The super-hydrophobic copper surface was obtained by using a nanosecond pulsed laser. Different micro-and nano-structures were fabricated by changing the laser scanning interval and scanning speed, before heating in an electric heater at 150 • C for two hours to explore the effect of laser parameters and heat treatment on the wettability of the copper surface. It was found that the laser-treated copper surface is super-hydrophilic, and then, after the heat treatment, the surface switches to hydrophobic or even super-hydrophobic. The best super-hydrophobic surface's apparent contact angle (APCA) was 155.6 • , and the water sliding angle (WSA) was 4 • . Super-hydrophobic copper is corrosion-resistant, self-cleaning, and dust-proof, and can be widely used in various mechanical devices.In order to find the best super-hydrophobic metal surface, we should know the reasons behind certain materials being super-hydrophobic.A dense column micro-or nano-structure is the key factor causing a super-hydrophobic surface. Thus, when we look for a super-hydrophobic surface, micro-and nano-scale dense column structures, such as the microstructures of lotus leaves, bird feathers, and butterfly wings, are considered. Although there are many ways to fabricate the hybrid micro/nano-structure on the material surface, such as chemical vapor deposition, chemical etching, nano-imprint lithography, electrode position, etc., there are various problems in their application [8][9][10][11][12][13][14][15][16][17]. For example, the size of the micro/nano-structure formed by the chemical etching method is very sensitive to external conditions such as temperature and concentration of chemical solution. In addition, etching reagents are mostly corrosive reagents with safety and environmental issues. Unlike the above methods, lasers can fabricate and precisely control the size of micro/nano-structures [18][19][20][21][22][23]. Therefore, laser processing can be used to quickly obtain micro/nano-structures. Recent studies found that the surfaces of metal oxides and nanostructures formed by laser ablation are initially hydrophilic or even super-hydrophilic; however, over time, they become hydrophobic, and sometimes even super-hydrophobic in air after two weeks to two months [24]. Several mechanisms were proposed to explain this phenomenon. Chang et al. proposed that the deoxidation of copper oxide could effectively promote the development from a hydrophilic to a super-hydrophobic surface [25,26]. Boinovich et al. believed that metal oxides adsorbed organics in the air, resulting in the transition from a super-hydrophilic to super-hydrophobic surface [27,28]. It can be seen that, although most researchers extensively studied this topic, there is obvious controversy regarding the mechanism of the wettability transition behavior.In this paper, a rapid method of fabricating a super-hydrophobic surface on a copper plate was studied. Micro/nano-structures were fabricated on copper surfaces by laser ablation, which then became super-hydrophobic after heat t...

“…In addition to the above-mentioned common methods for preparing BN, other methods can also be realized, such as wet chemical method (also called chemical liquid deposition (CLD)) [145] and solid state synthesis method, [146] which are extended by CVD method.

Due to special non-metallic polar bond between the III group (with certain metallic properties) element boron (B) and the V group element nitrogen (N), boron nitride (BN) has unique physical and chemical properties such as strong high-temperature resistance, oxidation resistance, heat conduction, electrical insulation and neutron absorption. Its unique lamellar, reticular and tubular morphologies and physicochemical properties make it attractive in the fields of adsorption, catalysis, hydrogen storage, thermal conduction, insulation, dielectric substrate of electronic devices, radiation protection, polymer composites, medicine, etc. Therefore, the synthesis and properties of BN derived materials become the main research hotspots of lowdimensional nanomaterials. This paper reviews the synthetic methods, overall properties, and applications of BN nanostructures and nanocomposites. In addition, challenges and prospect of this kind of materials are discussed.

“…However, the long-term jet impact will cause erosion damage to the surface of the ship plate substrate, which results in the deterioration of the mechanical properties of the steel plate surface and thus severely affects the service life of the ship. Presently, water jet studies mostly focus on the influence of jet-related parameters on material processing technology [21][22][23][24][25][26][27] and also on highly brittle materials such as rocks and minerals [28][29][30]. However, few studies have investigated the interaction and erosion mechanism between a water jet and Grade A marine steel.…”

To investigate the interaction and erosion mechanisms between an ultrahigh-pressure water jet and the surface of Grade A marine steel, this study used the ANSYS FLUENT software to simulate the hydrodynamic characteristics of an ultrahigh-pressure water jet. To erode the Grade A marine steel, a water jet with ultrahigh-pressure (200 MPa, 40 L/min) was used. An ASMC2-4 resistance strain gauge collected the dynamic strain signal at the back of the sample during jet impingement, and the simulation results were compared to experimental results. A scanning electron microscope (SEM), X-ray diffractometer (XRD), energy dispersive spectrometer (EDS), and other equipment were used to observe and analyze the phase before impact and the material surface morphology and element distribution after impact. The results reveal that as the wall shear stress increased with the target distance, the energy loss of the jet could be reduced by changing the jet incidence angle, and the peak value of the wall shear stress increased. Under the pressure of 200 MPa, the average microstrain at the back side of the impact center area of the Grade A marine steel was 180 × 10−6, and the microstrain amplitude was 35 × 10−6–50 × 10−6. The impact force of the water jet on the Grade A marine steel produced alternating stress with cyclic fluctuation. The experimental results are consistent with the simulation results. Under the alternating jet stress action, fatigue failure and cavitation failure occurred on the sample surface, which was characterized by a spalling pit, layer erosion, and cavitation hole morphology. The surface stripping model of the Grade A marine steel under an ultrahigh-pressure water jet was established, and the interaction mechanism and erosion mechanism between the ultrahigh-pressure water jet and the surface of the Grade A marine steel were elucidated.
