Theoretical design of a liquid-core photonic crystal fiber for supercontinuum generation.

Optics express

Zhang R, Teipel J, Giessen H.
PMID: 19516862
Opt Express. 2006 Jul 24;14(15):6800-12. doi: 10.1364/oe.14.006800.

We have numerically studied a hollow-core photonic crystal fiber, with its core filled with highly nonlinear liquids such as carbon disulfide and nitrobenzene. Calculations show that the fiber has an extremely high nonlinear parameter gamma on the order of...

Time gate, optical layout, and wavelength effects on ballistic imaging.

A method to distinguish a hidden object from a perturbing environment is to use an ultrashort femtosecond pulse of light and a time-resolved detection. To separate ballistic light containing information on a hidden object from multiscattered light coming from...

Measurements of a nonlinear refractive index with a single laser pulse.

Applied optics

Hein J, Helbig M, Rentsch S.
PMID: 18250786
Appl Opt. 1997 Feb 20;36(6):1173-6. doi: 10.1364/ao.36.001173.

We demonstrate a theoretical model and the experimental proof of a new method for n(2) measurements using single pulses. The advantage of the method is fast measurement, a simple setup, and independence from small nonlinear absorptions and thermal effects....

Stimulated Raman scattering and four-wave mixing from a mixture of carbon disulfide and phenylethanol in a hollow optical fiber.

Opt Lett. 1991 Oct 01;16(19):1469-71. doi: 10.1364/ol.16.001469.

We observe, for what is to our knowledge the first time, stimulated Raman scattering and four-wave mixing in a liquid-core optical fiber filled with a mixture of carbon disulfide and phenylethanol pumped by the frequencydoubled output of a Q-switched...

Effect of water on the electrical properties of carbon nanotubes.

Journal of nanoscience and nanotechnology

Mendoza D, Santiago P.
PMID: 19205234
J Nanosci Nanotechnol. 2008 Dec;8(12):6523-7.

In this work we present the electrical characterization of carbon nanotubes synthesized by a thermal chemical deposition method, using carbon disulfide as the precursor of carbon and iron as the catalyst. We found a broad maximum in the electrical...

High-resolution electron momentum spectroscopy of valence satellites of carbon disulfide.

Huang C, Shan X, Zhang Z, Wang E, Li Z, Chen X.
PMID: 20886928
J Chem Phys. 2010 Sep 28;133(12):124303. doi: 10.1063/1.3481778.

The binding energy spectrum of carbon disulphide (CS(2)) in the energy range of 9-23 eV has been measured by a high-resolution (e,2e) spectrometer employing asymmetric noncoplanar kinematics at an impact energy of 2500 eV plus the binding energy. Taking...

PMID: 20441157
Inorg Chem. 2010 Jun 07;49(11):5120-5. doi: 10.1021/ic1002513.

Two modifications to the doubly concaved host molecules based on well-known nickel tetraazaannulene complexes have resulted in the preparation of the compounds Ni(NapTMTAA).2benzene, 1,6,8,15,17-tetramethyldinapthalene-5,9,14,18-tetraazacyclotetradecinatonickel(II), and Ni(Cl(4)TMTAA).CH(2)Cl(2), 2,3,11,12-tetrachloro-6,8,15,17-tetramethyldibenzo-5,9,14,18-tetraazacyclotetradecinatonickel(II). When crystallized with C(60) in carbon disulfide, the crystalline, well-ordered, host-guest compounds...

Soil fumigation: principles and application technology.

Journal of nematology

Lembright HW.
PMID: 19287772
J Nematol. 1990 Oct;22(4):632-44.

The principal soil fumigants and their order of discovery are carbon disulfide, chloropicrin, methyl bromide, 1,3-dichloropropene, ethylene dibromide, 1,2-dibromo-3-chloropropane, and methyl isothiocyanate. Biological activity of soil fumigants ranges from limited to broad spectrum. Fumigants diffuse through the continuous soil...

New Kerr cell for low-temperature measurements.
