“…Those clouds of points are represented regardless of solvent concentration, gas feed concentration or the system fluid dynamics − It can be observed that, in each type of the membrane, the mass transfer coefficient increases with the increase of the temperature, regardless of other operational conditions. Among all the studies, de Montigny et al have achieved the highest mass transfer coefficient. They have studied two types of the membranes: polypropylene (PP) and polytetrafluoroethylene (PTFE) for CO 2 capture.…”

Capture and utilization or storage of CO2 have been considered as the primary options to reduce the impact on the climate caused by CO2 emissions. Several technological approaches have been proposed depending on the point of actuation (precombustion, postcombustion, or oxyfuel combustion), but absorption processes are still the most extended solution implemented in the industry. Alkanolamines are typical solvents used for CO2 capture, even though they have a noticeable negative impact on the environment. Amino acids and their salts have been appointed as alternative solvents since their functional group is similar to that of alkanolamines but presenting better properties. In addition, they show very good performance in CO2 capture. This manuscript reviews the state of the art of the use of amino acids in CO2 capture and the main technologies involving the application of these solvents.

“…The use of inflatable structures and methods for its structural analysis are also described with reference to expandable lunar habitats [15], and to antennas for small Cubesat satellites [16]. The papers [17] and [18] represent some of the most recent studies on the structural analysis of inflatable structures for space applications. The concepts and experiences presented by these authors in the design and structural modelling of inflatable structures have been taken into account in the work described in this paper.…”

This paper presents a conceptual design of a satellite device to be used for capturing asteroids, based on inflatable structures. The mission requirements, the conceptual design, the methodology for the selection of the best solution, and simulations for the preliminarily structural analysis of the device are described within. Several finite element analyses have been carried out in order to find the best strategy to model flexible materials under internal pressure, and the device structure has been changed accordingly in order to obtain the best trade-off between weight and strength. This paper presents the sizing and the weight breakdown of the satellite inflatable components, which are quite complex to model with regards to the structural simulation. The results obtained seem to confirm the feasibility of such a structure and motivates further studies and experimental tests.

“…Inflatable space structures are useful tools for connecting spacecrafts and payloads for the merits of light weight, small launch volume, and flexible design. Recent years have witnessed a wide applications of the inflatable structures in aerospace engineering, such as antennae, solar arrays, and telescopes [1][2][3][4]. Particularly, for deep space exploration and earth observation, the inflatable space structure is regarded as the most effectiveness and economic way to establish a high-resolution imaging system.…”

The vibration generated by the inflatable structure after deployment has a great impact on the performance of the payloads. In this paper, the influence of the control moment gyroscope (CMG) on the dynamic responses and characteristics of an inflatable space structure is studied, based on the flexible multibody dynamics in combination of the absolute nodal coordinate formulation (ANCF) and the natural coordinate formulation (NCF). Firstly, the ANCF and NCF are used to accurately describe the large deformations and large overall motions of flexible inflatable tubes and rigid satellites, respectively. Afterwards, by using the Lagrange equation, a rigid body dynamic model of the CMG is established in detail, which can be attached to and coupled with any flexible bodies without any assumptions. Then, the orbital dynamic equations of the inflatable space structure coupled with distributed CMGs are obtained by considering the effects of Coriolis force, centrifugal force, and gravity gradient through coordinate transformation. The dynamic characteristics of the inflatable space structure are also analyzed by deriving the eigenvalue problem of a flexible multibody system. Finally, the accuracy of the CMG dynamic model is verified via a classic heavy top example. And several numerical examples are presented to study the influence of the magnitudes and directions of the rotor angular momentum of the CMG on the dynamic responses and characteristics of the inflatable space structure.
