We enjoy measurements at Diamond synchrotron a lot, so we’re here again! This time we’re searching for gadolinium – and enjoying English tea, of course.
We attended this years Denver X-ray Conference in Big Sky, Montana from 31 July to 4 August.
This year we contributed with the following talks:
- Multimodal Imaging of Biological Samples: Correlation of μXRF with MALDI-MSI and with LA-ICP-MS (A.Turyanskaya et al.)
- Zinc (Zn) and Lead (Pb) Accumulation in the Tidemark of Articular Cartilage with High-resolution micro-XRF (M. Rauwolf et al.)
F-58 Novel Clustering Approach for the Segmentation of Elemental Distributions in Human Bone
- F-69 Implementation of a Confocal SR-microXRF System for Bone Analysis at the X-ray Fluorescence Beam Line at Elettra
- F-70 Investigation of the Local Manganese Distribution in Bone in Female and Male Osteoporosis Compared to Healthy Controls
We were once again measuring at BESSY II. From 1.5-7.5. 2017 we measured our samples with a confocal microXRF setup at the mySpot. From 8.5-11-5.2017 we did XANES (X-ray absorption near-edge structure) measurements at the neighboring BAMline.
Our group travels a lot this summer! Now we’re at the legendary European Synchrotron Radiation Facility (shortly ESRF) in France – the brightest source, the highest resolution – some 50nm and truly unique location!
Latest news from St. Petersburg! Anna Turyanskaya just delivered the talk “Elemental bioimaging in bone by µXRF” at 16th International Symposium on Trace Elements in Man and Animals (TEMA-16).Earlier this week, Dr. A. Pejovic-Milic (Ryerson Univerisity, Canada) presented the first results of joint project with our group – poster “Elemental mapping in rat bones treated with strontium ranelate and strontium citrate using µXRF”.
The Seminar Activation Analysis and Gamma Spectroscopy (SAAGAS 26), took place on 19-22 February in TU Wien, Vienna, Austria. Our group from Atominstitut contributed to the Seminar 2 oral presentations, as well as 5 posters – and three of the posters were devoted to biological samples:
- Total X-ray reflection spectrometry of black tea and herbal infusions
- μXRF spectrometer of Atominstitut in bio-imaging application
- Confocal μXRF spectrometer for low to high Z element analysis
We’re very delighted to share, that the talk of Mirjam Rauwolf – “Synchrotron radiation micro XRF analysis of zinc in osteosarcoma tissue” received an award!
The XRF-Bone team wishes you a happy new year!
And if your new year’s resolution is to read more papers, check out the early view online version of our newest paper – “Increased zinc accumulation in mineralized osteosarcoma tissue measured by confocal synchrotron radiation micro X-ray fluorescence analysis” which will be published in X-Ray Spectrometry.
Great news from Italy! First of all, the needed improvements were made on our micro-XRF laboratory setup and we are having second wonderful beamtime at X-Ray fluorescence beamline at Elettra Syncrotrone, Trieste, Italy.
What is more, the paper “(Invited) ALD to Prevent Metal Transfer from Implants” (doi: 10.1149/07506.0167ecst), which is the result of collaboration with University of Brescia (Dr. Laura Borgese, Dr. Fabjola Bilo, Dr. Annalisa Zacco, Prof. Elza Bontempi, Dr. Michela Pasquali, Dr. Stefania Federici and Prof. Laura E. Depero) and for which micro-XRF spectrometer at Atominstitut was used, has been published.
