...applications. The mixture successfully and efficiently blocked the cement sample as the polymer-CO2 mixture flowed through the sample cracks. A posterior sample analysis did confirm the presence of polymer blocking the crack volume. Thus, a promising sealing agent for P&A and remediation has been identified...
...aluminium alloys for scanning and transmission electron microscopy, as it yields a good surface quality and large flat, electron-transparent areas. Like many chemical surface treatment procedures, the electropolishing process can create a Cu-rich layer between the aluminium matrix and the outermost aluminium...
The need to become more efficient in agriculture and the food industry exists parallel to the challenge of climate change. Meat and dairy production is the target of much scrutiny due to methane (CH4) emissions and global warming. On the other hand, it should be noted that two-thirds of the world’s...
In this chapter, we discuss how two-way coupled fluid flow and geomechanics can be modeled in the MATLAB Reservoir Simulation Toolbox (MRST) using the ad-mechanics module. A brief introduction to linear poroelasticity is provided, which is a common framework for studying geomechanics in the context of...
...oxides, Nd2O3, and Pr2O3 or their mixtures in different fluoride electrolytes composed of NdF3, PrF3, and LiF at ca. 1040 °C were monitored using a graphite probe inserted into the electrolyte during the dissolution process. Fast voltage sweeps of 100 V/s were applied to the graphite probe, and the current...
...present work quantifies the equilibrium defect and adsorbate chemistry on oxide surfaces in the presence of multiple gas components at elevated temperatures and sub-surface space charge. The concentrations of chemisorbed H2O and CO2 as well as surface protons and oxygen vacancies were calculated for Y-doped...
...objective of this research was to evaluate the potential of autonomous and connected sweepers for cleaning pavements and cycle ways. Supported by sustainable policies, the networks of cycle ways are growing considerably outside cities, and their maintenance is demanding in terms of economic resources. The...
...migration of bubbles in shear flow and observe that bubbles suspended in elastoviscoplastic emulsions organize into chains aligned in the flow direction, similarly to particles in viscoelastic fluids. To investigate the driving mechanism, we perform experiments and simulations on bubble pairs, using...
Background: Low and lower middle-income countries suffer lack of healthcare providers and proper workforce education programs, a greater spread of illnesses, poor surveillance, efficient management, etc., which are addressable by a central policy framework implementation. Accordingly, an eHealth policy...
