Pulsed Laser Deposition of Si Nanocluster Films
Reactive laser ablation of Si targets by ArF* excimer laser (wavelength 193 nm, pulse width 15 ns (FWHM)) was performed in He, Ar or O2 0.05–1 Torr atmospheres and led to Si-SiOx nanocluster thin film formation w...

Enhancement of intramammary lymph nodes with lymphoid hyperplasia: a potential pitfall in breast MRI
We present three cases of breast lesions labeled as probable intramammary lymph nodes that showed an increase in size on follow-up mammography. Contrast-enhanced MRI was performed and the three lesions showed...

Synthesis and properties of Si and Ge nanoclusters produced by pulsed laser ablation
We show that conventional pulsed laser ablation (PLA) of Si and Ge targets in inert buffer gases is an efficient method of nanocluster synthesis. From a photoluminescence study of Si and Ge nanoclusters produ...
