“…As seen in the figure, the I D / I G ratio of N-pCs increased for MoO 3 ( I D / I G = 0.95) and MoS 2 ( I D / I G = 1.1) incorporated ones, indicating an increased structural defects and simultaneously decreased graphitization degree of carbonaceous structures during the stepwise procedure . As represented in the Raman spectra of MoO 3 /N-pCs, the peaks that are located at 252, 286, 666, (∼831–861), and 942 cm –1 can be attributed to the twisting and wagging of OMO, bending, scissoring, asymmetrical stretching of O–M–O, symmetrical, and asymmetrical stretching vibrations of MO. , The diffraction peaks observed in the spectra of MoS 2 /S,N-pCs are well-matched with the hexagonal MoS 2 layered morphology, in which the characteristic bands located at 367 and 401 cm –1 correspond to the 1 E 2g and A 1g vibration modes . Taking on a pivotal role in the capacitive performance of the prepared electrode active materials, their SSA and pore size distribution were further investigated through a nitrogen adsorption–desorption technique and are represented in the Supporting Information (S4) and in (Figure S3a,b).…”

In parallel to the depletion of potable water reservoirs, novel technologies have been developed for seawater softening, as it is the most abundant source for generating deionized water. Although salt removal at subosmotic pressures and ambient temperatures by applying low-operating potentials with high energy efficiency made capacitive deionization (CDI) an advantageous water-softening process, its practical application is limited by insufficient ion removal capacity and low concentration influent. The performance of a CDI system is in progress with engineering the electrode active materials, also facilitating the advance design in highly saline-and seawater study. Herein, an innovative strategy was developed to provide high-performance CDI systems based on efficient and electrochemical ion-uptake active materials with a simple initial preparation. Nitrogen-doped porous carbons (N-pCs) received benefits from a high specific surface area and good surface wettability. The N-pCs were modified with molybdenum oxide/sulfide intercalative array and developed as CDI electrode active materials for desalination of both low/medium saline-and seawater. The MoS 2 /S,N-pC electrode materials exhibited perfect optimized salt adsorption capacity (SACs) of 47.9 mg g −1 when compared to N-pC (37.9 mg g −1 ) and MoO 3 /N-pC (39.6 mg g −1 ) counterparts at 1.4 V in a 750 ppm NaCl solution. In addition, the assembled CDI cells exhibited reasonable cycle stability and retained 96.7% of their initial SAC in continuous CDI cycles for 128,000 s. The fabricated CDI cell rendered an excellent salt removal efficiency (SRE, %) of 13.34% from the real seawater sample at 1.2 V. In detail, the SRE % of the NaCl, KCl, MgCl 2 , and CaCl 2 soluble salts with respect to seawater sample exhibited a remarkable SRE % of 30.8%, 36%, 32.6%, and 19.3%, respectively. These SRE % values (>13.34%) provide convincing evidence on the reasonable ion uptake capability of the fabricated CDI cells for removing Na + , K + , Mg 2+ , and Ca 2+ ions compared to other soluble component. The advanced cell design parallel to the promising outcomes provided herein makes these CDI systems immensely propitious for efficient water softening.

Interleukins (ILs) are a major subclass of cytokines which act as molecular messengers playing a role in immune system responses via cascade of signalling pathways. Belonging to the cytokine family, ILs play a crucial role in the theronostics of various diseases. Their abnormal expression leads to development of various diseases such as cancer, neurodegenerative diseases, allergies, asthma, autoimmune diseases, and other physiological abnormalities. This paves the way for exploring ILs to develop sensitive and efficient biosensors, and promoting them for clinical testing in a wide array of diseases. Furthermore, detecting the level of ILs is very important for their early diagnosis and their progression within the body, and simultaneously for possible immunotherapeutic approaches. To achieve this goal, multidisciplinary scientific approaches involving immunology, electrochemistry, nanotechnology, photometry, etc. are already being put into action. Advancements in nanoscience and nanotechnology are aiding in the development of highly sensitive biosensors for ILs detection. This review focuses on a detailed description of all presently discovered ILs and their roles in various diseases. Simultaneously, it also discusses the various electrochemical biosensors that can be employed for the detection of ILs in bodily fluids. Moreover, the role of nanomaterials in electrochemical biosensing are also discussed here.
