Ion Beam Analysis and 14C Accelerator Mass Spectroscopy to Identify Ancient and Recent Art Forgeries

Accelerator-based ion beam analysis of fusion reactor materials

First wall components in controlled fusion devices undergo severe modification by various physical and chemical processes arising from plasma–material interactions: material erosion, its migration in the plasma and re-deposition. Ion beam analysis techniques play a prominent role in the studies of wall components exposed to hot plasmas. The intention of this work is to give a concise overview o...

Macromolecular ion accelerator mass spectrometer.

We present a newly developed macromolecular ion accelerator mass spectrometer that combines a dual-ion-trap device and a macromolecular ion accelerator (MIA) to achieve the capability of analyzing samples with a mixture of large biomolecules. MIA greatly increases detection efficiency. The dual ion trap includes a quadrupole ion trap (QIT) and a linear ion trap (LIT) in tandem. The dual ion tra...

the differential effects of debate and media analysis as relate to enhancing efl learners critical thinking ability and writing performances

critical thinking ability has an important role in education. accordingly, scholars around the world are searching for new ways for teaching and improving students critical thinking ability. in line with the studies in efl contexts supporting the positive relationship between critical thinking and writing performances, this study investigated the differential effects of halverson’s critical thi...

A Survey of Art Forgeries

Biomedical accelerator mass spectrometry: recent applications in metabolism and pharmacokinetics.

BACKGROUND Accelerator mass spectrometry (AMS) is a sensitive isotope ratio technique used in drug development that allows for small levels of 14C-drug to be administered to humans, thereby removing regulatory hurdles associated with radiotracer studies. AMS uses innovative study designs to obtain pharmacokinetic and metabolism data. OBJECTIVE This review addresses the metabolism and pharmaco...
