Colloids and InterfacesBy using clear vapor–liquid interface line images of the liquid inside the capillary, the measurement coordinate points of the vapor–liquid interface line were measured. A new method for measuring liquid contact angle has been proposed, which was used to

Arthritis Care &Research, Accepted Article.Objective Foot orthoses are thought to improve pain by potentially modifying internal mechanical forces. To test this, we explored whether foot orthoses can modify patterns of bone marrow lesions (BMLs) in people with midfoot pain. Methods Forty‐two people were recruited with midfoot pain and MRI‐confirmed midfoot BMLs.

Advanced Biology, EarlyView.In this study, Seaman et al. develop a co‐culture assay to examine interactions between prostate cancer cells and mineralized osteoblasts in a microfluidic platform. The authors collect conditioned media from static or flow‐stimulated osteocytes and demonstrate that mechanical loading of osteocytes regulates the growth of prostate cancer cells and ...

Bubble dynamics atop an oscillating substrate: Interplay of compressibility and contact angle hysteresis [PDF]
, 2011 We consider a sessile hemispherical bubble sitting on the transversally oscillating bottom of a deep liquid layer and focus on the interplay of the compressibility of the bubble and the contact angle hysteresis.

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

Estimation of bearing contact angle in-situ by X-ray kinematography [PDF]
, 1982 The mounted, preloaded contact angle of the structural bearings in the assembled design mechanical assembly was measured. A modification of the Turns method is presented, based upon the clarity and definition of moving parts achieved with X-ray technique

Liquid droplets on a free-standing glassy membrane: deformation through the glass transition
, 2017 In this study, micro-droplets are placed on thin, glassy, free-standing films where the Laplace pressure of the droplet deforms the free-standing film, creating a bulge. The film's tension is modulated by changing temperature continuously from well below

A Different Perspective on the Solid Lubrication Performance of Black Phosphorus: Friend or Foe?
Advanced Engineering Materials, EarlyView.Researchers investigate black phosphorus (BP) as a standalone solid lubricant coating through ball‐on‐disc linear‐reciprocating sliding experiments in dry conditions. Testing on different metals shows BP doesn't universally reduce friction and wear. However, it achieves 33% friction reduction on rougher iron surfaces and 23% wear reduction on aluminum.

Advanced Engineering Materials, EarlyView.Laser surface texturing significantly improves the corrosion resistance and mechanical strength of 3D‐printed iron polylactic acid (Ir‐PLA) for marine applications. Optimal laser parameters reduce corrosion by 80% and enhance tensile strength by 25% and ductility by 15%.
