Abstract

This manuscript describes the synthesis of magnetic composite adsorbents which consist of carbon matrix and magnetic nanoparticles. The carbon matrix originated from simultaneous decomposition and activation of two different precursors, namely glucose and sucrose. KOH and ZnCl2 were used as the activating agents. The inclusion of carbon-encapsulated iron nanoparticles in the course of the synthesis process resulted in mobile composite adsorbents which can be easily separated. The structural features of carbon-encapsulated iron nanoparticles make the developed composite resistant to aggressive corrosion agents. The adsorption performance of the composites was studied in the removal of phenolic compounds from aqueous solutions. [ABSTRACT FROM AUTHOR]

Abstract

The carbon coating in carbon-encapsulated magnetic nanoparticles is considered as a tight and impermeable barrier which should perfectly protect the magnetic core material from external chemical environment. To study the integrity of the coating, carbon-encapsulated iron nanoparticles were subjected to corrosion tests, in which various corrosion agents were used. Several mineral and organic acids, as well as active gaseous environments with various oxidation potential, were applied. Additionally, the corrosion resistance was studied under the so-called galvanic corrosion, using two metal ions (copper and silver) which have higher redox potential than the zero-valent iron. The release of iron from the core as well as the morphology, structural features, chemical composition, and magnetic properties of carbon-encapsulated iron nanoparticles was systematically monitored at each stage of the corrosion process. The largest release of Fe from the encapsulate core was observed when nitric acid was used as the corrosion agent. [ABSTRACT FROM AUTHOR]

Abstract

Cerium-doped yttrium aluminum garnet can be used in white light emitting diodes and lasers. The YAG powders are traditionally formed by the solid state method, but the product particles are large, irregular, and non-homogeneous, which is detrimental for its luminescence properties. We present here a simple and fast method for synthesizing YAG:Ce3+ nanopowder based on solution combustion synthesis from metal nitrates (Ce content between 0.7 and 35 wt%) and fuel (urea, starch, or glucose) water mixtures. The calcination of the raw product at 900 °C for 2 h yielded crystalline garnet nanopowder with grain size well below 100 nm. The properties of the final product were characterized by XRD, SEM, ATR, TG/DTA, and spectrofluorimetric measurements. [ABSTRACT FROM AUTHOR]

85. Addition of azomethine ylides to carbon-encapsulated iron nanoparticles.

Author

Kasprzak A, Nowicka AM, Sek JP, Fronczak M, Bystrzejewski M, Koszytkowska-Stawinska M, and Poplawska M

Abstract

The Prato reaction was applied for the covalent introduction of a variety of organic moieties onto carbon-encapsulated iron nanoparticles. The developed method is versatile and employs a broad range of commercially available reactants, including both aromatic and aliphatic aldehydes. The reported functionalization route provides high functionalization yields (ca. 12-21 wt%).

86. Nanoplatforms for magnetic resonance imaging of cancer.

Author

Abstract

The application of biomedical nanotechnology in magnetic resonance imaging (MRI) is expect to have a major impact leading to the development of new contrast drug candidates on the nanoscale (1-100 nm) that are able to react with specific biological targets at a molecular level. One of the major challenges in this regard is the construction of nanomaterials, especially used in molecular MRI diagnostics of cancer in vivo, specialized antitumor drug delivery or real-time evaluation of the efficacy of the implemented cancer treatment. In this paper, we tried to gain further insights into current trends of nanomedicine, with special focus on preclinical MRI studies in translation cancer research.
