Influence of Platen Deformation Compensation on Motion Error of Hydrostatic Guideways
IEEE AccessThe deformation of a pressure plate induced by oil film pressure is unavoidable in hydrostatic guideways, and the fluid–structure interaction between the oil film and the supporting structure significantly affects motion accuracy.

Removing Oxide Layers and Retaining Oxide‐Free Steel Surfaces by Polishing in Oxygen‐Free Atmosphere
Advanced Engineering Materials, EarlyView.In this study, the efficacy of wet mechanical polishing under an oxygen‐free atmosphere for deoxidation and the retention of an oxide‐free steel surface are elucidated using X‐ray photoelectron spectroscopy. The methodology proved successful; however, the results were highly dependent on the preparation of the solvents used to clean the samples after ...

Oil Film and Pressure Characteristics of the Friction Pair
OALib, 2018 In order to improve the friction performance of the valve plate and improve the oil film bearing capacity of the valve plate, the influence of the fluid-solid coupling on the performance of the oil film of the valve plate was studied. The lubrication characteristics of the surface texture of the valve plate was studied systematically based on the ...

Advanced Functional Materials, EarlyView.This study presents a versatile approach to harnessing miscible aqueous domains, enabling liquid‐in‐liquid compartmentalization using a barrier formed in situ rather than bulk immiscibility. The barrier forms upon the complexation of multifunctional nanoparticles and ligands at the contact boundary of aqueous phases.

From Food to Power: Hydrogel Thermoelectrics for Ingestible Electronics
Advanced Functional Materials, EarlyView.We introduce a fully edible thermoelectric–electrochromic platform that harvests heat from food and converts it into a visible color change. N‐type and p‐type hydrogel thermoelectric generators connected in series power anthocyanin‐based electrochromic displays, demonstrating the feasibility of safe, biodegradable, ingestible systems for on‐food ...

Acoustic measurement of lubricant-film thickness distribution in ball bearings [PDF]
, 2006 An oil-film thickness monitoring system capable of providing an early warning of lubrication failure in rolling element bearings has been developed. The system is used to measure the lubricant-film thickness in a conventional deep groove ball bearing ...
