CO2 Activation on Single-Atom Catalysts: Importance of the Supporting Matrix
Authors: Spotti Matteo , Di Liberto Giovanni , Pacchioni Gianfranco 
Published: February 2025

Abstract
Single-Atom Catalysis (SACs) is an emerging frontier with significant potential to bridge the gap between homogeneous and heterogeneous catalysis. Among various chemical processes of interest, the reduction of CO2 (CO2RR) into valuable chemicals has garnered particular attention. The analogy between SACs and coordination chemistry compounds has highlighted the importance of the supporting matrix. In this study, we explored CO2 activation on SACs using density functional theory (DFT) calculations. Our analysis focused on nine transition metals (Fe, Co, Ni, Ru, Rh, Pd, Os, Ir, Pt) and three distinct support materials: nitrogen-doped graphene (4N-Gr), a gold surface (Au(111)), and titanium nitride (TiN), an emerging material with unique properties. Our findings indicate that CO2 activation on SACs is generally challenging, often requiring dual active centers. SACs based on 4N-Gr and Au(111) showed limited ability to bind CO2 molecules. Conversely, TiN emerged as a highly promising support, effectively promoting CO2 activation. This capability stems from the formation of bidentate adducts involving both the dopant and a surface titanium atom of the matrix. Furthermore, TiN-based SACs demonstrated the ability to favour *CO*OH adduct formation (* indicates an adsorbed species) over *COOH or *OCHO during the first electrochemical reduction step, showcasing enhanced reactivity. These results underscore the potential of TiN as a robust support material for SACs in CO2RR, offering new perspectives for efficient CO2 conversion.
Conviviality: our primary connectedness to living beings
Authors: Fuchs Thomas 
Published: February 2025

Abstract
In the ecological discourse on nature and the environment, the natural side of humans, which we experience as our own corporeality, plays hardly any role. To address this deficiency, the paper proposes the concept of conviviality. It refers to a primary connection with the living environment, conveyed through our own sense of aliveness and embodiment. The concept encompasses three interconnected aspects: 1) An epistemological aspect, according to which we can only recognize other living beings as such and distinguish them from inanimate things through the experience of our shared bodily existence; 2) A natural-philosophical and ecological aspect, which relates to the fundamental interdependence of all living beings and the interpenetration of life and the environment; 3) An ethical aspect, where our kinship and connection with living beings form the basis for an attitude of care and commitment towards them. The three aspects are based on the same fundamental structure, namely the interdependence of the living, both in subjective, phenomenal terms, and in objective, ecological terms. At the same time, they are grounded in our corporeality, which points to the relational nature of our existence, our life in relationships and in ecological contexts. In this way, the fundamental kinship of our lived bodies with living nature becomes the basis for an ecological ethic.
Scientific relevance and affinity in the declarations of the groups and academic disciplines in physical exercise and sport sciences
Authors: Raiola Gaetano , Esposito Giovanni , Aliberti Sara , Ceruso Rosario , D’Elia Francesca 
Published: February 2025

Abstract

Purpose
In Italy, following the definition of scientific-disciplinary groups (SDG) and the update of academic disciplines (AD) with their respective declarations, a significant legislative change occurred. This led to the merging of the two ADs of Physical Training Sciences and Methodology (code M-EDF/01) and Sport Sciences and Methodology (code M-EDF/02) into a single SDG called Physical Exercise and Sport Sciences. Consequently, there should be full scientific autonomy for this new SDG. However, residual interference from the former related ADs persists, which is now redundant, since the new SDG encompasses all relevant affinities. Therefore, other ADs and SDGs should not reference the SDG and ADs titles of Physical Exercise and Sport Sciences in their declarations. The study aimed to verify if there were any duplications compared to the previous university body, to what extent these duplications existed, and to identify the specific instances of duplication.

Methods
A textual analysis of the scientific declarations of the 190 SDGs and 383 ADs was conducted in comparison with the corresponding previous declarations of the academic recruitment fields (ARF) and ADs. The analysis was conducted using specific keywords.

Results
The analysis of Ministerial Decree (DM) n. 639 of 2024 found that the keyword “Sport” is present in 21 SDGs and 23 ADs, ranging from zoology and physiology to aerospace engineering and law. For “Physical training or education or exercise”, 7 SDGs and 6 ADs were identified, including musculoskeletal system diseases, cellular biology, and special education. Compared with the DM n. 885 of 2000, the keyword “Sport” appears in 15 ARFs and 10 ADs, while “Physical training or education or exercise” appears in 13 ARFs and 9 ADs, in similar areas.

