Influence of lubricant type on churning power loss of worm gear

Tribology and Materials
This paper presents the results of experimental tests of the churning power loss of a single-stage worm gear. The churning power loss is a load-independent loss that occurs when the gear churns through the lubricant. This study will solely look at how churning power losses are affected by mineral and synthetic oil on a test worm gear pair where the ...

Synchronizing the Osteochondral Regeneration Process through Spatial Patterning of Stable and Hypertrophic Cartilage Organoids

Advanced Materials, EarlyView.
Zonated osteochondral assembloid implants are engineered through scaffold‐free spatial assembly of induced pluripotent stem cell (iPSC)‐derived chondrocyte organoids and periosteum‐derived osteogenic organoids. Implanted into full‐thickness rat osteochondral defects, they promote hyaline‐like cartilage repair, support subchondral bone formation with ...

Metamaterial Antennas Enhance MRI of the Eye and Occipital Brain

Advanced Materials, EarlyView.
A radiofrequency antenna platform comprising planar and bend configurations is developed, incorporating structurally integrated epsilon‐negative metamaterial unit cells to enhance MRI. These antennas enable high‐resolution in vivo human MRI of the eye, orbit, and occipital brain. Comprehensive validation, including simulations, phantom experiments, SAR,

Elastomeric Micro‐Balloons for Remote Control of Cerebral Blood Flow and Real‐Time In vivo Imaging of Rodent Brain Response to Hypoperfusion

Advanced Materials, EarlyView.
This study reports the fabrication of MRI‐compatible elastomeric micro‐balloons via a multi‐step bubble casting process, where the monolithic elastomeric wall is selectively stiffened for reversible and controlled inflation and elasticity, depending on the target vessels for graded occlusion of cerebral arteries.

Oil Churning losses in Automatic Transmission

, 2013
På senare år har diskussionen om fordonens miljöpåverkan blivit allt mer intensiv. Fordonstillverkarna bygger bilar, lastbilar, hjullastare, etc., vars bränsleeffektivitet årligen når nya höjder. Var finns utrymme för förbättringar? Drivlinan är en del av fordonet där många olika förlustkällor påträffas; t.ex.
