Low-Temperature Dynamics of Water Confined in Unidirectional Hydrophilic Zeolite Nanopores
Livia Eleonora Bove Kado, Umbertoluca Ranieri, Maria Rescigno
The dynamical properties of water molecules confinedin the unidirectionalhydrophilic nanopores of AlPO4-54 are investigated withquasi-elastic neutron scattering as a function of temperature downto 118 K. AlPO4-54 has among the largest pores known foralumin ...
AMER CHEMICAL SOC2023Shear strength and shear stiffness analysis of compacted Wyoming-type bentonite
Wyoming-type bentonite is one of the materials to be used as part of the Engineered Barrier System (EBS) in deep geological disposal facilities for the safe disposal of spent nuclear fuel.In the KBS-3 type repository, the canisters containing the spent fue ...
ELSEVIER2023Bragg edge tomography characterization of additively manufactured 316L steel
Roland Logé, Christian Leinenbach, Efthymios Polatidis, Markus Strobl, Nikola Kalentics
In this work we perform a neutron Bragg edge tomography of stainless steel 316L additive manufacturing samples, one as built via standard laser powder bed fusion, and one using the novel three-dimensional (3D) laser shock peening technique. First, we consi ...
AMER PHYSICAL SOC2022Systematic design of millisecond gasification reactor for the incorporation of gas-sieving nanopores in single-layer graphene
Kumar Varoon Agrawal, Kuang-Jung Hsu, Luis Francisco Villalobos Vazquez de la Parra, Shiqi Huang, Shaoxian Li
Etching an ensemble of vacancy defects (nanopores) in single-layer graphene (SLG) to obtain a high density of nanopores with an effective size that enables high-performance gas sieving is challenging. This is because nanopore nucleation and expansion are u ...
2021Multipulsed Millisecond Ozone Gasification for Predictable Tuning of Nucleation and Nucleation-Decoupled Nanopore Expansion in Graphene for Carbon Capture
Kumar Varoon Agrawal, Mounir Driss Mensi, Kuang-Jung Hsu, Luis Francisco Villalobos Vazquez de la Parra, Mostapha Dakhchoune, Shiqi Huang, Guangwei He, Heng-Yu Chi, Wan-Chi Lee
Predictable and tunable etching of angstrom-scale nanopores in single-layer graphene (SLG) can allow one to realize high-performance gas separation even from similar-sized molecules. We advance toward this goal by developing two etching regimes for SLG whe ...
2021Millisecond lattice gasification for high-density CO2- and O2-sieving nanopores in single-layer graphene
Emad Oveisi, Kumar Varoon Agrawal, Mounir Driss Mensi, Marina Micari, Luis Francisco Villalobos Vazquez de la Parra, Mostapha Dakhchoune, Shiqi Huang, Shaoxian Li, Deepu Joseph Babu
Etching single-layer graphene to incorporate a high pore density with sub-angstrom precision in molecular differentiation is critical to realize the promising high-flux separation of similar-sized gas molecules, e.g., CO2 from N2. However, rapid etching ki ...
2021Crystallization of gas-selective nanoporous graphene by competitive etching and growth: a modeling study
Kumar Varoon Agrawal, Soumajit Dutta
A robust synthesis methodology for crystallizing nanoporous single-layer graphene hosting a high density of size-selective nanopores is urgently needed to realize the true potential of two-dimensional membranes for gas separation. Currently, there are no c ...
2019Mass loss of density currents travelling over pourous bed
Anton Schleiss, Mário Jorge Rodrigues Pereira Da Franca, Sara Venuleo
Polluted liquids leaking from their storages over the surrounding gravel beds or oil spilling into aquifers, are examples of gravity currents moving over a porous terrain. Density-driven flows provoked by saline or temperature differences or turbidity curr ...
2019Hydro-chemo-mechanical behavior of a sand/bentonite mixture upon wetting paths
Lyesse Laloui, Alessio Ferrari, Donatella Manca
Sand/bentonite (S/B) mixtures are considered as backfilling materials for nuclear waste storage. The paper presents an experimental campaign that was carried out to investigate the swelling behavior of a S/B mixture, under different hydro-chemo-mechanical ...
HKGES2018Quantification of Viscous Creep Influence on Storage Capacity of Caprock
Lyesse Laloui, Roman Makhnenko, Ludovic Räss
In the light of growing concerns for the climate change, it is of particular interest for governments to encourage efficient capture and safe storage of large amounts of carbon dioxide in the subsurface. In this perspective and in order to accurately predi ...
