Metallic oxide nanocrystals with near-infrared plasmon resonance for efficient, stable and biocompatible photothermal cancer therapy.

Photothermal therapy is regarded as one of the most promising cancer treatment technologies due to its negligible side effects and fast operation. However, its therapeutic efficacy is still limited by the lack of cost-effective photostable and biocompatible therapeutic agents with efficient light absorption in the biological window. Here, taking MoO as an example, we propose oxide nanocrystals (NCs), with both a metallic electronic structure and near-infrared (NIR) plasmon resonance, for efficient, stable and biocompatible photothermal cancer therapy.

Assembling tungsten oxide hydrate nanocrystal colloids formed by laser ablation in liquid into fast-response electrochromic films.

High-performance electrochromic films based on tungsten oxide hydrate ([WO(O)HO]·1.66HO) colloidal nanocrystals with fast switching speed were fabricated by laser ablation in a mixture of water and hydrogen peroxide followed by electrophoretic methods. Through electrophoretic deposition, the nanoparticles in the colloids synthesized by laser ablation aggregated onto the FTO coated glass substrate forming a lager cell with a uniform size of around 200nm, which subsequently self-assembled into a porous tungsten oxide hydrate film.

[Experimental investigation on sulfur emission properties of micro-pulverized coal].

Micro-pulverized coal(0-20 microns) combustion is a new kind of pulverized coal combustion technology. Four Heshan sulfur coal samples with different mean particles diameter were combusted, using a TGA-FTIR made in Germany. Micro-pulverized coal self-desulfurization and adding CaO desulfurization characteristics were investigated.
