Mechanical performance during

Celina et al. [98] have recently investigated the correlation between the content of the antioxidant 2,2 -methylene-bis-(4-methyl-6-ferf-butylphenol) in polybutadiene and the mechanical performance during aging at tempera-... 

In situ studies of the growth mechanism performed during the deposition of nanotubes from the gas phase revealed that carbon preferably attaches to steps on the crystal surface of the catalyst particles, thus initiating the formation of graphene layers. The continually changing shape of the metal particle also contributes to this process as it is generating new active centers all the time. 

The aim of this research was to obtain new clarifications regarding the preponderant reactions responsible for the PU consolidation process and to study the evolution of the PUs mechanical performance during the post cure process in correlation with the dynamics of different diffusion processes like water absorption and CO2 desorption. 

Throughout the global stratosphere, many of the photochemical mechanisms remain untested. Although certain reactions are clearly occurring, they may not be the only reactions. A simple example is a test for the balance between the production and the destruction of ozone, as represented by equation 8. No experiment has yet been performed during which the abundances of all the rate-limiting components for ozone loss and ozone production, N02, H02, CIO, BrO, and O, have been measured. 

Post-industrial waste and sorted post-consumer wastes (PCW) are suitable raw materials. However, they contain different amounts of inhomogeneities formed during the service life and non-polymeric impurities. These contaminants account for differences in mechanical properties and ageing resistance between recyclates and the respective virgin plastics. Recycled plastics are often used in low-grade applications, and it is generally believed that the mechanical performance of recyclates is lower than that of virgin materials.
