Ag–Au bimetallic nanocomposites stabilized with organic–inorganic hybrid microgels: synthesis and their regulated optical and catalytic properties

“…[11][12][13] Among the multitude of bimetallic NPs, Ag-Au ones have attracted increased attention due to the high extinction coefficient and electronegativity of Ag NPs and the high chemical stability and biological activity of Au NPs. 14,15 The similarity between the lattice spacings of Ag and Au allows the fabrication of Ag-Au bimetallic nanocrystals with tunable morphology, 16 and the optical performance of Ag-Au NPs can be regulated by adjusting their structure and the relative contents of Ag and Au. 17,18 Compared to the co-reduction approach, the galvanic replacement (GR) reaction strategy had received more attention due to offering facile reaction conditions and allowing the fabrication of bimetallic NPs with tunable structures that can be controlled by adjusting the concentration ratio of metal precursor salts.…”

Strong Eddy-Current Shielding of Ferromagnetic Resonance Response in Sub-Skin-Depth-Thick Conducting Magnetic Multilayers

“…The similarity of the far-and near-field responses is very important, e.g., for experimental characterisation of magnetic meta-materials. [5][6][7][8][9][10] Note that the far-field and near-field responses are similar, provided the stripline width is large enough as in our experiment. The requirement of a large stripline width ensures the absence of the adverse effect of travelling spin wave contribution to the FMR response 27 and should be fulfilled in any BFMR experiment.…”

“…1 Consequently, there is a huge interest in the excitation, detection and control of spin waves at the nano-scale, 2 as well as in a number of spintronic effects such as the spin transfer torque, direct and inverse Spin-Hall effects, and spin pumping. 3,4 A deep understanding of physics of these effects is crucial for the development of novel devices that include but not limited to: magnetic random access memory (MRAM), spin-torque MRAM, spintorque nano-oscillators, 1,3 frequency-agile left-handed meta-materials [5][6][7][8][9][10] , as well as gas sensors. 11 The aforementioned devices operate at microwave frequencies and they are made of multilayers consisting of non-magnetic metal (NM) and ferromagnetic metal (FM) thin films.…”

Silber als antibakterielles Agens: Ion, Nanopartikel, Metall

“…[91] Für den gelegentlich vorgeschlagenen Einsatz als Wirkstoffträger und zur Bildgebung eignen sich Silber-Nanopartikeln wegen der vergleichsweise hohen Zytotoxizität aber wohl nur, wenn eine unkontrollierte Freisetzung toxischer Silberionen durch eine entsprechende dichte Umhüllung ausgeschlossen werden kann.
