We describe a method for tracking tongue, lips, and throat in X-ray films showing the side-view of the vocal tract. The technique uses specialized histogram normalization techniques and a new tracking method that is robust against occlusion, noise, and spo ...
(2,6-Dichlorophenyl)- and (2,6-dibromophenyl)trialkylsilanes undergo hydrogen/metal interconversion preferentially at the 4- rather than 3-position. However, the organometallic species generated by such a "meta metalation" are thermodynamically less stab ...
We report the formation of silicon oxide thin films obtained at room temperature by Ar+ bombardment of Si(100) wafers in partial oxygen atmosphere, The ion bombardment was done in the energy range E(b) - 100-1000 eV, with Ar partial pressure P-Ar = 1 x 10( ...
Properties of ultra-thin films are different from their single crystal counterparts due to the presence of (substrate induced) strain, different degree and type of (growth induced) disorder and different average doping (distribution of oxygen vacancies, fo ...
Using a combined experimental and theoretical approach, we address C 1s core-level shifts in amorphous carbon. Experimental results are obtained by x-ray photoelectron spectroscopy (XPS) and electron-energy-loss spectroscopy (EELS) on thin-film samples of ...
A phosphino,oxazoline P,N-bidentate ligand, 4, contg. 3,5-di-tert-butylphenyl groups was prepd. In the Heck arylation of dihydrofuran, 4 affords higher ee's than either 2 or 3, the unsubstituted and m-dimethylphenyl analogs, resp. Several Pd(0) complexes o ...
We performed feasibility tests of photoelectron emission spectromicroscopy of wet samples in the water window (285-532 eV) soft x-ray spectral region. Water was successfully confined in an ultrahigh vacuum compatible compartment with x-ray transparent side ...
Lead zirconium titanium oxide (PZT) thin films are used for their ferroelectric and piezoelectric properties. The composition of the PZT is very important for these properties, and may also be influenced by inter- diffusion with the bottom electrode, on wh ...
Aluminum oxidation states in stoichiometric or substoichiometric configuration are studied by core level photoemission spectroscopy on different substrates (SiO2, graphite). They are compared with recent results reported for the interface Si-Al-n+O. Three ...
The potentially extractable information carried by photoelectron spectromicroscopy data is analyzed. The results are used into finding practical optimization rules for different types of photoemission spectroscopy, microscopy, and spectromicroscopy experim ...
