The geometric and electronic structure of the MIL-47(V) metal-organic framework (MOF) is investigated by using ab initio density functional theory (DFT) calculations. Special focus is placed on the relation between the spin configuration and the properties of the MOF. The ground state is found to be antiferromagnetic, with an equilibrium volume of 1554.70 Å(3). The transition pressure of the pr...

The robust gallium carboxylate Ga(OH)(btec)·0.5H2O (MIL-61) is selected as a parent MOF to prepare Ln-MIL-61 by PSM. This work investigates the luminescence of Ln-doped MIL-61 (Ln = Eu3+, Tb3+, Sm3+, Dy3+) in the visible light region. Upon 314 nm excitation, the emission spectra of Eu-MIL-61, Tb-MIL-61 and Eu/Tb-MIL-61 all exhibit their respective strong sharp emission bands. However, Sm-MIL-61...

In this paper, porous metal−organic frameworks (MIL-53 [CrIII (OH).{O2C-C6H4-CO2}.{HO2C-C6H4-CO2H}x]) were hydrothermally synthesized and, then, a hybrid composite of these synthesized porous metal−organic frameworks (MOF) with acid-treated multi-walled carbon nanotubes (MWCNTs) was prepared. The materials were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), Brunau...

OBJECTIVES To demonstrate that the combination of nonviral murine interleukin (mIL) 2 and mIL-12 gene therapy and external beam radiation therapy (XRT) have an enhanced therapeutic effect for the treatment of head and neck squamous cell carcinoma (HNSCC) in an orthotopic murine model and to elucidate the mechanism of action. DESIGN A randomized, controlled study in a murine HNSCC model. INT...

This paper introduces modal independence logic MIL, a modal logic that can explicitly talk about independence among propositional variables. Formulas of MIL are not evaluated in worlds but in sets of worlds, so called teams. In this vein, MIL can be seen as a variant of Väänänen’s modal dependence logic MDL. We show that MIL embeds MDL and is strictly more expressive. However, on singleton team...
