Cage Compounds and Redox Synthesis
Intermetallic clathrates were discovered in the 1950s when the basic relations of alkali metals and group 14 elements were investigated [1, 2]. After the structural elucidation of Na8Si46 and NaxSi136 [3] the research field spread continuously, and representatives comprising Na, K, Rb and Cs were obtained. The only exception was the Li-containing clathrate and it was concluded that Li atoms are...
متن کاملCholate-Based Synthesis of Size-Tunable Cage Compounds
We describe cholate-based cage amphiphiles with a unique architecture that combines elements of structural rigidity and flexibility. The cage compounds are built by extending and bridging three polar chains underneath the concave steroid rings of cholate and capping with another rigid, symmetrically trifunctionalized cyanuric acid moiety. The connecting chains are varied to include, for instanc...
متن کاملSynthesis of novel acetal thia-cage compounds.
The synthesis of novel acetal thia-cage compounds has been accomplished by the direct substitution for the oxygen atom by the sulfur atom in the reaction of the acetal groups of oxa-cages with Lawesson reagent (LR). Reaction of the tetraoxa-cage compound 2 with LR in dichloromethane at 25 degrees C sequentially gave the monothia-, dithia-, trithia-, and tetrathia-cage compounds 3, 6, 7, and 9. ...
متن کاملmortality forecasting based on lee-carter model
over the past decades a number of approaches have been applied for forecasting mortality. in 1992, a new method for long-run forecast of the level and age pattern of mortality was published by lee and carter. this method was welcomed by many authors so it was extended through a wider class of generalized, parametric and nonlinear model. this model represents one of the most influential recent d...
15 صفحه اولCage-Based Tree Deformation
Tree models are broadly used in multimedia applications, but it is a challenge task to deform trees with plenty of branches. We propose a novel method to deform the tree model interactively using cages based on trees' property, and we design a framework to control the hierarchy deformation of trees. The bounding box of the trunk is used as the global control cage, while the bounding boxes of br...
