Thermal Characteristics of Spindle Supported with Water-Lubricated Hydrostatic Bearings

International Journal of Automation Technology, 2019
Characteristics of a spindle supported with water-lubricated hydrostatic bearings were experimentally investigated. In particular, this paper focuses on the thermal characteristics of the spindle. The flowrates of water as the lubricating fluid were measured separately for the radial and thrust bearings, in relation to the supply pressure.

In Situ Stress‐Dispersing Hydrogel Millispheres via Load Redistribution to Restore Nucleus Pulposus Metabolic Homeostasis

Advanced Science, EarlyView.
Local stress concentration disrupts metabolic homeostasis and induces inflammation in the nucleus pulposus (NP), thereby accelerating intervertebral disc degeneration (IDD). A biomimetic HA/ChS hydrogel millimeter sphere (ChS@HM) is developed to enable synergistic stress dispersion and sustained hydration lubrication.

Integrated Hydrophilic Interdigitated Network for Silicone Rubber via a Gradient Polarity Modification Strategy

Advanced Science, EarlyView.
This work overcomes the long‐standing challenge of hydrophilic modification of silicone rubber via a gradient polarity modification strategy. By constructing a hydrophilic interpenetrating network within cured SR, simultaneous surface‐to‐bulk modification is achieved while enabling monitoring through a Eu3+ complex fluorescent tracer.
