Droplet evaporation on functional surfaces Günay, Ahmet Alperen; Gnadt, Marisa; Sett, Soumyadip; Oh, Junho; Miljkovic, Nenad (2018-01-01) © 2018 International Heat Transfer Conference. All rights reserved.Droplet evaporation is an important phenomenon governing many man-made and natural processes. Characterizing the rate of evaporation with high accuracy has attracted the attention of numerous scientists over the past century. Traditionally, researchers have studied evaporation by observing the change in the droplet size in a fixed time interval. However, the transient nature coupled with the significant mass-transfer governed gas-dynamics oc...
Droplet evaporation dynamics on microstructured biphilic, hydrophobic, and smooth surfaces Günay, Ahmet Alperen; Kim, Moon-Kyung; Yan, Xiao; Miljkovic, Nenad; Sett, Soumyadip (2021-07-01) Understanding liquid evaporation on surfaces is of utmost importance due to its impact on a plethora of industrial and natural processes. Over the past several decades, through chemical functionalization or surface structuring, wetting and non-wetting surfaces have been extensively developed and studied in an attempt to control liquid-surface interactions. More recently, surfaces with wettability patterns comprising of local wetting/non-wetting regions have received considerable attention. Although quantita...
Droplet Evaporation Dynamics of Low Surface Tension Fluids Using the Steady Method Günay, Ahmet Alperen; Gnadt, Marisa; Sett, Soumyadip; Vahabi, Hamed; Kota, Arun K.; Miljkovic, Nenad (2020-11-01) Droplet evaporation governs many heat- and mass-transfer processes germane in nature and industry. In the past 3 centuries, transient techniques have been developed to characterize the evaporation of sessile droplets. These methods have difficulty in reconciling transient effects induced by the droplet shape and size changes during evaporation. Furthermore, investigation of evaporation of microdroplets residing on wetting substrates, or fluids having low surface tensions (<30 mN/m), is difficult to perform ...
Evaporation-Induced Biomolecule Detection on Versatile Superhydrophilic Patterned Surfaces: Glucose and DNA Assay Beyazkılıç Ayas, Pınar; Saateh, Abtin; Bayindir, Mehmet; Elbuken, Caglar (2018-10-01) We introduce a droplet-based biomolecular detection platform using robust, versatile, and low-cost superhydrophilic patterned superhydrophobic surfaces. Benefitting from confinement and evaporation-induced shrinkage of droplets on wetted patterns, we show enrichment-based biomolecular detection using very low sample volumes. First, we developed a glucose assay using fluorescent polydopamine (PDA) based on enhancement of PDA emission by hydrogen peroxide (H2O2) produced in enzyme-mediated glucose oxidation r...
Polylactic acid recycling with environmentally benign fluids Bozcuoğlu, Çağla; Dilek Hacıhabiboğlu, Çerağ; Sezgi, Naime Aslı; Department of Chemical Engineering (2022-2) In the past few decades, petroleum-based polymers have been replaced by biodegradable polymers since they bring about environmental problems. Polylactic acid (PLA) is a good candidate for this replacement due to its biocompatible and biodegradable nature and favorable mechanical and thermal properties. Due to the increase in usage and demand, there will be a PLA waste problem in the near future. Although PLA is classified as a biodegradable polymer, only a few microorganisms, which are not present in all so...
