Ultraviolet antireflectance and high energy facets induced superhydrophilicity in SnO2 nano-arrayed thin films

Recent advances in prevailing antifogging surfaces: structures, materials, durability, and beyond

“…Specific structures and parameters are important elements affecting surface wetting behavior and optical properties. The bottomup method mainly includes sol-gel (solution) coating, 83,84 LBL assembly, [85][86][87] chemical vapor deposition, [88][89][90][91] physical vapor deposition, and redox reaction, 92 which can be used to prepare antifogging coatings with patterned structures or rough surfaces on different substrate materials. In addition, there are some unconventional methods, such as casting, 36,93 sparking, 94 hot pressing, 95,96 and blow molding, 97 used to directly fabricate the antifogging surface.…”

Fabrication of antireflective silver-capped tin oxide nano-obelisk arrays as high sensitive SERS substrate

“…Nano-arrayed SnO 2 thin films are required for this purpose which is achieved by spray pyrolytic deposition. SnO 2 nano-obelisk arrayed thin films are prepared on silicon substrates following the method adopted in our previous work for the deposition of SnO 2 nano-arrayed thin films [66]. The distribution of Ag nanocaps over SnO 2 nano-obelisk arrays determines the density of hot spots which is responsible for the EM enhancement contributing towards the SERS effect.…”

Major Obstacles and Optimization Strategies for the Electrode of Vanadium Redox Flow Battery

“…When this surface is exposed to water droplets, water molecules are readily attracted to these dangling bonds and form chemisorbed water layers. 46 Ahn et al proposed a study of N-doped TiO 2 laminates (NTO) deposited into heat-treated graphite felt (HGF) by ultrasonic spray pyrolysis. 47 The preparation process and contact angles are shown in Figure 4c.…”

“…The mechanism by which SnO 2 is hydrophilic may lie in having a high surface energy with a high density of dangling bonds on its high-energy crystalline surface. When this surface is exposed to water droplets, water molecules are readily attracted to these dangling bonds and form chemisorbed water layers . Ahn et al proposed a study of N-doped TiO 2 laminates (NTO) deposited into heat-treated graphite felt (HGF) by ultrasonic spray pyrolysis .…”
