“…Therefore, the k of these steels could be approximated as that of zinc and phosphating coating. The k was proportional to the elastic modulus, and the elastic moduli of the zinc and phosphating coating were ∼97 GPa 45 and ∼140 GPa, 46 respectively. Therefore, the k of EGP and GIP steels was higher than EG and GI steels, while the N for the GI steel was a 4 times reduction in that for EG, EGP, and GIP steels.…”

Stick–slip behavior between friction pairs causes severe vibration problems such as abrasion and noise pollution, leading to material loss and deterioration in human health. This phenomenon is extremely complex because the surfaces of friction pairs have various asperities with different sizes. Therefore, it is of importance to understand the scale effect of asperities on the stick–slip behavior. Here, we selected four kinds of zinc-coated steels with multiscale surface asperities as a presentative example to reveal what types of asperities play the key role in affecting the stick–slip behavior. It is discovered that the stick–slip behavior is dominated by the density of small-scale asperities rather than large-scale asperities. High-density small-scale asperity increases the potential energy between asperities of the friction pairs, which leads to stick–slip behavior. It is suggested that decreasing the density of small-scale asperity on the surface significantly suppresses the stick–slip behavior. The present study reveals the scale effect of surface asperities on the stick–slip behavior and thus could offer a pathway to tailoring the surface topography of a wide range of materials for suppressing the stick–slip behavior.

“…The bare zinc phosphate coating showed a flat and elongated morphology of Zn 3 (PO 4 ) 2 crystals. 34 However, the BVZ composite coatings appeared as elongated plates or flower-like crystals. It could also be observed from the micrographs that the 0.2 wt% BVZ composite coating was denser than all the other coatings.…”

“…In the next few years, new material preparation technologies developed based on nanotechnology, such as wood modification technology, wood anti-degradative technology, wood composite preparation, etc., will greatly influence the development direction of the wood industry (Usmani et al 2018(Usmani et al , 2020. TiO2 is a type of inorganic antimicrobial agent with photo-catalytic activity with strong antimicrobial activity, high safety, good heat resistance, and weatherability (Kathavate and Deshpande 2020;). TiO2 will generate -OH, O 2-, H2O2, and other substances with strong oxidation property when TiO2 is exposed to light (Yang et al 2018).…”

“…These substances enter into the cell membrane and degrade the cell membrane after the metabolism is out of balance by changing the concentration of each component. The photo-catalytic and strong oxidation of TiO2 is used to act on substances in the cell and gradually promote cell death as TiO2 enters the cell (Kathavate and Deshpande 2020). Moreover, the strongly oxidizing -OH can rapidly and effectively decompose nutrients needed for the growth and survival of bacteria and play a bactericidal and bacteriostasis role (Gherardi et al 2018).…”

The sol-gel method was used to make nano-TiO2 and five Chinese herbal medicines of Sophora flavescens Alt., Hypericum perforatum L., Cnidium monnieri (L.) Cuss., Kochia scoparia (L.), and Zanthoxylum bungeanum Maxim. to prepare five kinds of nano-TiO2-Chinese herbal medicine composite anti-degradative wood. Populus tomentosa Carr was chosen as the wood sample. Indoor decay resistance test results showed that the resistance to weight gain and decay of nano-TiO2-Chinese herbal medicine composite anti-degradative wood noticeably increased compared with either Chinese herbal medicine modified wood or nano-TiO2 modified wood, reaching a strong decay resistance level. The results of the anti-loss test showed that the magnitude of loss of wood samples treated with nano-TiO2 and Chinese herbal medicine was noticeably reduced compared with that with just Chinese herbal medicine. It was found by scanning electron microscopy that the nano-TiO2 particles and the Chinese herbal medicine enter the wood cell cavity, and the wood vessels and pits were the main permeation channels. Fourier transform infrared analysis results showed that nano-TiO2 could not only enter the wood interior, and associate with wood components through physical adsorption to form hydrogen bonds, but also through the carboxyl groups in cellulose and hemicellulose, or the phenolic hydroxyl group in lignin, forming a coordinated chemical bond to fix it in the wood component.
