Examining Dark Triad traits in relation to mental toughness and physical activity in young adults
The Dark Triad (DT) describes a set of three closely related personality traits: Machiavellianism, narcissism, and psychopathy. Mental toughness (MT) refers to a psychological construct combining confidence, commitment, control, and challenge. High MT is related to greater physical activity (PA) and, relative to men, women have lower MT scores. The aims of the present study were 1) to investigate the association between DT, MT, and PA, and 2) to compare the DT, MT, and PA scores of men and women.
A total of 341 adults (M=29 years; 51.6% women; range: 18-37 years) took part in the study. Participants completed a series of questionnaires assessing DT, MT, and PA.
Machiavellianism, narcissism, and psychopathy were all significantly associated with higher MT scores (rs =0.45, 0.50, and 0.20, respectively). DT traits and MT were associated with more vigorous PA. Compared to men, women participants had lower scores for DT traits (overall score and psychopathy), while no differences were found for MT or PA in both sexes.
DT traits, high MT, and vigorous PA are interrelated. This pattern of results might explain why, for instance, successful professional athletes can at the same time be tough and ruthless.

Hydrogen production by sorption enhanced steam reforming (SESR) of biomass in a fluidised-bed reactor using combined multifunctional particles
The performance of combined CO2-sorbent/catalyst particles for sorption enhanced steam reforming (SESR), prepared via a simple mechanical mixing protocol, was studied using a spout-fluidised bed reactor capable of continuous solid fuel (biomass) feeding. The influence of particle size (300–500 and 710–1000 µm), CaO loading (60–100 wt %), Ni-loading (10–40 wt %) and presence of dicalcium silicate support (22.6 wt %) on SESR process performance were investigated. The combined particles were characterised by their density, porosity and CO2 carrying capacity with the analysis by thermogravimetric analysis (TGA), Brunauer-Emmett-Teller (BET), Barrett-Joyner-Halenda (BJH) and mercury intrusion porosimetry (MIP). All experiments were conducted with continuous oak biomass feeding at a rate of 0.9 g/min ± 10%, and the reactor was operated at 660 ± 5 °C, 1 atm and 20 ± 2 vol % steam which corresponds to a steam-to-carbon ratio of 1.2:1. Unsupported combined particles containing 21.0 wt % Ni and 79 wt % CaO were the best performing sorbent/catalyst particle screened in this study, when accounting for the cost of Ni and the improvement in H2 produced by high Ni content particles. SESR tests with these combined particles produced 61 mmol H2/gbiomass (122 g H2/kgbiomass) at a purity of 61 vol %. Significant coke formation within the feeding tube and on the surfaces of the particles was observed which was attributed to the low steam to carbon ratio utilised.

Resisting Uniformity: How Transgender and Gender-Diverse Teachers Subvert School Dress Codes for Self-Affirmation and Possibility
Transgender and gender-diverse teachers occupy a precarious position within educational spaces, often facing increased scrutiny and regulation aimed at disciplining their gender expression. This article brings to light original and significant insights by exploring how transgender and gender-diverse teachers resist and subvert cisnormative dress codes, as acts of self-affirmation and resistance within their professional educational contexts. Through an unconventional lens of Barad’s feminist new materialism combined with Wieringa’s continuum of symbolic subversion, our analysis offers an important theoretical contribution by interpreting how these individuals negotiate and challenge institutional cisnormativity, unsettling the tacit expectations of gendered professionalism in their trans embodiment. Drawing on the experiences of three transgender and gender-diverse teacher participants, a group often overlooked, this paper integrates findings from two distinct qualitative studies which used a participatory-focused ‘object-interview’ methodology. Findings from these in-depth studies reveal that transgender and gender-diverse teachers trouble dress code regulations by simultaneously embodying resistance and compliance, effectively reshaping and disrupting gendered expectations and institutional norms. While some forms of self-affirmation expressed by participants remained unseen, others materialised as embodied subversions of normative organisational expectations. Additionally, the degree of agency these teachers have in resisting binary dress code constraints is contingent on the entanglements of the teachers themselves, students, school policies, leadership and institutional climates. Unexpectedly, this research suggests that schools can act as sites of visibility and safety for transgender and gender-diverse teachers, where gender expression is validated and extends beyond the classroom. This article concludes by recognising that, when transgender and gender-diverse teachers resist uniformity and dress code norms, they embody their affirmed identities and, in doing so, offer vital representation for transgender and gender-diverse students, providing a sense of belonging, possibility, and authenticity within educational spaces.

Competition Anxiety in Combat Sports and the Importance of Mental Toughness
Combat sports require participants to engage in potentially dangerous forms of contact-based competition. Pressure to succeed, coupled with the risk of severe injury can induce significant levels of anxiety, which if uncontrolled, can negatively impact performance and possibly promote unsporting conduct. The present study examined competitive anxiety levels of combat sports athletes and determined whether self-reported scores were associated with mental toughness and Sportspersonship attitudes. A cross-sectional survey design was used whereby participants (N = 194) completed a battery of questionnaires measuring competitive combat sport experiences, demographic details, Sportspersonship traits (compliance towards rules, respect for opponents, and game perspective), and competition anxiety (somatic, cognitive, and self-confidence; reported retrospectively). Results suggest that mentally tough athletes experience lower levels of cognitive and somatic anxiety, and higher self-confidence, prior to competitions. Findings also found that athletes endorsing more altruistic and respectful attitudes in sport (Sportspersonship) reported higher levels of competition anxiety. The findings demonstrate that mental toughness is allied to positive attributes and could potentially be operationalized to improve both the retention and performance of combat sports athletes. Thus, the authors advocate the use of mental toughness coaching interventions within combat sports.

Potassium carbonate-based ternary transition temperature mixture (deep eutectic analogues) for CO2 absorption: characterizations and DFT analysis
Is it possible to improve CO2 solubility in potassium carbonate (K2CO3)-based transition temperature mixtures (TTMs)? To assess this possibility, a ternary transition-temperature mixture (TTTM) was prepared by using a hindered amine, 2-amino-2-methyl-1,3-propanediol (AMPD). Fourier transform infrared spectroscopy (FT-IR) was employed to detect the functional groups including hydroxyl, amine, carbonate ion, and aliphatic functional groups in the prepared solvents. From thermogravimetric analysis (TGA), it was found that the addition of AMPD to the binary mixture can increase the thermal stability of TTTM. The viscosity findings showed that TTTM has a higher viscosity than TTM while their difference was decreased by increasing temperature. In addition, Eyring’s absolute rate theory was used to compute the activation parameters (∆G*, ∆H*, and ∆S*). The CO2 solubility in liquids was measured at a temperature of 303.15 K and pressures up to 1.8 MPa. The results disclosed that the CO2 solubility of TTTM was improved by the addition of AMPD. At the pressure of about 1.8 MPa, the CO2 mole fractions of TTM and TTTM were 0.1697 and 0.2022, respectively. To confirm the experimental data, density functional theory (DFT) was employed. From the DFT analysis, it was found that the TTTM + CO2 system has higher interaction energy (|∆E|) than the TTM + CO2 system indicating the higher CO2 affinity of the former system. This study might help scientists to better understand and to improve CO2 solubility in these types of solvents by choosing a suitable amine as HBD and finding the best combination of HBA and HBD.
