Synthesis of thiol-derivatized europium porphyrinic triple-decker sandwich complexes for multibit molecular information storage.

The Journal of organic chemistry

Li J, Gryko D, Dabke RB, Diers JR, Bocian DF, Kuhr WG, Lindsey JS.
PMID: 11076594
J Org Chem. 2000 Nov 03;65(22):7379-90. doi: 10.1021/jo000490d.

The storage of multiple bits of information at the molecular level requires molecules with a large number of distinct oxidation states. Lanthanide triple-decker sandwich molecules employing porphyrins and phthalocyanines afford four cationic states and are very attractive for molecular...

Heat conduction in one-dimensional nonintegrable systems.

Physical review. E, Statistical physics, plasmas, fluids, and related interdisciplinary topics

Hu B, Li B, Zhao H.
PMID: 11088161
Phys Rev E Stat Phys Plasmas Fluids Relat Interdiscip Topics. 2000 Apr;61(4):3828-31. doi: 10.1103/physreve.61.3828.

Two classes of one-dimensional nonintegrable systems represented by the Fermi-Pasta-Ulam (FPU) model and the discrete straight phi(4) model are studied to seek a generic mechanism of energy transport on a microscopic level sustaining macroscopic behaviors. The results enable us...

Measurement of atmospheric hydrogen peroxide and hydroxymethyl hydroperoxide with a diffusion scrubber and light emitting diode-liquid core waveguide-based fluorometry.

Analytical chemistry

Li J, Dasgupta PK.
PMID: 11080885
Anal Chem. 2000 Nov 01;72(21):5338-47. doi: 10.1021/ac000611+.

We describe a new automated instrument for measuring gas- and aqueous-phase H2O2. The chemistry relies on the hematin-catalyzed oxidation of nonfluorescent thiamine to fluorescent thiochrome by H2O2; this reaction is 25-fold more selective for hydrogen peroxide than its nearest...

The Perturbation between the G(1)Pi(g) and 2(1)Delta(g) States of (7)Li(2).

Journal of molecular spectroscopy

Shang J, Qi J, Li L, Lyyra AM.
PMID: 10986137
J Mol Spectrosc. 2000 Oct;203(2):255-263. doi: 10.1006/jmsp.2000.8188.

We have observed the rotational levels in the v = 2, 3, 5, 6, 7, and 8 vibrational manifolds of the 2(1)Delta(g) state of (7)Li(2) via the A(1)Sigma(+)(u) intermediate levels by DeltaLambda = 2 transitions. This violation of the...

The 4(3)Pi(g) State of Na(2): Vibrational Numbering and Hyperfine Structure.

Journal of molecular spectroscopy

Lazarov G, Lyyra AM, Li L, Huennekens J.
PMID: 10409455
J Mol Spectrosc. 1999 Aug;196(2):259-264. doi: 10.1006/jmsp.1999.7879.

The Na(2) 4(3)Pi(g) state has been studied by continuous-wave (cw) perturbation-facilitated optical-optical double resonance (PFOODR) fluorescence excitation and resolved fluorescence spectroscopy. The absolute vibrational numbering was determined by resolved fluorescence to the a(3)Sigma(+)(u) state. The OODR excitation lines of...

Structural analysis of polymer end groups by electrospray ionization high-energy collision-induced dissociation tandem mass spectrometry.

Analytical chemistry

Yalcin T, Gabryelski W, Li L.
PMID: 10959972
Anal Chem. 2000 Aug 15;72(16):3847-52. doi: 10.1021/ac000245u.

Chemical structures of polymer end groups play an important role in determining the functional properties of a polymeric system. We present a mass spectrometric method for determining end group structures. Polymeric ions are produced by electrospray ionization (ESI), and...

Electro-Viscous Effects on Liquid Flow in Microchannels.

Journal of colloid and interface science

Ren L, Li D, Qu W.
PMID: 11112301
J Colloid Interface Sci. 2001 Jan 01;233(1):12-22. doi: 10.1006/jcis.2000.7262.

The presence of the electrical double layer near a solid-liquid interface results in the electro-viscous effect on pressure-driven liquid flow through microchannels. The objective of this paper is to examine the magnitude of the additional flow resistance caused by...

Direct calculation of light-induced structural change and diffusive motion in glassy As2Se3.

Physical review letters

Li J, Drabold DA.
PMID: 10991233
Phys Rev Lett. 2000 Sep 25;85(13):2785-8. doi: 10.1103/PhysRevLett.85.2785.

Photostructural change of glassy As2Se3 was simulated on an experimentally credible model with excited electronic dynamics within first-principles molecular dynamics. Bond breaking and bond switching reactions account for local changes around defect sites at the short time phase of...

The incidence of oscillatory behavior in the continuous fermentation of zymomonas mobilis .

Biotechnol Prog. 1999 Jul;15(4):667-80. doi: 10.1021/bp990070d.

The incidence of oscillatory behavior in the continuous culture of Zymomonas mobilis has been examined using a combination of experimental investigations and a predictive model. The tendency to oscillatory behavior was assessed by perturbing the feed substrate concentration and...
