Development of vibration loading profiles for accelerated durability tests of ground vehicles
The accelerated durability test is an important part for design and manufacturing ground vehicles. It consists of test designed to quantify the life characteristics of a ground vehicle component under normal use conditions by testing the unit at higher stress levels to accelerate the occurrence of …

Ruthenium-Chromium Oxide Aerogels Oxygen Evolution Electrocatalysts: Structure, Activity and Stability
… the activity remained higher than RuO2 after an accelerated durability test. The Ru-600 catalyst exhibited higher stability than the commercial RuO2 after the accelerated durability test. This work shows that chromium introduced into ruthenium oxide aerogels provides high surface area and …

Study of catalysts with high stability for proton exchange membrane fuel cells
… Emmett and Teller (BET) method was applied to test the surface area of the catalysts. The electrochemical surface area (ECSA) and mass activity during oxygen reduction reaction (ORR) process for two kinds of catalyst were tested by cyclic voltammetry method under different conditions. The …
