McNaughter,Aleksander A. Tedstone,Nicky Savjani,Christopher A. Muryn,Paul O'Brien,Ashok K. Ganguli,David J. Lewis,Priyanka Sabherwal +20 more
TL;DR: The electrochemical detection of the redox active cardiac biomarker myoglobin using aptamer-functionalized black phosphorus nanostructured electrodes by measuring direct electron transfer is reported, opening up avenues to bedside technologies for multiplexed diagnosis of cardiovascular diseases in complex human samples.
Journal ArticleDOI
Structure and electronic properties of in situ synthesized single-layer MoS2 on a gold surface.
TL;DR: The MoS2/Au system is proposed as a promising candidate to further explore the properties of supported 2D transition-metal dichalcogenides in the context of nanopatterned two-dimensional materials on metal surfaces.
Journal ArticleDOI
In Situ Detection of Active Edge Sites in Single-Layer MoS2 Catalysts.
Albert Bruix,Henrik Goebel Füchtbauer,Anders Tuxen,Alex S. Walton,Mie Andersen,Soeren Porsgaard,Flemming Besenbacher,Bjørk Hammer,Jeppe V. Lauritsen +8 more
TL;DR: Ambient pressure X-ray Photoelectron Spectroscopy allows us to follow in situ the formation of the catalytically relevant MoS2 edge sites in their active state, and a consistent picture emerges in which the core level shifts for the edge Mo atoms evolve counterintuitively toward higher binding energies when the active edges are reduced.
Journal ArticleDOI
Synthesis of High‐Surface‐Area Platinum Nanotubes Using a Viral Template
TL;DR: In this article, a method for the synthesis of high-active surface area, platinum-tobacco mosaic virus (Pt-TMV) nanotubes is presented, where a platinum salt is reduced to its metallic form on the external surface of a rod-shaped TMV by methanol.
Journal ArticleDOI
Edge reactivity and water-assisted dissociation on cobalt oxide nanoislands.
Jakob Fester,Max García-Melchor,Max García-Melchor,Alex S. Walton,Michal Bajdich,Zhongshan Li,Lutz Lammich,Aleksandra Vojvodic,Jeppe V. Lauritsen +8 more
TL;DR: Surprisingly, it is found that an additional water molecule acts to promote all the elementary steps of the dissociation process and subsequent hydrogen migration, revealing the important assisting role of a water molecule in its own Dissociation process on a metal oxide.
