The United States on Wednesday imposed 25% tariffs on all steel and aluminum imports, as per an executive order Trump signed on Feb. 10. The U.S. has delayed tariffs on other Mexican goods and ...

This article presents a brief review of the developments in porous α-alumina and amorphous-γ-alumina transition. Most studies have shown that composites and alumina coated with bioactive materials, ...

At higher end point pH values, amorphous aluminum hydroxide was initially formed followed by the cessation of the carbonation reaction and subsequent formation of bayerite. Conversely, at lower end ...

First principles simulation revealed insufficient binding energy between titanium nitride and silicon doped hafnium oxide ferroelectric materials, while introducing an amorphous alumina interface ...

Aluminum hydroxide exists in four highly ordered crystalline polymorphs and one amorphous, or disordered, form. Form turns out to play a big role in the sorbent’s function. “Based on ...

The addition of phosphate ions leads to the formation of aluminum hydroxyphosphate Al(OH)x(PO4)y, in which a percentage of the hydroxyl group is replaced by phosphate. AP adjuvants are amorphous, i.e.

“Compared to single crystal aluminum nitride, amorphous ALD alumina has fewer defects and is less challenging to fabricate, which helped us to achieve lower loss.” To create the microresonators, ...

The fact that amorphous metal is thick and like plastic when molten ... injection-moldable form costs about $15 a pound to make versus roughly $1 a pound for aluminum and 25 cents a pound for steel.
