Advances in airborne microorganisms detection using biosensors: A critical review

Frontiers of Environmental Science & Engineering 2021, Volume 15, Issue 3, doi: 10.1007/s11783-021-1420-8

Abstract:

Humanity has been facing the threat of a variety of infectious diseases. Airborne microorganisms can cause airborne infectious diseases, which spread rapidly and extensively, causing huge losses to human society on a global scale. In recent years, the detection technology for airborne microorganisms has developed rapidly; it can be roughly divided into biochemical, immune, and molecular technologies.

Effects of preparation methods on the activity of CuO/CeO

Huanhuan Shang, Xiaoman Zhang, Jing Xu, Yifan Han

Frontiers of Chemical Science and Engineering 2017, Volume 11, Issue 4,   Pages 603-612 doi: 10.1007/s11705-017-1661-z

Abstract: CO oxidation has been investigated on three CuO/CeO catalysts prepared by impregnation, co-precipitation and mechanical mixing. The origin of active sites was explored by the multiple techniques. The catalyst prepared by impregnation has more highly dispersed CuO and stronger interactions between CuO and CeO to promote the reduction of CuO to Cu species at the Cu-Ce interface, leading to its highest catalytic activity. For the catalyst prepared by co-precipitation, solid solution structures observed in Raman spectra suppress the formation of the Cu-Ce interface, where the adsorbed CO will react with active lattice oxygen to form CO , and thus it displays a lower catalytic performance. No Cu-Ce interface exists in the catalyst prepared by the mechanical mixing method due to the separate phases of CuO and CeO , resulting in its lowest activity among the three catalysts.

Influence of surface modified mixed metal oxide nanoparticles on the electrochemical and mechanical properties of polyurethane matrix

Frontiers of Chemical Science and Engineering 2023, Volume 17, Issue 1,   Pages 1-14 doi: 10.1007/s11705-022-2176-9

Abstract: Newly synthesized functional nanoparticles, 3-amino-1,2,4-triazole (ATA)/SiO2–TiO2 were introduced to the polyurethane (PU) matrix. Electrochemical techniques were used to investigate the barrier properties of the synthesized PU–ATA/SiO2–TiO2 nanocomposite coated steel specimen. In natural seawater, electrochemical impedance spectroscopy experiments indicated outstanding protective behaviour for the PU–ATA/SiO2–TiO2 coated steel. The coating resistance (Rcoat) of PU–ATA/SiO2–TiO2 was determined to be 2956.90 kΩ·cm–2. The Rcoat of the PU–ATA/SiO2–TiO2 nanocomposite coating was found to be over 50% higher than the PU coating. The current measured along the scratched surface of the PU–ATA/SiO2–TiO2 coating was found to be very low (1.65 nA). The enhanced ATA/SiO2–TiO2 nanoparticles inhibited the entry of electrolytes into the coating interface, as revealed by scanning electron microscopy/energy dispersive X-ray spectroscopy and X-ray diffraction analysis of the degradation products. Water contact angle testing validated the hydrophobic nature of the PU–ATA/SiO2–TiO2 coating (θ = 115.4°). When the concentration of ATA/SiO2−TiO2 nanoparticles was 2 wt %, dynamic mechanical analysis revealed better mechanical properties. Therefore, the newly synthesised PU–ATA/SiO2–TiO2 nanocomposite provided excellent barrier and mechanical properties due to the addition of ATA/SiO2–TiO2 nanoparticles to the polyurethane, which inhibited material degradation and aided in the prolongation of the coated steel’s life.

Recent development and application of thin-film thermoelectric cooler

Yuedong Yu, Wei Zhu, Xixia Kong, Yaling Wang, Pengcheng Zhu, Yuan Deng

Frontiers of Chemical Science and Engineering 2020, Volume 14, Issue 4,   Pages 492-503 doi: 10.1007/s11705-019-1829-9

Abstract: Recently, the performance and fabrication of thin-film thermoelectric materials have been largely enhanced. Based on this enhancement, the thin-film thermoelectric cooler (TEC) is becoming a research hot topic, due to its high cooling flux and microchip level size. To fulfill a thin-film TEC, interfacial problems are unavoidable, as they may largely reduce the properties of a thin-film TEC. Moreover, the architecture of a thin-film TEC should also be properly designed. In this review, we introduced the enhancement of thermoelectric properties of (Bi,Sb) (Te,Se) solid solution materials by chemical vapor deposition, physical vapor deposition and electrodeposition. Then, the interfacial problems, including contact resistance, interfacial diffusion and thermal contact resistance, were discussed. Furthermore, the design, fabrication, as well as the performance of thin-film TECs were summarized.

Unraveling Membrane Fouling Induced by Chlorinated Water Versus Surface Water: Biofouling Properties and Microbiological Article

Li Zhang, Lei Xu, Nigel Graham, Wenzheng Yu,

Engineering 2022, Volume 15, Issue 8,   Pages 154-164 doi: 10.1016/j.eng.2021.03.016

Abstract:

Chlorine is usually applied in the process of urban water treatment to deactivate pathogens and prevent waterborne diseases. As a pre-treatment during water treatment, it remains unclear whether chlorinated water can effectively alleviate the fouling of membranes during ultrafiltration (UF). In this study, tap water was investigated with respect to its impacts on biofilm formation and biofouling in a gravity-driven membrane (GDM) filtration system. For comparison, the biofilm/biofouling with untreated surface (lake) water was studied in parallel. It was found that more severe membrane fouling occurred with the filtration of tap water than lake water, and larger quantities of polysaccharide and eDNA were present in the tap-water biofilm than in lake-water biofilm. The tap-water biofilm had a densely compact morphology, whereas a porous, spider-like structure was observed for the lake-water biofilm, which was assumed to be associated with the bacteria in the biofilm. The hypothesis was verified by the 16S ribosomal RNA (rRNA) sequencing results which demonstrated that Xanthobacter was the dominant taxon in the tap-water biofilm. Additionally, membrane hydrophobicity/hydrophilicity played a minor role in affecting the membrane fouling properties and microbial community. Overall, these findings have revealed the significant role of chlorine-resistant bacteria in biofouling formation and provided a deeper understanding of membrane fouling, which can potentially aid the search for effective ways of controlling membrane fouling.

Host–Guest Molecular Recognition at Liquid–Liquid Interfaces Review

Beibei Wang, Hao Chen, Tan Liu, Shaowei Shi, Thomas P. Russell

Engineering 2021, Volume 7, Issue 5,   Pages 603-614 doi: 10.1016/j.eng.2021.02.004

Abstract:

Host–guest molecular recognition at the liquid–liquid interface endows the interface with unique properties, including stimuli-responsiveness and self-regulation, due to the dynamic and reversible nature of non-covalent interactions. Increasing research efforts have been put into the preparation of supramolecular interfacial systems such as films and microcapsules by integrating functional components (e.g., colloidal particles, polymers) at the interface, providing tremendous opportunities in the areas of encapsulation, delivery vehicles, and biphasic reaction systems. In this review, we summarize recent progress in supramolecular interfacial systems assembled by host–guest chemistry, and provide an overview of the fabrication process, functions, and promising applications of the resultant constructs.
