Vector replacement rules allow formulation of the flowsnake planefilling curve as a bijection Z⟷Z2 and as a surjection ⟶2. The -function visits double and triple points predicted by Netto’s theorem. Triple points belong to a relatively simple set, while double points resist easy classification. This paper formulates and analyzes the -function. Methods applied to the flowsnake also apply to ...

In this work, we proposed to synthesize CuFe2O4/Fe2O3 core-shell materials with different Fe2O3 contents in order create new and efficient photo-Fenton-like catalysts for the degradation of methylene blue oxalic acid as a radical-producing source. The were prepared through two stages: first, CuFe2O4 was by hydroxide coprecipitation – annealing method then, immobilized on surface simple impregna...

nanoparticles of zirconium(iv) tungstate are prepared by chemical co-precipitation method. thecharacterizations have been carried out by tg/dta, dsc, afm, xrd, ftir and uv-vis spectrum. plspectrum shows two emission bands at 350 nm and at 477 nm. the effects of frequency on the dielectricbehavior and ac electrical conductivity have been studied. the dielectric constant is found to be 119.43 at1...

land and resource developoment suitability is usually achieved by landscape capability analysis. but using land capability analysis in planning process is often restricted by budget and time limitations. a simple yet effective capability analysis method is hence required, that can furnish 'planners reliable land zonning with the least data and time requirement. the optimum integration meth...

Plasmonic nonmetal semiconductors with localized surface plasmon resonance (LSPR) effects possess extended light-response ranges and can act as highly efficient H2 generation photocatalysts. Herein, an LSPR-enhanced 0D/2D CdS/MoO3?x heterojunction has been synthesized by the growth of 0D CdS nanoparticles on 2D plasmonic MoO3?x elliptical nanosheets via a simple coprecipitation method. Taking a...
