High Pressure NMR Studies of Supercooled Viscous Fluids
… coupling parameter. It was shown for the cyclic carbonate system, 4-methyl-1,3-dioxolan-2-one, 4-chloro-1,3-dioxolan-2-one, and 4,5-dichloro-1,3-dioxolan-2-one, that the permanent dipole plays a important role in determining the rotational-translational coupling. Using constant reduced …

Reversibly Photo-Crosslinkable Polycarbonate-Based Polymersomes for Drug Encapsulation and Delivery
… from poly(ethylene glycol)-block-polycarbonate (PEG-PC) copolymers functionalized with pendant coumarin groups. Coumarin groups undergo photo-reversible dimerization when irradiated with specific ultraviolet wavelengths, so they can be used to prepare polymers with photo-responsive …

Cyclostratigraphy of Late Cambrian cyclic carbonates: An interbasinal field and modelling study, U.S.A.
An interbasinal study of Late Cambrian cyclic carbonate successions in the Appalachian and Cordilleran passive margins, the Texas cratonic embayment and the southern Oklahoma aulacogen has provided controls on the simultaneous development of peritidal to subtidal meter-scale cycles and the larger …

SOLID-SUPPORTED PORPHYRINS FOR CATALYSIS AND SENSING
… and aziridines to synthesize respectively cyclic carbonates and oxazolidinones. In order to enhance the catalytic activity without losing the eco-compatibility of the catalyst, hemin-derivatives were supported onto CC, which displays very good eco-friendly characteristics due to their …

Cracking Meldrum's Acid: Lowering the Temperature
… for their capacity to form ketenes through cyclic carbonate and cyclic thiocarbonate intermediates. The synthesised malonic acids were analysed through thermogravimetric analysis experiments. It was found that the two dialkynyl malonic acids decarboxylated readily and possessed a different …

FREE-BASE PORPHYRIN FOR CO2 ACTIVATION
… synthesis of very useful fine chemicals such as cyclic carbonates and oxazolidinones from a waste -as CO2- with a 100% of atom economy. However, carbon dioxide is a very stable molecule and an efficient catalytic species is needed to make the reaction proceeds by avoiding drastic conditions. Even …
