      Aldoxime dehydratase: Probing the heme environment involved in the synthesis of the carbon-nitrogen triple bond 

      Pinakoulaki, Eftychia; Koutsoupakis, Constantinos; Sawai, H.; Pavlou, A.; Kato, Y.; Asano, Y.; Aono, S. (2011)
      Fourier transform infrared (FTIR) spectra, "light" minus "dark" difference FTIR spectra, and time-resolved step-scan (TRS 2) FTIR spectra are reported for carbonmonoxy aldoxime dehydratase. Two C-O modes of heme at 1945 ...

      Fluctuations in biological and bioinspired electron-transfer reactions 

      Skourtis, Spiros S.; Waldeck, D. H.; Beratan, David N. (2010)
      Central to theories of electron transfer (ET) is the idea that nuclear motion generates a transition state that enables electron flow to proceed, but nuclear motion also induces fluctuations in the donor-acceptor (DA) ...

      Pentanuclear complexes with unusual structural topologies from the initial use of two aliphatic amino-alcohol ligands in Fe chemistry 

      Kizas, Christos M.; Manos, Manolis J.; Nastopoulos, Vassilios; Boudalis, Athanassios K.; Sanakis, Yiannis; Tasiopoulos, Anastasios J. (2012)
      Five novel pentanuclear Fe 3+ clusters with the aliphatic amino-alcohol ligands 3-amino-1-propanol (Hap) and 2-(hydroxymethyl)piperidine (Hhmpip) [Fe 5(μ 3-Ο) 2(L) 4(O 2CR) 7] [L = ap -, R = Ph (1)

      Structure anisotropy in MHD turbulence subjected to mean shear and frame rotation 

      Kassinos, Stavros C.; Wray, A. (Affiliation: Dept. of Mechanical and Manufacturing Engineering, University of Cyprus, Nicosia, CyprusAffiliation: Department of Mechanical Engineering, Stanford University, Stanford, CA 94305, United StatesAffiliation: Center for Turbulence Research, NASA Ames Research Center, United StatesCorrespondence Address: Kassinos, S.C.Dept. of Mechanical and Manufacturing Engineering, University of Cyprus, Nicosia, Cyprusemail: kassinos@ucy.ac.cy, 2005)
      We consider homogeneous turbulence in a conducting fluid that is exposed to a uniform external magnetic field while being sheared in fixed and rotating frames. We take both the frame-rotation axis and the applied magnetic ...

      Ultrafast hole carrier relaxation dynamics in p-type CuO nanowires 

      Othonos, Andreas S.; Zervos, Matthew (2011)
      Ultrafast hole carrier relaxation dynamics in CuO nanowires have been investigated using transient absorption spectroscopy. Following femtosecond pulse excitation in a non-collinear pump-probe configuration, a combination ...

      Ultrafast time-resolved spectroscopy of ZnSe nanowires: Carrier dynamics of defect-related states 

      Othonos, Andreas S.; Lioudakis, Emmanouil E.; Tsokkou, Demetra; Philipose, U.; Ruda, H. E. (2009)
      In recent years, ZnSe nanowires have been widely investigated for their potential applications in optoelectronics. A typical room temperature photoluminescence spectrum of ZnSe nanowires grown by vapor-liquid-solid growth ...
