The current exploration focuses on the impact of homogeneous and heterogeneous chemical reactions titanium dioxide-ethylene glycol (EG)-based nanoliquid flow over a rotating disk with thermal radiation. In this paper, horizontal uniform magnetic field is used to regularise produced by disk. Further, we conduct comparative study fluid without aggregation. Suitable transformations are convert governing partial differential equations (PDEs) into ordinary (ODEs). Later, attained system solved...

A new nano-silica/chitosan (SiO2/CS) sorbent was created using a wet process to eliminate uranium(VI) from its solution. Measurements BET, XRD, EDX, SEM, and FTIR were utilized analyze the production of SiO2/CS. The adsorption progressions carried out by pH, SiO2/CS dose, temperature, sorbing time, U(VI) concentration measurements. optimal condition for sorption (165 mg/g) found be pH 3.5, 60 mg SiO2/CS, 50 min 200 mg/L U(VI). Both second-order kinetics Langmuir model observed obeyed ability...

In this present work, a PVA/PVP-blend polymer was doped with various concentrations of neodymium oxide (PB-Nd+3) composite films using the solution casting technique. X-ray diffraction (XRD) analysis used to investigate structure and proved semi-crystallinity pure PVA/PVP polymeric sample. Furthermore, Fourier transform infrared (FT-IR) analysis, chemical-structure tool, illustrated significant interaction PB-Nd+3 elements in blends. The transmittance data reached 88% for host blend matrix,...

Abstract The present research aims to predict effluent soluble chemical oxygen demand (SCOD) in anaerobic digestion (AD) process using machine-learning based approach. Anaerobic is a highly sensitive and depends upon several environmental operational factors, such as temperature, flow, load. Therefore, predicting output characteristics modeling important not only for monitoring control, but also reduce the operating cost of treatment plant. It difficult COD real time mode, so it better use...
