IABSE Symposium, Vancouver 2017: Engineering the Future.
Within the coming decade many ageing rockfall protection galleries in the Swiss Alps will require rehabilitation measures to ensure their durability. Before a gallery is rehabilitated, its current safety level needs to be assessed to decide whether s

In order to maintain approximately 1500 engineering structures, the road office of Grisons in Switzerland has to repair or replace between 30 and 50 structures each year. Timing and scope of interventions is mainly driven by the condition state of th

Tetrahedron: Asymmetry. 15:251-257
Asymmetric hydrogenation of the activated carbonyl group of 1,1,1-trifluoro-2,4-diketones was studied over Pt/Al 2 O 3 modified by various chiral 1,2-aminoalcohols and amines. The best chiral modifiers were cinchonidine and O -methyl-cinchonidine, wh

Enantioselective hydrogenation of acetophenone derivatives demonstrates the potential of the Pt–cinchona system in the synthesis of chiral alcohols that possess no functional group in the α-position to the CHOH group. Electron-withdrawing funct

The relation between the electronic structure of α-substituted ketones and their reactivity in the racemic and enantioselective platinum-catalyzed hydrogenation has been investigated using a combined theoretical and experimental approach. A correlat

Heterogeneous enantioselective hydrogenation of activated ketones in a fixed-bed reactor was achieved by continuous feeding of minute amounts of chiral modifier to the reactant stream. The potential of this concept is illustrated using the hydrogenat
Inversion of enantioselectivity in the platinum-catalyzed hydrogenation of substituted acetophenones

The enantioselective hydrogenation of ring-substituted acetophenones that possess no functional group in the α-position to the keto group represents the latest extension of the application range of the Pt–cinchona system. The influence of the type
