Arithmetic Billiards
Authors: Perucca Antonella , De Sousa Joe Reguengo , Tronto Sebastiano
Published: June 2022

Arithmetic billiards show a nice interplay between arithmetics and geometry. The billiard table is a rectangle with integer side lengths. A pointwise ball moves with constant speed along segments making a 45° angle with the sides and bounces on these. In the classical setting, the ball is shooted from a corner and lands in a corner. We allow the ball to start at any point with integer distances from the sides: either the ball lands in a corner or the trajectory is periodic. The length of the path and of certain segments in the path are precisely (up to the factor √2 or 2√2) the least common multiple and the greatest common divisor of the side lengths.
Tourism and Business Cycles: Does the Relationship Fade Away?
Authors: Kožić Ivan , Arčabić Vladimir , Sever Ivan
Published: June 2022

For a long time, tourism has been considered a social, economic and environmental phenomenon that provides products and services whose consumption is supposed to surge in periods of economic growth and wane in periods of slowdown, thereby acting procyclical. To examine this hypothesis, we have explored the exact behavior of tourism activity before and after the last big economic crisis – the Great Recession 2008 followed by the European Sovereign Debt Crisis. We have applied a methodology of business cycle analysis to investigate the relationship between the cyclical components of GDP and tourism nights spent by the residents of 23 EU member states in the 1996-2018 period. We report an important structural change in the relationship between tourism and business cycles. The relationship became apparently weaker over time and finally became insignificant after the end of the crisis, suggesting a smooth structural change. Our findings suggest uncertainty as to how tourism activity would restore its usual dynamics following the end of the current COVID-19 pandemic recession.
Dividend Policies in Volatile Transitioning Markets
Authors: Dodig Ante , Dzidic Ante
Published: June 2022

This paper examines the implicit impact of an individual company financial parameters on dividends payments. The empirical research is conducted within the environment that cross-examines fifteen European transition economies with shared traits of frontier to emerging capital markets development stage and exposure to exogenic global volatility from 2007/8 and Covid-19 economic crises spilling over at magnitude. The purpose of this paper is to test whether companies establish stable dividend policy. Dividends payments are sensitive to earnings and hence adjust imminently. The reason stems from uncertainty on future financial performance and on investor protection. Results yield negative link between solvency and dividends based on the fact that the weaker solvency position decreases the priority of dividends likelihood. Comparably dividends are less desirable if competing with company growth opportunities although investors are less willing to wait for future profits. Altogether transitioning markets are less responsive and structurally feature fewer corporate events.
Influence of the Risk-Based Approach on the Development of the Management of Organizations
Authors: Avdiiskii Vladimir I. , Bezdenezhnykh Vyacheslav M. , Yartseva Nadezhda M.
Published: June 2022

The current state, processes and development trends of national and world economic systems require the development of fundamentally new theoretical economic models adequate to the market, reflecting real changes in the world in the near future and in the long term. The purpose of this study was to find the right risk management tools. For this, cases were analysed in which various methods of managing the socio-economic sphere were used. Myths and stereotypes about the behaviour of people in this area were identified. The authors emphasized that macro-indicators of the state of economic systems are not canceled and are used in existing calculation models, but their predicted “strength” should be supplemented by a new model analysis based on a risk-based approach, taking into account the distinguished trend of assessing the current economic development.
Aspects of receptions of inogenic cultural-religious elements in complex approach to research
Authors: Efimov Denis Aleksandrovich
Published: June 2022

