An entry from the Cambridge Structural Database, the world’s repository for small molecule crystal structures. The entry contains experimental data from a crystal diffraction study. The deposited dataset for this entry is freely available from the CCDC and typically includes 3D coordinates, cell parameters, space group, experimental conditions and quality measures.

In this paper, we develop an environmentally friendly, one-pot strategy toward rapid preparation of Ag nanoparticle-decorated reducd graphene oxide (AgNPs/rGO) composites by heating the mixture of GO and AgNO(3) aqueous solution in the presence of sodium hydroxide at 80 °C under stirring. The reaction was accomplished within a short period of 10 min without extra reducing agent. As-synthesized AgNPs/rGO composites have been successfully applied in photocurrent generation in the visible spectral region.

By conductivity method were examined the aggregation behavior of cationic amphiphile–cetyltrimethylammonium bromide (CTAB) and anionic amphiphile–sodium dodecyl sulfate (SDS) mixtures in binary mixtures of various salts. The values of critical micelle concentration (cmc) of SDS–CTAB mixtures lie between the cmc values of the pure amphiphiles. With temperature increasing the cmc values decrease first and then enhance with further rise of the temperature. The observed cmc of the SDS–CTAB mixed systems in attendance of binary mixture of salts was obviously less as compared to aqueous solution. The degree of counterion dissociation along with cmc value was utilized to evaluate different thermodynamic parameters. The values of interaction parameters and excess free energy were found to be negative in all cases. All results obtained reveal the strong interaction between the studied amphiphiles.

The appearance of the contagious virus COVID-19, several revelations and environmental health experts punctually predicted the possibly disastrous public health complications of coexisting catching and airborne contamination-arbitrated disease. But much attention has been given on the outdoor-mediated interactions. Almost 3.8 million premature deaths occur every year globally due to the illness from indoor air pollution. Considering the human staying longer span indoors due to restricted human activities or work from home, the indoor air quality (IAQ) might show prominent role for individual health life. Currently, the Environmental Protection Agency (EPA) ensures no regulation of indoor airborne pollution. Herein, the paper underlines the common bases of indoor air pollution, poor IAQ, and impacts of the aerosolized airborne particles on the human health. In order to address these challenges and collective contagion events in indoor environment, several emerging control techniques and preventive sustainable solutions are suggested. By this, more innovations need to be investigated in future to measure the impact of indoor air pollution on individual health.

Currently, NH₃ production primarily depends on the Haber-Bosch process, which operates at elevated temperatures and pressures and leads to serious CO₂ emissions. Electrocatalytic N₂ reduction offers an environmentally benign approach for the sustainable synthesis of NH₃ under ambient conditions. This work reports the development of biomass-derived amorphous oxygen-doped carbon nanosheet (O-CN) using tannin as the precursor. As a metal-free electrocatalyst for N₂ -to-NH₃ conversion, such O-CN shows high catalytic performances, achieving a large NH₃ yield of 20.15 μg h^-1 mg^-1 _cat. and a high Faradic efficiency of 4.97 % at -0.6 V vs. reversible hydrogen electrode (RHE) in 0.1 m HCl at ambient conditions. Remarkably, it also exhibits high electrochemical selectivity and durability.
