“…As expected, the untreated metal surfaces have almost no absorption in the IR region, but a weak band around 1400 cm −1 was detected on AZ31, which can be related to some carbonates on the surface of the alloy [31]. After the coating formation, the typical fingerprint of tannic acid can be observed in the spectra, with the bands rising from the vibrational mode of phenolic OH (the halo at 3300 cm −1 ), C=O (at 1700 cm −1 ), aromatic rings (1700-1400 cm −1 ), COOH (1400-1200 cm −1 ), and C-O (1200-1000 cm −1 ) [32][33][34]. The higher intensity of the organic peaks on the AZ31TA_20 with respect to the AZ91TA is related to more intimate contact between the sample and the ATR crystal, due to the lower roughness of the AZ31 samples, which results in better signal detection.…”

Magnesium alloys are promising materials for bioresorbable implants that will improve patient life and reduce healthcare costs. However, their clinical use is prevented by the rapid degradation and corrosion of magnesium, which leads to a fast loss of mechanical strength and the formation of by-products that can trigger tissue inflammation. Here, a tannic acid coating is proposed to control the degradation of AZ31 and AZ91 alloys, starting from a previous study by the authors on AZ91. The coatings on the two materials were characterized both by the chemical (EDS, FTIR, XPS) and the morphological (SEM, confocal profilometry) point of view. Static degradation tests in PBS and electrochemical measurements in different solutions showed that the protective performances of the tannic acid coatings are strongly affected by the presence of cracks. The presence of fractures in the protective layer generates galvanic couples between the coating scales and the metal, worsening the corrosion resistance. Although degradation control was not achieved, useful insights on the degradation mechanisms of coated Mg surfaces were obtained, as well as key points for future studies: it resulted that the absence of cracks in protective coatings is of uttermost importance for novel biodegradable implants with proper degradation kinetics.

“…They are usually pure materials that can be tuned to obtain the desired composition and stimuli-responsiveness [ 3 ]. Water treatment [ 4 ], dyes and metal adsorption [ 5 ], drug delivery [ 6 ], actuators and sensors [ 7 , 8 ], biomedical engineering [ 9 ], and energy storage [ 10 ] all use radiation-induced hydrogels extensively. Purification is a pressing issue worldwide due to the various sources of pollutants that impact livestock.…”

Along with serving as drug delivery sensors and flexible devices, hydrogels are playing pioneering roles in water purification. Both chemical and radiation methods can produce hydrogels, with the latter method gaining preference for its pure adducts. The water treatment process entails the removal of heavy and toxic metals (above the threshold amount), dyes, and solid wastes from industrial effluents, seawater, and groundwater, as well as sterilization for microorganism destruction. This review analyzed the different types of hydrogels produced by applying various radiations for water treatment. Particularly, we examined the hydrogels created through the application of varying levels of gamma and electron beam radiation from the electron gun and Co-60 sources. Moreover, we discuss the optimized radiation doses, the compositions (monomers and polymers) of raw materials required for hydrogel preparation, and their performance in water purification. We present and predict the current state and future possibilities of radiation-induced hydrogels. We explain and compare the superiority of one radiation method over other radiation methods (UV-visible, X-ray, microwave, etc.) based on water treatment.

“…Dave et al described a thymine‐rich DNA functionalized polyacrylamide hydrogel‐based Hg 2+ sensor (Dave et al, 2010). Although a number of studies demonstrated hydrogels as Hg 2+ sensor, but in literature, it was also shown that these hydrogels are not selective towards only Hg 2+ (El‐damhougy et al, 2021; Hong et al, 2011) and was in need of sophisticated systems, costly reagents and also lacked online monitoring, which was a disadvantage. Hence, it was thus important for the development of novel materials and approaches to selectively sensing of Hg 2+ in aquatic environment.…”

Here, we demonstrated the use of 3‐mercaptopropionic acid‐capped CdSe quantum dots (CdSe QDs) for the sensing of mercury ions (Hg2+) in solution. The size and the shape of the synthesized QD were observed through transmission electron microscopy (TEM), and crystallinity was confirmed through X‐ray diffraction (XRD) analysis. The synthesized QD showed to have mean size 4 nm. Our QD was found to sense Hg2+ ions with a detection limit of 5 ppm at pH 7.0 and a linearity range of 5–50 ppm. The effect of pH on the optical property of QD was also investigated and found that the sensor worked best at pH 7.0 with high linearity and sensitivity, thus reducing the cost of the process. The sensing mechanism of CdSe QD was further analysed through Fourier transform infrared (FTIR) spectroscopy. Therefore, our synthesized CdSe QD capped with 3‐mercaptopropionic acid demonstrated to act as an efficient nanomaterial for rapid and easy to perform sensing of mercury ion in aquatic environment.
