Future military and commercial composite vehicles will have "nano inside" to provide safety, reliability, durability, condition-based maintenance, and multifunctionality.
As concerns frost durability, climatic conditions in southern Finland will ease remarkably already in 2030.
Especially, our own catalysts have a 60% better life as compared to Pt/C under electrochemically accelerated durability test conditions.
These catalysts are very active and selective in the catalytic reduction of NOx with iso-butane; they have a high durability under conditions simulating vehicular emission.
The physical mechanisms of structure-phase states and dislocation substructures evolution and partial restoration of resource durability in conditions of pulse electric current stimulation at the intermediate stage of fatigue curve are established in austenite steels by method of transmission electron microscopy.
Catalytic testing results showed that the catalytic activities over these catalysts followed a descending order of 10% MnOx/HZSM-5-25 > 10% MnOx/HZSM-5-50 > 10% MnOx/HZSM-5-75, where 10% MnOx/HZSM-5-25 exhibithe the optimum catalytic activity and excellent catalytic durability under dry condition and good water-resistant ability under humid condition.
Furthermore, the superhydrophobic surface displayed a robust durability under the condition of 30 icing/deicing cycles.
The relative dynamic modulus and percentage weight loss were used for investigation of the concrete durability in freeze thaw condition.
However, the soil texture may cause imperfect integration due to cement hydration, which negatively affects both durability and aesthetic condition, producing surface cracks and dust scattering, propagates to economic losses.
For the long-term durability under severe condition (<30% RH), the routine single cell manifests a significant voltage decline of about 15.5%.
The design of multifunctional materials with durability under extreme conditions has raised considerable interest for their highly practical potential.
