The motion, stability and breakup of a stretching liquid bridge with a receding contact line
, 2010 The complex behavior of drop deposition on a hydrophobic surface is considered by looking at a model problem in which the evolution of a constant-volume liquid bridge is studied as the bridge is stretched.

Contact angle hysteresis and static friction for two-dimensional droplets
Contact angle hysteresis of droplets will be examined in light of static friction between liquid drop and solid surface. Unlike frictions in solid-solid interfaces, pinning forces at contact points or contact lines would be the cause of friction. We will define coefficients of static friction and relate them with advancing and receding contact angles ...

Effects of Static Contact Angle and Roughness on Rolling Resistance of Droplet
Journal of the Microelectronics and Packaging Society, 2016 Carbon & Light Materials Application R&D Gropu, KITECH, Jeonju-city, Jellabuk-do 54853, Korea(Received March 14, 2016: Corrected March 21, 2016: Accepted March 25, 2016)초록: 본 연구에서는 소수성 구현을 위한 표면 거칠기가 접촉각과 접촉각 이력에 미치는 영향을 평가하였다. 초발수특성을 극대화하기 위해, 액적이 이동하기 위해 필요한 구름저항력을 제안하였으며, 이에 대한 평가를 통하여 표면에 형성한 패턴이 접촉각 이력 및 구름저항력에 큰 영향을 주는 것을 확인하였다.

Advanced Engineering Materials, EarlyView.Mg–Zn composites with a thickness of 0.21 mm were fabricated using roll bonding of a kirigami‐patterned Mg alloy inlay within a Zn matrix. Thermal activation following this process led to the formation of tailored intermetallic structures, which provided the composite with enhanced flexural strength.

Advanced Engineering Materials, EarlyView.Cermets (60 vol.% AISI 316L stainless steel, 40 vol.% recycled MgO), intended for use in aluminum electrolysis, were pre‐oxidized in three furnaces with different heating technologies and subjected to a cryolite corrosion test. The different atmospheres influenced the formation of oxide layers, which in turn affected corrosion resistance and ...

Sessile water droplets on insulating surfaces subject to high AC stress effect of contact angle [PDF]
, 2002 Surface pollution of outdoor high-voltage insulators is an important cause of flashover. We have undertaken an experimental study of electrical breakdown at the edges of a sessile water droplet on a planar, polymeric, insulating surface when subject to ...

Phase Field Failure Modeling: Brittle‐Ductile Dual‐Phase Microstructures under Compressive Loading
Advanced Engineering Materials, EarlyView.The approach by Amor and the approach by Miehe and Zhang for asymmetric damage behavior in the phase field method for fracture are compared regarding their fitness for microcrack‐based failure modeling. The comparison is performed for the case of a dual‐phase microstructure with a brittle and a ductile constituent.
