Reassessing the Role of Organic Matter on Metal Transport and Deposition in Chilean Stratabound Cu Deposits
(2017)
In the last few decades, several studies have recognized
the significance of organic matter in mineralizing processes,
in particular, for carbonate-hosted, metal-rich shales and
uranium deposits, among others. Recent ...

Deposição de nutrientes em rã-touro na fase de engorda
(2015-01-01)
Descriptions of nutrient deposition are important to determine the nutritional requirements of animals. The objective of this study was to describe nutrient deposition in the body and legs and the dietary intake of protein ...
Cold spray aluminum–alumina cermet coatings: effect of alumina content
(Springer, 2018)
Deposition behavior and deposition efficiency were investigated for several aluminum-alumina mixture compositions sprayed by cold spray. An increase in deposition efficiency was observed. Three theories postulated in the ...
The improvement of thin polymer film properties through plasma immersion ion implantation and deposition technique
(2001-12-01)
Thin polymer films were deposited from acetylene and argon mixtures by plasma immersion ion implantation and deposition. The effect of the pulse frequency, v, on molecular structure, optical gap, contact angle and hardness ...
