The move from planar CMOS-based microelectronics and advanced device structures like FinFETs and FD SOI structures to devices with 1-dimensional nanostructures (Si, Ge, III-V semiconductors) requires fundamental studies of nanostructures and innovative approaches to integrate the new materials and structures into microelectronic products. The approach of nanowire-devices for reconfigurable fiel...

Abstract Prunetin (4′,5-dihydroxy-7-methoxyisoflavone) was semisynthesized in 8 steps from readily available naringenin 26% total yield. The key reaction chemoenzymatic sequential deacetylation to 6′-acetoxy-2′,4″-dihydroxy-4′-methoxychalcone, the situ-formed precursor for thallium(III) nitrate-mediated oxidative rearrangement.

copper oxide nanostructures have been successfully synthesized via one-step solid-state thermolysis of two metal-organic frameworks, [cu3(btc)2] (1) and [cu(tpa).(dmf)] (2), (btc = benzene-1,3,5-tricarboxylate, tpa = therephtalic acid = 1,4-benzendicarboxylic acid and dmf = dimethyl formamide) under air atmosphere at 400,  500, and 600°c. it has also been found that the reaction temperature pla...

The different (structural and chemical) properties of oxide single-crystal surfaces that can be exploited for the growth of self-assembled oxide nanostructures are briefly reviewed. A large variety of nanostructures can be obtained, controlled by surface and interface structure and chemistry, which play a predominant role in their formation mechanisms at this nanometer scale. It is reminded tha...
