“…The LaMnO 3-δ electrode possessed the higher specific capacitance of 973.6 F g À 1 at 1 A g À 1 than that of the stoichiometric LaMnO 3 electrode (259.4 F g À 1 ) (Figure 13C). Notably, the hybrid designs composed of perovskite oxides and active materials, including Ag, [257][258][259][260] oxides, [261][262][263][264][265] carbons, [256,266] CPs, [256,267] and others, [268,269] are also an effective manner to improve capacitive performance. The examples about RE-based perovskite oxides and composites are also illustrated in Tables 6 and 7.…”

Supercapacitors (SCs) can effectively alleviate problems such as energy shortage and serious greenhouse effect. The properties of electrode materials directly affect the performance of SCs. Rare earth (RE) is known as “modern industrial vitamins”, and their functional materials have been listed as key strategic materials. In the past few years, the number of scientific reports on RE‐based nanomaterials for SCs has increased rapidly, confirming that adding RE elements or compounds to the host electrode materials with various nanostructured morphologies can greatly enhance their electrochemical performance. Although RE‐based nanomaterials have made rapid progress in SCs, there are very few works providing a comprehensive survey of this field. In view of this, a comprehensive overview of RE‐based nanomaterials for SCs is provided here, including the preparation methods, nanostructure engineering, compounds, and composites, along with their capacitance performances. The structure–activity relationships are discussed and highlighted. Meanwhile, the future challenges and perspectives are also pointed out. This Review can not only provide guidance for the further development of SCs but also arouse great interest in RE‐based nanomaterials in other research fields such as electrocatalysis, photovoltaic cells, and lithium batteries.

“…The electrical interaction is characterized by the cyclic voltammetric curves of the sensing material, which intensifies and changes its position on exposure to the analyte. Paracetamol is reported to result in oxidation peaks at −0.11 and 1.0 V jointly, with two small reduction peaks at 0.63 and 0.02 V, and glucose yielding a broad anodic peak at 0.63 V, along with cathodic reduction peak at 0.21 V. The authors have also extended the activity of the oxide to Ce-doped MnFe 2 O 4 [ 77 ] with excellent activity and one of its kind to exert the sensing activity in NaNO 3 electrolyte aided neutral media. The technique, due to its uniqueness, has attracted the possibility of being metamorphosed in nanoelectronic sensing devices.…”

“…The work was motivated by the previously noted high activity induced five successive decolourization cycles of methylene blue by MnFe 2 O 4 /ZrO 2 nanocomposite [ 57 ]. Exploring the detection capacity of paracetamol and D-glucose was also extended to doping MnFe 2 O 4 with Ce [ 77 ] which resulted in a wider range of responses over 1 to 10 mM. An excellent cyclic voltammetry validation in neutral and NaNO 3 media proves its efficiency as a candidate for electrochemical sensing.…”

Nano-enabled sensing is an expanding interdisciplinary field of emerging science with dynamic multifunctional detecting capabilities, equipped with a wide range of multi-faceted nanomaterial having diverse dimensions and composition. They have proven to be highly robust, sensitive, and useful diagnostic tools ranging from advanced industrial processes to ordinary consumer products. As no single nanomaterial has proved to be unparalleled, recent years has witnessed a large number of nanomaterial-based sensing strategies for rapid detection and quantification of processes and substances with a high degree of reliability. Nano-furnished platforms, because of easy fabrication methods and chemical versatility, can serve as ideal sensing means through different transduction mechanisms. This article, through a unified experimental-theoretical approach, uses literature of recent years to introduce, evaluate, and analyze significant developments in the area of nanotechnology-aided sensors incorporating the various classes of nanomaterial. Addressing the broad interests, the work also summarizes the sensing mechanisms using schematic illustrations, attempts to integrate the performance of different categories of nanomaterials in the design of sensors, knowledge gaps, regulatory aspects, future research directions, and challenges of implementing such techniques in standalone devices. In view of a dependency of analysis and testing on sustained growth of sensor-supported platforms, this article inspires the scientific community for more attention in this field.

The rapid urbanization and industrialization is causing worldwide water pollution, calling for advanced cleaning methods. For instance, pollutant adsorption on magnetic oxides is efficient and very practical due to the easy separation from solutions by an magnetic field. Here we review the synthesis and performance of magnetic oxides such as iron oxides, spinel ferrites, and perovskite oxides for water remediation. We present structural, optical, and magnetic properties. Magnetic oxides are also promising photocatalysts for the degradation of organic pollutants. Antimicrobial activities and adsorption of heavy metals and radionucleides are also discussed.
