembly into fibers, in vitro, is a two-step self-assembly process, initiated by the formation of a stable FN sheet made of globular particles at the air–liquid interface, and followed by shear-force driven fibrillogenesis along a superhydrophobic surface made of elastic micropillars.
Effects of shear induced crystallization on the rheology and ageing of hard sphere glasses
N. Koumakis, A. B. Schofield and G. Petekidis,
Soft Matter, 2008, 4, 2008
DOI: 10.1039/b805171b
We present the linear and non-linear rheological responses and ageing of hard sphere colloidal crystals prepared under oscillatory shear and compare them with their glassy counterparts.
Lateral stress relaxation and collapse in lipid monolayers
Luka Pocivavsek, Shelli L. Frey, Kapilanjan Krishan, Kseniya Gavrilov, Piotr Ruchala, Alan J. Waring, Frans J. Walther, Michael Dennin, Thomas A. Witten and Ka Yee C. Lee,
Soft Matter, 2008, 4, 2019
DOI: 10.1039/b804611e
Monolayer collapse is shown to be a function of their material properties: rigid layers respond elastically by forming large scale out-of-plane folds, softer layers relax in-plane by shearing.

Matteo Ricci, Roberto Berardi and Claudio Zannoni,
Soft Matter, 2008, 4, 2030
DOI: 10.1039/b804782k
Monte Carlo simulations of bowl-shaped mesogens provide insights into the polar columnar domains they form, their polydispersity, and the role of packing defects in terminating the columns.
