Metal-organic frameworks (MOFs) have gained widespread attention due to their modular construction that allows the tuning of properties. Within this vast class compounds, metal carboxylates containing tri- and tetravalent ions been in focus many studies often high thermal chemical stabilities. Cerium has a rich chemistry, which depends strongly on its oxidation state. Ce(iii) exhibits properties typically observed for rare earth elements, while Ce(iv) is mostly known behaviour. In MOF chemistry reflected unique optical catalytic The synthetic parameters Ce(iii)- Ce(iv)-MOFs also differ substantially conditions must be chosen prevent reduction formation latter. Ce(iii)-MOFs are usually reported comprehensive together with those constructed other RE elements normally they isostructural. They exhibit greater structural diversity, larger variety inorganic building units. contrast, synthesis were only recently (2015) established. These lead selectively hexanuclear Ce-O clusters well-known Zr-MOFs therefore very similar isoreticluar found. Hence porosity, few porous described. Some these show flexibility makes them interesting separation processes. For redox most relevant. Thus, intensively discussed catalytic, photocatalytic sensing applications. perspective, synthesis, Ce-MOFs summarized.

The electrochemical reduction of CO2 stores intermittent renewable energy in valuable raw materials, such as chemicals and transportation fuels, while minimizing carbon emissions promoting carbon-neutral cycles. Recent technoeconomic reports suggested economically feasible target products electroreduction the relative influence key performance parameters faradaic efficiency (FE), current density, overpotential practical industrial-scale applications. Furthermore, fundamental factors, available reaction pathways, shared intermediates, competing hydrogen evolution reaction, scaling relations intermediate binding energies, mass transport limitations, should be considered relation to performance. Intensive research efforts have been devoted designing developing advanced electrocatalysts improving mechanistic understanding. More recently, focus was extended catalyst environment, because interfacial region can delicately modulate catalytic activity provide effective solutions challenges that were not fully addressed material development studies. Herein, we discuss importance catalyst-electrolyte interfaces operational based on kinetic equations. extensively review previous studies controlling organic modulators, electrolyte ions, electrode structures, well three-phase boundary at interface. modulates electrocatalytic properties via electronic modification, stabilization, proton delivery regulation, structure reactant concentration control, regulation.

This work discusses the attributes, fabrication methods, and applications of gallium-based liquid metal particles. Gallium-based metals combine metallic fluidic properties at room temperature. Unlike mercury, which is toxic has a finite vapor pressure, gallium possesses low toxicity effectively zero pressure temperature, makes it amenable to many applications. A variety methods produce particles with variable sizes, ranging from nm mm (which upper limit set by capillary length). The nature enables methods-such as microfluidics sonication-that are not possible solid materials. possess several notable including metal-metal oxide (liquid-solid) core-shell structure well ability self-heal, merge, change shape. They also have unusual phase behavior that depends on size no known commercial applications, but they show promise for drug delivery, soft electronics, microfluidics, catalysis, batteries, energy harvesting, composites. Existing challenges future opportunities discussed herein.

Bulk liquid metals have prospective applications as soft and fluid electrical thermal conductors in electronic optical devices, composites, microfluidics, robotics, metallurgy with unique opportunities for processing, chemistry, function. Yet metals' great potential nanotechnology remains its infancy. Although work to date focuses primarily on Ga, Hg, their alloys, expand the field, we define "liquid metals" alloys melting points (mp) up 330 °C, readily accessible processable even using household kitchen appliances. Such a definition encompasses family of metals-including majority post-transition Zn group elements (excluding itself)-with remarkable versatility physics, engineering. These can create metallic compounds different morphologies, compositions, properties, thereby enabling control over nanoscale phenomena. In addition, presence ionic "pools" within bulk metals, well deviation from classical surfaces provides gaining new capabilities nanotechnology.

Gallium is a metal that literally melts in your hand. It has low toxicity, near-zero vapor pressure, and viscosity similar to water. Despite possessing surface tension larger than any other liquid (near room temperature), gallium can form nonspherical shapes due the thin, solid native oxide skin forms rapidly oxygen.
