We demonstrate that a lightly-strained germanium channel ("// = −0.41%) in an undoped Ge/Si0.1Ge0.9 heterostructure field effect transistor supports a 2D hole gas with mobility in excess of 1 × 106 cm2/Vs and percolation density less than 5 × 1010 cm−2. This low disorder 2D hole system shows tunable fractional quantum Hall effect at low density...

We performed H-cell and flow cell experiments to study the electrochemical reduction of CO2 to oxalic acid (OA) on a lead (Pb) cathode in various nonaqueous solvents. The effects of anolyte, catholyte, supporting electrolyte, temperature, water content, and cathode potential on the Faraday efficiency (FE), current density (CD), and product...

After a 13,000-hour test campaign with aqueous 30 wt% MEA (2-aminoethanol) solvent at the CO2 capture pilot plant at Niederaussem, another long-term test was carried out as part of the ALING-CCUS project. This test ran for more than 12,275 hours with aqueous AMP/PZ (2-Amino-2-methyl-1-propanol/piperazine) solvent, named CESAR1 (3.0 molar AMP (~...

This work aims to understand oxygen solubility in pure and aqueous amine solvents for CO2 capture. Commercially available dissolved oxygen sensors were studied to evaluate whether these can be used for measuring oxygen solubility in the carbon capture processes. It also aims to understand the possible discrepansies from realistic concentrations...

Organic solvent nanofiltration (OSN) is gradually expanding from academic research to industrial implementation. The need for membranes with low and sharp molecular weight cutoffs that are able to operate under aggressive OSN conditions is increasing. However, the lack of comparable and uniform performance data frustrates the screening and...

One of the major issues encountered in the Post Combustion CO2 Capture processes is the degradation of the solvent which can be in great part attributed to the presence of oxygen in the solution. The present report focuses on the demonstration of DORA (Dissolved Oxygen Removal Apparatus), a technology developed by TNO as a counter-measure of...

An almost continuous 13,000 h long-term testing under real operating conditions was conducted at the post combustion capture pilot plant in the Niederaussem lignite-fired power plant, with a 30 wt% aqueous monoethanolamine (MEA) solvent solution. The capture plant at Niederaussem shows lower solvent consumption and emissions in comparison to...

Three dipolar aprotic solvents were designed to possess high dipolarity and low toxicity: N,N,N′,N′-tetrabutylsuccindiamide (TBSA), N,N′-diethyl-N,N′-dibutylsuccindiamide (EBSA), and N,N′-dimethyl-N,N′-dibutylsuccindiamide (MBSA). They were synthesized catalytically by using a K60 silica catalyst in a solventless system. Their water...

The ability to track & trace materials is a key feature in the entire chain, and it ensures circularity principles. Examples from plastic recycling show the enormous added value that analytical technology can have for the circular economy. During polymer production and recycling processes, pigments can be added for different purposes; e.g. as...

The use of a biorefinery co-product, such as humins, in combination with an iron precursor in a solvent-free method yields a catalytic material with potential use in selective oxidative cleavage reactions. In particular, this catalyst was found active in the hydrogen-peroxide assisted oxidation of a naturally extracted molecule, isoeugenol, to...

The one-pot conversion of glucose to ethyl levulinate over an acid-functionalised hydrothermal catalyst (derived from glucose) provides high initial yields up to 37 mol%, comparable to the homogeneous H2SO4 catalyst, whilst catalyst performance is strongly influenced by green solvent choice.

In this work, quaternary and non-quaternary oximes designed to bind at the peripheral site of acetylcholinesterase previously inhibited by organophosphates were investigated theoretically. Some of those oximes have a large number of degrees of freedom, thus requiring an accurate method to obtain molecular geometries. For this reason, the density...

The present study has established the direct pseudo–first-order reaction kinetics of different aqueous-based single and blended amines over the temperature range of 298.15-313.15 K using stopped-flow techniques. The single amines include one primary amine (monoethanolamine, MEA), two secondary amines (diethanolamine, DEA and 2-ethyl(amino...

Oxidative degradation is a serious concern for upscaling of amine-based carbon capture technology. Different kinetic models have been proposed based on laboratory experiments, however the kinetic parameters included are limited to those relevant for a lab-scale system and not a capture plant. Besides, most of the models fail to recognize the...

Degradation of amines is one of the most important issues to be addressed for absorption-desorption based post-combustion CO2 capture. Several laboratory studies have been performed to identify the degradation products and understand the mechanisms of degradation. However, there seems to be a gap in knowledge from translating the lab scale...
