“…111,113 To further upgrade the electrochemical oxidation performance of the planar/bare BDD anodes, the surface modification is highly recommended. 116,117 Nanocrystallizing, 118 chemical etching, 119 electrochemical anodizing, 120,121 porous structuring, 122,123 and hybridizing 116,123 are proved as the efficient strategies to achieve better electrochemical performance of BDD electrodes. The general idea of these methods is to improve the active surface area, enhance the intrinsic electrochemical activity and boost the durability of electrodes.…”

“…The inuence of surface termination of BDD electrodes on organic oxidation has been investigated in several studies. 25,26 The O-terminated BDD surface obtained via anodic polarization exhibits increased hydrophilicity, resulting in enhanced oxidation power of the anode. Souza et al investigated the mineralization efficiency of 2,4-dichlorophenoxyacetic acid with respect to the sp 3 /sp 2 ratio in BDD electrodes.…”

“…Nanomaterial products from industrialization and the increased popularity of these nanomaterial products also emit a significant amount of ultrafine particles. The incomplete combustion process is used to form polycyclic aromatic hydrocarbons (PAH), which are a compound of more than 100 different chemicals [1,163]. The pollutant PAH can exist in different forms (volatile, semi-volatile) and they may combine with another pollutant particle in the atmosphere.…”

“…Understanding particulate matter transport, movement, and deposition in the terminal airways is the primary step to predicting and helps preventing respiratory diseases. Various human activities like combustion of fossil fuels in vehicles, industrial processes, thermal coal combustion, biomass burning, and many other sources produce a significant amount of particulate matter (PM) [1]. The uptake of PM through nasal or oral inhalation follows a complicated transport through the irregular dichotomous branching airways.…”

The understanding of complex inhalation and transport processes of pollutant particles through the human respiratory system is important for investigations into dosimetry and respiratory health effects in various settings, such as environmental or occupational health. The studies over the last few decades for micro- and nanoparticle transport and deposition have advanced the understanding of drug-aerosol impacts in the mouth-throat and the upper airways. However, most of the Lagrangian and Eulerian studies have utilized the non-realistic symmetric anatomical model for airflow and particle deposition predictions. Recent improvements to visualization techniques using high-resolution computed tomography (CT) data and the resultant development of three dimensional (3-D) anatomical models support the realistic representation of lung geometry. Yet, the selection of different modelling approaches to analyze the transitional flow behavior and the use of different inlet and outlet conditions provide a dissimilar prediction of particle deposition in the human lung. Moreover, incorporation of relevant physical and appropriate boundary conditions are important factors to consider for the more accurate prediction of transitional flow and particle transport in human lung. This review critically appraises currently available literature on airflow and particle transport mechanism in the lungs, as well as numerical simulations with the aim to explore processes involved. Numerical studies found that both the Euler–Lagrange (E-L) and Euler–Euler methods do not influence nanoparticle (particle diameter ≤50 nm) deposition patterns at a flow rate ≤25 L/min. Furthermore, numerical studies demonstrated that turbulence dispersion does not significantly affect nanoparticle deposition patterns. This critical review aims to develop the field and increase the state-of-the-art in human lung modelling.
