A hyperaccumulation pathway to hierarchically porous carbon nanosheets from halophyte biomass for wastewater remediation!
We are delighted to have published this research work in the reputed sustainable and materials technology, Elsevier. We congratulate Dr. Ashesh Mahto on his efforts in this work wherein a single step process to obtain porous carbon nanosheets (CNS) by exploiting the hyperaccumulating pathway in extreme halophyte, Salicornia brachiata to achieve the sustainable and eco-friendly production. The process was designed so as to achieve seamless hybridization with already existing technologies of salt production while reducing the overall carbon and chemical footprint. Further, CNS were tested as an efficient adsorbent for wastewater remediation.
Also, hearty congratulations to all the co-authors, Ankit Singh, Kanakaraj Aruchamy, Ashok Maraddi, and Gopala Ram Bhadu. Congratulations to the corresponding authors Prof. Nataraj Sk and Dr. Ramavatar Meena without whose support it would be impossible.

This work revolves around usage of orthorhombic crystal structure of the V3O7·H2O material with large interlayer spacing with open tunnels capable of showing intercalation mechanism. Meanwhile, its structural degradation and dissolution leading to the quick capacity fading are studied in detail. These issues were addressed by modifying the V3O7·H2O material by pre-intercalating with Ag(I) inside the layers and simultaneous in situ composite formation with reduced graphene oxide (rGO).

Herein, a new protein engineering strategy with improved efficacy is demonstrated through judicious task-specific functionalization of Cyt C with quantum dots (QDs) and ionic liquids (ILs). Mn2+ doped ZnS QD and ILs ([Cho][Ac]; [Cho][Dhp]) were concomitantly used to decorate Cyt C, which was characterized using various analytical tools. The peroxidase activity at room temperature of engineered Cyt C (Cyt C-QD-IL) increased markedly (1.2 to 3.5-fold) as compared to that for bare Cyt C, Cyt C with QD, and Cyt C with ILs. Further, Cyt C-QD-IL showed better catalytic activity under various stresses such as high temperature (110 °C), presence of a chemical denaturant (6 M GuHCl), high oxidative stress (30 min H2O2), and presence of proteases.
