  1. Conductometric study of calcium carbonate prenucleation stage: underlining the role of CaCO3o ion pairs

    During the prenucleation stage, the process begins with the formation of CaCO3° ion pairs as pre-nuclei. With pH increase and then with the supersaturation coefficient, the number of these entities rises to form aggregates. Aggregation leads to the formation of stable nuclei which will later evolve to crystallize.

    This figure shows the effects of solvents on structure and morphology of ZnO photocatalysts. TEM images showed that ZnO crystalline had different growth habits in different solvents. Also, ZnO nanorods exhibit superior photocatalytic activity in the degradation of RhB compared to other samples. (a) without catalyst, (b) microellipses, (c) microdisks, and (d) nanorods.

  3. Crystal growth of progesterone metastable and stable polymorphs by polymer induced herteronucleation (PIHn) method

    Progesterone form 2 (metastable and more soluble polymorph) was crystallized on PVA, HPMC and gelatin from high concentration solutions. This polymorph was stable under stress conditions for three months on HPMC. Therefore, devices loaded by this polymorph might need lower doses with the same bioavailability. This is a great advantage for pharmaceutical applications and these results are good evidence that the tailoring of new formulations and devices with progesterone form 2 is possible.

  4. Preparation, characterization and in vitro assessment of ibuprofen loaded calcium phosphate/gypsum bone cements

    In the present study, pure apatite, and apatite/gypsum composite self-setting cements were prepared. Characterization of the hardened cements showed the transformation of α-TCP to low crystalline apatite and calcium sulfate dihydrate to gypsum. The drug release studies showed that by using different cement compositions it may be possible to ‘fine tune’ the release rate of the anti-inflammatory drug Ibuprofen.

  5. XPS and AFM studies of surface chemistry and morphology of In2O3 ultrathin films deposited by rheotaxial growth and vacuum oxidation after air exposure

    We present the results of XPS study of the surface chemistry of In2O3 ultrathin deposited by RGVO after their air exposure and subsequent UHV annealing. For the freshly deposited RGVO IO ultrathin films the relative [O]/[In] concentration is equal to 1.17 and after UHV annealing at 350 °C this slightly increases to 1.30. The AFM experiments showed that ultrathin films exhibit the granular-type surface morphology, with an average roughness of 1.1 nm.
