Dependence of boundary lubrication on the misfit angle between the sliding surfaces

, 2010
Using molecular dynamics based on Langevin equations with a coordinate- and velocity-dependent damping coefficient, we study the frictional properties of a thin layer of "soft" lubricant (where the interaction within the lubricant is weaker than the ...

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.

Modeling the elastic deformation of polymer crusts formed by sessile droplet evaporation

, 2006
Evaporating droplets of polymer or colloid solution may produce a glassy crust at the liquid-vapour interface, which subsequently deforms as an elastic shell.

Rational Fine‐Tuning of MOF Pore Metrics: Enhanced SO2 Capture and Sensing with Optimal Multi‐Site Interactions

Advanced Functional Materials, EarlyView.
A pore tuning strategy to amplify the multi‐site MOF‐SO2 interactions is proposed to achieve an enhanced trace SO2 capture and chemiresistive sensing in highly stable isostructural DMOFs by annelating benzene rings. This work provides a facile strategy to achieve tailor‐made stable MOF materials for specific multifunctional applications.

Modulating Two‐Photon Absorption in a Pyrene‐Based MOF Series: An In‐Depth Investigation of Structure–Property Relationships

Advanced Functional Materials, EarlyView.
This study investigates H4TBAPy‐based metal–organic frameworks (MOFs) ‐ NU‐1000, NU‐901, SrTBAPy, and BaTBAPy ‐ for multiphoton absorption (MPA) performance. It observes topology‐dependent variations in the 2PA cross‐section, with BaTBAPy exhibiting the highest activity.

Substrate Stress Relaxation Regulates Cell‐Mediated Assembly of Extracellular Matrix

Advanced Functional Materials, EarlyView.
Silicone‐based viscoelastic substrates with tunable stress relaxation reveal how matrix mechanics regulates cellular mechanosensing and cell‐mediated matrix remodelling in the stiff regime. High stress relaxation promotes assembly of fibronectin fibril‐like structures, increased nuclear localization of YAP and formation of β1 integrin‐enriched ...
