Liquid Adhesion to Curved Surface

Water Droplet on Solid

In our new report on adhesion of liquids to solids, entitled “Droplet Characteristics at the Maximum Adhesion on Curved Surfaces” and published in Langmuir, we analyze the effect of solid surface curvature on liquid droplet adhesion. The following is the abstract:
For applications involving droplet detachment from solid surfaces, it is vital to study the droplet characteristics (e.g., contact angle and base width) when the droplet is experiencing the maximum force that detaches the droplet (maximum adhesion state). Historically, such investigations were mainly conducted on flat 2-dimenional surfaces and the characteristics on curved surfaces with third dimension remain unknown. Thus, the generalized description of such characteristics has not been established yet. Here, by vertically pulling liquid droplets using a microbalance, we study the droplet characteristics at the maximum adhesion on curved homogeneous surfaces. Variables in this study include liquid surface tension, initial droplet base area, and the asymmetry in solid surface curvature. Results show that the contact angle is identical everywhere along the droplet perimeter on curved surfaces irrespective of the asymmetry in surface curvature because the surface curvature is a macroscopic parameter that cannot affect the contact angle, which is determined by surface microscopic properties. In addition, we found the droplet base is non-axisymmetric (not circular) at the maximum adhesion, opposing previous understanding that was formulated for flat surfaces. As a result, we propose a more generalized and quantitative description of the droplet characteristics at the maximum adhesion, derived from the component of the surface tension force acting along the droplet perimeter.

Top Scientist

Jarek Drelich

Jaroslaw Drelich

A new citation metrics was recently prepared by Mendeley; Mendeley is a free reference manager and an academic social network. They have created a publicly available database of 100,000 top-scientists (actual list is longer, ~160,000) that provides standardized information on citations, h-index, co-authorship adjusted hm-index, citations to papers in different authorship positions and a composite indicator. Separate data are shown for career-long and single year impact. Metrics with and without self-citations and ratio of citations to citing papers are given. Scientists are classified into 22 scientific fields and 176 sub-fields that include all disciplines of science, engineering and medicine. Field- and subfield-specific percentiles are also provided for all scientists who have published at least 5 papers. Mandeley ranks scientists in two categories: career-long and single-year citation. Career-long data are updated to end-of-2019.
Prof. Drelich is well recognized in both categories. He is ranked as number 7,818 (top ~0.1%) in the world, with only one other researcher/scientist from Michigan Tech that is listed ahead of Prof. Drelich. Regarding career-long category, he is already among the top 31,000 in the world (which makes him top 0.4-0.5%) due to his publications under the Science Metrix category of Physics & Astronomy, and two subfields of this category including Chemical Physics and Biomedical Engineering. There is only one active person from Michigan Tech, who is listed ahead of him.
This world-wide climbing of Prof. Drelich’s name reflects the quality of his team members and directions toward advanced materials and surfaces, biomedical engineering and his expertise in wetting phenomena. Many of his former and current students, postdoctoral fellows and collaborators contributed to this recognition.

Depinning Contact Line

Water Droplet on Solid

The mobility of a fakir state droplet on a structured surface is fundamentally determined by the effective length of a microscopic contact line. However, it is largely unknown how the surface topography determines the effective contact line length. Based on the direct measurement of droplet adhesion force and the visualization of contact line, our work, published in Physical Review Letters under the title “Topography-Dependent Effective Contact Line in Droplet Depinning“, shows that effective contact line length is topography-dependent as opposed to prior notion. On pored surfaces, contact line is not distorted, and the effective length approaches the droplet apparent perimeter regardless of pore dimensions. On pillared surfaces, the distortion of contact line is significantly dependent on the packing density of the pillar structures so that the effective length is as small as a pillar diameter on densely-packed pillars and as large as a pillar perimeter on sparsely-packed pillars, while changing linearly between the two extremes.
This paper is the result of our long-standing collaboration with Prof. Chang-Hwan Choi fromthe Stevens Institute of Technology.

Vascular Inflammation

H&E histology

Zinc (Zn) has emerged as a promising bioresorbable stent material due to its ideal corrosion behavior and excellent biocompatibility. However, for load bearing implant applications, alloying is required to boost its mechanical properties as pure Zn exhibits poor strength. Unfortunately, an increase in inflammation relative to pure Zn is a commonly observed side-effect of Zn alloys. Consequently, the development of a Zn-based alloy that can simultaneously feature improved mechanical properties and suppress inflammatory responses is a big challenge. In our new publication entitled “Analysis of vascular inflammation against bioresorbable Zn-Ag based alloys” and published in ACS Applied Bio Materials, a bioresorbable, biocompatible Zn-Ag-based quinary alloy was comprehensively evaluated in vivo, in comparison to reference materials. The inflammatory and smooth muscle cellular response was characterized and correlated to metrics of neointimal growth. We found that implantation of the quinary alloy was associated with significantly improved inflammatory activities relative to the reference materials. Additionally, we found that inflammation, but not smooth muscle cell hyperplasia, significantly correlates to neointimal growth for Zn alloys. The results suggest that inflammation is the main driver of neointimal growth for Zn-based alloys and that the quinary Zn-Ag-Mn-Zr-Cu alloy may impart inflammation-resistance properties to arterial implants.
