Reduction pathway-dependent cytotoxicity of reduced graphene oxide

The environmental transformation of graphene oxide (GO) can significantly change its physicochemical properties, thus altering its toxicity. Here, we demonstrated how exposure to simulated sunlight or reduction with ferrous iron (Fe2+, an environmentally abundant and mild reductant) significantly impacts the cytotoxicity of GO. GOs were reduced under both sets of conditions, but the Fe2+-reduced GO showed dramatically lower cytotoxicity than did the light-reduced GO. A highly reactive graphene-based radical was generated when GO was exposed to light, and this radical significantly contributed to cell membrane oxidation. Moreover, light-induced reduction promoted breakage of the graphene sheet, decreasing the lateral size and increasing the ability of the material to disrupt the membrane, which consequently enhanced cellular uptake. Interestingly, we observed a loss of C–O–C/C–O groups but an increase in CO/O–CO groups during Fe2+ reduction; these alterations improved the radical quenching capacity of the material due to the restored sp2 structure and the increase in electron-shuttering groups. Reduction-induced aggregation significantly decreased cellular uptake relative to the internalization of the parent GO. These results emphasize that environmental transformation-induced property changes should be given adequate consideration in the risk assessment of GO.
School Scientific Argumentation Enriched by Digital Technologies: Results With Pre- and in-Service Science Teachers

This article focuses on the integration of argumentation and digital technologies in science teacher education. We present theoretical reflections, results of empirical research, and description of innovative experiences with pre- and in-service biology teachers. Regarding argumentation, we analyse what defending a claim in science entails for teachers, the teaching strategies they (would) use in the classroom in relation to argumentation, the relevance that they attribute to the performance of different tasks for arguing, the subject content where argumentation fits more suitably, and the reasons they would consider in favour of arguing in science classes. For the analysis of educational practices that involve use of technologies, we adopt a perspective that looks at their complexity and recognises teachers as their creative authors. We discuss the way in which teachers (would) use technologies in their practice, their expectations around this, and the foreseen results with students. Finally, we examine three innovative educational experiences already implemented, using argument maps, web-based inquiry, and a digital game. We look into the possibilities that these technological resources offer for teachers to analyse the argumentation levels reached by their students.
Defect Creation in HKUST‐1 via Molecular Imprinting: Attaining Anionic Framework Property and Mesoporosity for Cation Exchange Applications

Discovering new methods to tailor the physical and chemical properties of metal–organic frameworks (MOFs) for their numerous potential applications is highly desired. In this work, engineering defects in MOF via a molecular imprinting approach is developed to endow HKUST‐1, a well‐studied classical MOF, with hierarchical structure, mesoporosity, and anionic framework property. Ringlike anionic HKUST‐1 (HKUST‐1‐R) and a wide variety of metal‐doped isostructural analogues (M/HKUST‐1‐R, M = Ca, Cd, Ce, Co, Li, Mn, Na, Ni, or Zn) are obtained. The benefits of transforming imprinted HKUST‐1‐R to M/HKUST‐1‐R are further demonstrated for various applications. This synthetic strategy is therefore suitable for rational design and functionalization of MOFs in addition to their morphological control in nanoscale.
A Network Approach to Understanding Narcissistic Grandiosity via the Narcissistic Admiration and Rivalry Questionnaire and the Narcissistic Personality Inventory

ABSTRACT The narcissistic admiration and rivalry concept (NARC) model of grandiose narcissism posits that striving for uniqueness, grandiose fantasies, and charmingness define narcissistic admiration, whereas striving for supremacy, devaluation, and aggressiveness define narcissistic rivalry. Given these complex interrelationships, we explored the structure of grandiose narcissism using the Narcissistic Admiration and Rivalry Questionnaire (NARQ) and Narcissistic Personality Inventory (NPI) via network analysis in four separate samples which allowed us to assess the extent to which these networks replicated across these samples (total N = 3,868). Overall, grandiose cognitions from the NARQ emerged as a highly central node in each network, providing compound evidence for its replicability and generalizability as an important feature of grandiose narcissism within the NARC model. Charmingness from the NARQ emerged as a central node throughout Samples 1, 2, and 3, with strong connections to features of narcissistic admiration and narcissistic rivalry (e.g., grandiose fantasies and aggressiveness), but was less central in Sample 4. To our knowledge, this is the first research to examine the replicability of the network structure of grandiose narcissism across various samples. These findings add to an increasingly important dialogue regarding replicability in psychological network science.
Combining Methods to Better Estimate Total Fish Richness on Temperate Reefs: The Case of a Mediterranean Coralligenous Cliff

