Acceleration of sub-relativistic electrons with an evanescent optical wave at a planar interface.

Optics express

Kozák M, Beck P, Deng H, McNeur J, Schönenberger N, Gaida C, Stutzki F, Gebhardt M, Limpert J, Ruehl A, Hartl I, Solgaard O, Harris JS, Byer RL, Hommelhoff P.

Opt Express. 2017 Aug 07;25(16):19195-19204. doi: 10.1364/OE.25.019195.

We report on a theoretical and experimental study of the energy transfer between an optical evanescent wave, propagating in vacuum along the planar boundary of a dielectric material, and a beam of sub-relativistic electrons. The evanescent wave is excited...

Coherent frequency division with a degenerate synchronously pumped optical parametric oscillator.

Optics letters

Wan C, Li P, Ruehl A, Hartl I.
PMID: 29489780
Opt Lett. 2018 Mar 01;43(5):1059-1062. doi: 10.1364/OL.43.001059.

Synchronously pumped optical parametric oscillators (OPOs) are important tools for frequency comb (FC) generation in the mid-IR spectral range, where few suitable laser gain materials exist. For degenerate OPOs, self-phase-locking to the pump FC has been demonstrated. Here, we...

Mechanisms of blood flow and hypoxia production in rat 9L-epigastric tumors.

Tumor microenvironment and therapy

Koch CJ, Jenkins WT, Jenkins KW, Yang XY, Shuman AL, Pickup S, Riehl CR, Paudyal R, Poptani H, Evans SM.
PMID: 25436211
Tumor Microenviron Ther. 2013 Jan;1:1-13. doi: 10.2478/tumor-2012-0001.

Classical descriptions of tumor physiology suggest two origins for tumor hypoxia; steady-state (diffusion-limited) hypoxia and cycling (perfusion-modulated) hypoxia. Both origins, primarily studied and characterized in murine models, predict relatively small, isolated foci or thin shells of hypoxic tissue interspersed...

Transarterial Embolization and Percutaneous Ethanol Injection as an Effective Bridge Therapy before Liver Transplantation for Hepatitis C-Related Hepatocellular Carcinoma.

Gastroenterology research and practice

Gastroenterol Res Pract. 2016;2016:9420274. doi: 10.1155/2016/9420274. Epub 2015 Dec 27.

Background. Transarterial chemoembolization alone or in association with radiofrequency ablation is an effective bridging strategy for patients with hepatocellular carcinoma awaiting for a liver transplant. However, cost of this therapy may limit its utilization. This study was designed to...

Electrochemical and spectroscopic characterization of the novel charge-transfer ground state in diimine complexes of ytterbocene.

Inorganic chemistry

Da Re RE, Kuehl CJ, Brown MG, Rocha RC, Bauer ED, John KD, Morris DE, Shreve AP, Sarrao JL.

The novel charge-transfer ground state found in alpha,alpha'-diimine adducts of ytterbocene (C(5)Me(5))(2)Yb(L) [L = 2,2'-bipyridine (bpy) and 1,10-phenanthroline (phen)] in which an electron is spontaneously transferred from the f(14) metal center into the lowest unoccupied (pi*) molecular orbital (LUMO)...

OH-stretch vibrational spectroscopy of hydroxymethyl hydroperoxide.

The journal of physical chemistry. A

Fry JL, Matthews J, Lane JR, Roehl CM, Sinha A, Kjaergaard HG, Wennberg PO.
PMID: 16737255
J Phys Chem A. 2006 Jun 08;110(22):7072-9. doi: 10.1021/jp0612127.

We report measurement and analysis of the photodissociation spectrum of hydroxymethyl hydroperoxide (HOCH(2)OOH) and its partially deuterated analogue, HOCD(2)OOH, in the OH-stretching region. Spectra are obtained by Fourier transform infrared spectroscopy in the 1nu(OH) and 2nu(OH) regions, and by...

The development of the optical frequency comb (a spectrum consisting of a series of evenly spaced lines) has revolutionized metrology and precision spectroscopy owing to its ability to provide a precise and direct link between microwave and optical frequencies....

Broadband phase noise suppression in a Yb-fiber frequency comb.
