Topographical characterization and surface force spectroscopy of the photochemical lignin model compound
(Elsevier, Amsterdam, 2001)
By combining the results from atomic force microscopy (AFM) and environmental scanning electron microscopy (ESEM), herein we investigate properties of photochemical lignin model compounds. We provide evidence that photochemical ...
Comparative assessment of cardiac activity and DNA damage in haemocytes of the Mediterranean mussel Mytilus galloprovincialis in exposure to tributyltin chloride
(Elsevier Science Bv, Amsterdam, 2016)
This study gives an insight in sensitivity of heart rate (Hr) of Mytilus galloprovincialis as a physiological biomarker. Impact of tributyltin chloride (TBT-Cl) on Hr was studied in parallel with evaluation of mutagenic, ...
Activity and stability of soluble and immobilized alpha-glucosidase from baker's yeast in cosolvent systems
(Taylor & Francis Ltd, Abingdon, 2006)
The activity of alpha-glucosidase from baker's yeast was determined in various concentrations of dioxan, tetrahydrofuran, tert-butanol, dimethylformamide, methanol and dimethylsulfoxide (DMSO). Higher activities were ...
Self-assembly of Mo6S (8) clusters on the Au(111) surface
(Springer, New York, 2007)
The preferred adsorption sites and the propensity for a self-organised growth of the molybdenum sulfide cluster Mo6S8 on the Au(111) surface are investigated by density-functional band-structure calculations with ...
Relevance of the capacity of phosphorylated fructose to scavenge the hydroxyl radical
(Elsevier Sci Ltd, Oxford, 2009)
The hydroxyl radical ((OH)-O-center dot) has detrimental biological activity due to its very high reactivity. Our experiments were designed to determine the effects of equimolar concentrations of glucose, fructose and ...
Far infrared reflectance of sintered Zn2TiO4
(Springer, New York, 2008)
Zinc-titanate ceramics were obtained by initial mechanical activation in a high-energy planetary mill for 15 min followed by sintering at temperatures 900-1100 degrees C for 2 h. Room temperature far infrared reflectivity ...
Electrophysiological and spectral properties of second-order retinal neurons in the eel
(Elsevier Science Inc, New York, 1998)
Several classes of second-order neurons have been electrophysiologically explored in immature European eels (Anguilla anguilla) from two distant and ecologically different localities tin Russia and Yugoslavia). The majority ...
Spectroscopic studies of SnO2 doped with Cr, Co or Nb
(Trans Tech Publications Ltd, 2003)
SnO2 ceramics doped with different amounts of Co, Cr or Nb were investigated using visible and infrared spectroscopy at room temperature. Based on the observed d-d transitions the valence states of incorporated dopants ...
Capacity of cerebrospinal fluid to transform hydrogen peroxide-relation to neurodegenerative changes in ALS
(Taylor & Francis Ltd, Abingdon, 2006)
Fenton reaction produces hydrogen radical (center dot H) in chemical and biological systems
(Taylor & Francis Ltd, Abingdon, 2006)
