“…Figure 2b reveals that MOF-5–CMC undergoes more severe losses weight, indicating that this adsorbent is less thermally stable than MOF-5. The slight loss in weight in the 31–115 °C range is attributed to volatilization of water molecules and the loss of weight observed between 256 and 464 °C is due to the cleavage of the glycosidic bonds in CMC and the loss of carbonyl and carboxyl groups during the formation of relatively low-molecular-weight volatile compounds [23,34,36]. At the same time, the organic ligands in MOF-5 thermally evaporate at 127–408 °C.…”

“…Currently, environmentally friendly high-molecular-weight carbohydrate polymers are attracting worldwide attention [20,21]. Carboxymethylcellulose (CMC) is a water-soluble anionic cellulose ether; its diverse physical and chemical properties [22] have led to its wide-ranging applications in food, medicine, and wastewater treatment [23,24]. CMC exhibits excellent compatibility with water and can form hydrogels; it is resistant to high temperatures, its structure is stable at pH 2–11, and it shows good biodegradability and affinity [25].…”

The ability to remove toxic heavy metals, such as Pb(II), from the environment is an important objective from both human-health and ecological perspectives. Herein, we describe the fabrication of a novel carboxymethylcellulose-coated metal organic material (MOF-5–CMC) adsorbent that removed lead ions from aqueous solutions. The adsorption material was characterized by Fourier-transform infrared spectroscopy, X-ray diffractometry, scanning electron microscopy, and X-ray photoelectron spectroscopy. We studied the functions of the contact time, pH, the original concentration of the Pb(II) solution, and adsorption temperature on adsorption capacity. MOF-5–CMC beads exhibit good adsorption performance; the maximum adsorption capacity obtained from the Langmuir isotherm-model is 322.58 mg/g, and the adsorption equilibrium was reached in 120 min at a concentration of 300 mg/L. The adsorption kinetics is well described by pseudo-second-order kinetics, and the adsorption equilibrium data are well fitted to the Langmuir isotherm model (R2 = 0.988). Thermodynamics experiments indicate that the adsorption process is both spontaneous and endothermic. In addition, the adsorbent is reusable. We conclude that MOF-5–CMC is a good adsorbent that can be used to remove Pb(II) from aqueous solutions.

“…Cu doping effect has been studied in catalysis, 11 sensor performance, 12,13 and in the magnetic properties of the nanomaterial. 14−16 The use of Cu as a dopant for molecular imaging is limited, with one example, in combination with Co, using nanorods for MRI 17 and one example where the 64 Cu radioisotope is used for positron emission tomography. 18 Interestingly, in both cases, the relaxometric properties of the nanomaterials make them suitable exclusively for T 2 -weighted MRI (dark contrast).…”

Synthesizing iron oxide nanoparticles for positive contrast in magnetic resonance imaging is the most promising approach to bring this nanomaterial back to the clinical field. The success of this approach depends on several aspects: the longitudinal relaxivity values, the complexity of the synthetic protocol, and the reproducibility of the synthesis. Here, we show our latest results on this goal. We have studied the effect of Cu doping on the physicochemical, magnetic, and relaxometric properties of iron oxide nanoparticles designed to provide positive contrast in magnetic resonance imaging. We have used a one-step, 10 min synthesis to produce nanoparticles with excellent colloidal stability. We have synthesized three different Cu-doped iron oxide nanoparticles showing modest to very large longitudinal relaxivity values. Finally, we have demonstrated the in vivo use of these kinds of nanoparticles both in angiography and targeted molecular imaging.

“…Spinel ferrites constitute metal oxide compounds of minute classes of transition metals that are originally obtained from magnetite (Fe 3 O 4 ). The spinel ferrites exhibit good magnetic and electrical characteristics, which has brought about its broad applications in high-density data storage, water remediation, drug delivery, sensors, spintronics, immunoassays using magnetic labeling, hyperthermia of cancer cells, optical limiting, magnetocaloric refrigeration and magnetic resonance imaging (Farid et al 2017;Dar and Varshney 2017;Amirabadizadeh et al 2017;Pour et al 2017;Alcalá et al 2017;Yan and Luo 2017;Sharma et al 2017;Winder 2016;Samoila et al 2017;Niu et al 2017;Anupama et al 2017;El Moussaoui et al 2016;Patil et al 2016;Ghafoor et al 2016;Ashour et al 2018;Amiri and Shokrollahi 2013;Ouaissa et al 2015;Houshiar et al 2014;Maksoud et al 2020a, b;Abdel Maksoud et al 2020a;Hassan et al 2019;Patil et al 2018;Žalnėravičius et al 2018;Thiesen and Jordan 2008;Koneracká et al 1999;Arruebo et al 2007;Basuki et al 2013;Gupta and Gupta 2005a, b;Jain et al 2008;Liu et al 2005;Abdel Maksoud et al 2020b). Besides these applications, raising attention in energy storage research via dissemination is due to the fast-growing demand for electronic devices that are manufactured to be smaller, lighter and relatively cheaper.…”

Advanced materials and technologies for supercapacitors used in energy conversion and storage: a review

Supercapacitors are increasingly used for energy conversion and storage systems in sustainable nanotechnologies. Graphite is a conventional electrode utilized in Li-ion-based batteries, yet its specific capacitance of 372 mA h g −1 is not adequate for supercapacitor applications. Interest in supercapacitors is due to their high-energy capacity, storage for a shorter period and longer lifetime. This review compares the following materials used to fabricate supercapacitors: spinel ferrites, e.g., MFe 2 O 4 , MMoO 4 and MCo 2 O 4 where M denotes a transition metal ion; perovskite oxides; transition metals sulfides; carbon materials; and conducting polymers. The application window of perovskite can be controlled by cations in sublattice sites. Cations increase the specific capacitance because cations possess large orbital valence electrons which grow the oxygen vacancies. Electrodes made of transition metal sulfides, e.g., ZnCo 2 S 4 , display a high specific capacitance of 1269 F g −1 , which is four times higher than those of transition metals oxides, e.g., Zn-Co ferrite, of 296 F g −1. This is explained by the low charge-transfer resistance and the high ion diffusion rate of transition metals sulfides. Composites made of magnetic oxides or transition metal sulfides with conducting polymers or carbon materials have the highest capacitance activity and cyclic stability. This is attributed to oxygen and sulfur active sites which foster electrolyte penetration during cycling, and, in turn, create new active sites.