This article discusses foundations and particularities of the complex approach to researches of processes and phenomena of reception of inogenetic cultural and religious elements. Based on the conception of "comprehending questioning", which, according to Martin Heidegger, is a "ground" for understanding, the author builds a methodologic scheme of the complex approach, which serves to provide a sufficient heuristical minimum in perception of referred subject of research by searching for the answers to the basic issues of scientific philosophical interest. Emphasizing the role of the subject as an efficient cause in processes of cultural-religious syncretism the author focuses on importance of research of his intentions which is expressed verbally, graphically or actively (passively). This task necessitates to differentiate exterior and interior aspects of process or phenomenon being studied. Representing a subjective world as an original place for implementation of syncretization the author gives reasons for expediency of the research of worldview paradigms and dominating idea of subject of reception using not only motivational-targeted analysis but also existential one. A complex research of subject's world relationship, his ontological, epistemological, axiological and praxeological affirmations and social, economic, political and cultural environment enhances the understanding of exogenous and endogenous factors which develop his extrinsic and intrinsic motivation. Based on the interpretation of cultural (religious) norms, principles and imperatives, various degrees of subjects' readiness to accomplish or maintain receptions of inogenic elements allow to identify an analytical category of subjective "bounds of inclusivity" and make it possible to develop three-part classification of receptions, highlighting its separational, alternation and fusional types. Taking into consideration that receptions often operate as no final goal but as an implementer of more extensive plans of achieving one or another goal, the author also offers to distinguish strategy and tactics of receptions. Therefore, a process of reception is presenting as consisting of a range of aspects or steps, the consideration of which constitutes the content of suggested methodological "algorithm" for researching the processes and phenomena of reception of inogenic cultural or religious elements within the framework of the complex approach to research.
The discreteness of historical consciousness and its influence on the process of spiritual and intellectual formation of personality
Authors: Merzlyakova Irina Leonidovna
Published: June 2022

The purpose of the study is to reveal the relationship between the discreteness of historical consciousness and the processes of spiritual and intellectual development of the individual; to offer his vision of what the discreteness of historical consciousness is and to determine the degree of its influence on the process of spiritual and intellectual formation of the individual. The article focuses on the fact that the discreteness of historical consciousness has a destructive effect on public consciousness and its forms. The degree of discreteness of historical consciousness and the level of spiritual and intellectual development of the individual are interdependent and have a mutual influence on each other. As a result of the conducted research, it was revealed that the discrete historical consciousness is a fragmented "torn" historical consciousness, which poses a threat to the spiritual and intellectual formation of the individual.

Power Flow Control using Phase Shift Transformers
Authors: AL-Rawi Mohammed A. , Mostafa Mohamed O.
Published: June 2022

The present paper examines and tests an alternative method to control and redirect electric power flow through certain paths (transmission lines). The control and redirecting of power flow is achieved through the use of phase shift transformers PSTs. An algorithm is presented which searches for a proper phase shift angle introduced by a PST at any given location. The proposed method is based on modelling the PST and the power system employing Newton-Raphson load flow approach. Finally, the installation of series of PSTs on the interconnected power systems aims at mitigating uncontrolled parallel flows and unbalanced sharing of power among transmission lines.  The obtained results showed the effectiveness of the proposed method in sharing and controlling the electrical power flow among different interties of the 5-bus network on which the study applied.

Authors: Al-Shakarchi Yousif J. , Al-Busoda Bushra S. , Al-Taie Abbas J.
Published: June 2022

This paper contains the results of CBR tests that performed on compacted samples of real dune sand (cohesionless sand grains) and pseudo dune sand which is a mixture of sand sized aggregate of clay and silt. The effect of compaction and soaking on the bearing values are included in this research. The results indicated that the compacted real dune sands have high strength and low sensitivity to soaking. The 5 mm penetration of CBR of this soil is higher than that of 2.5 mm. On the other hand, the loss of strength due to soaking can be quite considerable in compacted pseudo dune sands. The CBR values obtained at 2.5 mm and 5 mm penetration are approximately equal in pseudo dune sands.
Optimal Design of Round Bottomed Triangle Channels
Authors: Hameed Ayman T.
Published: June 2022

In optimal design concept, the geometric dimensions of a channel cross-section are determined in a manner to minimize the total construction costs. The Direct search optimization method by using MATALAB is used to solve the resulting channel optimization models for a specified flow rate, roughness coefficient and longitudinal slope. The developed optimization models are applied to design the round bottomed triangle channel and trapezoidal channels to convey a given design flow considering various design scenarios However, it also can be extended to other shapes of channels. This method optimizes the total construction cost by minimizing the cross-sectional area and wetted perimeter per unit length of the channel. In the present study, it is shown that for all values of side slope, the total construction cost in the round bottomed triangle cross-section are less than those of trapezoidal cross-section for the same values of discharge. This indicates that less excavation and a lining are involved and therefore implies that the round bottomed triangle cross-section is more economical than trapezoidal cross-section.

