CO Cleavage and CO2 Functionalization under Mild Conditions by a Multimetallic CsU2 Nitride Complex

Rosario Scopelliti, Marinella Mazzanti, Lucile Sylvie Danielle Chatelain, Marta Falcone

Novel efficient chemical processes involving cheap and widely accessible carbon dioxide or carbon monoxide under mild conditions for the production of valuable chemical products are highly desirable in the current energetic context. Uranium nitride materia ...

Formation and reactivity of inorganic and organic chloramines and bromamines during oxidative water treatment

Urs von Gunten, Jeremy Samuel Arey, Daniela Trogolo, Michèle Bernadette Heeb

The formation and further reactions of halamines during oxidative water treatment can be relevant for water quality. In this study, we investigated the formation and reactivity of several inorganic and organic halamines (monochloramine, N-chloromethylamine ...

Bonded sleeve connections for joining tubular GFRP beam to steel member: Numerical investigation with experimental validation

Zhujing Zhang, Yu Bai, Chao Wu

This paper investigates an innovative bonded sleeve connection for joining tubular GFRP and steel members. Experimental results focused on mechanical responses of beam-to-column specimens using bonded sleeve connections and conventional steel angle connect ...

Bond behaviour of straight, hooked, U-shaped and headed bars in cracked concrete

Aurelio Muttoni, Miguel Fernández Ruiz, Duarte Miguel Viúla Faria, Fabio Brantschen

Most classic investigations on bonding properties in reinforced concrete have been performed on the basis of pull-out tests, where a reinforcement bar is pulled out from an uncracked concrete cylinder, prism or cube. In these tests, the bond is governed by ...

On the statistical physics of chains and rods, with application to multi-scale sequence-dependent DNA modelling

Alexandre Emmanuel Grandchamp

The complex mechanisms involved in cellular processes have been increasingly understood this past century and the central role of the DNA molecule has been recognized. The base pair sequence along a DNA fragment is observed not only to encode the genomic i ...

New evidence for Cu-decorated binary-oxides mediating bacterial inactivation/mineralization in aerobic media

César Pulgarin, Juan Kiwi, Michaël Bensimon, Sami Rtimi

Binary oxide semiconductors TiO2-ZrO2 and Cu-decorated TiO2-ZrO2 (TiO2-ZrO2-Cu) uniform films were sputtered on polyester (PES). These films were irradiated under low intensity solar simulated light and led to bacterial inactivation in aerobic and anaerobi ...

Competing Interactions in the Self-Assembly of NC-Ph-3-CN Molecules on Cu(111)

Harald Brune, Marina Pivetta, Giulia Elisabetta Pacchioni

We report on low-temperature scanning tunneling microscopy and spectroscopy measurements on NC-Ph-3-CN molecules adsorbed at 300 K on a Cu(111) surface. Upon cooling, the molecules form chain and honeycomb structures, incorporating Cu adatoms supplied by t ...

Physical pressure and chemical expansion effects on the skyrmion phase in Cu2OSeO3

Helmuth Berger

The effects of external (hydrostatic) compression and internal (chemical) expansion on the skyrmion phase have been investigated in Cu2OSeO3 single crystal and Cu2OSe1-xTexO3 (0

Probing the electronic and geometric structure of ferric and ferrous myoglobins in physiological solutions by Fe K-edge absorption spectroscopy

Majed Chergui, Ursula Röthlisberger, Ivano Tavernelli, Thomas James Penfold, Marco Eli Reinhard, Frederico Alves Lima

We present an iron K-edge X-ray absorption study of carboxymyoglobin (MbCO), nitrosylmyoglobin (MbNO), oxymyoglobin (MbO(2)), cyanomyoglobin (MbCN), aquomet myoglobin (metMb) and unligated myoglobin (deoxyMb) in physiological media. The analysis of the XAN ...

Tension Chord Model Modification for Uniaxial Unloading and Reloading in Elastic and Plastic States

Thomas Keller, Robert Koppitz

The bond properties between concrete and steel reinforcement influence structural stiffness and deformation behavior as a result of tension stiffening. In specific cases, the load-bearing capacity of engineering structures depends on the deformation behavi ...
