Synthesis of cyclic carbonates from diols and CO2 catalyzed by carbenes

Paul Joseph Dyson, Felix Daniel Bobbink, Martin Hulla, Shoubhik Das, Weronika Gruszka

The synthesis of cyclic carbonates from epoxides and CO2 is a well-established reaction, whereas the synthesis of cyclic carbonates from diols and CO2 is considerably more challenging, and few efficient catalysts are available. Here, we describe heterocycl ...

Carbon Dioxide Based N-Formylation of Amines Catalyzed by Fluoride and Hydroxide Anions

Paul Joseph Dyson, Felix Daniel Bobbink, Martin Hulla, Shoubhik Das

We described herein a simple approach for N-formylation with CO2 and hydrosilane reducing agents. Fluoride and hydroxide salts efficiently catalyzed the reaction, principally through activation of the hydrosilanes, which led to hydrosilane reactivities com ...

Evolution of the charge density wave superstructure in ZrTe3 under pressure

Corsin Battaglia, Helmuth Berger, Philipp Aebi

The material ZrTe3 is a well-known example of an incommensurate periodic lattice distortion (PLD) at low temperatures due to a charge density wave (CDW). Previous studies have found a sharp boundary as a function of pressure between CDW below 5 GPa and bul ...

CFHTLenS: weak lensing calibrated scaling relations for low-mass clusters of galaxies

Jean-Paul Richard Kneib

L(X)We present weak lensing and X-ray analysis of 12 low-mass clusters from the Canada-France-Hawaii Telescope Lensing Survey and XMM-CFHTLS surveys. We combine these systems with high-mass systems from Canadian Cluster Comparison Project and low-mass syst ...

Atmospheric Flow Development and Associated Changes in Turbulent Sensible Heat Flux over a Patchy Mountain Snow Cover

Michael Lehning

In this study, the small-scale boundary layer dynamics and the energy balance over a fractional snow cover are numerically investigated. The atmospheric boundary layer flows over a patchy snow cover were calculated with an atmospheric model (Advanced Regio ...

Influences of Dilute Organic Adsorbates on the Hydration of Low-Surface-Area Silicates

David Lyndon Emsley, Aaron James Rossini, Bradley Floyd Chmelka, David Benjamin Roger Antoine Gajan

Competitive adsorption of dilute quantities of certain organic molecules and water at silicate surfaces strongly influence the rates of silicate dissolution, hydration, and crystallization. Here, we determine the molecular-level structures, compositions, a ...

ALE/finite element modeling of an unconfined bubble plume in periodic domain: bubble shape and oscillation analysis

John Richard Thome, Gustavo Rabello Dos Anjos, Gustavo Charles Peixoto de Oliveira

This paper introduces a numerical model developed based upon the arbitrary Lagrangian-Eulerian/finite element scheme to analyze bubble plumes in a periodic domain. A spherical air bubble is immersed into a large pool of quiescent water to act as an unconfi ...

Incorporating an advanced aerosol activation parameterization into WRF-CAM5: Model evaluation and parameterization intercomparison

Yi Zhang, Athanasios Nenes, Xiuwei Zhang

Aerosol activation into cloud droplets is an important process that governs aerosol indirect effects. The advanced treatment of aerosol activation by Fountoukis and Nenes (2005) and its recent updates, collectively called the FN series, have been incorpora ...

Double-effect distillation and thermal integration applied to the ethanol production process

Adriano Viana Ensinas

A double-effect distillation system allows a significant reduction in energy consumption, since the condensers and reboilers of different columns can be integrated thermally. To achieve this goal, some columns operate under a vacuum, while others operate c ...

Activated carbon fibers for efficient VOC removal from diluted streams: the role of surface morphology

Albert Renken, Lioubov Kiwi, Guillaume Bastien Baur

The effect of the micropore structure of activated carbon fibers (ACFs) on the adsorption of toluene at low concentration (10-80 ppmv) was studied over two types of ACFs. Both adsorbents presented similar surface chemistry but different porous structure: o ...
