Gas Separation Membranes with Atom-Thick Nanopores: The Potential of Nanoporous Single-Layer Graphene

Kumar Varoon Agrawal, Kuang-Jung Hsu, Cédric Karel J Van Goethem, Luis Francisco Villalobos Vazquez de la Parra, Deepu Joseph Babu

Gas separation is one of the most important industrial processes and is poised to take a larger role in the transition to renewable energy, e.g., carbon capture and hydrogen purification. Conventional gas separation processes involving cryogenic distillati ...

Realistic Modelling of Dynamics at Nanostructured Interfaces Relevant to Heterogeneous Catalysis

Kevin Rossi

The focus of this short review is directed towards investigations of the dynamics of nanostructured metallic heterogeneous catalysts and the evolution of interfaces during reaction-namely, the metal-gas, metal-liquid, and metal-support interfaces. Indeed, ...

Interface Tracking Investigation of the Sliding Bubbles Effects on Heat Transfer in the Laminar Regime

Konstantin Mikityuk, Lubomír Bures

Helium gases are utilized to remove fission products from the molten salt fast reactor (MSFR) core during operation. Helium gases and other volatile fission products may be introduced into the intermediate heat exchanger channels. The effect of these gases ...

Centimeter-scale gas-sieving nanoporous single-layer graphene membrane

Kumar Varoon Agrawal, Mostapha Dakhchoune, Shiqi Huang, Guangwei He, Wan-Chi Lee

High-permeance, molecular-sieving, nanoporous single-layer graphene (NSLG) membranes are highly promising for gas separation. However, the formation of cracks during the transfer of NSLG to a low-cost porous support is difficult to avoid. These cracks are ...

Snapshots of mean ocean temperature over the last 700,000 yr using noble gases in the EPICA Dome C ice core

Adrien Michel

Together with the latent heat stored in glacial ice sheets the ocean heat uptake carries the lion’s share of glacial/interglacial changes in the planetary heat content but little direct information on the global mean ocean temperature (MOT) is available to ...

Basic creep of cement paste at early age - the role of cement hydration

Karen Scrivener, Pietro Lura

In this work, the uniaxial creep in compression during the first days of hydration is studied experimentally on cement pastes with w/c of 0.50. to order to assess the effect of the evolving microstructure on creep, the so-called equivalent systems are empl ...

Steam Gasification of Carbonaceous Feedstocks via a 1.5 kWth Hybrid Solar/Autothermal Reactor

Sophia Haussener, Iacopo Guscetti

A continuous method of steam gasification through hybridization of a solar reactor with an autothermal gasification process is proposed and tested. The ability to autothermally gasify a carbonaceous feedstock within a solar reactor enables round-the-clock ...

Disruption mitigation by injection of small quantities of noble gas in ASDEX Upgrade

Basil Duval, Emiliano Fable, Bernhard Sieglin, Gergely Papp

The most recent experiments of disruption mitigation by massive gas injection in ASDEX Upgrade have concentrated on small-relatively to the past-quantities of noble gas injected, and on the search for the minimum amount of gas necessary for the mitigation ...

Is ram-pressure stripping an efficient mechanism to remove gas in galaxies?

Elena Ricciardelli

We study how the gas in a sample of galaxies (M-* > 10(9) M-circle dot) in clusters, obtained in a cosmological simulation, is affected by the interaction with the intracluster medium (ICM). The dynamical state of each elemental parcel of gas is studied us ...
