description: Развитие экономики РФ в значительной степени связано с обеспечением конкурентоспособности товаров и услуг, которые она производит. Достигнув высоких конкурентных преимуществ, товаропроизводитель может расширять рынки сбыта, в том числе за пределы РФ. Таким образом, реализация проектов, связанных с развитием международной торговли, экспорта и международной кооперации, имеет большое значение для развития экономики в целом. Активизация международной торговли способствует росту благосостояния и населения, и самих производителей, так как обеспечивается рост доходов предприятий и обеспечение занятости. Авторами проведен анализ отдельных направлений внешнеторговой политики и возможности их воздействия на развитие несырьевого экспорта. В данной статье рассмотрены возможности российских производителей наращивать экспорт с учетом реализации национального проекта «Международная кооперация и экспорт» и входящих в него федеральных и региональных проектов. В статье представлен анализ реализации проектов по развитию экспорта как в целом в стране, так и в отдельном регионе – Кемеровская область – Кузбасс.

description: The Nambu-Jona-Lasinio model is considered with flavor-dependent coupling constants $G_{ij} \left[ ( \barψ λ_i ψ) ( \barψ λ_j ψ)+ ( \barψ iγ_5 λ_i ψ) ( \barψ i γ_5λ_j ψ)\right]$ for $i,j=0,1..N_f^2-1$, and $N_f=3$. A self consistent calculation of quark effective masses and coupling constants is performed making the strange quark effective mass to vary considerably. Quantum mechanical mixings between up, down and strange constituent quarks yields a strangeness content of the light u and d quarks constituent and of the pion. Different types of estimates for the strangeness contribution for the pion mass are provided. Mixing type interactions, $G_{i\neq j}$, induce the light mesons mixings and estimates for the $π^0-η$ and $η-η'$ mixings are provided. The $η-π^0$ mixing is argued to be an indication of the strangeness content of the pion.

description: In this paper, we prove the convexity of trace functionals $$(A,B,C)\mapsto \text{Tr}|B^{p}AC^{q}|^{s},$$ for parameters $(p,q,s)$ that are best possible, where $B$ and $C$ are any $n$-by-$n$ positive definite matrices, and $A$ is any $n$-by-$n$ matrix. We also obtain the monotonicity versions of trace functionals of this type. As applications, we extend some results in \cite{HP12quasi,CFL16some} and resolve a conjecture in \cite{RZ14} in the matrix setting. Other conjectures in \cite{RZ14} will also be discussed. We also show that some related trace functionals are not concave in general. Such concavity results were expected to hold in different problems.

PARIOT: Anti-Repackaging for IoT Firmware Integrity

description: IoT repackaging refers to an attack devoted to tampering with a legitimate firmware package by modifying its content (e.g., injecting some malicious code) and re-distributing it in the wild. In such a scenario, the firmware delivery and update processes play a central role in ensuring firmware integrity. Unfortunately, several existing solutions lack proper integrity verification, exposing firmware to repackaging attacks. If this is not the case, they still require an external trust anchor (e.g., signing keys or secure storage technologies), which could limit their adoption in resource-constrained environments. In addition, state-of-the-art frameworks do not cope with the entire firmware production and delivery process, thereby failing to protect the content generated by the firmware producers through the whole supply chain. To mitigate such a problem, in this paper, we introduce PARIOT, a novel self-protecting scheme for IoT that allows the injection of integrity checks, called anti-tampering (AT) controls, directly into the firmware. The AT controls enable the runtime detection of repackaging attempts without needing external trust anchors or computationally expensive systems. PARIOT can be adopted on top of existing state-of-the-art solutions ensuring the widest compatibility with current IoT ecosystems and update frameworks. Also, we have implemented this scheme into PARIOTIC, a prototype to automatically protect C/C++ IoT firmware. The evaluation phase of 50 real-world firmware samples demonstrated the feasibility of the proposed methodology and its robustness against practical repackaging attacks without altering the firmware behavior or severe overheads.

description: We extend a microscopic theory of polarization and magnetization to include the spin degree of freedom of the electrons, introducing a general spin orbit coupling and Zeeman interaction term in the Hamiltonian. At finite frequencies and including spin, the magnetoelectric polarizability tensor is replaced by two separate tensors, one that relates the polarization \textbf{P} to the magnetic field \textbf{B} and a separate tensor that relates the magnetization \textbf{M} to the electric field \textbf{E}. When combined with other relevant response tensors a third rank tensor that relates the induced current density to gradients in the electric field can be introduced; it is gauge invariant, in a form suitable for numerical calculations, and describes optical activity -- including spin effects -- even in materials that may lack time reversal symmetry.

