Composites based on graphite oxide and zirconium phthalocyanines with aromatic amino acids as photoactive materials

Fabrication of a yellow ceramic nano pigment based on zirconium oxide (ZrO2) and iron oxide as dopant (Fe2O3)

In this study, yellow ceramic nano pigments based on ZrO2 (zirconium oxide) were synthesized by solid state method using different value of Fe2O3 as dopant. The pigments were dispersed in solvent by a planetary ball mill and then the inks were printed on the ceramic surface using screen printing method. The samples were analyzed using scanning electron microscopy (SEM), X-ray diffraction spectr...

Graphite oxide - based graphene materials as positive electrodes in vanadium redox flow batteries

Two graphene materials, TRGO-1 and TRGO-2, prepared by the thermal exfoliation/reduction at 1000oC of two graphite oxides with different characteristics, are investigated as positive electrodes in a Vanadium Redox Flow Battery (VRFB). A detailed study of their electrochemical response towards the [VO2]/[VO] redox system is carried out through cyclic voltammetry, electrochemical impedance spectr...

Translucency and strength of high-translucency monolithic zirconium oxide materials.

The purpose of this study was to evaluate the translucency and strength of highly translucent monolithic zirconia ceramic materials recently introduced to the market. Four monolithic zirconium oxide materials promoted as having high translucency (BruxZir Shaded 16, BruxZir HT, Lava Plus, and inCoris TZI C) were compared to a high-translucency, lithium disilicate monolithic glass-ceramic materia...

Cation-p Interactions Involving Aromatic Amino Acids

The cation-p interaction is a general, strong, noncovalent binding force that is used throughout nature. The side chains of the aromatic amino acids [phenylalanine (Phe), tyrosine (Tyr), and tryptophan (Trp)] provide a surface of negative electrostatic potential than can bind to a wide range of cations through a predominantly electrostatic interaction. In this brief overview, the fundamental na...
