While the standard dichotomic noise model offers exact solutions that capture non-Markovian dynamics, it violates detailed balance and fails to ensure thermal equilibrium. To overcome this, we introduce a temperature-corrected version by adding a counterterm to the exact equations of motion, thereby restoring the correct equilibrium behavior. Furthermore, we explore the TLS dynamics under varying initial conditions and parameter regimes. The results demonstrate that the model reproduces both short-time coherent evolution and long-time thermal populations and captures single-system behavior relevant to experiments on isolated quantum systems.

Interestingly, photocatalytic degradation employing nanoarchitecture materials has emerged as a cutting-edge technique for cleaning up these aquatic contaminants. The goal of this work is to review the remediation of OSSC through photocatalytic degradation-oriented technology and holistically evaluate the performance of various nanoarchitecture materials. As part of the novelty to demonstrate the pilot/industrial-scale potential and eco-economic benefits of this strategy, this work reviews recyclability and real-life application studies, which are sometimes overlooked. Also, this work reviews the effect of radical scavengers and electron trapping studies to clarify the process of OSSC photocatalytic degradation. Remarkably, it was discovered that various nanomaterials can deliver over 70%–100% degradation efficiency in 4–540 min. Additionally, the electron trapping studies revealed that the primary radicals in charge of photocatalytic degradation activities are ˙O<sub>2</sub><sup>−</sup> and ˙OH. The findings also showed that different nanomaterials may be reused 2–10 times while maintaining >70% of the initial efficiency.

The CuO-C/NiCo<sub>2</sub>O<sub>4</sub>/GCE composite electrode was acquired by embellishing CuO-C/NiCo<sub>2</sub>O<sub>4</sub> on polished glassy carbon electrodes (GCE) using dropwise coating. The synthesized CuO-C/NiCo<sub>2</sub>O<sub>4</sub> was investigated through: (i) scanning electron microscopy (SEM) imaging for morphological evaluation, (ii) X-ray diffraction (XRD) for phase identification, and (iii) X-ray photoelectron spectroscopy (XPS) for elemental state determination. The results revealed that the CuO-C/NiCo₂O₄ composites have a loose and porous surface, an elevated active surface area, high electrical conductivity, and electrocatalytic properties. Based on this result, an electrochemically novel sensor for the detection of quercetin using CuO-C/NiCo₂O₄ composites was developed. The sensor displayed high reproducibility, redox stability, and anti-interference capability in the detection of quercetin. In addition, the peak current measured by this sensor was linearly correlated with the density of quercetin, exhibiting a wide linearity response from 0.1 to 20 μM with an ultralow detection limit of 0.092 μM.
