Mechanical properties of self-assembled chitin nanofiber networks - Journal of Materials... Chitin nanofibers are structural components of the insect cuticle, the exoskeleton of crabs, and mollusk shells. Chitin nanofibers have found broad use in biomedical applications. Here, we study structure–properties–processing relationships of 3 nm chitin nanofiber networks self-assembled from a chi...

Yingxin's paper on "H+ -type and OH− -type biological protonic semiconductors and complementary devices" is published online at Scientific Reports: http://www.nature.com/srep/2013/131003/srep02481/full/srep02481.html

H+-type and OH−-type biological protonic semiconductors and complementary devices : Scientific... Proton conduction is essential in biological systems. Oxidative phosphorylation in mitochondria, proton pumping in bacteriorhodopsin, and uncoupling membrane potentials by the antibiotic Gramicidin are examples. In these systems, H+ hop along chains of hydrogen bonds between water molecules and hydr...
