An improved AMBER force field for alpha,alpha-dialkylated peptides: intrinsic and solvent-induced conformational preferences of model systems
(Royal Soc Chemistry, Cambridge, 2013)
alpha,alpha-Dialkylated amino acid residues have acquired considerable importance as effective means for introducing backbone conformation constraints in synthetic peptides. The prototype of such a class of residues, namely ...
The effect of rhodium nanoislands on the electrocatalytic activity of gold for oxygen reduction in perchloric acid solution
(Elsevier, 2013)
The effect of spontaneously deposited rhodium nanoislands on the electrocatalytic activity of polycrystalline gold, Au(poly), for oxygen reduction reaction (ORR) was studied using rotating disc electrode technique in 0.1 ...
The influence of water molecule coordination onto the water-aromatic interaction. Strong interactions of water coordinating to a metal ion
(Royal Soc Chemistry, Cambridge, 2013)
The interactions between water molecules (non-coordinating and coordinating) and aromatic rings were studied by analyzing data in the Cambridge Structural Database and by quantum chemical calculations. The results show the ...
Studies of the regioselective ring-opening closing mode of functionally different thiazolidine type enaminones: en route to the synthesis of trithiaazapentalene derivatives
(Oxford : Pergamon-Elsevier Science Ltd, 2013)
Trithiaazapentalene derivatives were prepared by the reaction of 2-alkylidene-4-oxothiazolidines with Lawesson's reagent. They are classified as two structurally different trithiaazapentalene compounds that have different ...
Characterization of lead sorption by the natural and Fe(III)-modified zeolite
(Elsevier, 2013)
The influence of contact time, temperature and particle size on lead sorption by the natural and Fe(III)-modified zeolites was investigated. Characterization of the natural and Fe(III)-modified zeolite before and after ...
The Predicted Spectrum and Singlet-Triplet Interaction of the Hypermetallic Molecule SrOSr
(American Chemical Society (ACS), 2013)
In accordance with previous studies in our group on Be, Mg, and Ca hypermetallic oxides, we find that SrOSr has a linear (X) over tilde (1)Sigma(+)(g) ground electronic state and a very low lying first excited (a) over ...
Double Asymmetric Induction in Organocatalyzed Aldol Reactions: Total Synthesis of (+)-2-epi-Hyacinthacine A(2) and (-)-3-epi-Hyacinthacine A(1)
(Wiley-V C H Verlag Gmbh, Weinheim, 2013)
The stereodivergent synthesis of two hyacinthacine analogues, which relies on an organocatalyzed aldol addition, is described. The aldol addition of dioxanone to an -N-carbobenzyloxy-substituted chiral aldehyde, promoted ...
Synthesis, Electrochemistry, and Hierarchical Self-Organization of Fulleropyrrolidine-Phthalimide Dyads
(Wiley-V C H Verlag Gmbh, Weinheim, 2013)
A series of novel fulleropyrrolidine-phthalimide dyads was synthesized and their electrochemical and self-assembly properties were investigated. Efficient synthesis of acceptor-acceptor dyads was performed under microwave ...
Experimental Design in Formulation of Diazepam Nanoemulsions: Physicochemical and Pharmacokinetic Performances
(Wiley-Blackwell, Hoboken, 2013)
With the aid of experimental design, we developed and characterized nanoemulsions for parenteral drug delivery. Formulations containing a mixture of medium-chain triglycerides and soybean oil as oil phase, lecithin ...
Preparation and photocatalyic properties of TiO2-P25 film prepared by spray pyrolysis method
(Elsevier, 2013)
TiO2 films were synthesized by immobilization of Degussa P25 powders on stainless steel support by spray pyrolysis technique. After preparation, the films were annealed at different temperatures in order to obtain materials ...
