Phase velocity and attenuation of compressional and shear waves in the two materials PMMA and Eccosorb MF-117 were measured as function of frequency and temperature, using a broadband through-transmission technique. Two pairs of transducers were used for the measurements, one pair with center frequency...
The presentation explores the evolution and future trends of edge processing from localised micro-edge devices to an interconnected “meta-edge” fabric, forming the foundation for next-generation generative and agentic AI systems. ...
...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...
