Poisoning Effects of Cerium Oxide (CeO2) on the Performance of Proton Exchange Membrane Fuel Cells (PEMFCs)

Jan Van Herle, Hossein Pourrahmani

In this study, the poisoning effects of cerium oxide (CeO2) as the contaminant on the performance of proton exchange membrane fuel cells (PEMFCs) are evaluated. An experimental setup was developed to analyze the performance characteristic (I-V) curves in c ...

A Crevice Corrosion Model for Biomedical Trunnion Geometries and Surfaces Feature

Stefano Mischler, Anna Neus Igual Muñoz, Angela Bermudez Castañeda

Modular hip joint implants were introduced in arthroplasty medical procedures because they facilitate the tailoring of patients’ anatomy, the use of different materials in one single configuration, as well as medical revision. However, in certain cases, su ...

Multiaxial fatigue behavior and strengthening of riveted double-angle connections in steel bridges using prestressed CFRP rods

Hossein Heydarinouri

A large number of aging road and railway riveted metallic bridges suffer from fatigue problems. Stringer-to-floor-beam double-angle bridge connections are among the most fatigue-prone details due to the many cyclic distortion-induced stresses from axle loa ...

Fretting-corrosion behavior of electroless Ni-P/Ni-P-TiO2 coatings obtained on AZ91D magnesium alloy by a chromium-free process

Stefano Mischler, Angela Bermudez Castañeda

Ni-P electroless coatings are widely applied for protection of magnesium alloys and other materials due to the low energy consumption of the process and high resistance to corrosion and wear, properties that can be improved with the incorporation of partic ...

Tribocorrosion of a CoCrMo alloy in sulfuric acid - Glycerol mixtures

Stefano Mischler, Shoufan Cao

This work reports on the tribocorrosion properties of a CoCrMo alloy sliding under imposed passive potential against alumina in sulfuric acid-glycerol mixtures exhibiting different viscosities and thus, in principle, lubrication properties. As expected, we ...

Influence of Bovine Serum Albumin (BSA) on the Tribocorrosion Behaviour of a Low Carbon CoCrMo Alloy in Simulated Body Fluids

Stefano Mischler, Shoufan Cao, Choshun Yoneyama

Tribocorrosion, as the interaction between mechanical wear and electrochemical corrosion, has been found to be the main problem causing the failure and limiting the lifetime of metal-on-metal artificial hip joints. Better understanding of the tribocorrosio ...

Tensile response of textile reinforced concrete

Aurelio Muttoni, Miguel Fernández Ruiz, Patrick Lorenzo Valeri

Textile Reinforced Concrete (TRC) is a cementitious composite material where a carbon or glass fabric is embedded as reinforcement. The use of TRC allows building thin and light structures, with reduced concrete covers and an enhanced durability due to the ...

Tribological properties of gold matrix composite coatings with carbon nanocapsules containing ionic liquid lubricants

Stefano Mischler, Anna Neus Igual Muñoz

Self-lubricating, gold matrix composite coatings were produced by electrochemical codeposition of carbon nanocapsules filled with ionic liquid (IL) from a colloidal galvanic bath on a nickel electrode. The tribological response of the composite coatings wa ...

Iodic acid, sulfuric acid and methanesulfonic acid collected during the Arctic Ocean 2018 expedition

Julia Schmale, Andrea Baccarini

Measurements of iodic acid, sulfuric acid and methanesulfonic acid concentration in the gas phase obtained with a nitrate chemical ionization mass spectrometer (we used an APi-TOF mass spectrometer produced by Tofwerk AG coupled with a Chemical ionization ...

Tribocorrosion behaviour of pure titanium in bovine serum albumin solution: A multiscale study

Anna Neus Igual Muñoz

Tribocorrosion behaviour of pure titanium in phosphate buffer saline (PBS) solution has been investigated systematically as a function of surface chemistry and bovine serum albumin (BSA) content in the solution. A ball-on-disk tribometer coupled with an el ...
