A multi-petal adapter that enables projectiles of different sizes to be used in a single dearmer. The adapter includes a plurality of petals that are secured, in a detachable way, to a base. The main function of the base is to secure the petals until the projectile is fired from the dearmer.

The adapter fully regulates the energy imparted to the various projectiles, by allowing propellant gases to bleed through channels that are formed between the petals. As a result, the present adapter fully supports a proper projectile launch and ensures its proper orientation toward the target.

Core-shell particles encapsulated by a thin film of a catalytically active metal are described. The particles are preferably nanoparticles comprising a non-noble core with a noble metal shell which preferably do not include Pt. The non-noble metal-noble metal core-shell nanoparticles are encapsulated by a catalytically active metal which is preferably Pt. The core-shell nanoparticles are preferably formed by prolonged elevated-temperature annealing of nanoparticle alloys in an inert environment. This causes the noble metal component to surface segregate and form an atomically thin shell. The Pt overlayer is formed by a process involving the underpotential deposition of a monolayer of a non-noble metal followed by immersion in a solution comprising a Pt salt. A thin Pt layer forms via the galvanic displacement of non-noble surface atoms by more noble Pt atoms in the salt. The overall process is a robust and cost-efficient method for forming Pt-coated non-noble metal-noble metal core-shell nanoparticles.
