Since the introduction of the first consumer lithium ion battery (LIB) in 1991, it has become attracted considerable attention as a renewable energy source. Its demand is increasing yearly with increasing diffusion of a cell-phone and a laptop PCs, recently it is widely applied to not only small type but also middle-large type products such as hybrid vehicles. For the systematic, effective deve...
Use of photoelectron energy spectrum transfer equation for the measurement of a narrowband XUV pulse
Nearly 100 years ago, Moses Gomberg introduced the scientific community to the study of organic radicals,1 concluding this classic manuscript with the comment that, “This work will be continued and I wish to reserve the field for myself.” Gomberg’s studies of triphenylmethyl radical were only the beginning of intense research into the properties of the newly discovered trivalent carbon, and des...
A combination of experimental methods, photoelectron-imaging spectroscopy, flowing afterglow-photoelectron spectroscopy and the flowing afterglow-selected ion flow tube technique, and electronic structure calculations at the B3LYP/6-311++G(d,p) level of density functional theory (DFT) have been employed to study the mechanism of the reaction of the hydroxide ion (HO-) with 1H-1,2,3-triazole. Fo...
We have studied oxidation and reduction of ionic liquids using methods of theoretical chemistry. In particular, we have modeled photoelectron spectra of 1-ethyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide ([emim][Tf(2)N]) and 1-butyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide ([bmim][Tf(2)N]) ionic liquids and their components. We have considered ion pairs in the gas phase ...
In this paper, we theoretically demonstrate that the (2+1+1) resonance enhanced multi-photon ionization photoelectron spectroscopy in sodium atom can be effectively controlled by shaping femtosecond laser pulse with a π phase step modulation in weak laser field, involving its total photoelectron energy, maximal photoelectron intensity, and spectroscopic bandwidth. Our results show that the tota...
Using the methods of Auger electron and photoelectron spectroscopy light absorption spectroscopy, composition, densities state electrons in valence band, parameters energy bands Ge (111) implanted with Na + ions an E 0 =0.5 keV at a dose D sat =6· 10 16 cm -2 thin layer NaGe 2 obtained by annealing ion-implanted Ge. It is shown that narrow n-type band (~ 0.2 eV) appears spectrum after ion impla...
The electronic structure of epichlorohydrin is investigated in the whole valence region by a combined experimental and theoretical study. The issue of controversial assignments of the molecular electronic structure is here addressed. Photoelectron spectra (PES) and Threshold Photoelectron spectra (TPES) of room temperature molecules in the gas phase are recorded. Geometries and energies of the ...
