ABSTRACT The existence of organic pollutants in aqueous media has become a vital issue and critical threat to human health, where toxic dyes represent the major contaminants wastewater. Over past few years, photocatalytic techniques have garnered lot interest dye removal from In this study, series Er x Tb Zn 1 − 2 O nanophotocatalysts (where = 0.00, 0.01, 0.03, 0.05) were synthesized coded as ZET0, ZET1, ZET2, ZET3 NPs (nanoparticles). chemical physical characteristics investigated using Fourier‐transform infrared spectroscopy (FT‐IR), X‐ray diffraction (XRD), photoelectron (XPS), transmission electron microscopy (TEM), energy‐dispersive (EDX) spectroscopy, ultraviolet–visible diffuse reflectance (UV–vis DRS) techniques. Further examination by performing experiments, ZET1 demonstrated effective Rhodamine B (RhB) degradation within 60 min. It was found that kinetic rate constant values 0.008, 0.097, 0.050, 0.040 min −1 for NPs, respectively. Aside their remarkable efficiency, these photocatalysts are highly stable even after five consecutive cycles. addition, active species test revealed primary oxidation involved process holes (h + ) hydroxyl radicals (•OH), possible mechanism degrading RhB tentatively proposed. enhancement efficiency is due low recombination photogenerated charge carriers, well strong synergistic impact Tb, Er, ZnO components. Thus, current study could offer versatile strategy design new nano wastewater purification future.

Air pollution in the environment is growing daily as a result of urbanization and population growth, which causes numerous health issues. Information about air quality environmental risks provided by pollutant data crucial for management. The use artificial neural network (ANN) approaches predicting pollutants reviewed this research. These methods are based on several forecast intervals, including hourly, daily, monthly ones. This study shows that ANN techniques contaminants more precisely than traditional methods. It has been discovered input parameters architecture-type algorithms used affect accuracy prediction models. therefore accurate reliable other empirical models because they can handle wide range meteorological parameters. Finally, research gap networks identified. review may inspire researchers to certain extent promote development intelligence prediction.

Organic-inorganic hybrid perovskite solar cells have made tremendous breakthroughs in device photovoltaic performance, but the solution chemistry features are poorly understood. Herein, fundamental processes of crystal crystallization and several templates for growth described. Then solvent systems preparing thin films introduced, including pure, binary, ternary solvents. The interaction precursor ligand molecules solution, which is related to nature intermediate phase, dependent on distinct molecules, dimethylformamide (DMF), N-methyl-2-pyrrolidone (NMP), dimethyl sulfoxide (DMSO), acetonitrile (ACN), urea, etc. polarity determines degree binding Pb2+ stability complex, affects quality films. In engineering research field, strong polar solvents will interact with Pb2+, leads extensive study phases. this review, typical phases summarized as solvent-induced intermediates, HI MA intermediates MAAc intermediates. annealed or antisolvent treated further form films, resulting low defects, high-quality few pinholes. On basis, we propose use green instead toxic preparation by multi-solvent systems, provides some feasible ideas realization high-performance long-term stability.

The tribo-performance of passenger car engine oil with three friction modifiers (organic and inorganic) has been experimentally evaluated using benchtop tribometers. Friction coefficient traces wear contact potential (qualitative measurement lubricating film formation) were reported at varying pressures, speeds, temperatures. in situ film-forming characteristics modifier also investigated SLIM (Spacer layer imaging) a Mini traction tribometer. Overall, inorganic (MoDTC) yielded better tribological performances than organic modifiers. Typically, thicker protective tribo-film (180 nm) formed the worn surface by MoDTC (80–120 nm). Scanning electron microscopy (SEM), Raman spectroscopy Atomic force (AFM) have utilised to characterise surfaces understand mechanism behind formation.
