Ru-dye grafted cus and reduced graphene oxide (cus/rgo)composite:an efficient and photo tunable electrode for dye sensitized solar cells

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.

Review on non-destructive testing of composite materials in aircraft applications

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.

Reconceiving translation: homi bhabha's hybridity and the third space in literary translation

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.

Mastering the art of efficient literature reviews: a practical guide for medical professionals and students

The exponential growth of biomedical literature presents both an unprecedented opportunity and a significant challenge for medical professionals and students. Conducting a thorough yet efficient literature review is a fundamental skill, essential for evidence-based practice (EBP), research, education, and scholarly writing. However, navigating this vast information landscape effectively remains a common hurdle. This review aims to provide a comprehensive, step-by-step guide to conducting efficient and rigorous literature reviews tailored to the needs of medical professionals and students. It focuses on practical strategies, critical appraisal techniques, synthesis methods, and leveraging technology to optimize the process while maintaining scientific integrity. A narrative review methodology was employed, synthesizing established principles and methods from evidence-based medicine, information science, and academic writing. Key sources include guidelines from major medical libraries, EBP resources, and authoritative texts on research methodology and critical appraisal. The review outlines a structured approach encompassing: defining a focused question using frameworks like Participants; Intervention/Exposure; Comparison; and Outcome (PICO/PECO); developing and executing a systematic search strategy across multiple databases; efficient screening and selection of relevant literature; critical appraisal of study quality and relevance; effective synthesis of findings (narrative, thematic, or tabular); clear and concise writing; and strategies for maintaining currency. Emphasis is placed on leveraging technology (reference managers, databases, and AI tools) cautiously and avoiding common pitfalls, such as scope creep and uncritical acceptance of findings. A life-long experience that the academic writer learns through life, and yet may fall into them easily. An efficient literature review is not merely about speed, but about systematic rigor, critical thinking, and strategic use of resources. By adopting the structured, technology-enhanced, and critically appraised approach outlined, medical professionals and students can navigate the literature effectively, saving valuable time while producing high-quality, evidence-informed outputs for clinical practice, research, and education.

Dunbar syndrome – a narrative review

Dunbar syndrome (DS) is a rare condition, predominantly in females. It arises due to the compression of the celiac trunk and celiac plexus by the fibrous attachments of the median arcuate ligament of the diaphragm. DS mimics many common gastrointestinal disorders due to the postprandial nature of symptoms and is technically a diagnosis of exclusion, confirmed by various imaging modalities. The goal of treatment is decompression of the celiac trunk, and surgery is either the mainstay of therapy, along with adjuvant interventional procedures like percutaneous transluminal angioplasty and stenting. In this review article, we revisit DS to enhance awareness among healthcare providers and discuss this disorder in terms of its historical background, epidemiology, etiopathogenesis, clinical presentation, diagnosis, and management.
