Separation and Valorization of Chlorine From Tail Gas Streams
Angewandte Chemie International Edition, EarlyView.A commercially available ion exchange resin was found to adsorb chlorine gas selectively in the presence of other gases reversibly forming the corresponding trichloride species [IEx][Cl3]. This discovery was telescoped to an efficient process for the recycling and valorization of chlorine from industrially abundant tail gas streams to base chemicals ...

Proceedings of International Europhysics Conference on High Energy Physics — PoS(HEP2005), 2007 MAGIC (Major Atmospheric Gamma Imaging Cherenkov telescope) is presently the largest ground-based gamma ray telescope. MAGIC has been taking data regularly since October 2004 at the Roque de los Muchachos Observatory on the island of La Palma. In this paper the MAGIC telescope status, its performances and some preliminary results on observed gamma ray ...

Mezzocielo: An attempt to redesign the concept of wide field telescopes
, 2020 Mezzocielo (or "half of the sky") is a concept for a new class of telescopes where a full spherical optical surface is made by filling with a liquid a structure built up with spherical lenses and almost covering an entire sphere. Lenses of the same class

The attenuation of atmospheric Cerenkov photons [PDF]
, 2002 Whilst the atmosphere places a limit on the successful applications of many branches of astronomy, it becomes an invaluable tool for the detection of very high energy γ-rays. This thesis is concerned with reducing the systematic uncertainties inherent to

Direct SMBH Formation Driven by Runaway Stellar Collisions in Globally Unstable Stellar Systems
Astronomische Nachrichten, EarlyView.ABSTRACT The fueling problem addresses the ultimate fate of the reservoirs of gas and stars driven into the deepest gravitational potential wells of galaxies, thus it may contain the Universe's densest concentrations of gas and stars. This raises a key question: does the infalling material collapse directly into a supermassive black hole, or can it ...
