The use of porous materials to store natural gas in vehicles requires large amounts of methane per unit of volume. Here we report the synthesis, crystal structure and methane adsorption properties of two new aluminum metal-organic frameworks, MOF-519 and MOF-520. Both materials exhibit permanent porosity and high methane volumetric storage capacity: MOF-519 has a volumetric capacity of 200 and ...

Materials and Methods: Seventy-six patients who received two or four interforaminal implants were assigned to one of three different bar designs and subsequently to different prosthesis supporting systems. Forty-nine patients received implants and a mucosa-supported implantretained overdenture (OD) with an ovoid bar (two implants; design 1) or multiple ovoid bars (four implants; design 2). Twen...

DOMINO, E. F. AND M. P. LUTZ. Tolerance to the effects of daily nicotine on rat bar pressing behavior for water reinforcement. PHARMAC, BIOCHEM. BEHAV. 1(4) 445-448, 1973.-The effects of daily nicotine tartrate given IP in a dose of 0.25 mg/kg twice a day for 15 days was studied on bar pressing behavior for water reinforcement in the rat. A modified FR t 5 schedule was used. Nicotine injections...

Recent observations on structural properties of the Large Magellanic Cloud (LMC) based on the Deep Near-Infrared Southern Sky Survey (DENIS) and Two Micron All-Sky Survey (2MASS) have revealed that the LMC has an off-center bar even in the older stellar populations. Previous dynamical models including tidal interaction between the LMC, the Small Magellanic Cloud (SMC), and the Galaxy, however, ...

Isolated muscle fibers from the motor legs of the crab Trichodactilus dilocarcinus were submitted to strong hyperpolarizing currents of varied intensities which produced tension during the current pulse. Threshold for tension was obtained with intensities of about 0.2 x 10(-5) A, changing E(m) to ca. -150 mV (starting from a resting potential ofca. -80 mV). At the closure of the anodic square p...

We present evidence that the peculiar interacting starburst galaxy NGC 2782 (Arp 215) harbors a gas-rich nuclear stellar bar feeding an M82-class powerful central starburst, from a study based on high resolution interferometric CO (J=1->0) data, optical BVR and Hα observations, along with available NIR images, a 5 GHz radio continuum map, and archival HST images. Morphological and kinematic dat...

Statistics of mitochondrial association with spindle poles in wild type and mto1∆ (Figures 1D and 2B) Out of the 35 imaged wild-type cells, 18 cells showed constant mitochondrial association (red bar in Figure 1D), 6 showed at least one spindle pole free from mitochondria for at least 5 minutes (green bar in Figure 1D), 6 displayed temporary mitochondrial detachment (not included in the compari...

Dynamic membrane remodeling during intracellular trafficking is controlled by the intricate interplay between lipids and proteins. BAR domains are modules that participate in endocytic processes by binding and deforming the lipid bilayer. Sorting nexin 9 (SNX9), which functions in clathrin-mediated endocytosis, contains a BAR domain, however, the properties of this domain are not well understoo...

Microstructure evolution of commercial pure titanium is investigated by interrupted in situ electron backscatter diffraction (EBSD) measurement during tensile deformation along transverse direction at room temperature. After 24 pct elongation, the split basal texture initial material weakened and rotated around 90 deg normal (ND). $${{11}\bar{2}{{2}}}$$ - $${{10}\bar{1}{{2}}}$$ double twin main...

The reactions of the cationic transition metal acetonitrile complexes [M(CH3CN)n]m+ (m = 2: M = Fe, Co and m = 1: M = Cu, Ag) with GaCp* were investigated. The reaction of [Fe(CH3CN)6][BArF]2 (BAr(F) = [B{C6H3(CF3)2}4) with GaCp* leads to [Cp*Fe(GaCp*)3][BAr(F)] (1) via a redox neutral Cp* transfer and [Ga2Cp*][BAr(F)] as a by-product while the formation of [Cp*Co(GaCp*)3][BAr(F)]2 (2) from [Co...
