Mechanism of defects and electrode structure on the performance of AlN-based metal semiconductor metal detectors

open access: yesMaterials Research Express, 2021
We used the metal-organic chemical vapor deposition(MOCVD) method to grow AlN material on a c-plane sapphire substrate and fabricate an AlN-based metal-semiconductor-metal (MSM) detector.

Intracellular Metal Detectors [PDF]

open access: yesACS Chemical Biology, 2006
Metal ions play numerous crucial roles in biology, and there is great interest in obtaining an accurate measurement of the intracellular concentrations of both tightly bound and exchangeable metal ions. Measuring the concentration of readily exchangeable transition metal ions in a cell has been particularly difficult because of the extremely small ...

Bacterial metal detectors [PDF]

open access: yesMolecular Microbiology, 2005
SummaryGram negative bacteria can detect environmental iron using outer membrane transporters (OMTs), and then regulate certain transport genes to take advantage of a readily available iron source. This process begins with an iron complex being bound by an OMT, and results in a signal being sent across the outer membrane, the periplasmic space, and the