Conclusions
The overlaps in the scientific declarations of the 180 SDGs and the 383 ADs were supposed to decrease due to their unique scientific, cultural, and educational relevance and affinity; instead, they have increased. Similarly, this occurred with the updated declarations of the ADs. An even more concerning aspect is that the declaration of SDG in Area 11 of Historical, Philosophical, Pedagogical and Psychological Sciences contains a significant overlap between the SDG of Educational research, teaching, special pedagogy, and experimental pedagogy (code 11/PAED-02) and the SDG of Physical Exercise and Sport Sciences (code 06/MEDF-01), perpetuating the current confusion.

Authors: Schoenherr Johanna , Schukajlow Stanislaw , Pekrun Reinhard 
Published: February 2025

Abstract
Academic emotions play a crucial role in mathematics learning, significantly influencing motivation, academic achievement, and career aspirations in mathematics. With the notable increase in research on emotions in recent years, our review uses Pekrun’s control-value theory with two primary objectives: to systematically describe the characteristics of emotions in recent research through a systematic review, and to synthesize evidence on the relationships between specific emotions, control-value antecedents, and mathematics achievement via a meta-analysis. The systematic review of 112 studies revealed that more than 100 specific emotions have been addressed in recent research, which we analyzed based on key emotion characteristics: valence and activation, type of object, temporal stability, and social context. The findings from the systematic review provide an overview of mathematics-specific objects that emotions have referred to in the most recent research. The subsequent meta-analysis demonstrated that mathematics achievement (e.g., test scores and grades) was positively related to enjoyment, hope, and pride (

Published: February 2025

Abstract
The spice industry faces significant challenges in ensuring the safety and quality of its products, mainly since they are commonly consumed raw. Whilst effective in inactivating pathogens, thermal treatments often degrade the sensory quality of spices, making them unfeasible. This study explores the potential of short wavelength ultraviolet (UV) disinfection as a non-thermal alternative, focusing on its disinfection efficacy and impact on the quality of black, white, green, and pink peppercorns from various geographical sources. A substantial reduction in Escherichia coli was demonstrated using an industrially scalable rotary reactor, with the highest reductions observed in green and black peppercorns. The use of the reactor proved to be more effective than a static treatment, highlighting the importance of uniform distribution of the UV light exposure. The results demonstrated that the antioxidant activity, total phenolic content, and piperine content remained unaltered following UV-C treatment in most of the samples. This finding indicates that the sensory characteristics of the peppers were not significantly altered, whilst food safety was enhanced. Nevertheless, additional research on sensory analysis is necessary to understand the impact on sensory perception and the potential of LED-based UV lamps as an effective and efficient method for ensuring food safety in the spice industry.
Happy-productive worker hypothesis in the context of education: the role of work engagement and its dimensions

Published: February 2025

Abstract
The happy-productive worker hypothesis, considered a significant concept in management research, continues to generate debate and lacks conclusive evidence. In this study, two dimensions of wellbeing: Wellbeing as context-free (psychological wellbeing), and Work-related wellbeing (job satisfaction), were examined on the performance of distance education facilitators in Ghana. In addition, work engagement and its dimensions were introduced as mediators in explaining why happy workers are more productive. A three-wave time-lagged data was collected from 431 facilitators working in two distance education institutions in Ghana. The results revealed that wellbeing as context-free did not have a direct impact on performance but rather an indirect impact on performance via work engagement and two of its dimensions (vigor and absorption). However, work-related wellbeing had both direct and indirect effects on performance via work engagement and one of its dimensions (absorption). In light of the study’s findings, the happy-productive worker hypothesis was generally supported, but the study concluded that the hypothesis is more nuanced than initially perceived. Therefore, organizational management, including educational management, should develop and implement effective interventions to promote their employees’ wellbeing.
Exploring the relationship between learning climate in schools and agile leadership using multi-group path analysis: does “Willingness to work” have a mediating role?
Authors: Sözer Boz Esra , Tabak Hasan 
Published: February 2025

