Synthesis of Ti <sub>4</sub> Au <sub>3</sub> C <sub>3</sub> and its derivative trilayer goldene through chemical exfoliation Open
Achieving large two-dimensional (2D) sheets of any metal is challenging due to their tendency to coalescence or cluster into 3D shapes. Recently, single-atom-thick gold sheets, termed goldene, was reported. Here, we ask if goldene can be e…
Synthesis of Ti4Au3C3 and its derivative trilayer goldene through chemical exfoliation Open
Achieving large two-dimensional (2D) sheets of any metal is challenging due to their tendency to coalescence or cluster into 3D shapes. Recently, single-atom-thick gold sheets, termed goldene, was reported1. Here, we raise the question if …
Synthesis of goldene comprising single-atom layer gold Open
The synthesis of monolayer gold has so far been limited to free-standing several-atoms-thick layers, or monolayers confined on or inside templates. Here we report the exfoliation of single-atom-thick gold achieved through wet-chemically et…
Monitoring ammonia slip from large-scale selective catalytic reduction (SCR) systems in combined heat and power generation applications with field effect gas sensors Open
Following tightened regulations, selective catalytic reduction (SCR) of nitrogen oxides (NOx) by ammonia (NH3) has over the last couple of decades found wider adoption as a means of reducing NOx emissions from e.g. power production and dis…
Synthesis of Cr2AuC via thermal substitution reaction in Au-covered Cr2GaC and Cr2GeC thin films Open
Intercalation of noble metals into non-van der Waals solids provides a new avenue to synthesize novel nanolaminated compounds with distinct material properties. Herein, we use solid-state reaction at 400 °C to prepare Cr2AuC from two Cr-ba…
Goldene: Free-standing Single-atom-thick Sheets of Gold Open
The quest to make free-standing monolayer gold has hitherto been limited to free-standing several-atoms-thick layers, or monolayers but confined on or inside another template. Examples are monolayers diffused into double hydroxides 1 , mem…
Goldene: Free-standing Single-atom-thick Sheets of Gold Open
The quest to make monolayer gold has hitherto been limited to a few atomic layers stabilized on or inside another material. Examples are monolayers diffused into double hydroxides 1 , sheets framed in Au-Ag alloys under electron irradiatio…
CO Detection Investigation at High Temperature by SiC MISFET Metal/Oxide Gas Sensors Open
In order to investigate the necessary device improvements for high-temperature CO sensing with SiC metal insulator semiconductor field effect transistor (MISFET)-based chemical gas sensors, devices employing, as the gas-sensitive gate cont…
Enabling a new method of dynamic field-effect gas sensor operation through lithium-doped tungsten oxide Open
To fulfil today's requirements, gas sensors have to become more and more sensitive and selective. Temperature-cycled operation has long been used to enhance the sensitivity and selectivity of metal-oxide semiconductor gas sensors and, more…
UV-Assisted Gate Bias Cycling in Gas-Sensitive Field-Effect Transistors Open
Static and dynamic responses of a silicon carbide field-effect transistor gas sensor have been investigated at two different gate biases in several test gases. Especially the dynamic effects are gas dependent and can be used for gas identi…
On the Applicability of Silicon Carbide Based Field Effect Sensors in the Control of Exhaust/Flue Gas After-Treatment Systems Open
The performance of Silicon Carbide based field effect gas sensor devices, modified to enable long-term reliable operation with improved sensitivity to e.g., NH3 and CO at relevant temperatures for exhaust/flue gas emissions monitoring and …
Synthesis Of Ti3Auc2, Ti3Au2C2 And Ti3Irc2 By Noble-Metal Substitution Reaction In Ti3Sic2 For High-Temperature-Stable Ohmic Contacts To Sic Open
Repository data for paper "Synthesis of Ti3AuC2, Ti3Au2C2 and Ti3IrC2 by noble-metal substitution reaction in Ti3SiC2 for high-temperature-stable ohmic contacts to SiC". Detailed information: Data from calculations include relaxed structur…
Ti<sub>2</sub>Au<sub>2</sub>C and Ti<sub>3</sub>Au<sub>2</sub>C<sub>2</sub> formed by solid state reaction of gold with Ti<sub>2</sub>AlC and Ti<sub>3</sub>AlC<sub>2</sub> Open
Ti2Au2C and Ti3Au2C2 formation by Au/Ti2AlC and Au/Ti3AlC2 exchange-reactions imply thermodynamic guidelines for identifying materials where these reactions may occur.
P5.4 - Low-cost chemical gas sensors for selective formaldehyde quantification at ppb-level in the field Open
Data from a silicon carbide based field-effect transistor were recorded over a period of nine days in a ventilated school room.For enhanced sensitivity and selectivity especially to formaldehyde, porous iridium on pulsed laser deposited tu…
Exploring the Gas Sensing Performance of Catalytic Metal/Metal Oxide 4H-SiC Field Effect Transistors Open
Gas sensitive metal/metal-oxide field effect transistors based on silicon carbide were used to study the sensor response to benzene (C 6 H 6 ) at the low parts per billion (ppb) concentration range. A combination of iridium and tungsten tr…
