speed (2000–3000 rpm), and annealing temperature (60–100°C). The dependent
parameter considered in this study is power conversion efficiency (PCE) of perovskite solar cell (PSC) fabricated using MAPbI 3 layer.
Chapter “Application of Nanotechnology in Diagnosis and Therapeutics”
emphasizes on the evolution of nanoparticles to meet the challenges relevant to
healthcare system. In terms of human healthcare and therapy, nanoparticles are
expected to contribute in drug delivery and regenerative medicine with its ability to
target the source of disease with increased efficiency and minimal side effects.
Nanomedicine offers several advantages, such as protection of the payload from
degradation in both in vitro and in vivo milieu, facilitation of controlled release of
entrapped drugs, prolonged therapeutic effect, and enhancement of targeted delivery
along with diminished side effects. Nanotechnology has proved to address some
of the problems related to diagnostics, therapeutics, and biomedical aspects.
Chapter “Designing Novel Photocatalysts for Disinfection of MultidrugResistant Waterborne Bacteria” reveals the detail of photocatalysis, a subsidiary
of advanced oxidation processes for water decontamination. The already existing
photocatalysts like titanium dioxide and zinc oxide are being depleted to their core.
So, newer and novel photocatalysts need to be developed with a more proficient,
eco-friendly, and bio-compatible approach. The detail in the chapter aims to have a
closer look at the existing disinfection techniques and the emerging players in the
field of photocatalysis.
Chapter “Magnetic Nanoparticles: Green and Environment Friendly Catalyst for
Organic Transformations” highlights the detail of magnetic nanoparticles or magnetic core–shell nanoparticles that have gained a significant place due to their
paramagnetic nature facilitates the separation of catalyst through the use of an
external magnet which makes the recovery of catalyst easier and prevents loss of
catalyst associated with conventional filtration or centrifugation methods.
Additionally, the possibility of reusability and milder reaction conditions further
enhance the potential of nanoparticle catalyzed organic transformations.
Chapter “A Comprehensive Characterization of Stress Relaxed ZnO Thin Film
at Wafer Level” explores the impact of sputtering parameters on structural, optical,
and mechanical properties of reactive magnetron sputtered ZnO thin film. Stress
relaxed and room temperature deposited ZnO film is highly desirable from fabrication aspects. Theoretical model has been proposed to understand the consequences of oxygen-induced stress in ZnO thin films. It is established that nearly
stress-free, single-phase, and highly c-axis oriented ZnO thin film can be deposited
using a unique combination of sputter parameters.
Chapter “Microstructurally Engineered Ceramics for Environmental Applications”
focusses on use of microstructurally engineered ceramics for environmental applications, e.g., in the development of materials that can be used for treatment of industrial
wastewater. It is well known that industrial wastewater contains toxic ions and dyes.
When such contents cross the permissible limit, it may become an issue of major
environmental concern. The presented work demonstrates the use of microstructurally
designed, phase pure Mg(OH) 2 nanoplatelets 99.99% adsorption of the toxic Cu (II) ion.
