Dataset of "Fast carbon dioxide–epoxide cycloaddition catalyzed by metal and metal-free ionic liquids for designing non-isocyanate polyurethanes"
<p>The recycling of industrially produced greenhouse gases, such as CO2, into high-value-added chemicals is one of the most relevant strategies for reaching climate targets. A two-step strategy for designing non-isocyanate polyurethanes (NIPUs) from renewable carbon dioxide (CO2) using environmentally friendly conditions and catalysts is investigated. The first reaction step efficiently converts a mono-epoxidized monomer (phenyl glycidyl ether) into cyclic carbonates under mild reaction conditions and supercritical CO2, using imidazolium ionic liquids (ILs) as catalysts into cyclic carbonates. The DFT calculations suggested a comprehensive mechanistic pathway for the IL-catalyzed CO2-epoxy reaction showing a rate-determining step of the initial epoxide ring opening and the direct participation of IL-anions.</p>

Techno-economic model of Methane pyrolysis in liquid metal bubble column reactor for hydrogen direct reduction of iron ore
<p>Reducing emissions from the iron and steel industry is essential to achieve the Paris climate goals.A new system to reduce the carbon footprint of steel production is proposed in this article by coupling hydrogen direct reduction of iron ore (H-DRI) and natural gas pyrolysis on the liquid metal surface inside a bubble column reactor. If grid electricity from the EU is used, the emissions would be 435 kgCO\textsubscript{2}/tls without considering methane leakage from the extraction, storage, and transport of natural gas. Solid carbon, produced as a by-product of natural gas decomposition, finds applications in many industrial sectors, including as a replacement for coal in coke ovens. The specific energy consumption (SEC) of the proposed system is approximately 6.3 MWh per ton of liquid steel(tls).It is higher than other competing technologies,3.48 MWh/tls for water electrolysis based DRI, and 4.3-4.5 MWh/tls for natural gas-based DRI and blast furnace-basic oxygen furnace (BF-BOF) respectively. The utilization of large quantities of natural gas, where the carbon remains unused, is the major reason for the high SEC. Preliminary analysis of the system revealed that it has the potential to compete with existing technologies to produce CO\textsubscript{2}free steel, if renewable electricity is used. Further studies on the kinetics of the bubble column reactor, H-DRI shaft furnace, design, and sizing of components, along with the building of industrial prototypes are required to improve the understanding of the system performance.</p>
Liquid metal solves maze
<p>These are supplementary videos for the paper ``Liquid Metal Solves Mazes'. The abstract of the paper is below. </p> <p> </p> <p>A room temperature liquid metal is a metal whose melting point is around room temperature. We use liquid metal gallium due to its non-toxicity. A physical maze is a a connected set of Euclidean domains separated by impassable walls. We demonstrate that a maze filled with sodium hydroxide is solved by a gallium droplet when direct current is applied between start and destination loci. During the maze solving the droplet stays compact due to its large surface tension, navigate along lines of the highest electrical current due its high electrical conductivity, and goes around corners of the maze's corridors due to its high flexibility. The droplet maze solver has a long life-time due to negligible vapour of the liquid gallium.</p>
LiMeS-lab: An integrated laboratory for the development of Liquid-Metal Shield technologies for fusion reactors
<p>The liquid metal shield laboratory (LiMeS-Lab) will provide the infrastructure to develop, test, and compare liquid metal divertor designs for future fusion reactors. The main research topics of LiMeS-lab will be liquid metal interactions with the substrate material of the divertor, the continuous circulation and capillary refilling of the liquid metal during intense plasma heat loading and the retention of plasma particles in the liquid metal. To facilitate the research, four new devices are in development at the Dutch Institute for Fundamental Energy Research and the Eindhoven University of Technology: LiMeS-AM: a custom metal 3D printer based on powder bed fusion; LiMeS-Wetting, a plasma device to study the wetting of liquid metals on various substrates with different surface treatments; LiMeS-PSI, a linear plasma generator specifically adapted to operate continuous liquid metal loops. Special diagnostic protection will also be implemented to perform measurements in long duration shots without being affected by the liquid metal vapor; LiMeS-TDS, a thermal desorption spectroscopy system to characterize deuterium retention in a metal vapor environment. Each of these devices has specific challenges due to the presence and deposition of metal vapors that need to be addressed in order to function. In this paper, an overview of LiMeS-Lab will be given and the conceptual designs of the last three devices will be presented.</p>
