Gas transport in surface grafted polypropylene films with polyacrylic acid chains
(Wiley, 2007-09-01)
This work describes the grafting reaction of poly(acrylic acid) (PA) onto the
surface of polypropylene (PP) films carried out with ultraviolet radiation, using benzophenone as photoinitiator and water as solvent. By ...

Pd based membrane reactor for ultra pure hydrogen production through the dry reforming of methane. Experimental and modeling studies
(Elsevier Science, 2011-06)
A dense Pd-Ag membrane reactor (MR) with 100% hydrogen selectivity packed with either Rh/La2O3 or Rh/La2O 3-SiO2 as catalysts was used to carry out the dry reforming of methane. The membrane reactor simulation was performed ...
A Comparative Study of Hydrogen-Induced Cracking Resistances of API 5L B and X52MS Carbon Steels
(2018-01-01)
Susceptibility to hydrogen-induced cracking of API 5L B and X52MS low-carbon steels in NACE 177-A, 177-B, and 284-B solutions has been investigated by the present work. A metallographic analysis of these steels was performed ...
The influence of microstructure on the hydrogen embrittlement in martensitic-ferritic stainless steel
(Universidade Federal de Minas GeraisUFMG, 2015-10-29)
This work investigates the interaction of hydrogen with the microstructure in the martensitic-ferritic stainless steel (MFSS). The samples were extracted from hot rolled seamless stainless steel tube after a solution ...
