Nitrogen Hydrate Cage Occupancy and Bulk Modulus Inferred from Density Functional Theory-Derived Cell Parameters
Gas clathrate hydrate solid materials, ubiquitous in nature as found either on the ocean floor, permafrost on the Earth, or in extraterrestrial planets and comets, are also technologically relevant, for example, in energy storage or carbon dioxide sequestration. Nitrogen hydrate, in particular, is ...
Diversity-oriented Synthesis of Spiropyrrolo[1, 2-a]isoquinoline Derivatives via Diastereoselective and Regiodivergent Three-component 1,3-Dipolar Cycloaddition Reactions: In vitro and in vivo Evaluation of the Antidiabetic Activity of Rhodanine Analogues
An efficient diastereoselective route is developed to get access to novel spiropyrrolo[1,2-a]isoquinoline-oxindole skeletons by a one-potthree-component [3 + 2] cycloaddition reaction of (Z)-5-arylidene-1,3-thiazolidine-2,4-diones, isatin derivatives, and 1,2,3,4-tetrahydroisoquinoline (THIQ). ...
Pollen analysis - Avenches (Suisse, Vaud), Boat n°3, Roman museum
Two moss samples taken from a Roman boat. This moss ("Neckera crispa") was used to caulk the gaps between the construction elements of this boat. The pollens preserved in these mosses are dominated by beech, fir and spruce so these mosses were probably collected on the limestone sides of the Jura ...
Pollen analysis - Steinhausen (Suisse, Zug), Chalet 1700 + ZCS
Five palynological samples from moss used to fill the gaps between the construction elements of an alpine chalet. Dendrochronological date: between 1608 and 1700 AD.
Reactivity of CuI and CuBr toward Dialkyl Sulfides RSR: From Discrete Molecular Cu4I4S4 and Cu8I8S6 Clusters to Luminescent Copper(I) Coordination Polymers
The CuX salts (X = I, Br) react with SR2 to form molecular clusters of the types [(R2S)4(Cu4I4)] and [(R2S)6(Cu8I8)] or to give 1D polymers and 2D metal−organic frameworks. The cluster nuclearity and connectivity as well as the dimensionality of these compounds depend on the steric demand of SR2, ...
