“…Moreover, the specific surface areas and pore size N 2 adsorption–desorption isotherms of the fabricated samples were investigated, and the results given in Figure show that all of the photocatalysts presented type IV hysteresis loops according to the Brunauer–Deming–Deming–Teller classification . The calculated specific surface area, pore diameter, and pore volume are also displayed in Table , and the results show that the synthesized g-C 3 N 4 @Cs 0.33 WO 3 heterojunction presented the highest specific surface area of 51.74 m 2 /g as compared to those of the bare materials Cs 0.33 WO 3 and g-C 3 N 4 .…”

“…Therefore, the design and selection of suitable materials to form heterostructures that can absorb full-spectrum solar light are necessary. Interestingly, tungsten bronze based materials M x WO 3 (0 < x < 1, M = Cs, Rb, K, Na, Li) are suitable candidates for this purpose due to their excellent NIR and UV light absorption properties. , In particular, Cs 0.33 WO 3 has attracted attention in various fields, such as water evaporation, photocatalysis, gas sensors, smart window coatings, and photothermal ablation cancer treatments, , due to its outstanding NIR light absorption property. The mixed-valence W 5+ and W 6+ as well as large oxygen vacancies make cesium tungsten oxide a suitable material for photocatalysis.…”

This study facilitates the synthesis of a graphitic carbon nitride/cesium tungsten oxide (g-C3N4@Cs0.33WO3) heterojunction using a solvothermal method. The photocatalytic activities of the prepared samples were examined for the photodegradation of colorless antibiotics, namely tetracycline, enrofloxacin, and ciprofloxacin, as well as cationic and anionic dyes, such as methyl orange, rhodamine B, neutral red, and methylene blue, under full-spectrum solar light. We have purposely selected different kinds of wastewater pollutants of colorless antibiotics and cationic and anionic organic dyes to investigate the potential application of this heterojunction toward different groups of water pollutants. The results revealed that the g-C3N4@Cs0.33WO3 heterojunction showed an outstanding photocatalytic activity toward all the pollutants with concentrations of 20 ppm each at pH 3 by photocatalytically removing 97% of tetracycline within 3 h, 98% of enrofloxacin within 2 h, 97% of ciprofloxacin within 2.25 h, 98% of methylene blue in 1 h, 99% of rhodamine B within 2 h, 99% of neutral red in 1.25 h, and 95% of methyl orange in 2 h. These findings indicate that the developed photocatalyst possesses excellent photocatalytic properties toward seven different water pollutants that make it a universal photocatalyst. The developed g-C3N4@Cs0.33WO3 oxide heterojunction also presented a photocatalytic performance better than those of reported solar light active photocatalysts for photodegradation of rhodamine B and tetracycline. The efficient photocatalytic performance of the heterojunction can be ascribed to its extended light-absorbing ability, effective charge separation and fast charge transfer properties, and a high surface area. Moreover, an active species detection experiment also confirmed that superoxide radicals, hydroxyl radicals, and holes played significant roles in the photocatalysis of the organic dyes and tetracycline.

In recent decades, the rising frequency of infectious illnesses has presented a severe danger to public health. The Centres for Disease Control and Prevention (CDC) in the United States established that an infected or asymptomatic person wearing a surgical mask shields others from the user. This is because virus-laden aerosols and droplets are thought to be the major mode of transmission between persons. The United States continues to have insufficient control over the spread of SARS-CoV-2, even with the extensive use of masks and other mitigating methods. The public health viewpoint on mask usage, the technical specifications of store-bought and homemade masks, and the most current developments in mask engineering, materials, and disinfection will all be covered in this review. Additionally, the sustainability of mask wear and mask manufacture will be discussed.

Cracks formed in materials can influence the performances and shorten their lifetime. Self‐healing materials can repair cracks caused by mechanical damage using external stimuli, which increases their safety, extend their service life, and can save renovation costs. In this work, a novel thermo‐responsive linear Diels‐Alder polyurethane (DAPU) and reduced tungsten oxide (WO3−x) (W‐DAPU) is developed for the first time. Its near‐infrared (NIR) light‐induced self‐healing properties are evaluated using qualitative optical observation and quantitative tensile measurements. The NIR light‐induced self‐healing and photothermal conversion property of W‐DAPU is also systematically investigated. The results show that linear DAPU has an excellent thermo‐reversible self‐healing efficiency of 94.8% and heals within 6 s due to the presence of a DA bond. In addition, the W‐DAPU has a self‐healing efficiency of 83.2% with outstanding photothermal conversion. This study paves the way to design and fabricate stimuli‐responsive nanocomposite materials for various applications.
