Synthesis of p-Cyano(2,3-naphthalocyaninato)iron(III) and comparison to u-Cyano(phthalocyaninato)iron(III)
Potassium dicyano(2,3-naphthalocyaninato)ferrate(III), K[2,3-NcFe(CN)(2)], reacts in water with elimination of KCN to form p-cyano(2,3-naphthalocyaninato)iron(III)[,2 ,3-NcFe(CN)In (4a). D ichloro(2,3-naphthalocyaninato) ...
Synthesis and characterization of Nitrido(tetra-tert-butylphthalocyaninato)rhenium(V) and Nitrido(phthalocyaninato)rhenium(V)
4-tert-Butylphthalodinitrile (1) reacts with ammonium perrhenate, NH4Re04, to yield nitrido(tetra-tert-butylphthalocyaninato) rhenium(V),( tBu)4PcReN (2) , which is characterized by IR, UV/Vis, CV, MS, "H and I3C NMR, and ...
Non-adiabatic effects in the dissociative adsorption of O2 on aluminum (111) surfaces
The low sticking probability for thermal oxygen molecules at aluminum(111) has recently been related to spin selection rules, which hinder transitions from the initial oxygen gas-phase triplet state to the singlet state ...
Identifizierung kleiner nicht-kodierender RNA-Moleküle und molekularbiologische Analysen über das RNA-Chaperon Hfq in Acinetobacter baylyi ADP1
Hfq is a conserved bacterial RNA-chaperone. In gamma-proteobacteria Hfq shows a great variation in its C-terminus. Extremely large Hfq proteins (200 amino acids) are found within the gamma-proteobacterial family Moraxellaceae. ...
Magnetische Anisotropie in GaMnAs
GaMnAs belongs to the group of dilute magnetic semiconductors (DMS). It shows a pronounced magnetic anisotropy (MA) and striking anisotropic magneto-resistance (AMR) effects. The magnetic properties of DMS can be controlled ...
Optimization of red fluorescent marker proteins guided by evaluation of structure-function relations
Red fluorescent proteins (RFPs) attract particular attention from both scientific and practical points of view. They have a great potential to be used as in vivo markers in multicolour labelling and FRET-based applications. ...
Verkapselung von hydrophilen Agenzien mittels inverser Miniemulsionstechnik und deren kontrollierte Freisetzung
The aim of this work was to highlight the broad possibility in preparing polyurea and polyurethane nanocapsules for the use in various applications. Depending on the choice of the monomer and surfactants, finely tuned shell ...
Physical properties of novel polypropylenes
High molecular polypropylene (MW ~ 1,100,000 g/mol) was added to a matrix of polypropylene with an average molecular weight (MW ~ 250,000 g/mol). By blending both materials we tried to combine the respective advantages ...
Characterization of LINA, a new RING-Finger protein with axon growth promoting activity
Axons in the adult CNS fail to regenerate after injury, while axons in the PNS can regrow and succeed in reinnervating their target. This difference results from the non-permissive growth environment in the CNS. Another ...
Potenzsummen, Bernoulli-Zahlen und Eulersche Summenformel
This is a didactical paper, concerning sums of powers, Bernoulli-numbers and the Euler-sum-fomula. The appendix includes a Perl-program for calculating Bernoulli-numbers and the explicit values of the first 80 Bernoulli-numbers.
