We demonstrate the possibility of using x-ray photoemission spectroscopy (XPS) to distinguish between the chemical properties of the neuron membrane and of the cytoplasm in brain cells. This was possible by analysing cells de-capped by using a newly develo ...
The structural, electronic, and dynamic properties of the organolithium compd. C2H2Li2 were studied via ab initio mol. dynamics simulations based on the Car-Parrinello method. Dynamic simulated annealing techniques applied to search for the low-energy conf ...
A compound, in metal-free or metal complex form of formula (1) to (3) in which R is hydrogen or C1-30 alkyl; X is hydrogen, halogen (preferably Cl or Br) or C1-30 alkyl. ...

The calculation or voltages induced by indirect lightning on multiconductor lines has been the subject of several studies. The reported conclusions are not always in agreement with each other. In this paper, using a modeling procedure presented in a previo ...
The calculation of voltages induced by indirect lightning on multiconductor overhead power lines has been the subject of several studies. The reported conclusions are not always in agreement with each other. In this paper, using a modeling procedure presen ...
Scanning near-field optical microscopy (SNOM) is an optical microscopy whose resolution is not bound to the diffraction limit. It provides chemical information based upon spectral, polarization and/or fluorescence contrast images. Details as small as 20 nm ...
We tested a new soft-x-ray transmission spectromiscropy technique on the Aladdin storage ring at the Wisconsin Synchrotron Radiation Center. Transmitted x rays were converted with a photocathode into photoelectrons, which were subsequently electron-optical ...
The concept of photoinduced electron transfer has been explored for the development of polymeric transducers for optical ion-detection devices. For this purpose, a series of N-(9-anthrylmethyl)monoaza-18-crown-6 substituted poly(methacrylate)s were prepare ...
An approximation to an implicit infiltration formula presented earlier in this series is developed. At worst, the relative error of the approximation is always less than 1%, and it is much better than that for most cases. The approximation becomes more acc ...
The elemental compn. of microorganisms varies widely with respect to the N, S, P, and ash content as well as many trace elements depending on microorganism and growth conditions. As a consequence, the mass of 1 C-mol of biomass can differ considerably from ...
