“…Superhydrophobic surfaces have a wide range of applications in many areas such as self-cleaning [65,66], oil-water separation [67][68][69], anti-icing [70,71], and drag reduction [72,73]. Because the superhydrophobic properties of a substance depend mainly on the surface topography and chemical composition of a material [74,75], femtosecond lasers offer two major advantages in this respect compared with conventional methods: (1) strong controllability, the method can be used to precisely control the microscopic topography of a material surface; (2) multi-material adaptability, the technique can be applied to almost any materials such as silicon, polydimethylsiloxane (PDMS), glass, grapheme, copper, titanium, and zinc.…”

Femtosecond laser fabrication has grown to be a major method of extreme manufacturing because of the extreme energy density and spatial and temporal scales of femtosecond lasers. The physical effects and the mechanism of interaction between femtosecond lasers and materials are distinct from those in traditional processes. The nonlinear and nonequilibrium effects of the interaction have given rise to new concepts, principles, and methods, such as femtosecond pulse durations are shorter than many physical/chemical characteristic times, which permits manipulating, adjusting, or interfering with electron dynamics. These new concepts and methods have broad application prospects in micro/nanofabrication, chemical synthesis, material processing, quantum control, and other related fields. This review discusses the cutting-edge theories, methods, measurements, and applications of femtosecond lasers to micro/nano-manufacturing. The key to future development of femtosecond laser manufacturing lies in revealing its fabrication mechanism from the electronic level and precisely regulating the electronic dynamics.

“…The lack of propensity in research activity to control the bubble adhesion arises from the fact that, due to interfacial energy balance, superhydrophilic surfaces are inherently superaerophobic . However, recent studies showed that even superhydrophobic surfaces could exhibit underwater superaerophobicity . This may lead to the development of novel substrates that can find potential applications at the interfaces where superhydrophobicity in air and underwater superaerophobicity are indispensable.…”

In spite of large amount of research in fabricating surfaces of varying wettability by biomimicking the naturally occurring surfaces, the work on fundamentally and industrially important air bubble adhesion on solid surfaces and its applications are still in the burgeoning stage. The present progress report provides a discussion and a critical evaluation of the recent literature available on the fabrication of superaerophilic/superaerophobic surfaces via synergic modification of surface topography and surface chemistry. An abridge on the physics behind bubble wetting on a solid in a liquid medium is deciphered here, considering the interfacial surface tension balance at the three‐phase contact line, Laplace pressure, hydrostatic pressure, and surface forces, respectively. Emphasis is made on the advancement in micro/nanofabrication technologies to fabricate surfaces that break the conventional wisdom of complementary behavior of water and air bubble contact angles. The progress report presented here also shines light on the mechanism of air bubble dynamics on solid surfaces and the latest developments in achieving surfaces of varied air bubble adhesion and its applications. Finally, the prospects of the superaerophobic and superaerophilic surfaces in the near future together with the challenges faced in accomplishing them are also insinuated.
