Humans perceive a portion of the electromagnetic wave spectrum known as the eponymic “visible light spectrum.” Waves in the visible light spectrum range from ∼400nm (violet) to ∼700nm (red). The biology of the eye, or specifically the retina, which is where the field of light recep...
photocatalysis. Heterogeneous photocatalysis has been exploited for the mineralization and degradation of a wide variety of organic contaminants in these processes8,9,10. Numerous catalysts, including TiO2, ZnO, ZnS, Al2O3, Fe2O3, and CdS, have been employed for this purpose8. ZnO material, on...
A frequency comb is a source with a spectrum that contains a series of equally-spaced frequency lines. Another χ(3) effect is the Kerr effect, in which high-intensity light induces a refractive index change in the material (given by n=n0+n2I)n=n0+n2I), which results in self-phase ...
INTERSTITIAL hydrogen generationSUSTAINABILITYCLEAN energyVISIBLE spectraCIRCULAR economyPhotocatalytic processes offer promising solutions for environmental remediation and clean energy production, yet their efficiency under the visible light spectrum remains a significant challenge. Here, we report a novel silver...
(EDX). The adsorption and photodegradation under the visible light irradiation of methylene blue (MB) were studied for TiO2, TCPP/TiO2, TCPP/CuPOM/TiO2and TCPP/ZnPOM/TiO2thin films in aqueous solution. The results of the diffuse reflectance showed two bands in the visible light spectrum for ...
On July 27, 2018, New York's Public Service Commission ordered Charter Communications out of the state. The frustration that Charter's Spectrum cable service failed to expand broadband access and deliver full speed connections to existing broadband customers has led the commission to cancel the firm...
In order to advance in the field of hydrogen technology, it is essential to possess a comprehensive understanding of thermophysics. Different types of catalysts are utilized in the treatment of advanced oxidation process (AOPs). AOPs are based on physicochemical reactions that alter molecular ...
