Material witness: quantum writ large.
430 nature materials | VOL 7 | JUNE 2008 | www.nature.com/naturematerials salts — the charged material causes the reduction of Cu2+ ions to Cu metal and the latter is deposited on the electrode (Fig. 1b). By analysis of the product, the charge density is estimated to be similar to that found in the previous experiment, around 7 × 1014 cm–2. Further electrochemical reactions were possible — incl...
متن کاملMaterial witness: A quick fix.
M AERIA L W TN SS Delicately patterned microand nanostructures can be produced without the need for laborious fabrication, by relying on physical forces to organize materials spontaneously into intricate forms. The capacity of soft materials such as surfactants and block copolymers to self-organize into regular patterns has been long recognized1–3, and superlattices and other ordered arrays in ...
متن کاملGallium platinum alloys – a new material system for UV plasmonics
We describe a new material system based on alloys of gallium and platinum that is well-suited for ultraviolet (UV) plasmonics. Although gallium has previously been shown to be useful for such studies, creating a continuous, pinhole-free thin film has been technically challenging. For example, when vacuum deposition techniques are used, gallium forms as isolated spherical nanoparticles on a wide...
متن کاملWitness Sets
Given a set C of binary n-tuples and c ∈ C, how many bits of c suffice to distinguish it from the other elements in C ? We shed new light on this old combinatorial problem and improve on previously known bounds.
متن کاملDelegateable Signature Using Witness Indistinguishable and Witness Hiding Proofs
A delegateable signature scheme is a signature scheme where the owner of the signing key(Alice) can securely delegate to another party(Bob) the ability to sign on Alice’s behalf on a restricted subset S of the message space. Barak first defined and constructed this signature scheme using non-interactive zero-knowledge proof of knowledge(NIZKPK)[1]. In his delegateable signature scheme, the func...
