J Chem Ecol. 1995 Jun;21(6):833-47. doi: 10.1007/BF02033464.

Noninhibitory levels of glucose-C [≤ 72 µg carbon (C)/g soil] increased the inhibitory activity ofp-coumaric acid on morning-glory seedling biomass accumulation in Cecil Bt-horizon soil. The amount ofp-coumaric acid required for a given level of inhibition of shoot and...

Phenolic acid content of soils from wheat-no till, wheat-conventional till, and fallow-conventional till soybean cropping systems.

PMID: 24259167
J Chem Ecol. 1991 Jun;17(6):1045-68. doi: 10.1007/BF01402933.

Soil core (0-2.5 and/or 0-10 cm) samples were taken from wheat no till, wheat-conventional till, and fallow-conventional till soybean cropping systems from July to October of 1989 and extracted with water in an autoclave. The soil extracts were analyzed...

Domino Tunneling.

Journal of the American Chemical Society

Schreiner PR, Wagner JP, Reisenauer HP, Gerbig D, Ley D, Sarka J, Császár AG, Vaughn A, Allen WD.
PMID: 26027801
J Am Chem Soc. 2015 Jun 24;137(24):7828-34. doi: 10.1021/jacs.5b03322. Epub 2015 Jun 15.

Matrix-isolation experiments near 3 K and state-of-the-art quantum chemical computations demonstrate that oxalic acid [1, (COOH)2] exhibits a sequential quantum mechanical tunneling phenomenon not previously observed. Intensities of numerous infrared (IR) bands were used to monitor the temporal evolution...

Pre-Anthesis Reserve Utilization for Protein and Carbohydrate Synthesis in Grains of Wheat.

Plant physiology

Gebbing T, Schnyder H.
PMID: 10557235
Plant Physiol. 1999 Nov;121(3):871-878. doi: 10.1104/pp.121.3.871.

We assessed the contribution of pre-anthesis reserve C to protein and carbohydrate deposition in grains of wheat (Triticum aestivum L.) using a new approach comprised of steady-state (13)C/(12)C labeling and separation of the protein and carbohydrate fractions of mature...

Aligned carbon nanotube films: production and optical and electronic properties.

Science (New York, N.Y.)

Deheer WA, Bacsa WS, Châtelain A, Gerfin T, Humphrey-Baker R, Forro L, Ugarte D.
PMID: 17792177
Science. 1995 May 12;268(5212):845-7. doi: 10.1126/science.268.5212.845.

Carbon nanotube material can now be produced in macroscopic quantities. However, the raw material has a disordered structure, which restricts investigations of both the properties and applications of the nanotubes. A method has been developed to produce thin films...

Near-infrared holography by two-photon photochemistry.

Optics letters

Gerbig V, Grygier RK, Burland DM, Sincerbox G.
PMID: 19718129
Opt Lett. 1983 Jul 01;8(7):404-6. doi: 10.1364/ol.8.000404.

The applicability of the technique of two-photon four-level photochemistry for the production of near-IR holograms is critically evaluated. Although the current best system (biacetyl in a polycyanoacrylate matrix) has low recording sensitivity, several applications of the material have been...

Photoionization of three isomers of the C9H7 radical.

The journal of physical chemistry. A

Hemberger P, Steinbauer M, Schneider M, Fischer I, Johnson M, Bodi A, Gerber T.

J Phys Chem A. 2010 Apr 15;114(14):4698-703. doi: 10.1021/jp9068569.

Three resonance-stabilized radicals, 1-indenyl (Ind), 1-phenylpropargyl (1PPR), and 3-phenylpropargyl (3PPR), all isomers of the composition C(9)H(7), were generated by jet flash pyrolysis. Their photoionization was examined by VUV synchrotron radiation. The mass spectra show a clean and efficient radical...

Within the archaea, the thermoacidophilic crenarchaeote Sulfolobus solfataricus has become an important model organism for physiology and biochemistry, comparative and functional genomics, as well as, more recently also for systems biology approaches. Within the Sulfolobus Systems Biology ("SulfoSYS")-project the...
