(Elsevier B.V., 2013-12-01)
This paper presents a chronological study focusing the use of Pb-210 in four sediment cores collected at Ribeirao dos Bagres in the region of Franca, Sao Paulo State, Brazil. When evaluating the sedimentation rate by using ...
Study of adsorption and preconcentration by using a new silica organomodified with [3-(2,2′-dipyridylamine)propyl] groups
(2013-02-01)
In this work, a silica surface chemically modified with [3-(2,2′-dipyridylamine)propyl] groups, named [3-(2,2′- dipyridylamine)propyl]silica (Si-Pr-DPA) was prepared, characterized, and evaluated for its heavy metal ...

High Carbon Ferro-Chromium by Self-Reducing Process
(JOURNAL IRON STEEL RESEARCH EDITORIAL BOARD, 2009)
This paper discusses the effects of temperature, addition of ferro-silicon and fluxing agents for the production of high carbon ferro-chromium by self-reducing process. The use of self-reducing agglomerates for ferro-alloys ...
