By operating at relatively low temperatures, LPCS minimizes oxidation and residual stress, enabling the deposition of heat-sensitive and high-reflectivity materials. Despite these benefits, LPCS faces critical challenges, particularly in achieving high deposition efficiency, ensuring compatibility with brittle and soft substrates, and maintaining operational stability in diverse environments. This study provides a comprehensive review of the key parameters influencing LPCS performance, including gas pressure, gas temperature, nozzle geometry, stand-off distance, and powder feeding systems.

This research endeavors to explore the function of nuclear energy as a viable, low-carbon substitute within the framework of India's energy transition. Notwithstanding its elevated capacity factor (&gt;85 %), nuclear energy presently accounts for a mere 3 % of the nation's electricity generation as of 2024. The investigation presents a thorough evaluation of India’s nuclear infrastructure, which comprises 22 operational reactors (6780 MW) and strategic initiatives aimed at augmenting capacity to 22,480 MW by 2031. The study accentuates pivotal technological innovations such as Fast Breeder Reactors (FBRs), small modular reactors (SMRs), and the utilization of India’s vast thorium reserves (846,000 tonnes) as integral components of the three-stage nuclear program. It further analyzes obstacles, including constraints on the supply of uranium, rigorous regulatory frameworks, and societal opposition. Through an international comparative analysis and policy assessment, this research delineates pathways for the enhancement of nuclear development, encompassing regulatory reforms, public engagement strategies, increased investment in research and development (R&amp;D), participation from the private sector, and fostering global collaboration. The results emphasize the essential role of nuclear energy in fulfilling India's net-zero emissions objective by 2070 while simultaneously bolstering energy security and fostering technological self-sufficiency.

This review proposes a novel integrated approach using green chemicals and energy-efficient methods to optimize resource use and minimize waste, aligning with circular bioeconomy principles based on findings from existing studies. Existing studies have demonstrated that the use of DES for microalgae pretreatment in bio-compound extraction was influenced by water content and polarity which affected extraction yields of up to 80%. Critically, despite existing studies highlighted the versatility of DES to extract both polar and non-polar bio-compounds individually or sequentially through effective selectivity with high extraction efficiencies of up to 90%, limited study has been directed towards an integrated approach of bioprocessing pathway. Furthermore, although cell disruption and extraction have been identified as critical steps in lifecycle of microalgae biorefinery, existing studies have predominantly treated them as separate processes. Hence, future studies should investigate the potential to integrate cell disruption and extraction in a single process using tailored DES-ABS for selective extraction of multiple bio-compound from microalgae. Potential for synergistic effects particularly with ultrasound assistance should be explored to reduce costs, enhance yields and enable scalability.
