AbstractSeventy percent of global electricity is generated by steam-cycle power plants. A hydrophobic condenser surface within these plants could boost overall cycle efficiency by 2%. In 2022, this enhancement equates to an additional electrical power generation of 1000 TWh annually, or 83% of the global solar electricity production. Furthermore, this efficiency increase reduces CO2 emissions by 460 million tons /year with a decreased use of 2 trillion gallons of cooling water per year. However, the main challenge with hydrophobic surfaces is their poor durability. Here, we show that solid microscale-thick fluorinated diamond-like carbon (F-DLC) possesses mechanical and thermal properties that ensure durability in moist, abrasive, and thermally harsh conditions. The F-DLC coating achieves this without relying on atmospheric interactions, infused lubricants, self-healing strategies, or sacrificial surface designs. Through tailored substrate adhesion and multilayer deposition, we develop a pinhole-free F-DLC coating with low surface energy and comparable Young’s modulus to metals. In a three-year steam condensation experiment, the F-DLC coating maintains hydrophobicity, resulting in sustained and improved dropwise condensation on multiple metallic substrates. Our findings provide a promising solution to hydrophobic material fragility and can enhance the sustainability of renewable and non-renewable energy sources.

Surface patterning of inorganic nanoparticles through site-selective functionalization with mixed ligand shells or additional inorganic material leads to tailored nanomaterials with potentially novel and/or multifunctional properties.

Sometimes, the most interesting discussions occur over a beer or a glass of your favorite vino. (Bonus points if you can remember what was said the next morning!) That’s the concept behind Suds & Science, a monthly event that brings scientists face-to-face with the general public in a neighborhood bar. Each session kicks off with a short and enlightening presentation, after which the floor is open for discussion between the audience and the speaker. We cover a wide variety of topics that can range from the science of beer to superhero physics to the genius of genomes.