Features of Argentina's diplomatic activity in the XIX – XXI centuries (based on the materials of the Digital Library of Treaties of the Ministry of Foreign Affairs of Argentina)
Authors: Demidov Aleksei
Published: June 2022

The object of the study is the foreign policy of Argentina. The subject of the study is the diplomatic activity of Buenos Aires, expressed in the conclusion of bilateral agreements. The purpose of the article is to build a picture of the development of Argentina's foreign policy based on a quantitative analysis of more than eight thousand documents contained in the Digital Library of Treaties (Biblioteca Digital de Tratados) on the web portal of the Ministry of Foreign Affairs of Argentina. The author examines in detail such aspects of the topic as the general dynamics of Argentine diplomatic activity and the change of priorities in contacts with individual states and regions. Special attention is paid to the comparative dynamics of Argentina's relations with the United States, Russia, China and leading European countries in the period from 1983 to the present. The scientific novelty lies in the fact that the study of this array of documents in their entirety has not yet been conducted by domestic scientists. The article uses general scientific methods of cognition, as well as statistical analysis. The aforementioned library of treaties was used as sources, as well as the works of Argentine and domestic researchers devoted to various aspects of the subject under consideration. As a result of statistical analysis of the collection of treaties, the peculiarities of Argentina's diplomatic activity at different stages of the evolution of its foreign policy were revealed, presented in the form of diagrams and graphs. The main conclusions can be noted, firstly, a sharp increase in diplomatic activity in general and especially outside the region in the period after 1946; a tendency to increase the importance of Russia, China and Asian countries in the period after 1983; while maintaining the priority of relations with European countries under all presidents except K. Fernandez.
WILL THE IMPLEMENTATION OF THE DIRECTIVE ON RESTRUCTURING AND INSOLVENCY HELP THE RECOVERY OF THE CROATIAN MARKETS AND STRENGTH THE ABILITY OF THE DEBTORS TO RESPOND TO NEW CHALLENGES?
Authors: Bodul Dejan
Published: June 2022

It must be pointed out that the issue of bankruptcy proceedings in countries with a long market tradition is a dynamic area where new solutions are sought that will follow the trend of change in the international economy. The European Union, which in 2019 adopted the Restructuring and Insolvency Directive, is also making an exceptional contribution to this issue. With the adoption of the Directive, the European Union has joined the general trend of deviation from traditional, formal bankruptcy proceedings by opening a wide area to private regulation, with all the associated opportunities and risks. From the current point of view of Croatian law, the Directive does not provide “revolutionary” solutions, especially in terms of preventive restructuring, given that Croatian rules on prebankruptcy proceedings are essentially in line with the solutions contained in the Directive. Therefore, the subject of the analysis are valid norms as well as those from the Final Proposal of the Bankruptcy Law from 2022 (February 2022) related to collective legal protection in (pre) bankruptcy proceedings, having in mind the possible consequences of incomplete and inadequate regulation on the rights and interests of participants. The analysis starts from the fact that the issue of legal protection is regulated by each state independently and that such autonomy of member states is limited by EU rules. Therefore, in addition to the legal analysis of legal protection, as it is according to the existing (valid) legal framework (de lege lata), this paper also includes the question of what such protection should be in view of the requirements of European law (de lege ferenda). A limiting factor in the context of this analysis is the lack of well-established judicial practice, given that the implementation of new legislation is in process of public debate. Therefore, the analysis is not based on practical problems, but on detecting possible problems that could cause difficulties in practical implementation of (pre)bankruptcy proceedings.
LEGAL ASPECTS OF THE INTRODUCTION OF THE EURO AS THE OFFICIAL CURRENCY IN THE REPUBLIC OF CROATIA
Authors: Jerković Emina
Published: June 2022

The 1992 Maastricht Treaty defined the conditions for the introduction of the euro as a common currency in the European Union. These are macroeconomic indicators that measure the level of nominal convergence achieved and thus the state’s readiness to participate in monetary union. These conditions (convergence criteria) relate to price stability, stability and sustainability of public finances, which includes budget deficits and public debt, exchange rate stability and convergence of long-term interest rates. In addition to nominal convergence, the degree of legal convergence is also assessed - the provisions of national legislation relating to the independence of the central bank, the ban on monetary financing and preferential access to state financing, and integration into the European System of Central Banks are assessed. Among the member states that have not yet adopted the euro, only the Republic of Croatia is fully harmonized in this regard. On July 10, 2020, the Croatian kuna was included in the European Exchange Rate Mechanism (ERM II). Accessing the ERM II mechanism is often referred to as the euro waiting room. Despite the fact that the pandemic caused by the COVID-19 virus has not abated, the Republic of Croatia has not stopped its efforts to become a full member of the euro area. The paper will present the benefits of the introduction of the euro, but also the inevitable costs incurred during the conversion process. As the pandemic has not slowed down the conversion process and the moment of conversion is approaching, on the other hand, there are conflicting views on the introduction of the euro as the official currency, which are trying to be implemented through a referendum. The paper will discuss the legal aspects of Croatia’s accession to the euro area and what measures are envisaged when exchanging the Croatian kuna for the euro, especially from the aspect of consumer protection, given the fact that Croatia has one of the highest euroization rates of all non-euro area EU member states.
REGULATORY SANDBOXES AND EXPERIMENTATION CLAUSES: AN ATTEMPT TO MAKE THE (CROATIAN) LEGAL SYSTEM MORE ENTREPRENEURIAL
Authors: Štefanek Štefan
Published: June 2022

