Understanding non-covalent molecular recognition events at biomembrane interfaces is important in biological, medicinal, and materials chemistry research.1 Despite the crucial regulatory roles of anion binding/transport processes at biomembranes, no information is available regarding how strongly anions can bind to naturally occurring or synthetic receptors in lipid bilayer environments compared to their well-established behaviour in solutions.2 To bridge this knowledge gap, we synthesised a flat macrocycle that possesses a record aqueous SO42– affinity among neutral receptors and exploited its unique fluorescence response at interfaces. We show that the determinants of anion binding are extraordinarily different in organic solvents and in lipid bilayers. The high charge density of dihydrogen phosphate and chloride ions prevails in DMSO, however in lipids they fail to bind the macrocycle. Perchlorate and iodide hardly bind in DMSO but show significant affinities for the macrocycle in lipids. Our results demonstrate a surprisingly great advantage of large, charge-diffuse anions to bind to a lipid-embedded synthetic receptor mainly attributed to their higher polarisabilities and deeper penetration into the bilayer, beyond the common knowledge of dehydration energy-governed selectivity. The elucidation of these principles enhances our understanding of biological anion recognition functions in membranes and guides the design of ionophores and molecular machines operating at biomembrane interfaces.

Simplified Mathematical Model

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.

General Organization

<p>Introduction is a significant part-genre of a research article (RA) since it functions to persuade the readership that their research topic has some significance, that there is space for new knowledge around the topic and that the writer can make a contribution to knowledge. Previous studies mainly focused on experienced English L1 and L2 published writers. Masters majoring in Chemical Engineering in China are highly motivated to publish English RAs in international journals due to the requirements for graduation, but to date no work investigates into the disparity between their English RA introductions (ERAIs) and that of high impact SCI journals in terms of generic structure. To fill this gap, drawing on Swales’ CARS model (1990, 2004), this study analyzed the ERAIs written by L1 Chinese masters majoring in chemical engineering and L1 English published writers of the same discipline with a focus on the generic structure. The findings show that the NES published writers employ much more moves than the Chinese student writers, especially Move 1 “establishing a territory” and Move 2 “establishing a niche”. Due to the lack of Move 2, the completeness of the general organization of ERAIs written by the Chinese student writers is much weaker than the NES published writers. From the perspective of the constituent steps, the findings show that the lack of Move 1-Step 3 causes the overall insufficiency of Move 1 in the student writer group (SWG) compared with the published writer group (PWG) and the inadequate Step 1A “indicating a gap” leads to the overall deficiency of Move 2 in SWG. In Move 3, Step 1 is most frequently used in both groups. Although Step 5 and Step 6 are employed in this move but their frequency is low and quite similar to each other in these two groups. The findings have some pedagogical implication on the teaching of writing ERAIs.</p>

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.
