Electronic structure of A- and B-site doped lanthanum manganites: a combined X-ray spectroscopic study.

The electronic properties of a series of colossal magnetoresistance (CMR) compounds, namely LaMnO3, La(1-x)Ba(x)(MnO3 (0.2 < or = x < or = 0.55), La(0.

Unifit 2002--universal analysis software for photoelectron spectra.

The current level of development of the spectra analysis software Unifit for Windows is presented and evaluated by checking with test spectra. The program is characterized and the correctness of the numerical routines is demonstrated for the particular cases of the Shirley type background model and the Gaussian-Lorentzian product model functions. Different approaches to an optimum fit result are suggested.

Amperometric carbohydrate detection in flow systems by means of a bismuth modified platinum electrode.

Bismuth modified platinum electrodes are used for constant-potential amperometric determination of carbohydrates in flow systems. The monitored response is stable and reproducible over more than two days. An attempt is made to gain more detailed information about the characteristics of the modified layer by electrochemical methods and X-ray photoelectron spectroscopy.

CCA paper: a new two-dimensional cyanuric chloride-activated matrix for universal application in molecular biology.

A novel two-dimensional cyanuric chloride-activated (CCA) paper has been developed. It is composed of a cellulosic base, covalently bound cyanuric chloride, and microprecipitated complex cyanuric chloride-sodium chloride crystals on its surface. CCA paper covalently binds nucleic acids and proteins.
