Liquid Crystals as Active Functional Media for Advanced Plasmonic Applications
(Book Rivers, 2026) Syed Salman Ahmad Warsi
Liquid crystals (LCs) have emerged as highly versatile active functional media for advanced plasmonic applications owing to their unique combination of optical anisotropy, tunability, and responsiveness to external stimuli. By integrating plasmonic nanostructures with liquid crystal matrices, dynamic control over localized surface plasmon resonances and surface plasmon polaritons can be achieved through electric, magnetic, thermal, or optical fields. This synergy enables the development of reconfigurable photonic devices with enhanced light matter interactions, improved sensing capabilities, and adaptive optical functionalities. The chapter discusses the fundamental principles governing LC plasmonic interactions, recent advances in hybrid LC plasmonic systems, and their applications in tunable sensors, optical switches, modulators, displays, and nanophotonic devices.
Introduction to Liquid Crystals: Fundamentals, Properties, and Applications
(Book Rivers, 2026) Syed Salman Ahmad Warsi
Liquid crystals are a unique state of matter that exhibit properties intermediate between conventional liquids and crystalline solids. Their ability to respond to external stimuli such as electric fields, temperature, and light has made them indispensable in modern science and technology. This chapter introduces the fundamental concepts of liquid crystals, including their historical development, molecular organization, classification, and key physical properties. Special attention is given to the major liquid crystal phases and the relationship between molecular structure and material behavior. The chapter also provides an overview of important applications of liquid crystals in displays, photonics, sensors, and advanced functional materials, highlighting their growing significance in contemporary research and technological innovations.

(Multispectrum Publications, 2026) Pranjali Tripathi, Amina Jafri, Shashank Shekhar Mishra, Deepak Yadav
This study presents a comprehensive Land Use and Land Cover (LULC) classification and agro-scientific assessment for three project sites within a 10 km buffer, representing agro-industrial, riverine, and urban-influenced landscapes. The study area contains the following land use types like agriculture, vegetation/fallow land, settlement and water bodies along with riversand. Using Sentinel-2A satellite imagery and supervised classification techniques, spatial distribution of land use categories was analyzed and quantified. The study highlights variations in agricultural potential, ecological stability, and urban pressure across the sites. Site A demonstrates strong agricultural dominance and development suitability, Site B reflects a dynamic riverine ecosystem with moderate agricultural productivity, while Site C shows significant urban influence and ecological stress. The findings highlights Agro industrial site is dominated with Agriculture with support from Vegetation & availability of perennial water bodies shows high productivity, Riverinesite being a floodplain dominated by vegetation depicts dynamic changes according to hydrological changes, good presence of riversand shows ecological sensitivity Settlement being the major land use with fragmentation of agriculture clearly depicts high anthropogenic activities low vegetation density buffering capacity near urban site and also emphasize the importance of integrating remote sensing with agro-scientific analysis for sustainable land use planning, resource management, and environmental conservation.It is evident from the study that as compared to other sites overall Agriculture is on decline more fallow land patterns can be seen with presence of Landuse conflict, River dependency for irrigation.The study of individual projects sites with other surrounding villages for comparison gives a better understanding of the environment.
Contemporary Challenges in Agroecosystems and Innovative Remediation Strategies for Sustainable Development
(Multispectrum Publications, 2026) Amina Jafri, Nida Fatma, Pranjali Tripathi
Agroecosystems, the dynamic interface between agriculture and the environment, are increasingly strained by contemporary challenges such as climate change, soil degradation, biodiversity loss, water scarcity, and the overuse of chemical inputs. These pressures threaten food security, ecosystem resilience, and the long-term viability of agricultural practices. Addressing these issues requires a paradigm shift toward sustainable development that integrates ecological balance with socio-economic progress. Innovative remediation strategies ranging from precision agriculture, biofertilizers, and phytoremediation to regenerative farming, circular resource management, and digital technologies offer promising pathways to restore ecosystem health while enhancing productivity. This paper explores the multifaceted challenges confronting agroecosystems and evaluates cutting-edge solutions that align with the principles of sustainability. By synthesizing scientific insights and practical approaches, it underscores the importance of holistic, adaptive, and inclusive strategies to ensure resilient agroecosystems capable of meeting global food demands without compromising environmental integrity.
