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 ...
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+ ...
Chromium (VI) removal from aqueous solutions using mercaptosilane functionalized sepiolites
(Elsevier, 2011)
Natural and acid-activated sepiolite samples were functionalized with (3-Mercaptopropyl)trimethoxysilane.
By X-ray powder diffraction, Fourier transform infrared spectroscopy, and differential thermal
analysis it was ...
Stacking Interactions between Square-Planar Metal Complexes with 2,2'-Bipyridine Ligands. Analysis of Crystal Structures and Quantum Chemical Calculations
(American Chemical Society (ACS), 2014)
Stacking interactions between square-planar metal complexes containing bipyridine ligands (bipy) were studied by analyzing data in the Cambridge Structural Database (CSD) and by density functional theory (DFT) calculations. ...
An exergy composite curves approach for the design of optimum multi-pressure organic Rankine cycle processes
(Oxford : Pergamon-Elsevier Science Ltd, 2014)
This work adopts the (ECCs) under bar (exergy composite curves) approach to explore the potential for ORC (organic Rankine cycle) process improvements. The method is used to explore different ORC configurations supported ...
Characterization of nanoporous carbon fibrous materials obtained by chemical activation of plane tree seed under ultrasonic irradiation
(Elsevier, 2014)
An ultrasonic irradiation was applied for the impregnation by chemical agents in the chemical activation process of new type of active carbon precursor. Plane tree seed, due to the unique fibrous structure and low cost is ...
Two nitro derivatives of azabenzo[a]pyrene N-oxide: Electronic properties and their relation to mutagenic activity
(Elsevier, 2015)
The equilibrium geometries, relative energies, IR and Raman spectra, vertical ionization potentials (IP), vertical electron affinities (EA), dipole moments (mu), electronic dipole polarizabilities (alpha), and molecular ...
Porous carbon thin films for electrochemical capacitors
(Oxford : Pergamon-Elsevier Science Ltd, 2013)
Activation effects on carbon films, derived from commercial aromatic polyimide films (Kapton, DuPont), in CO2 atmosphere at 1203 K on capacitance properties were studied. Two thicknesses of polyimide films were used: 7 and ...
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 ...
On the role of working fluid properties in Organic Rankine Cycle performance
(Oxford : Pergamon-Elsevier Science Ltd, 2012)
The performance of ORC systems strongly depends on working fluid properties. We explore the relationships between working fluid properties and ORC common economic and thermodynamic performance criteria from a theoretical ...