description: The idea of Verlinde that gravity is an entropic force caused by information changes associated with the positions of material bodies, is used in the present work for the FRW model of the Universe. Using modified Hawking temperature, the Friedmann equations are derived on any horizon. For the validity of the first law of thermodynamics (i.e., Clausius relation) it is found that there is modification of Bekenstein entropy on the horizon. However, using equipartition law of energy, Bekenstein entropy is recovered.

description: We target the problem of automatically synthesizing proofs of semantic equivalence between two programs made of sequences of statements. We represent programs using abstract syntax trees (AST), where a given set of semantics-preserving rewrite rules can be applied on a specific AST pattern to generate a transformed and semantically equivalent program. In our system, two programs are equivalent if there exists a sequence of application of these rewrite rules that leads to rewriting one program into the other. We propose a neural network architecture based on a transformer model to generate proofs of equivalence between program pairs. The system outputs a sequence of rewrites, and the validity of the sequence is simply checked by verifying it can be applied. If no valid sequence is produced by the neural network, the system reports the programs as non-equivalent, ensuring by design no programs may be incorrectly reported as equivalent. Our system is fully implemented for one single grammar which can represent straight-line programs with function calls and multiple types. To efficiently train the system to generate such sequences, we develop an original incremental training technique, named self-supervised sample selection. We extensively study the effectiveness of this novel training approach on proofs of increasing complexity and length. Our system, S4Eq, achieves 97% proof success on a curated dataset of 10,000 pairs of equivalent programs.

description: Event-Shape Engineering (ESE) is a tool that enables some control of the initial geometry in heavy-ion collisions in a similar way as the centrality enables some control of the number of participants. Utilizing ESE, the path length in and out-of plane can be varied while keeping the medium properties (centrality) fixed. In this proceeding it is argued that this provides additional experimental information about jet quenching. Finally, it is suggested that if ESE studies are done in parallel for light and heavy quarks one can determine, in a model independent way, if the path-length dependence of their quenching differs.

Photo-acoustic tomography in a rotating measurement setting

subject: FOS: Mathematics

description: Photo-acoustic tomography (PAT) aims to leverage the photo-acoustic coupling between optical absorption of light sources and ultrasound (US) emission to obtain high contrast reconstructions of optical parameters with the high resolution of sonic waves. Quantitative PAT often involves a two-step procedure: first the map of sonic emission is reconstructed from US boundary measurements; and second optical properties of biological tissues are evaluated. We consider here a practical measurement setting in which such a separation does not apply. We assume that the optical source and an array of ultrasonic transducers are mounted on a rotating frame (in two or three dimensions) so that the light source rotates at the same time as the US measurements are acquired. As a consequence, we no longer have the option to reconstruct a map of sonic emission corresponding to a given optical illumination. We propose here a framework where the two steps are combined into one and an absorption map is directly reconstructed from the available ultrasound measurements.

We discuss the free energy and prominent expectation values. The limit of vanishing temperature is discussed as well.

Subjects: Blockchain, IOT

description: The Internet of Things (IoT) has extended the internet connectivity to reach not just computers and humans, but most of our environment things. The IoT has the potential to connect billions of objects simultaneously which has the impact of improving information sharing needs that result in improving our life. Although the IoT benefits are unlimited, there are many challenges
 facing adopting the IoT in the real world due to its centralized server/client model. For instance, scalability and security issues that arise due to the excessive numbers of IoT objects in the network. The server/client model requires all devices to be connected and authenticated through the server, which creates a single point of failure. Therefore, moving the IoT system into the decentralized path may be the right decision. One of the popular decentralization systems is blockchain. The Blockchain is a powerful technology that decentralizes computation and management processes which can solve many of IoT issues, especially security. This paper provides an overview of the integration of the blockchain with the IoT with highlighting the integration benefits and challenges. The future research directions of blockchain with IoT are also discussed. We conclude that the combination of blockchain and IoT can provide a powerful approach which can significantly pave the way for new business models and distributed applications.

