“…5 Different methods have been developed for the synthesis of ZnO nanorod arrays, such as thermal evaporation, 6 metal-organic chemical vapor deposition, 7 hydrothermal synthesis, 8 wet chemical route, 9 and electrochemical deposition. 10,11 However, the ZnO nanorod arrays reported usually show large differences in morphologies and intrinsic properties, even though synthesized by same method. Our previous study 12 found both diameter of the single nanorod and luminescence properties of the ZnO nanorod arrays vary obviously with growth temperature and solution concentration, respectively; Laurent et al 13 reported that ZnO nanorod arrays prepared on sputtered seed layer and spin-coated seed layer show very different hydrophobic properties.…”

A simple method for controllable growth of zinc oxide nanorod arrays by adjusting preparation conditions of their seed layers is studied. Mole ratio of zinc acetate to diethanol amine, concentration of the two chemicals in the solution, and addition of polyethylene glycol in the solution are identified as three key parameters that have a great influence on microstructure of the seed layers. Surface roughness and uniformity in thickness of the seed layer are found as main factors that determine the nanorod arrays' morphologies and alignments. Average diameter of the nanorods can be tuned from 106 to 336 nm; spacial distribution density of the nanorods is effectively controlled by adding polyethylene glycol. Advantage of this simple method lies in two aspects: First, it ensures that all the nanorod arrays have same chemical compositions as their morphologies change. Second, the controlled morphologies of zinc oxide nanorod arrays can significantly tune the hydrophobic properties. As demonstrated in their hydrophobic properties measurement, the static contact angle of water on their top surfaces can be finely tuned from 127 to 143 .

“…Subsequently, a significant amount of tiny Ni nuclei was rapidly produced on Cr/C film, and the localized metal ion concentrations close to the cathode surface were effectively refilled, which made great contributions to the crystal growth at same rate [28,36]. Furthermore, because of the increasing population of nucleation sites and mutual restriction of growing, the forming Ni grains ultimately had a more uniform shape, distribution, and smaller granular size, which thereby modified the deposit from 'rough' to relatively 'ordered' and 'flat' mode.…”

The Ni electrodeposition combined with multilayered structure film is a promising strategy in modern optical manufacturing, while less effort has been devoted to comprehending the electrochemical reaction process, which is essential for their practical applications. In view of this, the initial reduction dynamics and nucleation mechanisms of Ni electrodepositions on multilayer W/Si and Cr/C films were analyzed in this work, and the morphological, crystal, and mechanical characteristics of produced Ni electrodeposits were further determined and compared. The results show that the considerably irregular crystals accompanied by high tensile stress of 119.5 MPa were formed for the Ni electrodeposit on W/Si film, which were mainly attributed to the progressive nucleation process with more severe side reaction of hydrogen evolution. By contrast, the instantaneous nucleation mode with lower reduction resistance were revealed for the Ni electrodeposition on Cr/C film, which presented a comparatively fine–grained texture, less roughness, and smaller stress structure. To summarize, the more stable electrochemical reaction process and improved structure uniformity are obtained for the Ni electrodeposition on metal/C–based film, which offers a theoretical guidance for optimized fabrication of multilayer optical devices in extreme ultraviolet, X–ray, and neutron focusing fields.

A novel dopamine- and aluminum-doped zinc oxide (DAZO) sensing film was prepared by blending DAZO nanoparticles with silicone latex; this film has promising applications for the thermal runaway warning system of new energy batteries. The DAZO nanoparticles were generated by the coprecipitation–calcination method through the structure-orienting modification of eco-friendly polydopamine biomaterials, followed by the doping of aluminum and nitrogen into the zinc oxide lattice. Dopamine was used as a nitrogen source; it easily self-polymerizes to form polydopamine, which is then pyrolyzed and doped into the zinc oxide lattice. The negative temperature coefficient (NTC) effects of the DAZO film and the aluminum-doped zinc oxide (AZO) film below 150 °C were tested and compared. The results showed that the DAZO film had a more pronounced NTC effect than the AZO film because of the doped nitrogen element. DAZO films exhibited good recyclability and thermal stability during the high-low temperature NTC cycle test. X-ray diffraction, transmission electron microscopy, scanning electron microscopy, Fourier transform infrared spectroscopy, thermogravimetry/mass spectrometry (TG–MS), and energy dispersive X-ray spectroscopy were performed to characterize the fabrication of the synthesis mechanism of the DAZO nanoparticles. The NTC effects of DAZO films with varying aluminum doping amounts, varying dopamine doping amounts, and different pH values were investigated. Nitrogen doping in the conventional AZO nanoparticles enhanced the sensitivity and low-temperature NTC effect; this is because of the increase in the DAZO grain size due to doping and the structure–orientation of polydopamine, which further leads to the increase in the height of the grain boundary potential barrier. On the basis of the test results, an alarm response device at different temperatures was initially established, and its alarm response at different temperatures was simulated and tested, which showed the possibility of the application of the DAZO film to the runaway warning system for the new energy batteries.
