Rohan, Neil S. Curtis, Abhishek Lahiri, Yinghe He, S. Lanceros-Mendez Progress in Materials Science, 2025 Battery systems are essential components of the on-going energy transition and digitalization of society. With the need to power an increasing variety of portable and stationary systems, ranging from disposable point-of-care devices or smart packaging systems to applications in portable computers and electric cars, an increasing variety of batteries and battery systems are being developed, each aiming to specific sets of required performance parameters, including energy and power density, cycling stability, flexibility, degradability, environmental impact or improved integration into the specific application context. This work analyzed the state of the art of the different materials and geometries, performance parameters and applications of the different battery systems. We discuss the rationale behind each material selection, the processing technologies and the integration into the specific application, taking into account the whole life-cycle of the battery. Further, the main challenges posed for each battery type will provide a roadmap for their successful development and application.
Nanofiltration in wastewater treatment Roopa Rani, Harsha Devnani, A. Jayamani, Arpit Sand Nanotechnology for Wastewater Treatment, 2025 As pure water is considered to be the best medicine in the world, there are serious concerns about water scarcity and water pollution all over the world to find a sustainable way to treat and reuse water. Although traditional wastewater treatment methods are effective, they face problems in terms of adaptability, making them unsuitable and preventing further development. The use of membrane technology in wastewater treatment has received great attention with proven results for removing pollutants, color, and COD/BOD, as well as the reclamation of cleaning solutions. The nanofiltration technique is ahead of all other membrane technologies of wastewater treatment and has more scope for advancements. This book chapter emphasizes the nanofiltration process with more insight into nanofiltration membranes, basic principles involved, mechanism, mathematical modeling of the membrane, use of polymers, and reasons for fouling of membranes used in nanofiltration. The chapter extends its discussion with inputs on the current scenario in the implementation of this technique for surface water, groundwater, fouling control, and effective water reuse. The summary of this book chapter provides information on future aspects of the nanofiltration process, which is expected to address current and future water treatment challenges, paving the way for cleaner and safer water resources worldwide.
Nanotechnology and Bionanotechnology: An Overview Jaya Tuteja, Roopa Rani, Chetna Sharma, Harsha Devnani Bionanotechnology for Advanced Applications, 2024 The term “nano” always raises a question about whether is it small or huge. “Nano” implies one billionth (10–9), such as of a meter, which is small, but if we focus on the application of nanotechnology it is huge. Nanotechnology is that division of technology which deals with materials having at least one or more dimensions ranging from 1 to 100 nm. This vast nanomaterial range opens the gateway for scientists to utilize the distinct optical, chemical, physical, and mechanical properties of materials which show significant enhancements in their inherent properties on account of dominating quantum effects. Nanotechnology is a perfect combination of science and engineering which comprises of basic knowledge and concept of physics, chemistry, and biology, along with advancements in designing and manufacturing on the basis of engineering and technology. Nanotechnology has seen an emerging trend in biological applications, specifically in combination with biotechnology principles. Biotechnology in alliance with nanotechnology principles is paving the foundation for a new field of “bionanotechnology,” with vast applications in the areas of medicine, industry, agriculture, and the environment. This chapter provides an overview of the emerging nanotechnology and related dimensions in terms of its applications, current challenges, and future perspective.
Supersensitive Detection of Anions in Pure Organic and Aqueous Media by Amino Acid Conjugated Ellman's Reagent Sameer Dhawan, Harsha Devnani, Jisha Babu, Hanuman Singh, M. Ali Haider, Tuhin S. Khan, Pravin P. Ingole, V. Haridas ACS Applied Bio Materials, 2021 The last few decades witnessed a remarkable advancement in the field of molecular anion receptors. A variety of anion binding motifs have been discovered, and large number of designer molecular anion receptors with high selectivity are being reported. However, anion detection in an aqueous medium is still a formidable challenge as evident from only a miniscule of synthetic systems available in the literature. We, herein, report 5,5'-dithio-bis(2-nitrobenzoic acid) (Ellman's reagent) appended with amino acids as supersensitive anion sensors that can detect F- and H2PO4- ions in both aqueous as well as organic media. Interestingly, the sensors showed a dual response to anions, viz., chromogenic response in organic medium and electrochemical response in aqueous solutions. Various spectroscopic techniques such as UV-vis and 1H NMR are used to investigate the binding studies in acetonitrile, whereas electrochemical methods such as cyclic voltammetry (CV) and differential pulse voltammetry (DPV) are employed to explore the anion binding in water. The host-guest complex stoichiometry and binding constants are calculated using the BindFit software. The geometry of host-guest complex has been optimized by the density functional theory (DFT) method. These molecules are versatile sensors since these function in both water and acetonitrile with extremely low limit of detection (LOD) up to 0.07 fM and limit of quantification (LOQ) up to 0.23 fM. To our knowledge, the present system is the first example of a sensor that can detect the lowest concentration of anions in water quantitatively. The minimalistic design strategy presented here opens up the innumerable possibilities for designing dual anion sensors in a one fell swoop.
Copper/Cuprous Oxide Nanoparticles Decorated Reduced Graphene Oxide Sheets Based Platform for Bio-Electrochemical Sensing of Dopamine Harsha Devnani, Nusrat Rashid, Pravin P. Ingole Chemistryselect, 2019 A rudimentary simple sonochemical approach has been employed for the synthesis of copper/cuprous oxide nanoparticles (Cu/Cu2O NPs) decorated graphene oxide (GO) sheets. Simply, an aqueous dispersion of GO was sonochemically treated with Cu/Cu2O NPs as obtained through a simple electrochemical dissolution method to get the Cu/Cu2O/rGO nanocomposite. The decoration of Cu/Cu2O NPs on GO sheets resulted in the excellent sensing activity of Cu/Cu2O/rGO nanocomposite towards dopamine in the pharmaceutical formulation at the electrode interface due to enhanced electron mobility in GO sheet and high catalytic activity of Cu/Cu2O NPs. The comparison has been laid out based on various characterization techniques viz. powder X‐ray diffraction (PXRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), Fourier transform infra‐red (FTIR) spectroscopy and Raman spectroscopy. The fabricated sensor depicted high sensitivity of 0.806 μA/μM for dopamine in a broad linear range of 0.25 –17 μM. Moreover, the remarkable detection limit of 2.6 nM was found for dopamine, and the developed sensor exhibited a wide separation ca. 140 mV between the respective detection peaks of dopamine and uric acid, which is a major interferent in the analysis of dopamine.