description: In recent synchrotron radiation facilities, the use of short (picosecond) electron bunches is a powerful method for producing giant pulses of Terahertz Coherent Synchrotron Radiation (THz CSR). Here we report on the first direct observation of these pulse shapes with a few picoseconds resolution, and of their dynamics over a long time. We thus confirm in a very direct way the theories predicting an interplay between two physical processes. Below a critical bunch charge, we observe a train of identical THz pulses (a broadband Terahertz comb) stemming from the shortness of the electron bunches. Above this threshold, a large part of the emission is dominated by drifting structures, which appear through spontaneous self-organization. These challenging single-shot THz recordings are made possible by using a recently developed photonic time stretch detector with a high sensitivity. The experiment has been realized at the SOLEIL storage ring.

description: Branch and cut is the dominant paradigm for solving a wide range of mathematical programming problems -- linear or nonlinear -- combining efficient search (via branch and bound) and relaxation-tightening procedures (via cutting planes, or cuts). While there is a wealth of computational experience behind existing cutting strategies, there is simultaneously a relative lack of theoretical explanations for these choices, and for the tradeoffs involved therein. Recent papers have explored abstract models for branching and for comparing cuts with branch and bound. However, to model practice, it is crucial to understand the impact of jointly considering branching and cutting decisions. In this paper, we provide a framework for analyzing how cuts affect the size of branch-and-cut trees, as well as their impact on solution time. Our abstract model captures some of the key characteristics of real-world phenomena in branch-and-cut experiments, regarding whether to generate cuts only at the root or throughout the tree, how many rounds of cuts to add before starting to branch, and why cuts seem to exhibit nonmonotonic effects on the solution process.

description:
Vivianite is a poorly soluble iron (II) phosphate phase found in modern and ancient anoxic soils and sediments. It plays an important role in the biogeochemical cycling of Fe (II) and P and is also a promising P recovery source from waste water. Despite this, the mechanisms and kinetics of vivianite formation are still unknown. Here we present results from a study where we followed the pathway of nucleation and growth of vivianite in solution, starting from aqueous iron (II) and phosphate ions. We aimed to shed light on whether vivianite – like many other sparingly soluble phases – forms via a classical or a non-classical nucleation and growth pathway. To address this, we employed a series of cross-correlated in-situ and ex-situ approaches to followed the time resolved formation reactions using UV-vis spectrophotometry, scanning and transmission electron microscopy, powder X-ray diffraction, infrared spectroscopy, simultaneous thermal gravimetric-differential thermal analyses and synchrotron-based X-ray absorption experiments. These complementary approaches helped us unravel the various stages of nucleation and crystallization of vivianite at high and low supersaturation. Our data indicates that vivianite nucleates via distinct stages in solution and not via a single step, thus following a non-classical nucleation and crystallization pathway. We also demonstrated how one can stabilize and characterize the structure, chemical composition of the intermediate phases and discuss the factors influencing their stability and transformation to the more thermodynamically stable crystalline vivianite.

description: Estimating the 3D structure of the drivable surface and surrounding environment is a crucial task for assisted and autonomous driving. It is commonly solved either by using 3D sensors such as LiDAR or directly predicting the depth of points via deep learning. However, the former is expensive, and the latter lacks the use of geometry information for the scene. In this paper, instead of following existing methodologies, we propose Road Planar Parallax Attention Network (RPANet), a new deep neural network for 3D sensing from monocular image sequences based on planar parallax, which takes full advantage of the omnipresent road plane geometry in driving scenes. RPANet takes a pair of images aligned by the homography of the road plane as input and outputs a $γ$ map (the ratio of height to depth) for 3D reconstruction. The $γ$ map has the potential to construct a two-dimensional transformation between two consecutive frames. It implies planar parallax and can be combined with the road plane serving as a reference to estimate the 3D structure by warping the consecutive frames. Furthermore, we introduce a novel cross-attention module to make the network better perceive the displacements caused by planar parallax. To verify the effectiveness of our method, we sample data from the Waymo Open Dataset and construct annotations related to planar parallax. Comprehensive experiments are conducted on the sampled dataset to demonstrate the 3D reconstruction accuracy of our approach in challenging scenarios.

description: Современная экономика основана на многих фундаментальных науках и направлениях, маркетинг не является исключением в этом отношении. Актуальность вопроса общения всех субъектов рынка друг с другом с экономической выгодой становится еще более очевидной, когда экономические условия не только не стабильны, но и агрессивны, гипертрофированно пластичны, деформированы в разных отраслях и сферах деятельности. Цель статьи – осветить проблему интеграции маркетинговых коммуникаций в сложившихся условиях развития экономических отношений субъектов регионального рынка. Задачи основаны на понимании сути маркетинговой деятельности, важности коммуникации с рынком и формировании современных экономических взаимодействий, адаптированных к новым рыночным условиям. Изучение региональных проблем маркетинговой деятельности и, как следствие, интеграции маркетинговых коммуникаций, посредством мониторинга информации в СМИ и открытых интернет-ресурсах, позволило нам сделать вывод о том, что отказ предприятий Ростовской области и Ростова-на-Дону от интеграции маркетинговых коммуникаций является неэффективным.

