The development of biocompatible and biodegradable information storage devices represents a significant step toward next-generation, eco-friendly electronics. Bio-based resistive-switching memory devices have been successfully fabricated using the gum of Azadirachta indica and Anacardium occidentale, as well as the latex of Artocarpus heterophyllus, Artocarpus altilis, and Calotropis gigantea. The fabricated biomemristor devices, comprising Ag/gum or latex/ITO architecture, exhibited good resistive-switching memory behavior. Remarkably, the gum-based samples demonstrated a moderately high ON/OFF current ratio of 102, whereas the latex-based samples outperformed them with a substantially higher ratio of 103. This study demonstrates the potential for utilizing gum and latex, often regarded as non-essential byproducts, to fabricate functional devices. The switching mechanism for the memory characteristics can be attributed to the formation of conductive filaments caused by the migration of oxygen vacancies and metal ions through the bioactive layer. Additionally, the resulting devices can degrade naturally without harming the surrounding environment. Therefore, this work is a promising platform for the sustainable development of environmentally friendly or green electronic technologies.

This study introduces an integrated method to assess flood inundation and agricultural impact in the flood-prone Ghatal Subdivision, West Bengal, India, from 2016 to 2024. Combining Sentinel-1 (S1) SAR GRD imagery, advanced U-Net deep learning for precise flood mapping, Light Gradient Boosting Machine for flood depth estimation, and farm household survey, the research quantifies flood dynamics and crop losses. Results show that 30–40

Graphite oxide (GO) is a promising material with unique physicochemical properties with a highly attractive feature for a wide range of technological applications. The properties of GO can be tailored by functionalizing the material with interesting electroactive moieties. This work investigates the chemical functionalisation of GO using a catalytically well-known organometallic moiety, i.e., N-heterocyclic carbene (NHC) copper complex, and its successful characterisation through spectroscopic techniques. Comprehensive characterisation using FT-IR, Raman spectroscopy, TGA, and SEM–EDX confirmed successful covalent functionalisation, along with increased lattice disorder, enhanced thermal stability, and uniform Cu distribution across the wrinkled GO sheets. Electrochemical studies using CV, EIS, GCD, and capacitance retention have revealed that the organometallic-functionalized GO could be a potential candidate for a supercapacitor application. Electrochemical studies demonstrated that the Cu-NHC functionalised GO exhibits significantly reduced charge transfer resistance ( 4.8 Ω), fast ionic diffusion, and stable redox reversibility. The hybrid electrode delivered a specific capacitance of 172 F/g with 86

A class of benzohydrazide-linked 4,6-O-protected N-glucosylamine derivatives was synthesized under ambient conditions with good yields and characterized by Nuclear Magnetic Resonance, High Resolution Mass Spectroscopy, and Density Functional Theory calculations. Anomeric forms of the N-glucosylamines were assigned from 1H NMR spectroscopy. These derivatives showed good gelation behaviour in aromatic solvents upto 1.0
