Fused-pentagons results in an increase of local steric strain according to the isolated pentagon rule (IPR), and for all reported non-IPR clusterfullerenes multiple (two or three) metals are required to stabilize the strained fused-pentagons, making it difficult to access the single-atom properties. Herein, we report the syntheses and isolations of novel non-IPR mononuclear clusterfullerenes MN...

In this study, the influence of fullerene junction on the chemical features of 16 different drugs including Captopril, Clonidine, Methyldopa, Naphazoline, Oxymetazoline, Tetrahydrozoline, Xylometazoline, Tolazoline, Clemastine, Procyclidine, Tyramine, Nicotine, Dextroamphetamine, Fluoxetine, Metoprolol and Enalapril was investigated computationally. For this purpose, the mentioned drugs were pl...

A fullerene graph is a planar cubic graph whose all faces are pentagonal and hexagonal. The structure of cyclic edge-cuts of fullerene graphs of sizes up to 6 is known. In the paper we study cyclic 7-edge connectivity of fullerene graphs, distinguishing between degenerated and non-degenerated cyclic edge-cuts, regarding the arrangement of the 12 pentagons. We prove that if there exists a non-de...

Highly unsaturated mono(N-heterocyclic carbene) Ir(iii) systems have been targeted via ligand abstraction protocols. Hydrogenation of Ir(IPr)(cod)Cl (1a) leads to the formation of the highly reactive (fluxional) trimer [Ir(IPr)(H)(2)Cl](3), while the related IMes system undergoes further C-H bond activation. Chloride abstraction from 1a prior to hydrogenation allows access to sources of the 12-...

The enhancement of intellectual property rights (IPR) under the TRIPs agreement has to some degree been paralleled by an expansion of the literature on the optimal forms and roles of IPR systems. Economists have long concerned themselves (albeit with limited success) with such matters as optimal patent scope and duration. Public sector scientists have been particularly concerned with the effect...

The linear, two-coordinate and isostructural heteroleptic [M(IPr){N(SiMe3)2}] (IPr = 1,3-bis(diisopropylphenyl)-imidazol-2-ylidene), formally MI complexes (M = Co, 3; Fe, 4) were obtained by the reduction of [M(IPr)Cl{N(SiMe3)2}] with KC8, or [Co(IPr){N(SiMe3)2}2] with mes*PH2, mes* = 2,4,6-tBu3C6H2. The magnetism of 3 and 4 implies CoII and FeII centres coupled to one ligand-delocalized electr...

Intellectual property rights (IPR) of computer software is the right to assign the software to its creator, not limited to time and space, and non-transferable. Proving IPR of the creators of computer software requires a rigorous review of the ways in which these rights may be violated. The present study was conducted by comparing two populations in Iran with the aim of identifying the level of...

This paper aims at overcoming several shortcomings of previous empirical studies on the relationship between IPR protection and FD!. First of all, we use sectorally disaggregated FDI data for a large sampie of host countries. Second, we address the proposition that stronger IPR protection raises not only the quantity but also the quality of FD!. Third, we check to which extent the relationship ...

INTERPROXIMAL REDUCTION IN CONJUNCTION WITH PLASTIC ALIGNER THERAPY: A RETROSPECTIVE PILOT STUDY Adam Chorak, DDS August 1, 2011 Background: For more than 10 years, Invisalign has been a treatment alternative to traditional bands and brackets for the treatment of malocclusion. In order to relieve crowding in the dentition, interproximal reduction (IPR) or stripping is often required. Invisalign...

Small Problem We read with great interest the article by van Rooij et al regarding the endovascular treatment of very small aneurysms ( 3 mm). The conclusion of the study that coiling of very small aneurysms is more frequently complicated by intraprocedural rupture (IPR) is consistent with previous series and is technically understandable. However, conflicting data do exist from the 1010 patien...
