A Crystallographic Story of Snakes and Ladders: Encapsulated Water Polymers and Rigid Metal Complexes Based on Mono-N-substituted Carboxylate 4,4'-Bipyridine

Paul Joseph Dyson, Rosario Scopelliti, Zhaofu Fei, Wee Han Ang, Andrew Douglas Phillips

A new zwitterionic bidentate ligand was synthesized incorporating a 4,4'-bipyridine core with a carboxylate group as a single building block, specifically designed for the rational construction of supramol. structures (metal-org. frameworks) that are capab ...

Sampling Urban Mobility through On-line Repositories of GPS Tracks

We analyze urban mobility by relying on the short-term mobility traces gathered from a publicly available web-based repository of GPS tracks - the Nokia Sports Tracker service. All mobility traces are obtained from a set of kml files. We show how the data ...

On the parameterization of rigid base and basepair models of DNA from molecular dynamics simulations

John Maddocks, Leesa Maree Heffler

A method is described to extract a complete set of sequence-dependent material parameters for rigid base and basepair models of DNA in solution from atomistic molecular dynamics simulations. The method is properly consistent with equilibrium statistical me ...

Water Influence on Mechanical Behaviour of Pavements: Constitutive Modelling

Lyesse Laloui

This chapter deals with the effects of water on the mechanical behaviour of pavements. The analysis is based on constitutive considerations. Constitutive models devoted to both routine and advanced pavement analysis and design are introduced and both the r ...

Switch peptide via Staudinger reaction

Hilal Lashuel

A new transformation based on the Staudinger reaction is described, and its application in the design of a novel switch element to control peptide folding is demonstrated. We found that the azide switch is activated rapidly in water to promote acyl transfe ...

Optical Kerr effect studies of the dynamics of confined water

Majed Chergui, Frank van Mourik, Erwin Portuondo Campa

Time resolved optical Kerr effect measurements have been used to det. the orientational dynamics of water in the pores of ZrO2 nanostructured films. We demonstrate that local heating effects can safely be ignored and present our results which are manifestl ...

Water sector evolution scenarios: the case of Europe

Matthias Finger, Patricia Alves Luis Manso

The purpose of this article is to identify possible scenarios for the evolution of the European water supply and sanitation sectors (WSS) in the next 15 years, on the basis of empirical knowledge of its dynamics. These are: tendered market, tendered market ...

Influences of the unsaturated, saturated, and riparian zones on the transport of nitrate near the Merced River, California, USA

Janet Gordon Hering

Transport and transformation of nitrate was evaluated along a 1-km groundwater transect from an almond orchard to the Merced River, California, USA, within an irrigated agricultural setting. As indicated by measurements of pore-water nitrate and modeling u ...

Enhanced cyanine solar cell performance upon oxygen doping

Jacques-Edouard Moser, Frank Nüesch, Roland Hany, Bin Fan

The effect of exposing cyanine–fullerene C60 bilayer solar cells to ambient atmosphere is investigated. For exposure times of a few hours and concomitant light soaking, the device performance experiences a drastic power efficiency increase going from 0.14% ...

Transport properties of water and glycol in an ultra high performance fiber reinforced concrete (UHPFRC) under high tensile deformation

Eugen Brühwiler, Emmanuel Denarié

Ultra High Performance Fiber Reinforced Concretes (UHPFRC) present outstanding mechanical properties and a very low permeability. Those characteristics make them very attractive for the rehabilitation of existing structures and the conception of new struct ...
