Chapter “Eco-friendly Surface Modification and Nanofinishing of Textile
Polymers to Enhance Functionalisation” gives brief information about the application of non-thermal atmospheric pressure plasma and nanotechnology in the
fields of textiles. The chapter reviews the recent studies involving modification and
characterisation of textile highlighting plasma and nano pretreatment. This chapter
also attempts to give an overview of the literature on treatment of textiles categorizing them on the basis of different functional properties like antimicrobial, UV
resistance, easy care, dye adsorption, and flame-retardant finishes that could be
achieved by the application of metal and metal oxide nanoparticles and enhanced by
plasma pretreatment.
Chapter “Removal of Ni(II) and Zn(II) from Aqueous Media Using AlgaeSodium Bentonite Nanocomposite” enlightens the utilization composite, made by
mixing dead Spirogyra algal biomass with nano-bentonite clay, to study the
adsorption of Ni(II) and Zn(II) as a function of pH, contact time, adsorbent dosage,
and initial ion concentration. An average crystal size of the composite synthesized
was found to be 34.11 nm. Langmuir adsorption isotherm and pseudo-second-order
models were found to be the best fit for equilibrium data, highlighting the potential
of algae bentonite composite as possible feedstock for adsorption of heavy metals
from aqueous media.
Chapter “Nucleic Acid Based Nanoconstructs for Environmental Analysis in
Atypical Contexts” highlights the use of biomolecules toward environmental
analysis that provides impressive advantages in terms of selectivity and efficiency.
A proof-of-concept of nucleic acid based nanoconstructs as a reusable adsorbing
agent is presented in the chapter. Immobilization of the nucleic acid architectures on
magnetic nanoparticles enables their reuse across samples. Inherent sophistication
of biomolecules in general and nucleic acid based constructs in particular supports
their deployment in specialized applications at a smaller scale pertinent to individual human activity. The perspective presented in this chapter is expected to
encourage environmental engineering in distinctive and atypical contexts.
We would wish to convey our gratitude to all authors for their significant
contribution in the form of chapters for this book. We also acknowledge the support
provided by Neeraj Gaur and our doctoral students (Gomathi, Umasankar, Rohan,
Shruti, Mona, Mumal, and Priyanka) during the process. The support provided by
family members is immense without which the book could not have seen the light
of the day. Our special thanks to Springer Publication team especially Renette
Francis Irine and Charlotte Cross for their constant cooperation.
