Advanced Functional Materials, EarlyView.A FeN4─O/Clu@NC‐0.1Ac catalyst containing atomically‐dispersed FeN4─O sites (medium‐spin Fe2+) and Fe clusters delivered a half‐wave potential of 0.89 V for ORR and an overpotential of 330 mV at 10 mA cm−2 for OER in 0.1 m KOH. When the catalyst was used in a rechargeable Zn–air battery, a power density of 284.5 mW cm−2 was achieved with excellent ...

Endolaryngeal contact pressures
Journal of Voice, 1998In this work, we present a new method for in vivo endolaryngeal contact pressure measurement with a miniature pressure transducer. Using this methodology, contact pressures can be measured during videoendoscopy at different locations between the artyenoids and also at various locations along the membranous vocal folds.

Steady State Contact Pressures in Electrical Contacts
IEEE Transactions on Components, Hybrids, and Manufacturing Technology, 1988The development of a numerical analysis is outlined for the thermoelastic effects in stationary electrical contacts. The steady-state pressure distribution at the contact, the change of contact area, and the separation of the contacting bodies are calculated. The temperature field obtained by Y.G. Yune and M.D.

Intraocular pressure with miniscleral contact lenses
Vestnik oftal'mologii, 2021According to literature data, some experts do not exclude the possibility that scleral lens wear could influence intraocular pressure.To evaluate the influence of rigid gas permeable miniscleral contact lenses on intraocular pressure (IOP), keratometry readings and corneal thickness, and to study the correlation between scleral (IOPs) and corneal (IOPc)

113 pages ; Supplemental file(s) description: None. ; Pressure field contact (PFC) generalizes the flat Winkler elastic foundation model to contact situations with arbitrary, non-convex, coarsely meshed solid geometries. PFC calculates the deformed contact surface, the traction distribution on that surface, and, consequently, the net wrench (the net ...

Superconductive Pressure Contacts
Journal of Applied Physics, 1968Superconductive contacts are nearly as old as superconductivity itself; in 1914, only three years after he had discovered superconductivity, Kamerlingh-Onnes1 found that a Pb–Pb contact carried supercurrents. Significantly, extreme cleaning of the contact surfaces was not necessary.

Contact pressure in indented elastohydrodynamic lubrication contacts
Proceedings of the Institution of Mechanical Engineers, Part J: Journal of Engineering Tribology, 2008Indents perturb the pressure and stress distribution and increase the failure risk. Existing theory for roughness deformation is extended to pure-rolling elastohydrodynamic lubrication indented contact pressure perturbations. First, a study of shallow indents is proposed, then it is modified to account for non-linear behavior of deeper indents.

Contact Force Decomposition Using Contact Pressure Distribution
IEEE Robotics and Automation Letters, 2017Many robotics applications involving contact with objects require the decomposition of an external force measured by a force sensor into its normal and shear components. In this paper, we present a general and effective contact force decomposition method based on the contact pressure distribution.

Contact in the honing of cylindrical holes is simulated. Nonlinear behavior of the mean contact pressure and the transfer coefficient is observed. These factors depend on the applied force and the surface relief, as well as the materials used in the tool and workpiece.
