Density functional theory simulations show that modifying rutile TiO(2) with metal oxide nanoclusters produces composite materials with potential visible light photocatalytic activity.

automobile body plays crucial role in preventing the collision energy transfer in severe accidents to the passengers. if the collision energy is dissipated or saved in bumper or chassis, the amount of damage to the occupants would be minimized. using novel laminated panel (fiber metal laminate) in auto body, and considering the characteristics such as high energy absorption, strength, high dent...

Nanostructures of noble metal materials have been used in organic solar cells for enhancement of performance and light trapping. In this study, we have introduced branched silver cauliflower-like nanopatterns as sub-wavelength structured metal grating in organic solar cells. Self-assembled fabrication process of branched nanopatterns was carried out on a bio-template of cicada wing nanonipple a...

objectives: the aim of this study was to evaluate the effect of conventional and high-power light emitting diode (led) light curing units on shear bond strength (sbs) of metal and ceramic brackets to tooth surface. materials and methods: forty sound bovine maxillary central incisors were used for the study. the teeth were divided into four groups (n=10). teeth surfaces were etched with 37% phos...

The photocurrent conversions of transition metal dichalcogenide nanosheets are unprecedentedly impressive, making them great candidates for visible range photodetectors. Here we demonstrate a method for fabricating micron-thick, flexible films consisting of a variety of highly separated transition metal dichalcogenide nanosheets for excellent band-selective photodetection. Our method is based o...

Disordered noble-metal nanoparticle films exhibit highly localized and stable nonlinear light emission from subdiffraction regions upon illumination by near-infrared femtosecond pulses. Such hot spot emission spans a continuum in the visible and near-infrared spectral range. Strong plasmonic enhancement of light-matter interaction and the resulting complexity of experimental observations have p...

A hollow Fe2O3-TiO2-PtOx photocatalyst for visible light H2 generation was prepared from nanosized MIL-88B consisting of coordinatively unsaturated metal centers as a hard template. This photocatalyst is composed of hybrid metal oxide-TiO2 with controllable wall thickness and two different cocatalysts that are separately located on two surface sides.

An ultra-thin nanostructured plasmonic light absorber with an insulator-metal-insulator-metal (IMIM) architecture is designed and numerically studied. The IMIM structure is capable to absorb up to about 82.5% of visible light in a broad wavelength range of 300-750 nm. The absorption by the bottom metal is only 6% of that of the top metal. The results show that the IMIM architecture has weak dep...
