Immobilizing of zero-valent iron in mono- and bi-metallic systems on the bentonite clay surface as new nanocatalyst were synthesized and used to degrade model acidic dyes from aqueous media. The Fourier-transform infrared spectroscopy, scanning electron microscopy-energy dispersive X-ray spectroscopy, transmission electron microscopy, X-ray diffraction, and Brunauer-Emmett-Teller analysis were ...

While process technologists are obsessed to follow Moore’s curve down to nanoscale dimensions, design technologists are confronted with gigascale complexity. On the other hand, post-PC and post dotcom products require zero cost, zero energy yet software programmable novel system architectures to be sold in huge volumes and to be designed in exponentially decreasing time. How do we cope with the...

The theory for current fluctuations in ac-driven transport through nanoscale systems is put forward. By use of a generalized, non-Hermitian Floquet theory we derive novel explicit expressions for the time-averaged current and the zero-frequency component of the power spectrum of current fluctuations. A distinct suppression of both the zero-frequency noise and the dc current occurs for suitably ...
