“…When the aerodynamic forcing is of concern, the axial gap plays a role as discussed in [47], since the forcing functions, as the wake velocity defect and the secondary flows, are stronger for low axial gaps.

The stator-rotor interaction is an important issue in turbomachinery design when the highest performances are targeted. Different characters mark the interaction process in high-pressure or low-pressure turbines depending both on the blade height and on the Reynolds number. For small blade heights, being the stator secondary flows more important, a more complex interaction is found with respect to the high blades, where the stator blade wake dominates. In low-pressure turbines, the stator wake promotes the transition to turbulent boundary layer, allowing for an efficient application of ultra-high lift blades. First, a detailed discussion of the flow physics is proposed for high-and low-pressure turbines. Some off-design conditions are also commented. Then, a design perspective is given by discussing the effect of the axial gap between the stator and the rotor and by commenting the effects of three-dimensional design on the interaction.

“…For instance, integration of microelectrodes (i.e., carbon, Pt, Au) with scanning electrochemical microscopy has enabled concurrent topography and electrochemical activity imaging in biological systems, albeit the detection range is still only limited to electroactive analytes. Inspired by nanopore platforms (i.e., biological nanopores or solid-state nanopores) that have been widely employed for various sensing applications, [14] Zhou et al described an alternative route, ion channel probes (ICPs), in which micropipettes modified with an artificial lipid bilayer that contained multiple ion channels (i.e., alpha hemolysin) have been integrated with scanning ion conductance microscopy (SICM), and preliminary results demonstrated the utilization of ICPs for topographical imaging. [15] In a following work, concurrent imaging and sensing of cyclodextrin with a similar micrometer-sized probe was reported.…”

Integration of dual-barrel membrane patch-ion channel probes (MP-ICPs) to scanning ion conductance microscopy (SICM) holds promise of providing a revolutionized approach of spatially resolved chemical sensing. A series of experiments are performed to further the understanding of the system and to answer some fundamental questions, in preparation for future developments of this approach. First, MP-ICPs are constructed that contain different types of ion channels including transient receptor potential vanilloid 1 and large conductance Ca2 -activated K channels to establish the generalizability of the methods. Next, the capability of the MP-ICP platforms in single ion channel activity measurements is proved. In addition, the interplay between the SICM barrel and the ICP barrel is studied. For ion channels gated by uncharged ligands, channel activity at the ICP barrel is unaffected by the SICM barrel potential; whereas for ion channels that are gated by charged ligands, enhanced channel activity can be obtained by biasing the SICM barrel at potentials with opposite polarity to the charge of the ligand molecules. Finally, a proof-of-principle experiment is performed and site-specific molecular/ionic flux sensing is demonstrated at single-ion-channel level, which show that the MP-ICP platform can be used to quantify local molecular/ionic concentrations.
