X-Ray Analysis
Synchrotron X-rays from a Tabletop - Highly Energetic, Bright and Spatially Coherent
Since their discovery in 1896 [1], x-rays have fundamentally revolutionized science, medicine and technology. Each successive generation of x-ray machines has opened up new frontiers in science, such as the first radiographs and the determination of the structure of DNA. State-of-the-art x-ray sources, such as synchrotrons, can now produce coherent high-brightness beams of x-rays with energies greater than kiloelectronvolt, which promise a new revolution in imaging complex systems on the nanometer and femtosecond scale. more
X-Ray Analysis Reveals Protein-chitin Complex in Fossils of Arthropods from the Palaeozoic Era
X-ray Analysis at the Advanced Light Source facility in the USA shows that, contrary to conventional belief, remains of chitin-protein complex - structural materials containing protein and polysaccharide -are present in abundance in fossils of arthropods from the Palaeozoic era. more
X-ray Analysis Show Why van Gogh Paintings Lose their Shine
Scientists have identified a complex chemical reaction responsible for the degradation of two paintings by Vincent van Gogh and other artists of the late 19th century. This discovery is a first step towards understanding how to stop the bright yellow colours of van Gogh's most famous paintings from becoming covered by a brown shade, and fading over time. In the meantime, the results suggest shielding affected paintings as much as possible from UV and sunlight. more
XRF Analysis
Analysing minerals, ceramics and similar samples by XRF, the Vulcan fusion system, distributed in the UK by Analysco, uses automatic fusion control to achieve better sample uniformity and repeatability.more
New X-Ray Microscope
We know a wide variety of X-ray applications in everyday life. For example, medical X-rays or baggage screening at airports allow non-destructive insights into the interior of objects. more
Microneedle Drug Delivery Technology
Michelson Diagnostics is pleased to report the use of its VivoSight OCT imaging system to evaluate the performance of a new microneedle drug delivery technology by researchers at Queen's University Belfast led by Dr Ryan Donnelly. The research, to be published in the Journal of Controlled Release*1, shows how the VivoSight system was used to directly image the microneedles penetrating the skin, and how the results were used to evaluate the effects of microneedle spacing and force of application. more
New X-ray Source
In a major boost for X-ray science and accelerator physics, the National Science Foundation (NSF) has committed about US-$ 109 million to Cornell's continued operation of an X-ray synchrotron facility, as well as to develop a new kind of X-ray source that promises to revolutionize the field. more
HRSEM Study of Sn-Zn-Cu Film Formation
The formation of CuInSe2 and Cu2ZnSnSe4 thin films in the process of selenization precursor films was studied in use of combined microscopic (HRSEM) and spectroscopic (micro-XRF, EDS, micro-Raman and XRD) methods. more
Advances in µ - XRF
The macroscopic properties of technical materials are often determined by their elemental composition. Because most technical materials are inhomogeneous analytical methods are required that allow elemental analysis of these inhomogeneities - not only as a point by point measurement but also as a complete 2D-distribution. Micro X-ray fluorescence (µ XRF) has recently been established for this purpose. more
SEM/EDX-Analysis in Art History
Material analysis in art historical research provides information on dating, tracing the process of origin and state of preservation of art objects. Usually XRF and optical spectroscopy are used to study pigments in paintings. However these methods suffer from poor spatial resolution and therefore can not be used for the analysis of the layer structure of paintings. In these cases high resolution methods like SEM/EDX are indispensable. more- Legal
