We present a non-oxidative production route to few layer graphene via the electrochemical intercalation of tetraalkylammonium cations into pristine graphite. Two forms of graphite have been studied as the source material with each yielding a slightly different result. Highly orientated pyrolytic graphite (HOPG) offers…
Self-healing polymeric materials are systems that after damage can revert to their original state with full or partial recovery of mechanical strength. Using scaling theory we study a simple model of autonomic self-healing of unentangled polymer networks. In this model one of the two end monomers of each polymer chain…

The surface of a thin liquid film with nonconstant curvature flattens as a result of capillary forces. While this leveling is driven by local curvature gradients, the global boundary conditions greatly influence the dynamics. Here, we study the evolution of rectangular trenches in a polystyrene nanofilm. Initially, wh…

Grain size increases when crystals respond to dynamic equilibrium in a saturated solution. The pathway to coarsening is generally thought to be driven by Ostwald ripening, that is, simultaneous dissolution and reprecipitation, but models to describe Ostwald ripening neglect solid−solid interactions and crystal shapes.…

The development of fluorescent indicators represented a revolution for life sciences. Genetically encoded and synthetic fluorophores with sensing abilities allowed the visualization of biologically relevant species with high spatial and temporal resolution. Synthetic dyes are of particular interest thanks to their hig…
To improve the fire retardancy of acrylonitrile-butadiene-styrene copolymers (ABS), an important engineering thermoplastic, graphite is used by Dan-Dan Yang et al. on page 3038 to reduce the peak heat release rate. The cover image shows organophilic alpha-zirconium phosphate (OZrP)/ABS nanocomposites, synthesized by m…
Abstract Invited for the cover of this issue is the group of Wenfang Sun at North Dakota State University (NDSU), USA. The cover image illustrates the reverse saturable absorption (RSA) mechanism.
Although the cation-pi pair, formed between a side chain or substrate cation and the negative electrostatic potential of a pi system on the face of an aromatic ring, has been widely discussed and has been shown to be important in protein structure and protein-ligand interactions, there has been little discussion of th…

This specification covers one weight and type of para-aramid webbing.
In pursuit of scientific inquiry into the physics of the universe, one encounters a phase at which reversibility plays an important role. Quantum mechanics and the Maxwell’s Demon are some salient indicators of this intriguing facet of Nature. Equally intriguing, a pursuit of scientific inquiry into the thermodynamic…

The type of crystal habit formed depends on the symmetry of the crystal unit cell. For unit cells characterized by low rotational symmetry, single crystals with low symmetry are formed. The cause of the formation of rounded lateral habits in polyethylene (PE) and in polymer single crystals in general is unknown, and s…
The presence of disorder in crystals gives rise to a diffuse, continuous scattering in diffraction patterns. Disorder, in fact, may cause broadening of Bragg reflections and a decrease of the maximum height of the peak intensity. However, for any Bragg reflection whose intensity is affected by disorder, the intensity…
