A comparative study has been made of iodine-intercalated Bi2Sr2Ca1Cu2Ox single crystal and 1 atm O2 annealed Bi2Sr2Ca1Cu1Ox single crystal using an AC susceptibility measurement, X-ray photoemission (XPS) and angle-resolved ultraviolet photoemission spectr ...
A novel type of difference spectroscopy is proposed to improve two-dimensional exchange spectroscopy by reducing diagonal peaks which are often dominant in complex cases such as in 2-dimensional nuclear Overhauser effect spectra of biopolymers. The diagona ...
A photolytic system comprised of a darkened halfcell and an illuminated halfcell in which oxidation and reduction reactions are made to occur. These halfcells are joined by an electrically conductive element and an ion conducting junction for electron tran ...
Using constrained ab initio molecular dynamics, we investigate the reaction of the O-2 molecule at the Si(100)-SiO2 interface during Si oxidation. The reaction proceeds sequentially through the incorporation of the O-2 molecule in a Si-Si bond and the diss ...
Four new Ru polypyridyl complexes with mono- or di((2-thienyl)ethenyl) substituted bipyridines were synthesized. The complexes were characterized by NMR, elemental anal., UV-visible absorption and electrochem. (differential pulse and cyclic voltammetry). E ...
We report UV and visible mol. ion-pair emission upon 193 nm excitation of I2 in solid xenon. By comparison to mol. emission obsd. in Kr matrixes, it is assigned to the d(2u)->2g (I*+I) and d(2u)->2g (I+I) transitions. The solvation energy of this charge tr ...
Synthetic boron doped diamond electrodes and microelectrodes were manufd. with techniques usually utilized in microelectronics: HFCVD coating, optical photolithog. and plasma etching. These electrodes were characterized in terms of their electrochem. prope ...
A first-principles investigation of Si 2p core-level shifts at the Si(001)-SiO2 interface is presented. We introduce several relaxed interface models obtained by attaching different crystalline forms of SiO2 to Si(001). These model structures contain the m ...
The photodissocn. I2M + hn -> I2 + M was studied for M = C2H6 and M = (C2H5)2O with excitation above the dissocn. limit of I2B state. Vibrational population distributions of the I2(B) product mols. are reported. The results are compared to previous studies ...