Abstract
The learning climate in schools is significantly influenced by relationships among teachers, students, and school administration. Despite its importance, relatively few studies have explored the relationship between learning climate and principal characteristics from teachers’ perspectives. This study aims to examine the mediating role of teachers’ willingness to work in the relationship between the learning climate in schools and agile leadership. The participants consist of 630 teachers from various educational levels, ranging from preschool to high school. Data were collected using the Agile Leadership Scale, the Learning Climate Scale, and an item assessing teachers’ willingness to work. Mediation analysis was employed to examine the impact of teachers’ willingness to work on the relationship between agile leadership and the learning climate in schools. The findings revealed that willingness to work serves as a mediator in the relationship between the learning climate in schools and agile leadership. Multi-group path analysis indicated that this mediation effect was significant among male teachers, whereas they were not observed among female teachers. The overall results demonstrate that the learning climate in schools is affected by the agile leadership of the principals, and the willingness to work of teachers partially mediated this relationship. These findings underscore the importance of agile leadership behaviors in fostering a conducive learning climate and suggest that supporting teachers’ professional and personal development can further enhance this environment.
Evidence-based Lead Indicators to Drive Equitable Early Years Services: Findings from the Restacking the Odds Study
Authors: Molloy Carly , Perini Nick , Harrop Chris , Goldfeld Sharon 
Published: February 2025

Abstract
Children living in adversity are disproportionately affected by inequities in early childhood health and education service delivery, leading to differential outcomes that track into adulthood. Previous research has demonstrated the inconsistency, lack of effectiveness, and harm that human services can cause across the social sector when service delivery is poor. A significant factor preventing equitable responses to performance challenges is the lack of relevant data. In both health and education sectors there is an over-reliance on outcome or lag indicators; necessary but not sufficient to drive change. Evidence-based process or lead indicators can provide a standardised approach to service improvement that allow communities, health and education professionals, governments, and policymakers to create sustainable systems change, reduce unjust equity gaps and reduce the costs associated with poor service provision. The Restacking the Odds (RSTO) ‘proof of concept’ project aimed to address some of the data limitations practitioners and policy-makers face as they make decisions affecting early years services in Australia. An actionable, evidence-based framework of lead indicators for quality, quantity, and participation across five early years services was derived from the literature. These are summarised in this paper together with the subsequent data collected and analysed against these indicators in seven Australian communities.
Integrating simulation and machine learning for accurate preform charge prediction in Sheet Molding Compound manufacturing
Authors: Tannous Mikhael , Rodriguez Sebastian , Ghnatios Chady , Chinesta Francisco 
Published: February 2025

Abstract
The Sheet Molding Compound (SMC) process is essential in high-volume manufacturing of composite structures due to its scalability and efficiency. A primary challenge, however, lies in determining the initial charge shape that ensures complete mold filling without excessive overflow, typically resolved through labor-intensive trial and error. While simulations can anticipate the mold filling outcome, they often lack the capability to fine-tune the initial preform configuration, leading to inefficiencies in both time and material. This study presents an innovative, simulation-driven approach for accurately predicting initial charge shapes for two-dimensional (2D) mold designs. By employing Darcy’s Law and a fixed mesh grid framework, the methodology simulates a reverse material flow to trace the optimal preform shape. A complementary machine learning (ML) model was then developed to predict the preform shapes based on mold geometry, final thickness, and initial charge thickness. Serving as a digital twin of the SMC process, this ML model delivers results with comparable accuracy to simulations, significantly enhancing computational efficiency and avoiding common convergence issues in traditional simulations. This ML-driven digital twin approach also provides a robust proof of concept for addressing initial charge shapes in complex three-dimensional (3D) molds, where the computational demands of reverse flow simulations may present challenges. This combined simulation and ML framework equips manufacturers with a more precise and efficient tool for optimizing SMC processes, minimizing material waste, and reducing production time.
A proposed integrated methodology for evaluation and adjustment of Balance of Performance (BoP) schemes in Grand Touring (GT) racecar championships
Authors: Kottas Angelos T. , Bozoudis Michail N. , Madas Michael A. 
Published: February 2025

