Purity predictive model-based control of oxygen vacuum swing adsorption process [PDF]

open access: yes18th Mediterranean Conference on Control and Automation, MED'10, 2010
The paper deals with both dynamic modeling and control of the oxygen vacuum swing adsorption (VSA) process. This process is well known for its batch-like operation and inherent non-linearities. The main objectives are to establish a robust dynamic model and then to demonstrate the practical application of a purity predictive model-based control to this

Graphene Nanosheet‐Based Mixed Proton‐Electron Conducting Membranes for Efficient Hydrogen Purification

open access: yesAdvanced Functional Materials, EarlyView.
A monolayer graphene/phosphoric‐acid mixed proton‐electron conducting membrane combines proton‐conducting nanoconfined acid channels with electron‐conducting graphene nanosheets for efficient high‐temperature hydrogen purification. The membrane achieves nearly 100% H2/CO2 selectivity and 69 GPU hydrogen permeance at 250°C, arising from synergistic ...

Silicene Nanomesh

open access: yes, 2015
Similar to graphene, zero band gap limits the application of silicene in nanoelectronics despite of its high carrier mobility. By using first-principles calculations, we reveal that a band gap is opened in silicene nanomesh (SNM) when the width W of the ...
