For a reliable prediction of CO2 loading in metal−organic (MOFs) and zeolitic-imidazolate frameworks (ZIFs) by molecular simulation, accurate description of the van der Waals (vdW) and Coulomb interactions is undoubtedly the most critical component. However, there have been some strong recent indications that the use of generic force fields (FFs) widely used in most current CO2/ MOF simulations...

Heat transfer via acoustic waves, known as adiabatic thermalization or the piston effect, was previously studied in enclosures under microgravity and terrestrial conditions with carbon dioxide (CO2). Here we report on importance of effect flow boiling a microchannel. It is shown that because large density variations, asymptotical behavior specific heats ratio, enhances heat near critical condit...

Experimentally observed density profile of CO2 laser-produced Sn plasma was compared with that predicted by one dimensional hydrodynamic radiation numerical code. Experimental data showed a much smaller corona and a much shorter shift distance of the critical density from the initial target surface as compared with those predicted by an isothermal model and the numerical simulation. The possibl...

[1] Estimates of fossil fuel CO2 are a critical component in atmospheric CO2 inversions. Rather than solving for this portion of the atmospheric CO2 budget, inversions typically include estimates of fossil fuel CO2 as a known quantity. However, this assumption may not be appropriate, particularly as inversions continue to solve for fluxes at reduced space and timescales. In this study, two diff...

Due to its distinct capability to improve the efficiency of shale gas production, supercritical carbon dioxide (SC-CO2) fracturing has attracted increased attention in recent years. Heat transfer occurs in the transportation and fracture processes. To better predict and understand the heat transfer of SC-CO2 near the critical region, numerical simulations focusing on a vertical flow pipe were p...

In the title compound, [Co(C8H5O4)(C9H6N7)] n , the divalent CoII atom is six-coordinated to three N atoms from two symmetrical 5-(pyridin-4-yl)-1H,2'H-3,3'-bi[1,2,4-triazole] (H2pyttz) ligands and three O atoms from three symmetrical 3-carb-oxy-benzoate (Hbdic) ligands, leading to a distorted {CoN3O3} octa-hedral coordination environment. Two CoII cations are linked by four bridging carboxyl-a...

Rising CO2 levels in the oceans are predicted to have serious consequences for many marine taxa. Recent studies suggest that non-genetic parental effects may reduce the impact of high CO2 on the growth, survival and routine metabolic rate of marine fishes, but whether the parental environment mitigates behavioural and sensory impairment associated with high CO2 remains unknown. Here, we tested ...

The utilization of carbon dioxide (CO2) as a source of carbon in synthetic chemistry has been a practice exploited at the industrial level since the second half of the 19th century for the synthesis of urea [1a] and salicylic acid [1b, c]. CO2 has also long been used for making inorganic carbonates and pigments. A renewed interest in the industrial utilization of CO2 as a source of carbon arose...
