A Systematic Study of Methyl Carbodithioate Esters as Effective Gold Contact Groups for Single-Molecule Electronics Open
Currently, there is an array of binding groups for use within molecular electronics for anchoring molecules to metal electrodes (e.g., R–SMe, R–NH2, R–CS2−, R–S−). The problem is that some anchoring groups that bind strongly to electrodes …

Trading Agent Competition with Autonomous Economic Agents Open
In this demonstration, we introduce a system that facilitates trading agent competitions. Competitions mirror a Walrasian Exchange Economy. Each agent is endowed with a set of digital assets and preferences over them. Agents then trade the…

Cyclophane Molecules Exhibiting Thermally Activated Delayed Fluorescence: Linking Donor Units to Influence Molecular Conformation Open
The synthetic methodology to covalently link donors to form cyclophane-based thermally activated delayed fluorescence (TADF) molecules is presented. These are the first reported examples of TADF cyclophanes with "electronically innocent" b…

Democratising blockchain: A minimal agency consensus model Open
We propose a novel consensus protocol based on a hybrid approach, that combines a directed acyclic graph (DAG) and a classical chain of blocks. This architecture allows us to enforce collective block construction, minimising the monopolist…
