Creation and characterization of free-standing cryogenic targets for laser-driven ion acceleration.

The Review of scientific instruments

Tebartz A, Bedacht S, Hesse M, Astbury S, Clarke R, Ortner A, Schaumann G, Wagner F, Neely D, Roth M.
PMID: 28964232
Rev Sci Instrum. 2017 Sep;88(9):093512. doi: 10.1063/1.5001487.

A technique for the creation of free-standing cryogenic targets for laser-driven ion acceleration is presented, which allows us to create solid state targets consisting of initially gaseous materials. In particular, the use of deuterium and the methods for its...

Chlorosomes of green sulfur bacteria: Pigment composition and energy transfer.

Photosynthesis research

van Noort PI, Francke C, Schoumans N, Otte SC, Aartsma TJ, Amesz J.
PMID: 24310026
Photosynth Res. 1994 Jul;41(1):193-203. doi: 10.1007/BF02184160.

The pigment composition and energy transfer pathways in isolated chlorosomes ofChlorobium phaeovibrioides andChlorobium vibrioforme were studied by means of high performance liquid chromatography (HPLC) and picosecond absorbance difference spectroscopy. Analysis of pigment extracts of the chlorosomes revealed that they...

Influence of Organic Chemicals on Water Molecule Bridges in Soil Organic Matter of a Sapric Histosol.

The journal of physical chemistry. A

Ondruch P, Kucerik J, Steinmetz Z, Schaumann GE.
PMID: 28252302
J Phys Chem A. 2017 Mar 30;121(12):2367-2376. doi: 10.1021/acs.jpca.6b10207. Epub 2017 Mar 16.

Water molecules in soil organic matter (SOM) can form clusters bridging neighboring molecular segments (water molecule bridges, WaMBs). WaMBs are hypothesized to enhance the physical entrapment of organic chemicals and to control the rigidity of the SOM supramolecular structure....

Pentagonal dodecahedranes: polyfunctionalization and MS fragmentation.

The Journal of organic chemistry

Landenberger P, Scheumann K, Keller M, Hunkler D, Fritz H, Wörth J, Knothe L, Prinzbach H.
PMID: 11511248
J Org Chem. 2001 Aug 24;66(17):5744-58. doi: 10.1021/jo010170+.

With the use of four- to eight-fold functionalized dodecahedranes (1-3), opportunities to arrive at highly strained dodecahedranes with two to four pairs of vicinal, eclipsed bromine substituents through front-side substitution and addition reactions have been explored. In standard processes,...

Chloride selective calix[4]arene optical sensor combining urea functionality with pyrene excimer transduction.

Journal of the American Chemical Society

Schazmann B, Alhashimy N, Diamond D.
PMID: 16802827
J Am Chem Soc. 2006 Jul 05;128(26):8607-14. doi: 10.1021/ja061917m.

A neutral 2-site chloride selective compound has been developed (3), based on a 1,3-alternate tetrasubstituted calix[4]arene providing a preorganized supramolecular scaffold. The resultant supramolecular cavity is among the first to combine urea functional groups bridged with single methylene spacers...

Discrimination of Enterobacteriaceae and Non-fermenting Gram Negative Bacilli by MALDI-TOF Mass Spectrometry.

The open microbiology journal

Schaumann R, Knoop N, Genzel GH, Losensky K, Rosenkranz C, Stîngu CS, Schellenberger W, Rodloff AC, Eschrich K.
PMID: 23919091

Intense lasers interacting with dense targets accelerate relativistic electron beams, which transport part of the laser energy into the target depth. However, the overall laser-to-target energy coupling efficiency is impaired by the large divergence of the electron beam, intrinsic...

Gamification of Crowd-Driven Environment Design.

IEEE computer graphics and applications
