Abstract

The removal of highly toxic gasses such as SO2 and H2S is important in various industrial and environmental applications. Metal organic frameworks (MOFs) are promising candidates for the capture of toxic gases owing to their favorable properties such as high selectivity, moisture stability, thermostability, acid gas resistance, high sorption capacity, and low-cost regenerability. In this study, we perform first principles density functional theory (DFT) and grand-canonical Monte Carlo (GCMC) simulations to investigate the capture of highly toxic gases, SO2 and H2S, by the recently designed ZTF and MAF-66 MOFs. Our results indicate that ZTF and MAF-66 show good adsorption performances for SO2 and H2S capture. The nature of the interactions between H2S or SO2 and the pore surface cavities was examined at the microscopic level. SO2 is adsorbed on the pore surface through two types of hydrogen bonds, either between O of SO2 with the closest H of the triazole 5-membred ring or between O of SO2 with the hydrogen of the amino group. For H2S inside the pores, the principal interactions between H2S and surface pores are due to a relatively strong hydrogen bonds established between the nitrogens of the organic part of MOFs and H2S. Also, we found that these interactions depend on the orientation of SO2/H2S inside the pores. Moreover, we have studied the influence of the presence of water and CO2 on H2S and SO2 capture by the ZTF MOF. The present GCMC simulations reveal that the addition of H2O molecules at low pressure leads to an enhancement of the H2S adsorption, in agreement with experimental findings. However, the presence of water molecules decreases the adsorption of SO2 irrespective of the pressure used. Besides, SO2 adsorption is increased in the presence of a small number of CO2 molecules, whereas the presence of carbon dioxide in ZTF pores has an unfavorable effect on the capture of H2S.

Abstract

In search for future good adsorbents for CO2 capture, a nitrogen-rich triazole-type Metal–Organic Framework (MOF) is proposed based on the rational design and theoretical molecular simulations. The structure of the proposed MOF, named Zinc Triazolate based Framework (ZTF), is obtained by replacing the amine-organic linker of MAF-66 by a triazole, and its structural parameters are deduced. We used grand-canonical Monte Carlo (GCMC) simulations based on generic classical force fields to correctly predict the adsorption isotherms of CO2 and H2O. For water adsorption in MAF-66 and ZTF, simulations revealed that the strong hydrogen bonding interactions of water with the N atoms of triazole rings of the frameworks are the main driving forces for the high adsorption uptake of water. We also show that the proposed ZTF porous material exhibits exceptional high CO2 uptake capacity at low pressure, better than MAF-66. Moreover, the nature of the interactions between CO2 and the MAF-66 and ZTF surface cavities was examined at the microscopic level. Computations show that the interactions occur at two different sites, consisting of Lewis acid–Lewis base interactions and hydrogen bonding, together with obvious electrostatic interactions. In addition, we investigated the influence of the presence of H2O molecules on the CO2 adsorption on the ZTF MOF. GCMC simulations reveal that the addition of H2O molecules leads to an enhancement of the CO2 adsorption at very low pressures but a reduction of this CO2 adsorption at higher pressures.

13. Infrared spectra and structure of solid phases of sulfur trioxide: possible identification of solid SO3 on Io's surface

Abstract

The possibility of establishing the presence of solid sulfur trioxide (SO3) on the surface of the Jovian satellite Io was explored based on an analysis of the structure and infrared spectral features of different types of solid SO3 taken at temperatures of 20-290 Kelvin. The SO3 types examined included amorphous, high-melting asbestos-like, low-melting needle-like, ice-like and monomeric SO3. A comparison of the results of these analyses with spectrum obtained by the Voyager spacecraft yielded evidence supporting the presence of solid SO3 mixed with crystalline SO2.

Abstract

Spectroscopic ellipsometry is used to analyze edge region of thin single-crystal films of ZnSe at room temperature and the results are compared with those of the bulk samples. Pseudo dielectric function of ZnSe thin films is calculated. Interfacial strains do not affect the optical properties of this thick film.

44. H2O on Io? IR spectra of SO2/H2O mixed ices in the 5000-450 cm−1 region

Author

Dahmani, R. and Khanna, R. K.

Abstract

Laboratory transmission IR spectra of relatively thick films (up to ~500 µm) of mixed H2O and SO2 ices were measured at several temperatures between 10 and 130 K in the range 5000-450 cm-1. In addition to the strong features due to crystalline SO2 the spectra reveal bands at ~3668 cm-1, 3634 cm-1 (with some structure) and 3300 cm-1 which are identified with H2O in SO2 environment. Also, there is no overlap between any of the H2O bands with the 3584 cm-1 band of SO2 at any temperature in the above range. The implication of this result is that H2O, if present on Io, must be far less than 1 part in 105 SO2.

Abstract

Introduction: Among patients with unexplained dyspnea, left ventricular (LV) filling pressures (LVFP) is commonly estimated non-invasively by the E/e' ratio using Doppler echocardiography. However the accuracy of E/e' is controversial. We evaluated the correlation of E/e' ratio with invasively measured LVFP and of change in E/e' (ΔE/e') with change in LVFP. Methods: Supine and upright transthoracic echocardiography was performed in patients with unexplained dyspnea undergoing right heart catheterization. Patients with significant valvular disease and reduced LV ejection fraction (LVEF < 50%) were excluded. Pulmonary artery wedge pressure (PAWP) was used as the invasive indicator of LVFP. The mean of septal and lateral e' velocities was used for the calculation of E/e' ratio. Results: We studied 98 subjects with a mean age of 52 ± 20 years (69% of female gender). The supine E/e' and PAWP were 9.2 ± 3.2 and 12.1 ± 4.9 mmHg (range: 4-27 mmHg) respectively and were modestly correlated (r=0.38; p<0.001). With position change (supine to upright), ΔPAWP was -5.1 ± 4.3 mmHg and ΔE/e' was 0.17 ± 2.6, with no significant association between these two measures (r=0.003; p=0.98). Both E-wave (80 ± 22 to 65 ± 22 cm/s) and mean average e' (10.2 ± 3.6 to 7.3 ± 2.0 cm/s) decreased with the upright position. The ΔPAWP was correlated with ΔE-wave velocity (r=0.33; p=0.01), but not with Δe' (r=0.14; p=0.26). Conclusions: In patients with unexplained dyspnea and a preserved LVEF, E/e' is modestly, though significantly, correlated with PAWP. ΔE/e' is not correlated with ΔPAWP, partially related to the preload sensitivity of e'.
