“…As the LiL content increases, the decrease in D values may be due to the increase of FWHMs (as seen in Table ); in other words, the broadening of the dominant XRD peak shapes. Also, this decrease may be due to the increase in crystal lattice distortions after nucleation during the crystallization process with increasing LiL concentration in the solution. − …”

Enhanced sweat sensors lead to real-time, sustained, noninvasive tracking of sweat loss, ensure insight into individual health conditions at the molecular level, and have obtained prominent interest for their hopeful implementations in customized health tracking. Metal-oxide-based nanostructured electrochemical amperometric sensing materials are the best selection for continuous sweat monitoring devices owing to their high stability, high-sensing capacity, cost-effectiveness, miniaturization, and wide applicability. In this research, CuO thin films have been fabricated by successive ionic layer adsorption and reaction technique (SILAR) with and without the addition of Lawsonia inermis L. (Henna, (LiL)) leaf extract (C10H6O3, 2-hydroxy-1,4-naphthoquinone) with a high-sensitive and rapid response for sweat solution. Despite the pristine film being responsive to the 65.50 mM sweat solution (S = 2.66), the response characteristic improves to 3.95 for the 1.0% LiL-implemented CuO film. Unmodified, 1.0% LiL and 3.0% LiL-substituted thin-film materials assure considerable linearity with linear regression ranges, R 2, of 0.989, 0.997, and 0.998, respectively. It is noteworthy here that this research aims to determine an enhanced system that could potentially be implemented in real-life sweat-tracking administrations. Real-time sweat loss tracking capabilities of CuO samples was found to be promising. Derived from these outcomes, we concluded that the fabricated nanostructured CuO-based sensing system is a useful application for the continuous observation of sweat loss as a biological argument and compatibility with other microelectronic technologies.

Graphitic carbon nitride (g‐C3N4) has been extensively doped with alkali metals to enlarge photocatalytic output, in which cesium (Cs) doping is predicted to be the most efficient. Nevertheless, the sluggish diffusion and doping kinetics of precursors with high melting points, along with imprecise regulation, have raised the debate on whether Cs doping could make sense. For this matter, we attempt to confirm the positive effects of Cs doping on multifunctional photocatalysis by first using cesium acetate with the character of easy manipulation. The optimized Cs‐doped g‐C3N4 (CCN) shows a 41.6‐fold increase in visible‐light‐driven hydrogen evolution reaction (HER) compared to pure g‐C3N4 and impressive degradation capability, especially with 77% refractory tetracycline and almost 100% rhodamine B degraded within an hour. The penetration of Cs+ is demonstrated to be a mode of interlayer doping, and Cs–N bonds (especially with sp2 pyridine N in C═N–C), along with robust chemical interaction and electron exchange, are fabricated. This atomic configuration triggers the broadened spectral response, the improved charge migration, and the activated photocatalytic capacity. Furthermore, we evaluate the CCN/cadmium sulfide hybrid as a Z‐scheme configuration, promoting the visible HER yield to 9.02 mmol g−1 h−1, which is the highest ever reported among all CCN systems. This work adds to the rapidly expanding field of manipulation strategies and supports further development of mediating served for photocatalysis.

“…Heavily Ru-doped CuO shows superconducting features, 47 while forming complex compounds of nanostructured CuO with magnetic ions can introduce ferromagnetic ordering. 48 Dielectric analysis is a critical and valuable tool for understanding ion transport behaviour in ionic conductors. The dielectric study provides adequate information on the translational and orientational movement of mobile charge carriers in dielectric systems.…”
