In one aspect, composite particles are described herein. A composite particle comprises a substrate, composite metallic or metal oxide nanoparticles supported by the substrate and an amphiphilic or hydrophilic component associated with the substrate, wherein the composite metallic or metal oxide nanoparticles comprise iron and at least one additional transition metal.

Composite zero valent iron nanoparticles and applications thereof

An apparatus includes a laser source configured to output laser light at a target frequency, and a measurement unit configured to measure a deviation between an actual frequency outputted by the laser source at a current period of time and the target frequency of the laser source. The apparatus includes a feedback control unit configured to, based on the measured deviation between the actual and target frequencies, control the laser source to maintain a constant frequency of laser output from the laser source so that the frequency of laser light transmitted from the laser source is adjusted to the target frequency. The feedback control unit can control the laser source to maintain a linear rate of change in the frequency of its laser light output, and compensate for characteristics of the measurement unit utilized for frequency measurement. A method is provided for performing the feedback control of the laser source.

An exemplary optical limiter device () has an optically transmissive substrate () and a layer () on a first surface () of the substrate, the layer having a trimetallic nitride endohedral metallofullerene. The layer can be a thin film of the trimetallic nitride endohedral metallofullerene, a layer material with a cavity containing a solution with the trimetallic nitride endohedral metallofullerene, a sol-gel with a trimetallic nitride endohedral metallofullerene, and a self assembled monolayer with a trimetallic nitride endohedral metallofullerene. The layers of trimetallic nitride endohedral metallofullerenes can be vapor deposited, solution deposited and/or self assembled onto optical components. The third-order nonlinear properties of these films provide desired transmission characteristics.
