The CuS@reduced graphene oxide (CuS/RGO) hybrid nanocomposite was synthesized by facile hydrothermal method and used as a photoelectrode material in photovoltaic applications. In the hydrothermal route, RGO is formed by the reduction of GO with simultaneous formation of CuS/RGO nanocomposites. The CuS/RGO nanocomposites was investigated using powder XRD, TEM, HR-TEM, Raman, XPS, DRS UV–Vis spectroscopy, Photoluminescence (PL) measurements. XRD and TEM results suggest that CuS crystalline with individual spherical like homogeneous nanoparticles sizes in the range of 45–35 nm, which is distributed throughout the RGO sheets. We further construct the flexible photoelectrodes by using CuS and RGO and studied the photovoltaic performance. Photovoltaic parameters, such as short-circuit photocurrent density, open circuit voltage, fill factor and conversion efficiency were found to be 16 mA/cm2 , 0.71 V, 70.1% and 7.81% respectively, for CuS/RGO photoelectrode. The improved photo conversion efficiency of CuS/RGO is due to enhancing the electronic injection ability and reducing the photogenerated charge recombination. These photovoltaic results indicate a simple methodology for the low cost and effortless synthesis of an alternative CuS/RGO photoelectrode in high performance photovoltaic devices.

The increasing usage of composite materials has immersed simpler techniques for inspecting the integrity of composite structures, as composite materials typically have probability of getting material imperfections. In non-destructive testing, shearography reveals defects in associate object by distinguishing defect-induced deformation anomalies. Non-destructive testing (NDT) methods skit and streamer role in physical characterization of new composite materials and in assessment of their quality and serviceability in structures. Non-destructive testing (NDT), Non-destructive inspection (NDI), and Non-destructive evaluation (NDE) are concerned with the techniques and measurements that provide data on the condition of the materials and structures at the time of manufacturing and in-service.

This conceptual paper critiques the overgeneralized adoption of hybridity in translation studies, exposing its theoretical circularity, lack of actionable strategies and weak methodological grounding. Although hybridity is often conceptualized as a means of cultural negotiation, its translation-specific application remains underdeveloped. Bhabha’s “third space” metaphor is frequently cited but without translating it into actionable strategies, with existing applications being viewed either as too niche or essentializing cultural binaries. Therefore, the ethical dilemma of striking a balance between source text authenticity and target text accessibility remains unresolved, with actual translation decisions often oscillating between two extremes, either reinforcing or subverting hegemonic structures. To close this gap, this research proposes a dynamic hybrid model which puts practical strategies into action to overcome theoretical limitations of hybridity. The model draws on Joseph Malone’s practical strategies to combine foreignization and domestication in a dynamic framework which enables translators to maintain essential cultural elements while achieving clarity. The model presents a practical hybrid approach to literary translation, one that maintains a balanced harmony between faithfulness and accessibility.
