This facile hydrogenation strategy is based on room temperature H2 dissociation into [H] on Pd, providing a general methodology for transitional metal oxide hydrogenation under ordinary conditions for advanced photocatalysis systems.

MYRICA RUBRA Sieb. et Zucc. leaves are commonly used in folk medicine to treat inflammatory disorders in China. Present studies on the anti-inflammatory effect of myricetin from MYRICA RUBRA Sieb. et Zucc. leaves was evaluated with various IN VIVO models of both acute and chronic inflammations such as xylene-induced ear edema, acetic acid-induced vascular permeability, carrageenan-induced paw edema, leukocyte migration assay, and cotton pellet granuloma models. Myricetin showed a significant inhibition on ear edema and hind paw edema caused by xylene and carrageenan, respectively. Furthermore, it also inhibited the increase in capillary permeability induced by the production of acetic acid in the human body. Myricetin significantly decreased the serum levels of MDA and, in turn, increased the serum levels of SOD in the carrageenan-induced paw edema model. Concurrently, myricetin also significantly decreased leukocyte count. During chronic inflammation, myricetin inhibited the formation of granuloma tissue. These results, collectively, demonstrate that myricetin possesses a potent anti-inflammatory function on acute and chronic inflammation. Its anti-inflammatory mechanisms are probably associated with the inhibition of antioxidant activity. These results also support the claims of traditional Chinese medicine practitioners about the use of MYRICA RUBRA Sieb. et Zucc. leaves in the treatment of inflammatory diseases.

A significant overpotential necessary for the electrochemical oxygen evolution reaction (OER) is one of the most serious disadvantages in water electrolysis, which, on the contrary, gives the probability to electrochemically produce ozone alternative to the common corona discharge. To effectively suppress the competitive OER and improve gaseous ozone escaping, here we present a capillary effect-enabled electrolysis strategy by employing an unusual partial-submersed mode of anode composed of a β-PbO cuboids-loaded bulk porous Pb, and realize a much enhanced electrocatalytic gaseous ozone production in comparison to the cases of solid Pb counterpart and/or usual submersion operation. Detailed study reveals a capillary pressure-induced "molecular oxygen-locking effect" in the electrolyte fully filled in the porous structure of the electrode area above the electrolyte pool level, which unexpectedly leads to the production of unusual ·O intermediate. Distinctive from the traditional electrochemical ozone production (EOP) mechanism dependent on the essential reaction between the atomic oxygen and molecular oxygen, the ·O intermediate generation favors the EOP process in the special case where the capillary action is relevant for a porous bulk anode.
