This paper shows common research activities of the Chemical Engineering team from the Institute of Materials Chemistry of the Faculty of Chemistry in Brno, University of Technology, Czech Republic. The paper is focused on application of simplified mathematical model on the experimental data obtained through the carbon dioxide scrubbing in to the deionized water in the experimental gas scrubber. The MS Excel’s (2007) Solver was used for computing simplified mathematical model of gas absorption under unsteady state. The CO2 used for the experiment was of the food quality. 24.675 liters of the deionized water was used as water quantity batch. Absorbed CO2 was detected with the gas electrode.

16 – 20 May 2021 Edited by: Souad MESDOUR-HAMMADOU University M’hamed Bougara of Boumerdes, Algeria Ali-Nordine LEKLOU University of Nante, France Preface The 2nd International Symposium on Materials Chemistry has taken place in Boumerdes Algeria on 16 – 20 May 2021 in the Virtual Scientific Meeting form The Second Symposium on Materials Chemistry (ISyMC2021) aims to bring international and national researchers to high-level exchange on emerging solutions and technologies in the fields of materials science. This international symposium organized by Chemistry department of the University M’hamed Bougara Boumerdes, aims to encourage exchange between participants on the most recent advances in chemical engineering, chemistry materials science, and energetic materials, etc. Over 951 submissions were submitted to us. These papers have gone through a strict reviewing process performed by our international reviewers. All the submissions were double-blind reviewed, both the reviewers and the authors remaining anonymous. With the hard work from the reviewers, only 230 abstracts were finally accepted. The symposium will cover different topics linked to materials synthesis and characterization, interfacial phenomena, systems and materials optimization and modeling. Leading scientists and researchers will share their recent progress and stimulate discussions on multidisciplinary research activities. These communications were divided into four chapters: 1. Inorganic Materials Chemistry Keywords: concrete and cementitious composites, ceramics matrix and glass, Metals and alloys 2. Organic Materials Chemistry Keywords: polymer matrix composites, nanocomposites, Elastomers and rubber, Paint, varnishes and glues, Resins and solvents... 3. Green Processes Keywords: Wood and paper Ecology, Water treatment, Biomass Valorisation, Sustainable chemistry, Renewable energy, Waste management and recovery, recycling, life cycle analysis and sustainability... 4. Processing and manufacturing technologies Keywords: Experimental techniques standardization, nanotechnologies. ACKNOWLEDGMENTS The editors wish to express their gratitude to all the participants of the International Symposium of Materials Chemistry 2021 and its Proceedings: plenary speakers, invited speakers, contributed paper authors and speakers, members of the organizing committee, and members of the scientific committee. Special thanks to all for bringing valuable expertise to pave the way of research into the future.

A flux damping control strategy was proposed to accelerate the decay of stator flux and restrain stator, rotor current and torque oscillation caused by grid voltage dips. Firstly, this paper analyzes the simplified mathematical model of DFIG during symmetrical voltage dips. Then, the mechanism of flux damping control strategy to restrain stator, rotor current oscillation and increase flux damping was analyzed. The flux damping control strategy can increase the damping of stator side, which accelerates the decay of the stator flux natural component and improve the dynamic LVRT performance of DFIG. The correctness and effectiveness of this method is verified by MATLAB/Simulink simulation results.

In São Paulo State, mainly in rural areas, the utilization of wooden poles is observed for different purposes. In this context, wood in contact with the ground presents faster deterioration, which is generally associated to environmental factors and, especially to the presence of fungi and insects. With the use of mathematical models, the useful life of wooden structures can be predicted by obtaining "climatic indexes" to indicate, comparatively among the areas studied, which have more or less tendency to fungi and insects attacks. In this work, by using climatological data of several cities at São Paulo State, a simplified mathematical model was obtained to measure the aggressiveness of the wood in contact with the soil.

Mathematical model and computer programs have been developed for the analysis of the economic performance of a terrestrial solar power system using heat engines. Various combinations of cycle, collector, engine, storage system, and sink have been studied and the influence of design parameters on power costs examined for both the steady and unsteady state cases. Typical minimum power costs under central Australian conditions for units of 12 kw capacity at current levels of materials and labor costs range from 7 to 47 U. S. cents per kwh, according to the specific design of installation.

In this paper an aquatic device inspired to the fish propulsion is proposed. At the first, the operating principle of the fluidic actuator and its experimental characterization are presented. Then, the results of numerous tests carried out on the integrated tail-actuator device are shown either in terms of thrust exerted or as biomorphism of its kinematics. The tests were run at several driven frequencies with different fins depending on their geometrical dimensions and compliances. On the other hand, a simplified mathematical model of the propulsion system, based on the calculation of the instantaneous tail kinematics and dynamics by means of a numerical procedure, is proposed with the aim of simulating performances either in terms of thrust exerted or kinematics behavior. Finally a discussion about the results obtained and a comparison between experimental and numerical data are presented.
