High-Throughput Nanopore Fabrication and Classification Using Xe-Ion Irradiation and Automated Pore-Edge Analysis

Aleksandra Radenovic, Andras Kis, Martina Lihter, Mukesh Kumar Tripathi, Mukeshchand Thakur, Sanjin Marion, Michal Daniel Macha

Large-area nanopore drilling is a major bottleneck in state-of-the-art nanoporous 2D membrane fabrication protocols. In addition, high-quality structural and statistical descriptions of as-fabricated porous membranes are key to predicting the corresponding ...

Factors affecting the reactivity of slag at early and late ages

Karen Scrivener, Yosra Briki, Mohsen Ben Haha

This study investigates the difference between the reactivity of slag in NaOH solution (w/s = 100) and in cement paste (w/b = 0.4). The reactivity of slag is much higher in NaOH solution than in cement paste. When the NaOH solution is saturated with portla ...

Maximizing the use of supplementary cementitious materials (SCMs) in blended cements

Yosra Briki

Partial replacement of clinker with supplementary cementitious materials (SCMs) is an effective approach to reduce CO2 emissions related to cement production. However, there is a maximum substitution level with SCMs beyond which strength decreases. The und ...

Supercritical CO2 injection and residence time in fluid-saturated rocks: Evidence for CO2 and mineral dissolution and effects on rock integrity

Lucas Xan Pimienta, Ke Liu

CO2 injection and storage in geological reservoirs is an attractive prospect for mitigating the anthropogenic production of greenhouse gases and global warming. The technology could lead to mineral precipitation and therefore stable storage over geological ...

Chemical Influence of Pore Pressure on Brine Flow in Clay-Rich Material

Roman Makhnenko, Etienne André Cassini, Danila Mylnikov

Hydromechanical properties of shales are complex due to the involved ma-terial structure, with the solid matrix being mainly formed by swelling clays and porosity dominated by nanometer scale tortuous voids with large aspect ratios. Intrinsic permeability ...

Utilisation of alkali activated glass powder in binary mixtures with Portland cement, slag, fly ash and hydrated lime

Hamed Maraghechi

This paper evaluates feasibility of alkali activation to boost the reactivity and cementitious properties of recycled glass powder ( GP), when it is used in four different binary mixtures with ordinary Portland cement ( OPC), alkali activated slag or fly a ...

When neighbours become competitors - Autotrophic assimilation rates of individual symbionts depend on local density when Stylophora pistillata is regularly fed

Anders Meibom, Thomas Krüger, Maoz Fine

The symbiosis between dinoflagellate microalgae and their cnidarian host represents the fundamental mechanism that allows zooxanthellate corals to access the inorganic nutrient pool of the surrounding seawater and conserve and recycle nutrients within thei ...

MUNICIPAL WATER/WASTEWATER AGENCY SERVICES: SHIFTING FROM LINEAR TO CIRCULAR

Municipal water/wastewater agencies play an essential role in community well-being. Traditionally, municipal water/wastewater agencies have followed a linear (“take, make, dispose“) mode of thinking based on resource extraction. Often, the model follows th ...

Determining The Potential Of Salinity Gradient Energy Source Using An Exergy Analysis

Arash Emdadi

Mixing of fresh (river) water and salty water (seawater or saline brine) in a control fashion would produces an electrical energy known as salinity gradient energy (SGE). Two main conversion technologies of SGE are membrane-based processes; pressure retard ...
