The catalytic decomposition of ozone (200-1600 ppm) to molecular oxygen was investigated over activated carbons in the form of woven fibre fabrics (ACF) or granules (ACG) at room temperature. The dynamics of carbon activity was characterised by two distinc ...
C60 fullerene reacted with phosphorus at high temperatures to graphitic materials with strongly differing properties. Several spectroscopic investigations as Raman, ESR, XPS and 31P-NMR as well as TEM and ESEM have shown that the structural order of the mo ...
With the aim of improving the rate capability and the safety of nanocrystalline Li4Ti5O12-based high power lithium ion batteries, two high boiling point nitrile-based electrolytes namely, 3-ethoxypropionitrile (CH3CH2OCH2CH2CN, EPN)/1 M LiTFSI and 3-(2,2,2 ...
Stress-induced changes in the imprint and switching behavior of (111)-oriented Pb(Zr,Ti)O-3 (PZT)-based capacitors have been studied using piezoresponse force microscopy. Visualization of polarization distribution and d(33)-loop measurements in individual ...
We present an analysis of the hemispherical-directional reflectance factor (HDRF) of snow, using 16 seasonal datasets of the spectral range from 400 to 2,500 nm. The data was measured under clear sky conditions in Davos Dorf (Grisons, Switzerland, 1,560 m ...
A SOFC, with a solid electrolyte layer and at least one anode layer constituting a stratified structure. The anode layer incorporates a twice substituted lanthanide chromite, substituted by Sr on A sites and by Ni or Cu on B sites. The stratified structure ...
A new generation of high power Li-ion batteries that avoid carbon as anodic material replacing it with the spinel Li4Ti5O12 has been studied in this work. For these new Li-ion cells new electrolyte compositions can be considered. The main work of this thes ...
Diamond films with different levels of doping have been the subject of applications and fundamental research in electrochemistry, opening up a new branch known as the electrochemistry of diamond. The electrochemical properties of diamond mostly depend on t ...
The present paper investigates the complete regulation strategy for a large double-fed asynchronous motor-generator equipped with a 3-level VSI cascade for applications mainly in the field of pumped storage plant. For the present application, the specific ...
A review. Although the synthesis of beta -lactams by means of tethered Ugi reactions was known since the early 1960s, the 1995 report from Ugi's group could be regarded as a turning point in the development of novel multicomponent reactions (MCRs) for hete ...
