    Abstract: This contributed volume comprises of detailed chapters covering the biotechnological approaches employed for the removal of toxic recalcitrant xenobiotics such as petroleum hydrocarbons, textile dyes, microplastics and synthetic polymers that pose serious threat to the environment. It also includes the waste to energy conversion strategies that provides a deep insight on the need for waste circular economy for different developing countries and its implication on sustainable development goals such as SDG 12 (responsible consumption and production) SDG 14 (Life below water); and SDG 15 (Life on land). Emerging pollutants sourced from both industries and anthropogenic activity have created havoc in recent years for public health and destruction of biodiversity at multiple levels. The alarming increase in the global population and rapid industrialization might aggravate the problems associated with these hazardous pollutants in near future. Effluent from different industries may contain high amounts of xenobiotic hazardous contaminants such as dyes, hydrocarbons, synthetic surfactants, microplastics, etc. Industries and public sewers handling such waste streams are facing a plethora of challenges in the effluent treatment and solid waste disposal due to various factors that start from production to adoption of appropriate technologies. Therefore, there is an immediate circumvention of bottlenecks through sustainable mitigation strategies. This book is of interest to teachers, researchers, climate change scientists, capacity builders and policymakers. Also, the book serves as additional reading material for undergraduate and graduate students of agriculture, forestry, ecology, soil science, and environmental sciences. National and international agricultural scientists, policy makers also find this to be a useful read.

    Description: The first expedition on board research vessel Sagar Nidhi conducted as a part of the International Indian Ocean Expedition­ 2 explored the western Arabian Sea concluded its mission gathering useful data for oceanographic studies. The 18 ­day expedition, led by PN Vinyachandran of the Indian Institute of Science, Bangalore and Satya Prakash of Esso-Indian National Centre for Ocean Information Services, Hyderabad, was flagged off in Goa on December 4, and concluded at Mauritius on December 22. The data collected will help elucidate the currents and water masses in the western Indian Ocean in detail and facilitate in understanding of the oceanography.

    Notes: A multi-ion-beam reactive sputter (MIBERS) deposition technique was devised to grow ferroelectric lead zirconate titanate (PZT) thin films of different compositions (Zr/Ti ratios of 50/50 and 56/44) from individual metal targets of Pb, Zr, and Ti. This technique offers a highly controllable deposition process allowing excellent uniformity in composition and thickness over a large area (7.5 cm diameter) on a reproducible basis. The PZT films were deposited on a variety of unheated substrates and annealed by two different techniques, rapid thermal annealing and conventional furnace annealing. Both techniques induced a perovskite phase with good morphology. The effect of the excess Pb content was observed in terms of the crystallization and morphology. It was seen that the presence of excess Pb tends to enhance perovskite phase formation but degrades the morphology. The effect of the substrates was observed in terms of crystallization and orientation. A low-energy oxygen ion beam was employed to modify the film growth. Secondary-ion bombardment seems to be a promising approach to optimize the film quality as it showed a variety of effects such as enhancing crystallization, inducing preferred orientation, and improving the film morphology. The present MIBERS-grown PZT films showed fairly high dielectric constants, about 850 for PZT (50/50) and about 1150 for PZT (56/44), and low dielectric losses. Ferroelectricity of these films was established with the values of the remnant polarization and the coercive field for PZT (50/50) of 23 μC/cm2 and 80 kV/cm and for PZT (56/44) of 20 μC/cm2 and 60 kV/cm, respectively. The low-energy oxygen ion-beam bombardment during the growth of PZT (50/50) films caused an increase in the dielectric constant to about 1000, reduction in the dissipation factor to 0.02, increase in the remnant polarization to about 26 μC/cm2, and decrease in the coercive field to about 60 kV/cm. The C-V characteristics of PZT (50/50) films in a metal-ferroelectric-metal configuration also indicated a clear dielectric polarization hysteresis.

    Notes: The relation between gold related levels in silicon is studied with deep level transient spectroscopy (DLTS) using linearly graded junctions. Since the depletion layer extends equally on both sides in the linearly graded junction, both the acceptor level in the upper half and the donor level in the lower half of the band gap are simultaneously monitored as majority-carrier traps. It is observed that the concentration of the acceptor level is about four times more than the donor level. The defect concentrations have been calculated using modified DLTS theory for linearly graded junctions where the influence of free-carrier tail has been properly considered for both the traps. The difference in concentrations indicates that the two deep levels originate from different configurations of the gold impurity in silicon.

    Notes: Trapping characteristics of two peaks, named A and B, associated with the well-known DX center in molecular-beam epitaxial grown, silicon-doped AlxGa1−xAs (x=0.36) are studied by deep-level transient spectroscopy as function of filling pulse width. With increase in filling pulse duration, several interesting features are noted including interdependence of the two peaks apparently logarithmic increase in height, shift in the peak temperature of the low-temperature peak B, and sharp reduction in its width. These unusual features provide clues to the dynamics of carrier capture and emission at the defect. We propose a model to qualitatively explain these features.

    Notes: The phenomenon of two-stage photoquenching of EL2 defect in semi-insulating GaAs [V. Pandian and V. Kumar, J. Appl. Phys. 70, 5114 (1991)] is further investigated by sequentially irradiating the sample with different energy photons in the quenching band at constant temperature. The results of the new experiments, which are similar to the sequential quenching experiments with fixed photon energy at different temperatures, support the conclusion that the two-stage quenching may be related to the possible lattice strain mediated cooperative structural distortion arising out of transition of EL2 to the metastable state.