description: Dopamine (DA) and its analogues are compounds of interest in polymer science where their properties provide a multitude of applications. However, in elucidating polydopamine structure, there are ambiguities related to the types of bonds, the structure of monomeric units, their ratio, and influence of synthesis parameters. In order to minimize these variables, isotopic labeling presents an optimal alternative. In the diversification and understanding of these polymers, we aim to investigate analogues that by selective isotopic labeling provide possibilities for structure elucidation both of the polymerized analogues as well as polydopamine. In the present paper we report the synthesis of three new dopamine derivatives, labeled *CL ((Z)-3-(3,4-bis(benzyloxy)phenyl)-2-cyano-2-propenamide) and both labeled and unlabeled DL/*DL (2-aminomethyl-3-(3,4-dihydroxyphenyl)propionamide). The labeled *CL and *DL compounds contain selective 13C and 15N labeling in the alkyl chain. For these new compounds, NMR, FT-IR and fluorescence characterization, including by time-resolved laser spectroscopy, are reported.

description: In an attempt to quantify the role of polydispersity in colloidal suspensions, we present an efficient implementation of the renormalized jellium model for a mixture of spherical charged colloids. The different species may have different size, charge and density. Advantage is taken from the fact that the electric potential pertaining to a given species obeys a Poisson's equation that is species independent; only boundary conditions do change from a species to the next. All species are coupled through the renormalized background (jellium) density, that is determined self-consistently. The corresponding predictions are compared to the results of Monte Carlo simulations of binary mixtures, where Coulombic interactions are accounted for exactly, at the primitive model level (structureless solvent with fixed dielectric permittivity). An excellent agreement is found.

description: The present study reports the cymoxanil adsorption efficiency on carboxy-carbon nanotubes (CNT-COOH)/manganese(IV) oxide (MnO2)/iron(II,III) oxide(Fe3O4) nanocomposite. The optimum conditions were determined by studying the influence of pH (2-10), temperature (20-60 °C), initial cymoxanil concentration (7-20 mg L−1), adsorbent dose (0.5-5 g L−1) and contact time (2-30 min) on the adsorption process. The isotherm and kinetic models were used to analyze the experimental data. The Langmuir isotherm model was shown to provide the best fit with a 10.672 mg g−1 maximum adsorption capacity. Also, the cymoxanil adsorption follows the pseudo-second order kinetic model. According to these results, the CNT-COOH/MnO2/Fe3O4 nanocomposite may be used for cymoxanil removal from aqueous solution.

description: Conspiracy theories on social media have been suspected of contributing to mobilization and radicalization. Yet, few studies have examined the prevalence of psychological variables that may serve to motivate normative and non-normative collective action in this material. Drawing from the “social identity model of collective action,” the current study uses a mixed-methods approach to examine the prevalence of collective action cues in conspiracy theory-endorsing social media spaces. Towards this end, I examined four German Facebook groups (Covid-19-Skeptic, Far-Right, Chemtrail, and Political Affairs) during the first months of the Covid-19 pandemic. The results of qualitative content analysis (N = 828 posts), a hierarchical cluster analysis, and the examination of popularity cues showed that: (a) collective action cues were frequent; (b) most posts transmitted alternative views (Cluster 1) or absolutist ideologies (Cluster 2) with few collective action cues—yet, more than one-third of the posts were either mobilizing (Cluster 3) or wrathful (Cluster 4), entailing multiple collective action cues including cues theoretically linked to non-normative action; (c) mobilizing and wrathful posts were more engaging than alternative views and absolutist ideologies; (d) the types of posts and levels of engagement varied between the examined groups such that the Chemtrail and the Far-Right group disseminated more content with a higher mobilizing potential. The Far-Right group was also the most active in responding to its members. The results of this study are novel in that they demonstrate the prevalence of cues that have been linked to non-normative collective action in psychological research within conspiracy theory-endorsing Facebook groups.

