Two porous supramolecular isomeric frameworks show unique sorption properties, one with temperature dependent stepwise and hysteretic selective sorption of CO 2 while the other one shows gas uptake capacity for CO 2, N 2, H 2 and CH 4 at low temperature and selective sorption of CO 2 over N 2 around room temperature. © 2011 The Royal Society of Chemistry.

The role of a calcium-dependent and calmodulin (CaM)-stimulated protein kinase in abscisic acid (ABA)-induced antioxidant defense was determined in leaves of maize (Zea mays). In-gel kinase assays showed that treatments with ABA or H2O2 induced the activation of a 49-kDa protein kinase and a 52-kDa protein kinase significantly. Furthermore, we showed that the 52-kDa protein kinase has the characteristics of CaM-stimulating activity and is sensitive to calcium-CaM-dependent protein kinase II (CaMK II) inhibitor KN-93 or CaM antagonist W-7. Treatments with ABA or H2O2 not only induced the activation of the 52-kDa protein kinase, but also enhanced the total activities of the antioxidant enzymes, including catalase, ascorbate peroxidase, glutathione reductase, and superoxide dismutase. Such enhancements were blocked by pretreatment with a CaMK inhibitor and a reactive oxygen species (ROS) inhibitor or scavenger. Pretreatment with the CaMK inhibitor also substantially arrested the ABA-induced H2O2 production. Kinase activity enhancements induced by ABA were attenuated by pretreatment with an ROS inhibitor or scavenger. These results suggest that the 52-kDa CaMK is involved in ABA-induced antioxidant defense and that cross-talk between CaMK and H2O2 plays a pivotal role in ABA signaling. We infer that CaMK acts both upstream and downstream of H2O2, but mainly acts between ABA and H2O2 in ABA-induced antioxidant-defensive signaling. © The Author 2010. Source

A novel series of samples Sn1-xGaxP2O7 (x = 0.00, 0.01, 0.03, 0.06, 0.09, 0.12, 0.15) are synthesized by solid state reaction. XRD patterns indicate that the samples of x = 0.00 - 0.09 exhibit a single cubic phase structure, and the doping limit of Ga3+ in Sn1-xGaxP2O7 is x = 0.09. The protonic and oxide-ionic conduction in Sn1-xGaxP2O7 are investigated using some electrochemical methods at intermediate temperatures (323-523 K). It is found that the samples exhibit appreciable protonic conduction in hydrogen atmosphere, and a mixed conduction of oxide-ion and electron hole in dry oxygen-containing atmosphere. The highest conductivities are observed for the sample of x = 0.09 to be 4.6 × 10-2 S cm-1 in wet H2 and 2.9 × 10-2 S cm-1 in dry air at 448 K, respectively. The H2/air fuel cell using x = 0.09 as electrolyte (thickness: 1.45 mm) generates a maximum power density of 19.2 mW cm-2 at 423 K and 22.1 mW cm-2 at 448 K, respectively. © 2010 Elsevier B.V.

In order to elucidate the electronic structure of the hydrogen-bridge bond in B2H6 molecule, the formation process of B2H6 had been created by a hypothetical reaction of "B 2H 4 2- + 2H +", and the symmetry principles for reaction are applied in the process of creating new molecular orbitals through linear combination of the old orbitals. The orbital components of the hydrogen-bridge bond in B 2H 6 are obtained, and the electronic structure of the hydrogen-bridge bond is explained qualitatively. In addition, the idea that explains the structure of a molecule by creating a hypothetical reaction is proposed, which might make more application in other cases. © Springer Science+Business Media, LLC 2011.
