Solvent-modified dynamic porosity in chiral 3D kagome frameworks
No full textExtent: 9p.Dynamically porous metal-organic frameworks (MOFs) with a chiral quartz-based structure have been synthesized from the multidentate ligand 2,2'-dihydroxybiphenyl-4,4'-dicarboxylate (H2diol). Compounds [Ni(II)(H2diol)(S)2]·xS (where S = DMF or DEF) show marked changes in 77 K N2 uptake between partially desolvated [Ni(II)(H2diol)(S)2] (only the pore solvent is removed) and fully desolvated [Ni(II)(H2diol)] forms. Furthermore, [Ni(II)(H2diol)(DMF)2] displays additional solvent-dependent porosity through the rotation of DMF molecules attached to the axial coordination sites of the Ni(II) centre. A unique feature of the four coordinate Ni(II) centre in [Ni(II)(H2diol)] is the dynamic response to its chemical environment. Exposure of [Ni(II)(H2diol)] to H2O and MeOH vapour leads to coordination of both axial sites of the Ni centres and to the generation of a solvated framework, whereas exposure to EtOH, DMF, acetone, and MeCN does not lead to any change in metal coordination or structure metrics. MeOH vapour adsorption was able to be tracked by time-dependent magnetometry as the solvated and desolvated structures have different magnetic moments. Solvated and desolvated forms of the MOF show remarkable differences in their thermal expansivities; [Ni(II)(H2diol)(DMF)2]·DMF displays marked positive thermal expansion (PTE) in the c-axis, yet near to zero thermal expansion, between 90 and 450 K, is observed for [Ni(II)(H2diol)]. These new MOF architectures demonstrate a dynamic structural and colourimetric response to selected adsorbates via a unique mechanism that involves a reversible change in the coordination environment of the metal centre. These coordination changes are mediated throughout the MOF by rotational mobility about the biaryl bond of the ligand.Tony D. Keene, Damien Rankine, Jack D. Evans, Peter D. Southon, Cameron J.

Introduction: The Internal Energy Market:Redefining Objectives
No full textAfter introducing sweeping EU legislation to establish a single market in energy, the EU has struggled to take the necessary steps to complete this process. By examining reports and other published documentation from a wide variety of bodies such as the EU Audit Committee and the various regulatory associations, this article identifies several reasons behind this failure. The most significant of these is the conflict between the single market project and the project to transition the EU to a low carbon economy status. It concludes that genuine completion is now highly improbable
The Concept of Genius in D. A. Granin’s Work (Based on the Novel “Evenings with Peter the Great”)
No full textThe article deals with D. A. Granin’s concept of history as presented in the novel “Evenings with Peter the Great”. The author of the novel argues that historical process is driven and streamlined by people endowed with rare gifts and deep urge to create such as the first Russian emperor Peter the Great