Coralligenous habitat is considered as one of the most important special habitat types in the Mediterranean; however, due to its inaccessibility, little is known about it, although it is considered as one of the Mediterranean’s richest habitats in terms of species. Due to a low number of studies, it was presumed that the richness of coralligenous fish assemblages is underestimated using traditional visual census methods which are not applicable to the deep, steep, and vertical slopes of coralligenous cliffs and do not capture exhaustively cryptobenthic species commonly found in this habitat. This paper aims at producing a more complete assessment of fish assemblages on a coralligenous cliff by combining different methods, particularly the deep vertical transect visual census and square with anesthetics method. A total of 76 fish species were recorded on a single coralligenous cliff, supporting the opinion that coralligenous cliffs are important Mediterranean biodiversity hotspots. The analysis of species traits between species recorded by the different methods showed how complementary they are to better describe species compositions. Hence, the result of this study demonstrates that the combined use of methods is essential for a more exhaustive description of the whole fish community structure and for accurate estimates of the abundance and diversity patterns, particularly in complex habitats such as coralligenous cliffs.
Development of an Optimized NDT Methodology for the Investigation of Ancient Greek Copper-Based Artifacts

A multi-analytical non-destructive testing (NDT) methodology was applied to copper-based artifacts originated from various archaeological sites of Greece. X-ray fluorescence (XRF), fiber optics diffuse reflectance spectroscopy (FORS) and scanning electron microscopy coupled with an energy dispersive X-ray detector (ESEM-EDX) were used for the characterization of the alloys and the corrosion products. The key elements of the artifacts belonging to the Early Bronze Age (2700–2300 BC) were copper and arsenic, while tin bronze was used for the fabrication of the Late Bronze Age (1600–1100 BC) artifacts. The effectiveness of XRF for the determination of the bulk composition was confirmed by comparative study with the previously applied atomic absorption spectroscopy (AAS) and inductively coupled plasma–atomic emission spectrometry (ICP-AES) destructive techniques. Significant differences between the artifacts were revealed through the spectral measurement of their surface corrosion products color by FORS. ESEM-EDX provided information on the microstructure, the elemental composition of the corrosion layers and bulk, as well as the distribution of the corrosion products on the surface. Conclusively, the combined NDT methodology could be regarded as a valuable and appropriate tool for the elemental composition of the bulk alloy, thus leading to the classification of their historical period and the corrosion products, contributing significantly to their conservation–restoration.
Behavioural test battery for the Back of the Brain project

Much of the patient literature on the visual recognition of faces, words and objects is based on single case studies of patients selected according to their symptom profile. The Back of the Brain project aims to provide novel insights into the cerebral and cortical architecture underlying visual recognition of complex stimuli by adopting a different approach. A large group of patients was recruited according to their lesion location (in the areas supplied by the posterior cerebral artery) rather than their symptomatology. All patients were assessed with the same battery of sensitive tests of visual perception enabling the identification of dissociations as well as associations between deficits in face, word and object recognition. This paper provides a detailed description of the extensive behavioural test battery that was developed for the Back of the Brain project and that enables assessment of low-level, intermediate and high-level visual perceptual abilities. •Extensive behavioural test battery for assessing low-level, intermediate and high-level visual perception in patients with posterior cerebral artery stroke •Method enabling direct comparison of visual face, word and object processing abilities in patients with posterior cerebral artery stroke
An Acrylonitrile–Butadiene–Lignin Renewable Skin with Programmable and Switchable Electrical Conductivity for Stress/Strain-Sensing Applications

We report an approach for programming electrical conductivity of a bio-based leathery skin devised with a layer of 60 nm metallic nanoparticles. Lignin-based renewable shape-memory materials were made, for the first time, to program and restore the materials’ electrical conductivity after repeated deformation up to 100% strain amplitude, at a temperature 60–115 °C above the glass transition temperature (Tg) of the rubbery matrix. We cross-linked lignin macromolecules with an acrylonitrile–butadiene rubbery melt in high quantities ranging from 40 to 60 wt % and processed the resulting thermoplastics into thin films. Chemical and physical networks within the polymeric materials significantly enhanced key characteristics such as mechanical stiffness, strain fixity, and temperature-stimulated recovery of shape. The branched structures of the guaiacylpropane-dominant softwood lignin significantly improve the rubber’s Tg and produced a film with stored and recoverable elastic work density that was an order of m.
Overcoming bit loss mechanism in self‐amplified multilevel silicon‐oxide‐nitride‐oxide‐silicon memory cell

This work reports on the triple‐level NAND flash cell realized from self‐amplified (SA) double gate (DG) tunneling‐based silicon‐oxide‐nitride‐oxide‐silicon (T‐SONOS) memory device. Through calibrated simulations, we show that capacitive coupling between the front gate and back gate can be used to store eight states (or 3 bits), that is, from “000” to “111,” in a T‐SONOS memory device with the readable difference between each level at lower programming voltages. The performance of the multilevel T‐SONOS cell is compared with the inversion mode SONOS (I‐SONOS) multilevel cell. Results highlight that gate length (Lg) scaling from 100 to 25 nm significantly deteriorates the threshold voltage associated with the lower states in the I‐SONOS multilevel cell. However, highly stable eight states can be achieved in a multi‐level T‐SONOS cell at Lg = 25 nm. The results highlight the potential of SA T‐SONOS cell for designing multilevel memory cell arrays.
Preparation of Hierarchical Porous Carbon from Waterweed and Its Application in Lithium/Sulfur Batteries

A nanostructured carbon (NSC) material with a hierarchical porous structure is synthesized through the carbonization of a waterweed, namely Echinodorus amazonicus Rataj. The fabricated NSC is used as an electrode material for sulfur of lithium/sulfur (Li/S) batteries. The NSC provides for a high pore volume (0.19 cm 3 g −1 ) and large specific surface area (111.25 m 2 g −1 ). Because of the highly hierarchical porous structure of the NSC material, allowing polysulfides to remain in the carbon framework after cycling, the sulfur/NSC composite exhibits an excellent electrochemical performance.

