Influence of oxygen partial pressure on the microstructural and magnetic properties of Er-doped ZnO thin films

open access: yesAIP Advances, 2015
Er-doped ZnO thin films have been prepared by using inductively coupled plasma enhanced physical vapor deposition at different O2:Ar gas flow ratio (R = 0:30, 1:30, 1:15, 1:10 and 1:6).

Reverse water gas-shift reaction product driven dynamic activation of molybdenum nitride catalyst surface

open access: yesNature Communications
In heterogeneous catalysis catalyst activation is often observed during the reaction process, which is mostly attributed to the induction by reactants. In this work we report that surface structure of molybdenum nitride (MoN x ) catalyst exhibits a high ...

Oxygen partial pressure induced effects on the microstructure and the luminescence properties of pulsed laser deposited TiO2 thin films

open access: yesAIP Advances, 2017
In this work, the influence of oxygen partial pressure on structural, morphological, and optical properties of TiO2 thin films grown on fused quartz substrate at different oxygen partial pressure by pulsed laser deposition were examined.

Thermodynamic formalism for the Lorentz gas with open boundaries in $d$ dimensions

open access: yes, 2004
A Lorentz gas may be defined as a system of fixed dispersing scatterers, with a single light particle moving among these and making specular collisions on encounters with the scatterers.

Total and Partial Pressure Measurement

open access: yes, 2020
Total pressure gauges are used to measure the level of vacuum in a system independent of the gas species. Partial pressure analysers measure the occurrence of each gas species separately. This report explains the methodology of measurement, summarizes the measurement principles of total pressure vacuum gauges, and updates the standardization work for ...

Bladder acellular matrix graft: in vivo functional properties of the regenerated rat bladder. [PDF]

open access: yes, 1999
The purpose of this study was to determine whether the rat urinary bladder augmented by an acellular matrix graft can restore the bladder's low-pressure reservoir function and preserve normal micturition.
