High surface area ZnO-carbon composite tubular arrays based on the Kirkendall effect and in situ Zn evaporation.

High surface area ZnO-carbon composite tubular arrays on a ceramic substrate were successfully synthesized by a hydrothermal process and a subsequent nanoscale diffusion-related reaction within the carbonaceous species-coated ZnO rod arrays during 900 degrees C annealing.

A novel glucose sensor based on monodispersed Ni/Al layered double hydroxide and chitosan.

A novel cheap and simple amperometric glucose biosensor, based on the electrode modified with the Ni/Al layered double hydroxide (LDH) nanoflakes and chitosan (CHT), without glucose oxidase, is presented. The glucose biosensor based on monodispersed high active Ni/Al-LDH nanoflakes and CHT exhibits an appropriate linear range of 0.01-10mM and good operational stability.
