Altering the emission behavior with the turn of a thiophene ring: The photophysics of condensed ring systems of alternating benzenes and thiophenes
No full textSix aromatic compounds with embedded thiophenes differing in the number of rings (2-5) and thiophene orientation along the long axis of the molecule (syn, anti) were investigated. Photophysical properties, steady-state absorption, fluorescence, phosphorescence, lifetimes, quantum yields, and a comprehensive time-resolved spectroscopic analysis (femtosecond and nanosecond transient absorption spectroscopy) have been studied as a function of molecular structure. © 2006 American Chemical Society.Aaron JJ, 2002, J FLUORESC, V12, P231, DOI 10.1023-A:1016869002735; Abdel-Shafi AA, 2005, J PHOTOCH PHOTOBIO A, V172, P170, DOI 10.1016-j.photochem.2004.12.006; AGGARWAL N, 1979, ORG PREP PROCED INT, V11, P247; Becker RS, 1996, J PHYS CHEM-US, V100, P18683, DOI 10.1021-jp960852e; BEIMLING P, 1986, CHEM BER-RECL, V119, P3198, DOI 10.1002-cber.19861191025; Berlman I.

End-capping of conjugated thiophene-benzene aromatic systems
No full textThe synthesis of end-capped thieno[3,2-f:4,5-f′]bis[1]benzothiophene was achieved from thiophene and 2,5-thiophenedicarboxaldehyde. Specifically, hexyl and dodecyl end-capping groups conferred reversible redox behavior as evidenced by cyclic voltammetry with oxidation potentials of 0.73 V versus Fc-Fc+ couple. An extensive spectrophotometric analysis is reported. © 2010 Elsevier Ltd.

Gustav Ritter von Wex, sein Leben und Werk
No full textSummary: The regulation works of Danube river along Vienna city around 1870 are described as a monumental European project of the 19th century. The publications of the project head Gustav von Wex (1811-1892) are thereby reviewed, given that he therein considered the historical bases, the imperial decision, the project outline and the advances of the works. In addition, the scientific works of von Wex are also described and put into a historical context. Finally, the biography of von Wex is presented along with the problems in searching successfully his portrait. This historical work is intended to add to the early developments in river engineering of Europ
Efficacy of Wex-cide 128 disinfectant against multiple prion strains
No full textPrion diseases are transmissible, fatal neurologic diseases that include Creutzfeldt-Jakob Disease (CJD) in humans, chronic wasting disease (CWD) in cervids, bovine spongiform encephalopathy (BSE) in cattle and scrapie in sheep. Prions are extremely difficult to inactivate and established methods to reduce prion infectivity are often dangerous, caustic, expensive, or impractical. Identifying viable and safe methods for treating prion contaminated materials is important for hospitals, research facilities, biologists, hunters, and meat-processors. For three decades, some prion researchers have used a phenolic product called Environ LpH (eLpH) to inactivate prions. ELpH has been discontinued, but a similar product, Wex-cide 128, containing the similar phenolic chemicals as eLpH is now available. In the current study, we directly compared the anti-prion efficacy of eLpH and Wex-cide 128 against prions from four different species (hamster 263K, cervid CWD, mouse 22L and human CJD). Decontamination was performed on either prion infected brain homogenates or prion contaminated steel wires and mouse bioassay was used to quantify the remaining prion infectivity. Our data show that both eLpH and Wex-cide 128 removed 4.0–5.5 logs of prion infectivity from 22L, CWD and 263K prion homogenates, but only about 1.25–1.50 logs of prion infectivity from human sporadic CJD. Wex-cide 128 is a viable substitute for inactivation of most prions from most species, but the resistance of CJD to phenolic inactivation is a concern and emphasizes the fact that inactivation methods should be confirmed for each target prion strain

WEX continues to eye expansion : a decade after IPO, technology is integral to global growth
No full textWEX, the leading fleet card provider in the United States has achieved a 10% to 15% annual growth rate since it became publicly traded in 2005. WEX President and CEO Melissa Smith believes that growth rate can be sustained by accelerated growth, making targeted investments, and driving scale. The company has become more global and has acquisitioned travel, corporate and health payments to its business portfolio, will help the company achieve this growth. WEX has a customer base in nine European countries and physical offices in five countries. The company purchased Evolution1, a cloud-based technology and health care payment service, and Exxon Mobil’s European commercial fuel card program, which should give the company a solid opportunity to expand not only in Europe but in Asia Pacific market as well
