The nanostructured Ce ion substituted cryptomelane-type octahedral molecular sieve (OMS-2) catalyst exhibits strong absorption in the entire solar spectrum region. The Ce ion substituted OMS-2 catalyst can efficiently transform the absorbed solar energy to thermal energy, resulting in a considerable increase of temperature. By combining the efficient photothermal conversion and thermocatalytic ...

In this paper, a novel solar solid dehumidification/regeneration bed has been proposed, and its three regeneration methods, i.e., simulated solar radiation regeneration, microwave regeneration, and combined regeneration of the microwave and simulated solar radiation, were experimentally investigated and compared, as well as the dehumidification performance. The degree of regeneration of the pro...

The Martian regolith is exposed to solar irradiation in the near-UV (200-390 nm). Basalt is one of the main components of the dust on Mars surface. The near-UV irradiation of basalt dust on Mars is simulated experimentally in order to determine the transmittance as a function of the mass and thickness of the dust. This data can serve to quantify the absorption of dust deposited on sensors aimin...

in this study, a novel magnetic nanocomposite (ba-α-bi2o3-γ-fe2o3) was successfully synthesized through a combination of ultrasound and co-precipitation method under mild conditions. the structure of the synthesized nano-composite as a visible light photocatalyst was investigated by the xrd, tem, hrtem, uv-vis and ft-ir. the hrtem confirmed that the nano-magnetic composites are rods with diamet...

This study addresses the preparation and characterization of hybrid films prepared from Titanium dioxide (TiO2) Pickering stabilized acrylic polymeric dispersion as well as their bacterial inactivation efficiency under sunlight irradiation. Complete bacterial inactivation under low intensity simulated solar light irradiation (55 mW/cm(2)) was observed within 240 min for the films containing 10 ...

Ternary polymer solar cells based on a PTzBT have received lot of attention because their power conversion efficiency (PCE) and thermal stability been greatly improved by adding small amount an oligomer ITIC. However, the charge-accumulation states ternary not yet completely clarified. Here, we report electron spin resonance (ESR) spectroscopy to investigate from microscopic viewpoint with exam...

A WO(3)/TiO(2) composite is constructed with the ability to degrade organic molecules under visible irradiation, which is newly explored by UV pre-irradiation. The long lasting visible-light photoactivity and the consecutive photocatalytic process will benefit the efficient use of solar energy.

TiO2 nanotubes arrays (NTs), obtained via electrochemical anodization of Ti foil, were modified with monometallic (Cu, Bi) and bimetallic (AgCu) nanoparticles. Different amounts of metals' precursors were deposited on the surface of NTs by the spin-coating technique, and the reduction of metals was performed via gamma radiolysis. Surface modification of titania was studied by EDS and XPS analys...

Irradiation of aerosols of either Escherichia coli or Serratia marcescens with simulated solar (xenon) radiation caused a significant decrease in viability. When sodium fluorescein was employed to determine the physical loss of organisms from the aerosol, an additional adverse effect upon survival was noted. The decay curves indicated that at least two mechanisms of inactivation were operative,...

The photocorrosion of a nanoporous carbon photoanode, with low surface functionalization and high performance towards the photoelectrochemical oxidation of water using simulated solar light, was investigated. Two different light configurations were used to isolate the effect of the irradiation wavelength (UV and visible light) on the textural and chemical features of the carbon photoanode, and ...
