Reactions of amines with ozone and chlorine: Two novel oxidative methods to evaluate the N-DBP formation potential from dissolved organic nitrogen

Urs von Gunten, Karim-Alexandre Essaied, Lucy Victoria Brown

The composition of oxidant-reactive dissolved organic nitrogen (DON) is poorly characterized, although its ozonation is likely to form a great variety of disinfection by-products containing a nitrogen-oxygen bond (NDBPs). In this study, two chemical oxidat ...

Explosive fragmentation of Prince Rupert's drops leads to well-defined fragment sizes

Jean-François Molinari

Anyone who has ever broken a dish or a glass knows that the resulting fragments range from roughly the size of the object all the way down to indiscernibly small pieces: typical fragment size distributions of broken brittle materials follow a power law, an ...

Impact of quantum-chemical metrics on the machine learning prediction of electron density

Ksenia Briling, Alberto Fabrizio

Machine learning (ML) algorithms have undergone an explosive development impacting every aspect of computational chemistry. To obtain reliable predictions, one needs to maintain a proper balance between the black-box nature of ML frameworks and the physics ...

Reactive surface organometallic complexes observed using dynamic nuclear polarization surface enhanced NMR spectroscopy

David Lyndon Emsley, Jasmine Viger-Gravel, David Benjamin Roger Antoine Gajan

Dynamic Nuclear Polarization Surface Enhanced NMR Spectroscopy (DNP SENS) is an emerging technique that allows access to high-sensitivity NMR spectra from surfaces. However, DNP SENS usually requires the use of radicals as an exogenous source of polarizati ...

Royal Soc Chemistry2017

Industrial chemical processes may involve thermal risks as most of the reactions performed are exothermic, the chemicals used are often thermally unstable, and the operating conditions are set to induce high conversion and throughput. Besides the reactive ...

Mechanical and microstructural characteristics of Ti6Al4V/AA2519 and Ti6Al4V/AA1050/AA2519 laminates manufactured by explosive welding

Marco Cantoni

The aim of the work was to produce laminated structures consisting of Ti-6Al-4V alloy and AA2519 plates and to investigate their microstructure and mechanical properties with anemphasis on the role of an additional AA1050 interlayer. Explosive welding was ...

High Power Electromagnetics Applied to Humanitarian Demining in Colombia

Nicolas Mora Parra

This paper summarizes the main findings of a long-term research to explore the use of high power electromagnetics in humanitarian demining. A neutralization method based on remote detonation of electrically-activated improvised explosive devices (IED) was ...

Sample Enrichment for Bioanalytical Assessment of Disinfected Drinking Water: Concentrating the Polar, the Volatiles, and the Unknowns

Urs von Gunten

Enrichment methods used in sample preparation for the bioanalytical assessment of disinfected drinking water result in the loss of volatile and hydrophilic disinfection byproducts (DBPs) and hence likely tend to underestimate biological effects. We develop ...
