I have visited Jackson State University, Jackson, Mississippi, USA between 03.11.2012 and 28.10.2013 (12 months) within Work Package 2.
The aim of my work was firstly to develop a sampling and analysis method for the determination of chlorophenols and other organic compounds in water, using SPE to collect and concentrate the chlorophenols. The study estimated the influence of different variables which could affect the SPE extraction efficiency – including the type of CNTs, elution solvent, elution volume and elution flow-rate. I hope that my work will be continued by implementing the obtained experimental results in development of analytical methods. Using CNTs as a new solid phase extraction sorbent I have identified and quantified organic compounds in water, soil and sediments collected within Jackson, MS. I have evaluated the toxicity of various organic compounds by Bio-Lumi Toxicity environmental tests. All obtained experimental results were implemented in a QSAR model. Gas chromatography mass spectrometry (GC-MS), High performance liquid chromatography (HPLC), Fourier Transform Infrared Spectroscopy (FT-IR) and UV-VIS spectroscopy were used for the determination of organic compounds. read more >>
I have visited National Institute for Environmental Studies (NIES) in Tsukuba (Japan) for 3 months (1.05 – 29.07.2013) within Work Package 2: Carrying out experiments to produce necessary (missing) data for nanoparticles.
The noble metal modified titanium dioxide photocatalysts prepared by water in oil microemulsion and sol-gel method were successively tested. The aim of the study was to evaluate potential health risk and physical properties of the nanomaterials by Specific Suraface Area analysis, Atomic Force Microscope, X-ray diffraction and toxicity measurements (carried out by dr. Ewa Mulkiewicz ). XRD patterns showed that calcination in the 400 °C results in anatase formation, which is the most required crystallographic form in the industry. Correlation between preparation method, amount of various noble metal (Ag, Pt, Au), type of crystal structure and their influence on cells respond has been created. read more >>
My visit at the Jackson State University, Jackson, Mississippi, USA was held from 16 February to 16 August 2013 as a part of WP6: Dissemination and uptake of the NanoBRIDGES project results.
Program of my research activities included dissemination of obtained results at the conferences: Southern School on Computational Chemistry & Materials Science Conference (Carbon nanotubes as an ion carriers in electrodeposition of hydroxyapatite coating on titanium alloy), and at the 10th International Symposium on Recent Advances in Environmental Health Research (Fabrication of hydroxyapatite-graphene composite coating on porous titanium scaffolds). read more >>
We visited the Warsaw University of Technology, Warsaw, Poland, between 01.07.2013 and 31.07.2013 within WP 2 “Carrying out experiments to produce necessary data for NPs of apatites”.
During our stay at WUT, We have obtained a large number of empirical data on the structure and size of particles investigated apatites. The data can be useful for computational modeling of toxic potential of different apatites. It was very beneficial for us as researcher to familiarize with methods for study of an average size of apatite particles. We synthesized at PCI, NAS of Ukraine (PCI) in Odessa more than 20 materials and composites based on hydroxy- and fluorapatites, including partially substituted ones. read more >>
This short visit (13-24.08.2013) has been conducted within BRIDGE II: Exchanging ideas developed simultaneously by different groups with similar profiles (computational-computational).
During a seminar and general meeting we have exchanged information on the progress in the development of computational and methods within NanoBRIDGES project. We have discussed advantages and disadvantages of using four systems for describing nanoprticles’ structure, namely: (i) physico-chemical, interfacial, and processing parameters; (ii) descriptors derived from quantum-mechanical calculations; (iii) descriptors derived from computational processing of microscopic (SEM/TEM/AFM) images of the particles; (iv) descriptors based on anisotropy dimensions, as proposed by Glotzer and Solomon. read more >>
