“…The main factors affecting the membrane separation efficiency include membrane characteristics (i.e., membrane flux, membrane pore size, hydrophobicity) and pollutant characteristics (i.e., molecular weight, solubility, charge). At present, the research of membrane treatment is mainly focused on optimizing the process and developing the combined process of membrane treatment and other processes (Fan, Luo, et al, 2019;Li, Zhang, Zeng, et al, 2019;Li, Zhang, Xia, Wang, et al, 2019;Li, Zhang, Hu, et al, 2019;Li, Sun, Zhang, Feng, et al, 2019;Li, Yuan, Gao, et al, 2019).

“…With the development of society and the improvement of living standard, the production and consumption of PPCPs are increasing (Papageorgiou, Zioris, Danis, Bikiaris, & Lambropoulou, 2019). PPCPs can enter the environment with domestic wastewater, hospital wastewater, pharmaceutical wastewater, landfill leachate, and animal manure (Li, Gao, et al, 2019; Li, Li, et al, 2019; Li, Zhang, Zeng, et al, 2019; Li, Liu, Zhang, Li, et al, 2019; Li, Zhang, Xia, Wang, et al, 2019; Li, Zhang, Hu, et al, 2019; Li, Sun, Zhang, Feng, et al, 2019; Li, Wang, et al, 2019; Li, Yuan, Gao, Wang, & Sheng, 2019). At present, PPCPs of ng/L–μg/L level have been detected in water, soil, wastewater, and sludge of many countries and regions (Alonso, Demetrio, Capparelli, & Marino, 2019; Pérez‐Lemus, López‐Serna, Pérez‐Elvira, & Barrado, 2019).…”

“…According to the flow direction of wastewater, CWs can be mainly divided into surface flow, subsurface flow, and vertical flow CWs (Ghimire, Nandimandalam, Martinez‐Guerra, & Gude, 2019; Nivala et al, 2019; Phong Vo et al, 2019; Rabello, Teixeira, Gonçalves, & Salomão, 2019). The removal of EPs by CWs is mainly through the absorption and degradation (Li, Gao, et al, 2019; Li, Li, et al, 2019; Li, Zhang, Zeng, et al, 2019; Li, Liu, Zhang, Li, et al, 2019; Li, Zhang, Xia, Wang, et al, 2019; Li, Zhang, Hu, et al, 2019; Li, Sun, Zhang, Feng, et al, 2019; Li, Wang, et al, 2019; Li, Yuan, Gao, et al, 2019; Rabello et al, 2019). Adsorption is an important way to remove EPs, and the substrate, soil, and sediment of packed bed in CWs play major roles in adsorption (Nguyen, Chao, & Chen, 2019; Nguyen, Afzal, et al, 2019; Sardana, Cottrell, Soulsby, & Aziz, 2019; Zhao, Yan, et al, 2019; Zhao, Jian, et al, 2019).…”

The whole experiments were divided into two categories: the single adsorption of Cu 2+ by GSMM and the simultaneous adsorption of Cu 2+ and three EPs by GSMM.…”

Emerging pollutants (EPs) refer to a class of pollutants, which are emerging in the environment or recently attracted attention. EPs mainly include pharmaceutical and personal care products (PPCPs), endocrine-disrupting chemicals (EDCs), and antibiotic resistance genes (ARGs). EPs have potential threats to human health and ecological environment. In recent years, the continuous detections of EPs in surface and ground water have brought huge challenges to water treatment and also made the treatment of EPs become an international research hotspot. This paper summarizes some research results on EPs treatment published in 2019. This paper may be helpful to understand the current situations and development trends of EP treatment technologies.

Penetration of cell membrane at micro/nano-scale with untethered probe is of great scientific significance, yet still challenging. Here, a carbon nanocoil based magnetic nanorobot, which can precisely target single cell and perform cell membrane penetration, is reported. The nanorobots are as-synthesized by chemical vapor deposition with high yield, followed by physical deposition of Ni and Au nanofilms. Rotating electromagnetic fields are used to steer the nanorobots to navigate following any pre-designed path. The helical nanorobots can realize mechanical perforation of the plasma membrane and even nuclear envelope with precise position at the subcellular level. With the aid of the externally deposited Au nanofilm, surface enhanced Raman scattering bio-sensing signals can be collected from cellular plasma and nucleus. Furthermore, the nanorobots demonstrate capability of efficient photothermal therapy against targeted cancer cells and serve as an integrated theranostic platform, providing promising prospects in future precision medicine.

Fluid Field Modulation in Mass Transfer for Efficient Photocatalysis

et al. 2022

View full text Add to dashboard Cite

Mass transfer is an essential factor determining photocatalytic performance, which can be modulated by fluid field via manipulating the kinetic characteristics of photocatalysts and photocatalytic intermediates. Past decades have witnessed the efforts and achievements made in manipulating mass transfer based on photocatalyst structure and composition design, and thus, a critical survey that scrutinizes the recent progress in this topic is urgently necessitated. This review examines the basic principles of how mass transfer behavior impacts photocatalytic activity accompanying with the discussion on theoretical simulation calculation including fluid flow speed and pattern. Meanwhile, newly emerged viable photocatalytic micro/nanomotors with self‐thermophoresis, self‐diffusiophoresis, and bubble‐propulsion mechanisms as well as magnet‐actuated photocatalytic artificial cilia for facilitating mass transfer will be covered. Furthermore, their applications in photocatalytic hydrogen evolution, carbon dioxide reduction, organic pollution degradation, bacteria disinfection and so forth are scrutinized. Finally, a brief summary and future outlook are presented, providing a viable guideline to those working in photocatalysis, mass transfer, and other related fields.
