Singh's work pointed out that the higher catalytic activity of the energetic additives on the thermal decomposition of AP might be attributed to the active metal
oxides formed in situ in the system .
Willson knew that calcium was a more active metal
than aluminum and he hoped that it would strip oxygen away from the aluminum oxide.
The nitrate catalyst can decompose and generate active metal
Co, Ni, and Fe particles at high temperature.
These process oils give corrosion protection under normal circumstances but once removed atmospheric corrosion can occur very quickly as mechanical production processes remove the oxide layers which form a natural protective coating exposing active metal
surface to rusting and corrosion.
The Ceramospher HPLC column features optical-resolution packing material with high selectivity created from a spherical clay mineral carrying an optically active metal
What the book lacks in the uniqueness of content/ideas, it makes up for with the sheer energy of the prose, an apt reflection of Richard's own 'Francium' (most active metal
on earth) personality.
Asthana, "Active metal
brazing of titanium to high-conductivity carbon-based sandwich structures," Materials Science and Engineering A, vol.
An electronic modification of active metal
like Pd may be introduced by an interaction with a promoter or by Pd-Ag alloy formation.
Among the topics are strength and margins of brazed joints, brazing diamonds and cubic boron nitride, active metal
brazing of advanced ceramic composites to metallic systems, coating techniques using brazing, and the fluxless brazing of aluminum
"Titanium is an active metal
and it is oxidized quickly and forms a sticky layer of titanium oxide on the surface of titanium, which prevents the next stages of the reaction.
The rapid biosorption rate observed in the beginning of biosorption process can be attributed to the increased number of active metal
binding sites on the biosorbent surface, resulting in an increased concentration gradient between sorbate in the solution and on the biomass surface.
Meanwhile, active brazing does not require a metalized layer because it is a method that enables direct joining to ceramics with a single application of heat by improving the wettability (ease of application) to ceramics by adding active metal
such as Ti, zirconium (Zr), hafnium (Hf), etc.
