Cyanine dyes are fluorescent organic salts with intrinsic conductivity for ionic and electronic charges. Recently (J. Am. Chem. Soc. 2013, 135, 18008-18011), these features have been exploited in cyanine light-emitting electrochemical cells (LECs). Here, w ...
Large single crystals of the new magnetic solid RbNa3Fe7(PO4)6 can be grown in a salt flux. Below the ferro-to-antiferromagnetic transition temp. of 6 K, the field (H) dependence of the magnetization (M) of an oriented crystal of exhibits equally spaced st ...

By flaring a dielectric waveguide in the H-plane, an H-plane dielectric horn is formed, which could be directly excited by an SIW feed. However, matching and radiation performances are poor due to the thinness of the substrate. To improve these performance ...

Folded substrate integrated waveguide (FSIW) has been proposed for further size reduction, while keeping the advantages of traditional SIW. FSIW-based horn antennas are very promising in millimeter wave applications. To improve the bandwidth and efficiency ...
A novel substrate-integrated waveguide (SIW) horn antenna with partially detached broad walls is designed and analyzed. The conventional SIW horn antenna suffers from narrow-operating bandwidth, which mainly results from the mismatch at the horn aperture b ...
Ultrathin bilayer heterojunction solar cells using cyanine electron donors and electron acceptor C-60 are used to fabricate monolithically stacked tandem and triple junction devices. Sub-cell stack sequences as well as C-60 layer thicknesses are optimized ...

We recently reported a low-dimensional compd., RbNa3Fe7(PO4)6, that contains electronically confined magnetic nanostructures (Angew.Chem. Int. Ed. 2007, 46, 5344-5347). The field dependent magnetization plot of RbNa3Fe7(PO4)3 shows stepped variations at in ...
