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 کاملRaw material ‘ criticality ’ — sense or nonsense ?
The past decade has seen a resurgence of interest in the supply security of mineral raw materials. A key to the current debate is the concept of ‘criticality’. The present article reviews the criticality concept, as well as the methodologies used in its assessment, including a critical evaluation of their validity in view of classical risk theory. Furthermore, it discusses a number of risks pre...
متن کاملLearning Common Sense Through Visual Abstraction Supplementary Material
We first detail the webpages with qualitative results in Section 1. We then discuss our procedure for extracting commonsense tuples from sentences (Section 2). We give examples of the data we collect about relations via Abstract Scenes which includes the illustrations drawn by users and the tuples provided by them (Section 3). We then show our interface for collecting ground truth on plausibili...
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.
