Exploring the thermophysical properties of natural deep eutectic solvents for gas capture applications: a comprehensive review

引用

Green Chemical Engineering 2024年第03期5卷 307-338页

作者： Ahmad Al-bodour noor Alomari Alberto Guti errez Santiago Aparicio Mert Atilhan Department of Chemical and Paper Engineering Western Michigan University Department of Chemistry University of Burgos Faculty of Sciences

With the intensifying challenge of global warming driven largely by anthropogenic activities, effective greenhouse gas capture techniques are critical. This paper focuses on the role of deep eutectic solvents(DES) as promising agents for such capture at the source. We review the key DES-based methods for greenhouse gas capture, drawing conclusions from a thorough analysis of the existing literature. In particular, we examine the effect of DES structure on gas solubilities and explore the mechanism of gas solubility in DES through molecular simulation. We present a synthesis of state-of-the-art results in this area, assessing the potential of DES as an alternative to current industrial gas capture methods. Furthermore, we propose future research directions for the design of novel DES tailored to more specific applications.

钒钛磁铁矿是以铁、钒、钛为主的多金属元素共生的复合矿，在世界分布不均衡。中国是该矿石的主要产出国之一，分布在5个主要矿带。钒钛铁尾矿是钒钛磁铁矿选矿过程中产生的固体工业废弃物，是一种多金属伴生的铁尾矿。该尾矿在中国的堆存量巨大，富含很多有用化学组分，也被称为人工矿床。该尾矿以硅酸盐为主，主要化学成分是二氧化硅、三氧化二铝、氧化钙和氧化铁等，主要矿物是脉石矿物。国内外学者对其在绿色建筑材料综合利用方面做了很多有益探索，但总体来看，这些研究更多停留在实验室里。主要原因是①不同尾矿库甚至同一尾矿库的钒钛铁尾矿理化性能可能有较大差异，尾矿原料的稳定性不足；②受尾矿原料不稳定的理化性能影响，中试结果经常出现较大差异，难以实现规模化利用；③钒钛铁尾矿库大多地处偏僻，运输成本高企，且缺乏高附加值的尾矿产品，规模以上企业因投入大产出小望而生畏。本文综述了钒钛铁尾矿在中国的地域分布和堆存量，重点研究了其化学组成、矿物组成、粒度分布和重金属浸出，分析了作为主要原料在绿色建筑材料方面的研究进展，指出了存在问题并展望了发展前景。

We have successfully demonstrated a stable dual-wavelength Q-switched erbium-doped fiber laser(EDFL) using a single mode fiber-multimode fiber-single mode fiber(SMF-MMF-SMF) structure-based filter. Using a graphene oxide(GO) saturable absorber(SA) to modulate the cavity loss, passive Q-switching of the dual-wavelength laser is achieved at 1 549.6 nm and 1 558.6 nm. The laser recorded the shortest pulse width of about 2.9 μs, the maximum pulse repetition rate of 65.27 kHz and the maximum average output power of 0.99 mW at pump power of 225.1 mW. The present laser has the maximum pulse energy of 15.17 nJ. A 2 SMF-MMF-SMF structure has been experimentally confirmed to be very promising as a wavelength filter.

Chinese Physics b 2018年第1期27卷 415-423页

Structural, electronic, and optical properties of alloys bexMgl-xX （X = S, Se, Te） in the assortment 0 〈 x 〈 1 were theoretically reported for the first time in zinc-blende （Zb） phase. The calculations were carried out by using full-potential linearized augmented plane wave plus local orbitals （FP-LAPW＋lo） formalism contained by the framework of density functional theory （DFT）. Wu--Cohen （WC） generalized gradient approximation （GGA）, based on optimization energy, has been applied to calculate these theoretical results. In addition, we used becke and Johnson （mbJ-GGA） potential, modified form of GGA functional, to calculate electronic structural properties up to a high precision degree. The alloys were composed with the concentrations x = 0.25, 0.5, and 0.75 in pursuance of ＇special quasi-random structures＇（SQS） approach of Zunger for the restoration of disorder around the observed site of alloys in the first few shells. The structural parameters have been predicted by minimizing the total energy in correspondence of unit cell volume. Our alloys established direct band gap at different concentrations that make their importance in optically active materials. Furthermore, density of states was discussed in terms of the contribution of be and Mg s and chalcogen （S, Se, and Te） s and p states and observed charge density helped us to investigate the bonding nature. by taking into consideration of immense importance in optoelectronics of these materials, the complex dielectric function was calculated for incident photon energy in the range 0--15 eV.
