As shown in Fig. 7a, Nd-doped NiAl catalytic nanoparticles on the surface of NdFeB magnetic nanoparticles over Fe foam, exhibited a much higher CO conversion rate than the single mode catalysts, including the as-synthesized NdNiAl nanoparticles, the conventional NiAl RANEY nanoparticles and the as-fabricated NdFeB nanoparticles over the same Fe foam.(More…)

High-sensitivity Cameras Reveal the Atomic Structure of Metal-organic Frameworks

A method for fine-scale imaging of a class of materials that is useful for gas storage and separation is needed. However, typical visualization methods emit an electron dose that can cause damage to the structure of some materials.

One such material is called metal–organic frameworks (MOFs), three-dimensional structures made up of metal ions connected by organicligands. MOFs are useful for gas…

KEY TOPICS

Based on these assays, it can be concluded that the toxic effects observed with various industrial nanoparticles will not be observed with particles made of synthetic polymers such as PLGA when applied in the field of nanomedicine.(More…)
