Summary: Loquat leaves have been proven effective as a biosorbent for removing neodymium(III) and cerium(III) ions from aqueous solutions. The sorption process is accurately described by the pseudo-second-order kinetic equation, while the Langmuir model fits the sorption isotherm well. Desorption studies showed higher percent recovery for neodymium(III) ions compared to cerium(III) ions.

Summary: In this study, the electrosorption process of weak metal cyanide complexes using coal-based electrode was investigated. The results revealed that the adsorption kinetics followed a second-order model and the adsorption isotherms were in accordance with the Langmuir model. The mechanism involved the dipole force and exchange of coordination groups. The electrosorption process led to the formation of zinc oxide precipitates and the electrostatic adsorption of a small amount of copper ions. These findings provide valuable insights into the removal characteristics of weak metal cyanide complex ions and offer significant implications for the treatment of cyanide wastewater using electrosorption technology.

Summary: This study focused on the removal of Drimaren Turquoise CL-B reactive dye using the white rot fungus Schizophyllum commune, considering current environmental conditions. Various parameters such as pH, carbon and nitrogen sources, temperature, dye concentration, and C/N ratio were investigated. The highest dye removal (95.45%) was achieved at pH 4.5, temperature 35°C, inoculum size 3 mL, veratryl alcohol mediator, glucose carbon source, and ammonium nitrate nitrogen source. The enzyme activity assay showed low laccase and lignin peroxidase (LiP) activity, while manganese peroxidase (MnP) activity was the highest. Maximum biosorption occurred at pH 1 and 313 K. The pseudo-2(nd)-order kinetic model and Freundlich isotherm were the best fit for dye removal. Overall, white rot fungus shows promise as an excellent biomaterial for removing synthetic dyes from wastewater.

Summary: The study examines the levels of ambient air pollutants in two major industrial estates before and during the COVID-19 pandemic. Data from certified laboratories of the Environmental Protection Agency (EPA) were collected. The results show that the ambient air pollutants exceeded the Punjab Environment Quality Standards (PEQs) limit before the pandemic, but were within the limits during the lockdown. The decline in emissions from sources like vehicles and industries during COVID-19 and limited human movement contributed to this gradual change.

Summary: Our research focuses on the properties of N-heterocyclic carbene salts and their silver acetate-based complexes, including their structure, biology, and electronics. We synthesized compounds after conducting theoretical calculations, using B3LYP functional with 6-31++G and LanL2DZ basis sets for salts and complexes, respectively. Non-covalent interactions were evaluated, and electronic parameters, HOMO and LUMO energies, were calculated to assess their biological potential. Density of states analysis was conducted to examine electronic densities. Compound 3, with an energy gap of 0.121 eV, was considered the best among all compounds. Due to reasonable HOMO-LUMO energy gaps, all eight compounds were deemed feasible for synthesis and showed strong biological potentials. Characterization of compounds was done using FT-IR and NMR spectroscopy.

Summary: Environmental sustainability requires efficient environmental and economic policies. Advancements in renewables and green technologies contribute significantly to long-term development without impacting the environment. This study examines the relationship between CO2 emissions, energy consumption, GDP, renewable energy consumption, and technology innovations in G-7 countries. The results show that GDP and renewable energy consumption are inversely related to CO2 emissions. Technology innovations have both negative and positive impacts on CO2 emissions in the short and long term respectively. Considering green technologies in different sectors is crucial for a sustainable environment. Wavelet coherence analysis reveals a causality relationship between CO2 emissions and technology innovation in Italy, Japan, the UK, and the USA.

The combination of both processes proves to be more effective than adsorption and ozonation alone. Ozonation improves the adsorption performance of poorly-oxidizable CECs but worsens that of well-oxidizable compounds. This research highlights the importance of considering both processes in the removal of CECs in drinking water treatment plants.

China has adopted sponge city as an efficient means of preventing and controlling urban floods. Using a SWMM-FVCOM model, the hydrological reduction and control effect of sponge city construction (SPCC) within a university campus were evaluated. The study found that implementing SPCC effectively mitigates surface runoff and reduces the severity of urban flooding. However, the efficacy of runoff control decreases with longer rainfall return periods.
