Copper defects inside AlN:Cu nanorods – XANES and LAPW study

Copper speciation in size-fractionated aerosol samples using TXRF-XANES

The health effects of aerosol depend on the size distribution and the chemical composition of the particles. Heavy metals of anthropogenic origin are connected to the fine aerosol fraction (PM2.5). The composition and speciation of aerosols can be variable in time, due to the time-dependence of anthropogenic sources as well as meteorological conditions. Synchrotron-radiation total-reflection X-...

Xanes/exafs Study of the Copper Active Site in Methanol Synthesis Catalyst

Measurements of the Oxidation State of Manganese inside Brain, Heart, and Liver Mitochondria using XANES Spectroscopy

Most intracellular Mn is found in mitochondria. We have used the shift in the manganese absorption edge in x-ray absorption near edge structure (XANES) spectroscopy to determine the oxidation state of Mn in brain, heart, and liver mitochondria, as well as in PC12 cells. We compared the XANES spectra of Mn in brain, heart, and liver mitochondria over a range of Mn concentrations with those of Mn...

Photonic nanorods with magnetic responsiveness regulated by lattice defects.

Herein, we use experiments and numerical simulations to demonstrate a novel class of magnetically responsive photonic crystals (MRPCs) based on photonic nanorods which exhibit multiple optical properties in a magnetic field (H) due to their fixed photonic nanorods and H-tunable lattice defects. As an example, superparamagnetic Fe3O4@polyvinyl pyrrolidone (PVP)@SiO2 photonic nanorods were fabric...
