The contents of unusual cone-shaped vessels (cornets) from the Chalcolithic of the southern Levant
Cornets are cone-shaped ceramic vessels, characteristic of the Chalcolithic period (ca. 4700–3700 BC) in Israel and Jordan. Their contents and use are unknown. Gas chromatography with flameExpand

Iron Age beehives at Tel Reḥov in the Jordan valley
Beehives were discovered in a densley built area in the Iron Age city of Reḥov (tenth-ninth century BC). They consisted of hollow clay cylinders, each with a little hole at one end (for the bee) andExpand

Oxidation of activated phenols by dioxygen catalysed by the H5PV2Mo10O40 heteropolyanion
Abstract The H 5 PV 2 Mo 10 O 40 heteropolyanion has been found to catalyse the highly selective aerobic oxidation of dialkylphenols to diphenoquinones and the oxidation of 2, 3, 5-trimethylphenol toExpand

New heterogeneous polyoxometalate based mesoporous catalysts for hydrogen peroxide mediated oxidation reactions.
Inorganic-organic hybrid mesoporous materials were prepared by cocrystallization of a "sandwich" type polyoxometalate, [ZnWZn2(H2O)2(ZnW9O34)2]12-, and branched tripodal organic polyammonium salts,Expand

Photoreduction of carbon dioxide to carbon monoxide with hydrogen catalyzed by a rhenium(I) phenanthroline-polyoxometalate hybrid complex.
A phenanthroline ligand decorated at the 5,6-position with a 15-crown-5 ether was used to prepare a metalorganic-polyoxometalate hybrid complex Re(I)(L)(CO)(3)CH(3)CN-MHPW(12)O(40) (L =Expand
