TL;DR: In this article , a solid-solution strategy was proposed to stabilize Cu2+ ions by incorporating them into a CeO2 matrix, which works as a self-sacrificing ingredient to protect the active sites.
Abstract: Copper is the only metal catalyst that can perform the electrocatalytic CO2 reduction reaction (CRR) to produce hydrocarbons and oxygenates. Its surface oxidation state determines the reaction pathway to various products. However, under the cathodic potential of CRR conditions, the chemical composition of most Cu-based catalysts inevitably undergoes electroreduction from Cu2+ to Cu0 or Cu1+ species, which is generally coupled with phase reconstruction and the formation of new active sites. Since the initial Cu2+ active sites are hard to retain, there have been few studies about Cu2+ catalysts for CRR. Herein we propose a solid-solution strategy to stabilize Cu2+ ions by incorporating them into a CeO2 matrix, which works as a self-sacrificing ingredient to protect Cu2+ active species. In situ spectroscopic characterization and density functional theory calculations reveal that compared with the conventionally derived Cu catalysts with Cu0 or Cu1+ active sites, the Cu2+ species in the solid solution (Cu-Ce-Ox) can significantly strengthen adsorption of the *CO intermediate, facilitating its further hydrogenation to produce CH4 instead of dimerization to give C2 products. As a result, different from most of the other Cu-based catalysts, Cu-Ce-Ox delivered a high Faradaic efficiency of 67.8% for CH4 and a low value of 3.6% for C2H4.

TL;DR: The major mechanisms and pathways by which bivalve and seaweed aquaculture may positively influence the structure and function of faunal communities are described—including provision of structured habitat, provision of food resources and enhanced reproduction and recruitment—and the role of the species cultivated and cultivation gear in affecting habitat value is identified.
Abstract: Aquaculture can have negative environmental impacts, adding to the suite of anthropogenic stressors that challenge coastal ecosystems. However, a growing body of scientific evidence indicates that the commercial cultivation of bivalve shellfish and seaweed can deliver valuable ecosystem goods and services, including provision of new habitats for fish and mobile invertebrate species. We completed a systematic literature review of studies focused on understanding habitat-related interactions associated with bivalve and seaweed aquaculture, and a brief meta-analysis of 65 studies to evaluate fish and mobile macroinvertebrate populations at farms and reference sites. Bivalve and seaweed aquaculture were associated with higher abundance (n = 59, range: 0.05× to 473×, median lnRR = 0.67) and species richness (n = 29, range: 0.68× to 4.3×, median lnRR = 0.13) of wild, mobile macrofauna. Suspended or elevated mussel and oyster culture yielded the largest increases in wild macrofaunal abundance and species richness. We describe the major mechanisms and pathways by which bivalve and seaweed aquaculture may positively influence the structure and function of faunal communities—including provision of structured habitat, provision of food resources and enhanced reproduction and recruitment—and identify the role of the species cultivated and cultivation gear in affecting habitat value. Given the continued deterioration of coastal habitats and increasing investments into their restoration, understanding how industry activities such as aquaculture can be designed to deliver food within ecological limits and have positive influences on ecosystem goods and services is essential in ensuring ecological, social and economic objectives can be achieved.

TL;DR: Scoping reviews as mentioned in this paper are a type of evidence synthesis that aims to systematically identify and map the breadth of evidence available on a particular topic, field, concept, or issue, often irrespective of source (i.e., primary research, reviews, non-empirical evidence) within or across particular contexts.
Abstract: Evidence synthesis encompasses a broad range of review types, and scoping reviews are an increasingly popular approach to synthesizing evidence in a number of fields. They sit alongside other evidence synthesis methodologies, such as systematic reviews, qualitative evidence synthesis, realist synthesis, and many more. Until now, scoping reviews have been variously defined in the literature. In this article, we provide the following formal definition for scoping reviews: Scoping reviews are a type of evidence synthesis that aims to systematically identify and map the breadth of evidence available on a particular topic, field, concept, or issue, often irrespective of source (ie, primary research, reviews, non-empirical evidence) within or across particular contexts. Scoping reviews can clarify key concepts/definitions in the literature and identify key characteristics or factors related to a concept, including those related to methodological research.

TL;DR: In this article , a vanadium pentoxide/graphitic carbon nitride (V2O5/C3N4) S-scheme with a facile approach was proposed for removing deleterious antibiotics residues in the water environment.
Abstract: Innovative solar-driven heterostructure photocatalysts are promising for removing deleterious antibiotics residues in the water environment. Herein, we prepared a vanadium pentoxide/graphitic carbon nitride (V2O5/C3N4) S-scheme with a facile approach. The heterostructure provides larger surface areas, promotes the separation and transfer of charge carriers, and offers abundant active sites for photocatalytic redox reactions. The composites were used to degrade amoxicillin (AMX) under solar light which attained a high removal efficiency (91.3%) and stability. Meanwhile, the photodegradation pathway of AMX was revealed by HPLC-MS/MS analysis and density functional theory (DFT) computations. Superoxide radicals evolved from conduction band of C3N4 and oxidative holes were generated from valence band of V2O5, which were confirmed by electron spin resonance experiments and selective radical quenching experiments. The V2O5/C3N4 S-scheme structure provides an internal electron channel at the interface and maintains the active sites with high potentials for photodegradation. Our work affords a robust V2O5/C3N4 S-scheme nanocomposites for sustainable water purification.

