On the physical mechanism of tip vortex cavitation hysteresis

Mohamed Farhat, Matthieu Dreyer, Ali Amini, Martino Reclari

Inception and desinence thresholds of tip vortex cavitation (TVC), generated by an elliptical NACA 16-020 hydrofoil, are measured at different flow conditions for various gas contents. It is observed that TVC often disappears at cavitation indices signific ...

Hydrogen sieving from intrinsic defects of benzene-derived single-layer graphene

Kumar Varoon Agrawal, Mostapha Dakhchoune, Shiqi Huang, Jing Zhao, Mina Moradi, Majharul Haque Khan

Single-layer graphene films, crystallized by chemical vapor deposition, host a low density of vacancy defects that are attractive for the size-sieving of molecules. The size and the density of such defects are a function of the growth temperature and the c ...

Methane oxidation over a honeycomb Pd-only three-way catalyst under static and periodic operation

Davide Ferri, Oliver Kröcher

Natural gas is receiving increasing awareness as fuel for passenger vehicles due to its very low specific CO2 emissions. However, control of CH4 emissions from natural gas combustion in stoichiometric engines requires a specific three-way catalyst (TWC). T ...

Reversible Segregation of Ni in LaFe0.8Ni0.2O3 +/-delta During Coke Removal

Davide Ferri, Oliver Kröcher

The deactivation of supported nickel catalysts by coking is an important technological subject for many chemical processes, especially when high concentrations of unsaturated hydrocarbons are present in the feed gas. Here, the reversible segregation of Ni ...

Exergy Recovery During Liquefied Natural Gas Regasification Using Methane as Working Fluid

François Maréchal, Francesco Baldi, Francesca Belfiore

The increased concerns about the effect of human activities on the climate have pushed natural gas among the most obvious solutions for the transition to a low-carbon economy. The growing importance and volumes of liquefied natural gas for transportation o ...

Single-layer graphene membranes by crack-free transfer for gas mixture separation

Andreas Züttel, Duncan Thomas Lindsay Alexander, Emad Oveisi, Kumar Varoon Agrawal, Wen Luo, Mostapha Dakhchoune, Shiqi Huang, Guangwei He, Jing Zhao

The single-layer graphene film, when incorporated with molecular-sized pores, is predicted to be the ultimate membrane. However, the major bottlenecks have been the crack-free transfer of large-area graphene on a porous support, and the incorporation of mo ...
