Enantioselective construction of indanones from cyclobutanols using a rhodium-catalyzed C-C/C-H/C-C bond activation process

Enantioselective rhodium(I)-catalyzed reactions of tert-cyclobutanols, e.g. I, lead to indanones with quaternary stereogenic centers, e.g. II, via consecutive C-C/C-H/C-C bond activations. ...

Effects of glass additions on the microstructure and dielectric properties of barium strontium titanate (BST) ceramics

Alexander Tagantsev

Commercial glass frits (lead borosilicate glasses) were employed as the sintering aids to reduce the sintering temperatures of BST ceramics. The effects of the glass content and the sintering temperature on the microstructures, dielectric properties and tu ...

Improvement of elevated temperature mechanical properties of Cu–Ni–Sn–Pb alloys

Andreas Mortensen, Vincent Laporte, Doris Empl

Cu-Ni-Sn alloys with Pb additions exhibit high mechanical strength at room temperature coupled with good machinability but experience a significant ductility loss above the melting point of lead. We explore here the influence of minor additions of Al, Mn, ...

Alterations of the 5 ' Untranslated Region of SLC16A12 Lead to Age-Related Cataract

PURPOSE. Knowledge of genetic factors predisposing to age-related cataract is very limited. The aim of this study was to identify DNA sequences that either lead to or predispose for this disease. ...

Lead-free low-firing thick-film resistors based on bismuth glasses and ruthenium oxide

Peter Ryser, Claudio Grimaldi, Thomas Maeder, Caroline Jacq

Recent developments in thick-film technology have seen the widespread introduction of lead- free alternative to traditional conductive, dielectric and overglaze compositions. Resistors, however, have lagged behind this trend, as developing balanced and wel ...

Atomic structure of the two intermediate phase glasses SiSe4 and GeSe4

Alfredo Pasquarello

The microscopic origin of the intermediate phase in two prototypical covalently bonded A(x)B(1-x) network glass forming systems, where A=Ge or Si, B=Se, and 0

Comment on 'An analytic solution of capillary rise restrained by gravity' by N. Fries and M. Dreyer

David Andrew Barry, Laurin Wissmeier

The porous medium model of Green and Ampt, describing flow in porous media, appeared earlier than the capillary model of Washburn, although both lead to the mathematically identical models. The model of Green and Ampt is related to the Washburn model by an ...

Role Recognition for Meeting Participants: an Approach Based on Lexical Information and Social Network Analysis

Sarah Favre, Alessandro Vinciarelli, Nikhil Garg

This paper presents experiments on the automatic recognition of roles in meetings. The proposed approach combines two sources of information: the lexical choices made by people playing different roles on one hand, and the Social Networks describing the int ...
