  • When two droplets on a superhydrophobic surface coalesce, the excess surface energy causes the merged droplet to jump away from the surface. Miljkovic et al.find that this process also causes the droplets to become charged, enabling them to be manipulated with an electric field.

  • Steam generation from solar energy is currently inefficient because of costly high optical concentration and large heat losses involved. Ghasemi et al. develop an efficient approach with internal efficiency up to 85% at low water temperature using a carbon-based material with a double-layer structure.

  • Achieving long-term sustainable dropwise condensation of low-surface-tension refrigerants has been a decades-long challenge. The authors introduce a coating that facilitates dropwise condensation of fluorinated refrigerants, significantly improving heat transfer and showcasing durability across various substrates.

  • Minimizing patient risk to thermal failure in wearable electronics typically requires complex circuit control, sensors, or passive materials. Here, Yoo et al. present an active materials system with a self-inflating bladder that delaminates upon excessive heat, mitigating the risk of thermal injury.

  • The understanding of salty water droplet freezing is limited. The authors examine the formation of brine film on top of frozen salty droplets and discover a new ice crystal growth pattern sprouting from the bottom of the brine film.

  • Hydrophobic condenser surfaces can improve power plant efficiency, but they suffer from poor durability. Here the authors developed a durable fluorinated diamond-like carbon coating that improved dropwise condensation and maintained hydrophobicity over three years of pure steam condensation on multiple metallic substrates.

  • By now a plethora of ultrathin hydrophobic coatings are available but their durability are not well developed. Here, the authors present a thin, durable and fluorine-free PDMS-based vitrimer coating that implements many desirable aspects like energy efficiency, durability and sustainability.

  • Thermal desalination processes such as air gap membrane distillation (AGMD) contribute to addressing water scarcity. Yashwant Yogi and colleagues test slippery liquid infused porous surfaces in the condensation plate of an AGMD apparatus. Models validated against experimental data suggest that AGMD energy efficiency could be boosted through the incorporation of such hydrophobic condensation surfaces, leading to improved droplet shedding.
