Evidence for the presence of two conformations of the heme a 3-CuB pocket of cytochrome caa 3 from Thermus thermophilus
(2011)Resonance Raman (RR) and "light" minus "dark" Fourier transform infrared (FTIR) difference spectra are reported for the CO-bound caa3 oxidase from Thermus thermophilus. Two Fe-CO stretching modes at 518 and 507 cm-1, the ...

Inhomogeneities and Effective Mass in Doped Mg2Si
(2016)Magnesium silicide (Mg2Si)-based materials are promising candidates as thermoelectric components for mid-temperature range (500–900 K) energy conversion. Many different approaches for determining the parabolicity of the ...

Observation of ligand transfer in ba 3 oxidase from thermus thermophilus: Simultaneous FTIR detection of photolabile heme a 3 2+-CN and transient CuB 2+-CN complexes
(2012)FTIR and light-minus-dark FTIR spectroscopy have been employed to investigate the reaction of oxidized and fully reduced ba3 oxidase with cyanide. The characterization of the structures of the bound CN- in the binuclear ...

Pine needle–derived biochar adsorbents for removal of Sm(III) and competitive toxic metals from model aqueous matrices
(Elsevier, 2023)Pine needle–derived biochars have been prepared and investigated as adsorbent materials for the removal of trivalent samarium (Sm(III)) from aqueous systems. The biochars, which were previously oxidized and magnetized), ...

Thermoelectric properties of Mg2Si coatings deposited by pack cementation assisted process on heavily doped Si substrates
(2014)This work presents a study of structural and thermoelectric properties of Mg2Si coatings deposited on heavily doped p- and n-type Si substrates, at 650 C. The as-grown layers were smooth and uniform in thickness without ...

Time-resolved step-scan Fourier transform infrared investigation of heme-copper oxidases: Implications for O2 input and H 2O/H+ output channels
(2004)We have applied FTIR and time-resolved step-scan Fourier transform infrared (TRS2-FTIR) spectroscopy to investigate the dynamics of the heme-CuB binuclear center and the protein dynamics of mammalian aa3, Pseudomonas ...
