Metal-organic framework-5 (MOF-5) of composition Zn4O(BDC)3 (BDC = 1,4-benzenedicarboxylate) with a cubic three-dimensional extended porous structure adsorbed hydrogen up to 4.5 weight percent (17.2 hydrogen molecules per formula unit) at 78 kelvin and 1.0 weight percent at room temperature and pressure of 20 bar. Inelastic neutron scattering spectroscopy of the rotational transitions of the ad...

The coordination replication technique is employed for the direct conversion of a macroand mesoporous Cu(OH)2–polyacrylamide composite to three-dimensional superstructures consisting of the flexible porous coordination polymers, Cu2(bdc)2(MeOH)2 and Cu2(bdc)2(bpy) (bdc 2 1⁄4 1,4-benzenedicarboxylate, bpy 1⁄4 4,40-bipyridine). Detailed characterization of the replicated systems reveals that the ...

A bidirectional converter (BDC) is required in areas where generated energy is stored. Some of the application areas are uninterruptible power system, transportation,, flywheel energy storage systems, etc. Bidirectional flow of power using buck mode and boost mode along with efficiency and high power density is important need of such systems. This report proposes a new topology of BDC with the ...

The asymmetric unit of the title coordination polymer, {[La(2)(C(8)H(4)O(4))(3)(H(2)O)]·0.5H(2)O}(n), contains two independent La(III) atoms, one of which is surrounded by eight carboxyl-ate-O atoms from six benzene-1,2-dicarboxyl-ate (BDC) anions in a bicapped trigonal-prismatic geometry. The other La(III) atom is nine-coordinated in a tricapped trigonal-prismatic geometry, formed by eight car...

A new rare-earth borate LiRb2LaB2O6 (LB-1) has been synthesized using a high-temperature solution method. Interestingly, it shares its topological structure with the famous porous material MOF-5, which is formed from Zn4O(BDC)3 (BDC = 1,4-benzenedicarboxylate). The nodes [OZn4] and organic linkers [BDC] of MOF-5 are carefully substituted with La3+ rare-earth cations and the inorganic linkers [B...

Conventional dual active bridge (DAB) converters based on the non-resonant circuit topology have sever limitation of soft switching under light load conditions without complex multi-pulse modulations such as or triple phase shift. To address this technical problem, paper explores a symmetrical series-resonant bidirectional dc-dc converter (SSR-BDC). The SSR-BDC features variable frequency shift...

events (Bechara et al., 1997; Damasio et al., 1990), we predicted that patients with VMPC damage would fail to perceive the emotional significance of harmful intentions (e.g., unobservable mental states), and therefore deliver abnormal moral judgments in the case that judgments depend on emotional responses to such abstract representational content. We predicted that, as a direct result, VMPC p...

Hyperbilirubinemia (HB) is sometimes encountered following bile-duct cannulation in rats. It possibly originates from the reduced functioning of multidrug resistance-associated protein 2 (Mrp2) and subsequent adaptive alterations in the expression of Mrp3 and the organic anion transporting polypeptides (Oatps). Our aim was to clarify the importance of excluding bile-duct-cannulated (BDC) rats w...

Bile duct cysts (BDC) are rare congenital anomalies of the biliary tree that are characterized by cystic dilatation of the extrahepatic and/or intrahepatic bile ducts. Presence of an anomalous bilio-pancreatic junction allowing pancreatic juice to reflux into the biliary tree is the most widely aetiopathogenic concept currently accepted. BDC are associated with biliary stasis and lithiasis, and...

I n 1967, Bachman described a ‘‘hereditary peripheral dysostosis’’ which affected a mother and her two children. What was later considered as multiple epiphyseal dysplasia combined with phalangeal cone shaped epiphyses was renamed angel shaped phalangoepiphyseal dysplasia (ASPED) and considered as a genetic bone marker. ASPED represents a further variety of multiple epiphyseal dysplasia and is ...
