Amorphous and highly nonstoichiometric titania (TiOx) thin films close to metal-like conductivity
(2014)Oxygen-deficient titanium oxide films (TiOx) have been prepared by pulsed laser deposition at room temperature. Samples in their as-deposited state have an average composition of TiO1.6, are optically absorbing and show ... -
Bimodal mesoporous titanium dioxide anatase films templated by a block polymer and an ionic liquid: influence of the porosity on the permeability
(2013)In the present paper, we report the synthesis of bimodal mesoporous anatase TiO2 films by the EISA (Evaporation-Induced Self-Assembly) method using sol-gel chemistry combining two porogen agents, a low molecular weight ... -
Blood parasites in noddies and boobies from Brazilian offshore islands : differences between species and influence of nesting habitat
(2014)Seabirds are often free from blood parasites, and a recent review suggested that phylogenetic, ecological and life-history parameters can determine the prevalence of blood parasites in seabirds. However, there is a lack ... -
Brachsysteme und Zelgengebundener Anbau in Zentral- und Ostnepal
(1973)Die sehr variablen geographischen und klimatischen Bedingungen in Nepal resultieren in einer Bandbreite agrarischer Anbaumethoden. Während in tieferen Lagen der Nassreisanbau dominiert, gibt es in größeren Höhen eine ... -
Chemie und Licht : Eine weihnachtliche Experimentalvorlesung
(2001)Dass viele chemische Reaktionen unter Lichterscheinung verlaufen, ist jedem geläufig. Chemische Reaktionen, bei denen es leuchtet, stehen mit einer groß,en Bandbreite für Demonstrationsversuche zur Verfügung: Wollen wir ... -
Chemische Triebkräfte : Von der Verbrennung zum Herzschlag
(2004)Was hat eine einfache chemische Verbrennung mit dem Herzschlag zu tun? Diese Frage soll im Rahmen einer physikalisch-chemischen Experimentalvorlesung beantwortet werden. Dabei fügen sich anscheinend weit voneinander entfernte ... -
Coherent analysis of disordered mesoporous adsorbents using small angle X-ray scattering and physisorption experiments
(2014)Characterization of mesoporous adsorbents is traditionally performed in terms of the pore size distribution with bulk methods like physisorption and mercury intrusion. But their application relies on assumptions regarding ... -
Complete experimental rovibrational eigenenergies of HCN up to 6880 cm(-1) above the ground state
(2011)The [H, C, N] molecular system is a very important model system to many fields of chemical physics and the experimental characterization of highly excited vibrational states of this molecular system is of special interest. ... -
Controlled electrochemical growth of silver microwires
(2005)The cathodic deposition of silver whiskers as microwires in the electrochemical cell Ag/AgBr/Ag has been investigated. From growth experiments observed with an optical microscope, we conclude that the growth process occurs ... -
Conversion reactions for sodium-ion batteries
(2013)Research on sodium-ion batteries has recently been rediscovered and is currently mainly focused on finding suitable electrode materials that enable cell reactions of high energy densities combined with low cost. Naturally, ... -
Coulometric titration at low temperatures-nonstoichiometric silver selenide
(2003)A modified coulometric titration technique is described for the investigation of nonstoichiometric phases at low temperatures. It allows to obtain titration curves at temperatures where the conventional coulometric titration ... -
Covalently trapping MutS on DNA to study DNA mismatch recognition and signaling
(2012)The DNA repair protein MutS forms clamp-like structures on DNA that search for and recognize base mismatches leading to ATP-transformed signaling clamps. In this study, the mobile MutS clamps were trapped on DNA in a ... -
Determination of local potentials in mixed conductors : two examples
(1995)Two basic experiments for the measurement of local (electro-)chemical potentials in crystalline mixed conductors, which are exposed to external forces, are reported, (a) The profile of the chemical potential of silver metal ... -
Diamondoid-modified DNA
(2011)We prepared novel C5-modified triphosphates and phosphoramidites with a diamondoid functionally linked to the nucleobase. Using primer extension experiments with different length templates we investigated whether the ...
