ERRATUM: Bright-White Beetle Scales Optimise Multiple Scattering of Light

Probing fractal magnetic domains on multiple length scales in Nd2Fe14B.

Using small-angle neutron scattering, we demonstrate that the complex magnetic domain patterns at the surface of Nd2Fe14B, revealed by quantitative Kerr and Faraday microscopy, propagate into the bulk and exhibit structural features with dimensions down to 6 nm, the domain wall thickness. The observed fractal nature of the domain structures provides an explanation for the anomalous increase in ...

Hybrid Supramolecular and Colloidal Hydrogels that Bridge Multiple Length Scales†

Hybrid nanocomposites were constructed based on colloidal nanofibrillar hydrogels with interpenetrating supramolecular hydrogels, displaying enhanced rheological yield strain and a synergistic improvement in storage modulus. The supramolecular hydrogel consists of naphthyl-functionalized hydroxyethyl cellulose and a cationic polystyrene derivative decorated with methylviologen moieties, physica...

Utilization and control of bioactuators across multiple length scales.

In this review, we summarize the recent developments in the emerging field of bioactuators across a multitude of length scales. First, we discuss the use and control of biomolecules as nanoscale actuators. Molecular motors, such as DNA, kinesin, myosin, and F1-ATPase, have been shown to exert forces in the range between 1 pN to 45 pN. Second, we discuss the use and control of single and small c...

A phenomenological description of BslA assemblies across multiple length scales

Intrinsically interfacially active proteins have garnered considerable interest recently owing to their potential use in a range of materials applications. Notably, the fungal hydrophobins are known to form robust and well-organized surface layers with high mechanical strength. Recently, it was shown that the bacterial biofilm protein BslA also forms highly elastic surface layers at interfaces....
