A novel chromogenic calix[4]arene 3, which has within a molecule both the triazoles and the hydroxyl azophenols as the metal-binding sites and the azophenol moiety as a coloration sites was designed and synthesized. Calix[4]arene 3 is highly sensitive to Ca2+ and Pb+ ions, which can be detected by the naked eye. Furthermore, the association constants for the 1:1 complexes of 3 center dot Ca2+ and 3 center dot Pb2+ were determined to be 7.06 x 104 M-1 and 8.57 x 103 M-1, respectively. (c) 2007 Elsevier Ltd.

The concept of the intermediate band (IB) solar cells (SC) offers the promise of achieving 63% conversion efficiency devices. The effect of the type II band alignment in the quantum dot (QD) IB SCs on the above percentage is analyzed and the potential of the Ge/Si system for fabrication of the type II QD IB SC is discussed. Also, it is shown that the increase of the sunlight concentration leads to the rise of the potential barrier around QDs and the concentration of S-x approximate to 700 can induce the epsilon(L) = 0.2 eV height barrier in the Ge/Si system, making this a significant result. Furthermore, the increase of the sunlight concentration leads to the separation of the quasi-Fermi levels from the confined states and also leads to the decrease of the recombination activity in QDs. The two-photon absorption in QDs increases rapidly and dominates over recombination at the moderate concentration. As the contributions of QDs to both the photo- and dark currents in the type II QD IB SC are evaluated it is shown that, compared to the conventional Si SCs, the type II Ge QD IB Si SCs can generate about 25% higher photocurrent and conversion efficiency.
Structural and optical properties of In-rich InGaN nanodots grown by metallo-organic chemical vapor deposition

The surface morphologies, alloy compositions and emission properties of In- rich InxGa1-xN nanodots ( x >= 0.87) grown by metallo-organic chemical vapor deposition at various growth temperatures (550-750 degrees C) were investigated. We found that the nucleation of InGaN dots was dominated by the surface migration of In adatoms. A higher Ga content can be achieved at lower growth temperatures due to the relatively lower migration ability of Ga adatoms. At higher growth temperatures, the InGaN dots tend to decompose into In- rich islands and a thin Ga-rich layer. These In- rich islands exhibit photoluminescence emission in the near-infrared range. Another visible emission band was also observed for samples grown at higher temperatures. The formation of a thin Ga-rich layer is likely to be responsible for the visible emission.
Surface-metallized polyimide material and method for manufacturing the same

Hsiao, Yu-sheng
A method for manufacturing a surface-metallized polyimide material includes performing an alkaline treatment on a surface of a polyimide material to cause ring opening of the polyimide material on the surface; the surface of the polyimide material being subject to an ion exchange process for being displaced by a first metal ion exclusive of palladium ion, gold ion, silver ion, and copper ion; and performing a wet reduction process to reduce the first metal ion on the surface of the polyimide material into a first metal that adheres to the surface of the polyimide material. A surface-metallized polyimide material produced according to the aforementioned method is also disclosed.
