Sustainable carbonaceous nanomaterial supported palladium as an efficient ligand-free heterogeneouscatalyst for Suzuki-Miyaura coupling
A novel ligand-free heterogeneous catalyst was synthesized via pyrolysis of Samanea saman pods to produce carbon nanospheres (SS-CNSs), which served as a carbon support for immobilizing palladium nanoparticles through an in situ reduction technique (Pd/SS-CNS). The SS-CNSs effectively integrated 3% of Pd on their surfaces with no additional activation procedures needed. The nanomaterials obtained underwent thorough characterization employing various techniques such as FT-IR, XRD, FE-SEM, TEM, EDS, ICP-AES, and BET. Subsequently, the efficiency of this Pd/SS-CNS catalyst was assessed for the synthesis of biaryl derivatives via Suzuki coupling, wherein different boronic acids were coupled with various aryl halides using an environmentally benign solvent mixture of EtOH/H2O and employing only 0.1 mol% of Pd/SS-CNS. The catalytic system was conveniently recovered through centrifugation and demonstrated reusability without any noticeable decline in catalytic activity. This approach offers economic viability, ecological compatibility, scalability, and has the potential to serve as an alternative to homogeneous catalysis. 2024 RSC. -

Sustainable approach to life in water: Science and ethics of the oceans
Oceans have always remained a mystery to humankind. We owe the oceans the very air we breathe. Oceans are storehouses of nutrient rich food that can alleviate the hunger of many generations to come, offer rich minerals and medicines to cure many diseases, regulate the temperature of our planet, stabilize weather patterns, and provide livelihood for many in the fishing and tourism industry. But sadly they are overexploited and polluted to the core. The very fact that these mighty oceans have started showing the ill effects of anthropogenic activities itself is testimony to the tremendous greed of humanity. Among all the mighty oceans, the Arctic ocean is the most sensitive and vulnerable to these changes as it holds a pivotal position in maintaining life on Earth by different mechanisms. The Sustainable Development Goal (SDG) 14 of the United Nations underlines the urgent need to conserve marine resources and give equal rights to people in all countries to enjoy these resources. The current review is an attempt to highlight the enormous number of ways in which oceans have helped humankind, the serious threats the oceans are facing now, and how best we can have a sustainable approach to halt the total crashing of our great ocean systems. 2021 Journal of Dharma: Dharmaram Journal of Religions and Philosophies (DVK, Bangalore). -

Surviving Under Stress: Exploring Zea mays Adaptive Responses to Cadmium Toxicity and Mitigation StrategiesA Review
Cadmium (Cd) toxicity poses a significant threat to Zea mays, disrupting its normal physiological functions and metabolic processes. This chapter summarises current studies on the sources of contamination, Cd intake mechanisms, and the effect of Cd toxicity on critical physiological systems in maize. It then thoroughly investigates Zea mays physiological and adaptive responses to Cd toxicity. The section outlines how Cd inhibits vital metabolic processes, such as photosynthesis and the absorption of nutrients uptake in maize plants, leading to a reduction in biomass, yield, and growth. The adverse impacts on plant growth and development are amplified by anatomical changes brought on by Cd exposure, such as modifications to the roots and leaves. Furthermore, a thorough examination of biochemical modifications is conducted, such as adjustments to protein composition, glucose metabolism, and amino acid levels. The chapter additionally examines how enzymatic activity responds to Cd stress, focusing on modifications in the activity of enzymes involved in antioxidants and metabolism. Under the influence of Cd toxicity, maize plants display a range of intricate adaptive responses. These include upregulation of genes linked to the production of ethylene and the synthesis of peptides that bind metals, such as phytochelatins. The study covers the effectiveness of several mitigation techniques employed to reduce Cd accumulation and improve Cd tolerance in maize crops. These techniques include microbial remediation, phytohormone administration, biostimulant treatments, and designed nanoparticles and mineral ions. With everything considered, this chapter offers insightful information about Zea mays physiological and adaptive responses to endure and mitigate the impact of cadmium toxicity. To ensure sustainable maize production and food security in areas polluted by Cd, it is essential to understand these mechanisms and create appropriate mitigation techniques.