There is a growing need to develop a suitable regulatory framework for innovative business models. Entrepreneurs who seek to explore new opportunities, test out new technologies and offer new services or products are constrained by the existing legal framework, which in most cases does not allow any experimentation and requires the implementation of strict rules. The EU Council Conclusions 13026/20 of 16 November 2020 on Regulatory Sandboxes and Experimentation Clauses highlight that better regulation is one of the key drivers of sustainable, inclusive growth, fosters innovation, digitalisation, and job creation, increases transparency and ensures public support for EU legislation. This paper explores the design of regulatory sandboxes and the distinctions of experimentation clauses. The starting hypothesis is that innovative business is often unrecognised by the legal system. The second hypothesis is that legal requirements and public interest in diligent entrepreneurial behaviour and customer protection should not be compromised. The research and analysis have reinforced and proved that both hypotheses are reasonable. The findings impact on the raising of the regulators’, entrepreneurs’, customers’ and any other stakeholders’ awareness of the need for proper application and creation of the law in accordance with current social needs, while preserving the fundamental social values achieved.
NEW APPROACH TO THE EU ENLARGAMENT PROCESS – WHETHER COVID-19 AFFECTED CHAPTER 23 REQUIREMENTS?
Authors: Matić Bošković Marina , Kolaković Bojović Milica
Published: June 2022

The EU enlargement policy requires creation of the new institutional organization, alignment of legal acts, increasing capacities of administration in the candidate countries. In relation to the Western Balkans the conditionality has an increased focus on good governance criteria, particularly maintenance of the rule of law, an independent judiciary, and an efficient public administration. To address raised concerns of the EU accession process in the Western Balkans as a box-ticking exercise, the European Commission in February 2018, adopted the Credible Enlargement Perspective for an Enhanced EU Engagement with the Western Balkans’ strategy, which introduced some renewed policy objective on the future enlargement of the EU including fundamental democratic, rule of law and economic reforms. In March 2020 the Council of the EU officially endorsed Commission proposal for a new enlargement methodology that is based on grouping the negotiation chapters in clusters, based on their interconnection, which requires tangible progress in all chapters merged to a cluster. The above-mentioned introduction of a new methodology and the decisions of the WesternBalkans candidate countries to apply it, correspond in time with the ongoing Europe and worldwide struggle to overcome challenges imposed by COVID-19 outbreak. The response to the pandemic influenced on the functioning of judiciary across the world and the rule of law in general. To respond to pandemic EU members states accepted new standards in relation to judiciary which tend to be threat or suspension for fundamental rights protection and right to fair trial. Outbreak of COVID-19 revealed new trends in rule of law like limited access to the lawyer in criminal cases, use of IT tools for trials, and cancelation or limitation of public hearings. The scope and modalities of such rule of law exemptions differ across the EU member states. Introduced measures and responses shed a completely new light on the issues of relevant standards in the accession process and modality to be addressed and implemented in the candidate countries. Finally, this also triggers the issue of evaluation and assessment of the reform achievements in candidate countries by EC when measuring the progress. In the analysis of the abovementioned issues the authors assessed whether derogation of the well-established rule of law principles influenced on EU accession requirements towards candidate countries and whether they temporary changed understanding and implementation of the fundamental rights or made permanent transformations in understanding of rule of law requirements.
FACING REALITY: A NEED TO CHANGE THE LEGAL FRAMEWORK OF THE EU PUBLIC HEALTH POLICY AND THE INFLUENCE OF THE PANDEMIC OF COVID-19 ON THE PERCEPTION OF IDENTITY AND THE ROLE OF THE EU
Authors: Gajić Aleksandar V.
Published: June 2022

