Nitrogen Dynamics of Organic Materials Applied to Paddy Fields: Direct Evaluation Using Organic Materials Labeled with Nitrogen-15

Metal-organic framework materials as nano photocatalyst

Photocatalytic degradation of toxic organic compound in water, soil and air by semiconductor catalysts such as TiO2 and ZnO have received much attention over the last two decades. However, the low quantum yield, easy agglomeration and difficult post-separation of these inorganic catalysts limit their application for large-scale applications. Metal-organic frameworks (MOFs) are the latest class ...

Organic Petrology applied to materials and coal by-products characterization

Optical microscopy is a very unique tool to find out about the structural order of carbonaceous materials and coal by-products. It has two main utilization ways as an instrument to distinguish and quantify different phases in a polished surface and as a record of the reflectance of a given material. Using one or both capabilities there are significant contributions to different aspects of coal ...

Metabolism of Labeled Organic Nitrogen in Soil: Regulation by Inorganic Nitrogen

Regulation of organic N metabolism by inorganic N availability was investigated in short-term laboratory incubations of soil. A C-, N-labeled organic N substrate was produced by growing Pseudomonas stutzeri in labeled media and isolating a cytoplasmic fraction. This was added to soils that had been preincubated with glucose or glucose plus NHJ to induce conditions of N deficiency or sufficiency...
