Abstract

Large language models (LLMs) have transformed natural language processing (NLP), demonstrating exceptional proficiency in tasks such as text generation, translation, and summarization. However, LLMs are prone to generating biased, inaccurate, or contextually irrelevant outputs, posing significant risks in high-stakes domains such as healthcare, legal reasoning, and engineering. This paper systematically investigates the role of prompt engineering as a solution to these challenges. By strategically designing inputs, prompt engineering enhances LLM performance, yielding more accurate, contextually relevant, and ethically aligned outputs. Advanced techniques, including chain-of-thought (CoT) prompting and retrieval augmented generation (RAG), are examined for their ability to improve reasoning capabilities, reduce errors, and mitigate bias. CoT prompting facilitates structured, stepwise reasoning, while RAG incorporates real-time data, ensuring output accuracy in rapidly evolving fields. In addition, we present a novel comparative perspective on these techniques, highlighting their distinct strengths and limitations across specialized applications such as healthcare diagnostics and scientific data extraction. The findings demonstrate that sophisticated prompt engineering significantly elevates the reliability and precision of LLM outputs, while addressing critical ethical concerns such as data privacy, bias, and hallucination. These insights underscore the necessity of advanced prompt design in optimizing LLMs for high-impact applications, ensuring both performance and ethical integrity.

Abstract

This study examines the integration of nanotechnology into chemical engineering education and its implications for future curriculum development. A bibliometric and technological review was conducted using publications from major scientific databases, with standardized datasets and mapped collaboration and keyword networks to identify pedagogical and curricular trends. The findings indicate a steady growth of interdisciplinary research linking nanoscale concepts with process engineering, accompanied by increasing adoption of virtual laboratories, computer simulations, and intelligent tutoring systems. Nevertheless, challenges remain, including uneven faculty preparedness, limited access to advanced instrumentation, and the lack of unified competency frameworks across institutions. These constraints are largely driven by macro-centric teaching traditions, resource limitations, and inconsistent curriculum standards. To address these gaps, the study proposes targeted updates to core and elective courses that emphasize nano-centric content, sustainability, and digital pedagogy. Overall, the paper presents a practical framework aligned with Safe-by-Design principles and the United Nations Sustainable Development Goals.
