TL;DR: In this article, the authors analyzed the properties of 2% tungsten oxide doped titania films and showed that they were the most effective photocatalysts for photocatalysis.
166 citations
TL;DR: In this article, the authors reviewed the experimental observations and theoretical understanding of the fracture behavior of tungsten in the brittle and semi-brittle regime and showed that dislocation nucleation is the limiting factor at low temperatures, while the dependence on loading rate at intermediate temperatures requires that dislocations mobility takes control.

TL;DR: It is demonstrated that the femtosecond laser blackening technique can even obtain partially polarized light as well as control the spectral range of the optimal light emission from the laser-blackened tungsten lamp.
Abstract: By applying the femtosecond laser blackening technique directly to a tungsten incandescent lamp filament, we dramatically brighten the tungsten lamp and enhance its emission efficiency to approach 100%. A comparison study of emission and absorption for the structured metal surfaces shows that Kirchhoff's law is applicable for the black metal. Furthermore, we demonstrate that we can even obtain partially polarized light as well as control the spectral range of the optimal light emission from the laser-blackened tungsten lamp.
