“…As shown schematically in Figure a, this arrangement allowed the deposition of two Cu 3–5 μm thick masking structures with slowly degrading edges. The diamond sample was then irradiated with a 1.8 MeV He + beam at the ion microbeam line of the AN2000 accelerator of the Legnaro National Laboratories 10…”

The quantal release of catecholamines from neuroendocrine cells is a key mechanism which has been investigated with a broad range of materials and devices, among which carbon-based materials such as carbon fibers, diamond-like carbon, carbon nanotubes and nanocrystalline diamond. In the present work we demonstrate that a MeV-ion-microbeam lithographic technique can be successfully employed for the fabrication of an all-carbon miniaturized cellular bio-sensor based on graphitic micro-channels embedded in a single-crystal diamond matrix. The device was functionally characterized for the in vitro recording of quantal exocytic events from single chromaffin cells, with high sensitivity and signal-to-noise ratio, opening promising perspectives for the realization of monolithic all-carbon cellular biosensors.Submitted to 2

“…PIXE measurements were performed on samples extracted from all shards at AN2000 accelerator of LNL, INFN, Italy, with a 2 MeV proton beam [23], using macro-beam settings (beam size ~ 3 × 3 mm 2 ) and a preset charge of 4 μC. The IGLET-X ™ HPGe detector from ORTEC ® used for X-rays detection was covered [14], Fig.…”

Archaeometric investigations using OM (optical microscopy) and micro-PIXE (particle induced X-ray emission) were performed on 45 ceramic shards unearthed in archaeological excavations at Păcuiul lui Soare (southeastern Romania) and dated to the eleventh century AD. This study aimed to get clues about the raw materials and manufacturing techniques used by the potters from the Lower Danube area during the Byzantine period. The analyzed ceramic fragments were selected according to stylistic and archaeological criteria, trying to cover the entire palette of potteries discovered at this site. OM detailed the characteristics of the fabric (texture, microstructure and porosity), mineralogy, surface treatments and firing of the shards. Principal component analysis (PCA) of the PIXE data highlighted two main categories of shards with distinct compositional signatures, separated mainly by their aluminum and calcium content. Micro-PIXE maps of the interfaces between the glaze and the ceramic body showed that the green glaze is rich in lead oxide compared to the underlying ceramic body. The results of these investigations were compared to the ones previously obtained on coeval potteries from other Byzantine archaeological sites, i.e. Hârşova and Oltina, trying to get some hints about the consumption and circulation of pottery in the Lower Danube region at the beginning of the second millennium AD.

Proton irradiation on Nanocrystals Memories\ud produces peculiar radiation effects on the electrical\ud characteristics of these devices, owing to their thin tunnel oxide\ud and to the presence of nanocrystals replacing the Flash memory\ud conventional floating gate. In this work we show that the data\ud retention capability is compromised only after high fluences and\ud that irradiated devices do not show accelerated degradation\ud during subsequent electrical stresses. The presence of\ud nanocrystals instead of a floating gate reduces also the quantity\ud of charge lost during irradiation, indicating these devices as\ud possible candidates for space and avionic environment
