Coordinated Architectural and Chemical Reinforcement in the Crushing Mandible of a Soldier Termite
Advanced Functional Materials, EarlyView.The crushing mandible of a soldier termite withstands substantial biting loads despite lacking mineral. Its cuticle is partitioned: convex teeth pair hardness and zinc enrichment with aligned chitin fibers for contact durability, while stiffer concave regions between teeth carry bending loads.

TEM analysis of the internal structures and mineralogy of Asian dust particles and the implications for optical modeling [PDF]
Atmospheric Chemistry and Physics, 2014 Mineral dust interacts with incoming/outgoing electromagnetic radiation in the atmosphere. This interaction depends on the microphysical properties of the dust particles, including size, mineral composition, external morphology, and internal structure ...

Chitin‐Derived Carbon‐Metal Functional Materials
Advanced Functional Materials, EarlyView.Functional carbon materials are synthesized from combination of biopolymer (chitin) and iron precursors. The resultant material exhibits superior surface area and adsorptive properties compared to carbon materials synthesized directly from pure chitin.

Mineral properties and their contributions to particle toxicity.
Environmental Health Perspectives, 1997 It has been recognized since at least as early as the mid-1500s that inhaled minerals (i.e., inorganic particles) can pose a risk. Extensive research has focused on the biological mechanisms responsible for asbestos- and silica-induced diseases, but much less attention has been paid to the mineralogical properties and geochemical mechanisms that might ...

Advanced Functional Materials, EarlyView.The liposome nanoreactor method enables uniform metal nanoparticle synthesis using the interior as a reaction environment. We demonstrate that peptide sequences and lipid compositions act as a functional molecular switch to control reaction environments in liposome nanoreactors.
