Synthesis, Characterization and Adsorption Properties of Magnetic γ-Fe2O3/C Nanocomposite.

γ-Fe2O3/C nanocomposite was prepared through a convenient method by which one-pot synthesized Fe3O4/Starch was oxidized and carbonized by calcining at 250 °C. The γ-Fe2O3/C displayed strong magnetism and could adsorb organic molecules from aqueous solution effectively, thus it showed promising application in the dislodgement of organic pollutants in sewage. Adsorption isotherms and kinetics of methylene blue (MB) onto γ-Fe2O3/C were studied in a batch system.

One-step hydrothermal synthesis of FeO@C nanoparticles with great performance in biomedicine.

Core-shell structured FeO@C nanoparticles were fabricated by a facile one-pot hydrothermal route. The structure and component of the nanoparticles were fully characterized by transmission electron microscopy, X-ray diffraction, Mössbauer spectroscopy, Raman spectroscopy, thermogravimetric analysis, magnetometry and Brunauer-Emmett-Teller specific surface area measurements. The obtained FeO@C nanoparticles possessed favorable dispersibility, high saturation magnetization (61.

Coordination polymers for catalysis: enhancement of catalytic activity through hierarchical structuring.

We utilized a novel strategy, hierarchical structuring, to enhance the catalytic activity of coordination polymers. Hierarchical Prussian white crystals with hollow structures and kinked surfaces were synthesized by using a self-aggregation and etching strategy. The hierarchical structure significantly enhanced the catalytic activity of Prussian white in the degradation of methylene blue in comparison to the non-hierarchical Prussian white crystals.

2-Iodo-4,6-dimethyl-pyrimidine.

In the title compound, C(6)H(7)IN(2), the non-H atoms of the mol-ecule are located on a crystallographic mirror plane; the H atoms of the methyl groups are therefore disordered over two positions of equal occupancy. In the crystal structure, short inter-molecular I⋯N contacts [3.390 (3) Å] are found, linking the mol-ecules into zigzag chains.
