the effect of european black alder (alnus glutinosa l.) on the contents of carbon and nitrogen,exchangeable base cations, and plant available forms of phosphorus in the reclaimed mine soils formed bywaste deposition from opencast lignite mines was researched in central serbia. it was concluded that thegreatest part of dead organic residues reaching the soil under european black alder monocultur...

This work was designed to understand the mechanisms of adsorption of copper (Cu) and cadmium (Cd) on roots of indica and japonica varieties of rice. Six varieties each of indica and japonica rice were grown in hydroponics and the chemical properties of the root surface were analyzed, including surface charges and functional groups (-COO- groups) as measured by the streaming potential and attenu...

We evaluated the effects of soil washing with ferric chloride (FeCl3) on cadmium (Cd) concentrations in soil solutions and Cd absorption by two spinach cultivars in pot experiments. Soil samples were collected from washed and unwashed plots of rice paddy fields in Fukuoka and Toyama, Japan. Spinach pot cultivation was performed with the above mentioned soil under oxidative conditions. Before an...

Cantharellus formosus is one of the most abundantly collected commercial mushrooms in western North America. Despite its importance to commercial harvesting, little information is known about the habitat requirements of C. formosus. The purpose of this study was to identify the environmental factors that correlate with the distribution of the basidiomata of C. formosus. Fifty-®ve plots (5 m 5 m...

The preparation of MOFs including a metal with an easily exchangeable oxidation state, while maintaining the same crystal structure and stability, is paramount importance for myriad applications. In this work, new synthesis method reported that can be used to prepare Ce/Zr-MOFs (UiO-66 structure) having only Ce(III), mixed-valence Ce(IV)/Ce(III), or Ce(IV) cations, as desired. materials are cha...

The understanding of the structural formula smectite minerals is basic to predicting their physicochemical properties, which depend on location cation substitutions within 2:1 layer. This implies knowing correct distribution and positions cations, allows assigning source layer charge tetrahedral or octahedral sheet, determining total number cations and, consequently, type smectite. However, som...
