- Here, we evaluate three different noble metal co-catalysts (Pd, Pt, and Au) that are present as single atoms (SAs) on the classic benchmark photocatalyst, TiO2. To trap the single atoms on the surface, we introduced controlled surface vacancies (Ti3+-Ov) on anatase TiO2 nanosheets by a thermal reduction treatment. After anchoring identical loadings of single atoms of Pd, Pt, and Au, we measure the photocatalytic H-2 generation rate and compare it to the classic nanoparticle co-catalysts on the nanosheets. While nanoparticles yield the well-established the hydrogen evolution reaction activity sequence (Pt > Pd > Au), for the single atom form, Pd radically outperforms Pt and Au. Based on density functional theory (DFT), we ascribe this unusual photocatalytic co-catalyst sequence to the nature of the charge localization on the noble metal SAs embedded in the TiO2 surface.

- To the Editors:As the authors of the article, “Typologies of Joint Family Activities and Associations With Mental Health and Wellbeing Among Adolescents From Four Countries,” we would like to provide a statement in light of recent events taking place in Eastern Europe [1]. Following the tragic events surrounding the war in Ukraine which started on February 24, 2022, more than half the country’s 7.5 million children have now been displaced [2]. At the time of this paper’s acceptance, hundreds of thousands of refugees making up mostly women and children have travelled to Slovakia, Czechia, and even Russia [3]; countries of focus in the current study. Families have been separated, and the once familiar routines of school and leisure for many Ukrainian children have been replaced with ensuring survival coupled with trauma and unfamiliarity. Lack of housing, malnutrition/hunger, exposure to infectious disease but also deprivation of education, sport, and leisure, are just some of the devastating impacts from armed conflicts on young people’s health and wellbeing [4]. Families from Ukraine will add to the growing number of refugees in the world, a group of over 21 million people who can often struggle with sociocultural differences in the countries they take refuge, as well as accessing information due to language barriers [5]. Many of the most common family activities for the children in our study, such as eating a meal and talking together, will likely present differently or have very different meaning among the hundreds of children who have arrived and will continue to come to these countries. Similarly, the mental health and wellbeing of both those from Ukraine and those from countries geographically close to the conflict will almost certainly suffer following these terrible events. Júnior et al. [4] highlight the importance of addressing children’s psychosocial needs, recommending parents create a safe space that allows for listening to children. As demonstrated in our paper, spending time together with family is important for adolescent’s health wellbeing and may be particularly crucial for families affected by the crisis. We hope that future research surrounding leisure time use and adolescent health considers the needs of marginalized and vulnerable groups of young people in particular, such as those affected and displaced by war and conflict.

- Purpose: This study aims to identify distinct typologies of joint family activities and the associations with mental health and wellbeing among adolescents across four countries from the World Health Organization European region.Methods: The 2017/2018 data from adolescents from Armenia (n = 3,977, Mage = 13.5 ± 1.6 years, 53.4% female), Czechia (n = 10,656, Mage = 13.4 ± 1.7, 50.1% female), Russia (n = 4,096, Mage = 13.8 ± 1.7, 52.4% female), and Slovakia (n = 3,282, Mage = 13.4 ± 1.5, 51.0% female) were collected in schools. The respondents self-reported their participation in joint family leisure-time activities, life satisfaction, psychological and somatic complaints, as well as a range of demographic and family situational factors. Stratified by countries, latent class analysis identified typologies of joint family activities, and logistic regression models explored cross-sectional associations with life satisfaction, and psychological and somatic complaints.Results: Three typologies were identified across each of the four countries, distinguished by low, moderate, and high levels of family engagement. Adolescents with higher family engagement generally reported greater life satisfaction and fewer psychological complaints compared to those with lower family engagement. Russian adolescents in the high family engagement typology reported fewer somatic complaints compared to those with low family engagement. In addition, adolescents from Czechia and Russia showing moderate family engagement also reported fewer psychological complaints compared to those in the low family engagement typology. Discussion: Our findings from four countries suggest that adolescents with high family engagement have greater life satisfaction and fewer psychological complaints, pointing toward a need for interventions to support family engagement among adolescents. Further research is needed to fully explore underlying mechanisms.
