In the last several decades, there has been significant growth in research and development activities in nanomaterials. Nanotech has been used to improve the quality of several materials, including wood and polymer composites, for their application in various fields. Nanofillers, including metal particles, nano oxides, pyrogenic silica, and carbon black, have been employed as polymer additives. However, the value of natural, low-cost, and plentiful clay materials such as nanoclay becomes more apparent as environmental regulations and consumer awareness become more rigorous. This literature outlines the role of nanoclay on polymer composites, especially in the case of thermosetting resins, including epoxy, polyester, urea-formaldehyde, and phenol-formaldehyde resins. The current article is intended to provide a comprehensive source of recent studies and literature on nanoclay as filler, its classification, polymer modification processes using nanoclay, and comparing the performance of different thermosetting polymers based on their fabrication methods through physical and mechanical properties.

• Organic farming grapples with drought, demanding efficient crop selection. • Molecular techniques revolutionize selection, expediting drought-resistant crop identification. • This review delves into molecular tech's role in streamlining drought-resistant crop selection in organic agriculture. • This exploration guides towards drought-resistant crop varieties, promoting sustainability amidst climate unpredictability. Drought, an ever-looming threat to agriculture, is of paramount concern in organic crop production. The traditional methodologies employed for screening and selecting drought-resistant crops are characterized by their laborious and time-intensive nature. However, the integration of molecular techniques has wrought a revolutionary transformation, expediting the identification and precise selection of crop varieties resilient to drought stress. This review explores the intricate relationship between molecular technologies and the imperative to streamline the screening and selection process for drought-resistant crops in organic agriculture. The advantages of these molecular methodologies are delved into, revealing the potential to accelerate the breeding of crops capable of withstanding the challenges posed by water scarcity. However, this exploration is full of challenges. From scalability issues to cost-effectiveness, ethical implications, and environmental impact, a comprehensive examination is crucial for a nuanced understanding of integrating these technologies into the organic crop production landscape. Moreover, this review extends beyond the present, casting a discerning eye toward the prospects of molecular techniques in pursuing sustainable agriculture. The potential for refinement, overcoming challenges, and synergies with other emerging technologies is crucially considered as a resilient and environmentally conscious agricultural future is envisioned. In essence, this exploration serves as a comprehensive guide, shedding light on the transformative power of molecular techniques in navigating the intricate path towards drought-resistant crop varieties, thereby fostering sustainable practices in the face of an increasingly unpredictable climate.
