The Kamthi Formation, in the intracratonic Pranhita-Godavari Gondwana rift basin, bore signatures of climate change from a warm humid climate in Late Permian to hot arid during the Early Triassic. Sedimentation took place mainly under fluvial conditi

Merocyanine dyes that exhibit antithetic cyanine-like behaviour and giant first-order hyperpolarisability (?) values have been designed. These cyanine-type dyes open up an intriguing route towards molecular-based electro-optic materials as well as ne

It is widely believed that atmospheric oxygen saturation rose from −5 present atmospheric level (PAL) in the Archean to >10 −2 PAL at the Great Oxidation Event (GOE) at ca. 2.4 Ga, but it is unclear if any earlier oxygenation events occurred. Her
