A Survey on the Applications of Zero-Knowledge Proofs

Autor: Lavin, Ryan, Liu, Xuekai, Mohanty, Hardhik, Norman, Logan, Zaarour, Giovanni, Krishnamachari, Bhaskar

Zero-knowledge proofs (ZKPs) represent a revolutionary advance in computational integrity and privacy technology, enabling the secure and private exchange of information without revealing underlying private data. ZKPs have unique advantages in terms

Compatibility of Gelled Inhibited Red Fuming Nitric Acid with Aluminum Alloys

Autor: Ramona E. Arndt Hallit, Norman Logan, Barry D. Allan, Clark W. Hawk

Publikováno v: Journal of Propulsion and Power. 13:481-487

This paper presents data obtained from electrochemical methods, weight loss studies, and surface studies to determine compatibility of gelled inhibited red fuming nitric acid (IRFNA) with aluminum alloys. Comparisons are presented between liquid IRFN

Laboratory methodologies for propellant corrosion research

Autor: Jeremy P. Mauger, Clark W. Hawk, Ramona E. Arndt, Norman Logan, Barry D. Allan, Michael F. A. Dove

Publikováno v: Journal of Propulsion and Power. 12:580-584

Storable liquid propellants are stored for extended periods of time in metal tankage prior to usage in rocket engines. Knowing the chemical interaction of the propellant and the tankage material is essential to evaluating the structural integrity of

The reaction of ionic nitrites with liquid dinitrogen tetraoxide

Autor: Norman Logan, Simon A. Wood, Michael F. A. Dove, Stephen Arrowsmith, C. Clifford Addison, Brian F.G. Johnson

Publikováno v: Polyhedron. 15:781-784

The reaction of nitrites of Na + , Bu 4 n N + and Ni 2+ with liquid dinitrogen tetraoxide and the factors affecting the rate and extent of the reaction have been studied. Oxidation occurs to the corresponding nitrate in a manner consistent only with

Corrosion of Ti-6Al-4V alloy and 304L stainless steel in liquid nitrogen oxides

Autor: Simon A. Wood, Norman Logan, Michael F. A. Dove

Publikováno v: Journal of Propulsion and Power. 12:48-54

Liquid dinitrogen tetroxide is normally stored in stainless steel tanks, whereas the mixed oxides of nitrogen, dinitrogen tetroxide plus nitric oxide, may also be stored in titanium alloy vessels. This article presents new data on the corrosion of un
