In this work, we perform a first-principle study to investigate the atomic and electronic structures of ${\mathrm{C}}_{3}{\mathrm{N}}_{4}/{\mathrm{MoSi}}_{2}{\mathrm{N}}_{4}$ van der Waals heterostructure (vdWH) as well its tunable structure via interlayer coupling an external perpendicular electric field. The vdWH is structurally thermodynamically stable at room temperature. Our results demonstrate that exhibits semiconducting characteristic with direct band gap 1.86/2.66 eV given by...
The sonochemical synthesis of a chitosan-ZnO/Fe3O4 nanocomposite yielded highly porous structure and large surface area for enhancing the photocatalytic degradation cationic (rhodamine B, RhB) anionic (methyl orange, MO) dyes in aqueous solution. Chitosan-ZnO/Fe3O4 demonstrated significant enhancement photodegradation efficiency 99.49% MO (C 0 = 5.32 mg L-1, t 150 min) 90.73% RhB 5.03 under visible light due to its narrow bandgap 2.84 eV. performance was investigated by varying pH, dye...
Ninh Binh province is known as an endemic area of fish-borne zoonotic trematode (FZT) transmission in Vietnam. A cross-sectional study was conducted Gia Minh and Thinh communes Vien district, to investigate the infections with different stages FZT various host species. Faecal samples from 1,857 humans were examined for eggs using Kato-Katz method, while faecal 104 dogs, 100 cats, pigs Formalin-ethyl acetate concentration technique (FECT). total 483 specimens freshwater fish, representing 9...
Moving from malaria control to elimination requires national programmes implement strategies detect both symptomatic and asymptomatic cases in the community. In order do this, follow up reported by health facilities carry out case investigations that will determine origin of infection, whether it has been imported or is due local transmission. If necessary, programme also active surveillance find additional locality prevent further To understand current practices share information on...
van der Waals heterostructures provide a powerful platform for engineering the electronic properties and exploring exotic physical phenomena of two-dimensional materials. Here, we construct graphene/BSe heterostructure examine its characteristics tunability contact types under electric fields. Our results reveal that is energetically, mechanically, thermodynamically stable at room temperature. It forms p-type Schottky exhibits high carrier mobility, making it promising candidate future...
This study presents an experiment on the impact of externally bonded carbon fiber-reinforced polymer (CFRP) sheets in strengthening large openings two-way reinforced concrete (RC) slabs. Five identical square RC slabs with dimensions 1200 mm × 60 were fabricated. All test had a large, centrallylocated opening 400 mm. One slab was unstrengthened control specimen,while four strengthened at using CFRP sheets. Two schemes studied:CRFP along sides and diagonal corners 45-degree angles. supported...
Abstract Pure BiFeO3 and (Gd, Co) co-doped samples were synthesized by a sol-gel method. The effects of co-doping on the crystal structure investigated using various techniques, such as X-ray diffraction, energy dispersive spectroscopy, fourier transform infrared magnetization hysteresis loops, ferroelectric loops. diffraction analysis confirmed that all exhibited rhombohedrally distorted cubic perovskite structure. Energy spectroscopy presence Bi, Fe, O, Gd Co atoms in same atomic weight...
In this study, the double hydrothermal method is proposed as a facile approach to synthesis of ZnTe/ZnO core–shell nanorods. The coating thickness p-type ZnTe varied adjust junction depth in n-type ZnO nanorods, and conductance measurements reveal change conduction path heterojunction structures. Structural chemical investigations conducted using X-ray diffraction, transmission electron microscopy, photoelectron spectroscopy confirm hetero-nanostructure formation ZnTe/ZnO. role H2S-gas...
