The prepared polymer was washed several times with 1 4 (v/v) methanol/water to remove the unreacted materials, and then palladium ions (PdCl4 2−) was leached from the polymer material by stirring with 4 × 50 ml of 1 1 HCl for 24 h until the washing solution was free from palladium ions.
Given that this trio could make sterling work of such material while stirring their tea with the other hand, it was hard not to level charges of laziness.
Mr. Hawes has called the material "graphic," stirring controversy in scholarly circles and enraging experts who believe the subject is irrelevant or overblown — either because of the "who cares?" factor or because the material itself is tame by today's standards: decorative woodcuts, playful etchings and Art Nouveau pen-and-ink drawings.
Soil disturbance can be broadly defined as anything that would create direct contact with the material by stirring it up such as digging in it for play or use in road repair.
Synthesis of mesoporous materials without stirring is a unique approach for interacting reagents under stagnant conditions.
The main difference between the FSW of similar and dissimilar alloys is the incoherency in properties across the butting surfaces which has a significant influence on the flow behavior of materials during stirring.
But as the first large-scale public showing of artifacts from the collection, it offers a tantalizing glimpse of material that is stirring the interest not just of hard-core Deadheads but also of scholars.
It is attributed to the attainment of balance state of heat generation and material flow during stirring.
In this study, based on orthogonal tests, the effect of the ratio of material to water, stirring time and stirring speed on the viscosity, filtration property, water retention and pumpability of the FG were studied.
As mentioned earlier, if the processing conditions, i.e. weld travel speed, tool rotation, etc., fail to generate the required heat for bonding, inadequate material mixing and stirring can occur, resulting in the formation of tunnel defects (Grujicic et al. 2010).
