Here, we report a facile green chemistry route to synthesize zinc oxide (ZnO) nanoflakes using the leaf extract of C guianensis Aubl. (CGLE) as a potential bioreductant. Heterocyclic active constituents present in CGLE predominantly influences the reduction and forms a complexation with ZnO nanomaterials. XRD analysis confirms the growth of hexagonal ZnO with the corresponding planes at 31.8 degrees (100), 34.5 degrees (002), 36.3 degrees (101), 47.6 degrees (102), 56.6 degrees (110), 62.9 degrees (103), 66.4 degrees (002), 67.9 degrees (112), 69.0 degrees (201), and 76.9 degrees (202). Further, it was also demonstrated that the fabricated ZnO was highly stable possessing negative zeta value (-20.7 mV) and UV-Visible spectroscopy has shown the absorbance maxima at 367 nm. Interestingly, synthesized ZnO nanomaterials exhibits an excellent bactericidal effect against human pathogens and displays very less hemoglobin release, which clearly depicts its suitability to use in diverse nanomedicinal applications.

In Situ/Operando Characterization Techniques: The Guiding Tool for the Development of Li-CO2 Battery

Ankit K. Chourasia, Anil D. Pathak, Chandrasekhar Bongu, K. Manikandan, Sai Praneeth, Keerti M. Naik, Chandra S. Sharma

Summary: Li-CO2 batteries have gained significant importance due to their higher gravimetric energy density compared to conventional Li-ion batteries and their ability to utilize CO2 for energy storage. However, challenges such as slow CO2 reduction/evolution, interface blockage, high overpotential, and electrolyte instability hinder their progress. Efforts have been made to develop catalysts, improve electrolyte stability, and protect the anodes. Lack of understanding of the reaction mechanisms slows down the development of Li-CO2 batteries. In situ characterization techniques can help bridge this gap by monitoring the processes during reactions.

Experimental and theoretical insights into colossal supercapacitive performance of graphene quantum dots incorporated Ni3S2/CoS2/MoS2 electrode

Omkar Sangabathula, Manikandan Kandasamy, Brahmananda Chakraborty, Chandra S. Sharma

Summary: Transition metal sulfides (TMS) are promising electrode materials for supercapacitor applications. To overcome the deficiency of individual metal sulfides, the combination of pseudocapacitive transition metals with conductive carbon material can be a plausible solution. In this work, flower-like Ni3S2/CoS2/MoS2 (NCMS) and Ni3S2/CoS2/MoS2-GQDs (NCMS-G) structures were fabricated directly on Ni foam using a hydrothermal synthesis method. The NCMS-G-2.5 electrode showed high specific capacitance, excellent rate capability, and good cycling stability. Furthermore, an assembled NCMS-G-2.5//rGO asymmetric supercapacitor (ASC) device exhibited excellent energy density and superior cycling performance. The interactions between Ni3S2/CoS2/MoS2 and carbon based nanostructure GQDs were investigated using Density Functional Theory (DFT) simulations, revealing enhanced electronic states near Fermi level and improved conductivity for the hybrid structure. The fabricated 3D flower NCMS-G-2.5 has potential prospects for developing advanced and high-performance energy storage devices.
