pH-Independent Selective Formation of VO Motif Incorporating a Family of Hydrazone Ligands: Synthesis, Structure, and Luminescence-Based Sensing Studies toward Selective Metal Ions.

Two new dioxidovanadium(V) compounds with the general formula [VO(L)] (L = hydrazone ligand) were synthesized using three different methods (acidic, neutral, and basic media) with either VOSO. 5HO, [VO(acac)], or NHVO as the starting material and hydrazone ligands. In both cases, five coordinated V ions adopted distorted square pyramidal geometry through the coordination of two oxido ligands and one hydrazone ligand.

Integrated CO capture and electrochemical upgradation: the underpinning mechanism and techno-chemical analysis.

Coupling post-combustion CO capture with electrochemical utilization (CCU) is a quantum leap in renewable energy science since it eliminates the cost and energy involved in the transport and storage of CO. However, the major challenges involved in industrial scale implementation are selecting an appropriate solvent/electrolyte for CO capture, modeling an appropriate infrastructure by coupling an electrolyser with a CO point source and a separator to isolate CO reduction reaction (CORR) products, and finally selection of an appropriate electrocatalyst. In this review, we highlight the major difficulties with detailed mechanistic interpretation in each step, to find out the underpinning mechanism involved in the integration of electrochemical CCU to achieve higher-value products.

'On and Off' intercalative binding behaviour of double chain surfactant cobalt(III) complex containing 2, 2'-bipyridyl ligand in β-Cyclodextrin: A detail approach on Host-guest inclusion of surfactant cobalt(III) complex and CT-DNA binding in micro-heterogeneous medium.

The binding interaction of surfactant cobalt(III) complex, cis-[Co(bpy)(HA)](ClO), in which bpy is 2,2-bipyridine and HA is hexadecylamine or cetylamnine with DNA was through intercalative mode via the long aliphatic chains present in the ligands.

Synergistic optimization of electrocoagulation process parameters using response surface methodology for treatment of hazardous waste landfill leachate.

Leachate treatment is an essential and integral part of solid waste management system, and its efficient treatment becomes more crucial when the leachate is produced from industrial or hazardous waste landfills (HWLs), as it is multi-fold more toxic than the leachate produced from municipal solid waste landfills (MSWLs). Electrocoagulation has appeared to be a promising technology for treating complex wastewater including MSWL leachate, but specific treatability studies dedicated to HWL leachate are rarely available, and thus pose a demand for fundamental and advance research in this area to bridge the existing gap. The current study delves into systematic design of experiments to check the treatability of HWL leachate through electrocoagulation, considering reduction (maximum) in chemical oxygen demand (COD) as a response variable.

Reduction of chemical oxygen demand through electrocoagulation: an exclusive study for hazardous waste landfill leachate.

Leachate produced from hazardous waste landfills has been observed to exhibit very complex characteristics including the presence of a high amount of refractory organics and toxic elements which make it unfit for conventional treatment. This study is focused on the characterization and treatability of "hazardous waste landfill leachate" through electrocoagulation for the reduction of chemical oxygen demand (COD). Effect of different operating parameters, such as electrode material, interelectrode distance (IED), current density (CD), and electrolysis time (ET), has also been studied.

SARS-CoV-2 and other pathogens in municipal wastewater, landfill leachate, and solid waste: A review about virus surveillance, infectivity, and inactivation.
