the produced liquid water in cathode catalyst layer (ccl) has significant effect on the operation of proton exchange membrane fuel cell (pemfc). to investigate this effect, the transport of oxygen in ccl in the presence of immiscible liquid water is studied applying a two-dimensional pore scale model. the ccl was reconstructed as an agglomerated system. to explore the wettability effects, diffe...

Over the past years, two-dimensional materials such as graphene, phosphorene, silicene, and boron-nitride have attracted the attention of many researchers. After the successful synthesis of graphene, due to its many new applications, researches began to produce nanosheets from other elements, and among these elements, boron was one of the options. In the periodic table of elements, boron is ahe...

The flange climb derailment is one of the cause of derailment for a typical switch. The derailment for the switch is a complex phenomenon since the contact area is changing dynamically. The contact angle between the wheel flange and the switch point is investegated in terms of the risk on the derailment. The contribution of this study is proving that UIC716R standard recommendation about the sw...
