The aim of this study was to design and characterize a NdFeO3-based photocatalyst prepared by sol-gel method for treatment of oily wastewater. Different characterization techniques such as X-ray diffraction (XRD), scanning electron microscope (SEM), Fourier transform infrared spectroscopy (FTIR), UV–vis spectrophometer were used to elucidate the structure, morphology, surface functional groups, and optical absorption properties of the prepared NdFeO3 photocatalyst.

This study employs the tight-binding density functional method GFN1-xTB to investigate the structural and electronic properties of TiO2-ZnO and TiO2-ZnO composite materials modified by Li, Na, K, and Fe metals. Computational analyses reveal the formation of weak covalent bonds between the TiO2 and ZnO components within the composite system. Doping TiO2-ZnO with metals induces significant alterations in the electronic structure, particularly in terms of ionization energy and global electrophilic index.

In this paper, free vibration of bidirectional functionally graded sandwich (BFGSW) beams is studied by using a finite element formulation. The beams made from three distinct materials are composed of three layers, a homogeneous core and two bidirectional FGM face layers with material properties varying in both the thickness and longitudinal directions by power gradation laws.

The geometries and relative stabilities of 15 tautomeric forms and the corresponding isomers of the studied molecules have been identified and their relative stabilities are investigated. The potential energy profiles and intrinsic reaction coordinates (IRC) calculations along the proton transfer coordinates both in the ground and in the excited state are monitored as well. The impact of the donating (OMe) and withdrawing (NO2) groups on the single and double proton transfers are investigated both in the gas phase and solution.

This paper presents a method for establishing the exact receptance function of a tapered axially functionally graded (AFG) beam with nonlinear ratios of properties using the Adomian method. In current papers, the Adomian method was applied for linearly tapered beams where the geometric series was used conveniently.

While it is recognised that knitted fabrics may have their place in firefighting PPC, especially for undergarments, from the point of view of fire performance, strength and presentation, woven fabric constructions appear to be more suitable for work wear applications. Hence, this study is concerned with developing and testing a range of functional, woven Station Wear fabrics designed to enhance flame protection, durability and thermo-physiological comfort properties. In trying to improve all three aspects, a compromise in the properties of fabrics developed would be very likely.

The recent advances in the study of the unique capabilities of monolayer crystals had predicted piezoelectricity in two-dimensional (2D) group IV chalcogenides which are not present in their bulk forms. In this study, the predicted piezoelectric properties of was experimentally explored through Piezoelectric Force Microscopy (PFM). Tin Sulfide (SnS), Tin Selenide (SnSe), Germanium Sulfide (GeS), were exfoliated from their bulk forms by the top down methods of liquid sonication, while and Tin Disulfide (SnS2) mechanically exfoliated by tape.

The major protein fraction in pearl millet is prolamin the alcohol soluble fraction called pennisetin. Researches on the factors affecting pennisetin extraction and on its functional properties are still very scant. In this paper, the effect of temperature, reducing agents (β-mercaptoethanol, dithiothreitol or sodium metabisulfite) and sodium hydroxide on pennisetin extraction was assessed.
