Oxybis(dimesitylborane) dichloromethane hemisolvate
The title compound, C36H44B2O·0.5CH2Cl2, contains an almost linear O—B—O linkage [177.23 (15)°] and approximately orthogonal [interplanar angles 89.49 (5) and 80.77 (4)°] trigonal planar B centers, consistent with the previously reported non-solvated structure [Cardinet al. (1983). J. Chem. Res. (S), p. 93]. Intermolecular C—H⋯π interactions exist between mesityl groups, with a C—H⋯centroid separation of 3.6535 (18) Å. The dichloromethane molecules lie on twofold rotation axes
Increasing your U.S. News and World Report graduate school rankings: a census of public affairs schools and their strategic communications efforts to create a tradition of distinction
Colleges and schools in today??s competitive marketplace must not only be
cognizant of student and faculty recruitment, but also of their positioning in rankings.
This thesis seeks to determine how the use of strategic communications can play a role
in increasing student applications, the quality of student applications and funding
resources; thereby, increasing their rank as determined by the U.S. News and World
Report. It is believed that an in-depth strategic communications plan committed to paper,
and resourced properly, can increase each of these areas. Specifically, this research
examined the top 50 ranked schools in public affairs to determine the relationship
between top ranked schools and their communications departments and each of their
uses of strategic communications as defined as the long-term planning, implementation
and research of the use of public relations, marketing, and advertising
Bis(μ-dimesitylborinato-κ2 O:O)bis[(2-methylpyridine-κN)lithium]
The title compound, [Li2(C18H22BO)2(C6H7N)2], is a lithium dimesitylboroxide dimer in which the lithium cation is also coordinated by one molecule of 2-methylpyridine. At the core of the structure is an Li2O2 four-membered ring. The structure is centrosymmetric with an inversion centre midway between two Li atoms. Intermolecular C—H⋯π interactions and π–π interactions between the 2-methylpyridine rings exist [centroid–centroid distance = 3.6312 (16) Å]
Diffusion doping of cobalt in rod-shape anatase TiO\u3csub\u3e2\u3c/sub\u3e nanocrystals leads to antiferromagnetism†
Cobalt(II) ions were adsorbed to the surface of rod-shape anatase TiO2 nanocrystals and subsequently heated to promote ion diffusion into the nanocrystal. After removal of any remaining surface bound cobalt, a sample consisting of strictly cobalt-doped TiO2 was obtained and characterized with powder Xray diffraction, transmission electron microscopy, UV-visible spectroscopy, fluorescence spectroscopy, X-ray photoelectron spectroscopy, SQUID magnetometry, and inductively-coupled plasma atomic emission spectroscopy. The nanocrystal morphology was unchanged in the process and no new crystal phases were detected. The concentration of cobalt in the doped samples linearly correlates with the initial loading of cobalt(II) ions on the nanocrystal surface. Thin films of the cobalt doped TiO2 nanocrystals were prepared on indium-tin oxide coated glass substrate, and the electrical conductivity increased with the concentration of doped cobalt. Magnetic measurements of the cobalt-doped TiO2 nanocrystals reveal paramagnetic behavior at room temperature, and antiferromagnetic interactions between Co ions at low temperatures. Antiferromagnetism is atypical for cobalt-doped TiO2 nanocrystals, and is proposed to arise from interstitial doping that may be favored by the diffusional doping mechanism