Abstract
The concept of Balance of Performance (BoP) has been extensively applied to various forms of motorsports, and especially championships involving Grand Touring (GT) racecars. The organizing bodies of these championships have devised schemes restricting various technical features of the participating racecars, in order to achieve competition parity and subsequently avoid dominance of certain racecars. BoP schemes mainly focus on adjusting engine horsepower and racecar weight, additionally including provisions for restrictions pertinent to aerodynamics, suspension, fuel tank capacity, etc. However, the methodology used by the organizing bodies of motorsports championships in order to evaluate and adjust the BoP schemes is not so transparent to competitors and other interested parts (e.g., racecar manufacturers). In fact, no motorsports organizing body applying the BoP concept to GT racecars, has disclosed details associated with imposing, evaluating, and adjusting the BoP scheme for each championship season. In the current paper, an integrated methodology deploying statistical analysis and Data Envelopment Analysis (DEA) is proposed, for the purpose of evaluating and adjusting BoP schemes in any motorsports championship, primarily focused on GT racecars. The scientifically justified framework along with the simulated application resulting in a performance differentiation range of around 0.40 to 0.45%, comprise strong arguments for the validity and effectiveness of the proposed methodology. In this context, implementation of the proposed methodology by motorsports organizing bodies could potentially render the process of evaluating and adjusting BoP schemes more objective and consequently transparent.
Polishing Performance of Muğla White Marble with Different Abrasives
Authors: Çetintaş Sevgi 
Published: February 2025

Abstract
Abrasives play a critical role in the polish process of natural stone. Therefore, they can significantly affect the performance of polishing. In the thematic literature, there is no detailed study investigating the effect of abrasives from two different manufacturers in the same form on the natural stone polishing performance and wear characteristics of abrasive grain. The current study aims to fill this gap. Two abrasives are used on natural stone polishing process. Marble samples are polished in the same abrasive series, at constant belt and head pressure. Polishing performances of the abrasives are investigated based on surface roughness, surface gloss and the wear mechanism of abrasive grain. The study revealed that the Abrasive B present higher polishing performances in terms of the surface roughness and gloss on marble sample. The SEM analysis presented that the wear mechanisms of SiC grain are mainly attributed to abrasive wear, fracture wear and plucked out of abrasive. Additionally, it is concluded that polishing performance of the natural stone is highly affected by abrasive grain shape and grain distribution.

Published: February 2025

Abstract
The marine environment is facing serious changes. This requires scientific understanding of the ocean’s responses to pressures and management actions to provide the foundation for sustainable development. At the same time, the production of knowledge for a more sustainable world is undergoing rapid change with the uptake of citizen science as means of opening up science. While there is increasing interest in marine citizen science, it is also often conceived as lagging behind citizen science in other areas, such as biodiversity related citizen science on land. This paper analyses empirical evidence collected >1260 past and present marine citizen science initiatives, substantiating the pervasiveness of marine citizen science around the globe. In doing so, it provides the basis for a cumulative inventory of MArine Citizen Science Initiatives (MARCSI) that can inform and shape both the growing community of marine citizen science practitioners and the science of citizen science.

Published: February 2025

Abstract
Eutrophication of coastal areas is a global problem. A full-scale coastal remediation project was initiated in Björnöfjärden bay in the Stockholm archipelago in 2011. Measures to reduce external nutrient inputs from the surrounding catchment (15 km2) targeted agriculture, on-site wastewater treatment facilities, and horse keeping. The effects were evaluated at 22 water quality monitoring stations over 11 years (2012–2022) to determine temporal trends in nutrient concentrations, spatial correlations within and between monitored sub-catchments, and effects of individual mitigation measures at local and catchment scale. The effect of individual measures varied from no significant effect to significant nutrient decreases (21% reduction in dissolved P concentrations in one lime filter) or increases (11% higher concentrations in total P in one constructed wetland). However, few significant trends were detected at sub-catchment outlet stations. Tailored placement, design, dimensioning, and maintenance of implemented mitigation measures are needed to improve their nutrient retention effect.

Abstract
In recent years, conventional treatment methods have been reported as insufficient for effectively removing organic substances from water, emphasizing the potential of advanced oxidation processes as a promising solution. Therefore, the aim of this research was to evaluate the catalytic oxidation potential of graphene-encapsulated iron-based nanocatalysts synthesized from iron-containing salts using chemical vapor deposition combined with persulfate/UV-C for the degradation of total organic carbon in surface water. The microstructural and magnetic properties of the synthesized nanocatalysts were determined prior to their use as catalysts for advanced oxidation processes. The analysis results showed a significant total organic carbon removal ability, resulting in a reduction of up to 1.76 mg/L from an initial concentration of 4.55 mg/L under the conditions of pHo = 8.0, T = 25 °C, PS = 0.5 mM, and t = 60 min. Moreover, a decrease in UV254 during all experiments indicated that the organic matter present in the raw water, especially those with aromatic structures, underwent significant transformations during the catalytic processes.
