“I came back to Tsukuba with my college Marcin Wachowski. We spent 2 months (from 11 of October 2013 to 10 of December, 2013) in National Institute for Environmental Studies (NIES) working on missing data on calcium phosphates from my last visit. Year ago we characterized 12 nanosized apatite samples and conducted cell tests with them. This time we brought 18 more apatites to have enough data for nQSAR model.
Samples were characterized with Transmission Electron Microscopy (TEM) + Energy Dispersive X-ray Spectroscopy (EDS), Atomic Force Microscopy (AFM), Dynamic Light Scattering (DLS), Brunauer–Emmett–Teller method (BET) and some of them were imaged with Confocal Laser Scanning Microscopy (CLSM). read more >>
I have visited the University of Gdansk (UG) in Gdansk, Poland, between 31.08.2013 and 26.02.2014 as a part of Work Package: WP 5 “Development of a grouping and read-across platform for NPs”.
Participating in multi-institutional collaborative work is always important for young scientist to enhance the knowledge on his own field, and fortunately NanoBRIDGES is one of the best possible multi-institutional project on nanomaterials at current time without any doubt. Being a computational expert, I have tried to build up different QSAR models considering risk assessments of nanomaterials. Fortunately, I am working with UG before my secondment actually started since March, 2013. So, I have performed three different computational works under this project. read more >>
Between 11 October 2013 and 10 December 2013 I have visited National Institute for Environmental Studies in Tsukuba, Japan. At this time I have carried out the experiments which were necessary to produce a data about the nanoparticles. Obtained results were combined with the results received by Przemek Oberbek and Tomasz Bolek during the previous visits in NIES. The data was gathered using Transmission Electron Microscopy (TEM) with Energy Dispersive X-ray Spectroscopy (EDS), Atomic Force Microscope (AFM) and dynamic light scattering (DLS). To check cell-particles association 8 samples were investigated using confocal laser scanning microscope (CLSM). Moreover on 10 additional types of nanoparticles the experiments using BET Surface Area Measurement were carried out. At the end of the visit in Institute most of objectives from second Work Package „Carrying out experiments to produce necessary (missing) data for NPs” were achieved and necessary data for chosen NPs were gathered successfully. read more >>
I have visited National Institute for Environmental Studies (NIES) in Tsukuba Japan, for NanoBridges project implementation, second time. Now I was there 3 weeks (12th August – 2nd September 2013).
During my stay I have carried out experiments to produce necessary data for the nanoparticles. All expected data from second Work Package 2 „Carrying out experiments to produce necessary (missing) data for NPs” were collected.
Using my experience in Atomic Force Microscopy (AFM) I developed novel method for nanoparticles sample preparation and investigation in liquid environment. I tested morphology and size distribution of nanoparticles in ambient and liquid condition. Other aspect of my study was investigation of morphology of CHO (Chinese Hamster Ovary)-NF-kappa B cells, and cells – nanoparticles interaction using Confocal Laser Microscopy (CLM) methods. I have learned a lot about CLM. read more >>
I spent 12 month at the Jackson State University, Jackson, Mississippi, USA (from 3 of November 2012 to 28 October 2013), mostly carrying out experiments to check the possibility of application of carbon nanotubes as an tool in analytical chemistry.
My research focused on the development of analytical methods for the isolation of organic compounds (vitamins, ionic liquids, PAHs, sulfonamides) from water samples using carbon nanotubes as stationary phases in SPE. I also checked the possibility of use of carbon nanotubes as stationary phases in HPLC and usefulness of prepared columns for the separation of organic compounds were tested. Sorption capabilities of carbon nanotubes for the removal of sulfonamides and other organic compounds from water was also examined. Gas chromatography mass spectrometry (GC/MS), High performance liquid chromatography (HPLC), Fourier Transform Infrared Spectroscopy (FT-IR), UV-VIS spectroscopy and Bio-Lumi. Toxicity environmental tests for determination of organic compounds were used. The QSAR model was used to all obtained data. Results were presented on “Southern School on Computational Chemistry & Materials Science Conference”, and at the “10th International Symposium on Recent Advances in Environmental Health Research.” Additionally, I have participated in the Summer Institute at JSU during which, I have supervised undergraduate students working on their summer research projects. read more >>
