The Evolution of 21-cm Structure (EOS): public, large-scale simulations of Cosmic Dawn and Reionization

, 2016
We introduce the Evolution of 21-cm Structure (EOS) project: providing periodic, public releases of the latest cosmological 21-cm simulations. 21-cm interferometry is set to revolutionize studies of the Cosmic Dawn (CD) and epoch of reionization (EoR ...

Optimized Selenium‐Doped Nanocomposites for Enhanced Polymer Gel Performance in Permeability Reduction

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Excessive water production in mature oil fields necessitates robust shut‐off treatments, yet conventional polymer gels often fail under high‐temperature and high‐salinity conditions. This study aims to enhance gel thermal stability and mechanical strength by incorporating selenium‐doped Ag/AgO–ZnO nanocomposites synthesized via a novel green ...

The paper puzzle as an active learning tool in the teaching of anatomy: A qualitative study of perceptions in students and near‐peer teachers

Anatomical Sciences Education, EarlyView.
Abstract Active learning strategies enhance medical education by fostering self‐directed learning, communication, and problem‐solving skills. The paper puzzle, a game‐based learning approach, provides an engaging way to reinforce anatomical knowledge and promote collaboration.

The Fundamental Multi-Baseline Mode-Mixing Foreground in 21 cm EoR Observations

, 2013
The primary challenge for experiments measuring the neutral hydrogen power spectrum from the Epoch of Reionization (EoR) are mode-mixing effects where foregrounds from very bright astrophysical sources interact with the instrument to contaminate the EoR ...

Interfacial adsorption characteristics of surfactant‐modified nanoparticles: Equilibrium and dynamic effects of salinity at the oil–water interface

The Canadian Journal of Chemical Engineering, EarlyView.
Surfactant‐modified nanoparticles adsorb at the oil–water interface, enabling interfacial stabilization and microemulsion formation. Abstract This study systematically investigated the interfacial behaviour of silicon dioxide (SiO2) and aluminium oxide (Al2O3) nanoparticles (NPs) functionalized with cationic (CTAB), anionic (SDS), and nonionic (Triton ...

CO₂ dissolution-diffusion in clay inhibitor/oil systems and synergistic CCUS-EOR effects in strongly water-sensitive reservoirs

Scientific Reports
This study targeted a highly water-sensitive reservoir with high clay content (average 23.87%, mainly montmorillonite and illite), where waterflooding development induces hydration swelling of clay minerals, leading to pore-throat narrowing.

Using multiphase fluid flow modeling and time-lapse electromagnetics to improve 4D monitoring of CO 2 in an EOR reservoir [PDF]

, 2018
Understanding the changes in the saturation within a reservoir undergoing enhanced oil recovery (EOR) is crucial to optimizing production. We debut a novel, multiphase fluid flow modelling code, TOGA, to assist in modeling gas, oil, and water phases ...
