Comparison of gamma-ray coincidence and low-background gamma-ray singles spectrometry

2011

Aerosol samples have been studied under different background conditions using gamma-ray coincidence and low-background gamma-ray singles spectrometric techniques with High-Purity Germanium detectors. Conventional low-background gamma-ray singles counting is a competitive technique when compared to the gamma-gamma coincidence approach in elevated background conditions. However, measurement of gamma-gamma coincidences can clearly make the identification of different nuclides more reliable and efficient than using singles spectrometry alone. The optimum solution would be a low-background counting station capable of both singles and gamma-gamma coincidence spectrometry.

Electric current induced modification of germanium nanowire NEM switch contact.

2015

We present an investigation of contact properties of a germanium (Ge) nanowire based nanoelectromechanical (NEM) switch in its ON state. The contact stiffness in the ON state was evaluated by detecting the nanowire's resonance frequency. It was found that the resonance frequency increases when electric current flows through the nanowire/counter electrode contact area. The reason for modification in the contact area is referred to as electric-current-induced processes in the native oxide layer covering the nanowires. The presented resonance shift method is a simple way to indicate strengthening of the nanowire/counter electrode contact area without disassembling the contact.

L'esercizio dell'azione e il giudizio di prima istanza, tra ordinamento italiano e tedesco. Spunti comparatistici a margine dell'opera di Manfred Mai…

2010

Premettendo alcune considerazioni sulle finalità della ricerca comparatistica, l''Autore mette a confronto alcuni istituti del processo penale italiano e di quello tedesco, facendo particolare riferimento al momento dell''esercizio dell''azione e al giudizio di primo grado. Oltre alle diversità di fondo, vengono evidenziate le principali questioni interpretative e le iniziative di riforma affacciatesi in relazione ai due sistemi, per verificare il rispettivo livello di rispondenza di questi ultimi alle istanze maturate sul piano europeo.

Croce e la modernità tedesca

2017

The book collects the proceedings of the international symposium held with the support of the DFG in 2016 at Villa Vigoni about the relationship between Benedetto Croce and German culture. In particular, the essays deal with the question of the crisis of modernity in German culture through a spectrum of inquiries ranging from Kant to Th. Mann. Il volume costituisce l'edizione italiana dei materiali del seminario internazionale svoltosi con il sostegno della DFG nel 2016 presso Villa Vigoni, avente per argomento il ruolo di Croce in Germania e della cultura tedesca per Croce. In particolare, i singoli contributi affrontano la questione della crisi della modernità nella cultura tedesca in uno…

An easy route to 1-germaindenes via a transmetallation zirconiumgermanium reaction

1993

Abstract Several 1-zirconaindenes ( 4 ) have been obtained easily by heating phenylmethylzirconocene with various symmetrical (R  R′  CH 3 , C 2 H 5 , n-C 3 H 7 , Si(CH 3 ) 3 and unsymmetrical (R  CH 3 , R′  Si(CH 3 ) 3 ) alkynes (RCCR′). Under similar experimental conditions, the ynamine, diethylaminotrimethylsilylethyne, led to a regioselective reaction. From the X-ray structure of the zirconaindene product, the trimethylsilyl group was found close to the zirconium atom. Compounds 4 with germanium tetrachloride afford new 1-germaindenes ( 7 ) characterized by 1 H and 13 C NMR and mass spectrometry, in good yield.

Separation and purification of no-carrier-added arsenic from bulk amounts of germanium for use in radiopharmaceutical labelling

2010

AbstractRadioarsenic labelled radiopharmaceuticals could add special features to molecular imaging with positron emission tomography (PET). For example the long physical half-lives of72As (T1/2=26 h) and74As (T1/2=17.8 d) in conjunction with their high positron branching rates of 88% and 29%, respectively, allow the investigation of slow physiological or metabolical processes, like the enrichment and biodistribution of monoclonal antibodies in tumour tissue or the characterization of stem cell trafficking. A method for separation and purification of no-carrier-added (nca) arsenic from irradiated metallic germanium targets based on distillation and anion exchange is developed. It finally con…
