Photon beams of 99 eV energy carrying orbital angular momentum (OAM) have been observed in the 2nd harmonic off-axis radiation a helical undulator at 3rd generation synchrotron light source BESSY II. For detection, OAM photon beam was superimposed with reference without OAM. The interference pattern, spiral intensity distribution, recorded plane perpendicular to propagation direction. orientation structure is related helicity radiation. Excellent agreement between measurements and...
Here the major upgrades of femtoslicing facility at BESSY II (Khan et al., 2006) are reviewed, giving a tutorial on how elliptical-polarized ultrashort soft X-ray pulses from electron storage rings generated high repetition rates. Employing 6 kHz femtosecond-laser system consisting two amplifiers that seeded by one Ti:Sa oscillator, total average flux photons 100 fs duration (FWHM) has been increased factor 120 to up 10(6) s(-1) (0.1% bandwidth)(-1) sample in range 250 1400 eV.

In this work we present the characterization of PAMAM dendrimers from generation two (G2) up to ten (G10) with a focus on G5−G10 matrix-assisted laser desorption/ionization linear mass spectrometry (MALDI−MS) and nanoelectrospray gas-phase electrophoretic mobility molecular analysis (nES−GEMMA). For first time masses high-mass G8−G10 were determined by MALDI−MS nES−GEMMA, techniques which are based different physicochemical principles. Obtained experimental data allows determination (up 580...
ABSTRACT Fuel oxygenates such as methyl and ethyl tert- butyl ether (MTBE ETBE, respectively) are degraded only by a limited number of bacterial strains. The aerobic pathway is generally thought to run via alcohol (TBA) 2-hydroxyisobutyrate (2-HIBA), whereas further steps unclear. We have now demonstrated for the newly isolated β-proteobacterial strains L108 L10, well closely related strain CIP I-2052, that 2-HIBA was cobalamin-dependent enzymatic step. In these strains, growth on substrates...

All share the ability to grow on -butanol, an intermediate of MTBE degradation. Cells are strictly aerobic, motile by polar flagellum exhibit strong pili formation. Poly β -hydroxybutyrate (PHB) granules formed. The DNA G+C content is 69–70.5 mol% main ubiquinone Q-8. major cellular fatty acids 16 : 1 cis -9 0 only hydroxy acid...

Microbial degradation of contaminants in the subsurface requires availability nutrients; this is impacted by porous media heterogeneity and degree transverse mixing. Two types microfluidic pore structures etched into silicon wafers (i.e., micromodels), (i) a homogeneous distribution cylindrical posts (ii) aggregates large small posts, were used to evaluate impact on growth pure culture (Delftia acidovorans) that degrades (R)-2-(2,4-dichlorophenoxy)propionate (R-2,4-DP).

Paramagnetic transition metals play a crucial role as cofactors in various cellular catalytic processes. However, their high concentrations reactive oxidation states can induce oxidative stress, resulting cell dysfunction or death.

Abstract In biotechnological processes, fundamental performances of microorganisms are used. The economy these processes is essentially determined by the efficiency, velocity (productivity) and quality products. Therefore it a permanent task challenge for basic research to seek out measures improving actually attained parameters. auxiliary substrate concept supplics an approach. It based on fact that chemo‐organo‐heterotrophic substrates differ in carbon: energy ratio, thus, growth yield...
The energy-based classification of heterotrophic substrates requires biochemical evaluation because some can be assimilated by a variety different metabolic pathways. By using the Y ATP-concept it was shown that depends on yield ATP and reducing equivalents already generated way to precursor (phosphoglycerate). With carbon-excess part total substrate consumed must oxidized completion merely for energy production, whereas with energy-excess more is provided route than needed assimilation...
The utilization of the fuel oxygenate methyl tert-butyl ether (MTBE) and related compounds by microorganisms was investigated in a mainly theoretical study based on Y(ATP) concept. Experiments were conducted to derive realistic maintenance coefficients K(s) values needed calculate substrate fluxes available for biomass production.
