Konrad rykaczewski nist. edu - Homepage Articles 1–20 Jul 26, 2011 · In this work, we demonstrate that by transferring a small part of a macroscale sample to a novel thermally insulated sample platform we are able to mitigate flooding and electron heating problems typically associated with environmental scanning electron microscopy of water condensation. A vast array of low-surface tension fluids such as fluorocarbon refrigerants, carbon dioxide, and methane are used extensively in a number of industrial applications, and the In this work, we demonstrate that electron beam can a Electronic mail: konrad. Andrei Fedorov. Scott, Wanda Jones, Chonglei Hao, Shuhuai Yao, Zuankai Wang Mar 5, 2014 · Abstract Compared to the significant body of work devoted to surface engineering for promoting dropwise condensation heat transfer of steam, much less attention has been dedicated to fluids with lower interfacial tension. Hildreth, Ching P. Prior to his appointment at ASU, he was a research scientist at Massachusetts Institute of Technology working with Professor Kripa Vanarasi’s group and an NRC postdoctoral fellow at NIST. Mar 1, 2011 · Abstract Nanostructured superhydrophobic surfaces show promise as promoters of dropwise condensation and may lead to significant efficiency improvements in numerous industrial processes. Kripa Vanarasi’s group and NRC postdoctoral fellow at NIST. He received his BS (2005), MS (2007) and PhD (2009) in mechanical engineering from the Georgia Institute of Technology under supervision of Prof. Konrad Rykaczewski, Owen J. Aug 24, 2011 · We report formation of nano-to-microscale satellite droplets in the geometrical shadow of high contact angle primary drops during dropwise water condensation on a nanostructured superhydrophobic surface.

Oct 24, 2014 · We show that due to limits of vapor sorption within a liquid, nucleation is most favoured at the liquid–air interface and demonstrate that on spreading liquids, droplet submergence within the Prior to his appointment at ASU, he was a research scientist at MIT working with Prof. Oct 4, 2023 · We report formation of nano-to-microscale satellite droplets in the geometrical shadow of high contact angle primary drops during dropwise water condensation on a nanostructured superhydrophobic surface. Wong, Andrei G. 0003-6951/2011/98 9 /093106/3/$30. Scott. Fedorov, John H. The primary drops contribute to the heat transfer. 00 cause significant heating and fast evaporation of condensed drops during imaging at high magnification necessary for observation drop growth dynamics in the sub-10 m re-gime. In recent years Metal assisted Chemical Etching (MaCE) of silicon, in which etching is confined to a small region surrounding metal catalyst Mar 28, 2025 · Konrad Rykaczewski Associate Professor School for Engineering of Matter, Transport and Energy Ira A. Droplets with diameters below ~10 µm account for the majority of the heat transferred during dropwise condensation but their growth dynamics on superhydrophobic surfaces have not been systematically studied Jun 28, 2011 · Abstract In order to fabricate truly complex three-dimensional (3D) silicon nanostructures fabrication methods which expand beyond the concept of creation of straight 3D structures by direct extension of two dimensional (2D) patterns need to be developed. rykaczewski@nist.
