Analysis of solitary wave solutions in the fractional-order Kundu-Eckhaus system.

The area of fractional partial differential equations has recently become prominent for its ability to accurately simulate complex physical events. The search for traveling wave solutions for fractional partial differential equations is a difficult task, which has led to the creation of numerous mathematical approaches to tackle this problem. The primary objective of this research work is to provide optical soliton solutions for the Frictional Kundu-Eckhaus equation (FKEe) by utilizing generalized coefficients.

Rational design of full-spectrum visible-light-responsive bimetallic sulfide BiS/CoS composites for high-efficiency photocatalytic degradation of naproxen and bacterial inactivation.

Photocatalytic water decontamination has emerged as a highly promising technology for efficient and rapid water treatment, harnessing sustainable solar energy as its driving force. In this study, we prepared visible-light active BiS/CoS composites for the degradation of naproxen (NPX) and the inactivation of Escherichia coli (E. coli).

A novel discrete-time COVID-19 epidemic model including the compartment of vaccinated individuals.

Referring tothe study of epidemic mathematical models, this manuscript presents a noveldiscrete-time COVID-19 model that includes the number of vaccinated individuals as an additional state variable in the system equations. The paper shows that the proposed compartment model, described by difference equations, has two fixed points, i.e.

Construction of g-CN/CdS/BiVO ternary nanocomposite with enhanced visible-light-driven photocatalytic activity toward methylene blue dye degradation in the aqueous phase.

Herein, the ternary CdS/BiVO/g-CN (CBG) hybrid semiconductor photocatalyst was prepared via a hydrothermal technique. The synthesized photocatalysts were thoroughly characterized using powder XRD, XPS, FTIR, SEM, TEM, and UV-DRS to investigate the microstructural, morphological attributes, and optical properties. The photocatalytic activity of the ternary CBG hybrid semiconductor was assessed through the photodegradation of Methylene Blue (MB) aqueous dye under visible light.

MWCNT supported VO quantum dot nanoparticles decorated BiO nanosheets hybrid system: Efficient visible light driven photocatalyst for degradation of ciprofloxacin.

A novel composite of multiwall carbon nanotube (MWCNT) supported VO quantum dots decorated BiO hybrid was prepared by the simple wet-impregnation method, and the photocatalytic performance of the prepared samples was investigated against the photodegradation of ciprofloxacin (CIP). Herein, different samples of pristine, VO/BiO and MWCNT@VO/BiO hybrid photocatalyst were prepared and systematically characterized by various physicochemical techniques. The characterization results demonstrated that the introduction of MWCNT can change the energy band gap of VO/BiO, and the band energies vary with a constituent of MWCNT@VO/BiO catalyst, in which MWCNT@VO/BiO-5 (0.
