Effect of pore morphology of mesoporous carbons on the electrocatalytic activity of Pt nanoparticles for fuel cell reactions
Song, S.; Liang, Y.; Li, Z.; Wang, Y.; Fu, R.; Wu, D.; Tsiakaras, P. (2010)In the present investigation, the role of the pore morphology of mesoporous carbons in the electrocatalytic activity of Pt nanoparticles for fuel cell reactions has been successfully revealed by adopting ordered mesoporous ... -
A facile soft-template synthesis of ordered mesoporous carbon/tungsten carbide composites with high surface area for methanol electrooxidation
Wang, Y.; He, C.; Brouzgou, A.; Liang, Y.; Fu, R.; Wu, D.; Tsiakaras, P.; Song, S. (2012)Ordered 2D hexagonal mesoporous carbon/tungsten carbide (OMC/WC) composite nanomaterials have been successfully synthesized for the first time by the soft-template method with ammonium metagungstate as tungsten precursor ... -
Hydrogen induced shear localization of the plastic flow in metals and alloys
Sofronis, P.; Liang, Y.; Aravas, N. (2001)Hydrogen enhanced localized plasticity (HELP) is a viable mechanism for hydrogen embrittlement supported by experimental observations. According to the HELP mechanism, hydrogen induced premature failures result from hydrogen ... -
Mechanics models for hydrogen embrittlement mechanisms
Liang, Y.; Sofronis, P.; Dodds Jr, R. H.; Aravas, N. (2005)Of the many suggestions of hydrogen-induced degradation of engineering materials, two mechanisms appear to be viable in non-hydride forming systems: hydrogen-enhanced localized plasticity (HELP) and hydrogeninduced decohesion. ... -
On the effect of hydrogen on plastic instabilities in metals
Liang, Y.; Sofronis, P.; Aravas, N. (2003)Experimental observations and theoretical calculations have demonstrated that hydrogen solute atoms increase the dislocation mobility in metals and alloys, thus promoting highly localized plastic processes which eventually ... -
Ordered mesoporous tungsten carbide/carbon composites promoted Pt catalyst with high activity and stability for methanol electrooxidation
Wang, K.; Wang, Y.; Liang, Z.; Liang, Y.; Wu, D.; Song, S.; Tsiakaras, P. (2014)The current anode materials used for direct methanol fuel cells (DMFCs) are expensive and not sufficiently durable for commercial development. One of the major challenges lies in the development of an inexpensive, efficient ... -
Recent advances in the study of hydrogen embrittlement at the University of Illinois
Sofronis, P.; Robertson, M.; Liang, Y.; Teter, D. F.; Aravas, N. (2003)This paper summarizes recent work at the University of Illinois on the fundamental mechanisms of hydrogen embrittlement. Our approach combines experimental and theoretical methods. We describe the theoretical work on hydride ...
