Metal and Complementary Molecular Bioimaging in Alzheimer’s Disease
Frontiers in Aging Neuroscience, 2014 Alzheimer’s disease (AD) is the leading cause of dementia in the elderly. AD represents a complex neurological disorder which is best understood as the consequence of a number of interconnected genetic and lifestyle variables, which culminate in multiple

The nature of the fluorescent iron line in V 1486 Ori [PDF]
, 2007 The fluorescent 6.4 keV iron line provides information on cool material in the vicinity of hard X-ray sources as well as on the characteristics of the X-ray sources themselves. First discovered in the X-ray spectra of the flaring Sun, X-ray binaries and active galactic nuclei (AGN), the fluorescent line was also observed in a number of stellar X-ray ...

Improvement of 93mNb and 103mRh activity measurement methodology for reactor dosimetry
EPJ Web of Conferences, 2017 Reactor dosimetry is based on the analysis of the activity of irradiated dosimeters, such as 93mNb and 103mRh. The activity measurement of these dosimeters is conventionally performed by X-ray spectrometry, but the low-energy of emitted photons makes it ...

Biointerfacing with AgBiS2 Quantum Dots for Pseudocapacitive Photostimulation
Advanced Functional Materials, EarlyView.It is demonstrated that AgBiS2 quantum dots exhibit unique photoinduced pseudocapacitive charge transfer properties, enabling efficient light‐to‐electrical energy conversion. These quantum dots facilitate enhanced light absorption and transduction when integrated with ZnO nanowires, which serve as an effective charge transport medium.
