AB  - Investigating magnetic properties of nanoparticles dispersed in a fluid is catching an increasing attention for their wide range of applications; however, a careful magnetic characterization requires low temperatures and vacuum conditions which represent a critical issue for a correct sample handling. In this paper, several experimental protocols to investigate low temperature magnetic properties of magnetic nanoparticles dispersed in fluid are described. In particular, by investigating interparticle interaction by remanence techniques at low temperature, some insight about particle aggregation in fluids has been given. © 2018 IEEE.

AB  - Initial results en route toward construction of complex magnetic core-shell silica and organosilica nanotheranostics are presented. Magnetite nanoparticles are synthesized by three different methods and embedded within mesoporous silica and organosilica frameworks by different surfactant-templated procedures to produce three types of core-shell nanoparticles. Magnetite nanoparticles (15 nm in diameter) are embedded within mesoporous silica nanoparticles to produce cell-like material with predominantly one magnetite nuclei-resembling core per nanoparticle, with final particle diameter of ca. 150 nm, specific surface area of 573 m(2)/g and hexagonally structured tubular pores (2.6 nm predominant diameter), extended throughout the volume of nanoparticles. Two forms of spherical core-shell nanoparticles composed of magnetite cores embedded within mesoporous organosilica shells are also obtained by employing ethylene and ethane bridged organobisalkoxysilane precursors. The obtained nanomaterials are characterized by high surface area (978 and 820 m(2)/g), tubular pore morphology (2 and 2.8 nm predominant pore diameters), different diameters (386 and 100-200 nm), in case of ethylene- and ethane-composed organosilica shells, respectively. Different degree of agglomeration of magnetite nanoparticles was also observed in the obtained materials, and in the case of utilization of surfactant-pre-stabilized magnetite nanoparticles for the syntheses, their uniform and non-agglomerated distribution within the shells was noted.

AB  - We present here some recent research advancements and opportunities within the FP7-ERA Chairs MagBioVin project. The project aims to design various novel magnetic nanoarchitectures (e.g. bimagnetic and polymeric core-shell systems, nanoparticles embedded in mesoporous silica and radiolabeled nanostructures) for application in targeted treatment and diagnostics of cancer. The magnetic core of these nanomaterials allows the selective treatment of tumor tissues (i.e. targeted drug-delivery, localized magnetic hyperthermia) by magnetic field. Attachment of radionuclides (e.g. 90Y, 99mTc, 134I) to the nanoparticles opens the possibilities for imaging and internal radiotherapy. Magnetic nanoparticles (MNPs), i.e. iron oxides and spinel ferrites, were synthesized by different methods and coated by several compounds (e.g. citrate, polymers, silica, BSA) to increase their biocompatibility. The composition and morphology of the nanomaterials is characterized by XRD, TEM imaging and infrared spectroscopy, while their magnetic properties were studied by SQUID magnetometry and Mössbauer spectroscopy. Magnetic hyperthermia effects were monitored by DM100 device equipped with DM1, 2 and 3 applicators (nB nanoScale Biomagnetics). This unique setup allows us to monitor the heating efficiency development in cell cultures and small animals (e.g. mice, rats) as well. The current results showed that the MNPs can be successfully labeled with 90Y and 99mTc. The drug loading and release properties of MNPs are studied by HPLC using doxorubicin as the drug. In vitro and in vivo (animal model) applicability of the synthesized nanomaterials regarding toxicity, biodistribution and anti-cancer efficacy is explored for targeted cancer treatment.

AB  - The title compound, C39H30O6 center dot CDCl3, has a chemical threefold axis and an approximately planar structure, with an ethoxycarbonyl substituent on each of the terminal benzenes oriented in the same direction, thus forming a propellershaped molecule. This molecule is of particular interest in the field of metal-organic frameworks (MOFs), where its hydrolyzed analogue forms MOF structures with high surface areas. The benzene ring which occupies the centre of the molecule forms pi-pi interactions to the equivalent benzene ring at a perpendicular distance of 3.32 (1) angstrom. Centrosymmetric dimers formed in this way are interconnected by intermolecular C-H center dot center dot center dot pi interactions with a rather short H center dot center dot center dot CgA distance of 2.51 angstrom (CgA is the centroid of the central benzene ring). The molecules are arranged in regular parallel sheets. Within a sheet, molecules are interconnected via C-H center dot center dot center dot O interactions where all carbonyl O atoms participate in weak hydrogen bonds as hydrogen-bond acceptors. Neighbouring sheets are connected through the above-mentioned pi-pi and interactions.
