Tetraphenyladamantane-based porous poly(Schiff base)s with BET surface area (>1000 m(2) g(-1)), CO2 uptake (15 wt%, 273 K/1 bar) and H2 uptake (1.26 wt%, 77 K/1 bar) were synthesized. The structure-directing effect of isomers of phenyl diamines on building porous architecture was investigated.

Eukaryotic cells are defined by extensive intracellular compartmentalization, which requires dynamic membrane remodeling. FER/Cip4 homology-Bin/amphiphysin/Rvs (F-BAR) domain family proteins form crescent-shaped dimers, which can bend membranes into buds and tubules of defined geometry and lipid composition. However, these proteins exhibit an unexplained wide diversity of membrane-deforming act...

We report the structure, performance and large-area fabrication of a thin plasmonic infrared absorber, termed "bar-shaped disk-coupled dots-on-pillar antenna-array" (bar-D2PA). The bar-D2PAs, which are simple to fabricate, demonstrate the following, experimentally: (i) a different light-absorption resonance for each polarization with the resonance peak tunable by the bar-to-backplane gap and th...

A remarkable structure is observed in the innermost regions of the barred galaxy NGC 1415 : a small stellar bar, bright circumnuclear ionized gas seen in Hα, two bright ionized gas sources, seen in Hα, just beyond the ends of the small bar and a boxy distribution of optical continuum. We have developed a mass distribution model consisting in a disk, a bulge, and a bar to approximate the observe...

In this paper, a piezoelectrically actuated four-bar mechanism with two flexible links is proposed to be used in a micromechanical flying insect robot wing thorax for stroke amplification. PZT-5H and PZN-PT based unimorph actuators are utilized at the input link of the four-bar for a compact and light weight thorax transmission mechanism. The kinematics and dynamics of the proposed wing structu...

For decades, the grand-design SAB spiral galaxy NGC 5248 has been postulated to host a short bar of semi-major axis 22 (1.6 kpc). From dynamical and morphological arguments, we argue, however, that its spiral structure is being driven by a large-scale bar whose corotation radius lies at ∼ 115 (8.6 kpc). Our estimate is based partially on a deep R-band image which reveals that the feature previo...

ABSTRACT Stellar bars and spiral arms coexist co-evolve in most disc galaxies the local Universe. However, physical nature of this interaction remains a matter debate. In work, we present set numerical simulations based on isolated galactic models aimed to explore how bar properties affect induced structure. We cover large combination properties, including length, axial ratio, mass, rotation ra...
