Sesbania bispinosa (Jacq.) W. Wight is a weedy green manure plant of the family Fabaceae. The legume plants play a major role in nitrogen fixation and soil fertility while biochar plays a significant role in environmental remediation. The present study has aimed to convert S. bispinosa in combination with cow dung (1:1, v/v) into enriched vermicompost through the amendment of different concentrations of activated Prosopis wood biochar. Totally 10 treatments were maintained: VSB1-VSB5 and SB1-SB5 with and without earthworms, respectively. The treatments were maintained under controlled environmental conditions in triplicate till 28 days. The initial and final samples of the treatments with and without earthworms were analyzed for physicochemical characteristics, FTIR analysis and phytotoxicity assay. The pH, total organic carbon, C/N ratio and C/P ratio showed a declining trend while the nutrients, total nitrogen, phosphorus, potassium, calcium and sodium contents displayed increment towards the progression of vermicomposting. A total nitrogen content of 2.78% was recorded in vermicompost amended with 3% biochar followed by 2.61% in 2% biochar amendment. The functional group changes from initial substrates to final vermicompost inferred through FTIR analysis denote the decomposition of complex organic materials into simple forms. The lowest C/N ratio (19.06) with a higher germination index (102.85%) of Vigna mungo (black gram) seeds were observed in the vermicompost of S. bispinosa + cow dung substrates amended with 3% biochar within a very short period of time (28 days). Hence, the use of biochar at a 3% level is recommended for the vermiconversion of green manure biomass to obtain nutrient-amplified vermicompost. It is also beneficial to use 2% biochar in vermicomposting, however, 3% biochar amendment is highly beneficial and a better choice from a vermicompost quality perspective.

Capacitive deionization (CDI) represents a novel technology for the desalination and purification of seawater. Selecting the appropriate electrode material is crucial, with carbon electrodes frequently employed owing to their high specific surface area, extensive porous structure, and environmentally sustainable nature. This study presents a nitrogen-doped porous carbon, derived from household waste, which demonstrates outstanding electrochemical and desalination performance. The purified chitosan was mixed with a specific ratio of CaCO3 and carbonized at 800 °C to produce chitosan porous carbon (CPC-T). To verify the role of the templating agent, its performance was compared with chitosan porous carbon (CPC) prepared by direct carbonization. CPC-T possesses more mesoporous structures (31.25%), shortening ion transport pathways and significantly enhancing charge transfer rates. The nitrogen-rich doping (8.65 at%) provides numerous active sites and excellent conductivity, making it highly appropriate for capacitive deionization applications. Compared to CPC prepared without a templating agent, CPC-T has a higher specific capacitance (101.5 F g−1 at a scan rate of 2 mV s−1) and good cycling stability. The CDI cell made from it exhibits a salt adsorption capacity (SAC) of 25.8 mg g−1 for 500 mg L−1 NaCl solution at an applied voltage of 1.4 V, retaining 88% capacity after 50 adsorption–desorption cycles, demonstrating excellent desalination regeneration performance. Additionally, among different concentrations of salt solutions, the CPC-T material shows the best desalination performance for the test solution at a concentration of 500 mg L−1. For different solute ions, the CDI cell with this material as the electrode exhibits excellent desalination performance for Ca2+, with a SAC value of up to 34.02 mg g−1. This is a self-doped porous carbon material that significantly outperforms traditional carbon-based materials.

Wearable thermoelectric devices offer a transformative approach to energy harvesting, providing sustainable solutions for powering next-generation technologies. In pursuit of efficient, flexible, biocompatible, and cost-effective thermoelectric materials, zinc oxide (ZnO) has emerged as a distinctive candidate due to its unique combination of favorable properties. This study explores the growth and optimization of ZnO nanorods on conductive carbon fabric (CF) using a simple microwave-assisted solvothermal technique. This method circumvents traditional complex processes that typically involve high temperatures or lengthy growth times, offering advantages such as rapid, uniform, and controllable volumetric heating. By systematically varying growth parameters, including microwave power and reaction time, we established conditions that promote the vertical alignment of ZnO nanorods, essential for enhancing thermoelectric performance. Structural and morphological analyses highlight the pivotal influence of the seed layer and growth parameters in achieving dense, uniform growth of ZnO nanorods. Interestingly, at higher microwave power levels, a transformation from nanorod structures to sheet-like morphologies was observed, likely due to Ostwald ripening, where larger particles grow at the expense of smaller ones. The optimized growth conditions for achieving superior growth and thermoelectric performance were identified as 15 min of growth at 100 W microwave power. Under these conditions, ZnO nanorods exhibited enhanced crystallinity and a higher growth rate, contributing to an improved thermoelectric power factor of 777 nW/mK2 at 373 K. This work underscores the importance of precise parameter control in tailoring ZnO nanostructures for wearable thermoelectric applications and demonstrates the potential of scalable, low-cost methods to achieve high-performance energy-harvesting materials.
