“…By shaking this tube, electrostatic interactions directed the self-assembly of these particles on the patterned surfaces. Conversely, Wang et al agitated millimeter-sized nylon beads in a container and subsequently deposited these particles on a separately charged electrification layer on which the particles assemble precisely on sequentially ordered sites. Collectively, these and other studies − highlight the ability of tribocharging to direct the self-assembly of particles.…”

Particle (monolayer) assembly is essential to various scientific and industrial applications, such as the fabrication of photonic crystals, optical sensors, and surface coatings. Several methods, including rubbing, have been developed for this purpose. Here, we report on the serendipitous observation that microparticles preferentially partition onto the fluorocarbon-coated parts of patterned silicon and borosilicate glass wafers when rubbed with polydimethylsiloxane slabs. To explore the extent of this effect, we varied the geometry of the pattern, the substrate material, the ambient humidity and the material and size of the particles. Partitioning coefficients amounted up to a factor 12 on silicon wafers, and even ran in the 100's on borosilicate glass wafers at zero humidity. Using Kelvin Probe Force Microscopy, the observations can be explained by tribo-electrification, inducing a strong electrostatic attraction between the 1 particles and the fluorocarbon zones, while the interaction with the non-coated zones is insignificant or even weakly repulsive.

Smart materials with electrically responsive characteristics and devices relying on different electrostatic effects can be directly driven by triboelectric nanogenerators (TENGs). The open circuit voltage from a TENG can easily reach thousands of volts with a separation distance of a few millimeters and this high output voltage can be used to effectively drive or control some devices with high internal resistance. This kind of combination is the most straightforward way for achieving a self-powered smart system. Hence, a detailed survey of electrically responsive materials and devices that can be successfully combined with TENG is summarized, including dielectric elastomers, piezoelectric materials, ferroelectric materials, electrostatic manipulators, electrostatic air cleaners, and field emission and mass spectrometers. Moreover, key factors in determining suitable materials or devices to work with TENG are clarified and an in-depth discussion of the current challenges related to these combined systems is provided. With the cost-effectiveness and simple manufacturing process, these TENG-based composite systems have great application prospects in the field of smart mechanics, human-machine interaction systems, intelligent storage systems, self-powered microfluidic chips, portable mass spectrometers, and so on.The ORCID identification number(s) for the author(s) of this article can be found under https://doi.org/10.1002/adfm.201806351. mainstream technique in the field of energy harvesting and self-powered systems. [1] Based on the coupling effect of triboelectrification and electrostatic induction, [2] TENG can convert almost all kinds of mechanical energies from vibrations, water waves, wind, raindrop, and human motions into electricity. [3] Comparing with other energy harvesting techniques, TENG is more attractive because of its advantages of simple fabrication, reliability, cost-effectiveness, and wide availability of low-frequency resources. [4] The TENG can serve as a sustainable power supply [5] by developing four different operation modes, [6] including vertical contactseparation mode, [7] lateral sliding mode, [8] single-electrode mode, [9] and freestanding triboelectric-layer mode. [10] Meanwhile, in order to improve the output performance of TENG, a great number of works have been done to optimize the materials and interfaces of the device. [11] Accordingly, the optimized TENG performance can achieve an area power density larger than 500 W m −2 , [12] a volume power density about 15 MW m −3 , [12] an instantaneous conversion efficiency larger than 70%, [13] and a total efficiency up to 85%. [14] As an advanced and durable energy source, the development of TENG has promoted and inspired many fields, such as wind [15] and ocean energy harvesting, [16] self-powered smart systems, [17] potable energy package, [18] highly sensitive tactile sensor, [19] and so on.Generally speaking, the output characteristic of TENG is a high open-circuit voltage (V OC ) reaching a few thousand volts and a low short-circuit...

“…Although the resulting patterns are highly controlled and arranged, the reproducibility of these devices seems highly sumptuous. Therefore, novel, cost-effective, and time-saving patterning methods have been investigated lately. ,− One of the proposed methods by Murillo et al focuses on the ZnO preference medium, where the nucleation and growth of the nanostructures take place on a certain seed layer comparatively faster than on the other thin-film layer . The study reports that the growth of patterned ZnO nanosheet arrays on the growth promoter aluminum nitride (AlN) seed layer is 4 times faster than that on neighboring gold (Au) thin film.…”

This work reports a one-pot chemical bath deposition (CBD) method for the preparation of selectively grown, morphology-tunable zinc oxide (ZnO) nanostructures provided via straightforward nanosecond fiber laser ablation. Nanosecond fiber laser ablation is different from lithographic methods due to its simple, time saving, and efficient film scribing abilities. Here, multiple morphologies of the ZnO nanostructures on the same substrate have been grown via laser ablation of the ZnO seeding layer. Selective and controlled ablation of the titanium layer, ZnO growth inhibitor, resulted in systematic growth of nanorod arrays, while the application of extensive fluence energies resulted in the penetration of the laser beam until the glass substrate induced the nanoflake growth within the same CBD environment. The laser penetration depth has been numerically investigated via COMSOL Multiphysics heat module simulations, and the optical variations between two nanostructures (nanorod and nanoflake) have been examined via Lumerical FDTD. The simultaneous growth of two morphologies served as an efficient tool for the enhancement of photoluminescence intensities. It increased the average charge carrier lifetimes of the thin films from approximately 2.01 to 9.07 ns under the same excitation wavelengths. The amplification in PL performances has been accomplished via the capstone of all-inorganic halide perovskite (IHP) deposition that brought a successful conclusion to lifetime responses, which have been increased by 1.4-fold. The development of IHP sensitized nanoscaled multimorphological ZnO thin films can, therefore, be used as potential nanomaterials for light-emitting-device applications.
