With global concerns about the shortage of fossil fuels and environmental issues, the development of efficient and clean energy storage devices has been drastically accelerated. Nanofibers are used widely for energy storage devices due to their high surface areas and porosities. Electrospinning is a versatile and efficient fabrication method for nanofibers.(More)
Nickel is set to play a crucial role to substitute the less-abundant platinum in clean electrochemical energy conversion and storage devices and catalysis. The controlled design of Ni nanomaterials is essential to fine-tune their properties to match these applications. A systematic study of electrospinning and thermal post-treatment parameters has been(More)
Our paper reports on an ongoing experiment aiming to use broadly principles and methods from virtual reality and augmented reality for didactical purposes. The specific field in which these methodologies have been proposed, studied and implemented, at a first stage, is in teaching physics, in particular, kinematics. Key idea is that of providing the(More)
The layout of the RPCs, used in the Argo-YBJ experiment to image with a high space-time granularity the atmospheric shower, is described in this paper. The detector has been assembled to provide both digital and analog informations in order to cover a wide particle density range with a time accuracy of 1 ns. The experimental results obtained operating the(More)
The ARGO-YBJ experiment has been designed to study the Extensive Air Showers with an energy threshold lower than that of the existing arrays by exploiting the high altitude location (4300 m a.s.l. in Tibet, P.R. China) and the full ground plane coverage. The lower energy limit of the detector (E ∼ 1 GeV) is reached by the scaler mode technique, i.e.(More)
An RPC carpet covering &10 m (ARGO-YBJ experiment) will be installed in the YangBaJing Laboratory (Tibet, People's Republic of China) at an altitude of 4300 m a.s.l. A test-module of &50 m has been put in operation in this 0168-9002/00/$-see front matter 2000 Elsevier Science B.V. All rights reserved. PII: S 0 1 6 8-9 0 0 2 (0 0) 0 0 9 7 6-1 LARGE SYSTEMS(More)