description: External standard calibration is the most common approach used to calculate the unknown concentration of analytes in analytical procedures. However, this method is accurate only if the matrix can be reproduced in the standard samples or if there are no significant interferences in the sample. A well-known calibration method that was proposed especially for the analysis of samples with matrix effects is conventional standard addition method (SAM) which implies adding known and increasing quantities of the analyte to portions of the sample. Despite its benefit of constant matrix effect in the calibration standards, SAM has been frequently shown to be a suboptimal approach with flaws that include extrapolation prediction and thus wider confidence intervals and non-linearity at lower concentrations. Recently, new approaches have been proposed to overcome these shortcomings, including extension of the SAM by blank addition, a geometric alternative for interpolation, and even a new mathematical alternative. Herein, we applied an alternative to extend the SAM method, for semisolid samples with unavailable blank, by adding more samples with lower mass than the unknown in the SAM, and thus extending measurable points below the intercept. This approach was applied for capsaicinoid determination in topical creams after liquid-liquid microextraction, followed by high performance liquid chromatography with diode array detection (HPLC-DAD). Microextraction of the capsaicinoids was optimized in terms of pH, solvent type, vortexing and extraction times. The method appeared to significantly improve the precision, limit of detection, and lead to reduced bias compared to conventional SAM.

description:
Basaltic lunar mare volcanism has erupted a variety of melt compositions that far exceeds that of terrestrial basalts. Most notably, TiO2 contents of lunar basalts vary by almost two orders of magnitude and can reach up to 18 wt.% in red/black primitive pyroclastic glasses [1]. Such high Ti contents point to a role for ilmenite-bearing cumulates (IBC), which are predicted to form near the end of solidification of the lunar magma ocean [2]. No experimental study investigating the melting of pure IBC or mixtures of IBC and peridotite [e.g., 3] has, however, succeeded in reproducing the composition of high-Ti lunar basalts.

We propose that lunar high-Ti basalts originate as IBC partial melts, but have their composition modified through reactive flow in the lunar mantle. We simulate this process by experimentally reacting an IBC partial melt composition [3] with high-Mg# olivine and orthopyroxene crystals at 1400-1500 °C and 1.5 GPa in a piston cylinder press. This leads to a peritectic reaction where orthopyroxene undergoes dissolution-reprecipitation to form a more Ca- and Ti-rich rim, in addition to Fe-Mg exchange between IBC melt and minerals. The composition of the reacted melt shifts to lower Mg# and overlaps with that of high-Ti basalts. No growth of ilmenite or clinopyroxene is observed, thus satisfying the condition that high-Ti melts lack these phases at high-pressure multiple saturation.

description:
Informal educational settings such as science centres play an important role in science education around the world. Science centres are known to have a positive influence on promoting visitors’ curiosity, interests, and knowledge of science because visitors can interact with real objects and engage with exhibits in a relaxed informal environment, watch science shows, or consult websites. In addition to informal education, learning in science centres can also be non-formal through organized, systematic, educational activities such as workshops.

The aim of science centres in South Africa is to develop programs, workshops and undertake outreach programs, which focusses on creating awareness, promoting and teaching science and technology particularly in disadvantaged communities, e.g. rural areas and townships.

The Science and Technology Education Centre at the University of KwaZulu-Natal (STEC@UKZN) in Durban which includes the Geology Education Museum, is one of these science centres. It is a place of hands-on science learning with an emphasis on Geoscience education. Over the years, STEC@UKZN was involved in the development of numerous low-cost geoscience-related activities, exhibits and educational material using an informal and non-formal education approach. While we usually operate face to face, the Covid-19 crisis had us adopt alternatives ways and we had to move some of our activities online.

In our presentation we will highlight our various geoscience initiatives, be it non-formal or informal, face to face or online that take place in the science centre.

