...tungstate, La27(W,Mo)5O55.5−δ, and lanthanum chromite, La0.87Sr0.13CrO3−δ, have recently been shown to exhibit H₂ permeabilities among state-of-the-art. The present work deals with the long-term stability of these cercer membranes in line with concern of flux degradation and phase instability observed in...

...selected sulfides, oxysulfides, and oxysulfates. In this respect, dissolution of H₂S and H₂O into anion vacancies as SH– and OH–, respectively, was considered for La2O2S, La2O2SO4, and the perovskite sulfides SrZrS3 and BaZrS3. The structurally equivalent A-La2O3 and SrZrO3 were included for comparison...

...journey approach is increasingly being taken up by practitioners and researchers to support the design and management of services. As part of this approach, customers and internal resources are often involved as contributors of input in design and management processes. In the current literature on customer...

...flow during the onset period gives irregular saturation fronts and deviation from the square-root-of-time behavior. The deviation was caused by local variation in porosity and permeability or by a nonuniform wettability distribution, and was directly visualized or imaged by positron-emission tomography...

Laser beam welding (LBW) and laser-arc hybrid welding (LAHW) are attractive joining methods of medium thickness (10-20 mm) plates in a single pass welding technique. Both utilize high energy process in order to achieve high penetration depth and high welding speeds offering substantial increase in productivity...

...migration of bubbles in shear flow and observe that bubbles suspended in elastoviscoplastic emulsions organise 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...

Fluorinated polymers play a significant role in the Carbon Capture and Storage (CCS) value chain, which is considered as the most viable solution to limit the CO₂ emission in the atmosphere, with the potential to be applied at short-medium times. Indeed, among the various classes of polymers, fluorinated...

Security and scalability are core software qualities, which as non-functional aspects share certain characteristics and challenges in how they are approached during software development and operation. Based on expert interviews, this paper explores interactions and dependencies between security and scalability...

...production will depend on both the coke quality (impurities, structure) and the physical properties of the anode (density, permeability, electric resistivity). Here, a set of industrial anodes of different porosity and permeability, and a set of pilot-scale anodes of different calcined petrol cokes (CPC)...

...cell of this material causes the disks to overlap and introduces a series of challenges in the refinement procedure. These challenges and future work-arounds are discussed. The refined structure factors F200 and F600 are compared to X-ray diffraction and density functional calculated values, the latter...
