A super liquid-repellent hierarchical porous membrane for enhanced membrane distillation

Autor: Youmin Hou, Prexa Shah, Vassilios Constantoudis, Evangelos Gogolides, Michael Kappl, Hans-Jürgen Butt

Publikováno v: Nature Communications, Vol 14, Iss 1, Pp 1-11 (2023)

Abstract Membrane distillation (MD) is an emerging desalination technology that exploits phase change to separate water vapor from saline based on low-grade energy. As MD membranes come into contact with saline for days or weeks during desalination,

Chemically robust superhydrophobic surfaces with a self‐replenishing nanoscale liquid coating

Autor: Xiaoteng Zhou, Pranav Sudersan, Diego Diaz, Benjamin Leibauer, Chirag Hinduja, Fahimeh Darvish, Pravash Bista, Lukas Hauer, Manfred Wagner, Werner Steffen, Jie Liu, Michael Kappl, Hans‐Jürgen Butt

Publikováno v: Droplet, Vol 3, Iss 1, Pp n/a-n/a (2024)

Abstract Due to poor chemical robustness, superhydrophobic surfaces become susceptible to failure, especially in a highly oxidative environment. To ensure the long‐term efficacy of these surfaces, a more stable and environmentally friendly coating

Effects of liquid surface tension on gas capillaries and capillary forces at superamphiphobic surfaces

Autor: Mimmi Eriksson, Per M. Claesson, Mikael Järn, Viveca Wallqvist, Mikko Tuominen, Michael Kappl, Hannu Teisala, Doris Vollmer, Joachim Schoelkopf, Patrick A. C. Gane, Jyrki M. Mäkelä, Agne Swerin

Publikováno v: Scientific Reports, Vol 13, Iss 1, Pp 1-13 (2023)

Abstract The formation of a bridging gas capillary between superhydrophobic surfaces in water gives rise to strongly attractive interactions ranging up to several micrometers on separation. However, most liquids used in materials research are oil-bas

Enhanced condensation heat transfer by water/ethanol binary liquids on polydimethylsiloxane brushes

Autor: Shuai Li, Diego Diaz, Michael Kappl, Hans‐Jürgen Butt, Jie Liu, Youmin Hou

Publikováno v: Droplet, Vol 1, Iss 2, Pp 214-222 (2022)

Abstract Enhancing heat transfer efficiency by liquid condensation plays a critical role in recovering and utilizing low‐grade heat. However, overall heat transfer efficiency is commonly limited by the inefficient vapor–liquid phase transition fl

High-throughput synthesis of CeO2 nanoparticles for transparent nanocomposites repelling Pseudomonas aeruginosa biofilms

Autor: Massih Sarif, Olga Jegel, Athanasios Gazanis, Jens Hartmann, Sergi Plana-Ruiz, Jan Hilgert, Hajo Frerichs, Melanie Viel, Martin Panthöfer, Ute Kolb, Muhammad Nawaz Tahir, Jörg Schemberg, Michael Kappl, Ralf Heermann, Wolfgang Tremel

Publikováno v: Scientific Reports, Vol 12, Iss 1, Pp 1-16 (2022)

Abstract Preventing bacteria from adhering to material surfaces is an important technical problem and a major cause of infection. One of nature’s defense strategies against bacterial colonization is based on the biohalogenation of signal substances