The main aim of this article is to highlight two interconnected issues raised in the context of the COVID-19 pandemic. The first one concerns a need to change the EU Health Policy legal framework, particularly the founding treaties (TEU and TFEU), while the second one relates to the issue of the very perception of the identity of the European Union. The possible adequate solution for the situation created by the unprecedented nature of the COVID-19 pandemic and unprecedented measures that followed, was to proclaim state of emergency, which was largely avoided. It seems that it should be considered whether there is a need for amendments of the European Union founding treaties and/or the Charter on Fundamental Rights by providing the possibility of the state of emergency proclamation in the case of “the threats of the life” of the EU. The European Union is not entrusted with the competencies, powers, and responsibilities in health matters such as a pandemic, however founding treaties, functioning institutions as well as procedures seem sufficient for an effective response to health crises such as the one caused by the COVID-19 pandemic. However, having in mind experience with the COVID-19 pandemic it seems that there is a need to strengthen the EU legal framework concerning the issues of pandemic and similar threats, not by altering the nature of the EU competence regarding health issues, but by identifying the threats such as pandemic in the founding treaties that should contain basic regulations concerning European Centre for Disease Prevention and Control. In that manner the efficient response would be in a form of an institutionalized mechanism at the core of the European Union instead of being fully dependent on the variable political will. At the same time there is an urgent need to identify those Health Policy issues that should be an adequate subject of judicial scrutiny. The COVID-19 pandemic also proved that Member States and the European Union should be more realistic regarding the perception of the role and identity of the European Union. The author argues that the identity of the European Union is blurred with a variety of considerations and that its content and features should be more determined, not only in academic literature but also in political practice, especially when it comes to the issue of self-determination of the European Union. The world is not the same as it was before the pandemic, and it seems that the European Union, in order to be prepared to face new challenges, must build its identity in realistic parameters and act in one voice “if it wants to make itself heard and play its proper rôle in the world”, as it was declared in the 1973 Declaration on the European Identity.

Although polycrystalline solid electrolytes are central to the utilization of solid- state batteries with lithium metal anodes, lithium dendrite formation and reduced Li-ion conductivity at their grain boundaries remain primary concerns. Given that experimental studies on polycrystalline materials are notoriously difficult to perform and interpret, computational techniques are invaluable for providing insight at the atomic scale. Here, we carry out first-principles calculations on representative grain boundaries in three important Li-based solid electrolyte families, namely, an anti-perovskite oxide, Li3OCl, a thiophosphate, Li3PS4, and a halide, Li3InCl6, to demonstrate the significantly different impacts that grain boundaries have on their electronic structure, ion conductivity and correlated ion transport. Our results show that even when grain boundaries do not significantly impact ionic conductivity, they can still strongly perturb the electronic structure and contribute to undesirable electrical conductivity and potential lithium dendrite propagation. We also illustrate, for the first time, how cor- related motion, including the so-called paddle-wheel mechanism, which has so far only been considered for the bulk, can vary substantially at grain boundaries. Our findings reveal the dramatically different behaviour of solid electrolytes at the grain boundary compared to the bulk and its potential consequences and benefits for the design of solid-state batteries.
An Orbital Weak Interaction Theory of Catalytic Activity in Ammonia Synthesis and Hydrogen Evolution Reaction
Authors: Sun Youyi
Published: June 2022

In the research for a quantitative correlation between catalytic activity and the property of various catalysts, the electronic configuration, at each catalytic atom in solid-state materials, is considered as an important factor. Comparing the reported experimental results of various pure metal catalysts for Ammonia Synthesis (AS) and Hydrogen Evolution Reaction 10 (HER), we find that the elements having suitable electronegativity and sufficient accessible half-filled orbitals are most positive for catalytic activity. It is, therefore, proposed that the half-filled orbitals interaction between reactant species and the catalytic active atom plays a decisive role in catalytic activity. The theoretical significance of this discrimination of the orbitals’ interaction in relation to the catalytic behaviors is discussed.
Optical tactile sensor using scattering inside sol–gel-derived flexible macroporous monoliths
Authors: Hayase Gen
Published: June 2022

