“…The simulated nanocrystalline size obtained using the multiscale velocity triangle theory varied from 32 to 89 nm, consistent with the results obtained from the XRD patterns. These results also have the same order of magnitude reported in the literature. − Simultaneously, the crystal size is consistent with the deduced results by SEM as shown in Figure and the velocity transformation shown in eq . For CO 2 desorption in the TECC process, the CuMEA complex intensifies the CO 2 desorption.…”

Electrodes and transfer processes are the key to thermal electrochemical CO2 capture. The lifetime of electrodes and capture performance are significantly affected by the microscale (micro- and nanocrystalline) structural change and transfer mechanism. Experimental and time-consuming theoretical studies are expensive, and it is difficult to understand microscale structural changes and transfer mechanism due to a lack of relevant unified knowledge. Thus, a time-saving multiscale velocity unified theory was developed by synergizing the molecular motion and matter movement. The theory well predicts the microscale structural change in electrodes and quantifies the chemical reaction and heat and mass transfer under normal and superhigh/superlow operating conditions. A porous electrode and U-shaped multilayer electrode were designed, and the lifetime of electrodes increased by 30%. The U-shaped multilayer electrode self-repairs its microscale structure, and its mass transfer coefficient increased by 15%. The theory simplifies the computational fluid dynamics and molecular dynamics simulation.

The coordination properties of 3,4-dihydroxycyclobut-3-ene-1,2-dionate, C 4 O 4 2− (squarate dianion) ligand, in relation to its ability to form different bonding bridging modes with metal ions are explored. These bonding modes led to the formation of a wide range of polynuclear and polymeric coordination compounds. The magnetic properties of the structurally characterized bridged-squarato compounds with CuĲII) and NiĲII) are reported as a function of the structural parameters of the complexes.

Fac‐bis(ethanolamine)orotatonickel(II), [Ni(HOr)(ea)2] and mer‐bis(ethanolamine)orotatocopper(II) dihydrate, [Cu(HOr)(ea)2]· 2H2O were synthesized and characterized by elemental analysis, FT‐IR, UV‐Vis Spectroscopy and thermal analysis. In addition, their solid‐state structures were determined by single crystal X‐ray diffraction studies. Both the fac‐[Ni(HOr)(ea)2] (1) and mer‐[Cu(HOr)(ea)2]·2H2O (2) complexes are isomorphous and crystallize in the triclinic space group $P {\bar 1}$. The Ni2+ and Cu2+ ions are coordinated by two neutral ea ligands and one orotate dianion in a distorted octahedral fashion. The ea ligand acts as a bidentate donor through the amine N and hydroxyl O atoms, while orotate dianion is coordinated through deprotonated N3 pyrimidine atom and carboxylate oxygen atom as a bidentate ligand. Thermal decompositions of the complexes are studied in over the range 20–600 °C on heating in a static air atmosphere.
