In this research, waste lime sludge (LS) nanoparticles procured from integrated pulp and paper mill were used as the flocculent material to harvest the marine microalgae Tetraselmis indica (T. indica). LS contains 80–85% of calcium carbonate in the form of calcite with rhombohedral and scalenohedral structures along with other minerals such as Mg, K, Fe, and Na. XRD results showed that lime sludge particles have an averaged crystallite size of ~ 39 nm. The biomass harvesting efficiency of T. indica was observed at different doses of flocculent (0–160 mg L−1), temperature (30, 35, 40, 45, and 50 °C) and mixing rate (100–300 rpm), respectively. Maximum biomass harvesting of 86% was observed at 50 °C with 140 mg L−1 flocculent dose, pH 7, and 150 rpm in 90 min. It was also observed that LS has no effect on biodiesel profile of T. indica. Scanning electron microscopy (SEM) images revealed agglomeration of microalgal cells and deposition of calcium carbonate on its surface upon treatment with LS at 50 ºC. Experimental data were found to be in good agreement with pseudo-second-order kinetics model. This study indicated that waste lime sludge is a potential material for high harvesting efficiency in low settling time and low-cost harvesting of microalgae and it makes the production of biodiesel cost-effective. © 2021, The Author(s), under exclusive licence to Springer Nature Switzerland AG.

Stable and dendrite-free Zn anode with artificial desolvation interface layer toward high-performance Zn-ion capacitor

Aqueous Zn-based energy storage devices possess tremendous advantages, such as low cost, high safety,and competitive energy density, due to employing a Zn metal anode and aqueous electrolyte. However,the cycling stability and rate ability of a Zn anode are hindered by Zn dendrite growth and sluggish ion transfer in the electrode/electrolyte interface. Herein, the interfacial properties of Zn anodes are improved through the introduction of a silver(Ag) protective layer, which facilitates uniform Zn deposition and regulates Zn ion transport. As a result, Ag-coated Zn anodes display stable cycling performance(600 h at 1 m A cm^(-2)) and low overpotential(150 mV at 50 mA cm^(-2)after 2000 cycles). The Ag layer in situ electrochemically converts into an AgZn_(3) layer and promotes Zn ion desolvation and threedimensional diffusion processes. Moreover, a Zn-ion capacitor assembled with an Ag-coated Zn anode and active carbon cathode shows a capable cycling lifespan and rate performance. This study provides a feasible strategy for constructing a stabilized and dendrite-free Zn anode for the development of high-performance Zn-based energy storage devices.

The utilization of biowastes for producing biochar to remove potentially toxic elements from water represents an important pathway for aquatic ecosystem decontamination. Here we explored the significance of thiol-functionalization on sugarcane bagasse biochar (Th/SCB–BC) and rice husk biochar (Th/RH–BC) to enhance arsenite (As(III)) removal capacity from water and compared their efficiency with both pristine biochars (SCB–BC and RH–BC). The maximum As(III) sorption was found on Th/SCB–BC and Th/RH–BC (2.88 and 2.51 mg g−1, respectively) compared to the SCB–BC and RH–BC (1.51 and 1.40 mg g−1). Relatively, a greater percentage of As(III) removal was obtained with Th/SCB–BC and Th/RH–BC (92% and 83%, respectively) at a pH 7 compared to pristine SCB–BC and RH–BC (65% and 55%) at 6 mg L−1 initial As(III) concentration, 2 h contact time and 1 g L−1 sorbent dose. Langmuir (R2 = 0.99) isotherm and pseudo-second-order kinetic (R2 = 0.99) models provided the best fits to As(III) sorption data. Desorption experiments indicated that the regeneration ability of biochars decreased and it was in the order of Th/SCB–BC (88%) > Th/RH–BC (82%) > SCB–BC (77%) > RH–BC (69%) up to three sorption–desorption cycles. Fourier-transform infrared spectroscopy and X-ray photoelectron spectroscopy results demonstrated that the thiol (-S–H) functional groups were successfully grafted on the surface of two biochars and as such contributed to enhance As(III) removal from water. Spectroscopic data indicated that the surface functional moieties, such as -S–H, − OH, − COOH, and C = O were involved to increase As(III) sorption on thiol-functionalized biochars. This study highlights that thiol-grafting on both biochars, notably on SCB–BC, enhanced their ability to remove As(III) from water, which can be used as an effective technique for the treatment of As from drinking water.

Computational Insights into Deep Eutectic Solvent Design: Modeling Interactions and Thermodynamic Feasibility Using Choline Chloride & Glycerol

To address climate change and environmental concerns, the chemical process industries are increasingly adopting green technology and exploring eco-friendly waste management practices. Deep Eutectic Solvents (DES) have emerged as promising green solvents with diverse applications in the industries in separation processes, catalysis, drug design, and a lot more. However, the ideal way for modeling ionic interactions within the hydrogen-bond acceptor (HBA) during DES synthesis remains uncertain, and theoretical insight on the formation mechanism of energetically stable DESs from choline chloride (CHL) and urea (URE) is yet to be explored. In this study, we investigate different modeling approaches (no bond, generic bond, or single bond) for ionic interactions in hydrogen-bond acceptor (HBA) molecules during DES synthesis and the thermodynamic feasibility of forming an energetically stable DES using choline chloride (CHL) and urea (URE) through theoretical calculations (PM3, HF, and DFT). Our findings indicate that the choice of modeling approach does not significantly affect the outcomes across calculation levels. The H-X DES formation pathway emerges as the most viable route for CHL: GLC DES synthesis, offering strong binding energy and high exothermicity. This pathway provides a robust solution for synthesizing energetically stable DES with potential applications in various industries. Researchers can consider alternative calculation levels when DFT becomes cost-prohibitive to optimize computational costs. Our study contributes valuable insights into DES design and synthesis, promoting environmentally sustainable and cost-effective processes. © 2023, The Authors. All rights reserved.
