Unwilling U-U bonding in U2@C80: cage-driven metal-metal bonds in di-uranium fullerenes.
Endohedral actinide fullerenes are rare and a little is known about their molecular properties. Here we characterize the U2@C80 system, which was recently detected experimentally by means of mass spectrometry (Akiyama et al., JACS, 2001, 123, 181). Theoretical calculations predict a stable endohedral system, (7)U2@C80, derived from the C80:7 IPR fullerene cage, with six unpaired electrons. Bond...
متن کاملOn the U-WPF Acts over Monoids
Valdis Laan in [5] introduced an extension of strong flatness which is called weak pullback flatness. In this paper we introduce a new property of acts over monoids, called U-WPF which is an extension of weak pullback flatness and give a classification of monoids by this property of their acts and also a classification of monoids when this property of acts implies others. We also show that regu...
متن کاملRealization of u-Contents: u-Realism, u-Mobility and u-Intelligence
—Recently the developments of Ubiquitous Computing and Augmented Reality technologies have made many changes on the existing applications. However, the contents used in the applications have been not revised conceptually. Thus, an expansive representation of the contents is required to adapt resources to new computing environments, and to reflect new emerging features such as realism, mobility ...
متن کاملOn constacyclic codes over Z4[u]/〈u2-1〉 and their Gray images
We first define a new Gray map from R = Z4+uZ4 to Z 2 4, where u 2 = 1 and study (1 + 2u)-constacyclic codes over R. Also of interest are some properties of (1 + 2u)constacyclic codes over R. Considering their Z4 images, we prove that the Gray images of (1+2u)-constacyclic codes of length n over R are cyclic codes of length 2n over Z4. In many cases the latter codes have better parameters than ...
متن کاملOn the property $U$-($G$-$PWP$) of acts
In this paper first of all we introduce Property $U$-($G$-$PWP$) of acts, which is an extension of Condition $(G$-$PWP)$ and give some general properties. Then we give a characterization of monoids when this property of acts implies some others. Also we show that the strong (faithfulness, $P$-cyclicity) and ($P$-)regularity of acts imply the property $U$-($G$-$PWP$). Finally, we give a necessar...
