Nano-Opto-Electro-Mechanical Systems

A new class of hybrid systems that couple optical, electrical and mechanical degrees of freedom in nanoscale devices is under development in laboratories worldwide. These nano-opto-electro-mechanical systems (NOEMS) offer unprecedented opportunities to dynamically control the flow of light in nanophotonic structures, at high speed and low power consumption. Drawing on conceptual and technological advances from cavity optomechanics, they also bear the potential for highly efficient, low-noise transducers between microwave and optical signals, both in the classical and quantum domains. This Progress Article discusses the fundamental physical limits of NOEMS, reviews the recent progress in their implementation, and suggests potential avenues for further developments in this field.Comment: 27 pages, 3 figures, 2 boxe

Vanadium(III) Complexes of 1,4-Bis-[(5-H/methyl/chloro)-2-[H-Benzimidazolyl]-1,2,3,4-butanetetraols

1,4-Bis-[(5-H/methyl/chloro)-2-1H-benzimidazolyl]-1,2,3,4-butanetetraols (L1, L2 and L3) with VCl3 were synthesized and characterized using elemental analysis, molar conductivity, IR, H-1 and C-13-NMR spectroscopy. The ligands act as bidentate, coordinating through only two hydroxyl oxygen atoms in M:L 1:2 ionic and diamagnetic complexes