Scientometric Analysis of Diesel Pollutions in Antarctic Territories: A Review of Causes and Potential Bioremediation Approaches

Despite the continuous enforcement of Antarctic Treaty System, ATS (1961), today Antarctica is constantly plagued by hydrocarbon pollution from both legacy and present-day wastes, especially near where anthropogenic activities are the most intense. The advances of science have led to multiple breakthroughs to bolster bioremediation techniques and revamp existing laws that prevent or limit the extent of hydrocarbon pollution in Antarctica. This review serves as the extension of collective efforts by the Antarctic communities through visual representation that summarizes decades of findings (circa 2000–2020) from various fields, pertinent to the application of microbe-mediated hydrocarbons remediation. A scientometric analysis was carried out based on indexed, scientific repositories (ScienceDirect and Scopus), encompassing various parameters, including but not limited to keywords co-occurrences, contributing countries, trends and current breakthroughs in polar researches. The emergence of keywords such as bioremediation, biosurfactants, petroleum hydrocarbons, biodiesel, metagenomics and Antarctic treaty policy portrays the dynamic shifts in Antarctic affairs during the last decades, which initially focused on exploration and resources exploitation before switching to scientific research and the more recent ecotourism. This review also presents the hydrocarbonoclastic microbes studied in the past, known and proposed metabolic pathways and genes related to hydrocarbon biodegradation as well as bacterial adaptations to low-temperature condition.
Eutrophication reduces seagrass contribution to coastal food webs

Food sources and food web structure in seagrass meadows are important determinants of ecosystem functions and services. However, there is little information on the effect of eutrophication on food source contributions and food web structure in seagrass meadows. Here we used stable isotopes of carbon and nitrogen ( δ 13 C and δ 15 N) to investigate how do different levels of nutrient enrichment affect the diets of consumers and food web structure within tropical seagrass meadows. We found that the diet contributions of macroalgae (mean 24% (cid:1) 12% for ﬁ sh, 21% (cid:1) 5% for invertebrates), particulate organic matter (mean 19% (cid:1) 12% for ﬁ sh, 18% (cid:1) 8% for invertebrates), and sediment organic matter (mean 24% (cid:1) 13% for ﬁ sh, 21% (cid:1) 8% for invertebrates) to ﬁ sh and invertebrates were all higher in seagrass meadows with higher nutrient concentrations, while seagrass and epiphytes contributed more to consumers in seagrass meadows with lower nutrient concentrations. Meanwhile, higher nutrient concentrations decreased the trophic position (mean 2.6 (cid:1) 0.5 in high-nutrient level, 3.4 (cid:1) 0.6 in low-nutrients level) of consumers and food chain length (2.5 in high-nutrient level, 2.9 in low-nutrients level). Higher nutrient concentrations reduced the contribution of seagrass carbon to consumers through the grazing food chain, but enhanced the ﬂ ow of macroalgal carbon to consumers through the grazing food chain. Overall, eutrophication modi ﬁ ed the food web structure of seagrass meadows. We recommend that measures be taken to decrease nutrient input into seagrass ecosystems to maintain its important functions and services.

RELATIONSHIP BETWEEN JOB PERFORMANCE, WELL-BEING, JUSTICE, AND ORGANIZATIONAL SUPPORT: A MULTILEVEL PERSPECTIVE

ABSTRACT Purpose: This research was based on the "happy, productive worker" hypothesis. The objective was to analyze the predictive relationships, through a multilevel approach, between the variables well-being at work, organizational justice, organizational support, and the dependent variable individual job performance. Originality/value: The multilevel study of individual job performance and its relations with well-being and organizational variables are still a current gap in the literature, as well as the possibility of testing whether well-being at work can be considered a collective phenomenon. The presence of organizational support in the model, operationalized at the team level, represents an important contribution to the development of theories focused on teams' roles in organizations, especially their impact on organizational variables. Design/methodology/approach: Considering the proposed analysis at two different levels, a multilevel design model was adopted. The final sample consisted of 730 individuals and 32 units. The data were collected through a questionnaire composed of four previously validated scales. Data analysis followed the six steps proposed by Hox, Moerbeek, and Schoot (2017) for multilevel models for each of the samples. Findings: The explanatory model presented a predictive relationship between achievement (well-being at work factor), operationalized as an individual-level variable, and individual job performance; a predictive relationship between interactional justice, also operationalized as an individual-level variable, and individual job performance, and a predictive relationship between collective perceptions of organizational support, operationalized as a team-level variable, and individual job performance.
