    Biotene: Earth-Abundant 2D Material as Sustainable Anode for Li/Na-Ion Battery
    (American Chemical Society, 2024) Pramanik A.; Mahapatra P.L.; Tromer R.; Xu J.; Costin G.; Li C.; Saju S.; Alhashim S.; Pandey K.; Srivastava A.; Vajtai R.; Galvao D.S.; Tiwary C.S.; Ajayan P.M.
    Natural ores are abundant, cost-effective, and environmentally friendly. Ultrathin (2D) layers of a naturally abundant van der Waals mineral, Biotite, have been prepared in bulk via exfoliation. We report here that this 2D Biotene material has shown extraordinary Li-Na-ion battery anode properties with ultralong cycling stability. Biotene shows 302 and 141 mAh g-1 first cycle-specific charge capacity for Li- and Na-ion battery applications with ?90% initial Coulombic efficiency. The electrode exhibits significantly extended cycling stability with ?75% capacity retention after 4000 cycles even at higher current densities (500-2000 mA g-1). Further, density functional theory studies show the possible Li intercalation mechanism between the 2D Biotene layers. Our work brings new directions toward designing the next generation of metal-ion battery anodes. � 2024 American Chemical Society.

    Unlocking the Secrets of Rhizosphere Microbes: A New Dimension for Agriculture
    (Springer Science and Business Media B.V., 2024) Thakur M.; Khushboo; Shah S.; Kumari P.; Kumar M.; Vibhuti R.K.; Pramanik A.; Yadav V.; Raina M.; Negi N.P.; Gautam V.; Rustagi A.; Verma S.K.; Kumar D.
    Rhizospheric microbes help plants to acquire and assimilate nutrients, improve soil texture and modulate extracellular molecules. Rhizosphere bacteria regularly encounter a copious number of variables, such as temperature, pH, nutrients, pest resistance mechanisms, etc. The extracellular concentration of chemical messengers fabricated by plant growth promoting bacteria (PGPB) in a system is directly proportional to the bacterial population. To dwindle the use of chemically synthesised pesticides, plant growth-promoting rhizobacteria (PGPR) are new arsenals of imperishable agricultural practises for managing plant pathogens and resistance. This review aims to harness the rhizosphere milieu to raise climate smart crops. The PGPB mediated hormonal control of plant stress management pathway could be potentially modified for the benefit of plants. Nutrient solubilisation strengthens the rhizomicrobiome for phytoremediation and pathogen control. Quorum sensing as well as the role of enzymes and siderophores in rhizo-microbiome has been discussed. With advent of metagenomics, the understanding of soil microbiome ecology has acquired new dimensions and has enabled us to modify the microbiome for sustainable agriculture and enhanced productivity. � The Author(s), under exclusive licence to Springer Nature B.V. 2024.
