Understanding water drop impact on meshes is valuable to design passive systems for atmospheric water collection. By investigating water drop impact on hydrophobic and superhydrophobic surfaces, here, we identify the different drop impact outcomes and build outcome maps within the pertinent parameter spaces, based on Weber number and contact angles...

Fog harvesting is a passive, low-cost and effective method to extract atmospheric water for domestic and agricultural use, particularly in humid and less-developed regions subject to drought. During years of research and construction of fog harvesters, it is found that the hydrophobic meshes are a good candidate due to their potential in efficient...

Additive manufacturing technologies are developed and utilized to manufacture complex, lightweight, functional, and non-functional components with optimized material consumption. Among them, vat polymerization-based digital light processing (DLP) exploits the polymerization of photocurable resins in the layer-by-layer production of three-dimensiona...

Electrodeposition is an effective and scalable method to impart desired structures to solid surfaces for superhydrophobicity, for example. Specifically, copper microcrystals can be grown using the electrodeposition by controlling the deposition parameters, such as the precursor composition, electrolyte acidity, bath temperature, and potential modul...

Additive manufacturing is a layer-by-layer strategy enabling the advanced design and fabrication of complex 3D objects and structures, overcoming geometry limitations and reducing waste production compared to conventional technologies. Among various additive manufacturing technologies, digital light processing (DLP), is an additive manufacturing te...

Evaluation of contact angles is a crucial and primary measurement in the wetting studies. Considering the high number of frames to be analyzed during quasi-static measurements, e.g. for advancing and receding contact angle measurements, manual analysis of hundreds of frames is unsustainable. Here we present DropenVideo, developed after Dropen [1],...

Contact angle measurement is an effective way to investigate solid surface properties. The introduction of low-cost digital cameras, as well as software and libraries for image analysis, has made contact angle measurement potentially accessible to every laboratory. In this review, we provide a comparison of the main methods developed to evaluate co...

Currently, the use of smart surfaces in the industries is well developed due to enhanced durability and qualification of fabricated layers as well as the increased values of products. Herein, the hydrophobic copper and cuprite surfaces were fabricated via the electrodeposition at various bath temperatures ranging from 15 to 90 °C by gal-vanostatic...

One of the relevant approaches to keep surfaces clean without a secondary process is to use the easy-to-clean and superhydrophobic surfaces technology. These surfaces have wide potential applications in the environment and industries. When the hydrophobicity is mixed with catalytic properties of copper oxide, a more useful surface for electrical an...

By developing the water purification technologies, the usage of superhydrophobic meshes are increased but the fabrication of durable and cost effective superhydrophobic meshes is still challenging. Here, the formation of hier-archical copper fractals on stainless steel meshes and their superhydrophobicity without any physical or chemical modificati...

Copper based layers were fabricated on gold/silicon (100) substrates by using square pulse electrodeposition at different deposition temperatures. The predominant crystalline plane on Cu2O samples at temperatures higher than 30 °C is (111), which is the most hydrophobic facet of Cu2O cubic structure. Different crystallite structures such as semiver...

Copper based microcrystals were fabricated on gold/Si(100) substrates using two- step electrodeposition method to examine wetting properties of copper surfaces. . It was observed that all samples were covered by copper based microcrystals and they showed tendency to hydrophobicity. It is expected that highly hydrophobic crystallite thin films can b...