Tactile sensors are an essential technology for robots, and various types have been developed. This paper reports on a new optical tactile sensor based on multiple scattering in a porous material with a viscoelastic phase-separated structure fabricated by a sol-gel method. When a macroporous silicone monolith with a few micrometer diameter skeletons was compressed, the diffuse light intensity near the light source was reduced due to Mie multiple scattering. A simple tactile sensor using a macroporous monolith and a photo reflector was fabricated based on this finding. The skeleton diameter was an important factor for the sensor. In the case of macroporous silicones, the voltage-strain curve showed an almost hysteresis-free clear response. However, the response of macroporous polymethylmethacrylate monolith with a smaller skeleton diameter was weak due to low Mie scattering intensity. Using cell structure materials with a scale much larger than the optical wavelength, a decrease in light intensity with compression was not observed. Sensors using sol-gel-derived flexible macroporous monoliths could provide features such as thinness and improved surface tactility.

Redox flow batteries (RFBs) are a promising electrochemical storage solution for power sector decarbonization, particularly emerging long-duration needs. While the battery architecture can host many different redox chemistries, the vanadium RFB (VRFB) represents the current state-of-the-art due to its favorable combination of performance and longevity. However, the relatively high and volatile price of vanadium has hindered VRFB financing and deployment opportunities. Here we evaluate the vanadium supply chain to understand how it enables or constrains VRFB advancement and assess opportunities for accelerated growth. We find that – while vanadium may not be scarce – its abundance is confounded by highly concentrated production coupled with the disperse nature of sources suitable for potential supply increase. These factors challenge rapid growth, limiting deployment rate and magnitude. We estimate gigawatt-hour deployment scales are feasible over the next decade, which would represent marked expansion of the RFB industry and drive down system costs substantially, though this would require growth rates above historical averages. Accordingly, we review opportunities to accelerate supply chain growth and economic strategies to stabilize the market. Finally, we posit terawatt-hour deployment scales will be challenged by vanadium market conditions and, even, resource availability, motivating the continued efforts developing next-generation RFB chemistries.

An alternative approach for obtaining accurate vertical ionization potentials (VIPs) and electron affinities (VEAs) via coupled-cluster excitation energy calculations is proposed. The concept allows a coherent handling of all ionic states, including ionizations from lower valence orbitals and attachments to higher-lying virtual ones. The use of existing, widespread quantum chemistry codes with minimal modifications makes the application of well-established wave function models possible, in full consistency with the treatment of charge transfer excitations. Among them, the spin-component scaled forms of the CC2 and ADC(2) methods are potent approaches, especially the scaled opposite-spin variants whose efficient implementations allow the handling of larger systems. The performance of several models is evaluated via benchmark calculations on various sets from previous works, containing small and medium-sized systems, including nucleobases. It is shown that with the most effective scaled approximate methods the accuracy of EOM-CCSD is achievable at a fraction of the computational cost, also outperforming many common electron propagator approaches.
Diffusion of Water Confined between Graphene Oxide Layers: Implications for Membrane Filtration
Authors: Meshhal Moyassar , Kuehn Oliver
Published: June 2022

Among the carbon-based two-dimensional materials, graphene oxide (GO) has been attracting a growing interest due to its capability to be utilized in the field of water remediation. Therefore, an atomistic understanding of the transport properties of water in layered GO is pivotal for the development of novel GO membranes. Surprisingly, the very issue of the two-dimensional self-diffusion of water confined between two GO sheets appears to be controversial and simulations showing either a slow-down or no effect have been reported. In any case the formation of Hydrogen bonds, i.e. among the confined water and between water and the GO functional groups, was identified to control diffusion. However, results of molecular dynamics simulations heavily depend on the used forces. Density functional theory and empirical force fields are on opposite when it comes to accuracy and numerical costs. As a compromise in the present study we performed molecular dynamics simulations using a density functional theory-based tight method (xTB) to investigate the diffusion of water confined between GO sheets. Specifically, we considered six GO/water models, differing in the ordering of epoxide and hydroxyl groups as well as in the thickness of the water layer. For these models, having GO inter-layer distances between 8 and 12 \AA{} we find a reduction of the diffusion coefficient by a factor in between two and three as compared with bulk water. One possible origin of this effect is the temporary trapping of water within Hydrogen-bonded water bridges between the GO sheets. The proposed mechanism should be taken into account when developing, for instance, GO membranes for water remediation or applications in the field of selective transport in separation membranes.
