Comparative Wear and Friction Analysis of Sliding Surface Materials for Hydrostatic Bearing under Oil Supply Failure Conditions

Advanced Engineering Materials, EarlyView.
Hydrostatic bearings excel in high‐precision applications, but their performance hinges on a continuous external supply. This study evaluates various material combinations for sliding surfaces to mitigate damage during supply failures or misalignment and to discover the most effective materials identified for enhancing the reliability and efficiency of

On the Soret effect in binary nonstoichiometric oxides—kinetic demixing of cuprite in a temperature gradient [PDF]

, 2005
The Soret effect in nonstoichiometric copper(I)-oxide (cuprite, Cu2-deltaO) has been studied experimentally by means of non-isothermal solid state galvanic cells (thermocells) under different boundary conditions.

Combining Metal Additive Manufacturing and Casting Technology: High Performance Cooling Channels for Electric Powertrain Components

Advanced Engineering Materials, EarlyView.
When realized as inserts in high‐pressure die casting, aluminum cooling channels for electric powertrain components and similar applications typically require a stabilizing filler to survive the process. The present study investigates relinquishing this filler using additively manufactured inserts promising performance improvements.

DMFC: Galvanic or electrolytic cell?

Electrochemistry Communications, 2006
We report measurements of local current distribution in a direct methanol fuel cell with single straight channels and segmented electrodes. The experiments directly confirm the existence of a bifunctional regime of DMFC operation: at low air flow rate the segments located close to the inlet of the oxygen channel generate current (galvanic domain ...

Electrical vestibular stimulation in humans. A narrative review [PDF]

, 2019
Background: In patients with bilateral vestibulopathy, the regular treatment options, such as medication, surgery, and/ or vestibular rehabilitation, do not always suffice. Therefore, the focus in this field of vestibular research shifted to electri-

Print‐and‐Plate Architected Electrodes for Electrochemical Transformations Under Flow

Advanced Functional Materials, EarlyView.
Typical flow cell electrodes are composed of stochastic porous carbon, limiting understanding of electrode structure‐performance relationships. This work describes an approach, termed “print‐and‐plate,” to prepare porous electrodes by direct ink writing followed by conformal metal coating.
