The clarifying effect of using bis-oxalamide compounds on linear low density polyethylene (LLDPE) has been investigated for the first time. It was demonstrated that the haze of a commercial LLDPE resin, DOWLEX™ 2045G, can be reduced up to 50% by ad

In recent years, the prevalence of hydrogel-like organic matrices in biomineralization has gained attention as a route to synthesizing a diverse range of crystalline structures. Here, examples of hydrogels in biological, as well as synthetic, bio-ins

Biogenic single-crystal composites, such as sea urchin spines and calcitic prisms from mollusk shells, contain organic macromolecules inside of inorganic single-crystal matrices. The nanoscale internal structure of these materials, however, is poorly

Previous results have shown that the nacre specific peptide, n16N, from the Japanese pearl oyster Pinctada fucata has a binding affinity for β-chitin. As a result, the n16N-chitin assembly is able to selectivity nucleate aragonite. Here, we have add

The formation of calcite prism architecture in the prismatic layer of the mollusk shell involves the participation of a number of different proteins. One protein family, Asprich, has been identified as a participant in amorphous calcium carbonate sta

Previous literature by Falini et al. suggests that the cooperation between β-chitin, proteins, and a silk fibroin-like hydrogel determines polymorph selectivity within the nacreous layer of mollusk shells (favoring aragonite over calcite formation).

We have made measurements of force and velocity fluctuations in a variety of dense, gravity-driven granular flows under flow conditions close to the threshold of jamming. The measurements reveal a microscopic state that evolves rapidly from entirely
