Dramatic Mobility Enhancements in Doped SrTiO3 Thin Films by Defect Management

open access: yes, 2010
We report bulk-quality n-type SrTiO3 (n-SrTiO3) thin films fabricated by pulsed laser deposition, with electron mobility as high as 6600 cm2 V-1 s-1 at 2 K and carrier density as low as 2.0 x 10^18cm-3 (~ 0.02 at.

Fabrication of transparent conducting amorphous Zn–Sn–In–O thin films by direct current magnetron sputtering [PDF]

open access: yes, 2007
Amorphous ZnO–SnO2–In2O3 films were grown by direct current magnetron sputtering from vacuum hot pressed ceramic oxide targets of Zn:In:Sn cation ratios 1:2:1 and 1:2:1.5 onto glass substrates.

Biophysical Properties of Lumbricus terrestris Erythrocruorin and Its Potential Use as a Red Blood Cell Substitute

open access: yesJournal of Functional Biomaterials, 2012
Previous generations of hemoglobin (Hb)-based oxygen carriers (HBOCs) have been plagued by key biophysical limitations that result in severe side-effects once transfused in vivo, including protein instability, high heme oxidation rates, and nitric oxide (

Majority-Carrier Mobilities in Undoped and \textit{n}-type Doped ZnO Epitaxial Layers

open access: yes, 2005
Transparent and conductive ZnO:Ga thin films are prepared by laser molecular-beam epitaxy. Their electron properties were investigated by the temperature-dependent Hall-effect technique.

A pH Dependant Switch in DHP Oxidation Mechanism [PDF]

open access: yes, 2017
Dehaloperoxidase (DHP) is a multifunctional enzyme found in Amphitrite ornata, a sediment-dwelling marine worm. This enzyme possess the structure of a traditional hemoglobin enzyme and serves as the primary oxygen carrier in A.

Influence of oxygen ordering kinetics on Raman and optical response in YBa_2Cu_3O_{6.4}

open access: yes, 1995
Kinetics of the optical and Raman response in YBa_2Cu_3O_{6.4} were studied during room temperature annealing following heat treatment. The superconducting T_c, dc resistivity, and low-energy optical conductivity recover slowly, implying a long ...