Abstract: Carbon quantum dots (CQDs) have attracted intensive interest in the scientific community attributed to their quantum effect, non-toxicity, fluorescence, photoluminescence, and up-conversion properties, and have been extensively applied in sensing, biomedical, optoelectronic and catalysis fields. Especially, CQDs can act as photocatalysts and be used in energy and environmental areas, such as wastewater remediation and solar energy conversion to fuels and green chemicals. This review will briefly introduce the unique physicochemical properties of CQDs, such as light absorption, photoluminescence, and up-conversion luminescence. The advanced fabrication methods and modification strategies of CQDs will also be summarized. Finally, we will show the broad applications of CQDs in photocatalytic pollutant removal and hydrogen/hydrogen-peroxide production, discussing the structure-activity relationship of CQDs and their complexes in the field of catalysis. Lastly, the key issues and perspectives for future energy and environmental applications are presented. This comprehensive review will provide new insight and inspiration in the synthesis, improvement, and photocatalytic application of CQDs.

TL;DR: In this paper, a coupled nonlinear dynamics of hyperelastic beams is investigated using 3D printing technique for flexible thermoplastic polyurethane filaments following the ASTM D638 guidance and tested using a tensile testing machine.
Abstract: Comprehensively investigated in this paper is the coupled nonlinear dynamics of hyperelastic beams. Experimental testing is performed to accurately model the hyperelasticity using different hyperelastic energy density models. Samples were fabricated using 3D printing technique for flexible thermoplastic polyurethane filaments following the ASTM D638 guidance and tested using a tensile testing machine. For a proper hyperelastic energy density model, coupled nonlinear equations of motion are obtained via the von Karman geometrical nonlinearity and Hamilton’s principle. Free natural vibration response of the gyroscopic system is analysed using a generalised modal decomposition method and the influence of different parameters such as the hyperelastic stiffness term and the axial velocity on the natural frequencies is investigated. Complex mode shapes are obtained and the influence of axial velocity on altering the real and imaginary parts is discussed. Furthermore, a comprehensive analysis on the coupled nonlinear dynamics of the system is presented using a combination of Galerkin’s scheme and a dynamic equilibrium technique. The frequency response to different design parameters such as axial speed, axial tension, harmonic external load, hyperelastic parameters and geometrical imperfection is discussed in detail. It is shown that the system shows a wide range of rich nonlinear dynamics including hardening depending on the characteristics of the system.

TL;DR: Wang et al. as discussed by the authors found that MSW-derived biochar possesses great potential in wastewater purification by adsorption and catalysis, which facilitates the popularization of the innovative mode "waste control by waste" in aquatic environment remediation.
Abstract: A huge amount of municipal solid waste (MSW) is produced with urbanization process, posing serious threats to the surroundings and human health. The preparation of MSW-derived biochar is an effective strategy for the waste reclamation. MSW-derived biochar possesses great potential in wastewater purification by adsorption and catalysis. In this review, biochar prepared from classified MSW (e.g. food waste and waste paper) was found with larger specific surface area and porosity than the mixed MSW-derived biochar. Meanwhile, pre-treatment and post-treatment means are summarized to improve the structure and composition of biochar, which could further strengthen its adsorption capacity and catalytic activity. The -COOH, -C = O, -C = C, -OH group sites and aromatic structure of MSW-derived biochar could adsorb pollutants through electrostatic interaction, surface complexation, ion exchange, hydrogen bonding and π-π interaction. Moreover, thanks to the -COOH, -C = O, -OH groups, N-doped structures, defective sites and iron ion species, the food waste-derived biochar exhibits excellent persulfate activation properties. Finally, the future challenges and research directions are suggested, which is conductive to promoting the resource utilization of MSW. Some consideration and recommendation about MSW-derived biochar for water treatment are provided, which facilitates the popularization of the innovative mode “waste control by waste” in aquatic environment remediation.

TL;DR: The findings demonstrate that tool-related challenges and solutions were the most frequently reported, driven by the need for automation in this paradigm, and highlight the need of developer-centered application security testing tools that target the continuous practices in DevSecOps.
Abstract: Context: DevOps (Development and Operations) has become one of the fastest-growing software development paradigms in the industry. However, this trend has presented the challenge of ensuring secure software delivery while maintaining the agility of DevOps. The efforts to integrate security in DevOps have resulted in the DevSecOps paradigm, which is gaining significant interest from both industry and academia. However, the adoption of DevSecOps in practice is proving to be a challenge. Objective: This study aims to systemize the knowledge about the challenges faced by practitioners when adopting DevSecOps and the proposed solutions reported in the literature. We also aim to identify the areas that need further research in the future. Method: We conducted a Systematic Literature Review of 54 peer-reviewed studies. The thematic analysis method was applied to analyze the extracted data. Results: We identified 21 challenges related to adopting DevSecOps, 31 specific solutions, and the mapping between these findings. We also determined key gap areas in this domain by holistically evaluating the available solutions against the challenges. The results of the study were classified into four themes: People, Practices, Tools, and Infrastructure. Our findings demonstrate that tool-related challenges and solutions were the most frequently reported, driven by the need for automation in this paradigm. Shift-left security and continuous security assessment were two key practices recommended for DevSecOps. People-related factors were considered critical for successful DevSecOps adoption but less studied. Conclusions: We highlight the need for developer-centered application security testing tools that target the continuous practices in DevSecOps. More research is needed on how the traditionally manual security practices can be automated to suit rapid software deployment cycles. Finally, achieving a suitable balance between the speed of delivery and security is a significant issue practitioners face in the DevSecOps paradigm.
