Barely porous organic cages for hydrogen isotope separation

Michele Ceriotti, Venkat Kapil, Sanggyu Chong, Ming Liu

The separation of hydrogen isotopes for applications such as nuclear fusion is a major challenge. Current technologies are energy intensive and inefficient. Nanoporous materials have the potential to separate hydrogen isotopes by kinetic quantum sieving, b ...

Modeling the Structural and Thermal Properties of Loaded Metal–Organic Frameworks. An Interplay of Quantum and Anharmonic Fluctuations

Michele Ceriotti, Venkat Kapil

Metal–organic frameworks show both fundamental interest and great promise for applications in adsorption-based technologies, such as the separation and storage of gases. The flexibility and complexity of the molecular scaffold pose a considerable challenge ...

Atomistic simulation of bio-relevant ionic and organic species interacting with rutile - Towards the understanding of apatite formation

Azade Yazdan Yar

Atomistic simulation methods, namely molecular dynamics and well-tempered metadynamics, are used in this thesis to investigate apatite formation from different aspects. First, ions which are more abundant in SBFs under physiological conditions were identif ...

Oxygen enriched network-type carbon spheres for multipurpose water purification applications

Sami Rtimi

Potassium hydroxide (KOH) modified network-type carbon spheres (CSs) with abundant oxygen-rich groups were synthesized using a simple hydrothermal carbonization (HTC) of glucose precursor and utilized for the adsorptive removal of cadmium(II) heavy metal a ...

Biporous Metal-Organic Framework with Tunable CO2/CH4 Separation Performance Facilitated by Intrinsic Flexibility

Seyedmohamad Moosavi, Berend Smit, Kyriakos Stylianou, Daniele Ongari, Peter George Boyd, Andrzej Gladysiak, Arunraj Chidambaram, Kathryn Suzanne Deeg, Kaili Yee Ordiz

In this work, we report the synthesis of SION-8, a novel metal-organic framework (MOF) based on Ca(II) and a tetracarboxylate ligand TBAPy(4-) endowed with two chemically distinct types of pores characterized by their hydrophobic and hydrophilic properties ...

In situ Control of the Adsorption Species in CO2 Hydrogenation: Determination of Intermediates and Byproducts

Andreas Züttel, Kun Zhao, Ligang Wang, Marco Calizzi, Emanuele Moioli

CO2 hydrogenation over catalysts is a potentially exciting method to produce fuels while closing the CO2 cycle and mitigating global warming. The mechanism of this process has been controversial due to the difficulty in clearly identifying the species pres ...

The underappreciated role of nonvolatile cations in aerosol ammonium-sulfate molar ratios

Hairun Guo, Athanasios Nenes

Overprediction of fine-particle ammonium-sulfate molar ratios (R) by thermodynamic models is suggested as evidence for interactions with organic constituents that inhibit the equilibration of gas-phase ammonia with aerosol sulfate and questions the equilib ...

Behavior of NDMA precursors at 21 full-scale water treatment facilities

Urs von Gunten

A source-to-tap evaluation of the origin and fate of chloramination N-nitrosodimethylamine (NDMA) precursors at 21 full-scale drinking water plants was conducted. Upstream wastewater discharges accounted for (on a median basis) similar to 16 ng L-1 NDMA fo ...
