Leaf anatomical characteristics are less important than leaf
Abstract. The photosynthetic capacity of leaves is dramatically influenced by nitrogen (N) availability in the soil, as CO 2 concentration in chloroplasts and photosynthetic biochemical capacity are related to leaf N content. The relationship between mesophyll conductance (g m) and leaf N content was expected to be shaped by leaf anatomical …

The use of chlorination for iron and titanium removal from different clay and kaolin minerals, used in Argentinian ceramic industry, has been investigated to establish reaction mechanisms, precautions and optimal conditions to bleach the clays. The method consists of the calcinations of the pellets in a flow of chlorine gas at temperatures ...
Recovery of gold from secondary sources—A review
Kogan (2006) patented a technique for gold recovery from waste electronic equipment. The scrap was added to hydrochloric solution containing 180 g/L HCl and 250 g/L MgCl 2 for 3 h at a temperature of 80–95 °C. During this period 98% of aluminum, 94% of tin, 96% of lead and 94% of zinc were extracted in solution.
