Anion-pi interactions in active centers of superoxide dismutases
(Elsevier, 2018)
We investigated 1060 possible anion-pi interactions in a data set of 41 superoxide dismutase active centers. Our observations indicate that majority of the aromatic residues are capable to form anion-pi interactions, mainly ...
Effect of boric acid on the porosity of clay and diatomite monoliths
(Elsevier Sci Ltd, Oxford, 2016)
Porous silica ceramics were obtained at low forming pressure (40-80 MPa) and low sintering temperature (850-1300 degrees C) for 4 h in air. Boric acid was used as a low-cost additive, in the amount of 2 wt%. Relatively ...
Crystallographic and ab Initio Study of Pyridine Stacking Interactions. Local Nature of Hydrogen Bond Effect in Stacking Interactions
(American Chemical Society (ACS), 2012)
Stacking interactions between pyridine molecules and the influence of simultaneous hydrogen bonds were studied by analyzing data in the Cambridge Structural Database (CSD) and by ab initio calculations. The results show ...
C-H/O Interactions of Aromatic CH Donors within Proteins: A Crystallographic Study
(American Chemical Society (ACS), 2016)
C-H/O interactions of aromatic C-H donors within proteins have been studied by analyzing the data in the Protein Data Bank (PDB). The C-H/O interactions were studied between aromatic donors; phenylalanine, tyrosine, and ...
Anodic luminescence, structural, photoluminescent, and photocatalytic properties of anodic oxide films grown on niobium in phosphoric acid
(Elsevier, 2015)
This article reports on properties of oxide films obtained by anodization of niobium in phosphoric acid before and after the dielectric breakdown. Weak anodic luminescence of barrier oxide films formed during the anodization ...
Formic Acid Oxidation at Platinum-Bismuth Clusters
(Electrochemical Soc Inc, Pennington, 2014)
Formic acid oxidation was studied on platinum-bismuth deposits on glassy carbon (GC) substrate. The catalysts of equimolar ratio were prepared by potentiostatic deposition using chronocoulometry. Bimetallic structures ...
Preparation and characterization of novel P(HEA/IA) hydrogels for Cd2+ ion removal from aqueous solution
(Elsevier, 2015)
Series of novel hydrogels based on 2-hydroxyethyl acrylate (HEA) and itaconic acid (IA), P(HEA/IA) copolymers, were prepared by free radical cross-linking copolymerization and investigated as potential adsorbents for Cd2+ ...
Efficient stabilization of Saccharomyces cerevisiae external invertase by immobilisation on modified beidellite nanoclays
(Elsevier Sci Ltd, Oxford, 2015)
The external invertase isoform 1 (EINV1) was immobilised on eight differently modified beidellite nanoclays, Modifications were composed of organo-modification with different amounts of surfactant - hexadecyl trimethylammonium ...
Modification of glassy carbon properties under low energy proton irradiation
(Oxford : Pergamon-Elsevier Science Ltd, 2011)
Glassy carbon plates were irradiated with 15 key H(+) ion-beam in the fluence range of 1 x 10(16)-3 x 10(18) ion cm(-2). The influence of ion irradiation on surface morphology and topology was examined by scanning electron ...
Engineered surface waves in hyperbolic metamaterials
(Optical Society of America, 2013)
We analyzed surface-wave propagation that takes place at the boundary between a semi-infinite dielectric and a multilayered metamaterial, the latter with indefinite permittivity and cut normally to the layers. Known ...