description: Adder (Vipera berus) populations are experiencing declines in many countries, including the UK. Perceptions of adders and other venomous snakes are generally negative, making conservation of these species a challenge, and persecution remains within the top five perceived causes for adder declines in the UK. Improved understanding and attitudes are needed to support current conservation efforts. However, ensuring these positive attitudes continue into the future relies on addressing children's loss of connection to nature, and intervention at this early attitude-formation stage can be crucial for traditionally 'unpopular' species, such as snakes. An adder-focussed public-engagement project, Adders are Amazing!, was carried out in Pembrokeshire, UK, in 2018–19 to improve understanding and attitudes towards adders using a blended science-creative arts approach. The project included half-day primary school-based workshops to inform 111 pupils aged 8 to 11 about adder ecology, alongside creative art experiences. Questionnaires were used to measure the children's attitudes towards adders and their nature connectedness both before and after the workshops and these were compared with equivalent questionnaires carried out at a control school (57 pupils) where no workshops were conducted. The project demonstrated that engagement that blends both art and science can significantly change attitudes towards adders without any direct contact with the animals themselves; specifically, participants' scores for 'Wonder', 'Learning Interest' and 'Conservation Concern' increased. The workshops also significantly increased measures of the children's general connectedness to nature (specifically, 'Enjoyment of Nature' and 'Responsibility for Nature'). We recommend conservation bodies focus on, and not shy away from, so-called 'unpopular' species, to promote understanding and acceptance of these species and support their conservation. Blended arts-science initiatives, which can be easily adapted to suit a wide range of species and the artistic practices of local communities, are an effective way to achieve this.

description: Data was collected using a questionnaire administered before and several months following an art/science-based intervention. The intervention's primary aim was to improve attitudes to the adder (Vipera berus), Britain's only venomous snake. Three schools participated, two were part of the intervention, and the other acted as a control school. Questionnaires were summed by hand and the totals for attitudes towards adders, and connectedness to nature were inputted into Excel. Statistical analysis was completed on SPSS v20.

description: Colorectal cancer is a widespread digestive disease. In this study, Fourier transform infrared spectroscopy (FT-IR) and 1H nuclear magnetic resonance (NMR) relaxometry and diffusometry were used for the identification of specific features associated with colorectal cancer from native and deproteinized blood plasma and blood plasma proteins. The blood samples were collected from patients with confirmed colorectal cancer and from healthy volunteers for comparison. The FT-IR spectra were divided into specific regions. A numeric deconvolution procedure was applied in order to quantify the integrated areas of the peaks of interest which were associated with specific responses due to colorectal cancer. The 1H NMR T2- and D-distributions were obtained and quantified. Finally, principal component analysis (PCA) was applied to identify the most important NMR and FT-IR parameters for the differentiation between blood of colorectal cancer patients and blood of healthy volunteers.

description: The pollution with expired drugs of aquatic environments, in particular rivers and lakes, has lately become a major worldwide problem. Thus, the interest in the exact quantity of pharmaceutical waste as well as the management after the expiration date is very high. For the present study, expired drugs in the form of tablets, capsules, and powders collected from the Romanian population and unexpired medicines as the same tablets, capsules, and powders purchased from the local pharmacy were analyzed. Advanced 1H-NMR (proton nuclear magnetic resonance) combined with Laplace data analysis and Fourier transform infrared (FT-IR) spectroscopy were used for the characterization of the unexpired and expired drugs. In order to assess the dynamics of dissolution of drugs in aqueous environment, various kinetic measurements of NMR relaxometry, electrical conductivity (EC) and visible near-infrared spectroscopy were performed and their performance in the differentiation of unexpired and expired drugs was evaluated.

description: The rapid expansion of urban areas and the continuous population growth has resulted in a dramatic increase in the contamination of water bodies with heavy metals, toxic anions, and organic pollutants. As a result, scientists concentrated their efforts on developing new environmentally-friendly composite materials to remove various pollutants from wastewaters through adsorption techniques. Herein, the preparation of a neoteric clay-based material is reported that is capable of complexing metal ions. This new material was obtained from montmorillonite and dopamine-functionalized poly(benzofurane-co-arylacetic) acid. The structure, morphology, and chemical composition of the synthesized material, as well as its sorption capacity for heavy metals, were investigated using a variety of analytical techniques that included scanning electron microscopy (SEM), thermogravimetric analysis (TGA), Fourier-transform infrared spectroscopy (FTIR), and atomic absorption spectrometry (AAS). Stock solutions of Cu, Zn, Mn, Fe, Pb, Cd, Cr, Ni and contaminated surface water samples collected from Roșia River (Roșia Montană Mining Area) were used to evaluate the material’s suitability for metal removal from wastewaters. The results obtained with the new clay-based material highlight its selectivity for certain metals and excellent removal efficiencies on stock solutions (87-100% adsorption efficiency for Fe, Cu, Pb, Cr and Cd) and real contaminated wastewaters (100% adsorption efficiency for Cr and Cd, 96% for Fe and 79% for Cu). Further research should be conducted to optimize the structure of clay-based materials for this type of environmental application in order to increase the number of pollutants adsorbed simultaneously.
